Get B12 Fast With At-Home Injections
Pharmaceutical-grade, prescription-only Vitamin B12 shots are vegan and contain cyanocobalamin, a form of B12 that is readily converted for use by the body. Find out how you can give yourself B12 injections right at home to boost your B12 levels and maintain them.
One of the most obvious perks of Vitamin B12 shots is increased energy. Many people report feeling a burst of energy within a day of receiving a B12 injection.2 Although high energy is great and B12 is popular in preventative medicine, B12 shots can benefit the body in more vital ways.
Close to 100 body processes involve B12.2 B12 protects the health of neurons and red blood cells, is needed to produce energy, protects the Central Nervous System (CNS) and supports immunity.2
How Long Do B12 Shots Last?
Most people report that the effects of 1000 mcg of B12 last for about a week and typical dosing is 1x week.
Why B12 Shots Are Effective
There are more than a few obstacles to Vitamin B12 absorption by the body from food and oral supplements. Oral supplements include tablets, capsules, sublingual drops and lozenges. The only way these delivery methods can be used by the body is through absorption in the small intestine.3
In a best case scenario, the body can absorb 2% of oral Vitamin B12 supplements in a 12-hour period.3 It is not known how much B12 from food is available for use by the body but the fact that 15% of the US population3 is Vitamin B12 deficient provides insight. Like many vitamins, how and when the B12 is taken orally affects its absorption.
What Causes B12 Deficiency?
Causes of B12 deficiency include Crohn’s and Celiac disease, prescription and over the counter medications to treat acid reflux and Gastroesophageal Reflux Disease (GERD), prescriptions such as Metformin, medical procedures like bariatric surgery and low levels of the glycoprotein intrinsic factor.3 It’s also common for some people to poorly absorb vitamins for unknown reasons.3
A popular misconception about B12 deficiency is that vegans, vegetarians and the elderly are the only groups at risk for B12 deficiency. It’s true that elderly adults are more prone to B12 deficiency due to a decline in absorption associated with aging.3
It’s also true that sufficient amounts of dietary B12 only comes from animal products, so vegans are at risk for Vitamin B defiency.3
No plants make Vitamin B12 in any significant amount, except perhaps the smallest plant known on earth, duckweed (Wolffia globosa.) Duckweed is being studied due to its nutrient-rich profile which includes Vitamin B12, nine of the essential amino acids, iron, and zinc.4
Overall, studies show that Vitamin B12 deficiency is not limited to age or diet.
How B12 Shots Work
B12 shots are given intramuscularly or subcutaneously which bypasses the digestive system. Parenteral administration (injection) is faster and more efficient than oral supplements and recommended for initial or continued treatment of B12 deficiency depending on the cause and the individual with the deficiency.3

It is well documented that there is no risk of Vitamin B12 overdose.2 The body uses as much as it needs and excretes the excess through urine.
What Are Signs of Low B12?
- Fatigue and reduced strength
- Shortness of breath
