Vitamin C – Super Vitamin for Immunity, Testosterone & HGH

Does Vitamin C Increase HGH?

Vitamin C’s health benefits and needs in humans have long been understood. So does vitamin C increase HGH? Vitamin C HGH boosting properties are not well known but are there nonetheless. The minimum recommended daily amount can easily be consumed by a normal well balanced diet. To see the benefits associated with bodybuilding and HGH require additional supplementation.


About Vitamin C

Vitamin C, also known as ascorbic acid, is a micronutrient very important for health. It is found in food but can also be taken in supplement form.

A deficiency of vitamin C causes a disease called scurvy. This is why it is on the World Health Organisations Model List of Essential Medicines (1).

It has a range of important functions which include:

  • Protect cells
  • Keep cells healthy
  • Maintain healthy
    • Skin
    • Blood vessels
    • Bones
    • Cartilage
  • Healing wounds
  • Immune system functioning

Adults need 40mg a day which is easily obtained through diet and found in foods such as:

  • Citrus fruits
  • Broccoli
  • Brussel sprouts
  • Strawberries
  • Spinach


If you take a vitamin C supplement then do not exceed more than 2,000mg a day.

This is the upper tolerable where you are unlikely to hurt yourself. Vitamin C can have some unpleasant side effects if too much is taken:

  • Stomach pain
  • Diarrhoea
  • Flatulence
  • Red hot flashes

This tends to happen at a dose in excess of 1,000mg.

Vitamin C is used by bodybuilders for a few different reasons.

It helps recovery by assisting protein metabolism and it can help increase testosterone by lowering cortisol and stress.



Vitamin C HGH connection

One study (2)  of 108 men and women, found that peak stimulated HGH was positively associated with vitamin C.

These were increases at a basal HGH, overnight maximum HGH and mean HGH secretion.

They conclude that micronutrients like vitamin C are strongly and uniquely associated with stimulated and endogenous spontaneous HGH secretion.

It has been observed in the past that high doses of vitamin C can accelerate weight loss but without obvious cause.

The answer may be in the HGH boost seen in this study. Standard doses to achieve this boost are typically 500-2,000mg.

The Verdict

Vitamin C is one of the best known micronutrients and supplements in the world.

It seems to be able to push up HGH levels at higher doses – 500-2,000mg.

This is a well dosed standard vitamin C product:
