Any GNC Mega Men Sport Lawsuits?

GNC has a lot of issues due to the lawsuits that were surfacing in 1998 on the worldwide media.

They stated that the company was making and designing its franchisees such that an increase and elevation in the sales and the business of the company could be seen.

In 2003, an article was published which stated that the GNC Company was issued some legal claims and disputes by many of its distributors and franchise homeowners.

The company was declared to be working in harmony with many smaller distributions and franchises, and these lower distributions and franchises were charging extra money from people regarding the profit which was illegal.

So, the customers took the issue to the higher authorities to lay complaints. This led to an outrage where public began to boycott the company’s products.

The main issue was with Picamilon and BMPEA which are a part of the products of the company.

These are the unapproved drugs of the FDA, but they have been a part of the supplement due to which a complaint was filed by the professional General of Beaver State in 2015.

The inclusion of a prohibited ingredient as a part of the supplement leads to the limitations and restrictions of this supplement from the athletes of NFL.

Athletes have claimed complaints about the products and their adverse effects. There is a sound lack of proof, so trials are underway.

They will be performed to ensure the efficacy and efficiency of the products from the company.

Although Human experiments are not enough to make it an excellent choice to be used on a commercial scale, it will undoubtedly bring back the trust of the people to the product.

Make sure that you consult a doctor before using the supplement to avoid all the side effects and adverse effects which could result when taking the supplement long-term.

GNC Mega Men Sport Alternatives

All the supplements that are available in the market have their effects on the health of men somehow.

If you are a man in his 30’s, you will feel that your body is getting more tired and worn out at times.

Advocare Spark also works to enhance your mental agility and body coordination.

“I have been using GNC Mega Men Sport for years, either purchasing them at the local GNC store or on the military base I can shop on. The difference was I could get them from Amazon Prime at a cheaper price. Same excellent quality. For a active, fit guy over 60, I like what GNC Mega Men Sport provides for me.”

“This product causes me severe abdominal pain with associated nausea. I have never experienced such bad abdominal pain before and thought I had developed some kind of illness or stomach issue. I continued to take my vitamins and the pain got worse. I stopped taking everything and the pain subsided then slowly introduced things back into my daily routine. Within half hour of taking the vitamins, the severe abdominal pain and nausea was back again. I’m not sure which of the ingredients is causing this as I’m 32 and taken men’s daily vitamins my entire adult life.”

“I like it but the highlighter colored pee gets me worried, these guys went overboard on the vitamin b idk if thats a healthy thing longterm.”

Their women’s multivitamin reports being clinically studies, energy boosting, calorie torching, and antioxidant packed. And they also claim to help with other things like hair strength and bone health.

We decided to check it out.

Note: Multivitamins shouldn’t be seen as replacements for a healthy diet or medication. It’s always a good idea to talk to your doctor before beginning a new fitness, nutritional, and/or supplement routine. Individual needs for vitamins and minerals will vary. The list below simply includes our favorite brands and shouldn’t be taken as medical advice.


Women’s Ultra Mega Energy & Metabolism was formulated with a solid blend of B vitamins, antioxidants, and two concentrated “superfood” blends including an antioxidant blend and energy and metabolism. Of it’s ~30 ingredients, the supplement offers 100% or more of your recommended daily values for 21 vitamins and minerals, and 200% or more of your recommended daily values for 9.

Below, we highlight some the ingredients in Women’s Ultra Mega Energy & Metabolism, including the ones we deemed as being particularly noteworthy or interesting.

Image from

Vitamin D 1600 IU

Vitamin D is involved in almost everything we do like building proteins and enzymes, boosting the immune system, and fighting inflammation, all of which are integral to athlete recovery and Women’s Ultra Mega Energy & Metabolism offers 400% of your daily needs. Because it’s hard to get the right amount from food, you have to get the rest of your daily needs through sun exposure (which is tricky during the winter) and supplementation.

Folic Acid 400 mcg

Whether you’re growing out your nails, fighting depression, or looking to fight inflammation, you want this ingredient in your multi. As athletes you know that some inflammation is good, but too much isn’t, so folic acid may be a plus to active women.

GNC Women’s Ultra Mega Energy & Metabolism GNC Women’s Ultra Mega Energy & Metabolism

The GNC Women’s Ultra Mega Energy & Metabolism offers a wide variety of useful ingredients to power your overall health and daily energy.

Biotin 300 mcg

ICYDK, that’s a lot of Biotin. 100% of your daily needs to be exact. Biotin is good ingredients luscious locks and it has been shown to boost nail health, which is why it’s typically included in women-specific multi’s.

