The Claim
Oral astaxanthin supplementation at doses of 2-12 mg/day for 4-16 weeks significantly improves skin elasticity in middle-aged adults with age-related skin signs, based on pooled analysis of 6 randomized controlled trials showing a large effect size of 0.77 (95% CI: 0.19-1.35, p=0.009).
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking astaxanthin supplements (a natural red pigment found in salmon and shrimp) every day for 1 to 4 months can make your skin more stretchy and elastic if you're middle-aged and noticing early signs of skin aging.
