Astaxanthin is a naturally occurring carotenoid pigment found in certain algae and seafood, widely recognized for its potent antioxidant properties. Some scientific studies have explored its role in supporting muscle health, particularly concerning muscle endurance, recovery, and the reduction of exercise-induced oxidative stress. A few small human clinical trials and animal studies suggest that astaxanthin supplementation might improve muscle performance, reduce muscle fatigue, and enhance recovery after exercise, likely due to its ability to counteract oxidative damage during physical activity. For instance, several double-blind, placebo-controlled trials in athletes and older adults have observed modest improvements in muscle endurance and decreased markers of muscle damage following astaxanthin supplementation (typically at doses of 4–12 mg daily over several weeks). However, evidence directly linking astaxanthin supplementation to improvement in muscle tone—specifically addressing the lack thereof, as in hypotonia or age-related muscle atrophy—is limited and largely indirect. Most available research focuses on performance and recovery rather than structural changes in muscle tone. While antioxidant support might indirectly benefit muscle function, there is insufficient high-quality evidence to recommend astaxanthin as a definitive treatment for lack of muscle tone. Further well-designed human studies are needed to confirm these potential benefits.
