Query: Some side affects

I purchased this product based on reviews that were very helpful and the value of the product is the best I've seen. I have been taking them for 3 weeks now. I started with 2 a day and started having problems with gas. I went down to one a day with another supplement that I like and no meal with it and solved the gas problem that way. Soy is known for not agreeing with people so its not the brand. I would recomend this product because of the value for the money and it has helped tremendously with the hot flashes.
