“Slight Edge Performance Program”: Alarming Vitamin D Deficiencies in NFL Football Players

According to a study presented at the American Orthopaedic Society for Sports Medicine 2011 Annual Meeting, vitamin D deficiency might be unusually high among American football players, with black players and players who have suffered muscle injuries showing significantly lower vitamin D levels.

According to the study, researchers tested the vitamin D levels of 89 professional football players from the New York Giants National Football League (NFL) team in the spring of 2010 and found that 27 players (30.3%) had deficient vitamin D levels (below 20 ng/mL). As many as 45 players (50.6%) had levels consistent with vitamin D insufficiency (between 20 and 31.9 ng/mL). Only 17 players (19.1%) had values within normal limits (above 32 ng/mL).

Lead author Michael K. Shindle, MD, an orthopaedic surgeon from Summit Medical Group, in Berkeley Heights, New Jersey said, “We found that an alarming percentage of players — 80.9% — had abnormal vitamin D levels of less than 32 ng/mL.”

Dr. Michael K. Shindle added that all players sustaining injuries that caused them to miss at least 1 practice or game had vitamin D levels that were significantly lower than players without muscle injury.

The study done with the NFL’s New York Giants consisted of 31 white players and 58 black players. Blacks tend to have lower vitamin D levels than whites in the general population. “Up to 93% of African American players had abnormal vitamin D levels, compared with 31% of white players,” Dr. Shindle said.

What is Vitamin D?
Vitamin D is an essential vitamin required by the body for the proper absorption of calcium, bone development, control of cell growth, neuromuscular functioning, proper immune functioning, and alleviation of inflammation.

Why is Vitamin D important for good health and athletic performance?
Dr. Shindle says, “It’s also been shown that vitamin D can increase the number of type II, or fast twitch, muscle fibers.” This is very important for athletes who want to get faster and increase their speed.

According to a 2009 study published in “Medicine and Science in Sports and Exercise,” maintaining proper levels of vitamin D helps your body to properly use calcium, a mineral required for proper functioning of your muscles, including fast twitch muscle fibers. Consuming vitamin D can increase the number of fast twitch muscle fibers within your muscle tissue, as well as increase the size of these fibers. Overall, this translates to an increase in athletic performance.

Inadequate levels of vitamin D can lead to a weakened immune system, increased cancer risk, poor hair growth, and osteomalacia, a condition of weakened muscles and bones.

Other Benefits of vitamin D?
•It is crucial for the absorption and metabolism of calcium and phosphorous which help support and maintain healthy bones.
•It is an immune system regulator.
•It may be an important way to arm the immune system against disorders like the common cold.

What is the best way to get vitamin D?
Vitamin D for humans is obtained from sun exposure, food and supplements. Sunlight promotes sufficient vitamin D synthesis in the skin. Foods that contain vitamin D include fish oils, fatty fish, beef liver, cheese, egg yolks, and certain mushrooms.

Personally I have been taking a plant based food supplement called NUTRILITE® DOUBLE X® since my college football days at Virginia State University. I noticed how I had more energy to train harder and workout longer. I also found that my body was recovering faster from workouts and competition. My friend Amanda is a former college soccer player and in 2008 she recommended that I use it to fill all my nutrition gaps. She said Double X was the best and in my personal opinion she was telling the truth! NUTRILITE® is the world’s leading brand of vitamin, mineral, and dietary supplements. It’s formulated by NUTRILITE, the only global vitamin and mineral brand to grow, harvest, and process plants on their own certified organic farms.**

When you compare NUTRILITE DOUBLE X® to Centrum® and GNC Solotron®, there’s really no comparison! Double X contains more of almost every vitamin and mineral, plus many more plant concentrates, which provide superb antioxidant protection.

Why do I need a supplement?
The American Medical Association recommends that all adults take one multivitamin daily. This is true even if you already eat a diet rich in fresh, whole, natural foods, because the foods you consume often don’t supply all the vitamins and minerals you need, at the recommended levels. If you’re going to supplement, why not start with the world’s best multi? NUTRILITE® DOUBLE X® Vitamin/Mineral/Phytonutrient.

World-class Olympic sprinter and former world’s fastest man Asafa Powell is the perfect example of an elite athlete who plant based supplementation made a tremendous difference for and the reason for that is he was now provided with the nutrients he needed to operate at maximum efficiency.

Asafa Powell broke the world record for the 100-meter sprint in June 2005, three months after adding NUTRILITE™ DOUBLE X™ to his training regimen.

In 2005, the then 22-year-old Asafa Powell broke the men’s 100-meter world record at a meet in Athens, Greece becoming the world Record holder in the 100-meter sprint — just three months after his brother introduced him to NUTRILITE DOUBLE X. Asafa’s brother Donovan, who also was a world-class sprinter, was introduced to the NUTRILITE brand by his wife’s parents. Appreciating the benefits he received from DOUBLE X, Donovan supplied the multivitamin to his younger brother when he complained of low energy levels during his training early in 2005.

“Taking DOUBLE X was the only change I made to how I had been training,” says Asafa. “After I started taking it, I felt I had more energy to train harder and run faster. I am very careful about what I consume so I appreciate the balanced vitamin and mineral content plus the rich, all-natural plant concentrates in DOUBLE X.”

The world class runner said: “When I run, I don’t think about anyone else. I don’t think about my competition, I just do what I have to do. Nutrilite is a lot like me that way, because they don’t consider the competition in what they do, they just focus on being the best in their field,” he says. “I am confident that DOUBLE X and NUTRILITE will help me power up for the competitions yet to come.”


NSF Certification Addresses Athletes’ Fear of Unknowingly Testing Positive for Banned Substances.

NSF International’s Certified for Sport® program reduces the risk that a dietary or sports supplement contains banned substances. Recognized by Major League Baseball (MLB) and the MLB Players Association, National Football League (NFL), Canadian Centre for Ethics in Sport (CCES), the Ladies Professional Golf Association (LPGA) and the PGA, the NSF Certification program responds to the growing demands by athletes, coaches, team owners and others concerned about finding banned substances in sports nutrition products.
