Chlorophyll gives plants their green color. Supplements use it mainly for body odor control and skin health. Most products extract it from alfalfa or use chlorophyllin, a semi-synthetic form that dissolves more easily in water.
Liquid drops, capsules, and tablets are common. People reach for chlorophyll to freshen breath and steady skin complaints like acne or sun damage. The research backing those uses remains thin. Follow the label because dosing jumps around from one brand to the next.
Chlorophyll is safe for most. Chlorophyllin forms can make skin more sensitive to sunlight. Green stools or a green tongue show up sometimes and are harmless. Anyone pregnant or nursing should talk to a doctor before starting.
