The Importance of Combining: B Vitamins
The key factor of the B vitamin family is their complex interdependence, which takes two main forms. First, some B vitamins require other B vitamins for synthesis or activation. An example would be the synthesis of vitamin B-3 from the amino acid tryptophan, which requires vitamin B-2.30 Vitamin B-2 is also needed to turn vitamin B-6 into its active form in the body.

Second, the potential downside of high dose B vitamins are offset by other B vitamins. A good example of this is the fact that niacin may actually elevate homocysteine levels if taken alone31 but not when combined in a B complex.* The ability of niacin to maintain normal cholesterol levels, combined with the ability of folic acid, vitamin B-6 and vitamin B-12 to modulate homocysteine levels, provides a better approach than using them separately to maintain cardiovascular health.*32 The body has little trouble getting rid of excess B vitamins because they are water-soluble, and thus B vitamins in general have almost no adverse side effects.

Nature's Life B Vitamins
The water-soluble B vitamins are crucial for health maintenance. Every system in the body is affected by them, especially if there is inadequate dietary intake.

Some of the more important functions of B-complex nutrients include maintaining healthy nerves, providing energy, metabolizing coenzymes, fats and proteins, and supporting the health of skin, eyes and hair.* Due to their inter-dependent relationships, B vitamins are best when supplemented together. Nature's Life has developed different B-complex formulas in both tablets and capsules to offer the greatest benefits. All products are supported by peer-reviewed, controlled, human research. In addition to our formulas, we offer the essential B vitamins as individual supplements to best meet your needs.
