Why you need it

Zinc is part of hundreds of enzymes and plays a role in cell division, protein synthesis, immune function, and wound healing. It's important for skin, hair, taste perception, and reproductive health.

Signs of deficiency

  • Frequent colds and slow wound healing.
  • Loss of appetite and reduced taste sensitivity.
  • Skin problems and hair loss.

How your body absorbs it best

Zinc from meat and seafood is absorbed better than from plant sources — phytates in grains and legumes bind to it. Soaking and sprouting beans and grains reduces phytate content.
