Vitamin B12‚ also known as cobalamin‚ is a crucial nutrient for nerve function‚ DNA synthesis‚ and red blood cell formation. While obtainable through diet‚ deficiencies are increasingly common‚ prompting many in Sri Lanka to consider supplementation. This article details B12 supplementation within the Sri Lankan context.
Why is B12 Important?
B12 plays a vital role in several bodily functions:
- Nerve Health: Maintains the myelin sheath protecting nerve fibers.

- Those with Gastrointestinal Issues: Conditions like Crohn’s disease or celiac disease.
- People taking certain medications: Proton pump inhibitors (PPIs) can reduce absorption.
