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 take a daily supplement of at least 10mcg (400iu) of vitamin D. However, this recommendation is designed to prevent deficiency rather than achieve optimal levels.

The Endocrine Society suggests a higher daily intake of 1000iu to provide therapeutic benefits and maintain optimal health. While the official upper safe limit in the UK is 4000iu per day, higher doses (up to 10,000iu daily) can be safely used for short periods to correct deficiencies or insufficiencies, under professional supervision.

We recommend regular testing of your vitamin D levels if you're taking higher doses, to ensure you're maintaining appropriate and safe levels.

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.

Typically, it requires a few weeks of taking regular vitamin D supplements to see an increase in vitamin D levels within the body. Vitamin D3 is known for supporting bone health.

Research suggests that the effectiveness of vitamin D3 supplements is not significantly influenced by the time of day, however, the key is consistency. Whether you choose to take it in the morning or at night, maintaining a regular schedule is crucial to ensure a steady supply of vitamin D3 into the body, helping to achieve and maintain optimal levels over time.

Vitamin D is a broad term which refers to both the D2 and D3 forms of vitamin D. Vitamin D2 is derived from plants, whereas D3 is from animal sources and the same form as produced by the body in response to sunlight. Studies indicate that D3 is more effective in raising blood levels of vitamin D, making it an optimal choice for supplementation.

Vitamin D3 is naturally present in certain foods including fatty fish like salmon and mackerel, egg yolks, and liver, or fortified foods such as orange juice or milk. However, obtaining sufficient levels through diet alone can be challenging therefore supplementation may be required.

Yes, this can safely be taken alongside our Multi Essentials range. However, if you plan to use both supplements together long-term, we recommend regular testing to ensure optimal nutrient levels and avoid exceeding recommended amounts.

Our vitamin D is sourced from lanolin, a natural substance extracted from sheep's wool. This provides vitamin D in the highly absorbable D3 (cholecalciferol) form, identical to what your body produces when exposed to sunlight.

We recommend regular testing when supplementing vitamin D long-term, as it’s a fat-soluble vitamin that is stored in your body. Regular testing ensures your levels remain optimal and helps avoid potential toxicity from excessive intake.
