Vitamin D3 20,000 IU is a high-dose dietary supplement with natural vitamin D3 from lanolin, intended as a depot preparation for people with a very high vitamin D requirement or for short-term use in consultation with a doctor.
It is suitable for vegetarians, but not for vegans due to its lanolin origin.
The recommended intake of Vitamin D3 20,000 IU is 1 capsule every 20 days, taken with a glass of water and with a meal.
Anyone considering a higher dosage should discuss this beforehand with a doctor or therapist who has experience with vitamin D therapy.
The high single dose of Vitamin D3 20,000 IU is designed as a depot dose: the body stores vitamin D and breaks it down slowly, so one capsule every 20 days is sufficient.
It is important to adhere to the recommended intake interval and, if you plan to take it long-term with a higher frequency, to have your 25(OH) vitamin D3 level checked regularly (every 3 months) by a doctor.
The most reliable way to determine actual need is by means of a blood test to determine the 25(OH) vitamin D3 level.
Only when this value is known can an assessment be made as to whether a dosage as high as that of Vitamin D3 20,000 IU is appropriate or whether a lower-dose preparation is better suited.
Regular intake of a high-dose vitamin D supplement such as Vitamin D3 20,000 IU increases calcium absorption in the intestine, which causes the body to produce more Gla proteins for calcium transport.
These proteins are only activated by vitamin K2 – many users therefore combine Vitamin D3 20,000 IU with a K2 preparation.
You can find details on this in our guide to combining vitamin D and K2.
If too high a dose of vitamin D is taken over a prolonged period of time, this can lead to hypercalcaemia (elevated calcium levels in the blood), which can manifest itself, for example, through cardiac arrhythmia, nausea, vomiting, severe thirst or loss of appetite.
If an overdose is suspected, the intake of Vitamin D3 20,000 IU should be stopped immediately and the 25(OH) vitamin D3 level in the blood should be checked.
Side effects usually only occur when the 25(OH) vitamin D3 level exceeds 150 ng/ml.
The target range should not exceed 80 ng/ml when taking Vitamin D3 20,000 IU, which is why regular blood tests are recommended if it is taken more frequently.
Vitamin D3 20,000 IU is intended for very high, short-term or depot requirements and is only taken every 20 days, while lower-dose preparations are usually taken daily.
The appropriate dosage depends on the individual 25(OH) vitamin D3 blood level – you can find out more about this in the guide to the correct vitamin D dosage.
Due to the high single dose of Vitamin D3 20,000 IU, taking it during pregnancy or breastfeeding should be discussed in advance with a doctor who can assess the individual vitamin D requirement during this time.
