Review: good product - great
Review: Well, Its works. Just need to work on dosage. I clearly went Overboard. - Went from 26 on my blood test to 50 to now 150, over the course of 9 months while adjusting the dosage up and up and up. Yup, it works. Now I am technically on the "Toxic" / overdose side of the scale but don't have any issues. I highly recommend This product. Just make sure to also get a good cheap scale and measure out what the daily dose is and multiply it as needed. and of course, get blood work done every 4 months or so to see where you are. Technically speaking, I believe this is something you could theoretically calculate before hand and fix your deficiency with a single dose. But experimenting with low dosages lets you find what exactly is it that you need the daily dose to be for your given life style. I am Happy. and my neck no longer hurts (it stop hurting within like 2 months of taking this). and yes, I am taking a break from this product for a bit until my levels come below 100. Then I will start up again. I was doing something like 12-16 x the amount found in AG1's daily D3 drop dose the last 3 or 4 months. I would forget to take it some days though.

### ⭐⭐⭐⭐⭐ perfect--and incredibly affordable!
*by F***A on April 19, 2014*

I bought the 250 g (8.82 oz) size and a "smart weigh GEM20 digital jewelry scale" to weigh out the tiny amount needed for a dose. The package gives a serving size of 46 milligrams (easy to weigh on my newly calibrated scale). 46 mg equals 5000 IU, which is more than my doctor recommended, so I cut it in half to 23 mg per serving, and have it once a day. The servings per 250 g? For 5000 IU, that would be 5434 servings. Double that for 2500 IU. At $24, this comes out to approximately 2/10s of a penny per serving. :-) If it wouldn't eventually degrade, I wouldn't have to buy more for nearly 15 years, given that both I and my daughter are taking it. I am sharing it with friends, so that it all gets used. :-) Beyond the price, which I really, really appreciate, I like this because it doesn't have "fillers." My daughter is always manifesting new food allergies and intolerances, the latest of which is to stearic acid and magnesium stearate. When you realize what a tiny amount of powder constitutes 2500 IU, you will see that the capsules are mostly filler. Now my daughter can safely take Vitamin D3 again. The package does warn "Potentially toxic in higher quantities." If you do not have a scale capable of accurately measuring .001 g, you will need to buy one in order to safely use this product. In addition, it is important to balance vitamin D with Vitamin A: food sources are best for A, so some liver or salmon once or twice a week.
