FDC One Daily Multiple Vitamin
Brand: FDC · Form: TABLET [E0155] On Market
Our assessment
Our assessment: A standard multivitamin like this one can help fill nutritional gaps, but the evidence shows that the benefits are most clear for people with diagnosed deficiencies or restricted diets. The data for calcium, a key ingredient here, supports bone health, but the safety profile requires careful attention to dosing [NIH ODS]. You should not assume "more is better" with this supplement.
How it works
Think of calcium as a structural builder for your bones. It supports bone mineralization and density, and also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. This mechanism is why calcium is essential for daily function, but your body can only process a limited amount at one time.
Safety profile
The FDA has received 592,059 total adverse event reports across all supplements, but specific report counts for this product are not available. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Symptoms of excessive calcium include constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Start by reviewing your total calcium intake from food and other supplements to avoid exceeding safe levels. Take this multivitamin with food to improve absorption. If you take thyroid medication or antibiotics, separate your doses by at least two hours [NIH ODS]. For most adults, a single daily multivitamin is sufficient — do not take additional calcium supplements without consulting your healthcare provider.
