The studies of the Chronic Fatigue Syndrome by renown doctors revealed that B12 injections dramatically improve energy and sleep quality.
For this reason, doctors administer Vitamin B12 shots in case their patients complain about a lack of energy.
Nowadays, Vitamin B12 is available in pills and supplements. The stomach acids that provide a natural breakdown of food also breakdown supplements that we take. Our body can only absorb as much as it naturally absorbs, which means that it will only absorb a small amount of B12 from the pill. Moreover, as we get older, our body’s ability to absorb nutrients through digestion decreases. Some adults even become completely unable to absorb B12 into their body. Injections allow you to directly supply your body with Vitamin B12.
Vitamin B12 is water-soluble, which means that it quickly dissolves in water and does not remain in the body. It gets eliminated through urine within 24-72 hours depending on a person’s physical activity and water intake. Due to fast elimination, frequent supplementation is required to avoid Vitamin B12 deficiency and its consequences.
