Micronutrients & recovery
Supplementation with antioxidant vitamins (E, C, beta-carotene) fails to provide cardiovascular protection and may increase mortality or fatal CHD risk in large clinical trials.
Do not rely on high-dose antioxidant supplements (Vitamins E, C, Beta-Carotene) to prevent heart disease. Large clinical trials show they offer no benefit and may increase mortality risk. Focus on obtaining antioxidants from whole foods like fruits, vegetables, and whole grains instead.

A total of 22 trials (n = 134,590 subjects)... a majority of the results (14 trials) have been disappointing failing to demonstrate any significant benefit with vitamin C, E, and β-carotene supplementation. Furthermore, within five trials, such antioxidant supplementation was associated with increased all-cause mortality and two have shown higher risk of fatal CHD (ATBC and CARET) [79,96].
Why this rating
Based on massive pooled data from 22 trials involving over 134,000 subjects, showing consistent lack of benefit or harm.
