Supplement Description

Our Vitamin D3 4000iu is the optimum level recommended by nutritionists to quickly correct deficiency. Vitamin D supplementation can play an important role in correcting Vitamin D deficiency to ensure the maintenance of adequate levels in the body.

Vitamin D plays a number of crucial roles in the body including providing support for immune health, muscle health and strong bones and teeth. Vitamin D can be obtained through food sources such as eggs, fortified cereals and oily fish, but is predominantly synthesised in the skin through exposure to sunlight - hence why it is often as the 'sunshine vitamin'.

Most healthy adults should theoretically be able to get enough Vitamin D from being outside in the sun, however Vitamin D deficiency is very common throughout the UK. This is as a result of a low level of exposure to sunlight, making Vitamin D synthesis almost impossible during the winter.

High strength, natural form tablet

Our 4000iu high strength Vitamin D supplement provides 100µg (2000% Nutrient Reference Value) in an 8mm round, odourless tablet with no coating. We use a high quality natural form of Vitamin D, Cholecalciferol (Vitamin D3) in this supplement - the form of Vitamin D most readily absorbed by the body. Our manufacturing process gives us a highly concentrated form of Vitamin D3 which offers 99% purity and unbeatable quality.

Recommended as a food supplement by the FSA

The Food Standards Agency recommends that if you are pregnant or breastfeeding you should take a 400iu/ 10µg supplement of Vitamin D each day.

People who may be at risk from Vitamin D deficiency include people who:
  • are of Asian origin
  • rarely get outdoors
  • eat no meat or oily fish

Vitamin D and rickets in children

Vitamin D is crucial for the maintenance of health and strong bones, a deficiency in Vitamin D can cause rickets in young children which is a weakening and softening of bones which can lead to bone deformities. After World War II instances of rickets in the UK was in very small numbers due to the British government introducing cod liver oil as a supplement - this is a great food source of Vitamin D. However between 2003 and 2013 the NHS reported a 430% increase in cases of rickets and it is becoming an increasing issue.

On principal I will shop elsewhere thanks.

Feedback Response: Thanks for the positive comment about our supplements. As clearly stated in all of our offers, any discount applies to the value of your goods, excluding delivery charges. We do this because we do offer a variety of delivery options, some of which are chargeable (because they cost us a lot to supply these services) and some free (because they cost us less). Some customers are not in such a hurry for their goods, so the free-delivery option suits, but for those customers that require their goods more urgently, we do offer some paid-for delivery options. Our delivery options (and any charges) are clearly described on our Delivery Information page, then laid out very clearly on the Shopping Basket page when you review your order and again through the checkout process (where they can be adjusted if required). Just Vitamins offers Free Delivery on all UK orders - however small the order - which makes it fairly unique amongst our competitors. Thank you for shopping with us.

Product: Only just started taking the d3 supplements so havent really noticed a massive difference in the way im feeling. As i am very deficient it will take a while.
The goods arrived as expected but I have not noticed any difference yet. I assume you need time to notice any change. The tablets are easy to take and there is no nasty taste.
Service Rating: Quick service. Well packaged. Thanks.
Product: Seem to have improved the brain fog I had been experiencing. Generally feel sharper.

Product: It’s what it deserves ....
Service Rating: The vitamins I ordered arrived very quickly so I would certainly use this company again.
Product: I cannot rate the supplement just yet as I was diagnosed with very low vitamin D. Will have more blood tests in June which will show whether these vitamins have worked or not.
Service Rating: I did not find the service good. I meant to order packets of 60 and I pressed the wrong Qty ordering 30 per. I rang next morning Saturday and was told I could not alter the order but to ring another No. on the Monday. On ringing the No. Monday morning I was told it was not possible to ammend order, not happy! M J Haisman
Product: It is a supplement that was advised.
Feedback Response: I've taken a look at your order. I think you intended to order the 120 packs, but actually ordered 2 x 60 (Turmeric and Vit D 4000iu). I've refunded £6.97, which is the difference between the 2 pack sizes.
I apologise for your experience on the phone. It isn't possible to change an order, but we can easily cancel it and replace the order with the correct pack sizes. We'll review our staff training with those involved.
Service Rating: I have used just vitamins a few times for supplements always found the website easy to use as I am not computer literate. Delivery is always quick & problem free.
Product: I have only been taking them for a short while so not sure yet if they will give me the result I am looking for. I was put on Vitamin D3 by my doctor due to low levels after a blood test my hair was falling out & nails in bad condition but would only perscribe them for six months so I thought I would try taking a low dose just to keep my Vit D levels up.
Service Rating: Quick service. Amazing prices. There was a discount code available also. I got a years supply of vitamins for ubder £25
Product: Its for my wife it gives her alot more energy
