Sports Research Marine Collagen Peptides Powder - Sourced from Wild-Caught Fish Pescatarian Friendly Keto Certified Non-GMO Tested -

This is my favorite collagen because it is marine based and I prefer that over bovine ones. It is a bit hard to dissolve in water so I recommend adding to a smoothie if you can. It is great for the skin and overall collagen support, it is pricey but this company is well known and I think their products are good. It doest have a strong fish taste like other marine based collagen products do and I like that. It helps my skin and gut health so I use it as a part of my regular supplements. Read more

I’ve been consistently using the Sports Research Marine Collagen and I’m genuinely impressed with the quality. The powder is very fine and dissolves easily in my drinks without leaving clumps or a strong aftertaste. After a few weeks of use, I’ve noticed my skin looking more hydrated and my hair and nails feeling stronger. What I really love is how light it feels on my stomach — no bloating or discomfort at all. I usually mix it into my morning coffee or smoothies, and it blends perfectly every time. The ingredients are clean and the brand feels very trustworthy, which is important to me when choosing supplements. This has definitely become a staple in my daily wellness routine. Highly recommend if you’re looking for a high-quality marine collagen! Read more

Love this brand! This collagen is so good! Dissolves easily in hot and cool liquids! No flavor has no flavor and no bad after tastes! It definitely helps with joint pain!! Read more

While I don't think it has a fishy smell or taste, it does slightly alter the taste of what ever you mix it into. I tried it mixed into a glass with a strawberry watermelon flavor packet and water, stirred to mix and then added ice. It just tasted less sweet, but not fishy. The second time, I mixed it into a room-temp 8 oz bottle of Gatorade Zero (grape flavored). Same thing as before, it just tasted less sweet. Both times I used 1 Tablespoon of the collagen and not the included scoop (because it was all the way at the bottom and I didn't want to fish it out (no pun intended); and each time the collagen dissolved with no issues. With that being said, I probably will not be adding this to my morning coffee, and stick with mixing it into a fruity type of drink. I have only used this product twice, so I cannot say how or if it has improved my skin, hair or nails. ----------------------------------------------- Updated Aug. 31, 2025: I have used this product off and on since the original review. Still most of the container left. It still mixes well into water, and does not have a fishy taste. Still not brave enough to try in my morning coffee. I haven't noticed a considerable difference in my hair, but I have been using new hair care products & men's rogaine so there is that helping. I have set a timer in my phone, so I can remember to take this every day to really see if it helps before ordering another tub. Read more

Great product. Ever since taking one scoop daily I see a big improvement in my hair growth. Mixes great. Read more

I don’t know how anyone could say this has a fishy smell or taste. It’s completely neutral. I use the unflavored version in my green smoothies with flaxseed and avocado. Absolutely delicious with no bad taste or grainy texture. Read more

*Update to review 3/10/26. The company contacted me and wanted to make things right. I appreciate that. My money was refunded. I normally purchase a different brand of collagen but I wanted to try a cheaper brand. This does not blend well with coffee. There were some weird brown specks in my coffee. Once added you can smell it and it smells terrible. They use types of fish that you don’t typically see in marine collagen. I have never heard of a barramundi fish. I have noticed my body has developed a smell(lower region) after using this a few days. I won’t purchase again. Read more

Best marine collagen I’ve found. It mixes well in smoothies. My hair and joints have improved since taking it. Read more
