Natural /Herbal sexual health supplements – a misnomer?

Many products advertised as herbal supplements for male sexual health are adulterated with prescription pharmaceuticals in undisclosed amounts. The dietary supplements are categorised as ‘nutraceuticals’ which do not fall under the regulatory jurisdiction of the FDA. So the consumers have few resources to verify the efficacy and safety of such supplements. Commonly used drugs for adulteration are:

  • Sildenafil which is commonly known by the trade name “Viagra”
  • Non FDA approved analogs of the above drug have also been found

Herbal / Natural / Ayurvedic Supplements for Sexual Health:

Red ginseng(panax ginseng /korean ginseng)

It is the most common ingredient among supplements for sexual health. It acts by increasing production of nitric oxide which causes dilatation of blood vessels which in turn helps in erection due to increased blood flow to the penis. Studies show significant improvement in erectile dysfunction but not yet approved as first line therapy. Side effects observed were:

  • Hypoglycaemia(hence to be used with caution in diabetics)
  • Headaches/insomnia
  • Gastric upset/constipation
  • Rash

Trace minerals found in sexual health supplements:

Trace minerals are found in most supplements in quantities beyond their recommended daily intake values. Following are the minerals commonly found in supplements:

  • Zinc – studies show that zinc deficiency leads to decreased testosterone production but there is no evidence that zinc supplementation in normal individuals causes increased testosterone production /improved sexual performance.
  • Magnesium – No studies show association of magnesium supplementation with improved sexual function.
  • Selenium – No studies show improvement in sexual health with selenium supplementation.

Vitamin supplementation :

B vitamins are essential for healthy metabolism. Deficiency in one or more of these can result in hyperlipidemia, hyperhomocystenemia and degenerative neuropathy which may be associated with sexual dysfunction. Hence replenishing B vitamins may be helpful in sexual dysfunction symptoms.

  • Vitamin B6 regulates homocysteine levels in the body. High levels of homocysteine have been associated with decreased levels of nitric oxide and poor erectile function.Hence vitamin B6 supplements may be useful.
  • Vitamin B12 supplementation in deficient individuals may improve sexual function by improving psychological aspects such as mood ,arousal,libido and energy.

Steroid in supplements:

  • Dehydroepiandrosterone(DHEA)

It is a steroid which gets converted to sex hormones testosterone and estrogen in the body. When used for improving sexual health it is not known to cause drastic alterations in hormone levels. Its efficacy in treating ED is yet to be proven.

Other ingredients:

  • L-arginine

It is a precursor for nitric oxide which helps in increasing blood flow to the penis . Studies have shown promising results for its use in erectile dysfunction.Low oral absorption limits its use.L-citrulline has been tried in its place owing to better oral absorption.

  • L-incarnadine

It is an amino acid derivative which causes blood vessels of the penis to dilate by augmenting prostaglandin synthesis. Few studies suggest its efficacy in treating erectile dysfunction when combined with other drugs.

  • Antioxidants

Oxidation stress plays a role in ED. Hence antioxidants like lycopene, vitamin E are known to be helpful in erectile dysfunction.
