Testosterone is an integral part of what it is to be a Man, and if you're low in testosterone it can be debilitating to your self confidence as well as your body.

We were asked in the store recently about testosterone booster supplements, so we thought we'd go further in depth about this popular category of supplements. 

 Man with low testosterone - Peak Supps Blogs


How do you know if you have low testosterone levels?

Some symptoms include: Low sex drive, Difficulty with maintaining an erection, Low semen volume, Hair Loss, Fatigue, Loss of Muscle Mass, Decreased Bone mass and Mood Changes. 

If you recognise a few of these symptoms, remember that it gets much more common as you age. Once you reach the age of 60 it becomes somewhat unavoidable without supplementation or medication. (In-fact recent research has shown that 1 in 4 of Men over 30 have clinically Low Testosterone, often without physical symptoms).

If you're below the age of 30, you're less likely to have low levels, but strenuous exercise and extended periods of stress of any kind can cause a large decrease in your natural testosterone reserves at any age. 

In this case, it doesn't hurt to keep your natural test levels maxed out with some select supplements.


That's why we've gathered a list of the best supplements that can actively improve test levels.


1) Zinc is an essential mineral involved in many chemical processes within the body.

Higher Zinc intake has been closely associated with higher testosterone levels by one study which concluded that 

"Zinc may play an important role in modulating serum testosterone levels in normal men."

They also found that restricting zinc intake from foods lowered testosterone levels in healthy men. As expected, Zinc supplements in Zinc deficient men also increased testosterone levels. 

Another study measured the effects of Zinc on infertile men trying for a baby with either low or normal testosterone levels.

The researchers found significant benefits for those with low T levels, including increased testosterone and sperm count. However, they found no additional benefit for men with normal levels, suggesting that Zinc helps with Test-Deficiency related infertility, whereas the second groups infertility was most likely caused by other factors.

After the test-deficient group consumed Zinc Supplements; 

"Nine (out of 22) wives became pregnant immediately after the trial, six within 3 months and three within 2 months of a second trial."

So, perhaps Zinc supplements won't necessarily boost your fertility beyond normal levels if you're already at normal T-level. (Phew?)


Yet another study (2) on Zinc Supplementation measured an improvement in stress and exhaustion related testosterone level reduction in Professional Wrestlers after an intense 4-week high intensity training Boot-Camp. 

They concluded that

"physiological doses of zinc administration may benefit performance."

Zinc therefore is a great choice for any Male, athlete or not. Especially for Professional Athletes and men over 35. 

The effects of Zinc is largely why the supplement "ZMA" has become so popular. Many chose to get their Zinc intake from ZMA as the added Magnesium boosts metabolism & muscle health. It also is proven to help manage sleep and promote deep sleep. B6 has some research backing it to claim that it may boost energy.

We stock both Peak Supps Zinc Supplements and Peak Supps ZMA Capsules at a competitive UK Price with Free Delivery. 


2) D-Aspartic Acid 

D-Aspartic Acid has been the subject of multiple studies, and it seems to have very results to Zinc, but works through a different bodily system. It is formed naturally in the Pituitary Gland and testes, and aids the creation and regulation of testosterone. 

Research has shown that D-Aspartic acid supplementation increases testosterone production as well as how efficiently it is transported through the blood stream. 

The main benefit (or problem depending on how you view it) of D-Aspartic Acid is it's incredible power to improve sperm count in men with lower than average sperm production. One study found that 90 days of supplementation doubled sperm-count. (4)

D-aspartic acid seems to produce some strong swimmers. 

Much like Zinc, D-Aspartic acid may be most beneficial in people with low T-count levels or low sperm count. 

We stock D-Aspartic Acid  in Pure Powder form at Peak Supps. 


3. Vitamin D

 Monkey On the Beach

There's a reason some guys start acting like monkeys when the Sun comes out...

We're surprised that Vitamin D has strong effects on testosterone, even after writing a whole other blog on it's positive effects. 

Vitamin D is a vitamin produced in the skin when exposed to sunlight... but not many know that it functions as a steroid hormone in the body.

In Britain, especially in the winter months, we get very little exposure to sunlight, resulting in deficient levels of Vitamin D (6).

In a year-long study, 65 men were split into 2 groups. Half of them took 3,300 IU (international units) of vitamin D every day. The supplemented group's vitamin D levels doubled and their testosterone levels increased by around 20% (9). Could this show a causal link between Vitamin D and Testosterone? 

We currently have a sale on Peak Supps Vitamin D Capsules from only £1.89 with Free UK Delivery. 

4. Alpha Test Boost
