Seaweed and kelps reduces yeast infections by stimulating the immune system and interferon production and enhancing natural killer cell function that strengthen your defense against invading yeast such as candida albicans. Many very important glyconutrients (polysaccharides with long-chain complex sugars) that help your body to fight disease, yeast infections, as well as pathogenic bacteria and viruses, have been identified in brown seaweed as asco, laminaria and fucos. The extremely significant saccharides is fucoidan. Others include galactose, L-fructose, mannose and xylose.
Seaweed and kelps balances blood sugar levels, which may help in preventing yeast infections since these organisms thrive in high glucose environment.
