FAQs

Why should I choose an injection over an OTC supplement?

Injections have better bioavailability than oral supplements as they bypass the digestive system completely, providing a direct supply of B12 into the bloodstream to fuel your body. Oral supplements might work for some, however, as we age, our ability to break down oral supplements often decreases.

How often do I administer the injections?

Start by injecting 1ml/cc per injection once per week. If you feel you’re not getting your expected results, please contact your prescriber.

How can B12 shots help with longevity?

B12 shots aren’t just a great way to enjoy more energy throughout the day. In fact, B12 shots can also improve our cognitive function, maintain our vision, and lower our risk for age-related conditions like osteoporosis, macular degeneration, and cardiovascular disease. B12 shots also help us to look as good as we feel by promoting better sleep and healthier skin and nails.
