Pure Encapsulations Calcium with Vitamin D3
Brand: Pure Encapsulations · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that calcium is a foundational mineral for bone health, and this product combines it with vitamin D3 to support absorption. For most adults, meeting the recommended intake of 1,000 mg of calcium daily is achievable through diet, but supplementation can fill gaps [NIH ODS].
How it works
Think of calcium as the building block for your skeleton — it supports bone mineralization and density. It also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received 592,059 adverse event reports for products containing calcium. High intakes may increase the risk of heart disease and prostate cancer. Excess calcium in the blood or urine can cause constipation, nausea, weight loss, extreme tiredness, frequent urination, and abnormal heart rhythms [NIH ODS] [FDA data].
Our recommendation
Start by assessing your dietary calcium intake from dairy, leafy greens, and fortified foods. If you take a supplement, avoid exceeding 2,000 mg total daily from all sources. Take this product with food and separate from medications like thyroid hormone or antibiotics by at least 2 hours [NIH ODS].
