Vitamin D3 Supplements

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.

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.

Pharma Nord recommends the following... 

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

1000IU - 1-5 capsules per day, or as directed 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.

Recommended Daily Allowance (RDA)

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 RDA is not enough').

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.
