Bests & Worsts Reviews from Amazon

This is my first review on Amazon. This collagen is the best deal you can find so far!!! :-) I previously used: 1) Vital Proteins Pasture-Raised, Grass-Fed Collagen Peptides 2) Premium Collagen Peptides Grass-Fed, Pasture Raised 3) Root Vitality Collagen Powder, Collagen Peptides, Grass Fed, Pasture Raised 4) And finally this one by Zen Principle. The first thing is that all four lack proper third party certifications to guarantee their claims in quality (e.g. grass-fed, pasture-raised, no added hormones, no antibiotics, non-gmo, etc.). However, most of the cattle they used are from Brazil, Argentina and Uruguay. With that said, the majority of the cattle (with significant exceptions!) in these places are treated in better environments than cattle from the USA. Therefore, with the lack of third party certifications in the 99% of collagen supplements you need to relied on the good faith of these companies. So, in terms of what they claim, all claimed the same quality standards with no support on their claims by third party certifications. That means that we as consumers need to trust the quality claims or don't buy the product at all. In that regards, all are the same! Further on, in terms of flavor (flavorless) and texture I can tell you all four are the same thing. Still further, if you want to use the collagen with water and/or coffee/juice I advised you to try Premium Collagen Peptides and then try this one. Vital Proteins is the best when mixing in water, coffee and juice but is ridiculously expensive for what it is. However, if you use your collagen in your smoothie like me, ALL FOUR ARE THE SAME!!!! Trust me!!! ;-) This one is the cheapest of all four!!! Finally, a) In terms of quality claims (non-gmo, grass-fed, no hormones, etc.) all four are the same. b) In terms of flavor, texture all four are the same. c) For coffee, water, and juice this is not the best of all four (please see above) but it does the work if your not too picky. d) For smoothies, ALL FOUR ARE THE SAME!!! e) This one is the cheapest one!!! That's my reasoning for giving this product 5 stars!!! Good luck!!!!
