WHY YOU SHOULD TAKE VITAMIN D3 INSTEAD OF D2

As a chiropractor, I am repeatedly asked about the benefit of calcium and vitamin D supplementation.  I thought the following information would be of great interest for many of my patients and others suffering from chronic pain, sleep disorders, and osteoporosis among many other conditions associated with vitamin D deficiency.

Health authorities around the world are being urged to rethink their recommended protocols around vitamin D supplementation following the publication of a groundbreaking study which indicated vitamin D2 and D3 do not have the same nutritional value.  Current guidance given by a number of government bodies around the world states that the two forms of vitamin D are equivalent and can be used to equal effect.

In this new study1, vitamin D levels of 335 South Asian and white European women were assessed over two consecutive winter periods. The women were split into five groups, with each group receiving a placebo, a juice containing vitamin D2 or D3, or a biscuit with vitamin D2 or D3.

The results revealed that vitamin D3 was twice as effective in raising levels of the vitamin as D2, with vitamin D levels in women who received vitamin D3 via juice or a biscuit increasing by 75% compared to those who were given D2 through the same methods. Those given D2 saw an increase of 33% over the course of the 12-week intervention. Those who received the placebo experienced a 25% reduction in vitamin D levels over the same period.

This is particularly of great interest to chiropractic community as other researchers have recently uncovered that vitamin D supplementation combined with good sleep hygiene may not only help in sleep disorders but may also be beneficial in the prevention and treatment of chronic pain conditions2.  Also prenatal vitamin D supplements have now been shown to positively modify the immune system of neonates, which could help to protect against asthma and respiratory infections in infants3.

The take home message here is the fact that if you are taking vitamin D supplement, make sure it is from the D3 variety as it is much more effective in raising your blood vitamin D levels.

WEIGTH TRAINING THE HEALTHY WAY

 Light weights, many repetitions effective at building muscle mass.

New research is challenging traditional workout wisdom which says that heavy weight lifting is the best way to build muscle.
In the latest results from a 16-year study by McMaster University in Hamilton, Ontario, lifting lighter weights many times was found to be as efficient as lifting heavy weights for fewer repetitions.

In the study, two groups of experienced male weight lifters followed a 12-week, whole-body protocol. One group lifted lighter weights (≥50 per cent of maximum strength) for sets of 20-25 repetitions. The other group lifted heavier weights (≥90 per cent of maximum strength) for 8-12 repetitions. Both groups lifted to the point of failure. Gains in muscle mass and muscle fiber size were virtually identical in both groups.

It appears that fatigue is the great equalizer. At the point of fatigue, both groups would have been trying to maximally activate their muscle fibers to generate force. Lift to the point of exhaustion and it doesn’t matter whether the weights are heavy or light.

The findings are published online in the Journal of Applied Physiology:http://jap.physiology.org/content/jap/121/1/129.full.pdf
