August 2013-Mid-september 2013: continues taking 500mcg of chromium a day and still only has about 1 pimple a day while changing nothing in his diet and mood improves as well as physical ability
Results and Possible explanations:
The acne was reduced because it was somehow being caused by his high carb, high sugar diet. Upon reducing intake of such carbs and sugar, the acne disappeared. However, when taking chromium, a know blood-sugar stabilizing element, his acne stayed at bay while he was able to return to his previous diet and no longer have problems in mood or physical ability possibly caused by the low carb diet.
Conclusion: 500 mcg of chromium a day can substantially help clear acne specifically because of its blood sugar lowering effects and seems to continue working after an extended amount of time.
