Question 1

How can I tell if my vitamin D levels have improved after taking Vitamin D3 with K2?

Accepted Answer

To see the effect Vitamin D3 with K2 has on your vitamin D levels, you can measure your vitamin D levels with a Nutritional Health Blood Test.

Your results will be reviewed by a clinician who will give you a simple breakdown as well as advice on how to manage your vitamin D levels in the long term.

Question 2

Who should take vitamin D supplements?

Accepted Answer

Public Health England (PHE) recommends that everyone consider taking a daily 400IU (10mg) vitamin D supplement in autumn and winter, as there’s less sunlight during these months. According to PHE, products providing up to 25 micrograms (1000 IU) are suitable for everyone.

They also recommend that certain people (who are at greater risk of having low vitamin D) consider taking a vitamin D supplement all year round. These people include:

Those who spend a lot of time indoors.
Older people.
Those with darker skin.
Those who cover most of their skin when outside.

One tablet of Vitamin D3 with K2 contains enough vitamin D to meet Public Health England’s daily recommended amount.

Question 3

Is it possible to take too much vitamin D?

Accepted Answer

However, if you do take too much vitamin D, signs of toxicity include:

Nausea
Vomiting
Low appetite
Constipation
Weakness
Weight loss
Polyuria
Excessive thirst

Too much vitamin D can also raise blood calcium levels, which may cause confusion, disorientation, and problems with heart rhythm.

If you experience symptoms of vitamin D toxicity, stop taking vitamin D supplements and consult your doctor.

Question 4

What time of day can I take Vitamin D3 with K2?

Accepted Answer

You can take the supplement at any time of the day. However, we recommend that you take it at the same time each day so you get into a routine of taking it.

If you forget to take it one day, don’t double the dose to make up for the one you missed. Instead, take it as normal the following day.

Question 5

What's the difference between vitamin D and D3?

Accepted Answer

In dietary supplements, vitamin D comes in two forms: vitamin D2 and vitamin D3.

Vitamin D2 is typically found in plants, whereas vitamin D3 is usually found in animals and humans when sunlight makes contact with their skin.

Both vitamin D2 and vitamin D3 are effective in raising the levels of measurable vitamin D (known as 25-hydroxyvitamin D) in the blood. However, our supplement contains vitamin D3 because research has shown that vitamin D3 is more effective at raising measurable vitamin D than vitamin D2.

Question 6

Is there any safety information I should be aware of before using a vitamin D supplement?

Accepted Answer

Who Vitamin D is suitable for

Vitamin D is suitable for people aged 18 and over.

As with any dietary supplement, consult your doctor before using this product, especially if you take medication regularly, are about to have surgery, or are under regular medical supervision.

If you take too much vitamin D

Taking too much vitamin D may lead to vitamin D toxicity. Vitamin D toxicity is rare and usually only happens when you consume too much vitamin D using vitamin D supplements. The daily upper limit for vitamin D supplementation is 4000IU.

If you take too much vitamin D, signs of toxicity include:

Nausea
Vomiting
Low appetite
Constipation
Weakness
Weight loss

Too much vitamin D can also elevate blood calcium levels, which can cause confusion, disorientation, and problems with heart rhythm.

Allergies and intolerances

We constantly review the safety information we provide to make sure our products meet our patients’ needs. While we strive to make sure our information is as accurate as possible, those with allergies and intolerances should always check product labelling, warnings, and directions provided with the product before use or consumption.

Taking vitamin D with other medicines

Like most dietary supplements, vitamin D may interact or interfere with other medicines or supplements you might be taking. Some examples include:

Prednisone and other corticosteroid medicines to reduce inflammation.
Orlistat (weight-loss drug) and cholestyramine (cholesterol-lowering drug).
Phenobarbital and Phenytoin (drugs used to control epileptic seizures).

Talk to your doctor about taking a dietary supplement to ensure it is safe for you to take and doesn’t interact with any medication (prescription or otherwise) you are taking.
