The Vitamin Shoppe B-Complex 50
Brand: The Vitamin Shoppe · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that B-complex vitamins are essential for energy metabolism and nervous system function, but the specific formulation in The Vitamin Shoppe B-Complex 50 includes calcium, which requires careful consideration. Our assessment is that this product may benefit individuals with known B-vitamin deficiencies, but you should be aware that calcium can interfere with several medications and may carry risks at high intakes [NIH ODS].
How it works
Think of B vitamins as a team of cellular helpers that convert food into usable energy. The included calcium supports bone mineralization and neuromuscular relaxation, acting as a master regulator for bone density and muscle signaling [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports for products in this category. Specific side effects for calcium from the data include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease at very high levels [FDA data] [NIH ODS]. Calcium can also reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data for other B-vitamin-specific side effects in this product is not available.
Our recommendation
Start by checking with your doctor if you take any medications listed above, as calcium may interfere with them. For most people, a standard B-complex without added minerals is sufficient. If you choose this product, take it with food and separate it from other medications by at least two hours [NIH ODS].
