Interesting - I hadn't paid any attention. I've had afib for over 13 years, it is very well controlled, but I learned it is highly sensitive to extra calcium. I monitor for premature contractions (PAC's & PVC's) with a recording heart rate monitor. Recently noticed they'd increased dramatically. Thought it was because I'd reduced my magnesium intake in half - from 2.4 to 1.2 g/day - I've always controlled my afib with high dose magnesium. Thought the premature contraction increase was due to that and started to increase my mag intake again. Could easily be the calcium - or it could be both calcium increase & mag decrease. Ester C has 100 mg Ca+ / 1000g Vit C. So 2 doses a day is 200 mg Ca+ extra - could be enough to cause me issues.
The Ester C did lower my marginally high Lp(a).
I may switch to sodium ascorbate as I try to get a fair amount of sodium - at least 5 g/day.
