Recovery
Epsom salt receives an Average overall score due to weak scientific backing for recovery claims despite high safety and quality. Effectiveness is low (25/100) as major sources like Examine.com highlight no robust evidence for transdermal magnesium absorption benefiting muscle soreness; benefits are likely from hydrostatic pressure and heat in baths, not MgSO4 (typical dose 300-600g/bath, but absorbed ~10-20mg per biased study). Small trials (e.g., flotation RCT n=24, pain reduction p<0.05; Counc
Epsom salt baths offer safe, affordable relaxation potentially aiding perceived recovery via warmth and buoyancy, but lack strong evidence for magnesium-driven muscle benefits. Suitable for general wellness, not as a proven recovery tool. Opt for USP-grade and compare to plain hot baths for similar effects at zero cost.
