Weider Prime Benefits

When taking Weider Prime, you can expect elevated testosterone levels, improved lean muscle mass, increased energy and focus, improved strength and recovery, and stress/cortisol reduction. 

Elevated Testosterone Levels

Clinically-tested KSM-66 Ashwagandha, along with some herbs, vitamins, and minerals (e.g., L-OptiZinc), is included to help return your low testosterone levels to healthy levels. Or, if you’re already at a healthy level, Weider Prime may increase this even further but within reference ranges. 

Improved Lean Body Mass

Weider Prime also claims to help you shred fat and gain muscle, thereby improving body composition. One of the main ingredients they claim will do this is Chromax, a patented form of Chromium Picolinate. 

Increased Energy and Focus

With ingredients such as B-complex vitamins, Weider Prime is also designed to increase your energy and focus from a physical and mental standpoint. Furthermore, Weider Prime may also give you enhanced aerobic endurance capacity.

Improved Strength and Recovery

Another benefit related to workouts/performance is increased strength. Weider Prime increases your recovery capabilities and enables you to work out harder and recover more effectively from intense workouts, improving overall body strength.

Reduced Stress and Cortisol

Finally, Weider Prime can reduce stress and help you attain healthy cortisol levels with its KSM-66 Ashwagandha content alongside other vitamins and minerals. 

Overall, you can see a host of claimed benefits from Weider Prime. But how well does Weider Prime perform when its ingredients are put under the spotlight? Read on to find out!

Weider Prime Ingredients

Weider Prime contains a combination of various ingredients, some of which are clinically tested and trademarked. Here is the rundown of what’s in Weider Prime:

(Note: Amounts are based on the serving size of 2 capsules.)

  • Vitamin D3 (400 IU)
  • Vitamin B6 (10mg)
  • Vitamin B12 (120mcg)
  • Calcium (35mg)
  • L-OptiZinc (15mg)
  • Chromax (200mcg)
  • Diindolylmethane (50mg)
  • KSM-66 Ashwagandha Extract (675mg)
  • Cordyceps Extract (390mg)
  • Bioperine (5mg)
Weider Prime Supplement Facts

Vitamin D3

The first ingredient listed in Weider Prime is vitamin D3. Vitamin D3, or Cholecalciferol, is involved in testosterone production, sperm production, and overall male reproductive health. Its primary source is from our skin when exposed to sunlight.

While you may not get as many IU’s as you would in a straight vitamin D3 supplement (most contain around 5,000 IU), the 400 IU amount in Weider Prime is 100% of the Required Daily Amount for adults. Research shows a positive correlation between vitamin D levels and testosterone levels; however, supplementation may only slightly affect testosterone levels. 

Vitamin B6 and B12

Weider Prime also contains two B-complex vitamins, B6 and B12. These vitamins are required for optimal energy levels since they help turn the food you eat into energy. Also, intense exercise increases the need for B vitamins, so supplementation can be beneficial during exercise and recovery. 

On top of that, these vitamins play a crucial role in brain and nervous system health, and supplementing at high doses of B6, B12, and other B vitamins enhances brain health.

Regarding testosterone, B vitamins are essential cofactors in several biochemical and enzymatic processes; hence, they may support efficient testosterone production.  


One mineral that Weider Prime includes is calcium. Calcium is utilized during exercise, and supplementation may be an efficient way to replace some of that loss. It is also needed for the functioning of various hormones and muscles and for exercise performance.

However, calcium supplementation likely won’t add anything significant to your workouts or testosterone levels, and Weider Prime only supplies about 4% of your RDA. 


Another mineral in Weider Prime is zinc in a specific trademarked form, L-OptiZinc. Zinc will likely have much more of a benefit than calcium as it has a critical role in the regulation of male reproductive functions. It is highly concentrated in the testes and essential for overall testicular function, testosterone production, and other androgenic hormones. It also helps convert testosterone to dihydrotestosterone. 

Furthermore, research shows zinc deficiencies are associated with hypogonadism (low T). Therefore, supplementation with zinc can be beneficial for those who are deficient, especially if you’re someone who exercises intensely.

The specific form of zinc included here, L-OptiZinc, is proven to be more absorbable and, thus, more effective. Healthy doses are around 15 to 30mg daily, sometimes even more. 


Up next is Chromax, a patented form of chromium picolinate. Chromium is a trace mineral involved in various aspects of metabolism that helps improve insulin function and increase muscle protein synthesis.

Research on Chromax specifically shows that it can help people lose fat and maintain lean body mass during weight loss, thereby improving body composition. The effective dose of Chromax is 200 to 400mg daily. 


Weider Prime also contains an ingredient called diindolylmethane (DIM). DIM appears to affect estrogen metabolism, in which it can increase “good” estrogens and decrease “bad estrogens.” There really isn’t any definitive research showing it can improve free or total testosterone levels, and its benefits are mainly speculative currently. 

