No major underlying issues going on; I am just more sensitive to chemical imbalances for whatever reason.
edit- I should clarify, as I don't want to make it sound like I am against Vitamin D supplementation. I am simply more susceptible to palpitations when there is some form of chemical imbalance in my body - excess calcium seems to be a trigger for me, but there are other factors, such as low potassium etc...

Different people respond differently to any chemical - a dose that is perfectly safe for one person could have an adverse effect on someone else. It's actually really hard to come up with generally recommended dose ranges for the entire population for substances that have beneficial effects at lower doses and adverse effects at higher doses, because there can be overlap in the distributions where one person might be helped by (or even need) an amount that harms someone else.
