Progressive Labs Aller-B - 90 Caps

Aller-B is a high potency B complex in capsule form containing no allergy-provoking fillers and binders.

B-complex vitamins support nervous system function. The need for these essential vitamins increases during periods of mental or physical stress. All the B vitamins should be taken together. Since these vitamins are so closely interrelated in function, a lack of one or more can affect the body’s utilization of others.
