Sunshine in a capsule.

All vitamins are important to our health and vitamin D is no different, but with an estimated 1 billion people in the world suffering from low levels, supplements are a must for many of us.
What’s more, the darker your skin pigmentation, the more likely you’ll suffer from low vitamin D in cloudy climates, and even the lightest skin struggles to get enough of the sunshine vitamin in winter.
Subscribe to get your vitamin D online from Treated and we can help you avoid low vitamin D levels with monthly deliveries. You can also get Colekal D3 sent to you every three months, if you find that more convenient.
Colekal D3 is a form of vitamin D, but to understand its importance, we need to know what vitamin D is.
Vitamin D is an essential vitamin, one that we cannot live without. It plays a major role in keeping our muscles, bones and teeth healthy and low levels of it are linked to everything from depression to cancer.
Vitamin D can be acquired from exposing the skin to sunlight (in fact we get the majority of our vitamin D from the sun). In dark winter months this can become much harder, which is where Colekal D3 comes in.
Colekal D3 works by increasing the amount of Vitamin D3 (colecalciferol) in your body. Vitamin D helps to support your body’s function by increasing your levels of calcium and phosphate. It is available in different dosages, the smallest of which are used to prevent levels of vitamin D dropping to a degree that might impact your health.
But Colekal isn’t just for prevention. It can also help to treat severe deficiencies that can lead to serious bone conditions. In these cases you’ll likely need a prescription for the higher doses of Colekal, which are taken over a number of weeks.
There are different dosages of Colekal that include over the counter supplements and high dosage prescription medications.
The most common supplement strength product is Colekal D3 800 IU (IU is the measurement of supplement potency) capsules, tablets and effervescents. 400 and 1,000 IU tablets are also taken daily.
For treatments, dosages range from 3,200 to 20,000 IU, and include 4,000 and 10,000 IU. So you’re sure to find the right dosage for your level of vitamin D deficiency.
