Weider Prime Testosterone Booster Review

It’s well known that inadequate testosterone levels have a detrimental effect on men’s quality of life, but with so many testosterone boosters on the market, it can be difficult to choose the right product for you. We’re going to review if Weider Prime is worth your time, and the short answer is no. Instead, we recommend Testofuel or anything else on our list of the best testosterone booster supplements for men.

Positives

1. Non-proprietary blend that includes ashwagandha
2. Available to purchase online from the manufacturer website or Amazon, or in select physical stores such as Costco
3. Relatively cheap however this is reflected in the quality

Negatives

1. Missing common key ingredients such as magnesium, fenugreek, ginseng, and vitamin K
2. Contains various ineffective ingredients like vitamins B6 and B12, and zinc that have no impact on healthy testosterone levels
3. Potentially beneficial ingredients are heavily underdosed, especially vitamin D at 8 times lower than recommended and cordyceps extract at 3 times lower
4. The single serving a day schedule means the minor benefits are short lived
5. Unsuitable for vegetarian, vegan, halal or kosher diets

Weider Prime Ingredients Overview

The serving size is 2 capsules taken once a day, and one of these servings contains: Vitamin D3 (400IU 100% Daily Value), Vitamin B6 (10mg 500% DV), Vitamin B12 (120 mcg 2000% DV), Calcium (35mg 4% DV), Zinc (15mg 100% DV), Chromium (200mcg 167% DV), Diindolylmethane (DIM) (50mg), Ashwagandha Root Extract (KSM-66) (675mg), Cordyceps Extract (Mycelia) (390mg), Piperine (Bioperine) (5mg).

The Weider Prime testosterone support formula is non-proprietary, meaning all ingredients and their dosages are clearly labelled. We love this and strongly suggest you only take supplements that provide such information, although it doesn’t do this product too many favours as it exposes the flaws of its ingredients list.

Weider Prime omits most of the commonly used and scientifically proven test booster ingredients such as magnesium and vitamin K, in favour of a selection of weaker or just ineffective ingredients. Included ingredients that do have the potential to help raise testosterone to within the normal range, such as vitamin D and calcium, are underdosed. Ensuring optimum dosage is a large part of why supplements of this kind are usually taken in 3-4 daily servings instead, along with the more obvious benefit of a consistent intake of nutrients. Weider Prime also uses bovine gelatine capsules, making it unsuitable for a vegetarian, vegan, halal, or kosher diet, although it is gluten free at least.

Weider Prime Ingredients Analysis

Vitamin D – Evidenced to boost testosterone levels, mood and overall vitality, amongst other health benefits, at doses of 3332IU (83mcg) and above [1]. Weider Prime falls incredibly short here with a measly 400IU (10mcg).

Vitamin B6 – Supports the production of serotonin and dopamine but doesn’t directly contribute to testosterone levels.

Vitamin B12 – Supports the production of energy and red blood cells, but again it doesn’t directly contribute to testosterone levels.

Calcium – A pointless filler ingredient with no impact at just 4% of the recommended daily intake.

Zinc – This essential mineral has tons of health benefits, and Weider Prime contains L-Optizinc, a chelated form with high absorption rates. However, studies have shown that these benefits may not extend to testosterone [2].

Chromium – Regulates blood sugar and can decrease body fat so is commonly found in fat burner supplements but doesn’t really have a place in testosterone boosters.

Diindolylmethane (DIM) – Some vegetables contain indole-3-carbinol (I3C) which our bodies break down into various compounds including DIM, which can assist with balancing our testosterone and estrogen levels [3]. Conversely though, I3C in its original form is thought to be more effective at lowering estrogen than DIM is, and some studies have suggested that direct DIM supplementation can even raise estrogen [4]. So yet again, this wasn’t the most well thought out inclusion.

Ashwagandha (KSM-66) – Traditionally used for lowering cortisol, the stress hormone. Similarly to how extreme deficiencies of some of the vitamins in Weider Prime can cause low testosterone, chronic levels of cortisol can do the same. Reducing cortisol may offer more ‘space’ for other hormones to develop, including testosterone, and some studies have suggested that it can also directly boost the testosterone levels and lean muscle mass of weight-training men [5].

The bad news though is that the dosage here is very high for anyone without a pre-built tolerance, so it is likely to cause drowsiness, which isn’t what you want before a workout. 300mg, less than half the dose found in Weider Prime, is more commonly recommended for a new user. Long term high dose usage has also been linked to some unpleasant withdrawal symptoms such as shortness of breath, anxiety, and sickness, if you don’t gradually wean yourself off.

Cordyceps – Another ingredient more commonly found in fat burners as it can boost energy and stamina. Weider Prime contains cordyceps mycelia, which is nutritionally much weaker than the ‘fruiting body’ variety [6], and even if it did contain the nutrient-rich fruiting body, the dose provided is still almost 3 times lower than the minimum recommended daily intake.

Piperine – Black pepper extract has no impact on testosterone production, nor does it have any other notable health benefits, so why does this ingredient find its way into many supplements? It has an uncommon and incredibly useful ability to increase your body’s absorption rate of the various nutrients found in other ingredients [7].

Weider Prime Safety and Side Effects

Testosterone boosters are generally very safe when taken as directed. You should always check the ingredients for personal allergens and consult your doctor before taking new supplements if you are worried about them clashing with any medication or health conditions.

One bottle of Weider Prime contains 60 capsules, which is a one-month supply, and the directions suggest taking 2 capsules with food once a day, either in the morning or afternoon. The product website offers no information regarding where and to what standard it is produced, which is a little concerning, however the brand is well established so we will give the benefit of the doubt.

Whilst this product does have an array of 5-stars customer reviews praising better physical performance and faster workout recovery, it also has lots of 1-star reviews, and many of these centre around nasty side effects. The likely culprits of this are DIM, chromium, ashwagandha or cordyceps, and there have been plenty of reports of stomach upsets, sickness, drowsiness, and severe headaches, and some customers have complained of more serious issues like poor blood clotting and high blood pressure.

Weider Prime Testosterone Support Review Conclusion

Weider Prime is missing proven testosterone boosting ingredients like magnesium and fenugreek, and instead contains various ineffective ingredients like vitamins B6 and B12. The small, once a day serving size also means the minor benefits of this product are inconsistent and the few decent ingredients such as vitamin D ended up being very underdosed. There are also a few ingredients that have a reasonable chance of causing unpleasant side effects, including sickness, headaches, and high blood pressure.

Weider Prime claims to have a premium testosterone support formula, but our review found it to be average at best. It’s cheap compared to stronger test boosters, and if you can handle the high ashwagandha dose, it certainly has some energy and mood boosting ingredients to help you exercise harder, but where testosterone is concerned, the benefits are minimal. So overall, we don’t recommend Weider Prime, and instead, our advice is to buy Testofuel or anything else from our best testosterone boosters for men list.
