In diabetic patients with advanced kidney disease, a study found that high daily doses of B vitamins (folate, B6 and B1) worsen kidney function and double the risk of heart attack, stroke and death (see the Precautions section of the B Vitamins Review for more information). The study shows that people with diabetes and kidney damage should not take high doses of vitamin B and folic acid. This doesn't mean you should stop taking a daily prescription multivitamin. Multivitamins have much lower doses and may have other benefits for you.
Do kidney doctors routinely prescribe vitamin B to diabetic patients with kidney problems? You may need to avoid some vitamins and minerals if you have kidney disease. Some of them include vitamins A, E and K. These vitamins are more likely to build up in the body and can cause harm if ingested in excess. Over time, they can cause dizziness, nausea, and even death.
You should only take these vitamins if your health professional prescribes them for you. There is also some concern about vitamin C. While some people may need to take a low dose of vitamin C, high doses can cause an accumulation of oxalate in people with kidney disease. Oxalate can remain in bone and soft tissue, which can cause pain and other problems over time.
Unfortunately, the body cannot produce B12 like vitamins D and K, so the only way to ensure a sufficient amount of B12 is by eating B12-rich foods or taking vitamin B12 supplements. To increase vitamin B-12 concentrations, vitamin B-12 supplements are often recommended and, among people who do not respond adequately to this treatment, Wolffenbuttel et al recommend intramuscular injections. Key points for patients with kidney disease (not on dialysis) Patients with diabetes and kidney disease damage should not take high doses of vitamin B and folic acid. Folate is a B vitamin that is important in basic cellular processes and is commonly available as folic acid in supplements and fortified foods.
Vegan B12 supplements are developed without using non-plant sources and are as effective as any other supplement. Among participants who had insufficient vitamin B-12 concentrations, 18% used a supplement containing vitamin B-12. Among participants with high folate levels and insufficient vitamin B-12 concentrations, 34% reported taking supplements containing vitamin B12. Low levels of vitamin B12 affect the creation of healthy red blood cells, which in turn affects the amount of oxygen carried by the blood, making you feel tired and without enough energy. Data on the use of supplements were used to define the types and quantities of SUPs consumed in order to estimate the nutrient intake of those SUPs. Your health professional and renal dietician can help you determine what vitamins and minerals you may need by reviewing your health history and blood tests.
Vitamin B12 is crucial for regulating sleep-wake cycles because it increases the body's production of melatonin. A lack of vitamin B12 and folic acid causes the bone marrow to produce larger red blood cells.
