Delivery Options


5-HTP is the shortened name for L-5 hydroxytryptophan. This is a compound that our body synthesises from the amino acid tryptophan, which is found in seeds, eggs, salmon and turkey, and is used to make the neurotransmitter serotonin.

5-HTP supplements are usually made with the seeds of the African shrub ‘Griffonia simplicifolia’.

These rapid-release capsules contain 50mg of 5-HTP, 5mg of niacin and 5mg of vitamin B6. Niacin and vitamin B6 both contribute to normal energy yielding metabolism.

They are 100% vegan-friendly 5-HTP supplements, which is useful as natural sources of tryptophan tend to come from animal products.

  • A 5-HTP supplement
  • Rapid-release bioactive formula
  • Suitable for vegans and vegetarians
