Methodology v3.1 (updated 8 Oct 2026) — what changed

This supplement provides two forms of collagen, which are beneficial for connective tissue health. The inclusion of Vitamin E and Biotin supports skin, hair, and nail health. While generally well-tolerated, individuals with allergies to chicken or marine products should exercise caution. The product does not list any independent third-party certifications for banned substances, which is a common expectation for sports-related supplements.

Collagen supplement with added vitamins for skin and joint support

This supplement features both marine and chicken collagen, along with Vitamin E and Biotin, which are beneficial for joint health, skin elasticity, and hair and nail strength. It is generally safe for most adults, but those with specific allergies to fish or poultry should check for adverse reactions. The product does not carry an independent certification for banned substances, which may be a consideration for athletes.

Okay for: Healthy adults seeking collagen supplementation

Claim check

Front-of-pack marketing claims checked against this product's actual ingredients and nutrition. "Can't verify" means the label does not provide enough information to check the claim — it is not the same as the claim being false.

?
"SUPPORTS HEALTHY JOINTS & BONES" Can't verify

The claim of supporting healthy joints and bones is a health benefit that cannot be verified from the ingredient list or nutrition information alone.

?
"SUPPORTS HEALTHY HAIR, SKIN, & NAILS" Can't verify

The claim of supporting healthy hair, skin, and nails is a health benefit that cannot be verified from the ingredient list or nutrition information alone.

?
"WITH 100% RDA OF BIOTIN & VITAMIN E" Can't verify

While D-Biotin and DL-alpha-tocopheryl Acetate (Vitamin E) are listed, the label does not state the percentage of the Recommended Dietary Allowance (RDA) for these vitamins, so the 100% RDA claim cannot be confirmed.

D-Biotin DL-alpha-tocopheryl Acetate Vitamin E 83 mg (per 100g)

"GLUTEN & LACTOSE-FREE" Can't verify

The label does not provide information about gluten or lactose content, so this claim cannot be verified.

About this analysis: Based on declared label information and available evidence. Decode Label does not independently laboratory-test products, and a score is not a regulatory determination or medical advice.

Disclaimer: Safety scores are Decode Label-generated assessments based on publicly available regulatory data (FSSAI, WHO, EFSA, IARC) and peer-reviewed research. They are not a substitute for professional medical advice, and they are not a regulatory determination, a laboratory safety certification or a medical diagnosis. Ingredient safety can vary by individual health conditions, concentration, and usage context. Decode Label is an independent information service and scores every brand by the same rules. No brand pays for or influences its score. Our founder also founded the personal-care brand Botani Bestie (see our story); its products are scored exactly like everyone else's. Data limitations: This assessment is based on the information declared on the product label and the evidence sources above — Decode Label does not independently laboratory-test this product. Ingredient concentrations, sourcing and manufacturing can vary between batches and are not always disclosed. A finding that is not shown here means it was not identified from the available label information, not that it has been ruled out.
