I'm 43 and noticed winkles forming on my neck. I was using another brand that was bovine and MCT oil. Then covid hit and now I can't get it anywhere. It's like the brand just disappeared. Odd.. So I stopped taking the collagen for awhile. Then I got to looking in the mirror and noticing that my face didn't look as tight as before and my neck as getting wrinkly. I felt like the witch from Snow White.. I didn't know there was a difference in marine collagen vs bovine other than surf or turf. I read up on it a little and decided I'd try the marine type. At first I could taste it in my coffee. I frowned when drinking it. I only use half a scoop in a 12oz mug. It's been a month now since purchasing and I don't notice any taste, only the coffee. It doesn't want to dissolve with MCT oil added. I use a milk frother to give it a quick stir and it's fine. It dissolved on its own without the MCT oil. I started noticing that my skin was looking younger just after a week of use. I will continue with the marine collagen, I think I'm having better results with this than I did with the bovine collagen. I recommend this product. Just know that you might taste it at first, and give a week or 2 to "set" in.
