re: Could Celsius cause Gout flare ups?

The only thing I see in the celsius that could cause a problem is niacin. If you have high niacin levels that will build excess uric acid.

Keep in mind that there are 2 reasons for gout. Either your purine intake is to high or your body isn't flushing the uric acid out properly.

I couldn't take allopurinol due to side effects but since I started drinking a lot of water daily and consume nothing with high fructose corn syrup I haven't had a flare in almost 2 years.

As others have stated you gotta get it under control or you are gonna destroy your joints.
