ANSWER: It is generally recommended to take 1,500-2,000 milligrams of D-mannose per day to help prevent urinary tract infections (UTIs).

If you are currently experiencing a UTI, you can take 3,000-6,000 milligrams per day to help clear the infection.

It is important to consult with your healthcare provider before taking any supplements to ensure it is safe for you and to determine the appropriate dosage for your individual needs.

What is to much?

While D-mannose is generally considered safe and well-tolerated, there is a maximum safe amount of D-mannose that should be consumed in a day.

According to the World Health Organization (WHO), the acceptable daily intake (ADI) of D-mannose is 1.5 grams per kilogram of body weight per day. For a person who weighs 70 kilograms (154 pounds), this translates to a maximum daily intake of 105 grams of D-mannose.

However, it’s important to note that most D-mannose supplements come in doses ranging from 500 milligrams to 2 grams per serving. It is unlikely that a person would exceed the maximum safe intake of D-mannose by taking recommended doses of supplements.

It is also important to note that D-mannose is not a substitute for medical treatment for UTIs. If you have symptoms of a UTI, it is important to see a healthcare professional for proper diagnosis and treatment. While D-mannose may help support urinary tract health, it is not a cure for UTIs and should not be used as the sole treatment for these infections.
