what makes marine collagen special?

Our collagen is harvested from wild-caught, cold-water fish in the clean North Atlantic waters of Nova Scotia, Canada. Unlike farm-raised or bovine collagen, it’s naturally pure, highly bioavailable (<3 kDa peptides), and free from antibiotics, hormones, and additives. With all four major collagen types, it delivers full-spectrum support for skin, joints, bones, and muscle recovery — all in a neutral-tasting, easy-to-mix powder.

Best Collagen

I have been taking Collagen for years. This is by far the best product you can get. Highly recommend

Highly recommend

Highly recommend. Dissolves easily and no after taste. Joints feel better and my skin is soft and glowing. Nails are growing stronger again. Love the new packaging also.

This product is really great

This product is really great. I take it every day and really feel the difference. My joints don't hurt as much or make popping sounds all the time. Also, I'm glad that the packaging changed to a can shape. It's easier to scoop out, and less messy.

Amazinggg

By far the best collagen I’ve had! I put it in my coffee every morning and can’t even taste it! Highly recommend to anyone looking for a high quality product and great customer service!

Glad I switched from my former collagen powder

My star rating is a tad conservative here b/c I've only been using this for 20 days. But I already ordered another one. That being said . . .

I had been using a different one for about 7 months. But things about that one really bugged me. The first one I ordered came in a bigger container (more in there). Then the container shrank. Then the doasage increased (3 to 4 Tbsp). The powder didn't disolve. Apparently, only in hot liquids it works but I can't drink hot liquids. So, mfr said I had to to microwave my cold liquid. Put the powder in. WAIT. And I do mean WAIT until the powder disolved. Then I could chill it with ice cubes. Truly a pain. PLUS, it had this REALLY SWEET taste. And no scooper. It just seemed fishy (pardon my pun). Eventually, I learned this company was bought out by NESTLE. Can't tell you for sure, but I suspect there are all kinds of fillers in that stuff. Increased prices; increased doses, smaller quantities.

I learned about this one. Here's what I like on the practical side. It has a scooper. Only 1 tbsp. Zip Loc packaging (had an issue about it later but not a big deal). And it DESOLVES!!! I don't have to heat it or anything. In fact, heating is a bad idea. It did weird stuff. Not important.

All I do now is put the scoop at the bottom of my glass and fill with my cold drink. The stuff dissolves pretty quickly. Only thing I don't like about the ziploc bag is that the powder kind of sticks to the sides (like static cling), and I do get remnants of the white stuff on my hands. Mildly annoying. But there's the provided scoop, and I just put the powder into a tupperware-type of container. Problem solved.

I'm pretty sure that this powder has more types of collagen than my previous one. But it wouldn't be fair for me to say if it's more effective this early in the game.
