- Product Description
Premium Natural Astaxanthin Powder | 5% Potency for Nutraceuticals & Supplements
Science-backed 100% Pure Antioxidant Immune Support and Anti-Aging Formulas
Our natural astaxanthin powder is of exceptional quality, making it an ideal choice for high-performance nutritional supplements. Organic astaxanthin powder supplied by Shaanxi Hongda possesses a unique amphiphilic molecular chain (hydrophilic hydroxyl and ketone groups at both ends, and a long-chain lipophilic conjugated double bond in the middle). Like a strong "transmembrane rivet," it penetrates the inner and outer bilayers of the cell membrane, not only capturing free radicals in the extracellular fluid but also reaching deep into the mitochondria. Its singlet oxygen quenching ability is 550 times that of Vitamin E and 800 times that of Coenzyme Q10. For end consumers, it acts as a "dual-lightening engine for vision and skin," smoothing dull skin, blocking photoaging and erythema, and enhancing the vitality of the macula of the retina.
Hongda Phytochemistry's deep red powder is extracted from non-GMO Haematococcus pluvialis. Through supercritical CO2 low-temperature extraction and fully enclosed nitrogen protection, the astaxanthin molecules are in a naturally esterified passive protected state, ensuring no damage even during long-distance transportation. Nutritional companies that focus on efficacy will find that our ISO/FDA certified astaxanthin powder remains stable even after cold processing.

Why Our Natural Astaxanthin Powder Stands Out
- Astaxanthin 5%: Best at being absorbed by the body and fighting free radicals.
- 30 Years of Experience in Large-Scale Production: Shaanxi Hongda has been deeply involved in the field of phytochemical purification and micro-nano encapsulation for 30 years. It boasts a modern cGMP-standard production base with a building area of over 20,000 square meters, with an annual comprehensive extraction and microencapsulation throughput capacity of over 10,000 tons. Equipped with advanced supercritical ton-level continuous extraction lines and multi-stage spray freeze-drying microencapsulation production lines, it ensures a 98% overlap rate in absorbance, color, and particle size between different batches of bulk products.
- Haematococcus pluvialis microalgae that are grown in a way that is good for the environment and do not include GMOs.
- This product is high-quality according to ISO 9001, FDA-GMP, ECOCERT, Halal, and Kosher.
- Capsules, softgels, and powdered mixes that have been cold-processed keep stable.

Where to Use Natural Astaxanthin Powder
💊 Strong medicines and lotions battle free radicals and slow aging.
🏋️ Astanxanthin's healthy and strengthens muscles.
🧴 Recipes for Beauty: UV rays are blocked, keeping skin flexible.
🥤 Functional Foods: Fortified drinks and candy.

Customize your team's astaxanthin solution
1. Anti-photoaging soft capsules: Hongda 10% natural astaxanthin oil + high-purity reduced glutathione (GSH) + natural lycopene oil + free lutein. Utilizing astaxanthin's synergistic effect with glutathione to scavenge free radicals within cells and lycopene's UV protection in the dermis, this creates a top-tier oral sunscreen for brightening and whitening the skin.
2. Blue light blocking for retinal macular repair: Hongda nano-grade CWD astaxanthin microcapsule powder + esterified lutein + zeaxanthin + European blueberry extract (anthocyanins). Leveraging astaxanthin's unique pharmacological property of easily penetrating the blood-retinal barrier (BRB), this solution specifically replenishes pigment density in the macular region of the retina. The liquid form has a refreshing taste, no algae-like odor, and extremely high stability.
3. Post-exercise repair: Utilizing Hongda's instant-dissolving 2.5% Natural Astaxanthin Powder, combined with coenzyme Q10 and natural mitochondrial energy complex salts. Specifically designed for delayed onset muscle soreness (DOMS) experienced by advanced fitness enthusiasts after exercise, it utilizes astaxanthin's physical properties to protect the mitochondrial membrane of skeletal muscle, significantly shortening the recovery period from sports injuries.

Quality Assurance Process
1. Choosing a strain: algae that doesn't have any GMOs and grows in a controlled bioreactor.
2. Taking supercritical CO2 out keeps antioxidants safe.
3. Microencapsulation: inhibits movement and makes it easier for the body to use.
4. Batch Testing: Heavy metals, microorganisms, and strength are checked.
