The vitamin D in MARNYS® Vitamin D 4000 IU provides the following properties (EFSA):

  • Contributes to normal maintenance of bones, teeth and muscle function.
  • Vitamin D contributes to normal absorption and use of calcium and phosphorus, in addition to normal blood calcium levels.
  • Contributes to normal function of the immune system.

MARNYS® Vitamin D 4000 IU makes its ingredient (vitamin D3) recommended for people who seek to maintain their bone system, for the growth of bones in adolescents, for muscle and immune function, as well as for maintaining normal calcium absorption and use by the body.

Bone, muscle and immune function: the roles of vitamin D

Vitamin D can be obtained from dietary sources or synthesised by the body due to the exposure to UV radiation from the sun. Although it is more appropriate to refer to vitamin D as a hormone, vitamin D is similar to true vitamins as humans deprived of sun exposure are dependent on a food source. The synthesis of vitamin D in the skin by the action of sunlight is insufficient to meet the needs of northern European countries, especially during winter when there is little exposure to sunlight.1

The main physiological function of vitamin D in all vertebrates, including human beings, is to maintain blood calcium and phosphorus concentrations at a level that supports cellular processes, the neuromuscular function and bone formation. Vitamin D achieves this goal by increasing the efficiency of the small intestine to absorb calcium and phosphorus from the diet, and by mobilising calcium and phosphorus from bones.1

An adequate intake of vitamin D is needed to achieve a sufficient amount for the normal mineralisation of bones and teeth during childhood and adolescence, and for bone maintenance in adults and the elderly. Vitamin D deficiency has been shown to reduce the accumulation of minerals in the bones of children and adolescents, and to accelerate bone loss in adults and the elderly.1

From a public health perspective, the benefits of a higher vitamin D concentration in bone mineral density (BMD) is of interest to different age groups. Higher BMD protects against fractures in older adults, while in younger adults a positive association is related to the concept that higher blood vitamin D levels can contribute to peak bone mass. Accordingly, maintaining high levels of vitamin D in younger adults might further protect against fractures at older ages.2

Apart from the effects on calcium metabolism and bones, vitamin D, and especially its biologically active metabolite, act as powerful immune-regulators. The discovery that vitamin D exerts activity in monocytes, macrophages and immune organs such as the thymus suggests a specific role for vitamin D and its metabolites in the immune system. Most cells of the immune system, except B cells, have got an affinity for vitamin D.3
