AvPak Calcium Citrate Maximum +D3
Brand: AvPak · Form: TABLET [E0155] On Market
Our assessment
Our assessment: This product provides calcium and vitamin D3, two nutrients essential for bone health. The data shows calcium supports bone density and mineralization, while vitamin D3 aids in calcium absorption [NIH ODS]. For most adults, the RDA for calcium is 1,000 to 1,200 mg daily, but you should check your total intake from food and supplements to avoid exceeding safe levels [NIH ODS].
How it works
Think of calcium as the building block for your bones and teeth. It works by supporting bone mineralization and neuromuscular relaxation, which helps your muscles relax and nerves signal properly [NIH ODS]. Vitamin D3 acts as a delivery system, helping your body absorb and use calcium effectively. Together, they maintain strong bones and support nerve and muscle function [NIH ODS].
Safety profile
The FDA has received 592,059 total adverse event reports for this product category, though this number includes all reports for the brand, not just for this specific formulation [FDA data]. Side effects from high calcium intake can include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. High calcium levels can also cause poor muscle tone, poor kidney function, and low phosphate levels [NIH ODS]. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
Our recommendation
Our recommendation: This supplement is a reasonable choice if you need to increase your calcium and vitamin D intake, especially if you have a condition affecting calcium absorption. Start with one tablet daily with food to assess tolerance. To avoid side effects, do not exceed the recommended dose on the label. If you take any of the medications listed above, separate your calcium dose by at least two hours [NIH ODS]. Consult your doctor before starting, particularly if you have a history of kidney stones, heart disease, or prostate cancer.
