AN Amazing Nutrition Amazing Formulas Collagen Complex 1,000 mg

Our assessment

The evidence shows that this product contains calcium, a mineral with important roles in the body. However, the data regarding this specific product is very limited. We have no information on the collagen component, and the calcium claims must be evaluated carefully. Based on the available data, we cannot make a broad recommendation for this supplement without knowing the full ingredient profile.

How it works

Calcium is a master regulator for your bones and muscles. It supports bone mineralization and density, and it helps with neuromuscular relaxation and nerve signaling [NIH ODS]. Think of it as the building block that keeps your skeletal system strong and your muscles able to relax properly after contracting.

Safety profile

The FDA database contains 592,059 total adverse event reports across all supplements, but specific side effect counts for this product are not available. For calcium specifically, very high intakes can lead to poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Additionally, high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

We recommend you do not start this supplement without first consulting your doctor. The data for this specific product is incomplete, and we cannot verify the collagen content or dosage. If you are considering calcium supplementation, know that the form and dose matter greatly, and you should always check for potential interactions with any medications you take [NIH ODS]. Seek a product with a fully disclosed ingredient label and discuss your specific health needs with a healthcare professional.
