Quest Vitamin D 1000 IU Details
Canada's latitude is the whole argument for vitamin D supplementation. Between roughly October and April the sun does not get high enough for skin to synthesise meaningful vitamin D, no matter how long you spend outside. That is not a lifestyle problem, it is geometry, and it is why deficiency is so widespread here.
Each tablet of Quest Vitamin D3 contains 1,000 IU of vitamin D3 as cholecalciferol — the same form your skin makes and the form the body uses most efficiently, rather than the D2 that appears in some products.
Vitamin D helps in the normal development and maintenance of bones and teeth, and helps in the absorption and use of calcium and phosphorus. That absorption role matters more than it sounds: calcium supplementation without adequate vitamin D achieves far less than either does properly paired.
One tablet daily, for adults and children. Quest is a Canadian brand, manufacturing vitamins and minerals in Canada.
Who Quest Vitamin D 1000 IU Is For
This is for essentially everyone living in Canada through the winter, and particularly for anyone who works indoors, covers up outdoors, has darker skin, or is older — all of which reduce synthesis further. The dosing covers adults and children, so one bottle works for a household.
1,000 IU is a maintenance dose. If you have had bloodwork showing genuine deficiency, your practitioner may want considerably more for a period. And if you supplement calcium, taking it without vitamin D is the wrong way round.
