What is IU?

SunVit-D3 contains different strengths of vitamin D3 and the ‘IU’ stands for International Units. International Units are used to measure the biological activity of vitamins and are based on the same measure as micrograms but are not equivalent.


What is µg?

SunVit-D3 contains different strengths of vitamin D3 and the ‘µg’ or ‘mcg’ stands for micrograms. Micrograms are used to measure the biological activity of vitamins and are based on the same measure as International Units (IU) but are not equivalent. 1 IU is the biological equivalent of 0.025 µg cholecalciferol.


What is the current Nutrient Reference Value (NRV) of vitamin D3?

The current Nutrient Reference Value of vitamin D3 is 200 IU (5µg).


Why are there so many strengths of SunVit-D3?

We have launched the high strengths of SunVit-D3 in response to requests from Consultants, GPs and Healthcare professionals in the UK for a high-quality vitamin D3 product manufactured under GMP in the UK. All our production batches are tested and come with a Certification of Analysis.


How many supplements are in a pack?

All of our packs come in 28 film coated tablets or capsules, except the 50,000IU high strength SunVit-D3 supplements which come in packs of 15 film-coated tablets and 10 capsules respectively. Please see the Vitamin D3 product page for more information.
How do I dispose of our products?

All of our cartons and leaflets are recyclable so please place in recycling bin.


Vitamin D

Who needs vitamin D supplements?

The Department of Health recommends:
– All pregnant and breastfeeding women should take a daily supplement containing 10 µg of vitamin D. This is to ensure the mother’s requirement for vitamin D are met and to build adequate fetal stores for early infancy.
– All babies and young children aged 6 months to 5 years should take a daily supplement containing vitamin D in the form of vitamin drops, to help them to meet the requirement set for this age group (7-8.5 µg of vitamin D per day). However, those babies who are fed infant formula milk will not need vitamin drops until they are receiving less than 500ml (about a pint) of infant formula a day, as these products are fortified with vitamin D. Breastfed infants may need to receive drops containing vitamin D from one month of age if their mother has not taken vitamin D supplements throughout pregnancy.
– People aged 65 years and over and people who are not exposed to much sun should take a daily supplement containing 10 µg of vitamin D.


Who is at risk of not getting enough vitamin D?

The current advice is that most people should be able to get all the vitamin D they need by getting enough sun and eating a healthy balanced diet. However, the Department of Health recommends that supplementation may be helpful for the following groups of people:
– All pregnant and breastfeeding women – vitamin D stores get used up during pregnancy, so women who have several pregnancies close together are at higher risk
– Infants and young children aged under five years old – babies of mothers who are deficient, particularly breastfed babies from 1 to 6 months
– All people aged 65 or over – housebound people in nursing and residential homes are particularly at risk
– People who have low or no exposure to the sun – overuse of sunscreen, particularly high factor SPFs.  People who cover their skin for cultural reasons.  Sports people who spend all day training indoors.
– People who have darker skin – people of South Asian, African and Afro-Caribbean origin as their bodies are not able to make as much natural vitamin D.


Should anyone NOT take vitamin D3 supplements?

SunVit-D3 may be given to children under 11 years providing you seek advice from your doctor or pharmacist. Pregnant or nursing women should consult their doctor before use.


What dosage should I take?

The recommended daily maintenance dosage is 400IU daily (or 10µg) as outlined in the NICE (National Institute for Health and Care Excellence) guidance. The guidance was developed to ensure that the UK population has a satisfactory level of Vitamin D throughout the year, in order to protect musculoskeletal bone health. The guidelines also recognise that Halal supplements must be made readily available to at-risk patients. The SACN (Scientific Advisory Committee on Nutrition) has recently issued consumption guidelines on Vitamin D within their health report published on 21 July 2016 to protect bone and muscle health.



What is the Daily Recommended Intake for Calcium?

Adults (19-64 years) need 700mg of calcium a day.


What happens if I take too much calcium?

Taking high doses of calcium (more than 1,500mg a day) could lead to stomach pain and diarrhoea.


What does the Department of Health advise?

You should be able to get all the calcium you need by eating a varied and balanced diet. If you take calcium supplements, don’t take too much as this could be harmful. Taking 1,500mg or less a day is unlikely to cause any harm.


Can tablets be crushed and taken?

Unfortunately, our tablets are Film-coated and not recommended for crushing. If you are experiencing difficulty in swallowing the tablets then we would advise you to purchase our liquid maintenance products in the form of the Oral Solution 2,000 IU, 3,000 IU or the Oral Drops 2,000 IU.


Are there any side effects?

Vitamin D is the most likely of all vitamins to cause toxicity. Whilst toxicity is unlikely to arise after an acute overdose, excessive chronic vitamin D intake may lead to hypercalcaemia and hypercalciuria and their associated effects.


Can I overdose on SunVit-D3?

Excessive sun exposure does not result in vitamin D toxicity due to auto-regulation mechanisms that limit the amount produced in the skin. Intakes of vitamin D in food that are high enough to cause toxicity are very unlikely. Toxicity is much more likely to occur from high intakes of dietary supplements containing vitamin D. Vitamin D promotes the absorption of calcium and the resorption of bone resulting in the deposition of calcium in soft tissues, diffuse demineralization of bones and irreversible renal and cardiovascular toxicity. Moderate levels of vitamin D intake may enhance renal stone formation in predisposed individuals.


Are there any foods I shouldn't eat or supplements I shouldn't take while taking SunVit-D3?

You can continue to eat vitamin D3 rich foods such as oily fish and take other vitamin and mineral supplements in conjunction with SunVit-D3.


Does this product contain peanut oil or other nut products?

Although SunVit-D3 does NOT contain peanut oil or any nut products, it is manufactured on a site that also manufacturers products containing nuts.


I am lactose intolerant, can I take SunVit-D3?

We have recently launched our 800IU and 2,000IU tablets as dairy free and are launching the remainder of the tablet range as dairy free over the next 12 months. We would advise customers with lactose intolerance to take our capsules or liquid preparations which do not contain Lactose (Milk) or the 800IU and 2,000IU tablets.
In the pharmaceutical industry, lactose is used to help form tablets because it has excellent compressibility properties. Most medications do not contain enough lactose to cause lactose intolerance. But some patients with severe lactose intolerance may experience symptoms. Patients who are specifically “allergic” to milk (not just lactose intolerant) should not use tablets containing lactose.


Is SunVit-D3 suitable for vegetarians?

The vitamin D3 (cholecalciferol) used in SunVit-D3 is derived from lanolin which is found in sheep’s wool. Many vegetarians consider this to be an acceptable source of vitamin D3 (cholecalciferol). SunVit-D3 is free from gelatine, yeast, wheat, soy and gluten. SunVit-D3 is approved by The Vegetarian Society.
