  1. Richard Kennedy

    Umzu is a scam, the ads are full of lies and the products are no better than snake oil.
    You do NOT have 20 pounds of toxic poop in your colon or intestines, this is a thoroughly debunked myth. The Nitrous Oxide supplements are of dubious benefit in the manner provided and the effective dosages received from these products are unlikely to provide the benefits claimed. Additionally, their quality control is suspect (at best). Do not believe the lies that Umzu company propagates. They are the newest incarnation of the old ‘Snake Oil Salesman', but they have even less science behind them and even more lies, obfuscation, and disinformation than the classic con artists.
  2. Jeannie

    LOVE this stuff! So glad I tried it!
    Umzu Redwood is such a good product. It tastes amazing and is very easy to incorporate into my daily routine. I've shared it with a few friends and they've all ordered it to because it actually does what they say it does. Staying regular, less bloating, and definitely feel the energy boost!
