The Vitamin Shoppe Vitamin B12 500 mcg

Our assessment

The evidence shows that Vitamin B12 at 500 mcg is a well-tolerated supplement for maintaining nerve health and red blood cell production. For most adults, this dose aligns with daily needs, but specific data on this exact product from The Vitamin Shoppe is limited. Data not available for clinical trials using this specific formulation.

How it works

Think of Vitamin B12 as a key metabolic worker—it helps your body convert food into energy and supports the formation of healthy red blood cells. It also plays a critical role in maintaining the myelin sheath that protects your nerves [NIH ODS].

Safety profile

FDA received 694 adverse event reports for Vitamin B12 across all products. Side effects include nausea, headache, and mild diarrhea at high doses [FDA data]. Data not available for reports specific to The Vitamin Shoppe 500 mcg product.

Our recommendation

Start with one 500 mcg tablet daily. If you are over 50, follow a vegan diet, or have a gastrointestinal condition, you may benefit from this supplement. Choose sublingual tablets for better absorption in those with absorption issues [NIH ODS].
