Five Critical Nutrients for Athletes
30 Apr 2008

The nutritional demands of active people are really not that different from sedentary people, except in quantity.  We all need vitamins, minerals, proteins, fats, and carbohydrates all the time.

Calcium

Women need calcium.  We hear it.  We read it. It is now general knowledge.  Less known is that men need calcium just as much as women.  Of course calcium is critical for bone density, but to the body, bone density is not as important as preserving blood levels of calcium to ensure regular heart rhythm and proper nerve and muscle function throughout the body. Sadly, milk and dairy products are nor bio-available sources of Calcium.

There are several types of calcium available.  Which one is best?  I don't believe the human body is capable of properly digesting and assimilating dolomite (rock), carbonate (chalk), or oyster shell calcium.  Bone meal (certified lead free) and calcium citrate are two of the more popular and bio-available forms.  Antacids are not good to use as a calcium supplement.  They lack the necessary magnesium, and often contain coal tar, sodium, and food colouring, and are usually the carbonate form.  (If heartburn is a frequent symptom, antacids are not the answer.  Speak with an herbalist to learn about dietary changes and herbs to strengthen the digestive system to remove the cause of the problem.)

Magnesium, while not officially one of the top five nutrients, is absolutely necessary for proper calcium utilization.  Various sources site proportions ranging from of two parts calcium, one part magnesium to equal parts calcium and magnesium.  In truth, it depends on what the bowel will tolerate.  Magnesium tends to activate the bowel.  To meet the needs for Calcium, Magnesium, (and vitamin D to help with assimilation) I recommend CalMag Plus D.

Vitamin B Complex

The B vitamins are water-soluble vitamins which are critical for every nerve function and most metabolic functions in the body.  These vitamins must be replaced frequently as they are not easily stored.  When the body is under stress it uses the B vitamins much more quickly.  Exercise is a stress on the body, albeit a good stress, and as such, the demands for B vitamins soar.  This family of vitamins includes thiamin (B1), riboflavin (B2), niacin or niacinamide (B3), pyridoxine (B6), cobalamin or cyanocobalamin (B12), folic acid, pantothenic acid (B5), biotin, choline, inositol,  and PABA. Stress Formula neatly meets these needs, and more!

eat large amount of  raw egg white, extended use of antibiotics or sulfa drugs

Choline

transport and metabolism of fats, prevents accumulation of abnormal quantities of fat in liver, optimum nerve function

 

Inositol

digestion and absorption of fats, facilitate uptake of fatty acids, prevents accumulation of abnormal quantities of fat in liver

 

PABA

metabolism of protein

 

Vitamin C

This vitamin, well-known for its beneficial action in the immune response, is less well-known for it's importance in helping people cope with physical and mental stress.  Vitamin C is depleted when there is injury to the body and is always required by the adrenal glands to create stress-coping hormones.  The growth, repair, and maintenance of most body tissues is significantly enhanced with Vitamin C as is the absorption of non-animal source iron.

Certain anti-aging qualities have been attributed to Vitamin C, largely because of its antioxidant properties.  It is felt in the scientific community that free radicals damage body tissues, including the circulatory system.  It is known that Vitamin C, as well as several other vitamins, neutralize antioxidants and thus protect body tissues from damage.

Dr. Lendon Smith recommends taking Vitamin C to the bowel tolerance level, that is the amount that produces soft but not loose bowel movements.  People with inflammatory bowel conditions may not be able to used vitamin C in and type of 'large' quantity.

Vitamin C is best assimilated when taken with bioflavonoids. Vitamin C is included in Stress Formula or can be taken as Vitamin C 500.

Vitamin E

This important antioxidant vitamin has been shown to slow the effects of aging by lengthening the useful life of cells within the body.  When deficient, lung, heart, liver, and blood cells weaken.  It is also believed that Vitamin E can enhance the ability of the blood cells to carry oxygen.

Vitamin E comes in many chemical forms, and understanding this is important.  The fine print on the bottle will usually include the following information.  The vitamin will either be d- or l- .  This indicates, in oversimplified terms, whether the vitamin is natural or synthetic.  D- is natural, l- is synthetic.  The next part of the chemical name will probably be alpha.  Vitamin E, like so many other vitamins, is really a complex vitamin.  That is to say alpha is one part of the complex, and the other parts are beta, gamma, and delta.  Vitamin E is utilized more efficiently in the body when the entire complex is present.  The last part of the name, which is quite universal is tocopherol which translates to 'life giving'.  So, the ultimate vitamin E supplement would include all of the following: d-alpha tocopherol, d-beta tocopherol, d-gamma tocopherol, and d-delta tocopherol. A good mixed d-tocopherol is Vitamin E with Selenium (and why not get that extra little anti-oxidant boost from Selenium).

Iron

Of course, iron had to make it onto the 'top 5' list.  Iron enables blood cells to carry oxygen to body tissues and is needed for energy formation.  When deficient, symptoms may include listlessness, fatigue, irritability, difficulty swallowing, pallor, heart palpitations upon exertion and a general sense of unwellness.   Indications of low iron include inability to concentrate, poor endurance, intolerance to cold, and poor immune response.  Runners tend to be iron deficient, as do menstruating women.  Iron deficiency is said to be the most prevalent deficiency affecting the human population today.

One study, reported in The Real Vitamin and Mineral Book indicated that chronically fatigued women whose iron levels tested in the normal ranges responded well to an iron supplement that increased their testable iron to above average levels.

Ferrous gluconate is one of the most easily assimilated forms of iron.  It is even more well absorbed in the presence of vitamin C, hence, Iron with Vitamin C is a good choice!
