Vitamin D Boost Safety Information Page

Taking control of your health starts here

Thank you for choosing Numan. We salute your decision to take control of your health and wellbeing, and we will support you along every step of the way.

This Safety Information Page is intended to help you use your Vitamin D Boost safely and effectively. Please read it carefully, along with the information leaflet included with your Vitamin D Boost.

Who Vitamin D Boost is suitable for

Vitamin D Boost is suitable for adults and children aged 13 and above.

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

Allergies and intolerances

We constantly review the information on our Safety Information Pages and 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.

How to use Vitamin D Boost

When you use Vitamin D Boost for the first time, you may need to press the pump a few times to get the liquid flowing. Once you have done this:

  1. Shake the bottle before use.
  2. Spray Vitamin D Boost once onto the inside of your cheek and keep it there for a few seconds. One spray delivers 1000IU vitamin D.
  3. Replace cap after use.

You can take vitamin D Boost at any time of the day, with or without food.

If you take too much vitamin D

Taking too much vitamin D may lead to vitamin D toxicity. Vitamin D toxicity is very rare and only occurs with excessive vitamin D supplementation. The daily upper limit for vitamin D supplementation is 4,000IU.

One spray of Vitamin D Boost contains 1,000IU vitamin D, which means it’s highly unlikely to cause vitamin D toxicity if taken correctly.

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

  • Nausea
  • Vomiting
  • Poor appetite
  • Constipation
  • Weakness
  • Weight loss

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

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.

Storage and additional instructions for use

Keep out of reach of children. Store in a cool, dry place. Do not use if safety seal is broken or missing. Supplements should not replace a healthy diet and lifestyle. Do not spray in eyes. If it gets in the eyes, rinse with warm.
