The Claim
Oral astaxanthin supplementation at doses of 2-12 mg per day for 4-16 weeks significantly improves skin moisture content in middle-aged adults with age-related skin signs, based on pooled analysis of 5 randomized controlled trials showing a moderate effect size of 0.53 (95% CI: 0.05-1.01, p=0.03).
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 pills (about 2-12 mg daily for 1-4 months) can help middle-aged people's skin stay more moisturized, according to research combining 5 different experiments.
