1000mg per Daily Serving (12:1 Extract, Withanolides 5%)

Used and trusted for millenia in Ayurvedia, ashwagandha is a potent adaptogenic herb. The patented KSM-66® form of the herb is a standardised full-spectrum extract that has been evaluated in 22 Gold Standard human clinical trials.

Stress & Anxiety: This incredible adaptogen (especially the KSM-66® form) has been clinically shown in double blind trials to significantly reduce measured cortisol levels (the stress hormone) and perceived feelings of stress [1],[2].

Testosterone: A multitude of studies have reported ashwagandha's ability to significantly raise serum testoesterone levels [3],[4].

Sleep: Sleep, stress and testosterone levels are all intimately linked. KSM-66® Ashwagandha has been shown to improve the quality of our sleep and has also been suggested to help people with insomnia management [5],[6].

Muscle & Strength: When combined with resistance training, KSM-66® Ashwagandha has been associated with significantly improved muscle mass & strength [7].

Cognition: It has also been suggested that it protects against neurodegenerative diseases amongst other benefits [8].

500mg per Daily Serving (10:1 Standardised Shilajit Extract)

Shilajit is a naturally-occuring mineral pitch formed over centuries by the natural decomposition of plant matter in the Himalayan & Altai mountain ranges. We use a standardised 10% powedered shilajit extract.

Energy & Respiration: Shilajit is best known for its ability to improve energy, increase stamina & reduce feelings of fatigue. It can increase the production of ATP (the energy transport molecule) in the body and the amount of oxygen delivered to our cells [9].

Male sexual health: Recent studies have shown that purified (powdered) shilajit can significantly improve male sperm count and spermatogenic activity when taken at a dose of 500mg/day [10].

Testosterone: A double blind trial showed significant increases in total testosterone, free testosterone & dehydroepiandrosterone (DHEAS) compared with a placebo in healthy men aged 45-55 [11].

Cognitive Health: Well documented in its potential to support cognitive health, shilajit has been purported to even prevent the development of neurodegenerative diseases such as Alzheimer's [12,13].

25mg Elemental Zinc per Daily Serving (as Zinc Bisglycinate)

A well known and vital mineral for a myriad of bodily functions, we use Zinc Bisglycinate as it is a highly-bioavailable form of zinc that is easy on the stomach.

Testosterone: Zinc is the most well researched mineral with regards to supporting healthy testosterone levels and there are a multitude of studies showing its ability to support optimal testosterone levels in men [14],[15],[16].

Male fertility: Zinc is absolutely pivotal to our fertility as men. Zinc levels are highly correlated with sperm count and quality [17].

Immune system: Playing a core role in the function of the immune system, zinc deficiency puts you at a far greater susceptibility to falling ill from pathogens [18].

It is estimated that approximately 20% of the world's population is at risk of being zinc deficient [19].

300mg Elemental Magnesium per Daily Serving (as Magnesium Glycinate)

Magnesium is an essential mineral used as a co-factor in over 300 enzymatic reactions in the body. We use the highly-bioavailable form, Magnesium Glycinate, in meaningful quantities - many magnesium supplements do not!

Muscle and nerve function: Magnesium is one of the most researched minerals when it comes to dietary nutrition, especially with regards to improving and supporting muscle and nerve function [20]. A double-blind clinical study concluded that significant gains in strength and muscle size relative to a placebo group were achieved with daily magnesium supplementation [21].

Sleep: Both magnesium & glycine have been shown to have a positive effect on sleep quality [22],[23]. We use magnesium glycinate for this reason and the fact that it is a highly bioavailable form and very easy on the stomach.

7.5mg Elemental Boron per Daily Serving (as Disodium Tetraborate)

Boron is an often overlooked trace mineral that has been shown to beneficially impact a myriad of biological health markers including hormonal health.

Testosterone: One study showed that supplementing 6mg of Boron a day for a week increased free testosterone levels by 25% [24]. Another study showed significant increases in free testosterone from boron supplementation as well as a reduction in inflammatory biomarkers [25].

150mcg Vitamin K2 per Daily Serving (as Menaquinone-7)

Vitamin K2 is a vital but sorely undervalued vitamin for our cardiovascular and bone health. Vitamin K2 (and specifically MK-7) is better absorbed than Vitamin K1 into our bones.

Bone & Heart Health: Vitamin K2 is an extremely important nutrient that works synergistically with testosterone-supporting Vitamin D3 to help prevent heart disease (through it's arterial-plaque-inhibiting effects [26]), as well as helping to maintain healthy bone density & mass [27].

4000IU Vitamin D3 per Daily Serving (as Cholecalciferol)

Known as the sunshine vitamin, Vitamin D3 is severely under-dosed in many products - our dose of D3 is at the Safe Upper Limit for daily intake as advised by the UK government.

Immunity: Well documented with its positive effects on the immune system [28], maintaining proper vitamin D3 levels is vital especially if you live somewhere like the sunny UK...

Bone Health: Vitamin D increases the metabolism of calcium in the intestines and as a result more calcium in absorbed by the body [29].

Testosterone: Vitamin D3 is the most important of the two vitamin D variants and was shown in a randomised controlled trial to significantly raise testosterone levels by as much as 30% at a dose of 3332IU/day in men with low testosterone [30].

It is estimated that 1 billion people are vitamin D deficient worldwide [31].
