Vitamin D: benefits, deficiencies, foods, doses and intake

What is vitamin D used for?

Vitamin D is essential for calcium absorption and proper immune system function. It helps:

  • Strengthen bones

  • Prevent osteoporosis

  • Regulate mood

  • Improve immune defenses

  • Support muscle health

What are the symptoms of vitamin D deficiency?

Vitamin D deficiency is an increasingly common condition and can manifest itself with:

  • chronic fatigue

  • muscle pain

  • bone fragility

  • increased susceptibility to infections

  • low mood and depression

  • sleep disorders

What happens if you have a vitamin D deficiency?

A chronic deficiency can lead to osteoporosis , rickets , reduced immune response , and hormonal imbalances . Vitamin D is essential for calcium absorption and bone health.

What to eat when you have a vitamin D deficiency

Among the best foods rich in vitamin D we find:

  • cod liver oil

  • salmon, mackerel, tuna

  • whole eggs

  • mushrooms exposed to the sun

  • fortified milk and dairy products

Interesting fact: Few foods naturally contain vitamin D, which is why supplementation is often necessary.

In which fruits and vegetables is vitamin D found?

Vitamin D is not naturally present in significant quantities in fruits or vegetables. However, mushrooms (especially shiitake and maitake) may contain small amounts when exposed to UV light.

What is the best vitamin D and how much should you take?

The best form is vitamin D3 (cholecalciferol) , because it is more bioavailable and similar to that produced naturally by the body through sunlight.
Recommended dose: 1000-5000 IU/day , unless otherwise prescribed by your doctor.

How long does it take for vitamin D levels to rise?

It depends on the initial deficiency, the supplemented dose and the method of administration (oral or transdermal).
Typically, levels normalize within 8-12 weeks with good supplementation.

Side effects of excess vitamin D

Beware of hypervitaminosis D , which can cause:

  • nausea, vomiting

  • hypercalcemia (too much calcium in the blood)

  • kidney damage

  • calcifications of the vessels

Difference between vitamin D and D3

  • Vitamin D is a generic term

  • Vitamin D3 (cholecalciferol) is the active and most effective form

  • The D2 is less stable and less used

What are the normal values ​​for vitamin D?

  • Insufficiency: < 20 ng/mL

  • Normal: 30-60 ng/mL

  • High: > 100 ng/mL
    Levels above 150 ng/mL may be toxic.

Vitamin K2: Benefits, Differences, and Synergy with Vitamin D3

What is vitamin K used for?

Vitamin K2 helps to:

  • fix calcium in bones and teeth

  • prevent calcium from being deposited in soft tissues (kidneys, arteries)

  • prevent osteoporosis and vascular calcifications

What are the benefits of vitamin K2?

  • Activates osteocalcin (a protein essential for bone mineralization)

  • Activates matrix GLA protein (which prevents calcium accumulation in soft tissues)

  • Helps prevent atherosclerosis

Vitamin D and K together or separately

They must absolutely be taken together .
D3 increases calcium absorption, but without K2, calcium can be deposited in the wrong places , increasing the risk of calcification.

How much vitamin K2 for vitamin D

The recommended ratio is:
100-200 mcg of K2 (MK-7 form) for every 1000-2000 IU of vitamin D3 .

Difference between vitamin K and K2

  • K1 (phylloquinone): present in green leafy vegetables, acts on coagulation

  • K2 (menaquinone): acts on bones and blood vessels, more bioavailable and stable

Which foods do not contain vitamin K?

Foods lacking vitamin K :

  • Fruit (except kiwi, blueberries)

  • Skimmed milk

  • Pasta, rice

  • Lean meats

  • Refined oils
