Muscular Strength and Vitamin D

Optimizing your vitamin D3 level is one of the most important things you can do to improve your overall health and physical performance.    

Vitamin D3 controls or influences almost every cellular process in the body.  It regulates more than 2,000 of the 30,000 human genes.  It's essential to endocrine function, controlling the action of the adrenal and anabolic hormones, the growth of cells, and the production of enzymes.  It's a powerful immune booster, providing front-line defense against illness and disease.  And if you're an athlete, vitamin D3 is essential for peak, physical performance; it contributes to muscular strength and recovery while controlling physical reaction time, balance, and coordination. 

A few months ago, I shared information on new research from the Journal of Sports Science 
that showed a link between high vitamin D3 levels and improved speed and agility.  Now, even more recent research published in the March, 2013 issue of The Journal of Clinical Endocrinology & Metabolism suggests that... 

Assess Yourself for Optimal Performance.

If you're a dedicated athlete who works hard to become fitter, faster and stronger, it's important to realize that solid and lasting performance gains need to happen from the "inside out."  While external performance analysis—V02 max and lactate threshold tests—can be useful, they don’t provide any useful insight into the physiological processes at work inside an athlete’s body; into the internal mechanisms responsible for those hard-earned, end results.

Ask yourself the following questions:

How well does your body transport oxygen from the lungs to your muscles?  Does it digest proteins and utilize carbohydrates as effectively as it should?
Has your performance started to decline or hit an immovable plateau? Do you have difficulty recovering after a hard effort?  What is your body trying to tell you?

There’s no need to guess.  Measuring and evaluating your body’s physiological performance potential can be done easily and inexpensively, in the comfort and convenience of your own home, with the series of laboratory-based assessments made available by Core 4 Nutrition.... 

What is the Best Multivitamin?

If you’re like most people, you compare prices before deciding on which product or service you want to buy.  But when it comes to deciding on the best multivitamin take, quality counts—you get what you pay for.  Although the inexpensive prices of the multivitamins sold by major retailers are tempting, there are a number of things you should know about these products.

The vast majority of all multivitamins are made out of cheap, synthetic, chemical isolates that claim to promote health, but don't.

You can typically identify a chemical isolate by its two-part name. For example: 
thiamin HCL, tocopheryl succinate, ascorbic acid, calcium carbonate etc.  If you are taking a multivitamin with a list of ingredients like this, you’re better off not taking it at all!

The problem is that...

Vitamin D: Sun or Supplements?

This is an important summer reminder that while supplementing with a high-quality, sublinqual Vitamin D3 spray is essential, budgeting some time for some unprotected, full-body sun exposure can be very beneficial to your overall health and performance, too.  In fact, recent studies imply that sun exposure is the best (although not always viable) option; taking even the most effective of vitamin D3 supplements cannot fully replace the benefits of real sun exposure. 

Dr. Prue Hart of the University of Western Australia makes these points in a recent paper (Hart PH. Vitamin D Supplementation, Moderate Sun Exposure, and Control of Immune Diseases. Discov Med. 2012 Jun;13 (73): 397-404).  She concludes that, “It is possible that moderate sun exposure and vitamin D supplementation may be complementary for maximal control of immune-driven diseases.”

She also emphasizes that over the past two decades, world-wide vitamin D levels have fallen about twenty percent while the incidence of immune system diseases, such as multiple sclerosis, type 1 diabetes, and asthma have all significantly increased.  Dr. Hart cites additional evidence which suggests....
