The laboratory is standardised by SGS, the yearly production capacity is 3,000 tonnes, which guarantees 98% purity levels, zero pesticide residues and batch traceability. Our competitive edge is the vertical integration from raw material cultivation at our three planting bases to the final product delivery, which ensures you cost-effective premium grade sterols with stable supply chain security.

Product Introduction

Stigmasterol is a naturally occurring phytosterol chemical present in plants, which has been scientifically categorised as a phytosterol compound mainly obtained from soybean oil, rapeseed and Calabar bean sources using improved chromatographic separation techniques. White crystalline powder, with remarkable chemical stability and lipophilic qualities. Ideal active ingredient for cardiovascular health formulations and anti-inflammatory applications. The molecule is structurally similar to cholesterol, allowing it to competitively limit intestinal cholesterol absorption and provide effective antioxidant protection to cellular membranes.

Third-Party Test Report

Independent Laboratory Verification: Each batch of our stigmasterol undergoes extensive analysis by internationally authorised third-party laboratories such as SGS and Eurofins to guarantee total transparency and adherence to regulations.

Pesticide Residue Analysis: Multi-residue screening for over 500 chemicals indicate non-detectable levels (less than 0.01 ppm) for all pesticides tested, in compliance with both EU regulation 396/2005 and USDA organic requirements.

Products Specification

Stigmasterol Powder Advantages

Improved Bioavailability Profile: Micronised processing reduces particle size to optimise intestinal absorption rates, resulting in a 40% greater plasma concentration in pharmacokinetic testing compared to conventional grade goods.

Unique Chemical Stability: Our proprietary nitrogen-atmosphere Packaging and moisture control techniques keep the potency at 36 months in ambient storage, avoiding the degradation problems typically seen with unsaturated phytosterols.

Clean Label Certified: Certified organic, non-GMO, vegan-friendly and free of all synthetic solvents, it meets the highest clean label standards for premium supplement companies in Europe and North America.

Stigmasterol Powder Application

Cardiovascular Health Supplements: Our ingredient is available in softgels/tablets at 200-400mg daily doses for cholesterol control. It has been shown in clinical studies to reduce LDL via competitive inhibition of intestinal NPC1L1 transporters. It is often paired with Coenzyme Q10 or Omega-3s.

Women’s Health & Hormone Balance: Used in menopausal support formulas for its phytoestrogenic qualities. Provides mild hormonal modulation without the safety problems of synthetic HRT. Typical dosages are 300-600mg per day.

Sports Nutrition Recovery Products: Included in post-workout supplements that utilise powerful anti-inflammatory effects by blocking the COX-2 pathway to speed up muscle recovery and reduce exercise-induced oxidative stress in protein powder formulations.

Production Process

Step 1 – Raw Material Selection and Preparation: We source premium non-GMO soybeans from our certified organic planting bases, subjecting incoming materials to moisture content verification and foreign matter removal through precision cleaning equipment, resulting in standardized feedstock ready for extraction.

Step 2 – Extraction and Concentration of the Solvent: Soxhlet extraction of the cleaned material with ethanol pharmaceutical grade under controlled temperature conditions and rotary evaporation of the crude mixture of phytosterols to concentrate the extract to obtain the initial extract containing 40-50% of total sterol.

Step 3 – Saponification and Neutralisation: The concentrated extract is treated with potassium hydroxide solution at 80°C to saponify triglycerides and esters, then neutralised with hydrochloric acid to pH 7.0, yielding isolated unsaponifiable materials enriched in target sterols.

Step 4 – Chromatographic Purification: The unsaponifiable fraction is chromatographed on a silica gel column using gradient elution techniques, allowing the separation of Stigmasterol Powder from beta-sitosterol and campesterol, and obtaining fractions with a purity of >95% target compound.

Step 5 – Recrystallisation and Drying: Purified fractions are recrystallised in ethanol-water combinations with regulated cooling rates, and then vacuum dried at 40°C to eliminate residual solvents, yielding pharmaceutical-grade crystalline powder that meets USP residual solvent limitations.

Step 6 – Micronization and Quality Control: The crystalline material is jet milled to an 80-mesh particle size distribution under a nitrogen atmosphere and then undergoes a full HPLC assay, heavy metal screen and microbiological testing prior to being nitrogen flushed and bagged in pharmaceutical grade aluminium bags.

FAQ

Q: What is the suggested dosage for cardiovascular applications?

A: Clinical study doses are usually 200-400mg/day. However, consumer recommendations should be combined with guidance from experienced health professionals and formulation guidelines unique to your target market legislation.

Q: Can stigmasterol be combined with prescription statin medications?

A: Generally recognised as safe, we urge recommending your clients to seek healthcare providers before taking supplements with prescription medications due to possible additive lipid lowering effects.

Q: What’s the solubility profile for beverage applications?

A: Stigmasterol is not very soluble in water, but is very soluble in lipids. For beverage applications we suggest using our micronised grade with emulsification equipment or our custom nano-emulsion creation services.
