Definition: What is Astaxanthin?
Astaxanthin is a naturally occurring red carotenoid pigment best known for its origin in the microalga Haematococcus pluvialis. It is acclaimed in nutritional science for being one of nature’s most powerful antioxidants. Unlike beta-carotene or vitamin A, Astaxanthin cannot convert to retinol, making it exceptionally safe for supplementation.1
How Astaxanthin Works: The Science Behind the Antioxidant
Astaxanthin’s unique molecular structure allows it to integrate into cell and mitochondrial membranes where it can neutralize a wide range of free radicals and reactive oxygen species (ROS). Its conjugated double bonds and oxygenated rings give it the remarkable ability to:
- Quench singlet oxygen (a damaging type of ROS) far more efficiently than vitamin C, vitamin E, or beta-carotene
- Reduce lipid peroxidation and support mitochondrial health Astaxanthin can be up to 65 times more potent than vitamin C in antioxidant capacity, and exceeds vitamin E or beta-carotene multiple times over.1

| Vitamin C | 1.5 |
| Vitamin E | 3 |
| Beta-carotene | 7 |
Evidence-Based Health Benefits

Astaxanthin in Supplements—Why It Matters for Quality
Given its potency, natural Astaxanthin from Haematococcus pluvialis is the gold standard—it is more stable and effective than synthetic forms. In supplements, it’s often found in capsules or softgels; optimal clinical doses range from 2–12 mg per day, usually within lipid-rich carriers for best absorption.1

Focus: The scientific application of natural active ingredients such as Tongo Ali, Horny Goat Weed, and Maca to sexual health and metabolic regulation.
Core Focus:
Men: Use a combination of Tongo Ali (an energizing factor) + Maca (an energy reserve) to improve low energy and fluctuating libido.
Women: Use a combination of Horny Goat Weed (a gentle regulator) + Maca (a nutritional synergist) to alleviate low libido and hormonal imbalances.
Stressed/Middle-Aged Adults: This triple-ingredient synergy supports metabolism, physical strength, and intimacy.
Product Concept:
Based on traditional applications and modern research (e.g., Tongo Ali promotes testosterone-enhancing enzyme activity, and icariin provides gentle regulation), we preserve core active ingredients and eschew conceptual packaging—using natural ingredients to address specific needs.
Simply put: I'm a nutritionist who understands "herbal actives." I use scientifically proven ingredients like Tongo Ali, Epimedium, and Maca to help you make "sexual health" and "nutritional support" a daily routine.
