Description

What is Vitamin D?

Vitamin D is usually created by the body from exposure to direct sunlight. During the winter and autumn months when there is less sunshine, many people need dietary supplements to maintain a healthy level of vitamin D. 

How does it work?

Vitamin D is used to help regulate the amount of calcium and phosphate in the body. The body needs these nutrients to keep bones, teeth and muscles healthy.

Is Vitamin D suitable for me?

If you are vitamin D deficient you may need to take a supplement. It is recommended for people who are not outdoors very often, those who are in an institute such as a care home or who wear a lot of clothes when outdoors should take a vitamin D supplement. This supplement may also be suitable for you if you have dark skin (e.g. if you have an African-Caribbean or south Asian background) and you cannot make enough vitamin D from sunlight.

Side Effects

Do not take more than 100 micrograms of vitamin D a day as it could be harmful. If you take too many vitamin D supplements over a long period of time it can cause too much calcium in the body which may weaken the bones and damage the kidneys and heart.

Additional Information

Vitamin D is an important vitamin that helps our bodies absorb calcium and phosphorus. It also helps to keep our bones healthy and strong. Vitamin D deficiency can lead to several health problems, including weakened bones, rickets, and osteoporosis.

Most people get the vitamin D they need from exposure to sunlight. However, some people may need to take vitamin D supplements, especially if they have dark skin or are not able to get enough sun exposure. Vitamin D supplements are available in many different forms, including tablets, capsules, liquids, and injections.

If you think you might be deficient in vitamin D, talk to your doctor or healthcare provider. They can recommend a blood test to check your levels and recommend the best way to get the vitamin D you need.

Vitamin D Supplements

Vitamin D is a fat-soluble vitamin that is naturally present in very few foods, added to others, and available as a dietary supplement. It is also produced endogenously when ultraviolet rays from sunlight strike the skin and trigger vitamin D synthesis. Vitamin D obtained from sun exposure, food, and supplements are biologically inert and must undergo two hydroxylations in the body for activation. The first occurs in the liver and converts vitamin D to 25-hydroxyvitamin D3  (25OHD3), also known as calcidiol. The second occurs primarily in the kidney and forms the physiologically active 1,25-dihydroxyvitamin D3  (1,25(OH)2D3), also known as calcitriol.

Both 25OHD3 and 1,25(OH)2D3 circulate in the blood bound to vitamin D-binding protein  (DBP). DBP is a transport protein that preferentially delivers vitamin D to the liver for conversion to its active metabolites. Vitamin D has a half-life of approximately 15 days and is metabolized in the liver and kidney. The biological half-life of 1,25(OH)2D3 is only about 4–6 hours due to its high level of renal clearance. Consequently, circulating 1,25(OH)2D3 levels are very tightly regulated by parathyroid hormone (PTH) and serum calcium levels. PTH increases 1,25(OH)2D3 production by stimulating the conversion of 25OHD3 to 1,25(OH)2D3 in the kidney. Serum calcium levels also influence 1,25(OH)2D3 production. Low calcium levels stimulate PTH secretion and lead to an increase in 1,25(OH)2D3 production, while high calcium levels have the opposite effect.

Vitamin D Support

1,25(OH)2D3 is the most potent form of vitamin D and is responsible for maintaining serum calcium and phosphorus levels within a tight physiological range. This homeostatic mechanism ensures that bone mineralization occurs at an optimal rate and prevents both hypocalcemia and hypercalcemia. 1,25(OH)2D3 also plays an important role in calcium absorption from the gastrointestinal tract and bone remodelling.

The Recommended Dietary Allowance (RDA) for vitamin D is 600 IU/day for adults up to age 70 and 800 IU/day for adults over 70. However, many experts believe that these levels are too low and that the RDA should be increased to 1000-2000 IU/day. Vitamin D toxicity is very rare and typically only occurs when taking extremely high doses of vitamin D supplements (i.e., >10,000 IU/day). Symptoms of vitamin D toxicity include nausea, vomiting, poor appetite, constipation, weakness, weight loss, and kidney stones.

Vitamin D deficiency is common, especially in the elderly. Deficiency can lead to several health problems, including osteoporosis, rickets, falls, and fractures. Vitamin D supplementation is an effective way to prevent or treat vitamin D deficiency. Supplementation is also recommended for people at risk for a deficiency, such as those with dark skin or limited sun exposure.

Can I take Vitamin D Tablets daily?

Yes, you can take Vitamin D Tablets daily. Speak with your doctor or healthcare provider to determine the best dosage for you. It is generally recommended that adults take between 400-800 IU of vitamin D per day.

Why should I take Vitamin D Tablets?

Vitamin D is an important nutrient that helps the body absorb calcium and phosphorus, two minerals essential for bone health. Vitamin D also plays a role in muscle function, immunity, and cell growth. A vitamin D deficiency can lead to Rickets, a condition characterised by softening and weakening of the bones. Vitamin D supplements are often recommended for people who do not get enough sun exposure, as the body produces vitamin D when exposed to sunlight. Older adults, people with dark skin, and those who are obese may also be at risk for vitamin D deficiency and may benefit from supplementation. Speak with your doctor or healthcare provider to see if vitamin D supplementation is right for you.

Is this medication suitable for me?

Please get in touch with a doctor if you are unsure what medication is suitable for you. You can also complete our online consultation form to check your eligibility for the product.

All our medication is packaged in plain confidential padded white or brown envelopes. This ensures that your orders are discreet, and the content of the orders will be for your eyes only.

When should I use Vitamin D Tablets?

Vitamin D supplements are recommended for people who do not get enough sun exposure, as the body produces vitamin D when exposed to sunlight. Older adults, people with dark skin, and those who are obese may also be at risk for vitamin D deficiency and may benefit from supplementation.

When is the best time to take Vitamin D Tablets?

There is no one definitive answer to this question as everyone's needs may vary slightly. However, it is generally recommended that you take your vitamin D supplement with a meal in order to maximise absorption. Fatty foods can help increase the absorption of vitamin D, so taking your supplement with a high-fat meal may be ideal. Additionally, it is important to take vitamin D supplements with a calcium supplement or food sources of calcium, as vitamin D is necessary for calcium absorption. Speak with your doctor or healthcare provider if you have any specific questions about when and how to take vitamin D supplements.
