What Is Vitamin D3 And What Does It Do?

Vitamin D3 is produced naturally in the skin when it is exposed to sunlight, hence it’s 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 blood stream 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.

Muscle and Bone Strength Vitamin D Benefits

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).


SunVit-D3 Vitamin D – The Science

With the introduction of SunVit-D3, Sunvit-D3 Limited has set a new scientific standard for preparations sold as health supplements.

SunVit-D3 has excellent bioavailability in the oral supplement sector; the unique composition and quality of SunVit-D3 Vitamin D3 preparations have, in recent studies, been shown to be essential for the bioavailability of the compound.


SunVit-D3 Vitamin D Is Safe and Efficient

SunVit-D3 Vitamin D3 is currently the only Vitamin D3 supplement with substantial scientific evidence on both efficacy and safety. With the introduction of SunVit-D3 preparations, Sunvit-D3 Limited can provide customers with one of the most superior products available.


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.
