This product is easy to take and has such a mild flavour. It has definitely helped with my digestive and overall health.
This product is a mainstay for me due to some serious gut issues. Combined with other supps It has supported me in balancing my gut by acting in a way that it overcrowds bad bacteria. It is a very high-quality product known to reduce E. coli. It tastes great and is easy to take because of this.
Had a gut test and these were recommended to take, would buy again and noticed a difference.
I use this every morning with Byan Johnson's longevity mix plus collagen and my digestion has considerably improved!
I use this daily, half a teaspoon as part of the blue print protocol for 6 months now and I've notice my digestion is smooth and predictable. I can feel the difference when I stopped taking it.
