First of all, you definitely can take too much MSM. So, be careful. Taking too much can reek havoc on your sleep patterns (keeping you up at night/giving you weird dreams), your cycle, your skin and/or your weight. Plus, you know the saying-- too much of one thing is good for nothing. That said, 1/2 teaspoon twice a day is not too much for most people. It all depends on your tolerance but here is the info I have saved regarding taking MSM as a supplement:
"Start at a low level of between 500 and 1000 mg (eighth to a quarter teaspoon) per day. Stay at that level for about a week and then add another 500 to 1000 mg per day and stay at that level for a week. Continue in the same way for several weeks never adding more than 2000 mg (half teaspoon) at one time, until you are taking between 6 and 8 teaspoons per day. This high level makes up for the years of deficiency that your body has experienced. Then reduce the amount to a maintenance level for whatever works for you. This is a balance between addressing what you want to address and being able to sleep as well as you would like at night. For most people the maintenance level is between 1 and 2 teaspoons (4000 to 8000 mg) per day. Always drink LOTS of water when starting on MSM or when increasing the amount you are taking. Also, Vit. C goes hand in hand with MSM. Supposedly, you should take 500 mcg Vit C/1000 mcg of MSM)."
I never took as much as 6 - 8 teasponns per day. I think that is too much.
Also, I take 2 silica pills (vegetal silica) per day too and that's been working out well for me (stronger hair and nails). I don't think that is too much.
