The Vitamin Shoppe B-Complex 100
Brand: The Vitamin Shoppe · Form: TABLET [E0155]
Our assessment
The evidence shows that this product is a B-complex supplement containing a specific blend of B vitamins. For the ingredient Calcium, which is also listed, the data indicates it supports bone density and muscle relaxation [NIH ODS]. However, without complete ingredient amounts for the full B-complex, we cannot assess the potency of each individual B vitamin. Our assessment: this is a standard B-complex formulation, but you should verify your specific need for these nutrients with a healthcare provider.
How it works
Think of B vitamins as essential cofactors that help your body convert food into energy. Each B vitamin plays a distinct role, from supporting red blood cell formation to maintaining nerve function. For the calcium component, it acts as a master regulator for bone mineralization and neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, though specific report counts for this product are not available. For the calcium ingredient, safety data notes that high intakes might increase risk of heart disease and prostate cancer. High levels of calcium in the blood can cause constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data]. Calcium may also reduce absorption of certain medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available for side effects specific to the B-complex formulation itself.
Our recommendation
Start by checking your current diet and any medications you take. Because calcium can interfere with several common medications, take this supplement at a different time than those drugs. Choose a product with clearly listed amounts for each B vitamin. Discuss your individual needs with your doctor or pharmacist, especially if you are pregnant, nursing, or have a history of kidney stones or heart conditions [NIH ODS].
