The current recommended daily allowances for selenium are 70 micrograms (mcg) a day for men and 55 mcg a day for women. I recommend that you get at most 200 mcg a day as a supplement. That way, you probably won't overdo it.
What Are the Side Effects of Taking Selenium? The upper limit of healthy selenium intake is 400 micrograms. Side effects of too much selenium include brittle hair and nails. However, you would have to consistently consume way more than the upper limit over a long period of time before any signs of toxicity start to show.
