Overview
Hydrolyzed marine collagen peptide powder from Anthony's, sold as a 1 lb (16 oz) unflavored tub. Gluten free and formulated to fit paleo and keto eating patterns, aimed at anyone adding a flavorless protein source to coffee, smoothies or baking.
Marine collagen is sourced from fish rather than the bovine hide used in most collagen powders, which matters to anyone avoiding beef products or following pescatarian-adjacent diets. Being unflavored and hydrolyzed (broken into smaller peptides) means it dissolves without a strong taste or grit, so it functions more like an additive than a supplement you drink on its own.
- 16 oz hydrolyzed marine collagen powder
- Unflavored for mixing into food or drinks
- Gluten-free, paleo and keto friendly
- Marketed for bone and joint support
Who it's for
Fits people already building a daily smoothie, coffee or oatmeal routine who want to fold in an unflavored protein source without altering the taste. Less useful for anyone who wants a flavored, ready-to-drink collagen product or a vegan alternative, since marine collagen is an animal-derived ingredient.
Strengths and trade-offs
Drawn from this product's published specifications.
- Unflavored, mixes into coffee, smoothies or baking without changing taste
- Gluten free and fits paleo or keto diets
- Full pound (16 oz) tub for a supply that lasts multiple months
- Marine sourced, not suitable for vegans or vegetarians
- No flavor options if you prefer a mixed drink over a powder
Performance notes
Hydrolyzed peptides are pre-broken into smaller chains, which is the property that lets the powder dissolve into liquids rather than clump. The listing does not specify grams of collagen per serving, so buyers comparing dosage against other brands should check the label before purchase.
