History of vitamin D

During the Industrial Revolution (nineteenth century), an epidemic of rickets hit the city of London. In 1918, Sir Edward Mellanby showed that the disease was due to a nutritional deficiency. In the 1920s, it was discovered that cod liver oil could combat rickets. In 1922, Dr. McCollum isolated calciferol, which we named later ”vitamin D’‘. But it was not until 1924 that researchers from two American universities simultaneously discovered that sunlight was a source of vitamin D. Today , attributed the epidemic of rickets London in dense smog that covered the city at that time, depriving its people of the sun’s ultraviolet rays. The first synthesis of vitamin D was performed at Harvard in 1952 by R. B. Woodward, a scientist who received a Nobel Prize in 1965.

How to take vitamin D supplements?

weekly or monthly dosing is enough to ensure adequate intake, it is not necessary to take a daily vitamin D supplement. It is perfectly possible, provided that we choose a liquid supplement, take a weekly dose or even monthly. This is also a medical practice becoming increasingly widespread, especially among the elderly who are already taking a number of drugs on a daily basis. However, we should use vitamin D3 liquid form because it is not certain that tablets or capsules taken in large quantities dissolve properly, which would result in an insufficient dosage, part of the vitamin is excreted in the stool before metabolism. Vitamin D3 liquid is offered in counter in pharmacies and health food stores.

Many of these products, duly licensed by Health Canada, are currently accessible. We find that contain up to 1000 IU per drop. By mixing the required amount in food, it is easy to take a weekly dose (7 drops or 7000 IU) or monthly (30 drops or 30 000 IU). It is also important to choose a supplement containing only vitamin D, not a mixture of vitamin D and calcium or multivitamin supplement. The studies published to date is proof of the effectiveness and safety. In some tests, we were even given annual doses of vitamin D without having resulted in adverse effects, but it seems to be more effective to stick to a bi-monthly dosing (every 2 months) or less (monthly or weekly) to ensure constant intake.
