Griffonia Simplicifolia Capsules | Natural 5-HTP Supplement | OEM & ODM Manufacturing Support

Shaanxi Hongda Phytochemistry Co., Ltd. is a reliable manufacturer and supplier of Griffonia Simplicifolia Capsules, producing standardised 5-HTP capsules with purity levels ranging from 5% to 98% as verified by HPLC. Established in 2001, our 20,000㎡ site has 10+ advanced production lines and 100,000-level cleanrooms. We produce 3,000 tons of completely documented, multi-certified herbal capsules, and provide B2B buyers globally. Each batch is assayed by HPLC, screened for heavy metals, tested for pesticide residues and analysed for microbes — before shipping — to provide you a product you can confidently take to market.​​​​​​​

What Are Griffonia Simplicifolia Capsules?

This woody climbing bush is only found in West and Central Africa, mostly in Ghana and the Ivory Coast. The seeds have the most pure 5-Hydroxytryptophan (5-HTP) that can be bought in stores.

5-HTP that comes from Griffonia seed extract instead of synthetic tryptophan crosses directly between the blood and brain. It is a direct precursor of serotonin (5-HT), which controls food, mood, and the quality of sleep through the serotoninrgic pathway.

The Griffonia seed extract in our capsules is a standardised powder that is off-white to gray-white in colour, 95% through 80 mesh in particle size, and 0.45–0.65 g/ml in bulk density. This makes the flow even and makes sure that each pill has the right amount of medicine.

Third-Party Test Report

Each batch of our 5-HTP capsules is tested in our in-house laboratory (standardised to SGS) and confirmed by third-party organisations (SGS, Eurofins).

Testing includes:

· Potency: HPLC assay verifying no less than 98.0% on the 5-HTP dry basis (high-purity grades)

· Contaminant screening: No “Peak X” (cytotoxic impurity associated with Eosinophilia-Myalgia Syndrome, EMS) detected

· Solvent residue: Food grade ethanol and water used in extraction; no Class 1 and 2 solvents

· Heavy metals (ICP-MS): Pb, As, Cd, Hg all <10 ppm total, in compliance with Proposition 65 and EU food safety requirements

· Microbiological, pesticide residues, moisture: Per batch testing prior to shipment

Test reports are available upon request.

Griffonia Simplicifolia Capsules Advantages

Chirality profile. Natural.Our pills contain botanical-extracted 5-HTP, not 5-HTP from fermentation. This preserves the natural L-form chirality and avoids the contamination danger of synthetic tryptophan methods.

Wide purity range for any budget.We offer 5-HTP standardisation from 5% to 98%, allowing you to create low cost products or high potency premium products without changing suppliers.

Particle engineering for mild encapsulation.The extract passes 80 mesh at 95%, has a bulk density of 0.45-0.65 g/ml and provides steady flow during high speed capsule filling eliminating capping, weight variation and manufacturing waste .

Ready for clean-label.Extraction is carried out using simply ethanol and water as solvents. No Class 1 or Class 2 solvents. This backs clean-label claims increasingly requested by US and European purchasers.

Griffonia Simplicifolia Capsules Application

Sleep support formulas: 5-HTP tablets assist regulate circadian rhythms by producing serotonin in combination with Melatonin and Magnesium Bisglycinate. Here, high oxidation stability is important and our encapsulation technique efficiently protects the active substance.

Weight management products: The 5-HTP in appetite suppressant mixes impacts satiety signalling via the serotonergic system. Our standardised powder is stable throughout heat processing steps applicable to food preparation.

Mood and nootropic stacks: Used in multi-stage release tablets with L-Theanine and Tyrosine. The flowability profile of the extract confirms the accurate compression of tablets at high speed without any lamination problems.

Production Process

Raw seed sourcing → clean and dry → ethanol-water extraction → filter and concentrate → spray dry → sieve (80 mesh) → HPLC standardisation check → blend to target 5-HTP percentage → capsule filling in 100,000 level cleanroom → in-process weight check → final QC inspection → Packaging and labelling → shipping with full documentation.

Each step is controlled under cGMP conditions. Each batch is traceable from raw material input to discharge of final capsules.
