Vitamin B12 Supplements Buyer’s Guide
It’s no secret that your body requires proper nutrition in order to function correctly, and most people simply assume this means eating a healthy diet and drinking enough water. But the reality is that diet alone isn’t always sufficient for ensuring that you’re receiving the correct nutrients and vitamins you need each day, putting you at risk of serious deficiency and on-going issues that could affect your health.
From unbeatable fatigue to a compromised immune system, there are numerous indicators that could suggest that your day-to-day meals aren’t quite meeting all of your needs, and that you may need to take additional steps to fill in potential gaps. Thankfully, the market is absolutely brimming with a never-ending selection of supplements for you to take advantage of, and one quick trip to a local pharmacy will reveal shelf after shelf of different vitamins that you can start incorporating into your routine.
Why Vitamin B12 is Essential
Forms of Vitamin B12
Methylcobalamin
The natural, bioactive form of B12 that’s easily absorbed and utilized by the body. This form is particularly effective for neurological health and doesn’t require conversion.
Cyanocobalamin
The synthetic form commonly found in supplements and fortified foods. While stable and cost-effective, it requires conversion to active forms in the body.
Who Needs B12 Supplements?
♥ Vegans and Vegetarians: Plant-based diets lack natural B12 sources
♥ Adults over 50: Decreased stomach acid production affects B12 absorption
♥ People with digestive disorders: Conditions like Crohn’s disease or celiac disease
♥ Those taking certain medications: Metformin, PPIs, and other drugs can interfere with B12 absorption