B Vitamins

The B vitamins referred to as “B complex” are crucial for optimal health, helping our bodies convert our food into fuel and promoting healthy skin, memory, pregnancies, and more.

GNC claims that this multi is “packed with B vitamins to support energy production” and research suggests that B Vitamins may actually have that effect. In addition to Vitamin B7 (Biotin) and Vitamin B9 (Folic Acid), in this multi you can expect to find 50 mg of Vitamin B1 (Thiamin), 50 mg of Vitamin B6, 50 mg of Vitamin B12, 50 mg of Riboflavin (Vitamin B2) , 50 mg of Niacin (Vitamin B3), 50 mg of Pantothenic Acid (Vitamin B3), and 400 mcg of Folic Acid (Vitamin B9).

Image from

Calcium 500 mg

500 mg of Calcium may only be 50% of your daily needs, it’s actually super rare to see this ingredient in a multivitamin.

Zinc 25 mg

Raise your hand if you’re stressed out. If your hand is up, you may be low in this mineral. Athletes may also be deficient, because exercise may makes us feel great, but it’s still a stressor on our bodies, so athletes in particular tend to be deficient. Why is that an issue? Not enough zinc may dull your taste buds, which ups the chances that you’ll add sugar or salt to your food so getting 25 Mg (or 167% daily values) is a definite positive.

Magnesium 100 mg

Low levels of calcium and magnesium (which often go hand in hand) are known for sparking sugar and salt cravings. Low magnesium levels in particular are known for upping those chocolate cravings. And while a serving of chocolate protein powder is NBD, a chocolate bar every single day might be.

Molybdenum 75 Mcg

This is probably the most surprising ingredient on the list, because it’s not often included in multivitamins, that’s because humans don’t need much of it, and what we do need we usually get from food. It’s basic role is to help us break down fats and carbs for energy. But it’s also abundant in human tooth enamel and may have a role in lowering the risk of tooth decay (NBD for women in their 20’s, but might be important for women 50+).

Super Antioxidant Blend

If you’re wondering what the heck this is, according to GNC, it’s a blend packed with 25 mg alpha-lipoic acid, 2mg of Lutemax® 2020 Lutein, 1 mg of lycopene, 500 mg of turmeric root extract, 400 mcg zeaxanthin, 50 mcg of Astaxanthin, and 10 mg of beta-Cryptoxanthin. Here’s the things: there’s no research specifically how these ingredients work together in a blend. But science has shown consuming antioxidants may be good for your heart health, may help lower your risk of infections and some forms of cancer, and could help with inflammation.

Pill size for GNC Multivitamin

Energy & Metabolism Blend 137 mg

The multi’s namesake, this blend is made up of caffeine anhydrous, green tea extract, eleuthero root extract, and black pepper fruit. To be clear, “caffeine anhydrous” is really just a highly concentrated caffeine powder. Like HIGHLY concentrated. According to the U.S. Food and Drug Administration (FDA), a teaspoon of caffeine anhydrous is the equivalent of 28 cups of coffee.

One serving, or 2 pills of GNC Women’s Ultra Mega Energy & Metabolism, packs 100mg of caffeine, which is about the amount of caffeine equivalent to a 6oz cup of coffee.

As for the other ingredients in this blend? Green tea extract is high in antioxidants and some research suggests that the green tea & caffeine combo may be beneficial for weight loss. Eleuthero root extract is an adaptogen that isn’t well studied, but it’s worth noting that while some studies support the conclusion that adaptogens have promise and potential at reducing stress, improving attention, upping endurance, and fighting fatigue. Black pepper fruit also lacks much research-backed claims, but some websites claim it aids in digestion.

Other ingredients include:

  • Vitamin A 5000 IU
  • Vitamin C 200 mg
  • Vitamin K 80 mcg,
  • Iron 18 mg
  • Selenium 200 mcg
  • Copper 2 mg
  • Manganese 2 mg
  • Chromium 120 mcg
  • Vitamin E 30 IU
  • Choline 10 mg
  • Inositol 10 mg
  • Silic 4 mg

It’s also worth noting that the vitamin contains cellulose, stearic acid vegetable source, magnesium stearate vegetable source, titanium dioxide (natural mineral whitener), natural vanilla mint flavor, talc, chlorophyll, stevia leaf extract for taste and shape. Additionally, this product may contain traces of soy and is not vegetarian.

