Frequently Asked Questions (FAQs)

1. Is there a natural form of 5-HTP?

The amino acid tryptophan, which the body uses to make 5-HTP, can be found in turkey, chicken, milk, potatoes, pumpkin, sunflower seeds, turnip and collard greens, and seaweed.

2. Who should not take 5-HTP?

Do not take 5-HTP if you're taking other medications that increase serotonin levels, such as antidepressants like SSRIs and MAO inhibitors. Use caution when taking carbidopa, a medication for Parkinson's disease. 5-HTP is not recommended for people with Down syndrome, as it has been linked to seizures.

3. Is 5-HTP vegan?

5-HTP is a precursor to a neurotransmitter called serotonin. Serotonin is known as promoting mental well-being. It is involved in mood, appetite, sleep, memory, and learning. Our 5-HTP 100 mg is derived from the seeds of the Griffonia simplicifolia plant, and is suitable for vegans and vegetarians.

4. Does 5-HTP permanently increase serotonin?

When infinitely high amounts of 5-HTP are administered, it is theoretically possible to achieve infinitely high levels of serotonin. One limiting factor is the availability of the enzyme L-aromatic amino acid decarboxylase (AAAD), which freely catalyzes the conversion of 5-HTP to serotonin.
