DESCRIPTION: Vitamin D3 is formed in the skin when exposed to sunlight. However, if there is no sunshine, if we do not spend a sufficient time outdoors, or if sunscreen creams are used (which can reduce vitamin D3 production by up to 90 per cent), low levels of vitamin D can already affect immunity in early autumn. During the rest of the year, the production of vitamin D3 in the skin practically does not take place. An insufficient supply of vitamin D from the sun is common.

The ability of the skin to produce the vitamin also decreases with age, which can lead to a reduction in the absorption of calcium, which is important for bones and muscle function (vitamin D is involved in the absorption of calcium). Much more sunshine is needed for the production of vitamin D3 in the skin by people with darker skin.

Low-quality and highly processed foods may not provide adequate vitamin D. And even with good nutrition, foods can usually only provide about 30 per cent of the daily requirement of this vitamin.

Because of the above, vitamin D3 supplementation is very important in our climate for everyone, from children to adults.

  • Supports¬†calcium & phosphorus absorption
  • Supports¬†normal level of calcium in the blood

MCT oil has many health benefits, for example, it doesn't adversely affect the blood lipid profile and doesn't increase the risk of cardiovascular disease. It has a much higher resistance to rancidity; the vitamins remain fresh long after the bottle is first opened (6 months). MCT oil has no taste, which is important when giving vitamins to young children.

DIRECTIONS: Place 1-2 drops under the tongue or administer on a teaspoon (for persons aged 11+ and pregnant/lactating women). Drop in the mouth and spread with the tongue. There is an increased need for vitamin D3 in obese people and those with chronic inflammatory processes. Do not exceed the recommended daily dose. 

For children under 11 years of age, this Vitamin D3 should not be taken together with any other products containing vitamin D.

In children under 1 year of age, use under medical supervision.

In the absence of endogenous synthesis, only 5 mcg (200 IU) should be taken (by children, adults, pregnant and lactating women).
