What is 5-HTP?

5-Hydroxytryptophan (5-HTP) or Oxitriptan is a naturally occurring amino acid. It is also a chemical precursor that intermediates in the biosynthesis of serotonin.

5-HTP comes from tryptophan in your diet. Tryptophan is an essential amino acid.

The main purpose of Tryptophan is to balance nitrogen in your body. It also creates niacin. Niacin is extremely effective in creating serotonin.

There are mainly two types of tryptophan:

  1. L-tryptophan
  2. D-tryptophan

Both these types of tryptophan help in increasing serotonin production in your body. This is the main reason behind the popularity of 5-htp.

What does 5htp do to you?

Does 5 HTP make you lose weight?

So, basically, you eat less and naturally lose some weight and become more active and energetic.

It is your own brain that signals your body that you are full and you should not eat too much. So, it is a natural weight loss process.
