★★★★★ "I won't go back to high street supplements. The difference in quality is something you can actually feel." Susie
5-HTP Capsules give you 5-hydroxytryptophan from griffonia seed with vitamin B6 as P5P, the active form your body uses alongside it. Each capsule provides 50mg of griffonia seed extract and 2.3mg of vitamin B6, taken once a day with food. One pot holds 90 capsules, which is a 90 day supply.
Benefits of taking 5-HTP
5-HTP is the compound your body makes from tryptophan on the way to serotonin, while vitamin B6 is the cofactor it uses for that conversion. The two are supplied together for that reason, at a low starting amount.
- Mood and thinking stay steady, because vitamin B6 supports normal psychological function.
- Nerves get the B6 they need to work properly.
- Serotonin production gets the step after tryptophan supplied directly.
Who benefits
5-HTP Capsules are most useful for:
- People who want a low starting amount of 5-HTP, at 50mg.
- Anyone who wants the active B6 included rather than taking it separately.
- Those who take it in the evening, when serotonin converts to melatonin overnight.
What is in it
Each capsule provides 50mg of griffonia seed extract standardised to 5-HTP, with 2.3mg of vitamin B6 as P5P, which is 164% of the daily reference value. The other ingredients are cellulose and the vegetable capsule shell. 5-hydroxytryptophan, oxitriptan and griffonia seed extract are other names for it.
How to take it
Take one capsule a day with food. For mood, the morning works well, while for sleep take it in the evening 30 to 60 minutes before bed.
Diet and allergens
The capsules are suitable for vegans and vegetarians. They are free from gluten, dairy and nuts.
Quality
The capsules are made in the UK in a GMP certified cleanroom facility accredited to ISO 9001 and ISO 14001. Every batch is traceable from raw material to finished product. Like every supplement Nutri Tailor stocks, they are practitioner grade and guaranteed additive free.
Common questions
What is the difference between 5-HTP and L-tryptophan?
L-tryptophan is the amino acid from food, which your body converts first to 5-HTP and then onward, with the first step the slow one. 5-HTP skips that step, so a smaller amount goes further, which is why it is taken at 50mg where tryptophan is taken at hundreds of milligrams.
How much 5-HTP should I take a day?
Take one capsule a day, which gives you 50mg of griffonia seed extract. It is a low starting amount.
When is the best time to take 5-HTP?
In the morning for mood, or 30 to 60 minutes before bed for sleep, so serotonin can convert to melatonin overnight.
Can I take it with other supplements?
Yes. It sits alongside Magnesium Bisglycinate (Glycinate) Capsules in the evening, which supports normal psychological function and is the form most often chosen for sleep.
Does 5-HTP have side effects?
Taking it with food keeps it easy on the stomach. If you take a prescribed antidepressant, speak to your GP before adding 5-HTP, because the two act on the same pathway.
Why is vitamin B6 included?
Your body uses vitamin B6 to convert 5-HTP to serotonin, so the P5P in the capsule supplies the cofactor for the next step.

Frequently asked questions
How does 5-Hydroxytryptophan (5-HTP) support mood?
5-Hydroxytryptophan (5-HTP) supports neurotransmitter production and emotional balance.
When should I take mood support?
Follow label directions for optimal timing.
Can I take this with prescription medications?
Consult your provider, especially if taking antidepressants.
How do nutrients affect mood?
B vitamins, omega-3s, magnesium, and amino acids are building blocks for neurotransmitters like serotonin and dopamine.
Why are the gut and mood often discussed together?
Most of the body's serotonin is made in the gut, which is why the two come up together. There is no authorised health claim for 5-HTP, so Nutri Tailor makes none.
5-HTP or L-tryptophan: what is the difference?
L-tryptophan is the amino acid from food; the body converts it first to 5-HTP and then onward, and the first step is the slow one and competes with other uses of tryptophan. 5-HTP skips that step, so a smaller dose goes further, which is why it is taken at 50 mg where tryptophan is taken at hundreds of milligrams. These capsules give 5-HTP from griffonia seed with P5P, the form of vitamin B6 the body uses in the next conversion. Neither should be combined with prescribed medicines that act on the same pathway without a GP's agreement.
Why capsules rather than tablets?
Tablets need binders, fillers and a coating to hold their shape. A capsule is a cellulose shell around the powder, so it carries no binders and breaks down quickly once swallowed.
