ANSWER: D-Mannose is a naturally occurring simple sugar that is found in many fruits and vegetables, including cranberries, apples, oranges, and peaches. It is also produced by the human body in small amounts.
D-Mannose can be isolated and purified from natural sources, such as cranberries or birch bark, or it can be synthesized in the laboratory.
Cranberries are a particularly rich source of D-Mannose, and many D-Mannose supplements are derived from cranberry extract. The high concentration of D-Mannose in cranberries is believed to be responsible for their ability to prevent and treat urinary tract infections (UTIs).
D-Mannose supplements are available in various forms, including capsules, powders, and tablets. Some products may also contain other ingredients, such as cranberry extract or probiotics, which are believed to enhance the effects of D-Mannose.
In conclusion, D-Mannose is a naturally occurring simple sugar that is found in many fruits and vegetables, including cranberries. It can be isolated and purified from natural sources or synthesized in the laboratory. Many D-Mannose supplements are derived from cranberry extract, which is a particularly rich source of D-Mannose.
