The Importance of Vitamin D3 Compared to D2
Are you aware of the importance of Vitamin D?
Did you know that in England alone 10 million are deficient in vitamin D intake? That’s 15% of the population!
In fact the Public Health England government department recommends that the population take a vitamin D supplement.
However, it may not be quite as simple as just taking a vitamin D supplement, sure, it is probably the best advice to reach out to the majority of the population but there are a number of differing factors such as:
- D3 or D2
- Dosing schedule
These different factors can make a considerable difference to the way vitamin D supplements affect your body.
Why Is It Important?
Vitamin D is often overlooked or not even considered, especially compared to vitamin C.
Yet, vitamin D is extremely important for a number of bodily functions such as:
- Cognitive function
- Bone health
- Organ health
- Nerve health
And it isn’t just the population of England that is suffering a deficiency either, the US and other parts of Europe could be up to two thirds deficient. Even higher in some parts of the world.
Yes, that’s correct, there are two types of vitamin D.
It is a common conception that D3 is the best form of vitamin D to supplement as it is absorbed better.
D3 comes from sunlight plus some foods such as eggs (yolk) and oily fish.
Whereas D2 is produced by plants such as mushrooms.
Regardless of which side you fall on, the it hasn’t been an exact science as to whether D2 or D3 is the better option for supplementation.
This is down to the fact that every person is different and what may work exceptionally well for one person may not be replicated for another.
Therefore absorption data results have been skewed by a persons BMI, pre existing Vitamin D levels, gender plus how often they may already supplement with vitamin D.
a recent study conducted by the BioMed Central (BMC) illustrated that both forms of vitamin D are effective at increasing the levels of vitamin D in the body.
This is measured by levels of 25-hydroxy D found in the body.
The study included 279 adults over a period of 140 days who received varying regimes of either vitamin D2 or D3.
Interestingly BMI seems to affect the responsiveness of D2, whereby D3 was the better and more effective option.
Females also responded better to vitamin D supplementation.
D2 is particularly more effective than when dosed daily as opposed to a 2 week or a 4 week regime, yet D3 is better absorbed in the 2 weekly and 4 weekly regimes than D2
Therefore, it is confirmed that vitamin D supplementation is not quite as clear cut as people would hope.
What is clear though is that, supplementation of either will be effective and will increase the levels of 5-hydroxy D which is required for improved bodily function and health.
