ProCaps Laboratories Vitamin D3 1000
Brand: ProCaps Laboratories · Form: CAPSULE [E0159]
Our assessment
Our assessment: The evidence shows that this product provides 1000 IU of vitamin D3, which is above the standard 600 IU RDA for most adults. Vitamin D supports bone health by aiding calcium absorption and plays a role in immune function [NIH ODS]. For calcium specifically, the data confirms its role in bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of vitamin D as a master regulator — it helps your body absorb calcium to maintain strong bones and supports nerve signaling for muscle function [NIH ODS]. Calcium itself works by supporting bone density and mineral deposition, as well as promoting muscle relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplement categories. For calcium, specific risks include that 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Start at 1000 IU daily. Have your blood levels checked to ensure you are not exceeding safe ranges. Be mindful of total calcium intake from all sources, including food and other supplements, to avoid the risks associated with high levels [NIH ODS] [FDA data].
