Meals and habits are part of the bigger picture.

Thoughtful care that works with your day.

For the movement and moments that matter to you.
Three things that matter alongside treatment.
B12 needs stomach acid, a carrier protein and a healthy lower small intestine. Metformin, long-term acid reducers, gastritis, celiac or Crohn's disease and age each interrupt that chain. Share your medicine list, and if no cause is clear, ask about testing for H. pylori and autoimmune gastritis.
B12 comes from animal foods such as clams, liver, fish, meat, poultry and eggs, plus fortified foods. If you eat mostly plants you are at higher risk, so injections work best alongside a food plan, not instead of one.
Your cells need folate as well as B12 to keep homocysteine low, so greens, legumes and other folate-rich foods help. We watch B12, methylmalonic acid and homocysteine together, because one number alone can miss a shortfall.
Share what you have been noticing, along with your diet, medicines, supplements, and health history. Your clinician considers whether testing or treatment is appropriate.

B12 may be useful when your body needs it, but taking more does not improve energy or endurance when you already get enough. Your clinician can help assess possible reasons for your symptoms.

Your health history, diet, medicines, symptoms, and any appropriate testing help guide the decision. A clinician may recommend another approach or no additional treatment.
