The Mayo Clinic & Harvard Health Review both recommend 600 iu of D3 as the standard dose. This is 8 TIMES that which is borderline negligent for an “Amazon Elements” “just grab this one” supplement, especially since (according to Harvard Health) "More is not necessarily better. In fact, more can be worse. A 2010 study published in JAMA showed that intake of very high doses of vitamin D (above 4000 iu) in older women was associated with more falls and fractures.” This pill is 5000 iu! An amount that you should only take if you have conferred with your doctor!
YES, this is one of those reviews where I have to admit my own stupidity: I‘m new to D3 and didn't check standard dosage before purchasing. I was lulled into a false sense of security by the standard looking packaging. Two days after beginning to take the supplement, I stopped being able to sleep at night. It took me until 4 AM to go to sleep. at 4 AM, when I was trying to figure out what the heck was going on, I googled “vitamin D supplement unable to sleep“ and yes, it turns out that a very high dosage of vitamin D can inhibit sleep. And yes, this pill qualifies as a very high dosage. This is ironic since part of my reason for taking D3 is because of a New York Times article I recently read about how D3 can improve sleep quality.
Yes, it's ridiculous that I started to take a supplement without double checking the dosage. That was incredibly stupid of me. But! An Amazon Elements Supplement shouldn't be a dangerously high dose. That's just weird. This review is to draw attention to that
