What is Methylcobalamin B12?

B12 is a vitamin your body needs every day but can’t make on its own. Methylcobalamin is the most natural form, which your body uses it right away without any conversion. It helps your energy, brain, mood, nerves, and heart.

Most people don’t get enough, especially as they get older, and even with B12 pills a lot gets lost in your stomach before reaching your cells. An injection skips all of that and delivers a full dose straight into your bloodstream.

At Ness, we partner only with trusted, licensed U.S. pharmacies to ensure safe, reliable care.

$100/month for 10 mL
$125/month for 20 mL

Your care team will find the right plan for you, and pricing may vary depending on your personal treatment needs.

How do I take Methylcobalamin B12?

You give yourself a small injection under the skin (usually in your belly or thigh) once a night before bed. The needle is very small, and most people say it barely hurts.

Please refer to our educational videos for How-To for guidance on subcutaneous injection. If you have any questions, our support team is available to assist you.

Is Methylcobalamin B12 safe and FDA-approved?

B12 is one of the safest things you can put in your body. It’s a vitamin you already need every single day. Injectable B12 has been used safely by doctors for decades and is one of the most common medical injections out there.

It’s available at Ness as a compounded medication made by a licensed U.S. pharmacy and prescribed by a real doctor.

The best part? B12 is water-soluble, which means your body naturally flushes out anything it doesn’t need so there’s no risk of taking too much.

At Ness, a licensed clinician checks your health before prescribing and stays in touch with you throughout your treatment.
