15 Facts About Vitamin B12 Injections

5. You might not absorb it all

The body’s capacity to absorb Vitamin B12 is complex. It cannot necessarily absorb a high dose. It is usually recommended that Vitamin B12 be taken in smaller doses on a regular basis. Vitamin B12 is a water-soluble vitamin. It is dissolved in the fluid in the body. Whatever the body doesn’t use, it expels.

Vitamin B12 doesn’t have a long “shelf life” in the body. So, it’s a case of using it or losing it. In the event of a severe deficiency, an injection will give the body an immediate boost. Where there is a mild deficiency, a more metered intake is required.

The fact that your body might not absorb the whole dose of Vitamin B12 is not a medical risk, per se. It’s more related to the fact you take the shot expecting to get the maximum use out of its contents.

It’s hard to overdose on a vitamin such as Vitamin B12 because it is so easily expelled from the body. Nutritionists prefer a more regular dosage pattern than that offered by a concentrated shot.
