While chlorophyll and chlorophyllin certainly offer benefits, the nutrients in the liquid supplement are limited when compared to eating whole vegetables.
"If you eat a cup of spinach, you get roughly 24 mg of chlorophyll," says Grasso. This is roughly equivalent to a pipette (or half a teaspoon) of the liquid variety. "When you eat your greens, you get into not only your chlorophyll, but vitamins, minerals, antioxidants, and fiber," she explains.
For the extra nutrients and the lower price, Grasso says, "Yes, I choose vegetables." Adding a liquid chlorophyll supplement to your daily routine along with a balanced diet high in vegetables is generally considered safe.
