Our assessment
The evidence shows that GNC WellBeing Be-Buff Protein & Fiber Complex Mix Vanilla Bean contains calcium as a key ingredient. Our assessment is that this product can support your bone health, but you need to be mindful of your total daily calcium intake from all sources. The data for this specific product is limited, so we rely on the well-established science of its ingredients [NIH ODS].
How it works
Think of calcium as a building block for your skeleton. It supports bone density and mineral deposition, which is crucial for keeping your bones strong as you age. Additionally, it plays a role in neuromuscular relaxation, helping your muscles and nerves signal properly [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from high levels include constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Check your total daily calcium intake from food and other supplements before adding this product. Keep your calcium intake below the upper limit of 2,000–2,500 mg per day from all sources. If you take thyroid medication or antibiotics, take this product at least two hours apart from those medications [NIH ODS].
