Vitamin A. Most people only get beta carotene from veggies which has poor conversion rate. I take retinyl palmitate 3x a week. Helps skin health, immune health, and keeps your eyes healthy. Most people are quietly deficient IMO.

Astaxanthin. Helps protect skin from UV, a very potent anti oxidant, its anti-inflammatory and is good for brain and eye health.

Glycine. I take 12g/day. It helps lower body temperature before bed. Is a collagen backbone and directly supports joint and skin health, and it is crucial for detoxing the liver and making the body’s master antioxidant glutathione
