Hi there

Endometriosis is often caused by a Candida problem, a fungal overgrowth of the vagina, intestine or throat or indeed, all those!
Wrong diet is the main cause of candida. Simple carbs need to be avoided.
Grains and grain products are associated with a whole range of problems, including carbohydrate addiction and yeast infections, or candidiasis. Sensitivity or allergy to dairy can be the cause of diarrhea, anemia, cramps, muscle spasms, and can lead to serious malabsorption problems that result in chronic deficiencies that can be the cause of depression, fatigue, disorders of the glands, alcoholism, and has also been implicated in rheumatoid arthritis, schizophrenia, endometriosis cancer and multiple sclerosis. Candida thrives in stale, dank and airless environments. So does cancer. Indeed some researchers have indicated Candida could be a fore runner to cancer.
All fungus likes these conditions. Oxygenate the area and candida dies off. Vitamin C is the main oxygen carrier in the body, and I would recommend at least 3000 mg daily, spread out during the day. As the uterus is a glandular organ I recommend 75 mg of zinc, the food of the glandular system.
Zinc is an essential trace mineral that is a component of over 200 enzymes, and functions as part of more enzymatic reactions than any other mineral. Zinc is readily absorbed in the upper small intestine. The body only absorbs the amount that it needs and discards the rest through the feces. zinc is stored in the liver, pancreas, kidney, bones, and voluntary muscles, parts of the eyes, glands, sperm, skin, hair, and fingernails. However, because the small intestine only absorbs what is needed at the time, it is important that zinc be constantly replaced.
Zinc is probably most famous for being an immune system booster. When zinc levels decrease, the number of T cells decreases, thymic hormone levels decrease, and many white blood cell functions cease.
Both Zinc and Vitamin C have antiviral properties.

Good luck
