What is D-Mannose?

D-Mannose is the C2 epimer of the sugar D-Glucose. D-Mannose can be obtained from plant sources such as Chinese jujube, hemicellulose hydrolysate of orange peel, litchi pericarp, apple flesh, cranberries, mangoes, used coffee grounds, etc. It can also be found in baker’s yeast, human serum and egg albumin. D-Mannose is an intermediate product required by the human body in protein and glycoprotein synthesis.[1]

D-Mannose can benefit our immune system and have beneficial effects against urinary tract infections (UTIs), diabetes, metabolic syndrome, and other conditions.[1-3]

What are the Benefits of D-Mannose?

D-Mannose supports urinary tract health, by binding to floating E. coli bacteria in the urine. This can help with eliminating E. coli related UTIs when taken prophylactically.[4-6]

D-Mannose was shown to be beneficial in managing UTI in women with acute cystitis.[3] D-Mannose when taken prophylactically after UTIs can reduce the recurrence of UTIs, which was similar to the prophylactic effects of a standard antibiotic.[2] D-Mannose showed lesser occurrence of UTIs when used by Multiple Sclerosis patients as a preventative agent, both in patients with or without catheters.[7] D-Mannose supplements when taken in combination with N-Acetyl Cysteine and Morinda citrifolia extract has also shown preventative properties in UTI.[8]

Research from decades back indicated the rapid metabolic effects of D-Mannose.[1] D-Mannose has insulin secretary effects on the pancreas and enhances insulin sensitivity.[1, 9] D-Mannose supplementation is beneficial in autoimmune responses in diabetes and inflamed lungs in asthma, and additionally mannose binding proteins are involved in immune response pathways.[1, 10-12]

Why Take D-Mannose Supplements?

D-Mannose can help in managing UTI caused by E. coli strains and prevent recurrence of a UTI when taken regularly after a UTI treated with an antibiotic. It is rapidly metabolized in the body and less likely to be stored as fat, hence it can be used as a sugar substitute. Most common dosages in clinical studies were ranging from 2000 mg to 3000 mg daily.[1-5, 7]

What are the Most Common Side Effects of Taking D-Mannose?

Diarrhea is the most common side effect associated with D- Mannose use.[2, 14-18] D-mannose can cause loose stools and bloating.[16-18]

What are the Precautions and Warnings with D-Mannose Use?

Higher doses of D-Mannose can cause kidney problems.[15, 16] D-Mannose may cause blood sugar problems, so patients with diabetes should avoid using D-Mannose or use it with caution. Avoid using of D-Mannose during pregnancy and breastfeeding since no current evidence is available for these conditions.[15, 16]
