GNC Vitamin B-12 is a 500 mcg tablet supplement designed to support energy production and carbohydrate metabolism, with 100 tablets per bottle.
Vitamin B-12 is an essential nutrient for carbohydrate metabolism and energy production, and it is required for red blood cell formation. GNC Vitamin B-12 brings that nutrient into a tablet format for people looking for a clearly identified B-12 supplement. Its stated role is nutritional support; the product details do not establish a guaranteed personal result, so the practical choice is based on the ingredient, tablet strength, count, and formula characteristics.
GNC Vitamin B-12 is formulated to support energy production and carbohydrate metabolism. Vitamin B-12 is also required for red blood cell formation, giving the nutrient a role beyond the energy-support purpose highlighted for this product. These are nutrient functions, not a promise that every person will experience a particular change.
Each tablet contains 500 mcg of vitamin B-12, and the bottle contains 100 tablets. The per-tablet amount and total count make it straightforward to identify the product format when comparing B-12 supplements. The product is presented as tablets rather than a liquid or powder.
GNC Vitamin B-12 is kosher and gluten free. Its formula has no artificial colors, artificial flavors, preservatives, wheat, soy, dairy, or sodium, which gives shoppers specific ingredient and dietary details to consider.

Its listed dietary and formula characteristics make those details easy to assess alongside the intended nutrient support.
