B12 Tablets vs. Injections: Experts Debate Effectiveness
Two doctors are discussing whether B12 tablets or injections are better.
Dr. Sanghavi says tablets can give false positive results because they stay in the body for a short time and might not show the real effect.
Dr. Ugalmugle disagrees and says that B12 tests measure both active and inactive forms, so some people might still feel deficient even if their test results are normal.
Both doctors have different opinions on how to best treat B12 deficiency.
Dr. Amir Sanghavi claims B12 tablets can give false positive results compared to injections.
B12 tablets remain in the body for 24-48 hours, potentially affecting test accuracy.
Dr. Rituja Ugalmugle argues that B12 tests measure total B12, including inactive forms.
Symptoms of B12 deficiency may persist even with normal test results due to inactive B12.
Experts debate the best method for treating and testing B12 deficiency.
