Other ingredients:
calcium gluconate, blend of citric acid and magnesium carbonate which in combination with water, creates ionic magnesium citrate (quote), ascorbic acid, organic rasberry and lemon flavors, potassium citrate, organic stevia, vit D3 and boron citrate.

I use to take this a year ago and had no problems, but now, absolutely cant take it. Cost $30 and decided to try it again yesterday since it has the D3 in it and I thought I might need D3. I keep trying it occasionally since I know it is good...but I simply can not take it. Heartburn and burping ensues every time no matter how mmuch water or food I do or dont do with it.

Such a bummer. I was trying to figure out what on earth in it cause such havoc for me.
