Elderberry, Burdock Root, Cascara Sagrada Bark, Sarsaparilla Root, Quassia Wood Chips, Vervain, Stinging Nettle Leaf, Roasted Dandelion Root All ingredients in our Iron Fluorine tea are non-GMO (not genetically modified) and are wild crafted. In order for iron to be most useable by the body, it needs to come from an “electrical” natural source. The same way our body is electric, it needs similar foods for nourishment and highest absorption potential. Synthetically made iron may not be as absorbable by the body and can often be toxic if not properly absorbed by the body. This is why it may be a good option to take our Iron Fluorine Herbal tea as your daily iron supplement.
