The answer is: Yes, you do get a burst of energy, but not because you needed a bump in vitamins. While B vitamins DO help give you energy, it’s not instantaneous. (That surge in energy you feel is from the caffeine also loaded into the bottle.)

While megadoses of up to 2,000 mcg are considered safe in treating B12 deficiency, it’s always best to avoid excessive amounts of any vitamin, especially when it’s not needed.

There is no consensus on the definition of high or elevated B12. Previous studies have chosen a variety of levels to represent high or very high B12 (pmol/l) levels. Some examples include: 664.2¹⁹; 513¹; 700 (high) and 1500 (very high)¹¹; and 601 (high) and 1000 (very high)¹⁰.

5-Hour Energy, for example, claims to provide more than 8,000% of the recommended daily intake for B12, which is found in animal products and helps form red blood cells, and 2,000% of the recommended intake of B6.

It may take a few weeks before your vitamin B12 levels and symptoms (such as extreme tiredness or lack of energy) start to improve. If you have hydroxocobalamin injections to boost your vitamin B12 levels at the start of treatment, the cyanocobalamin tablets may start to work within a few days.

Comparing the sublingual method to vitamin B12 injections, research found that taking B12 under the tongue had a higher absorption rate, making it a better option (Bensky, 2019). Taking vitamin B12 sublingually may also be a good option for people with a condition called pernicious anemia.

B12 shots contain about 100 micrograms of B12, which is roughly 40 times the recommended daily value for an average healthy adult (2.4 micrograms). But these high doses are necessary to help treat people with a deficiency.

In the stomach, hydrochloric acid and enzymes unbind vitamin B12 into its free form. From there, vitamin B12 combines with a protein called intrinsic factor so that it can be absorbed further down in the small intestine. Supplements and fortified foods contain B12 in its free form, so they may be more easily absorbed.
