What Is Gamma Oryzanol Powder?

Gamma Oryzanol Powder is a combination of phytosterol ferulic acid esters mainly campesterol and beta-sitosterol and triterpene alcohols such as cycloartenol and 24-methylene cycloartanol. It is derived from the crude oil of rice bran (Oryza sativa).

It is a commonly utilised natural non-hormonal functional ingredient in pharmaceuticals, nutraceuticals and cosmetics. It works by blocking the absorption of cholesterol in the digestive tract and controlling the hypothalamus to stabilise the autonomic nervous system.

Third-Party Test Reports

We examine every batch of our rice bran extract in-house and through such authorised third-party laboratories as SGS and Eurofins. Testing includes the following areas:

· Assay purity: ≥98% (HPLC and UV-VIS)

· Residual solvents: Hexane < 290 ppm (USP <467> Compliant)

· Heavy metals: total < 10 ppm; lead < 1 ppm; arsenic < 1 ppm

• Pesticide residues: Tested as per international standard

· Microbiological safety: tested before each shipment

Third party reports available on request for each production batch.

Gamma Oryzanol Powder Advantages

High purity and composition confirmed.In addition, the 98%+ purity grade guaranties the natural ratio of cycloartenol to 24-methylene cycloartanol ferulates that verifies its rice bran origin and rules out synthetic adulteration.

Greater thermal stability.It preserves structural integrity when processed up to ~140°C — better than Vitamin E in hot settings. This makes it excellent for softgels, tablets and heat-treated functional meals.

Natural UV protection spectrum.It is suitable for use in suncare and anti-aging cosmetic formulations because of its strong UV absorption at characteristic peaks of 231 nm, 291 nm and 315 nm therefore providing broad spectrum UV interception.

Higher lipophilicity than free Ferulic Acid.This is the esterified version of Ferulic Acid and is more stable in oil-based and lipid-carriers systems, making it more applicable to premium supplements and cosmetic formulations.

Gamma Oryzanol Powder Application

FormulationsUsed as an Active Pharmaceutical Ingredient (API) in OTC and prescription medications for menopausal syndrome, autonomic ataxia and dyslipidemia. Clinically beneficial at doses of 300-500 mg/day for lowering LDL and for alleviation of psychosomatic symptoms.

Nutrition for sport.Part of quality sports supplements to increase synthesis of growth hormone and endorphins, balance cortisol-testosterone ratio as well as fight weariness after exercise — without the regulatory hazards of synthetic pro-hormones.

Suncare & Functional Cosmetics.It is included to high-end anti-aging lotions and sunscreens as it inhibits tyrosinase (skin lightening) and prevents lipid peroxidation on the skin surface.

Functional foods and nutraceuticals.Included in softgels and pill supplements for cardiovascular health and menopause management. Note: Due to the hydrophobicity of the product, nano-emulsification or liposomal encapsulation is required for aqueous beverage applications.

FAQ

Q1: What is the daily dosage of the formulation?

A: Clinical research supports 300-500 mg/day for hyperlipidemia and menopausal symptoms. Calculate the capsule fill weight depending on your target dose per serving.

Q2: Can it be used for drinks based on water?

A: No. It is water-insoluble and hydrophobic. Functional beverage applications require nano-emulsification or liposomal encapsulation for steady dispersion.

Q3: How does it compare with free Ferulic Acid in products?

A: It is the esterified form of Ferulic Acid which offers better lipophilicity and thermal stability which is more compatible with oil based carriers and heat processed products.

Q4: Does it have gluten or allergies from the rice bran source?

A: High purity extraction (>98%) usually eliminates allergenic protein fragments. However, batch-specific ELISA testing is needed for a Gluten-Free claim to be compliant with FDA < 20 ppm criteria.

Q5: What storage needs should be avoided to minimise degradation?

A: Keep in tightly closed, light-resistant containers (e.g. aluminium foil bags or lined fibre drums) in a cold, dry environment at temperature below 25°C. Shelf life is 24 to 36 months under normal storage conditions.

Q6: What paperwork can Hongda supply to assist with import compliance?

A: COA, MSDS, third-party test reports (SGS/Eurofins), phytosanitary certificates, certification copies (cGMP, HALAL, KOSHER, etc.) for each shipment.
