🧪 Formulation Notes

Supports thyroid function

Kelp is a type of seaweed that grows underwater, and is an excellent source of iodine. Nature's Way sustainably sources kelp from cold water climates, like Nova Scotia, where the wildcrafters carefully cut the leaves, without uprooting the plants to allow for regrowth in the future.

At Nature's Way, we believe nature knows best. That's why our mission is to seek out the best herbs the earth has to give. It's the way we deliver uncompromising quality and help you live healthier.
