Product Specification
What is the source of astaxanthin in Sheni Labs Astaxanthin? Natural astaxanthin esters from the microalgae Haematococcus pluvialis — not synthetic astaxanthin.
What is the dose per drop? 12 mg of natural astaxanthin per drop.
Is there an EU NRV? No. Astaxanthin is a carotenoid antioxidant with no established EU Nutrient Reference Value. The 12 mg dose corresponds to the upper range studied in published clinical trials on skin elasticity and UV-related oxidative stress.
What is the bottle size? 30 mL, approximately 800 servings.
Where is it manufactured? European Union.
What is the product format? Liquid drops.
Natural vs Synthetic Astaxanthin
What is the difference between natural and synthetic astaxanthin? Natural astaxanthin from Haematococcus pluvialis exists as esterified carotenoids, which are genuinely oil-soluble. Synthetic astaxanthin is the free (non-esterified) form and behaves differently in terms of solubility and stability. Most published clinical research on astaxanthin uses natural algae-derived astaxanthin. Sheni Labs uses only the natural form.
Clinical Evidence
What has clinical research shown about astaxanthin? Randomised controlled trials using 6–12 mg daily have demonstrated measurable improvements in skin elasticity, hydration, and UV-related oxidative stress markers over 8–12 weeks. This evidence base is for the natural algae-derived form specifically.
What about longevity claims? Laboratory studies in model organisms have linked astaxanthin to extended lifespan through effects on mitochondrial function. This research is promising but at an early stage — it should not be interpreted as proven human longevity evidence.
Usage
Recommended use? Adults: 1 drop daily, with a meal containing fat, unless otherwise advised by a healthcare professional.
Why take with food containing fat? Astaxanthin is a fat-soluble carotenoid. Its absorption is significantly enhanced when taken with dietary fat.
Is this suitable for children? Keep out of reach of young children. Consult a healthcare professional before giving to children.
