2g Vitamin C Ameliorate Low Testosterone Levels and Sexual Dysfunction in Diabetic Rats. Usefulness in Normoglycemic Individuals Still Questionable.
|Illustration 1: In view of the increase in renal |
vitamin C clearance with higher plasma levels
(Friedmann. 1940), it may be sensible to use a
time-released vitamin C formula, or, even
better, eat a serving of veggies or fruits that
are high in vitamin C multiple times a day
In their study, the Fernandez et al. had fed 10 out of 20 hyperglycemic rats vitamin C enriched chow (+150mg) and found that the addition of the water-soluble vitamin had beneficial effects on oxidative strees biomarkers in the erythrocytes, which have proven to be a valuable indicator of stress levels for the whole body (Naziroğlu. 2001; Garg. 2000)] (cf. figure 1),

[...] the present study showed that vitamin C supplementation minimized some alterations in the male reproductive system caused by hyperglycemia such as reduction of testosterone and LH levels and impairment in sperm morphology. [italicization by Dr. Andro]After all, what's the worth of a "minimizing" the negative effect on testosterone levels to -71%? This may be 10% less damage than without vitamin C, but wouldn't it be much better not to get yourself into such a misery in the first place?
Note! Not everything that is good for sick people makes a viable addition to the supplementation regimen of a healthy or even athletic person. Even Fernandes and her co-workers emphasize that "is possible that the beneficial effects of vitamin C supplementation are only relevant to those individuals with low levels of vitamin C and high levels of oxidative stress that occur in hyperglycemic condition."Well, regular exercise and the avoidance of high fructose corn syrup and the other sweet suspects you poise yourself with on a daily basis would be the way to go - and you know that!
