I really like this collagen. I was previously taking one that was made from bovine hide, and there was definitely an aftertaste. This one genuinely has no aftertaste. I don’t know that I can say at this point how or if it’s improving my skin (my main reason for taking it; my hair and nails or ok). I’m 51, and although I use excellent skincare products, avoid the sun and drink plenty of water, I’m through menopause. And any product or supplement is going to have a lot of heavy lifting to do on post-menopausal skin. It’s just the way of things. Taking into consideration the other product I was using, I’ve now been using collagen supplements for several months and I honestly don’t see that much difference. Maybe a younger person would see more immediate effects. However, I’m going to keep taking holi(mane) to see if it’s beneficial. I do wish it dissolved a bit easier. It mixes in great if you use a milk frother, but if you are just stirring with a spoon, it can take some time/tend to clump. I also really hate these bags that many companies tend to use. Obviously that’s not a gripe about the product. But what I have noticed is that over time, the dust of the product gets in the resealable portion, and it doesn’t want to stay closed any longer. I also can’t imagine that these bags are very good for the environment. I do think this is worth trying if you are interested in collagen. It’s a quality product.
