Ingredient:

Microcrystalline cellulose

Microcrystalline cellulose (MC) is a purified plant fiber that is widely used in food products and in dietary supplement tablets to: 1) bind ingredients together, or 2) help the tablet disintegrate properly.

Following ingestion, MC is not absorbed by the human body. Because it is not absorbed, it has little potential for toxicity. Consumption of large quantities of cellulose may have a laxative effect, but this is unlikely to be a problem for individuals consuming the small amounts included in dietary supplement tablets 1.

This ingredient can be found in the following products in United States:
