Vitamin D is a fat-soluble nutrient and steroid hormone, which regulates more than 1,000 bodily functions.

The benefits of Vitamin D on testosterone production are
well evidenced.

Studies have shown that men with sufficient vitamin D levels have
significantly higher testosterone than those with low levels.

Studies have also shown that supplementing with Vitamin D can increase free and total testosterone up to 25%.

Vitamin D has been clinically proven to:

• Contributes to the normal function of the immune system.
• Contributes to the maintenance of normal bones.
• Helps maintain normal muscle function.

Bone loss, low testosterone, compromised immunity and reduction of sperm quality are
just a few results of vitamin D deficiency.

It's estimated that around 80% of the UK population have sub optimal
levels of Vitamin D.

Vitamin C (ascorbic acid), a powerful antioxidant and water-soluble vitamin.

This means that it dissolves in water and is delivered to the body’s tissues but is not well stored, so it must be taken daily through food or supplements It helps the body’s detoxification pathway.

It enhances liver function by promoting the production of detoxifying enzymes.

These enzymes assist in breaking down toxins and facilitating their elimination from the body including removing excess oestrogen.

It also plays a proven role in:

• Our endocrine health which controls hormone production, requires vital levels of this nutrient.
• Managing cortisol levels – Vitamin C is rapidly depleted during stress.
• Elevated cortisol levels inhibit testosterone production – thereby keeping levels optimal reduce this risk.
• Helps optimal functioning of the nervous and immune systems.
• Function of the immune system
• Protects DNA, proteins, and lipids from oxidative damage – vital in super-aging.

Our formulas are the only men’s hormonal health supplements that include all the B Vitamins.

The B-complex vitamins have dramatic mood-elevating effects — more so than almost any other nutrient.

The family helps the body and mind stay healthy, sharp, energetic, balanced, and they play a crucial role in the detoxification process.

The master controller of hormones - the endocrine system - needs the B
vitamins to assist in the production and metabolism of hormones and neurotransmitters.

These water-soluble nutrients cannot be stored by the body – needing daily intake.

Each plays an essential role and are co-factors for many other nutrients. Deficiency in one can impact the way the other’s work, which is why there are major benefits from including them together.

Thiamine plays a vital role in metabolism, helping the body break down and release energy from food. Thiamine also helps to metabolise glucose.

It’s also important in maintaining the health of the nervous system.

When you're deficient in vitamin B1, you might experience symptoms such as fatigue, muscle cramps, various pains, and a reduced tolerance to pain. Carbohydrate addiction can be a sign of being thiamine deficient.

Every single cell within your body requires vitamin Riboflavin and other B vitamins cannot perform their roles unless an ample amount of B2 is in the body.

Riboflavin is one of the essential nutrients needed in testosterone production.

One of the most crucial roles is its ability to inhibit testosterone 5 alpha-reductase.

This enzyme:

• Converts testosterone into DHT in the testicles and prostate.
• DHT is crucial for some functions in the male body.
  But needs regulation.
• Too much of it can lead to hair loss and other unwelcome health issues.

B3 is a natural human growth hormone booster that can lead to anabolic changes in building lean muscle mass and strength.
It helps regulate cholesterol levels, both good and bad, which indirectly improves testosterone levels.

Research has found that supplementation daily can:

• boost testosterone levels.
• reduce erectile dysfunction.
• lower lipid and cholesterol levels.
  
  

Leydig cells, cells in the testicles, take cholesterol and convert it to testosterone, making vitamin B3 a must have ingredient in our formulas.

B6 is clinically evidenced to regulates sex hormones. We can’t produce it ourselves, so it is essential we get this from other sources. The older we get the more B6 we require, making deficiency more likely.

It directly influences testosterone production by increased demand for androgens. When the body lacks B6, the brain increases oestrogen levels. This vitamin acts as a counterbalance for hormone regulation.

B6 also:

• Plays a major role in processing the protein, carbs, and fats you eat.
• It is involved in the autonomic processes of your nervous and immune systems.
• Helps with memory, cognitive functions, and energy levels,
  

Vitamin B9 is more commonly known by its synthetic supplemental form 'folic acid'.
It is crucial for proper brain function and plays an important role in mental and emotional health.

Folate is involved in:

• The synthesis of neurotransmitters like serotonin, dopamine, and noradrenaline.
• These neurotransmitters play a role in mood regulation and overall mental well-being.
• Works with vitamins B6 and B12 and other nutrients to control blood levels of the amino acid homocysteine.

It is common to have low levels of folic acid.

Chronically low folate levels can lead to mood disturbances, which may indirectly contribute to feelings of tiredness and fatigue.

Alcoholism, inflammatory bowel disease (IBD), and celiac disease can cause folic acid deficiency. Also, certain medications may lower levels of folic acid in the body.

