- Raspberry ketones - side-effect of red face, face muscle twitching
Whenever I use Raspberry Ketones 500mg capsules (1 a day) I get reddening of the tops of my cheeks coupled with muscle tightening/twitching of the cheek muscles closest to the nose (the muscles that contract if someone blows in your eyes) and the muscles at the bridge of nose at times too. Both sets of symptoms last for a day, then to be repeated again the next day on taking the next capsule. Whenever I cease using the product the symptoms likewise end. They began occurring from the very first use of the product. They are sometimes accompanied by a very low-grade headache. I thus now no longer use the product, plus the product made no difference whatsoever to my weight gain/loss when using it daily over several weeks.

Comments from related studies:
From this study (4 months ago):
I have been in pain and have suffered for over 7 years with muscle pain with cramping, aching, burning, stinging, pins/needles, weakness, numbness and paralysis, etc. I live with fatigue and utter exhaustion everyday and hate having to take medicine period, but have no choice in the matter. I know that this is something serious..I can feel it. I just have to get the Doctors, to find it...and fix whatever it is that is wrong.
I am trying to find what is the root cause of it all, then I might be able to find some relief.."Lord Willing". I have always been a driven individual and love life. I am a fighter and a survivor, so I will continue forward..until I find a way to the answer.
The pain level stays around 5 or 6 everyday and can be overwhelming at times, but I pray and I find relief for a moment..from The Lord. Grateful to be alive. Just want life to be normal again and to be able, to spend my time with my family that I have missed so much of.
