For a year now I use this product of Peak because it is inexpensive compared to other moderate dose tablets and contained 2,000 IU (50 micrograms) per day one are a good appropriate dose for me. That according to label only half a tablet to be taken daily, has to do with the legal requirements for OTC tablets that are no longer up to date will appear in the whole thing: For adults nowadays than 2,000 IU in order apply, and the individual demand could already be higher (in case of doubt can be measured by a decisive 25-OH-memory value in a specialist laboratory).
The other ingredients of the tablets are well tolerated even for people who live with food intolerances: It is dextrose (glucose) include, but not fructose and lactose, sorbitol or no gluten. Through the glucose they taste slightly sweet. For a delivery in 2013 me and the porous surface was noticed, but did not bother seriously. My pills were from the delivery date 17 months durable, so you could order now a good year's supply.
