Vitamins B12 And D3 For People Living With Neuropathy And HIV


Today's post from nybc.wordpress.com (see link below) looks at Vitamins B12 and D3; two of the key vitamins people should ensure remain at healthy levels, when living with the side effects of HIV including neuropathy. Of course, the New York Buyers Club is a very well known supplier of supplements and vitamins and this blog makes a point of not advertising for commercial sites but this article does give some very good medical information based on the findings of the Canadian, Catie HIV organisation and reliably informs you of the reason why you might need supplementation - after that the decision is yours as to where you buy what you need. Personally, I would always check with your doctor first - a simple blood test will tell you if you're deficient in any vitamin or mineral areas and it's possible you can get any supplements free on prescription after that - if not, perfectly good supplements can be bought cheaply almost everywhere these days. There are also various other articles about B and D vitamins to be found in the list to the right of this blog and they may help further with your decision making.

Why Vitamins B12 and D3 Are Especially Important to People with HIV

Our friends at the Canadian AIDS Treatment Information Exchange (CATIE), a Canadian government-supported education and prevention organization, recently published an excellent guide to managing HIV medication side effects. This online guide covers the territory from body shape changes, to gastrointestinal disorders, to neurological effects, to emotional wellness, to fatigue, to sexual difficulties.

The Appendix to this guide focuses on two vitamins, both of which have been highlighted as especially important for people with HIV: B12 and D3. Deficiency of these two vitamins appears to be common among people with HIV, and supplementing to correct the deficiency can bring about major improvements in health. So it’s definitely worthwhile to check your B12 and D3 status, and, if you’re deficient, find a good supplementation strategy. Note that NYBC stocks both of these inexpensive vitamins: the methylcobalamin form of Vitamin B12 recommended below; and several strengths of Vitamin D3, including the commonly recommended D3 – 2500IU format.

Below are the CATIE recommendations:

Vitamin B12

A number of studies have shown that vitamin B12 is deficient in a large percentage of people with HIV, and the deficiency can begin early in the disease. Vitamin B12 deficiency can result in neurologic symptoms — for example, numbness, tingling and loss of dexterity — and the deterioration of mental function, which causes symptoms such as foggy thinking, memory loss, confusion, disorientation, depression, irrational anger and paranoia. Deficiency can also cause anemia. (See the section on Fatigue for more discussion of anemia.) It has also been linked to lower production of the hormone melatonin, which can affect the wake-sleep cycle.

If you have developed any of the emotional or mental symptoms mentioned above, especially combined with chronic fatigue, vitamin B12 deficiency could be contributing. This is especially true if you also have other symptoms that this deficiency can cause, including neuropathy, weakness and difficulty with balance or walking. On the other hand, these symptoms can also be associated with HIV itself, with hypothyroidism or advanced cases of syphilis called neurosyphilis. A thorough workup for all potential diagnoses is key to determining the cause.

Research at Yale University has shown that the standard blood test for vitamin B12 deficiency is not always reliable. Some people who appear to have “normal” blood levels are actually deficient, and could potentially benefit from supplementation.

The dose of vitamin B12 required varies from individual to individual and working with a doctor or naturopathic doctor to determine the correct dose is recommended. Vitamin B12 can be taken orally, by nasal gel or by injection. The best way to take it depends on the underlying cause of the deficiency, so it’s important to be properly assessed before starting supplements. For oral therapy, a typical recommendation is 1,000 to 2,000 mcg daily.

One way to know if supplementation can help you is to do a trial run of vitamin B12 supplementation for at least six to eight weeks. If you are using pills or sublingual lozenges, the most useful form of vitamin B12 is methylcobalamin. Talk to your doctor before starting any new supplement to make sure it is safe for you.

Some people will see improvements after a few days of taking vitamin B12 and may do well taking it in a tablet or lozenge that goes under the tongue. Others will need several months to see results and may need nasal gel or injections for the best improvements. For many people, supplementation has been a very important part of an approach to resolving mental and emotional problems.

Vitamin D


Some studies show that vitamin D deficiency, and often quite severe deficiency, is a common problem in people with HIV. Vitamin D is intimately linked with calcium levels, and deficiency has been linked to a number of health problems, including bone problems, depression, sleep problems, peripheral neuropathy, joint and muscle pain and muscle weakness. It is worth noting that in many of these cases there is a link between vitamin D and the health condition, but it is not certain that a lack of vitamin D causes the health problem.

A blood test can determine whether or not you are deficient in vitamin D. If you are taking vitamin D, the test will show whether you are taking a proper dose for health, while avoiding any risk of taking an amount that could be toxic (although research has shown that toxicity is highly unlikely, even in doses up to 10,000 IU daily when done under medical supervision). The cost of the test may not be covered by all provincial or territorial healthcare plans or may be covered only in certain situations. Check with your doctor for availability in your region.

The best test for vitamin D is the 25-hydroxyvitamin D blood test. There is some debate about the best levels of vitamin D, but most experts believe that the minimum value for health is between 50 and 75 nmol/l. Many people use supplements to boost their levels to more than 100 nmol/l.

While sunlight and fortified foods are two possible sources of vitamin D, the surest way to get adequate levels of this vitamin is by taking a supplement. The best dose to take depends on the person. A daily dose of 1,000 to 2,000 IU is common, but your doctor may recommend a lower or higher dose for you, depending on the level of vitamin D in your blood and any health conditions you might have. People should not take more than 4,000 IU per day without letting their doctor know. Look for the D3 form of the vitamin rather than the D2 form. Vitamin D3 is the active form of the vitamin and there is some evidence that people with HIV have difficulty converting vitamin D2 to vitamin D3. Historically, vitamin D3 supplements are less commonly associated with reports of toxicity than the D2 form.

