Going from 147 to 283 after your injections is real progress, but a daily glass of warm milk is unlikely to reliably push it past 300 on its own, since milk's
B12 content is modest and absorption depends on more than intake alone.
Next Steps
Keep other
B12 sources like eggs, fish and dairy in your diet, and check with your doctor whether a maintenance tablet makes sense at this stage.
Health Tips
A repeat blood test in a few months will tell you if diet alone is enough, so don't skip that follow-up.
