It might be the sugar but I always feel good after taking these
In fact they're a bit addictive. I was eating them like lollies. I had to stop taking them as I read that you should take breaks from echinacea and not take it all the time. Love the C and D combination. Flavour is nice. The only negative for me is the fructose gives me flatulence within minutes of taking them and I'm concerned about the sugar content.
It would be helpful if the label would include the grams of sugar and calories per pill. They are very sweet and I would like to know how much sugar I am eating,
