Discover the ingredients of the DUOLIFE D3 in Nigella Oil food supplement 

Vitamin D3 (cholecalciferol) also known as the “sunshine vitamin”. It is a compound belonging to fat-soluble vitamins. Unlike other vitamins, it can be synthetised by the body, albeit in limited amounts. Hence, this process depends on the time of exposure to solar radiation and occurs mainly in the skin, so vitamin D3 level in the body may depend on the lifestyle and the geographical residence, air pollution, season of the year, time of the day or skin complexion. Regular exposure of the body to the sunshine is necessary to ensure the proper level of vitamin D3 in the body. When the access to solar radiation is limited, it is recommended to supplement the vitamin level in the diet.

Vitamin D helps maintain correct calcium level in the blood.

Vitamin D contributes to normal absorption/use of calcium and phosphorus.

The food supplement also contains oil from seeds of nigella, which synergistically supports the action of the active ingredient – vitamin D3. The presence of the Nigella oil is a particularly important distinguishing feature, as the oil itself comprises an important ingredient with properties that support body functioning. It is one of the most valuable vegetable oils. 

Nigella oil is obtained from the seeds of nigella (Nigella sativa) seeds, which is native mainly to Eastern Europe and the western part of Asia. The properties of the Nigella oil have been known since the ancient Egypt, where it’s been called the “Pharaoh's gold”. The composition of the Nigella oil includes mainly essential unsaturated fatty acids (EFA). Among them, we can distinguish around 60% content of linoleic acid (omega-6) and about 25% of oleic acid (omega-9) and about 1% of alpha-linolenic acid (omega-3). Moreover, we can distinguish vitamin E, biotin, beta-carotene, mineral salts: iron, calcium, potassium, phosphorus, copper, antioxidants, sterols, and active compounds, namely thymoquinone, thymohydroquinone, p-Cymene, carvacrol, thymol.
