Read our Editorial Guidelines to learn more about what makes our site the premier resource for online health information.

Weider Prime for Men is a testosterone (T) supplement sold by a company called Weider Global Nutrition. The brand describes their product as a “premium testosterone support formula” and highlights some of its active ingredients that are clinically tested for T support.

But does Weider Prime contain research-backed ingredients at appropriate doses for supporting T levels, or are these just marketing claims? Does the supplement contain any questionable additive ingredients? What retailer sells Weider Prime for the best price? And how do real users rate and describe the effects of Weider Prime?

In this article we’ll answer all of these questions and more as we analyze the ingredients in Weider Prime based on medical studies to give our take on whether the supplement is likely to be effective, or if it’s a waste of money.

We’ll feature unsponsored customer reviews, and provide a cost comparison to show what retailer currently sells Weider Prime for the best price.

Ingredient Analysis

Weider Prime vitamin and mineral ingredients

Weider Prime contains a large number of ingredients so we’ll break them down into sections. The vitamin and mineral ingredients are shown above.

Zinc is a mineral that may increase T levels if taken at doses much higher than that in Weider Prime, according to a medical review published in the Aging Male journal.

We cannot identify any convincing medical research suggesting that the other vitamins and minerals in this complex benefit T levels.

It may be illogical to take supplemental vitamins and minerals without evidence of a deficiency in those vitamins and minerals. A CBC report documented a different wellness brand that had to recall their products from the market because their overfortification with vitamins was causing toxicity in some customers.

The botanical ingredients in Weider Prime are shown below:

Diindolylmethane was shown to cause degeneration of testicular tissues in a 2016 animal study, albeit at much higher equivalent doses than that included in this supplement.

We can’t find any evidence that this ingredient increases or supports T levels and don't understand why it would be included in a T-boosting supplement.

Ashwagandha extract is clinically shown to increase T levels in men, and as we documented in our Ageless Male Max reviews article, a dose over 600 milligrams (mg) like what’s in Weider Prime has been shown to be effective.

Cordyceps extract has been shown in several clinical trials (source 1, source 2) to optimize T levels in animals, although we can’t find any studies proving the same effects in humans.

Piperine is used to increase absorption of other botanical ingredients.

The inactive ingredients in Weider Prime are considered non-toxic and are shown below:

Overall, we consider Weider Prime potentially effective for supporting optimal T levels in men. It contains one active ingredient we consider effectively dosed (ashwagandha extract), and one other active ingredient with some interesting preliminary research but that we can’t find direct evidence for in humans (cordyceps extract).

But how do real users rate and describe the effects of this supplement? We’ll review in the next section:

Real Customers Review Weider Prime

Amazon is a better resource for honest customer reviews than a brand’s website in our opinion.

Weider Prime has been reviewed over 1,500 times on Amazon, with an average review rating of 4.4 out of 5 stars.

The top positive review from a verified purchaser comes from a user named “big d d” who suggests the supplement resolved fertility issues they were experiencing:

“I work in the medical field had my T levels checked it was low. I started working out a lot and taking this product for about 6 months, a year later I am the proud father of a baby son.”

The top negative review from a verified purchaser is written by a user named “Kevin Hogan” who gives the supplement a 1-star rating and claims to have experienced side effects:

“These do not work, never will. Plus these gave me severe head cold like symptoms. Some say allergic to ingredients...either way...I stopped taking them and symptoms went away...took again...symptoms came right back. I decided to throw product away which was not an easy choice, considering the price.”

Questionable Marketing Claims on Weider Website

Weider Prime questionable health claim

As shown above, the product page on Weider’s website has a hyperlink with the text “Read the clinical study.” 

This strongly suggests that Weider Prime has been clinically tested, however the supplement does not appear to have been clinically tested. That link directs users to a page with clinical studies on some of the ingredients in Weider Prime, and we consider this marketing messaging to be confusing and unfair to consumers.

Some of the studies cited by Weider do not even show that the included ingredients support testosterone in otherwise healthy adults.

The clinical trial cited to support the inclusion of chromium does not even include the word “testosterone” once. It’s a study on metabolic changes including weight loss from chromium supplementation, not on the effects of testosterone changes.

The medical study on zinc supplementation did not show that zinc supplementation increased T levels in otherwise healthy adults, just in those already deficient in zinc. This suggests that men with low testosterone should get their zinc levels tested, not that they should take zinc supplements without knowing their current level.

There are no research citations on the product page or on this Clinical Studies page of the brand’s website to support the majority of the active ingredients in the formulation, including vitamin B6, vitamin B12 and diindolylmethane.

Where to Buy Weider Prime for the Best Price

Weider Prime is sold at a variety of online retailers. Here’s a per-capsule price breakdown at the time of publishing this article (because the supplement is sold at different capsule counts):

Brand website: $0.48 (plus shipping, link)

Walmart: $0.26 (plus shipping, link)

Amazon: $0.27 (free shippinglink to official Amazon listing)

Weider Prime is currently retailing for just over $30 on Amazon for a 120-count bottle, while it costs $28.99 for a 60-count bottle on the brand’s website. This makes Amazon the best option from a cost savings perspective by far, especially when factoring in shipping fees.

Does Weider Prime Cause Side Effects?

Weider Prime doesn’t appear to have been studied in any clinical trials, so it’s challenging to say whether or not the supplement is likely to cause side effects.

However, we can make an educated guess based on its ingredients.

Although we consider the practice of including high doses of vitamins and minerals in supplements to be questionable, we do not believe that this is likely to cause significant side effects.

Ashwagandha extract has a highly favorable side effect profile according to a 2021 clinical trial, and does not appear to cause any serious side effects.

We already noted that the inactive ingredients in these supplements are likely safe and non-toxic.

Overall, we consider Weider Prime unlikely to cause side effects in otherwise healthy adults. That being said, consumers concerned about side effects should clear its use with their doctor.

Our Testosterone Support Picks

Bulletproof Magnesium is our top testosterone support pick, because magnesium is a mineral that is clinically shown to increase free and total testosterone in athletes and in sedentary individuals.

Bulletproof Magnesium costs under $17 at the time of updating this article.

Momentous Tongkat Ali is our top herbal testosterone support pick, and costs under $20 at the time of updating this article.

Tongkat ali's effects on testosterone were reviewed in a 2022 meta-study, and the researchers concluded that "A significant improvement in total testosterone levels after [tongkat ali] treatment was mostly reported in both healthy volunteers and hypogonadal men."

Panax ginseng extract is an herbal libido enhancer, and was shown in a medical review published in the Spermatogenesis journal to increase sex drive in men when taken daily.

Illuminate Labs sells a Panax Ginseng Extract supplement which is third-party tested, and costs only $15 on a subscription basis.

All of the products recommended in this section are entirely free of additive ingredients that we consider unhealthy.

Conclusion

Weider Prime contains research-backed ingredients, but we can only identify one that appears to be included at a similar dose to medical studies.

We do believe this supplement is potentially effective at supporting healthy testosterone levels, given its effective dose of ashwagandha extract.

The supplement is free of apparently unhealthy additive ingredients and there are no ingredients we consider dangerous, so we consider the formulation to be healthier than the average T-boosting supplement formulation that we’ve reviewed on Illuminate Health.

There are a number of questionable marketing claims on the Weider website related to this product, including the suggestion that it’s clinically tested. It seems that some of the individual ingredients have been clinically tested, which is an entirely different circumstance than the entire supplement being clinically tested.

Most customer reviews we came across while researching this article were favorable.

For consumers intent on purchasing Weider Prime, Amazon currently has the best per-capsule price.
