Frequently Asked Questions
Why choose B12 injections over oral supplements?
Injections bypass the digestive system entirely, delivering B12 directly to your bloodstream. Oral supplements may lose 50-90% of their potency during digestion, especially as we age and absorption decreases.
How much B12 is in each injection?
Each injection contains 1000mcg of Methylcobalamin (the most bioavailable form of B12).
How often should I inject?
Most people start with once weekly injections. Your provider may adjust based on your energy levels and lab results.
Where do I inject?
B12 is injected subcutaneously (into fatty tissue) — typically the outer thigh, abdomen, or back of the upper arm. We provide easy instructions and supplies.
Are there any side effects?
B12 injections are very well-tolerated. The most common side effect is mild soreness at the injection site. B12 is water-soluble, so excess is naturally eliminated.
Who benefits most from B12 injections?
People with fatigue, brain fog, vegetarians/vegans, those over 50 (absorption decreases with age), patients on metformin or acid blockers, and post-bariatric surgery patients.
Important Safety Information
B12 injections are generally very safe. The most common side effect is mild irritation at the injection site. B12 is water-soluble — excess amounts are naturally eliminated by the body.
Do not use if you are allergic to cobalt or cobalamin. Consult your provider if you are pregnant, breastfeeding, or have kidney disease. A licensed provider will review your health history before prescribing.
