Niacin

Niacin not only aids general cardiovascular wellness but also supports microvascular health, helping to nourish sensitive eye tissues. Regular intake may help maintain healthy ocular blood flow, an important factor in sustaining vision clarity over time. For product comparison, Niacin should be checked by exact form, plant part or compound type, standardization, amount per serving, and whether it is listed as an active ingredient, other ingredient, or part of a blend. Useful database notes include what it is used for, where it occurs naturally or how it is commonly sourced, and what shoppers should verify on the Supplement Facts label.
