HbA1c (usually read as “hemoglobin A1c”): “They say that, basically, you age at the rate you produce insulin. HbA1c will tell me what was the average insulin over the last 3 months…. I’ve found over the years that, actually, the amount of magnesium, supplemental magnesium, you consume, is the fastest way to drop that value. So magnesium is probably one of the best anti-aging minerals.”