It is best to do a baseline test so you know your initial level of vitamin D. Then, have regular follow-up tests to see if supplementation has gotten you to an optimal level and that you are not taking too much. Regular testing is the only way to be sure you attain — and then maintain — the optimal level for health.

With proper supplementation, problems caused by vitamin D deficiency can usually be efficiently reversed.

What Is Vitamin B12 Deficiency


The last 2 posts and the next 3 posts all relate to Vitamin B12 and neuropathy. If you weren't a hypochondriac before reading these, you may well be afterwards, so taking a sensible view of the many symptoms shown here is advisable. Strangely, most HIV and/or neuropathy patients aren't standard tested for B12 deficiency but it may well be worth asking your doctor to do exactly that - it may explain several things. All 5 posts come from the same site B12patch.com (see links below the articles), which is pretty much an 'all you would ever want to know' type of information site but the descriptions of what neuropathy is are accurate and honest and explained in language that we all can understand. Very interesting and worth discussing with your doctor if there's time, especially if you're considering taking B12 supplement pills (usually need Folic acid to help absorption) - injections may be better in your case.

Is Vitamin B12 Deficiency an Autoimmune Disorder? Yup.
If you’ve been diagnosed with vitamin B12 deficiency, you’re probably wondering, “How did this happen?” Unless you’re a vegan or a gastric bypass patient, it’s possible that vitamin B12 deficiency resulted from an autoimmune disorder that causes pernicious anemia.

Vitamin B12 deficiency- what are the symptoms?

Vitamin B12 is essential for maintaining your nervous system, psychological health, and your metabolism. Pernicious anemia causes a wide range of debilitating symptoms that interfere with daily life, and is one cause of B12 deficiency.
Symptoms of vitamin B12 deficiency-pernicious anemia may include:
  • Everyday fatigue, despite sleeping well
  • Brain fog- confusion
  • Impaired concentration
  • Impaired memory
  • Depression
  • Anxiety
  • Mood swings
  • Irritability
  • Painful numbness and tingling in hands and feet
  • Tingling or burning sensation in mouth and tongue
  • Slower reflexes
  • Difficulty walking normally
  • Stomach upset
  • Infertility or frequent miscarriages and stillbirths

Vitamin B12 deficiency- what are the causes?

There are many reasons why an individual may develop vitamin B12 deficiency. First off, if you eat a diet rich in sources of vitamin B12, including beef, poultry, fish, and milk, then you should not under any normal circumstances become deficient in vitamin B12 levels.
  • Following a vegan diet is a major risk factor for vitamin B12 deficiency. Vitamin B12 occurs naturally in animal-based foods, the richest sources being liver, shellfish, and many lean meats. Unless you supplement your vegan diet with vitamin B12, then you will eventually become depleted, as few plant-based products are infused with substantial amounts of vitamin B12.
  • Certain lifestyle choices may interfere with vitamin B12 absorption, including stomach or intestinal surgery (such as gastric bypass), alcohol abuse, and using certain B12-inhibiting medications (such as metformin or protein pump inhibitors [PPIs]).
  • Gastrointestinal diseases, in addition to other diseases that include GI malfunction, may cause vitamin B12 deficiency. These include Crohn’s disease, ulcerative colitis, celiac disease, fibromyalgia, migraine disorder, and chronic fatigue syndrome.
  • The elderly do not produce enough stomach acid to digest vitamin B12 fully, so they are a separate risk group for vitamin B12 deficiency.
  • If none of the above-mentioned risk factors pertain to you, then it’s entirely possible that you suffer from an autoimmune disorder that prevents you from absorbing vitamin B12 from dietary sources. Autoimmune pernicious anemia may take decades to develop and typically goes unnoticed until you reach your thirties or forties.

Vitamin B12 deficiency from autoimmune disorder

In order to get vitamin B12 into your blood supply, you need certain digestive enzymes to help you access vitamin B12 from the foods you eat. Intrinsic factor is that necessary enzyme that your body uses to absorb vitamin B12.
For some people, certain antibodies interfere with intrinsic factor, causing your immune system to malfunction. If you have one of the antibodies that interfere with vitamin B12 absorption, then you will never be able to digest vitamin B12, no matter how many hamburgers or fish dinners you eat in your lifetime.

Three types of antibodies cause vitamin B12 deficiency- pernicious anemia. They include:
  • Parietal cell antibody, which prevents the production of intrinsic factor in the stomach.
  • Intrinsic factor antibody, type 1, which prevents the bonding of vitamin B12 to intrinsic factor. About 50%-60% of pernicious anemia patients have this type of antibody.
  • Intrinsic factor antibody, type 2, which allows bonding of vitamin B12 to intrinsic factor, but prevents bonding with receptor from the ileum (the bottommost part of your small intestine).
If you’ve been tested for vitamin B12 deficiency, it’s important that you also take a blood test for the pernicious anemia antibody. Many doctors overlook this important screening, so you might need to ask for it.
Vitamin B12 deficiency autoimmune disorder requires vitamin B12 from non-oral sources, such as vitamin B12 injections, which are available only through prescription.
