Review on UMZU Redwood: Natural Nitric Oxide Boosting Capsules - 30-Day Supply - Advanced N.O. Supplement for Optimal Circulatory Support by Denise Kirkeby

First off, let me say that I followed the dosing instructions exactly. After about two weeks, I started having a very bitter taste every time I ate or drank anything. About a day after the bitter taste, asthma symptoms such as shortness of breath, bronchial irritation, etc. started with me. Since it wasn't listed as a side effect I assumed something serious was going on, but the day before I went to the doctor I noticed the symptoms lessened between doses. After research, I found that if your nitric oxide levels are too high, you can develop asthma-like symptoms and a bitter taste. The good news is I don't have to self isolate, the bad news is I have half a bottle of pills that I won't be taking.
