Vitamin B12 Supplements are actually the only nutritional that the body stores in decent amounts. Most people receive acceptable amounts from their diets. However, it has already to be truly separated from the necessary protein in food stuff, an involved procedure.
Vitamin and mineral supplements are truly popular these days, as anyone can plainly see just from the fully stocked shelves of discount department stores, drug stores and health stores. The problem with vitamins is that people believe that they can take as much as they want because they are natural. The truth is that even natural things can harm us.
We must be more cautious with our choices and educate ourselves before increasing the dosages. Below, learn more about how much vitamin B12 should you take, what is safe and what amount could potentially harm you.
Vitamin B12 is also known as Cobalamin and its main role is to avoid anemia. It regulates and forms red blood cells and helps in the absorption of iron. It also helps to maintain fertility and metabolizes fats, proteins and carbohydrates. It protects nerves by producing myelin, and helps to produce acetylcholine which help with memory.
It takes several hours for this vitamin to be absorbed in the digestive tract and, any extra that is not necessary for the body will be excreted in urine. However, some extra will be stored in the liver. This storage could last in the liver for up to five years.
The recommended daily allowance, or RDA, is 2 mcg, with pregnant women requiring more, and this, like any RDA of any vitamin is to avoid deficiency. Those who are taking medication to treat gout, or those who take potassium supplements, vegetarians, the elderly and individuals with AIDS will need higher doses of vitamin B12 for varying reasons.
Taking up to 100 mg of the vitamin has not shown any evidence of toxicity, so it is safe to take without fear of overdose. Certainly, you can take more than what is written on the label, especially if you are deficient, which is rare. However, some evidence points to the elderly who should take more because their bodies cannot naturally extract the vitamin from their foods due to low gastric acids in their stomachs.
Furthermore, supplements can help avoid illnesses and diseases, but increasing the dosage should be done under a doctor’s supervision.
For the elderly, shots are the solution because of their faltered digestive system which would still prohibit the vitamin from being absorbed into the system. It is also possible to avoid or treat osteoarthritis, tinnitus, and varicose veins by taking increased dosages of vitamin B12.
The important thing is to discuss the issue with your doctor beforehand.
