Natural Nutra Regenerage Collagen Complete

Our assessment

The evidence shows that Natural Nutra Regenerage Collagen Complete contains calcium, a mineral with a well-established role in bone health. Our assessment is that this supplement can support your skeletal system, but you need to be aware of specific safety considerations and potential medication interactions that come with calcium intake [NIH ODS].

How it works

Think of calcium as a structural building block for your bones. It supports bone density and mineral deposition, which helps keep your skeleton strong. Beyond your bones, calcium also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves send signals properly [NIH ODS].

Safety profile

Data not available for this specific product. The FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, some research suggests 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] [FDA data].

Our recommendation

We recommend you assess your total daily calcium intake from food and other supplements before adding this product. Be aware that calcium can reduce the absorption of medications including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Consult your pharmacist or doctor to check for these interactions and to determine if this supplement is right for your individual needs.
