Solgar Methylcobalamin formula is a “body-ready” Vitamin B12 offered in a convenient nugget dosage form. Methylcobalamin is the active, coenzyme form of Vitamin B12. B12 can be found in foods such as meat, fish, and dairy products, it can also be made in a laboratory. Vitamin B12 is required for the proper function and development of the brain, nerves, blood cells and many other parts of the body. Symptoms of vitamin B12 deficiency include fatigue, muscle weakness, shortness of breath, dizziness, numbness, heart palpitations, bleeding gums and mouth sores, nausea and poor appetite. While the body can readily absorb Vitamin B12 as cobalamin, it must further convert it to a coenzyme form, methylcobalamin, to become metabolically active. In this form, it is bioidentical to the predominant and active form found in the body. This food supplement is suitable for vegetarians.
