Vitamin B12 Methylcobalamin 1500 mcg Energy, Nerve & Mood Support | 120 Tablets

Methylcobalamin can generally be taken daily when used as directed, and vitamin B12 has no established tolerable upper intake level because of its low potential for toxicity. However, the appropriate dose depends on your nutritional needs and the reason for supplementation. Pure Nutrition Vitamin B12 Methylcobalamin provides 1500 mcg of vitamin B12 per tablet, which is a high-dose supplement compared with the adult recommended intake of 2.4 mcg per day. If you are taking B12 for a diagnosed deficiency, have a medical condition, are pregnant or breastfeeding, or take medicines regularly, consult a healthcare professional about the appropriate dose and duration.

Methylcobalamin is a form of vitamin B12; vitamin B12 is the broader name for a group of related compounds called cobalamins. Methylcobalamin is one of the metabolically active forms of B12. Other forms include cyanocobalamin and hydroxocobalamin, which can be converted into biologically active B12 forms in the body. So, methylcobalamin is vitamin B12, but not every vitamin B12 supplement contains methylcobalamin.

A methylcobalamin B12 tablet is used to supplement vitamin B12 and help maintain normal nerve function, red blood cell production, DNA synthesis, and energy metabolism. It can be especially useful when dietary intake is insufficient or when vitamin B12 deficiency has been identified. People following vegetarian or vegan diets can be at greater risk of inadequate B12 intake because naturally occurring vitamin B12 is mainly found in animal-derived foods. Fortified foods and B12 supplements can help meet nutritional needs when dietary intake is insufficient.

People with a known allergy or sensitivity to vitamin B12 or any ingredient in the supplement should avoid it. Anyone who has been diagnosed with vitamin B12 deficiency, has significant absorption problems, has neurological symptoms, is pregnant or breastfeeding, or takes medicines regularly should consult a healthcare professional before starting high-dose B12 supplementation. Certain medicines can also affect vitamin B12 status. For example, metformin can reduce vitamin B12 absorption, while long-term use of gastric acid-reducing medicines can affect B12 absorption from food. People with suspected deficiency should not rely only on supplements to self-treat unexplained symptoms.

Vitamin B12 can generally be taken at any convenient time of day, but morning is a practical choice for many people because B12 is involved in normal energy metabolism. Consistency is more important than choosing a specific time of day. If B12 supplements cause stomach discomfort, taking them according to the product directions and with food can be more comfortable. If you are taking B12 for a diagnosed deficiency, follow your healthcare professional's dosing instructions. If you are taking B12 specifically because of low energy, improvement is not necessarily immediate. The time required to notice improvement depends on factors such as your starting B12 level, absorption, diet, and consistency of supplementation.
