How does a B12 injection work?

B12 injections deliver methylcobalamin directly into your bloodstream, bypassing digestion for maximum absorption. This supports energy production, mood regulation, and red blood cell formation more effectively than oral supplements.

We use methylcobalamin, a bioavailable and highly absorbable form of B12. It’s the preferred option for those looking for optimal cellular support, energy, and brain function.

Anyone experiencing fatigue, brain fog, low mood, or a plant-based diet may benefit. B12 injections are also ideal for those with absorption issues or low B12 levels due to age or medications.

Most people start with one injection per week and adjust based on their provider’s guidance and individual needs. Our team offers free consultations to help personalize your plan.

B12 injections are generally well tolerated. Mild side effects are rare but may include slight soreness at the injection site or a temporary feeling of warmth.

B12 is often safe to take alongside most supplements and medications – however, always check with your provider first. It may even enhance the effects of other wellness treatments by supporting mitochondrial function and overall energy levels. ZestRx providers will review your current medications and health history before dispensing.
