It's estimated that well over 80% of adult Americans do not consume the desired daily amount of magnesium.

How does magnesium help fight hair loss?

When taken orally, magnesium helps with protein synthesis. Our hair strands are made almost entirely of keratin, a type of protein. Better protein synthesis means healthier hair regrowth.

Beans, seeds, rice, seafood, dark leafy greens, and nuts are excellent sources of magnesium. Some of the calcium supplements also supply magnesium to aid in calcium absorption.

Excellent sources of magnesium include:

  • Avocados
