Sublingual Active Vitamin B-12
Are you getting enough?
Are you getting enough vitamin B12(the energy vitamin)? Many people don’t, and that deficiency can cause some serious problems. Recent studies show that approximately 12% of us are deficient, with an additional 20% of us have marginal (less than optimal levels).
There are a number of risk factors for vitamin B12 deficiency, including poor eating habits, vegetarianism, veganism, gastrointestinal disorders (celiac, IBS, diverticulosis, Chron’s, colitis, etc), malabsorptive disorders, prolonged use of metformin and proton pump inhibitors.
Vitamin B12 is an essential vitamin, that your body needs every day but, your body can’t make vitamin B12. You need to get it either from supplements or animal-based foods every day. Vitamin B12 is a vitamin that helps keep your body’s nerve and blood cells healthy and helps make DNA, the genetic material in all your cells. Vitamin B12 functions as a co-factor for numerous intercellular reactions and is essential for the metabolism of fats and proteins.
Vitamin B12 is used for treating and preventing vitamin B12 deficiency, a common condition in which vitamin B12 levels in the blood are too low. Symptoms include numbness, tingling, loss of feeling sensation, burning sensations, muscle cramps, nerve pain, lethargy, tiredness, poor memory, slow thinking and slowness of reflexes. B12 deficiency may be due to a combination of factors including B12 absorption deficiency (as we age our ability to absorb B12 from food and supplements declines), increasing vegetarianism and veganism (primary dietary source of B12 is animal protein), gastrointestinal disorders and a poor diet (high calorie, high fat, low nutrient diet). B12 is also used to treat pernicious anemia, a serious type of anemia that is due to vitamin B12 deficiency.
Vitamin B12 is used for endurance, energy and stamina. It is also used for memory loss; Alzheimer’s disease; boosting mood, energy, concentration and the immune system; and slowing aging. It is also used for the prevention and treatment of heart disease, infertility, diabetes, sleep disorders, depression, mental disorders, osteoporosis, swollen tendons, AIDS, inflammatory bowel disease, asthma, allergies, preventing cancers, and skin infections.
Oral administration of high-dose vitamin B12 (1000 to 2000 mcg daily) has been found to be as effective as injections in correcting B12 deficiency, regardless of cause. Research shows vegetarians, vegans and patients older than 50 years should consume vitamin B12 supplements, rather than attempting to get vitamin B12 strictly from food sources.
There are two main forms of vitamin B12; Cyanocobalamin and Methylcobalamin. Cyanocobalamin is not found in nature and is synthesized in labs. Methylcobalamin is naturally synthesized by the algae and bacteria animals eat and is found throughout the food chain. Foods that have B12 added almost exclusively use the cyanocobalamin form as it is significantly less expensive.
Cyanocobalamin (also referred to as passive B12) is the most commonly supplemented form of vitamin B12, despite not actually occurring in plants or animal tissues. In other words, outside of the chemically (laboratory) synthesized cyanocobalamin that you encounter as B12 in most vitamin supplements, you would not be able to find this compound in nature. As the name implies, cyanocobalamin contains cyanide. Most people are familiar with cyanide as a poisonous substance. Although the amount of cyanide in a normal B12 supplement is small and from a toxicology point, viewed as insignificant, your body will still need to remove and eliminate this compound. This removal is accomplished through your detoxification systems with substances like glutathione being used up in the elimination of the cyanide.
Methylcobalamin (also referred to as active B12) is better absorbed and retained in higher amounts than cyanocobalamin is. In simple terms, methylcobalamin is used much more effectively. Methylcobalamin is used primarily in your liver, brain and nervous system.
Cyanocobalamin can not be used directly by your body. It first needs to go through a multi-stage conversion process to become active. Unfortunately through each stage of conversion some of the potency is reduced. Conversely, methylcobalamin can be used directly by your body without going through any conversion, or any loss of potency.
Methylcobalamin is the specific form of B12 needed for nervous system health. Because of this it should be the first form of this vitamin thought of to optimize nervous system health.
Because of active B12‘s importance in nervous system health, it is also an important nutrient for vision. In fact, continued visual work (like work on a computer) often leads to a reduction in something called “visual accommodation”. active B12 can significantly improve visual accommodation, while passive B12 is ineffective.
Elevated levels of homocysteine is an indication of decreased levels of active B12. Homocysteine has received a tremendous amount of emphasis in the scientific literature because of its associations with heart disease and a variety of other health conditions. Active B12 supplementation can help lower homocysteine levels.
The most well studied use of active B12 has to do with sleep. Although the exact mechanism of action is not yet clear, it is possible that active B12 is needed for the synthesis of melatonin. Available information indicates that active B12 can modulate melatonin secretion, enhance light-sensitivity, and normalize circadian rhythm (your 24-hour clock). Because of this, individuals supplementing this form of B12 often have improved quality of sleep, often will require slightly less sleep, and will not uncommonly report that they feel a bit more refreshed when waking in the morning. Active B12 is particularly effective when your 24-hour clock is not running smoothly. This may be indicated by a need for excessive sleep, changing sleep-wake cycles, or a tendency to have altered sleep wake patterns. As examples, you might require 10-12 hours of sleep, or you might not feel tired until 2-3 am and you might wake at noon, or you might find that you wake a bit later every day and go to be a bit later every night. Under all of these circumstances the combination of active B12 (about 3000 mcg daily) and exposure to bright light in the morning can help reestablish your 24-hour clock.
Because of active B12‘s impact on 24-hour clock and the cycles that feed this, it is also an important vitamin to regulate your 24-hour release of the stress hormone cortisol. This seems to be particularly important for blood types A and AB. Active B12 also seems to result in a better 24-hour maintenance of body temperature. Typically individuals supplementing with active B12 have higher temperatures in the later hours of the daytime. This usually corresponds with improved alertness at the same time of the day. While this can be of importance to all blood types, low body temperatures seems to be an area of greater challenge for blood types A’s and B’s.
