Thank you for a fantastic product!! I am a veterinarian and all four of my dogs are on your collagen products. My one dog has had chronic joint problems since he was young so he is on the advanced formulation, and it has done wonders for him! My other three dogs are all on the maintenance formulation, to keep them healthy and mobile for as long as possible! Natural supplements are definitely the way to go and this is exactly what I was looking for for my pets. And knowing it's all human-grade ingredients gives a lot of peace of mind!

We just love this product! My 13-year-old Jack Russell is a fussy eater but loves this mixed with water and poured over his food. In just 2 weeks I have seen such a difference in him. Despite an old paw injury, he is so much more active and obviously feels much better. If he is happy. I am happy! Even his coat feels softer. I highly recommend NutriFlex™ and won't be without it!
