very cool! i am active but not in any way an endurance athlete. i take students on nature hikes up to 10km and that's about my max daily exertion.
i have a friend who is much more athletic and had some pretty serious health problems. i put her on a new diet and supplement regimen and asked her to get some bloodwork done. all the tests came back showing poor values and now that she is on her new regimen some of the most important problems have already resolved. more bloodwork to follow to see how effective the regimen is in supporting. info for you:
Nutrition for Athletes and Most Common Vitamin Deficiencies Among Sportspeople http://www.vitamin-deficiency-today.com ... letes.html
"Prolonged and intense exercise causes athletes to lose significant amount of fluids and many other nutrients in sweat
. To avoid dehydration in the system you need to drink 8 to 16 ounces of water one or two hours before exercising; 4 ounces every 15 minutes during your workout; after workout drink until you’re no longer thirsty.
For rehydration you may chose water or special sport drinks, both are good choice. If you’ll decide to choose sports drinks, just make sure it contains no artificial colors, flavors and preservatives so your body does not get harmful ingredients
Deficiency of B vitamins is widely spread in athletes... Thiamin and riboflavin
are easily lost in sweat, so the more you’re active and sweating the more you need of these two vitamins... Iron deficiency
is the next common nutritional deficiency among athletes. Especially women and vegetarians that are involved in sport are at risk to develop iron deficiency. This mineral is easily lost through sweat...
...minerals such as potassium, magnesium, and zinc
... are also lost through heavy sweating..."
there's a reasonable overlap here between the nutrients lost to exertion and the deficiencies seen in ms patients. potential food for thought.
