Great Product, bloodwork to prove it.

Have used this brand over 8 years. Brands vary potency which can be proved by your bloodwork, which I tried with this and three others. This was the only one that my bloodwork for D3 stayed the same over a period of 6 months. This years I raised it to 4k IU per day and for the first time my nails actually grew during the bleak northeast winters. We dont live near a Costco so I am pleased I can buy it on Amazon
