It will work if taken twice a day before food. along with this vitamin c should be taken for fast absorption, takes one to months to show results..will make you little gassy though.
This product will work if taken for at least 3 months. Otherwise, its not worth spending. My recommendation is to go for Solgar if you really wanna see results. Solgar starts working within a month.
I have been taking these for a month now. I wish it showed more promising results.
