I have been taking 2g Protelos daily for about 6 weeks. During the last week I have had problems with glare, from lights in shops, PC screen, and when I was painting a wall white. The reaction I get is my vision becomes progressively more blurred from the edges, until I can see nothing clearly and at the same time I become nauseated. The symptoms gradually clear when I am not looking at anything bright.
I don't want to blame these symptoms on the Protelos if they are caused by something else, as I am so delighted to have discovered something that will strengthen my very fragile bones that doesn't make me ill after so many years.
Has anyone suffered any similar symptoms?


Hi Oakside
Protelos has aspartame added to strontium ranelate. Aspartame is very unhealthy for the brain and nervous system. So, it could be the side effects of the aspartame. Many people will not take protelos because it contains aspartame. I think patients should demand it be removed from an otherwise great formula. Also, vision changes with age. I am 57 and I notice that I have recently lost a considerable amount of my peripheral vision; and my vision fluctuates between cloudy and clear. All of these changes have occurred in the past year. So, I would tend to attribute these effects to age; if you are in your 50s or older. If not, it might be an allergic reaction. I would check with a doctor. You can switch to Strontium Citrate that does not have aspartame and do a case/control study. If you symptoms disappear on SC then it could be the aspartame.
