What happens when you stop taking marine collagen?

Are there any additives or extra ingredients in UNK Marine Collagen Peptides?

No. Our marine collagen peptides do not contain any additives or unnatural ingredients. Our collagen is 100% pure, fat-free, sugar-free, gluten-free, and dairy-free. We also do not use genetically modified organisms (GMOs).

Why should one choose wild-caught fish collagen over farm-raised fish collagen?

Wild-caught fish, caught from their natural habitats in the cold, fresh, pristine waters of the ocean, are free from undesirable antibiotics, hormones, and harmful contaminants. In contrast, antibiotics and other chemicals are typically used to control diseases and parasites in farm-raised fish environments. The presence of these substances in farm-raised fish collagen can have a negative effect on the purity and efficacy of the collagen product.

Can collagen help with osteoporosis and osteoarthritis?

Collagen plays an important role in bone mass. Collagen supplementation may help improve bone mass density and prevent osteoarthritis and osteoporosis.

Who should avoid marine collagen?

While marine collagen is generally safe for most people, individuals with known allergies to fish or seafood should avoid marine collagen to prevent allergic reactions. Additionally, those following a vegetarian or vegan diet may choose to avoid marine collagen due to its animal-derived source. People with specific medical conditions, such as kidney disease, liver disease, or metabolic disorders that affect amino acid metabolism, should consult with a healthcare provider before taking marine collagen.
