How Vitamin B12 Fuels Your Body
Vitamin B12, also known as cobalamin, is a crucial nutrient that helps your body convert food into energy. It plays a key role in red blood cell formation, nerve function, and DNA synthesis. Without enough B12, you may experience fatigue, weakness, and even neurological issues.
The Link Between Vitamin B12 and Weight Loss
While B12 itself doesn't directly cause weight loss, a deficiency can slow down your metabolism and reduce energy levels, making it harder to stay active and burn calories. Some studies suggest that adequate B12 levels may help regulate fat metabolism and support a healthy weight when combined with proper diet and exercise.
Best Food Sources of Vitamin B12
Animal products are the richest sources of B12. These include:
- Beef liver and other organ meats
- Fish like salmon and tuna
- Eggs and dairy products
- Fortified cereals (for vegetarians/vegans)
Signs You Might Need More Vitamin B12
Watch for these common deficiency symptoms:
- Persistent fatigue and weakness
- Tingling in hands or feet
- Memory problems or brain fog
- Pale or yellowish skin
Should You Consider B12 Supplements?

- Vegans and vegetarians
- Older adults with reduced absorption
