Nutritional Supplement
D-Mannose
Possible Deficiencies
As D-mannose is not an essential nutrient, except in certain rare genetic disorders people produce sufficient amounts to provide for the bodies' needs.
Side Effects
Test tube and animal studies suggest that consuming large amounts of mannose might lead to birth defects,6,7 although the amounts of mannose used on those studies were far greater than the amounts a person would ingest from food or from a supplement to treat a urinary tract infection. Nonetheless, until more is known, pregnant women should use supplemental mannose with caution.
