Vitamin D Deficiency in Egypt: Why Take D3 with K2?
Why so many people in Egypt are low in vitamin D despite the sun, the signs of deficiency, how to take D3 with K2 properly, and who should ask a doctor first.
It may seem strange that a country with sun all year round has a vitamin D problem, but many studies in Egypt have found that a large share of people are deficient, especially women.
Why does it happen?
- Most of us spend the day indoors, at the office or in the car.
- When we do go out, most of our skin is covered.
- Few foods contain vitamin D: oily fish and egg yolks, and not much else.
Signs you might notice
- Constant tiredness with no clear reason
- Muscle or bone aches
- Getting sick often
- Low mood
These signs can have other causes, so a blood test is what confirms it. Ask for a vitamin D or 25-hydroxy vitamin D test.
Why D3 with K2?
- Vitamin D3 helps your body absorb calcium and supports immunity, muscles and hormones.
- Vitamin K2 helps direct that calcium to your bones and teeth, rather than places it should not build up.
That makes the two a sensible pair, especially if you take higher doses of vitamin D for a long time.
How to take it
- Take it with a meal that contains fat, like eggs or food cooked in oil, because vitamin D is fat-soluble.
- The time of day does not matter. Take it every day.
- If your test shows a severe deficiency, your doctor may give you a higher dose for a while.
We stock two options:
- NOW Foods Vitamin D3 & K2: a moderate dose for daily use.
- Nutricost Vitamin K2 + D3: a higher vitamin D dose, for people with a deficiency confirmed by a test.
Who should ask a doctor first?
- Anyone on a blood thinner such as warfarin: vitamin K affects how it works, so do not take K2 without asking your doctor.
- Anyone with kidney problems or high calcium levels.
- Women who are pregnant or breastfeeding.
Do not raise the dose on your own. Vitamin D is stored in the body, and very high doses over a long time can be harmful.
