SR SportsResearch Collagen Peptides Unflavored

Our assessment

The evidence shows that SR SportsResearch Collagen Peptides Unflavored is a supplement providing calcium, a mineral critical for bone health. However, the data we have is limited to its calcium content, and we do not have specific studies or clinical trials for this exact product. Our assessment is based on the calcium ingredient alone, and you should be aware that the full benefits of this product are not fully documented in the data provided.

How it works

Calcium works as a master regulator for your body. It supports bone mineralization by helping deposit minerals into your bone structure, and it also supports neuromuscular relaxation, meaning it helps your muscles relax and your nerves signal properly [NIH ODS]. Think of it as the key building block your body uses to keep your skeleton strong and your muscles functioning smoothly.

Safety profile

FDA received 592,059 adverse event reports across all supplement categories. For calcium specifically, side effects can include constipation, nausea, weight loss, and extreme tiredness [NIH ODS]. High calcium levels in the blood and urine may lead to poor muscle tone, poor kidney function, low phosphate levels, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Some research also suggests that 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

Start by reviewing the product label to determine the exact amount of calcium per serving, as this data is not provided. Because high calcium intake carries significant risks, do not exceed the recommended daily allowance without consulting your doctor. If you take any medications, particularly those for osteoporosis, infections, or thyroid conditions, take this supplement at least two hours apart from them to avoid absorption issues [NIH ODS]. We recommend getting your calcium levels checked by a healthcare professional before starting this supplement.

Supplement labels contain several key sections regulated by the FDA:

• Amount Per Serving — Shows the quantity of each nutrient in the product, typically in IU (International Units), mg (milligrams), or mcg (micrograms).
• % Daily Value (%DV) — Indicates how much a nutrient in a serving contributes to a daily diet. 5% DV or less is low; 20% DV or more is high.
• Other Ingredients — Lists inactive ingredients like fillers, binders, and capsule materials (e.g., gelatin, cellulose, magnesium stearate).
• Suggested Use — The manufacturer's recommended directions for taking the supplement, including timing and dosage.
