Vitamin B12 injections deliver a concentrated dose of B12 directly into the bloodstream to support energy, metabolism, red blood cell production, and healthy nervous-system function. B12 shots are a fast, simple way to correct a deficiency or top up levels for people who feel run down, foggy, or fatigued.
At R2 Medical Clinic, vitamin B12 injections are administered by our medical team at our Denver office at 1873 S Bellaire St, Ste 1215, with additional availability at our Arvada–Wheat Ridge and Castle Rock locations. B12 is often paired with our medical weight loss program. To find out if B12 injections are right for you, call (720) 640-2333.
B12 injections require a medical evaluation by a licensed provider. Individual results vary.
B12 injections may help people who experience:
Your provider reviews your symptoms and, when appropriate, lab work to confirm B12 is the right fit before starting.
Before: A brief evaluation of your symptoms, health history, and — when appropriate — B12 lab levels.
During: The injection itself takes only a moment and is given by our medical team in-office.
After: You can return to normal activities immediately. Many patients begin their program with weekly injections and transition to a maintenance schedule as levels stabilize.

Vitamin B12 supports energy production, red blood cell formation, nervous-system function, and metabolism. People with low B12 or absorption issues often report improved energy and mental clarity once levels are restored. B12 is also commonly used alongside a physician-supervised weight-loss program.
It depends on your B12 levels, symptoms, and goals. Many patients start with weekly injections and move to a maintenance schedule once levels normalize. Your provider recommends a cadence based on lab results.
For people with absorption problems, injections deliver B12 directly into the bloodstream and bypass the digestive tract, which can be more reliable than oral tablets. Your provider will help you decide which route fits your needs.
