What Is Vitamin D3 And What Does It Do?

Take a look at our video below to learn more about Vitamin D!

Vitamin D3 is produced naturally in the skin when it is exposed to sunlight, hence its nickname the ‘Sunshine Vitamin’. Although classified as a vitamin, D3 transforms into a hormone within the body. In this form, it is circulated in the bloodstream to help in the absorption of calcium and phosphorous that is received from digested food sources.

Calcium is used for building and strengthening teeth and bone mass and is vital for bone development and growth. It can be stored in the body tissue until it is required. In addition, Calcium also has a role to play in the production of hormones in the body by transmitting nerve impulses to the brain. Almost 99% of your Vitamin D supply is used for regulating the calcium in the body; the remaining part is utilised for strengthening the immune system and maintaining muscle strength.

Some controversy has arisen whether Vitamin D2 is as active as vitamin D3 when it is ingested, but the consensus is that D3 is two to three times as potent in raising the level of 25-hydroxycholecalciferol (the chemical name for Vitamin D3).

 

Where does Vitamin D3 come from

Vitamin D comes from three major sources:

The Sun

Four major factors determine the effect of sunlight on your vitamin D level:

Time of year – in the summer, the sun’s rays are more direct and direct rays are more effective in raising your skin’s production of vitamin D.

Your Latitude on the Earth – if you are closer to the equator then you will get direct sunlight for a longer time each day and for more months out of the year.

Obstacles to sun exposure of your skin – Whether it be clouds, dark skin colour, smog, a hat, an umbrella, or suntan lotion, anything that limits the exposure of your skin to ultraviolet light significantly reduces your production of vitamin D in the skin.

Altitude – the higher you are, the less atmosphere there is to block the sun’s rays. 

Food

Vitamin D is a fat-soluble vitamin that that dissolves in oil and not in water. This means that oily foods like wild salmon, cod liver oil and mushrooms are the best sources of vitamin D.

Supplements

If you can’t get enough vitamin D from your diet, you can get all the vitamin D you need from supplements.

What is a healthy level of Vitamin D3?

Nutritional adequacy for Vitamin D is based upon the measurement of the metabolite 25-Hydroxyvitamin D. Leading experts recommend that 25-Hydroxyvitamin D concentrations should be at least 75-80 nmol/L (30-32 ng/mL).

Dosage Guidelines

The new recommended levels of 25-hydroxyvitamin D can be achieved with the administration of daily doses of Vitamin D3 that are substantially higher than those found in common multivitamins and calcium supplements.

Considering trials and research, it is recommended that to maintain the correct levels of 25-Hydroxyvitamin D, one or two SunVit-D3 1000 IU Tablets are taken per day with the main meal. Once the body has the correct levels of 25-Hydroxyvitamin D, it will flush out any that is not needed.

Higher strength doses can be taken weekly, however, we strongly recommend that you first seek medical advice before taking higher doses.

Fatty fish, vitamin supplements and calcium supplements containing Vitamin D can all be taken along with SunVit-D3 without any major risk of Vitamin D overdose (see FAQ –Can I overdose on SunVit-D3). The safety of daily doses ranging from 25 to 200 µg (1000-4000 IU) has also been documented.
