What exactly is 5-HTP Griffonia Seed Extract?
A defined compound extracted from Griffonia simplicifolia seed.
5-HTP is the shortened name for 5-hydroxytryptophan. This formula supplies the compound through a concentrated extract obtained from the seed of Griffonia simplicifolia.
The 99% figure identifies the declared 5-HTP specification of the Griffonia Seed Extract. This gives customers a defined compound percentage rather than only a general plant or seed-powder description.
Each capsule contains 300mg of the extract. Two capsules provide 600mg, representing 594mg of 5-HTP at the declared 99% specification.
The defined compound
5-HTP is the familiar abbreviation for 5-hydroxytryptophan and the compound identified by the 99% specification.
Customers may also see the name written as 5 HTP, 5-hydroxy-L-tryptophan or Griffonia 5-HTP.
The botanical source
Griffonia simplicifolia is the accepted botanical name for the plant used as the source of this seed extract.
The full ingredient wording identifies both the compound customers are buying and the named botanical seed source.
99% 5-HTP
The percentage identifies the declared 5-HTP content within the concentrated Griffonia Seed Extract.
Griffonia seed powder
A general seed-powder description identifies the botanical material but does not present the same 99% compound specification used in this formula.
Understanding the extract numbers
99% 5-HTP. 600mg of extract per serving.
The percentage and milligram figures describe two connected parts of the formula. The 99% figure identifies the declared 5-HTP content of the extract, while 600mg states the physical Griffonia Seed Extract amount supplied across two capsules.
Declared 5-HTP specification
5-HTP accounts for 99% of the stated Griffonia Seed Extract specification.
Within one 300mg capsule, this represents 297mg of 5-HTP.
Complete extract serving
Two capsules provide 600mg of Pure 5-HTP Griffonia Seed Extract.
At the declared 99% specification, the complete serving represents 594mg of 5-HTP.

Why choose these 5-HTP Griffonia Seed Extract capsules?
The 99% seed extract should lead the formula.
British shoppers buying 5-HTP capsules are paying for the defined Griffonia Seed Extract. Crown Supplements keeps the formula centred on the 99% extract and its named uptake ingredient instead of filling capsule space with materials added for bulk, binding or machinery convenience.
Defined compound identity
The formula identifies 5-hydroxytryptophan as the compound customers came to buy.
99% specification
The declared percentage gives the extract a precise compound specification.
Named seed source
Griffonia simplicifolia seed is identified within the ingredient description.
600mg serving
Two capsules provide 600mg of the defined Griffonia Seed Extract.
Named uptake ingredient
Pure Psyllium Husk Extract is identified directly as the stated uptake ingredient.
No production clutter
No fillers, binders or machine flow agents are added by Crown Supplements.
The Crown Supplements formula standard
Built around 5-HTP—not machinery convenience.
When botanical capsule formulas include fillers, binders, bulking materials or flow agents, part of the ingredient list is built around production rather than the Griffonia Seed Extract printed on the front.
They may help the machine. They are not the reason the customer buys the capsule.

Brilliant Items, work really well
Can’t fault these supplements the 5 htp is my favourite
Having dreams again really is something amazing. This product in combination with lions mane have greatly contributed to my brain health and relaxation. I feel at peace and I am humble, absolutely recommend it to anyone. I take one of these a day paired with lions mane mushroom capsules every night at dinner. Honestly it’s amazing!
Sleep was the reason I picked up 5 htp. I take it in the evening now and my nights feel a bit more settled, without feeling groggy the next morning
I have been taking 1-2 capsules per night for about 8 weeks now and have found it definitely takes the edge off my menopausal stress symptoms and I wake up in a much better mood. They always arrive promptly and I appreciate that the pack fits through the letterbox
It’s rare to find a UK supplement company that offers this level of quality and transparency. I’ve switched to Crown Supplements for all my organic supplements because their ingredients are always clean, non-GMO, and sustainably sourced. Their vegan capsules are a huge plus since I avoid gelatin based products
Picked up 5 htp because i wanted something simple for evenings. the capsules are small enough and easy to remember
Earlier in the day seems better for me with 5 htp. capsules are small, so one bottle should last a while
5 htp was easiest for me in the evening. the capsules are small and the bottle does not take up much room
Small capsules make 5 htp simple to take. i use it occasionally rather than every day
