Micronutrients & recovery
Selenium supplementation (200 µg/day) reduces the risk of prostate cancer, particularly in individuals with low baseline selenium status.
If you are selenium deficient, supplementation with 200 µg/day of selenium (e.g., from yeast) may help reduce your risk of prostate cancer. However, if you already have high selenium levels, you should avoid high-dose supplementation due to potential risks like increased diabetes risk. Get your levels checked first.
The follow-up analyses from the NPC trial convincingly verified the chemopreventive potential of 200 µg Se-enriched yeast per day to decrease, e.g. prostate cancer risk especially for participants that resided in the lowest tertile of baseline Se concentrations at the beginning of the study [21].
Why this rating
Based on a large randomized controlled trial (NPC trial) with follow-up analyses, though the exact mechanism remains unclear.
