Htp Powder

High-Purity 5-HTP Powder for Dietary Supplements & Functional Food Manufacturing

Avans NutriHealth Co., Ltd. provides pharmaceutical grade Htp Powder (5-Hydroxytryptophan) with ≥98% purity by HPLC from Griffonia simplicifolia seeds. Our product is a direct precursor to serotonin, bypassing the rate limiting tryptophan hydroxylase enzyme, with 3-5x better bioavailability than ordinary L-tryptophan. Our product is manufactured under ISO, HACCP and FSSC22000 certifications, is ‘Peak X Free’ compliant and has a bulk density of 0.45–0.65 g/mL making it ideal for encapsulation. Contains ≤1.0% moisture content and 36-month shelf life for batch-to-batch consistency in mood support, sleep aid and weight management formulations.

What Makes Our 5-HTP Powder the Preferred Choice for Manufacturers?

Our product solves three key formulation difficulties you have. First, it delivers standardised potency with 99%+ assay consistency, a far cry from the batch variability of raw plant extracts. Second, the particle size specification (100% pass 80 mesh) ensures homogenous mixing without segregation during high speed tablet compression.

Third, our rigorous contaminant control procedure guarantees that 'Peak X' impurity levels are undetectable, fulfilling FDA and EFSA safety limits. Why this matters: Not only does regulatory compliance protect your brand, but it also speeds up product approval timelines.

The material's slight solubility in water and complete solubility in alcohol leaves room for different delivery formats. The powder can be integrated into existing production lines, whether you are developing capsules, functional drinks or sublingual tablets.

Technical Specifications & Quality Parameters

Application Scenarios for Maximum Market Impact

Formulas for Mood and Cognitive Support

Customers want clean-label alternatives to synthetic antidepressants. Htp Powder is well suited to magnesium and B-vitamins in capsule form and is stable on storage. Its silicon dioxide compatibility prevents clumping in humid conditions.

Sleep Aids Products

Our powder is not degraded in acidic environments when mixed with melatonin and GABA. This stability is good for optimising the REM sleep cycle, an important differentiator for premium sleep aids. Thermal stability up to 270°C enables the co-processing with other heat sensitive substances.

Appetite Control & Weight Loss

It survives the extrusion temperatures of meal replacement bars or shakes and retains bioactivity. It works by raising serotonin levels, which curbs the desire for carbohydrates and promotes a feeling of fullness—key mechanisms for weight control products that focus on metabolic wellness.

Why Avans NutriHealth Stands Behind Every Batch?

We are an integrated group with its own production facilities in Qingdao, guaranteeing total transparency in the supply chain from raw material procurement to final packaging. Our R&D team is constantly keeping an eye on extraction procedures to eliminate leftover solvents and still keep the integrity of active compounds.

You are protected by strict in-process controls that ensure each batch of production is tested for heavy metals (Pb ≤3ppm, As ≤2ppm), microbial load (Total Plate Count <1,000 CFU/g) and pesticide residues. These parameters are not only numbers, they are your risk mitigation and consumer safety assurance.

Our technical support staff can help with formulation development, recommendations to improve solubility and stability testing data. We recognise that your product’s success depends on the consistent performance of raw materials from batch to batch.

Quality Assurance & Regulatory Compliance

Each shipment is accompanied by a Certificate of Analysis (COA) with HPLC chromatograms, moisture analysis and microbiological test findings. We also hold the FSSC22000 food safety certification, which confirms our compliance with international standards on allergen control and traceability.

The HALAL certification allows you to tap into markets with religious dietary restrictions. Our USDA Organic certification helps your organic product lines deliver on clean-label promises without the hassle of reformulation.

We have complete documentation trails for regulatory audits, including extraction process validation and stability study reports. This documentation package speeds your time to market by streamlining regulatory submissions.

FAQ

Q: Are 5-HTP and L-Tryptophan formulated differently?

A: 5-HTP crosses the blood brain barrier more efficiently and is converted directly to serotonin without requiring enzymatic hydroxylation. This means that the beginning of effect is faster and fewer dosages are required in comparison to L-tryptophan supplements.

Q: What dosages should dietary supplements be taken in?

A: Typical formulas are between 50-300mg per serving however the actual amount will depend on what health claims you are making and your regulatory compliance. Our technical team can help you with formulation based on your product positioning.

Q: Can the powder be used in liquid formats?

A: It is mildly soluble in water, but its solubility can be improved by micronization or by the use of co-solvents such as glycerin. Stability testing of liquid formulations is recommended to ensure consistent potency throughout shelf life.

Q: How do producers store the powder to keep it potent?

A: Store in tightly closed containers below 25°C away from light and moisture. Proper storage conditions maintain the 36-month shelf life and prevent oxidation of the indole ring structure.
