High dose Vitamin D 5000 IU capsules

"IU" stands for International Unit, a globally standardised unit of measurement for the dosage of vitamins. 

5000 IU of vitamin D3 corresponds to 125 µg of cholecalciferol – this is exactly the amount contained in one capsule of this product.

This depends on individual needs, body weight and current blood levels. 

Since 5000 IU daily is above the EFSA upper limit of 4000 IU (100 µg), we recommend consulting a doctor and regularly checking the 25(OH)D value if this amount is taken on a long-term basis, so that the level remains within the optimal range.

VitaminExpress recommends taking an additional 200 µg of vitamin K2 daily when taking high doses of vitamin D3, for example via a separate preparation such as Vitamin K2 200 mcg. Vitamin K2 supports the transport of calcium in the body.

A daily intake of 5000 IU (125 µg) is above the recommended intake for this product of 1 capsule every 5 days and also above the safe upper limit for adults of 4000 IU (100 µg) per day set by the EFSA. 

This does not automatically mean there is a risk, but anyone who wants to take 5000 IU daily on an ongoing basis should discuss this with a doctor and have their blood 25(OH)D level checked every 2–3 months initially.

The recommended intake for this product is 1 capsule every 5 days. This corresponds mathematically to around 1000 IU per day. The frequency can be adjusted individually to the season, sun exposure and the individual's blood level.

For most healthy adults, a daily intake of 5000 IU is above the recommended intake for this product and above the EFSA upper limit of 4000 IU per day. 

In this case, it is advisable to have a doctor check your blood levels to definitely rule out excessive or insufficient intake.

The recommended intake is 1 capsule every 5 days. This equates to about 1000 IU per day. The actual amount required depends on the individual's vitamin D level, sun exposure and the season, so the intake can be adjusted to personal needs.

Vitamin D3 is fat-soluble and is stored in the body's adipose tissue. This means that it does not have to be taken daily in order to maintain a stable blood level. 1 capsule every 5 days (5000 IU) corresponds mathematically to a daily intake of about 1000 IU and is a practical alternative to taking low-dose preparations daily.

No, that is not absolutely necessary. Even without additional fat intake, a normal meal usually contains enough fat, and there is anyway a small amount of fat present in the intestine, which is sufficient for the absorption of vitamin D3. If you want, you can still take the capsule after a meal.

No. Since the vitamin D3 is derived from lanolin, the product is vegetarian but not vegan.

Yes, it is even recommended. With a regular, higher-dose intake of vitamin D, the need for vitamin K2 increases, as it is involved in the distribution of calcium in the body. VitaminExpress recommends an additional 200 µg of vitamin K2 daily when taking high doses of vitamin D3, e.g., via a separate vitamin K2 supplement.

The European Food Safety Authority (EFSA) confirms that vitamin D contributes to the maintenance of normal bones and teeth, normal muscle function, normal calcium levels in the blood, normal absorption and utilisation of calcium and phosphorus, normal functioning of the immune system and normal cell division. 

These statements are approved health claims and not promises of cure.

If taken according to the recommended intake (1 capsule every 5 days), an overdose is unlikely. 

If you want to take more than 5000 IU (1 capsule) per day on a regular basis, you should initially have your blood 25(OH)D level checked every 2–3 months to ensure that the level is within the optimal range. 

If you have any existing medical conditions, are taking medication, are pregnant or are breastfeeding, you should consult a doctor or pharmacist before taking the product.  

Capsules contain the powder loose and do not have to be processed under high pressure with compression aids. They usually dissolve quickly in the stomach. Tablets, on the other hand, often require binding agents or compression aids. VitaminExpress capsules are made of 100% plant-based material and contain no colouring agents or tableting aids.

According to the manufacturer, the product is suitable for diabetics because it is sugar-free and contains no sugar substitutes. In the case of existing pre-existing conditions, however, it is advisable to consult your doctor.

Since vitamin D3 is stored in the body in a fat-soluble form, forgetting to take it on a single day usually has no noticeable effect. The next capsule can simply be taken again according to the usual schedule, without making up the dose.
