B-Complex vitamins are essential for the formation of red blood cells, metabolism, nervous system function, to promote normal growth, and metabolism of nutrients and proteins. These vitamins are easily lost in refining and cooking; they can also be washed from the body by coffee, tea, alcohol and heavy perspiration.

Physically stressful conditions can also deplete the body of B vitamins. B-vitamins are also vital for good digestive function and enzyme reactions that control energy, circulation, hormones and overall health. Their actions are interdependent; so for greatest efficiency the complex should be taken together.

The vitamins in Nature's Sunshine's B-complex are yeast free, combined in a unique base of acerola, inositol, lemon bioflavonoids, PABA, rose hips, rutin and wheat germ. This provides additional nutritive support for nervous, circulatory and immune systems.
