Great Collagen Quality

CodeAge Wild Caught Biotin Marine Collagen is great quality. It has pure ingredients. The dosage is 4 capsules of no taste which is a lot of one supplement to take. But if that is the amount I been using 4 a day. Not so easy to consume 4 of one. This has been helping my hair, nails and knee and elbow joints be stronger. I have felt and seen a lot of improvement taking this supplement. It has great benefits with its composition. With my age getting older this helps with my diet and exercise. They come in a wide mouth package container, easy to get the supplements out. It's a great product totally.

High quality of collagen

Verified purchase

I tried this supplement as additional collagen intake for my body. It is easily to consume especially if you are not a fan of fish. I don’t see any significant results since I also taking natural collagen from bone broth and salmons into my diet.

Noticeable Results and High Quality!

Verified purchase

I’ve been taking this supplement for several weeks and already notice an improvement in my skin elasticity and hair strength. The combination of marine collagen and biotin is powerful — it feels clean and effective. At my age, maintaining skin and joint health is essential, and this formula truly supports that. No fishy aftertaste, and the ingredient list is impressive. Great quality and composition — highly recommend for anyone looking to support beauty from within!
