Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health and nerve function. However, the data available does not include specific studies or a complete ingredient list for Dr. David Williams Digestive Enzyme Advantage, so we must focus on the calcium component. Our assessment is that while calcium is a well-studied supplement, you should be aware of its specific risks and interactions before adding it to your routine [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton and a signaling molecule for your nerves. It supports bone mineralization, which is the process of depositing minerals into bone tissue to maintain density and strength. Additionally, it plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves transmit signals properly after they fire [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports for products in this category. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for a full product recommendation. Before taking this supplement, you should check with your healthcare provider, especially if you take any medications that interact with calcium. If you proceed, take calcium supplements separately from these medications by at least 2 hours to minimize absorption issues [NIH ODS].
