Metabolics High Quality Nutritional Supplements What Are The Best Forms Of Vitamin B12 Supplements? | I've decided to produce a short blog post this week on the types of supplements containing B12. There are 4 supplemental forms of Vitamin B12 which can be found below. Hydroxocobalamin: Is not a form normally found in the human body, primarily produced by bacteria but can be converted in the body to useable, coenzyme forms of B12, methylcobalamin and adenysylcobalamin, the only forms able to cross the blood brain barrier. Interestingly, Hydroxocobalamin attaches itself to cyanide and is therefore used for smoke inhalation victims If glutathione is low the conversion from hydroxocobalamin will be blocked and methylcobalamin would be the preferred form of B12. Cyanocobalamin: Is the cheapest and most stable form of B12 and has a long shelf life but needs to have the cyanide molecule taken off, so has an extra conversion before being converted to methyl or adenyslcobalamin.
With a certain eye condition, (Lebers hereditary optic neuropathy) cyanocobalamin should not be used. Methylcobalamin: This is the most natural form of B12 and needs no converting .It is already in its “ready to use” form and is a more expensive form. Methylcobalamin is the active coenzyme form necessary for any biological activity. It also is the least stable with the shortest shelf life, converting back to hydroxycobalamin if not stored correctly. Methylcobalamin is sometimes referred to as “active B12” as it is in a form ready to be used by the cells. : This is also an “active “ B12 form, making this coenzyme immediately available for use by the body. It is required for an enzyme known as MCM (Methylmalonyl Coenzyme A mutase), which resides in the mitochondria and is needed to make succinyl CoA to produce energy in the citric acid cycle. In humans adenyslcobalamin is found mainly in the tissues especially the liver. It is the primary form of B12 found in non-human animals.
Stability of B12 All forms of B12 are stable when protected from light. Light exposure cleaves the cyanide with the production of hydroxycobalamin. The B12s have an optimal stability at a PH4.00-4.5, even at higher temperatures. In the presence of acid or alkaline mediator the presence of reducing agents such as ascorbic acid the vitamin is destroyed to a greater extent. It is therefore advisable that B12 is not taken with fruit juice. Metabolics: The Practitioners Choice As a practitioner we know that you want the best for your patients.

Having a healthy amount of vitamin B12 in your body will allow your nervous system to function normally and effectively.[1] The best way to get enough vitamin B12 is by eating foods that are high in vitamin B12 , but you can also use vitamin B12 supplements. You should also have a good understanding of the benefits of this vitamin so you can take it in good faith. Determine your recommended daily allowance for vitamin B12. Every person should consume a certain amount of vitamin B12 every day, starting from birth. The recommended daily allowances for vitamin B12 are:[2]
0-6 months: 0.4 mcg 7-12 months: 0.5 mcg 1-3 years: 0.9 mcg 4-8 years: 1.2 mcg 9-13 years: 1.8 mcg Over 14 years: 2.4 mcg Teen girls and women who could become pregnant or who are breastfeeding should consume at least 2.8 mcg of vitamin B12 a day. Get a diagnosis for vitamin B12 deficiency from your doctor. A lack of vitamin B12 can cause symptoms such as fatigue, a loss of appetite, constipation, and weight loss. However, these symptoms can also be an indication of a different disorder or issue. It’s important that you speak to your doctor and receive an official vitamin B12 deficiency diagnosis before you take vitamin B12 supplements. Your doctor may also be able to give you guidance of certain brands or types of vitamin B12 supplements that may be right for you. Vitamin B12 supplements can have adverse effects or fail to be effective when taken with certain medications, such as medications to treat acid reflux, GERD, and peptic ulcers.
Medication to treat diabetes, like Metformin, can also reduce your body’s ability to absorb vitamin B12. Talk to your doctor or pharmacist before taking vitamin B12 supplements if you are taking any of these medications. Be aware of the two types of vitamin B12 supplements. There are two types of vitamin B12 supplements that you can take, cyanocobalamin and methylcobalamin. Cyanocobalamin is the inactive form of vitamin B12 but it works as well as methylcobalamin, which is the active form of vitamin B12. Most supplements that contain methylcobalamin are more expensive than supplements that contain cyanocobalamin. As long as you are not taking any medications that could interact negatively with vitamin B12 supplements, either form of vitamin B12 should be effective. Vitamin B12 supplements come in tablets, capsules, and liquid form. There is also a sublingual form that dissolves under your tongue. Look for vitamin B12 supplements derived from whole foods. When buying vitamin B12 supplements from health food stores or in the vitamin aisle of your local pharmacy, you should look for information on the label confirming the supplement is derived from whole foods.
Though vitamins derived from whole foods may be more expensive, this will ensure the vitamin is of the highest quality. Keep in mind vitamin supplements are not strictly regulated by the Federal Drug Association (FDA) and are only loosely regulated under the Dietary Supplement Health and Education Act of 1994 (DSHEA). It is the responsibility of the manufacturers to test the safety of their products and to label their products properly. Check the label for independent seals of approval. Many supplements use independent labs to test their products and receive seals of approval for their quality. Look on the label of the supplements from seals of approval from Consumer Labs, the Natural Products Association (NPA), LabDoor, and the United States Pharmacopeia. You can also go directly to the websites of any of these independent labels to see if the manufacturer of the supplement is listed with seals of approval. However, if the supplement does not have any seals of approval, this does not necessarily mean the product is faulty.
Getting checked and approved by an independent lab is completely voluntary for supplement manufacturers. Look for vitamin B12 supplements that contain folate, not folic acid. Folate is vitamin B12 that is naturally found in many foods, but folic acid is the synthetic form of folate and should be avoided. Taking supplements with folic acid can actually hide a vitamin B12 deficiency, if you have one. Consuming too much folic acid can also increase your risk of certain cancers. Consume more fish and beef. Fish such as trout, salmon, tuna, and haddock all contain high levels of vitamin B12. Clams are also naturally high in vitamin B12. As well, beef products, including beef liver, are high in vitamin B12. Try to add more fish and beef to your diet by having at least one serving a day. Have more yogurt, cheese, and eggs. Dairy products like yogurt and cheese, as well as eggs, are also high food sources of vitamin B12. Whole wheat cereal is also known to have high levels of vitamin B12.
Add whole wheat cereal to your diet by having one bowl a day for breakfast with fruit. Consider taking vitamin B12 supplements if you are a vegetarian or a vegan. Vitamin B12 is not found at high levels in plant foods, so individuals with a plant based diet should make sure they are having more food sources of Vitamin B12. Vegetarians and vegans should consider taking vitamin B12 supplements to avoid developing a vitamin B12 deficiency. Reduce your chances of developing anemia by taking vitamin B12. B12 is necessary for your body to produce enough hemoglobin.[11] If you develop a vitamin B12 deficiency, you may also develop a form of anemia called megaloblastic anemia. Once you have this form of anemia, you can experience symptoms like fatigue, loss of appetite, weight loss, and constipation. You may also experience tingling or numbness in your hands and feet, balance issues, soreness of the mouth or tongue, and depression. Taking vitamin B12 supplements and having more vitamin B12 high foods can help to prevent the development of anemia.
