Hi, Thank you for your query. I can understand your concerns. There aren t any supplements that can specifically help polycythemia vera. Avoid iron supplements or iron-rich foods.A state of iron deficiency prevents an accelerated reexpansion of the red cell mass. Eat antioxidant foods, including fruits (such as cherries, and tomatoes), and vegetables (such as squash and bell peppers). Avoid refined foods, such as white breads, pastas, and especially sugar. Eat fewer red meats and more lean meats, cold-water fish, tofu (soy, if no allergy), or beans for protein. Use healthy oils, such as olive oil or vegetable oil. Reduce or eliminate trans-fatty acids, found in commercially baked goods such as cookies, crackers, cakes, French fries, onion rings, donuts, processed foods, and margarine. Avoid caffeine, alcohol, and tobacco. Drink 6 - 8 glasses of filtered water daily. Regards Dr. T.K. Biswas M.D. Mumbai
