An oral spray method of vitamin D supplementation can provide the same rate of improvement in vitamin D levels as compared to pills, according to newly published research.
Vitamin D is a crucial factor for our health. Recognizing this, health experts are increasingly recommending supplementation with this essential micronutrient. Whilst, in recent years, the recommended daily allowance (RDA) of vitamin D has been raised in some countries, to achieve optimal levels all the year round an extra supply is especially needed during the winter months.
A micronutrient that has numerous important functions in the body, vitamin D is produced naturally when skin is exposed to sunlight. But in order for this process to happen, the body has to receive sufficient sunlight in the first place. Not only is this difficult to achieve during the winter months, during summer months government health authorities increasingly advise using sunscreen as a protective measure against ultraviolet (UV) radiation, a known risk factor for skin cancer. Sunscreen typically nullifies the body’s ability to produce vitamin D. As synthesis in the skin is essentially the body’s main source of vitamin D, daily supplementation makes a lot of sense.
When choosing a vitamin D oral spray product, always make sure it uses the cholecalciferol (vitamin D3) form. The most bioavailable type of vitamin D, cholecalciferol is the same form that is produced naturally in the body when skin is exposed to sunlight.
