Vitamin D3 High Strength 60 Tablets

Evidence shows that as many as one in five of us in the UK have low levels of vitamin D, which is essential for bone health and immunity. Vitamin D3 High Strength is designed to offer high strength vitamin D support, with 5000iu in a single, small-sized daily tablet. This higher strength supplement is suitable for those with a vitamin D deficiency, or insufficient levels, to gain optimal therapeutic benefits.

At a cost of just 16p per tablet, our high strength vitamin D3 is a cost-effective and convenient way to top up your vitamin D levels.

At Nutri Advanced, we use vitamin D3, the body’s preferred form of this nutrient for optimal absorption and efficacy.  This is the same form made in the skin in response to sunlight, meaning it is easier and faster for the body to absorb than other forms.

Vitamin D3 plays an important role in supporting a healthy, balanced immune system. Because it helps to balance the immune system, it's important for those with over-active immune systems too. It is also needed for bone health - without it, our bodies cannot absorb calcium which is critical for strong bones and is needed for muscle function. This is important in older people who may be more at risk of falling, a risk factor for fractures. It is also very important for the normal growth & development of bones in children.

Between October and March, everyone in the UK is at risk of low levels of vitamin D, as during those months we cannot generate enough vitamin D in the skin through sunlight, and it is very difficult to consume enough through food. Those aged over 65, those with limited exposure to sunshine, and people with darker skin types have a higher risk of vitamin D deficiency.

The UK government recommends that everyone over the age of 1 should be taking 10mcg (400iu) of vitamin D daily, however this is a base level, and the Endocrine Society recommend 1000iu for optimal, therapeutic benefits. Vitamin D toxicity is very rare. In the UK, the upper safe limit is 4000iu per day, however doses up to 10,000iu daily have not been shown to cause toxicity so you can be rest assured that it is not easy to ingest too much vitamin D. We recommend regular testing of your vitamin D levels when taking this product.

Symptoms of vitamin D deficiency such as muscle aches and pains, frequent colds and flus, low immune function and bone weakness may improve once vitamin D levels are elevated into the normal range. The amount of time to rectify deficiencies will depend on the level of vitamin D deficiency which is why we always recommend regular vitamin D testing. For moderate to severe deficiency this can take between 8 and 16 weeks.
