Yes! I use this product. One of my closest friends from college represents them so she got me into it. I wouldn't say I see a ton of physical results, like hair/skin or faster healing. But I will tell you I can feel a difference energy wise when I don't take it, especially during my workouts.
The stuff is also great for kids - I get the chewables and not the pills. It was just too many pills, even for an adult to take in my opinion, and I found I wasn't using it in that form because I just hated swallowing them. Plus, as I said, the chewables work for kids. I don't give them to my youngest yet, who is 2, but my oldest who is 5 takes 2 of each (fruit/veggie) in the mornings with breakfast and she loves them. We call them her "vitamins" and I feel good knowing she is getting some veggies in her at breakfast time.
One other note, as an adult, I take only half of what is recommended. I found that if I took the full dosage (8 chewables a day, 4 of each), I was way too gassy! Cutting it in half resolved that issue but still made me feel like I was getting the benefits. Plus it lasts twice as long! A good thing, given how expensive the stuff can be.
Hope this helps!
