I am a new convert to the transition to being bullet proof and this was a game changer for me. I was feeling physically drained, suffering with repeat mouth ulcers, poor energy levels and thought my diet was healthy but turns out I was lacking in vital nutrients. A change from Soy milk to the Collagen Vanilla has increased my focus, and increased my energy levels immensely- I can feel this is going to be the first of many more repeat purchases of this tasty energy boosting, high quality product, by the way it is not too sweet- “Goldilocks” flavour.... just right and no need for sugar in the coffee for me, which is a ‘first’, and I cannot ‘do’ black coffee so it has been a great find, and is also a positive health booster for me, I highly recommend this product and have done to my friends. 😁
