B12 THERAPIES: INJECTIONS/SHOTS Vitamin B12 injections, also called shots, are one of the most common and effective ways to treat a deficiency

In contrast, there is some evidence of an enhancement of the maximum absorption via intrinsic factor, by up to a factor of 2, when the vitamin B12 is accompanied by food, but this is not consistently observed and probably only applies when the food quantity and vitamin B12 dose are sufficient to slow the passage of the vitamin B12 through the small intestine enough (about three hours or more) to allow each intrinsic factor receptor to absorb two molecules of vitamin B12 from the oral dose rather than one
Some people find that they prefer to have smaller quantities of B12 injected weekly or fortnightly, and others would rather take larger doses of B12 monthly
Ideal candidates include individuals experiencing unexplained fatigue unresponsive to sleep and stress management, vegetarians and vegans lacking dietary B12 sources, adults over 50 with age-related absorption decline, patients with digestive disorders affecting nutrient absorption, those taking medications that deplete B12, and anyone seeking natural energy support without stimulants
