I take Anthony's Collagen. I use 2 Tablespoons to my coffee or a smoothie everyday is 11 grams of protein. It is hydrolyzed. I love it and I have been on many different brands of collagen over the years. I tried Native Path Bone Builder for the Fortibone. After about 2 months of drinking it daily, I began to have serious problem with blood in my bowel movements with every movement. Scared me badly! I contacted the Native Path Company. I sent the jars I had remaining in my order as I ordered 6 at one time. They refunded me my money. Within a couple days of stopping the product, my bowl movements returned to normal.
