Irwin Naturals Collagen-Pure
Brand: Irwin Naturals · Form: SOFTGEL CAPSULE [E0161] On Market
Our assessment
The evidence shows that Irwin Naturals Collagen-Pure contains calcium as a key ingredient, but the data we have covers calcium, not the collagen itself. For calcium, our assessment is that it supports bone density and nerve signaling, but you need to be aware of specific risks and medication interactions [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton and a signal conductor for your nerves. It works through bone mineralization to support bone density and mineral deposition, and it supports neuromuscular relaxation, helping your muscles relax and nerves signal properly [NIH ODS].
Safety profile
Total FDA adverse event reports for all supplements in the database is 592,059, but specific data for this product is not available. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High calcium levels 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].
Our recommendation
Before starting this product, check your total calcium intake from food and other supplements to avoid exceeding safe levels. If you take bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, or phenytoin, separate your calcium dose by at least two hours because calcium can reduce the absorption of these medications [NIH ODS]. Consult your healthcare provider to determine if this supplement is right for you.
