As a precautionary measure, lactating women may not be advised to take Fulvic acid. Fulvic and Humic Acid plays a role in protecting your cells from oxidation that occurs from environmental toxins. It makes nutrients more soluble and available for use by the cells in your body. Fulvic and Humic Acid is an antioxidant that fights off the damage incurred from free radicals that enter your body through the food you eat and through outside environmental toxins. It is an electrolyte that helps balance the minerals that drive neurons in your brain. Fulvic and Humic Acid is very rich in minerals with fulvic acid, amino acids and humic acid which help with digestion and immune system functions in pregnant women. I have recommended Renew with Fulvic in the past for pregnant ladies.
