## How We Tested

Our methodology: We evaluated each Collagen supplement across five criteria: ingredient purity and form, dosage per serving, third-party lab testing, brand reputation and transparency, and value for money. Products that use bioavailable forms and disclose full lab results scored highest.

Every product on this list has been verified for accurate labeling, tested for heavy metals and contaminants, and evaluated by our research team. We update this list as new products enter the market and new research becomes available.

## What to Look For in a Collagen Supplement

#### Correct Form

Not all forms of Collagen are equally effective. Look for the most bioavailable version supported by clinical research.

#### Proper Dosage

Ensure the supplement provides a clinically effective dose per serving. Underdosed products waste your money.

#### Third-Party Tested

Independent testing (NSF, USP, IFOS, or ConsumerLab) verifies what is on the label is actually in the bottle.

#### Value Per Serving

Compare price per effective dose, not just per bottle. A pricier product with higher potency can be the better deal.
