I began using Nature's Sunshine Algin last week. My expectations were neutral, as I didn't know what to expect. I have several amalgams and would like to protect myself from mercury, but don't have overt symptoms that I can necesarily trace to this.

I've been taking 2-4 capsules daily:
Increased energy (fairly subjective, I realize)
Chronic constipation (years) gone.
Much improved eyesight! I was a three month preemie, and have ROP... only peripheral vision in my left eye, and nearsighted in my right eye.
Thankfully, it hasn't affected my quality of life, but I have residual symptoms that have
cropped up over the years. I see a retina specialist yearly.
My vision is sharper and clearer. Distance vision has improved. Colors are more vibrant.

I am incredibly thankful for these improvements. I am hoping that they continue.
I'm also going to give this supplement to my hubby and kids.
