Micronutrients & recovery
Selenium's biological activity is primarily mediated through its incorporation into selenoproteins (containing selenocysteine), which support antioxidant defense systems, thyroid hormone metabolism, and neuroprotection.
Selenium works by forming selenoproteins. Ensuring adequate intake (55 µg/day) allows your body to produce these proteins, which protect cells from oxidative stress and support thyroid and nervous system health.
GoodSupportsHIGH confidence
Se plays a substantial role in the functioning of the human organism. It is incorporated into selenoproteins, thus supporting antioxidant defense systems. Selenoproteins participate in the metabolism of thyroid hormones, control reproductive functions and exert neuroprotective effects.
Why this rating
Well-established biochemical pathway described in detail, including biosynthesis of selenocysteine.