Helps reduce tiredness and fatigue.

Vitamin B12 is a vital member of the B vitamin family, playing a pivotal role in various bodily functions, notably the formation of red blood cells. When there's a chronic shortage of vitamin B12 it can diminish the blood's ability to carry oxygen, leading to feelings of weariness and fatigue.

Biotin, plays a crucial role in our body and directly impacts our hormones:

It aids in proper endocrine function. A deficiency of biotin can lead to dysfunction in both the adrenal glands and the thyroid,It’s also required for healthy hair, skin and nails.

Pantothenic acid provides foundational support for both Phase I and Phase II detoxification. Vital for elimination of excess oestrogen and environmental toxins.

It is essential for testosterone production as the testes require B5 vitamin to help convert cholesterol to testosterone.

In addition:

• It plays an important role in the production of adrenal hormones.
• All the steroid hormones will be produced only with ample B5 in the system.
• It is involved in the production of neurotransmitters.
• Pantothenic acid is a stamina enhancer and prevents certain types of anaemia.

Deficiency can cause fatigue, headaches, nausea and tingling in the hands.

Magnesium is one of the most important minerals needed for life - involved in over 300 enzymatic processes in the body.

It has essential benefits on men’s hormonal health:

• It assists with managing SHBG molecules which bind the majority of testosterone in your body and make it inactive.
• It’s essential for the metabolism of nitric oxide, which is involved in the erection process.
• It boosts sleep quality which is vital for testosterone health as testosterone is replenished overnight – requiring good quantity and quality sleep.
• It promotes recovery from intense workouts, improves muscle health and lean body mass.
  
  Additional, clinically proven benefits include:
  
  
• Magnesium contributes to a reduction of tiredness and fatigue.
• Magnesium contributes to electrolyte balance.
• Magnesium contributes to normal functioning of the nervous system.
  
  Studies have shown that 50% of the population do not meet their daily requirement.
  

Important mineral that is crucial for male hormonal health.

It plays a key role in supporting the endocrine system and plays
a major role in testosterone production. 

Optimal zinc levels prompt Luteinizing hormone, which stimulates production of
testosterone in men.

Low levels are intrinsically linked to low testosterone levels and poor fertility.

Zinc has been clinically proven to:

• Support normal testosterone levels.
• Reduce tiredness and fatigue.
• Supports skin, hair and nails health.

Zinc deficiency affects over two billion people worldwide and ranks as the 11th major risk
around the globe in malnutrition.

L'Citrulline is another powerful amino acid that works in partnership with L-Arginine which is
why we included both in this formula.

It is regarded as a pro-erectile agent because it is a precursor of L arginine, which produces nitric oxide. In turn, nitric oxide uses the same pathway as Viagra.

Supplementation has been proven to increase blood flow without increasing blood pressure.

Additionally, it benefits cardiovascular health:

• Vasodilation - enabling blood vessels to expand.
• Increases blood flow and increases oxygenation.
• Reduces arterial stiffness.

All incredible benefits to supporting powerful pro aging and longevity
in men.

L-Arginine is an amino acid, that can help with erectile dysfunction
which can be a symptom of low testosterone.

It does this by boosting nitric oxide which helps blood flow.

Due to this action, it has many other health benefits including:

• Help to lower blood pressure.
• Assists wound repair.
• Support blood flow to your muscles by improve anaerobic
  capacity.
• It stimulates growth hormone.
• Boosts
  metabolism and decreases fat.

Grey Fox strategically uses the combination of L'Arginine and L'Citrulline as these two powerful amino acids work synergistically together to deliver the maximum benefits of nitric oxide
production.

Nettle is beneficial for male hormones. It works primarily to keep testosterone active in the body for longer.


As most of the testosterone in your body is bound - in particularly to SHBG (sex hormone binding globulin) molecules – it renders the male sex hormone biologically inactive.

Nettle root has been shown to be effective in men’s hormonal healthy by:

• Binding with SHBG, making more biologically active testosterone freely available to your system.
• Blocking the enzyme that makes DHT (dihydrotestosterone) that contributes to male pattern baldness.

Scientifically known as Withania somnifera, Ashwagandha is a popular herb with many benefits and is particularly renowned for reducing stress and is classified as an adaptogen.

It helps maintain stamina, feelings or energy and vitality and promote physical
& mental wellbeing.

In terms of testosterone and hormonal balance, Ashwagandha has shown promise in supporting testosterone levels.

Studies have shown that supplementing over 16 weeks can help men with:

• Increased Testosterone Production
• Increased DHEA(Master Hormone) production
• Increase the production of LH (Luteinizing Hormone) which triggers the production of testosterone

Reducing cortisol (stress hormone) also helps promote hormonal balance. It also has powerful relaxation properties and can help as a sleep aid.