KSM-66 Ashwagandha

Perhaps the most potent ingredient in Weider Prime is KSM-66, a specific form of ashwagandha extract. Ashwagandha is a very powerful and healing herb that has been used for thousands of years in Ayurvedic medicine worldwide.

It mainly acts as an adaptogen, which means it can control stress via action on the HPA axis. Research shows that the most beneficial effects of ashwagandha are stress and anxiety reduction, including reductions in cortisol. And lower stress/cortisol should lead to greater testosterone levels since cortisol can inhibit testosterone.

Indeed, ashwagandha is known to increase free and total testosterone and promotes better physical performance, including increased strength and endurance and less fatigue. Overall, it is a very effective ingredient, and the KSM-66 form is the most well-researched.

A typical dose for men is 300 to 600mg, the latter being more effective. So, where other testosterone boosters include a smaller dosage, such as Prime Male with 300mg or Nugenix Maxx with 600mg, Weider Prime aims to pack a punch with this ingredient by including 675mg.   


Next up is cordyceps, a mushroom that, like ashwagandha, has been used for many years, typically in Asian medicine. Cordyceps has several benefits, such as decreasing inflammation and improving blood sugar and cholesterol levels, which could promote enhanced body composition.

Cordyceps has also been used for male infertility, and some research shows that it can improve sperm health and increase sexual desire. 


The last ingredient in Weider Prime is BioPerine, a trademarked form of piperine, a compound found in black pepper. BioPerine is used in many supplements to enhance the absorption of vitamins, minerals, and other ingredients.

In fact, many of the ingredients in Weider Prime are proven to be absorbed better when co-administered with BioPerine, such as zinc, calcium, vitamin B6, vitamin B12, and ashwagandha. Therefore, BioPerine plays a vital role in this product. 

Does Weider Prime Work?

Weider Prime is a pretty solid product and is likely to work as a testosterone booster and overall male health promoter. It includes a good group of ingredients proven to increase testosterone, energy, and performance, among other things, mainly KSM-66 Ashwagandha, L-OptiZinc, and probably cordyceps.

Chromax is another high-quality, well-researched ingredient that should promote fat loss, and all of these ingredients are dosed based on the clinically researched effective dose, so this is a big plus. 

However, there are a few subpar ingredients, like calcium and DIM, as their benefits on testosterone production are not entirely ascertained, so we wouldn’t expect much from them.

Claims vs. Reality

Weider Prime has many proposed benefits, including elevated testosterone levels, improved lean body mass, increased energy and focus, improved strength, recovery, and overall performance, and lower stress and healthier cortisol levels. 

With some key, high-quality ingredients, most of these claims can be stood by. You’ll likely get a boost in testosterone from KSM-66 Ashwagandha, L-OptiZinc, and cordyceps. KSM-66 should also help with increased energy and focus as well as various aspects of exercise performance. Vitamins B6 and B12 may also help with energy, focus, and exercise performance, but they may not be too noticeable. 

Chromax is primarily included as a body composition supplement and will likely do just that. You should notice at least slight reductions in body fat and an overall improved body composition.

Finally, KSM-66 comes in again with its ability to lower stress and establish healthier cortisol levels. This is the best ingredient in Weider Prime. 

How Do You Take Weider Prime?

You should take two Weider Prime capsules daily with food in the morning or afternoon.

How Fast Does Weider Prime Work?

You should notice Weider Prime’s benefits as soon as four to eight weeks after you begin taking it.

Who is Weider Prime Best For?

With its multi-faceted and specific list of benefits, Weider Prime is best for middle-aged to older men who simply want to look, feel, and perform better. Take a look at the benefits you may get: More testosterone, improved body composition, better energy and focus, enhanced exercise performance, and lower stress.

And what is so very common among middle-aged and older men today? Quite the opposite of these things: Low T, higher body fat, brain fog, sluggishness, decreased exercise capacity, and high-stress levels. This is why Weider Prime is best for these men. But make no mistake, Weider Prime won’t cure you of everything going wrong. Weider Prime will help give you that extra “boost” alongside adopting a healthy diet and lifestyle. 

Weider Prime - Best for Middle Age Men

Is Weider Prime Safe?

There are a few side effects to look out for when taking Weider Prime:

  • The main side effects of vitamin D are nausea, vomiting, and weakness
  • B6 and B12 may also cause mild gastrointestinal symptoms and may promote restlessness, irritability, and related symptoms
  • Zinc, Bioperine, cordyceps, and ashwagandha can cause nausea, vomiting, diarrhea, and other stomach symptoms
  • The most common side effect of DIM is the darkening of urine

Where to Buy Weider Prime
