I waited for awhile to post this review. It was necessary to compare labs. After 15 months on Advanced Amino, I am convinced that it makes a significant difference in bone strength, whether one feels strong, and helps one feel more energetic and lean. I waited to receive labs so I could speak intelligently from bone results and I can report that in three tests from 2014-2020, I moved from low bone mass to right at total normalcy with the 15 months on Advanced Amino and Ultimate Bone Support. I eschewed high calcium supplements as I was more interested in protein and strontium in my vegetarian world. Voila!
