is vitamin b12 damaged by heat?
Heat can indeed damage vitamin B12. Vitamin B12 is a water-soluble vitamin that is sensitive to heat, light, and oxygen. It is found in animal products such as meat, fish, poultry, eggs, and dairy products. When these foods are cooked at high temperatures, the vitamin B12 content can be significantly reduced. For example, boiling meat for 30 minutes can destroy up to 90% of the vitamin B12 content. Cooking food at lower temperatures for shorter periods of time can help to preserve the vitamin B12 content. Additionally, adding acidic ingredients such as lemon juice or vinegar to the cooking water can also help to protect the vitamin B12 from heat damage.
do vitamins go bad in the heat?
Yes, vitamins go bad in the heat, but the rate at which they degrade depends on the specific vitamin and the temperature. Some vitamins, like vitamin C and B vitamins, are more sensitive to heat than others, like vitamin A and E. Typically, vitamins begin to lose their potency when exposed to temperatures above room temperature. For example, vitamin C can lose up to 10% of its potency when stored at 100 degrees Fahrenheit for just one day. At higher temperatures, the degradation rate increases significantly. To maintain the potency of vitamins, it’s best to store them in a cool, dark place, away from heat and light. A refrigerator or freezer is typically the best place to store vitamins, although some vitamins, like vitamin C, can also be stored at room temperature for short periods of time.
when should i take b12 morning or night?

what blocks b12 absorption?
B12, also known as cobalamin, is an essential nutrient that plays a crucial role in various bodily functions, including the production of red blood cells, DNA synthesis, and nerve function. There are several factors that can hinder the absorption of B12, leading to a deficiency. One common cause is a lack of intrinsic factor, a protein produced by the stomach that helps absorb B12 in the small intestine. Another factor is a condition called pernicious anemia, in which the body’s immune system attacks the cells that produce intrinsic factor. Additionally, certain medications, such as metformin and proton pump inhibitors, can interfere with B12 absorption. Furthermore, gastrointestinal disorders, such as Crohn’s disease and celiac disease, can damage the small intestine and impair B12 absorption. Prolonged alcohol consumption can also lead to B12 deficiency, as alcohol can interfere with the absorption and metabolism of the nutrient. Lastly, certain surgical procedures, such as gastric bypass surgery, can alter the anatomy of the digestive tract and make it more challenging for the body to absorb B12.
what form of b12 is best absorbed?
Methylcobalamin and adenosylcobalamin are the two forms of vitamin B12 that are most easily absorbed by the human body. Methylcobalamin is the predominant form found in food sources, while adenosylcobalamin is the form used by the body for most metabolic processes. Both forms of B12 are absorbed in the small intestine, but methylcobalamin is better absorbed than adenosylcobalamin. The absorption of B12 is also affected by a number of factors, including the presence of stomach acid, the type of food being consumed, and the overall health of the individual. For individuals with impaired absorption of B12, such as those with pernicious anemia, injections of vitamin B12 may be necessary to maintain adequate levels of the vitamin in the body.
what causes vitamin b12 deficiency?
