BulkSupplements.com Hydrolyzed Collagen (Chicken)

Our assessment

The evidence shows that hydrolyzed collagen from chicken is a source of protein, but it is not a significant source of calcium. The data provided does not contain specific clinical studies or efficacy data for this specific product's collagen content; therefore, its specific health benefits are not confirmed by the provided data. For calcium, which is listed on the label, the data confirms it supports bone mineralization and neuromuscular relaxation [NIH ODS].

How it works

Think of calcium as a structural building block for your skeleton. It works by supporting bone density and mineral deposition, and it also plays a role in muscle relaxation and nerve signaling [NIH ODS]. However, because this product is primarily hydrolyzed collagen, the amount of calcium it provides depends entirely on the serving size listed on the label—data not available for that specific amount.

Safety profile

The FDA has received a total of 592,059 adverse event reports across all supplement categories [FDA data]. Specific to calcium, high intakes from supplements may increase the risk of heart disease and prostate cancer. Very high calcium levels can cause constipation, nausea, poor kidney function, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. Side effect reports specific to this collagen product are not available in the provided data.

Our recommendation

If you are looking to support bone health, rely on calcium from food sources or a standard calcium supplement, as the collagen in this product is not a guaranteed source of significant calcium. The data does not provide enough information to recommend this product for any specific health benefit. Discuss any new supplement with your healthcare provider, especially if you take prescription medications [NIH ODS] [FDA data].

Supplement labels contain several key sections regulated by the FDA:

• Serving Size — The recommended amount per dose. Always check this — some products require multiple capsules per serving.
• 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.
