Longevity & Cognition

A small vitamin with an outsized role in how you function.

Vitamin B12 supports the blood, nerves and cellular processes your body relies on every day. When levels run low, the effects can show up as fatigue, weakness, difficulty concentrating or tingling.

Injectable B12 delivers cyanocobalamin directly, making it an effective way to restore B12 when your body is low or absorption is getting in the way.

Put an essential nutrient back in play.

Your body needs B12 to build healthy red blood cells, maintain normal nerve function and support the cellular processes involved in energy metabolism. Injectable B12 bypasses the digestive process, delivering it directly into the body. For people who are deficient or have difficulty absorbing enough B12, replenishment helps restore the nutrient these fundamental systems depend on.
