Magnesium glycinate is the most bioavailable form — it actually gets absorbed. Take it at night and you'll notice deeper sleep within a week. Also helps with muscle cramps and stress. One of my daily non-negotiables.

Collagen is the skin, hair, nail, and joint supplement everyone should be on. Add one scoop to your morning coffee or smoothie — completely flavorless. The difference in skin elasticity after 4 weeks is real.
