A vitamin should normally be obtained by diet alone, but as vitamin D is often required from our food intake as well, it is included in this category. Dietary sources of D3 include oily fish and eggs. Vitamin D2 (ergocalciferol) is found in alfalfa and mushrooms, but D2 requires conversion into D3 in the body. However, Vitamin D2 seems to be as efficient in supporting bone health as Vitamin D3.How does it work in the body?Vitamin D3 (cholecalciferol) is converted into calcidiol in the liver and from there into calcitriol by the kidneys. Kidney calcitriol is an active hormone that regulates phosphate and calcium in the body. This hormone is key in supporting bone health. Calcitriol made outside of the kidneys can regulate cellular life cycles, including differentiation into specific cell types. This includes the variety of white cells involved in the immune system. Not only does vitamin D support our immunity, it also plays a role in a healthy nervous system, as well as healthy muscles and teeth.Who may be at risk of low vitamin D levels?Although people with pale skin may need to supplement with additional vitamin D, as it is thought that either it is because they burn so easily or because they also may not be able to process vitamin D as efficiently. Other groups who are at risk are those with dark skin, the elderly, young children, as well as pregnant and breastfeeding women. Even some of the health-related charities are now calling for an increase in our vitamin D intake.So what constitutes a deficiency of vitamin D?Blood levels of less than 25nmol/L are considered to be a true deficiency, but scientists are now considering 60nmol/L to be suboptimal. Because vitamin D is fat-soluble, there have been concerns that we may easily build up too much in the body. However, Dame Sally Davis has stated that a ‘significant proportion of people in the UK probably have inadequate levels of vitamin D in their blood’ and many health advisers, such as GPs, nurses and midwives are now being urged to advise patients to increase their intake of this vitamin.
Children were traditionally given supplements to increase vitamin D levels, but this practice ceased in the 1950s. We have come full circle and it is not only children that may require supplementation. As a company, we feel it is our responsibility to ensure that we provide the best products in keeping with current guidelines. So, in response to this, Nutrigold has introduced a new version of the vitamin D3 supplement, which delivers 1000iu of highly bioavailable vitamin D3 in the same sized capsule.
How much do we need daily?Currently, the RDA (Minimum recommended allowance) for Vitamin D is 5µg (= 200iu) with a suggested USL (Upper safety level for long term use) of 1000iu (EVM SUL). However, this is now under review by the Department of Health and the Scientific Advisory Committee on Nutrition, as the minimum recommended daily allowance is not considered to be sufficient to meet our dietary needs.The Upper Safety Levels (USL) set by the Expert Group on Vitamins and Minerals (EVM) are not mandatory; they are issued as a guideline for long term usage. However, the levels chosen are often selected from data of several studies. As an example, researchers in one study used the equivalent of 4000iu for individuals over a period of 5 months (Vieth et al, 2001), where there were no adverse effects on calcium utilisation. This study illustrates that the practitioner is not necessarily bound by the USL in the therapeutic setting, so long as it is within the confines of good practice.(Vieth R, Chan P-C, MacFarlane G D (2001). Efficacy and Safety of Vitamin D3 intake exceeding the lowest observed adverse effect level. American Journal of Clinical Nutrition; 73: 288-94.)
