Always reliable products, always fast delivery! Thanks, KOS!

Since I’ve been using KOS (2019), I have not once been sick, not even with a cold. I love the purity of their products and the effectiveness of their claims. I cannot imagine a life without KOS products. Customer Service is always very kind and helpful—quick in response time. Shipments could go out faster than what they do, but I have no complaints and highly recommend.

I love KOS brand greens powder and used to order from Amazon. It was incredibly simple to order direct from KOS and you get free stuff depending on how much you spend.

I’ve been enjoying KOS for about 2 years now but only recently became a subscriber. I was about to run out before my shipment. It was really easy to have my next one shipped early, and I got it in about 2 days. I’ve always loved their customer service and this is the latest example. My go to is the vanilla powder. Even the hubs loves it and he’s picky about his food.

The New Birthday Cake Protein Powder Should Be "Permanent" And Not A Limited Edition. My Favorite Flavor Thus Far!!!