Women’s Ultra Mega Energy & Metabolism Benefits and Effectiveness

CrossFit is my jam. Hot yoga is my new Sunday tradition. Running over the Queensborough bridge is my idea of active recovery. And for me, no day in Central Park is complete without a little game of touch-rugby or frisbee. I may not be as active as a CrossFit Games Athlete, but “active” is likely an understatement.

With my activity level in mind, and the fact that I’ve been taking Flintstone gummies since I was a kid, it’s no surprise that I’m always looking for a supplement to boost my health ( BTW, did you know that 30% of millennial women report taking a multi?). Last month, I decided to try a relatively inexpensive product with big claims (and positive reviews) about increasing energy: GNC Women’s Ultra Mega Energy & Metabolism.

If this pill was a Tinder date, I’d definitely take it out on a second date. Which is to say, it makes a killer first impression. It has a nice seagreen color, smells like mint, tastes like pre-chewed minty gun (which honestly isn’t terrible compared to other multi’s). Let me repeat myself. This multi doesn’t smell or taste like garbage Or old arugula. Or canned tuna. It smells like mint. Mint!

Yep, I’m officially making my standards higher.

As for the size, it’s big but not too big (*insert that’s what she said joke here*). It’s certainly larger than an your average OTC pain reliever, but I’ve seen (and tried) larger. Visualize of the size of a singleMike & Ike, and you’ll have a decent sense of the size of these buggers.

The bottle says, “take two tablets with food”, so I didn’t stray from the instructions to see how it would affect my tummy without breakfast. But when I took the pills with a breakfast of collagen protein smoothie or 2 spoonfuls (okay, fine, 2.5) of almond butter, I had no stomach issue. And whenever a supplement doesn’t affect my digestive system, I’m seriously ecstatic. So this was a total win (especially considering the pill contains iron, which my stomach has reacted poorly to in the past).

After reading other reviews of the products, I expected Women’s Ultra Mega Energy & Metabolism to increase my energy levels because the product contains 100 mg of caffeine and the reviews were pretty positive. One women said “This product made me jittery” while another noted “As a Mom of 5 young children I was feeling very much worn down and exhausted all the time, I was finding it hard to get all my chores done and I was always needing naps, I knew I needed to do something so I started searching for a Vitamin As soon as I got them, I started taking them and immediately noticed a huge difference in my energy”. And a third wrote, “I DO have a bit more energy than normal. A little more pep in my step, if you will.” But, I’m going to be honest…I didn’t feel any noteworthy effects. Perhaps that’s because consuming two 12 ounce coffee a day is my norm, so the extra caffeine simply didn’t affect me the way it might someone who regularly consumes less caffeine.

The biggest downfall is that I sort of felt like I was flushing all (or at least, most) of the nutrients in the pills down the toilet. A quick science lesson: When it comes to vitamins and minerals, how well we’re able to absorb nutrients, matters a lot (it’s called bioavailability). When we can’t properly absorb the nutrients, we end up excreting them in a funny-colored stream. If my neon-yellow pee-color is any indication, my body wasn’t actually able to absorb the vitamins in Women’s Ultra Mega Energy & Metabolism. That said, Amazon reviewers are notoriously honest, and there weren’t any reviews that mentioned the that the pill turned their pee neon yellow, so you may not have this side effect. While I didn’t feel the same pep-in-my-step the way Laura from Amazon did, I certainly didn’t feel any worse.

Another potential downfall of this product is that it includes a few blends of ingredients which are not well researched. But that’s the vitamin industry for you and the same can be said about many products in the supplemental market are not well researched, so this should not come as a surprise.

Women’s Ultra Mega Energy & Metabolism Price

48 cents a day. $3.36 per week. $14.40 per month. That’s how inexpensive this multivitamin is. Seriously. That’s less than a salad at lunch (or at least a salad at lunch in New York City…).

The Takeaway

I think that this product is a great deal. At less than 50 cents a day, it’s among least expensive multivitamins I’ve tried. And it has ~30 different ingredients, 21 of which offer 100 percent or more of recommended daily values. Given the price and ingredient content, I don’t see many drawbacks in incorporating this vitamin into your wellness routine, unless your caffeine sensitive. Plus, it tastes and smells good.

The only two downsides here are the size, so if pills are your nemesis, this baby probably isn’t for you because you have to take two. And the fact that it’s not vegetarian or vegan, which depending on your dietary preferences may be an issue for you.

Do multivitamins make you healthier?

Updated: December 16, 2019Published: March, 2014

Some experts say it’s time to give up on daily multivitamins to preserve health, but others disagree. What should you do?

