Our assessment
The evidence shows that Nature's Sunshine Collagen Unflavored contains calcium, a mineral essential for bone health. Our assessment is that while calcium is a necessary nutrient, you need to be careful about the total amount you consume from all sources, including this supplement, to avoid potential health risks [NIH ODS].
How it works
Think of calcium as a key structural component for your body. It supports bone mineralization, helping to maintain bone density and strength. It also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Very high levels in the blood 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
You should account for all calcium you get from food and other supplements when taking this product. Talk to your doctor before starting, especially if you take medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, or phenytoin, as calcium can reduce their absorption [NIH ODS]. Data on the specific collagen ingredient is not available.
