NOW Foods 5-HTP 100mg 60 Veg Capsules

NOW® 5-HTP provides 100 mg of 5-hydroxytryptophan (5-HTP) in every easy-to-take vegetarian capsule, naturally extracted from the seeds of the African plant Griffonia simplicifolia. 5-HTP is a compound your body produces from the essential amino acid tryptophan, and it sits just one step away from serotonin — a neurotransmitter that plays a central role in mood, relaxation and healthy sleep cycles.* Because it is the direct metabolic precursor to serotonin, supplementing with 5-HTP is a convenient way to support your body's own serotonin pathway. NOW® 5-HTP is a clean, focused formula with no unnecessary fillers, giving you a straightforward daily option for supporting a calm, positive and balanced state of mind.*

About the key ingredients

• 5-HTP (5-Hydroxytryptophan, from Griffonia simplicifolia seed) – 100 mg: A naturally sourced compound that is the direct precursor the body uses to make serotonin, the neurotransmitter associated with a positive mood, relaxation and healthy sleep.* Sourced from the seeds of Griffonia simplicifolia, a West African plant traditionally used for its naturally occurring 5-HTP content.
• Rice Flour: A gentle, plant-based flow agent that helps fill the capsule consistently — no synthetic bulking agents.
• Hypromellose (vegetarian capsule): A plant-derived cellulose capsule shell, making this product suitable for vegetarians and vegans.

Who it's for

NOW® 5-HTP is a good fit for adults who want gentle, natural support for a positive and balanced mood, especially during periods of everyday stress, seasonal changes, or busy schedules that leave you feeling mentally drained.* It may also appeal to those who are looking to support healthy, restful sleep patterns as part of a wind-down routine, since serotonin is a precursor to the body's sleep hormone melatonin.* Because it is vegetarian, Non-GMO and free from common allergens, it suits a wide range of dietary preferences. If you already eat a balanced diet but feel you need extra day-to-day support for calm and emotional balance, 5-HTP is a simple, single-ingredient option to consider.*

Frequently asked questions

What exactly is 5-HTP and where does it come from?
5-HTP (5-hydroxytryptophan) is a compound the body naturally makes from the amino acid tryptophan on its way to producing serotonin. NOW's 5-HTP is not synthetic — it is extracted from the seeds of Griffonia simplicifolia, a plant native to West Africa that naturally contains high levels of 5-HTP.*

How and when should I take it?
A common approach is to take one capsule one to two times daily. Many people prefer to take it with food to minimize the chance of mild stomach upset, and some take a dose in the evening to support relaxation before bed. Follow the directions on the label or the guidance of your healthcare provider.*

How is 5-HTP different from tryptophan or melatonin?
Tryptophan is the amino acid your body converts first into 5-HTP, and then into serotonin; 5-HTP skips the first step and is closer to serotonin in the pathway. Melatonin is made further downstream from serotonin and is used more specifically for sleep timing. 5-HTP is chosen when the goal is broad support for a positive, balanced mood.*

Is it vegetarian and free of common allergens?
Yes — it uses a plant-based vegetarian capsule and is not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients, making it suitable for most dietary preferences.

Cautions & interactions

Talk to your doctor before taking 5-HTP if you are currently using prescription medications — especially antidepressants (such as SSRIs, SNRIs or MAO inhibitors) or any other medication that affects serotonin — because combining them may not be appropriate. For the same reason, avoid taking 5-HTP alongside other mood- or serotonin-related supplements (such as St. John's Wort, SAMe, L-tryptophan or high-dose L-theanine) unless your healthcare provider advises it. 5-HTP may cause drowsiness, so use caution before driving or operating machinery and avoid combining it with alcohol or sedatives. It is not recommended for women who are pregnant or nursing, and should be kept out of reach of children.
