d-mannose may alleviate psoriasis
We explored whether d-mannose can help alleviate psoriasis, an autoimmune condition that causes significant discomfort. Our study demonstrated that both oral and topical applications of d-mannose were effective in reducing psoriasis symptoms in mice.

We discovered that it works by lowering levels of a protein called HIF-1α and the chemokine CCL20 in skin cells. This inhibition interrupts the harmful cycle between keratinocytes and Th17 immune cells. Overall, this suggests d-mannose could be a helpful treatment option for managing psoriasis.

Frequently Asked Questions

An autoimmune disorder occurs when the body's immune system mistakenly attacks its own healthy cells and tissues, believing them to be foreign invaders, such as bacteria or viruses. This reaction can lead to inflammation, tissue damage, and impaired function of the affected organs. There are over 80 known autoimmune diseases, including rheumatoid arthritis, lupus, multiple sclerosis, and type 1 diabetes, each with its own specific symptoms and treatment options. The exact cause of these disorders is still unclear, but a combination of genetic, environmental, and hormonal factors is believed to play a role in their development.

Diagnosis of autoimmune disorders often involves a combination of physical examinations, assessment of symptoms, blood tests, and imaging studies to evaluate organ involvement. Treatment typically focuses on managing symptoms and controlling the immune response using medications such as corticosteroids, immunosuppressants, and biologics. In addition to medication, lifestyle modifications, such as stress management and a balanced diet, can be beneficial in managing symptoms. If you suspect you have an autoimmune condition, it's important to consult a healthcare professional for proper evaluation and tailored treatment options.

D-mannose is a type of simple sugar that is closely related to glucose. It is naturally found in various fruits and plants, including cranberries, apples, and peaches. D-mannose has garnered attention primarily for its potential benefits in supporting urinary tract health. Research suggests that it may help prevent urinary tract infections (UTIs) by inhibiting the adhesion of bacteria, such as E. coli, to the walls of the urinary tract.

Many people consider D-mannose as a natural supplement to support urinary tract function, particularly for those who experience recurrent UTIs. Available in powder or capsule form, it is often taken for preventative purposes or during an active infection, thanks to its ability to promote urinary health. While more research is needed to fully establish its efficacy, D-mannose is generally regarded as safe for most individuals, albeit it’s always a good practice to consult with a healthcare professional before beginning any new supplement regimen.
