Vitamin D3 supplements, Bio-Vitamin D3 from Pharma Nord contains vitamin D3 dissolved in cold-pressed olive oil and encapsulated in small, easy-to-swallow “pearls” of soft gelatine.

Vitamin D contributes to normal functioning of the immune system, contributes to the maintenance of normal teeth and bones, supports normal muscle functioning, and plays a role in the body’s cell division and specialisation.

When UV rays hit the skin, the active form of vitamin D is formed. The body’s ability to produce vitamin D is reduced with age, however the vitamin D synthesis is inhibited by lack of sunshine or covering up with clothes. Pregnant and breast-feeding mothers, young children, elderly people and those with dark skin may also require supplemental vitamin D due to inadequate UV exposure.

Why Pharma Nord Bio-Vitamin D3:

  • Manufactured to pharmaceutical standards.
  • We offer four strengths of Vitamin D3, in oil-based capsule form for enhanced absorption.
  • Contains a form of vitamin D (cholecalciferol) naturally produced in the skin.

What is vitamin D3?

Vitamin D3 (also known as cholecalciferol) is a fat soluble vitamin.

The majority of vitamin D in the body is created during skin exposure to sunlight, but many people in Northern Europe and the USA do not get adequate exposure. Small amounts of vitamin D can also be found in egg yolk, fish oils and oily fish such as salmon, herring and mackerel. Cholecalciferol is an animal source of vitamin D3 (derived from lanolin).

Vitamin D3 (cholecalciferol) is the most easily absorbed form of vitamin D. Vitamin D3 is lipisoluble (dissolves in oil), so an oil-based preparation is best.

Pharma Nord's Vitamin D3 supplements is specially formulated in gel 'pearls'. Our preparation is dissolved in cold pressed organic olive oil to enhance absorption. It contains the cholecalciferol form of D3, which is produced naturally in the skin.

How does vitamin D3 work?

Vitamin D3 increases the absorption of calcium from food and reduces the excretion of calcium from the body. These effects ensure that calcium levels are maintained and allow adequate levels to be stored in bones and teeth. If blood calcium levels are too low, calcium may be mobilised from bones for use elsewhere in the body, resulting in bone weakening.

Vitamin D3 is also responsible for maintaining healthy muscles and nerves, and for maintaining a healthy immune system.

Studies have shown that vitamin D may stimulate the body's production of anti-viral and anti-bacterial proteins. Some experts say they would choose vitamin D before vitamin C when considering cold and flu protection.

How much should you take?

Pharma Nord recommends the following... 

800IU - 1-5 capsules per day, or as recommended by a physician.

1,000IU - 1-5 capsules per day, or as recommended by a physician.

5,000IU - 1 capsule per day, or as recommended by a physician.

Short on sunshine? Take action!

The UK government recommends vitamin D3 supplementation for several key groups of people, including all pregnant and breast-feeding mothers, all young children from 6 months to 5 years old, people over 65 years of age and those with low or no exposure to the sun.

Nutrient Reference Values
Vitamin D3 is 5mcg per day. This amount is purely to avoid deficiency and has long been viewed as inadequate, (for more information ask for our leaflet ‘Why the NRV is not enough').

Are there adverse effects from taking Bio-Vitamin D3?

People with hyperparathyroidism and sarcoidosis should consult a physician before taking vitamin D3.

Vitamin D3 taken in excess (10,000IU) may cause kidney stones and headaches.

Pregnant or lactating women and those on medication should consult a doctor before using any product.

Vitamin D in oil has better absorption

Supplements with vitamin D in oil are absorbed more easily by the body than those in powder or ethanol form, according to American researchers. The D-Pearls vitamin D supplement from Pharma Nord uses oil for this exact reason.

More and more people are taking a daily supplement of vitamin D, a nutrient that is touted for its huge impact on human health. They may be doing themselves a favour by choosing a supplement with vitamin D in oil, as this appears to increase the absorption of the vitamin.

Better absorption in oil

According to American scientists who have reviewed four clinical studies of different vitamin D formulations, supplements that use oil as a transport vehicle have better bio-availability than products that use powder or ethanol. Their research is published ahead of print in Molecular Nutrition & Food Research.

Fast reliable service easy to take little pearls with accurate dose

Ansar | 24/02/2017

I've rated 4* because after taking 800IU D3 I would get hiccups that would last a long time. I'm pretty certain that it is by no means due to the supplement's quality but rather how my body has taken to it. I've used pharma nord products for a very long time and this is the first time it's happened to me. Due to the duration and intensity of hiccups I've decided to discontinue using the D3. However my wife continues taking it without any problem.

Lynne Savage | 25/07/2016

I always take a tiny pearl each morning with breakfast and increase this to two during the winter months. Recommended.

