HFE Assist II (Iron Block) for normal to higher iron. Much of the food we consume is fortified with iron. Those with genetic variants in the iron-regulating genes (HFE) may be at risk for absorbing excess iron, which can create excess inflammation and oxidative stress in the body. This product contains nutrients to reduce iron absorption and Lactoferrin to modulate iron usage. Taking one to two capsules with meals may be an effective way to support healthy iron levels.