If you take a multivitamin, it’s probably because you want to do everything you can to protect your health. But there is still limited evidence that a daily cocktail of essential vitamins and minerals actually delivers what you expect. Most studies find no benefit from multivitamins in protecting the brain or heart. But some Harvard experts think there is still hope.

“There are potential benefits and there are no known risks at this time,” says Dr. Howard Sesso, an associate professor of epidemiology at the Harvard School of Public Health. “It is worth considering a multivitamin as part of a healthy lifestyle.”

Caught between expert opinions, what do you do? Start with asking yourself why you would consider taking a multivitamin. If you suspect your diet is nutritionally lax, focus your efforts there.

What we know about multivitamins so far

Despite all the research on vitamins and health, we have only a handful of rigorous scientific studies on the benefits of what Dr. Sesso calls a “true” multivitamin: a pill that provides essential vitamins and minerals at the relatively low levels that the body normally requires.

The Physicians’ Health Study II is the best study completed so far. It was the first and only large-scale randomized clinical trial to test a commonly taken multivitamin like the ones most people take, containing the daily requirements of 31 vitamins and minerals essential for good health.

A large group of male physicians took either a multivitamin or a placebo pill for more than a decade. The results have been mixed, with modest reductions in cancer and cataracts, but no protective effect against cardiovascular disease or declining mental function. Is it safe?

Multivitamin advocates point to the lack of any strong proof that taking a multivitamin for many years is dangerous. “While I agree that the likelihood of harm is small, the likelihood of a clear health benefit is also very small—and also we have no clear proof yet of such benefit,” says Dr. Guallar, a scientist at the Johns Hopkins Bloomberg School of Public Health.

Dr. Sesso speaks for the optimists, who urge a wait-and-see approach. “Multivitamin supplementation is low risk and low cost, and it helps to fill potential gaps in the diet that people might have,” Dr. Sesso says. “These are compelling reasons to consider taking a multivitamin for cancer and eye disease that should be discussed with your physician.”

For now, you can take certain steps:

  • Ask your doctor if you really need to take a multivitamin. Could you have a vitamin deficiency?
  • Assess your diet. Do you eat as healthy as you could? Is anything lacking?
  • Do you want expert nutritional advice? See a dietician. Also, Medicare beneficiaries get an annual “wellness” visit with their primary care providers.
  • Do not take high doses of specific vitamins, especially A and E. These may actually be harmful.

What does the evidence suggest?

Physicians’ Health Study II

Researchers looked at the effect of long-term multivitamin use in healthy men on various aspects of health. Here is what they found:

  • Cancer: Men were 8% less likely to be diagnosed with cancer. The protective effect was greatest in men with a history of cancer.
  • Vision: Lower risk of developing cataracts.
  • Cardiovascular disease: No protection against heart attacks, strokes, or death from cardiovascular disease.
  • Brain: No protection against declining memory or mental skills.
  • Caveat: Because of PHSII’s design, the findings on memory loss and vision are somewhat more likely to be chance findings than the cancer and cardiovascular disease results.

July 1, 2009— — In recent years, both research on and the availability of vitamin supplements has increased, drawing increased attention to the possibility that a daily pill can enhance health.

In particular, it is a message that is resounding with men. According to the Council for Responsible Nutrition, 53 percent of American adults take a multivitamin supplements, and 50 percent of adult men 18 and older take a multivitamin, according to a 2008 survey.

But preliminary encouraging findings can often hit a wall when they are refuted by larger studies that lead to increased scrutiny on products whose claims overstated the benefits of that early research.

The latest product to enter the crosshairs of a watchdog group is Bayer’s One A Day Men’s Health Formula supplements, which are promoted as containing “Selenium to support a healthy prostate.”

Those claims came under fire from the watchdog group the Center for Science in the Public Interest after two studies on selenium came out in June in the Journal of Clinical Oncology, one of which showed selenium provided no benefit and one which showed that for men with a certain gene variant — one found in three quarters of men — selenium supplements made the prostate cancer worse.

The authors of the second study, from the University of California, San Francisco, concluded that their findings “indicate caution against broad use of selenium supplementation for men with prostate cancer.”

CSPI released a statement earlier this week in conjunction with a complaint to the Food and Drug Administration.

“Bayer must be stopped from promoting its selenium-containing products as a means of reducing prostate cancer risk and promoting prostate health,” senior nutritionist David Schardt said in the statement. “Not only does selenium not prevent cancer, supplementation with selenium may be harmful.”

Schardt told ABC News that other supplements have similar problems, such as supplements that contain gingko, whose claims for increasing memory and concentration have not been confirmed by studies.

At this point, he said, the very notion of a men’s supplement is faulty.

“Do you need to take a men’s supplement?” Schardt said. “A basic adult multivitamin does well for both men and women. The nutrient needs are not that much different.”

As of press time, Bayer HealthCare had not responded to a request for comment.

But Andrew Shao, a nutritionist and vice president of scientific affairs for the vitamin trade group the Council for Responsible Nutrition, countered that while claims of selenium preventing prostate cancer have not been proven, they are not completely baseless, having been displayed by some observational studies.

He said that the randomized trials necessary for proof are expensive and, therefore, difficult to conduct. But “That doesn’t mean there are no data to support the relationship.”

Dr. Donald Hensrud, chair of preventive medicine at the Mayo Clinic, said that without that evidence, there is no clear health benefit from men’s supplements.

“One popular men’s vitamin contains a little more of certain nutrients to help the prostate, heart, and blood pressure,” he said. “However, although there may be some mild evidence associating those nutrients with these conditions, there are no randomized controlled trials showing better health outcomes in subjects who took those nutrients.”

What about the Multis?

A similar dearth of evidence can also be found in a more popular pill — the daily multivitamin supplements that provide one day’s serving of vitamins.

“It is the most popular dietary supplement,” Council for Responsible Nutrition spokeswoman Judy Blatman said.

But while the pills may be popular, the benefits of taking them remain largely unproven.

While health experts are in general agreement that multivitamins may provide some benefit in insuring people get at least minimal daily intakes of vitamins and minerals, they have not shown any long-term benefits, according to Howard Sesso, an epidemiologist at Brigham and Women’s Hospital and assistant professor of medicine at Harvard Medical School who has researched the topic in a number of large studies.

“We know, for the most part, that multivitamins are seen as a kind of insurance against any deficiency that might be present,” he said.

But any benefits beyond that are purely speculative.

“We still don’t know definitively whether taking a standard multivitamin does anything in the context of preventing chronic disease,” Sesso said.

Suzanne Murphy, an epidemiologist with the Cancer Research Center of Hawaii who has looked into vitamins and cancer prevention, came to a similar conclusion.

“Most people in the United States eat fairly well, they eat well enough to avoid deficiency, Murphy said. “They may not be eating optimal diets, but you’re not going to really replace some of those poor dietary habits with a multivitamin pill. There’s something about fruits and vegetables that goes beyond the nutrients, at least the ones that we’ve identified.”

“I don’t think a multivitamin, at a reasonable level, that just supply’s a days worth of vitamins and minerals, is harmful,” she said. “If that’s something you want to spend your money on and sort of makes you feel you have some insurance, that’s fine.”

Shao said vitamins are needed because people don’t weigh out their food daily to analyze the nutrients.

“I don’t know for sure if I’m getting all the nutrients that I need from my diet,” he said, noting that he is more acquainted than most people with the dietary guidelines.

“I can’t eat the way that dietary guidelines say I need to eat,” Shao said. “Frankly, it’s virtually impossible. That’s where using a multivitamin to help fill in gaps that we know are there.”

He noted that vitamins have not been found to prevent chronic diseases, but he doesn’t expect them to be.

“Nobody has teased out … the single cause for a chronic disease, because there isn’t a single cause. It’s a number of different things,” Shao said.

To Take or Not to Take?

While whether to take a daily multivitamin supplement remains up in the air, one thing researchers agreed on was that the pills were no substitute for eating better foods.

“A multivitamin is not a substitute for a good diet,” Schardt said.

He said they may provide insurance, but cannot be a frontline diet change. “If you have automobile insurance, that doesn’t mean you can drive like a maniac. You still have to exercise common sense.”

But other researchers believe that an emphasis on adding vitamins isn’t tackling the bigger health issues.

“It’s rather few cases … where multivitamins have been put to test in a clinical trial to date. None have really shown benefits for any clinical outcome like cancer or heart disease,” said Ross L. Prentice, a biostatistician with the Fred Hutchinson Cancer Research Center and the University of Washington who has been involved in some long-term studies of the effects of multivitamins on the risk of disease.

“There may be some short-term benefits people report but, in terms of chronic diseases, I don’t think so,” Prentice said.

Prentice said he is skeptical of the vitamin-based approach to improving health, despite the number of primary care physicians — including his own — who have recommended taking more vitamins.

“I think it’s a large, expensive industry without convincing data. Billions of dollars in expensive urine so far,” he said.

“I think we should be looking into commonplace things like how many calories we consume … how much physical activity we get,” he said. “Those are difficult topics to study reliably, but they’re likely the keys to our obesity epidemic and obesity-related diseases.”