Janice Beedham | 29/04/2016

Have been taking Pharma Nord Vitamin D3 5000 since October 2015.Due to the lack of sunlight during the winter months, I believe taking a D3 supplement is essential and the Pharma Nord version in little capsules is the best. D3 is essential for the immune system. It's not just about protection from colds and flu but more serious illness too ! Definitely recommended.

Karen | 01/03/2016

I have purchased vitamins for many years but have recently, through my daughters recommendation, discovered Multivits. I have been delighted with the quick deliveries and discounts offered and feel that already, after only 9 weeks, I am starting to feel the benefit of my purchases. My consultant recommended I take vitamin D and I feel the quality from Multivits is of exceptional quality. I would certainly recommend them to friends without hesitation.

Janet | 17/03/2014

Blood tests 'before and after' have proved to me that Pharma-Nord's Vitamin D3 pearls improve Vitamin D3 levels. My lung function has improved since using them. I have seen an improvement in a friend's psoriasis and asthma since he has been using Vit D3 800 mcg regularly.

Karen | 09/12/2013

I bought vitamin D3 pearls from this company as I couldn't find them locally in the shops (the only ones in the shops were powder tablets). I was very pleased with the ingredients used in the pearls - the presentation in blister pack very good also. Have been taking them a few days - they are easy to take and easy on my stomach. Overall I am very pleased with the quality of the project and the value for money.

Ms J Hughes | 05/12/2013

I have to comment on my experience of your wonderful products, I am 62 ex service widow with few health conditions. Arthritis means i'm stiff as board and now I have Iritus which I take steroids for from eye hospital. I bought BIO PYCNOGENOL, BIO -FISH OIL and BIO-VIT D 5000, I FEEL FANTASTIC TO WHAT I DID BEFORE I TOOK THEM. Tina Turner again ,well I can feel the difference in myself more wide awake ,not quite as stiff, more positive mood and i'm sure this is your products, also good treatment of Bristol eye hospital. I did ask pharmacist first if it would be ok to take products with steroid drops,yes they said and BINGO feeling in pink again.

T Pill | 04/09/2013

Bio-Vitamin D3 is a great product, the tiny pearls are really easy to swallow and I will now increase my daily intake as we head into the autumn/winter season. Working in an office environment it is very easy to pick up coughs and colds. Since taking Bio-Vitamin D3 I rarely seem to suffer and when I do the symptoms never seem as bad.

Elaine Scott | 04/09/2013

This product has helped to improve the strength of my nails that have always been weak and brittle. It has also helped with maintaining a higher level of Vitamin D as in the UK sunlight is somewhat less.

Michael Dobson | 04/09/2013

I take the 800IU daily and class it as an essential vitamin for all year round! I usually increase to 5000IU when the clocks go back and the nights draw in! I also never get a cold which I put down to optimum vitamin D3 levels!

G Berlandi | 03/09/2013

I suffer with seasonal affective disorder, and it's especially bad in the winter months; since i've been taking d3 i've been able to stop taking st john's wort and I'm keen to see how it will work once the weather really starts to turn grim.

Hannah Wheater | 16/08/2013

I take a Bio-vitamin D3 capsule every morning. They are small and very easy to swallow. While I try and get out in the sun as much as I can, I take Bio D3 capsules all year round to protect my bones and keep colds and flu away.

Jason Eastham | 16/08/2013

Taken vitamin D for one and half years, had less colds and flu. Joints do feel less pains.

Nora Mynott | 16/08/2013

Taken because we don't get enough sunshine.

Iona Auchterlonie | 16/08/2013

I take PN vitamin D3 800IU twice daily. I Know that vitamin D3 is beneficial for bone health and is particularly good helping to fight against osteoporosis as I go through the menopause. PN product is a nice small capsule, easy to swallow and a very competitive market price.

W McMahon | 20/05/2013

My wife and I are 60 plus, we run, walk and generally enjoy life. Since starting on the pharma nord vitamins we have not had a cold or bug all winter.

M. Periklis | 06/06/2012

Eventually I came across Pharma Nord's D3 and after experimenting with so many, am finally very happy with the exceptional quality and this is the one I will keep on taking.

P Hudson, County Durham | 19/07/2011

As a new mother I have been coming down with anything my little one catches and I have had more colds recently than ever. My local health food shop recommended Pharma Nord's Bio-Vitamin D3 as it is an anti-viral. I usually take vitamin C, but I switched to taking 4 'D-Pearls' a day while ill and my symptoms were less severe and gone within a couple of days.

I hate pills normally, but these are tiny and contain organic olive oil too. Most of the time I take 1-2 and I never miss a day out in the winter. Highly recommended!
