Compare magnesium labels: elemental amount, form and serving
The milligram number on the front of a magnesium bottle may describe a different basis from its Supplement Facts panel. Start with the declared magnesium row and the serving size, then inspect the chemical form.
What to compare on the label
Use the magnesium amount from Supplement Facts, not the mass of the entire compound. A declaration can name a 2,000 mg compound while listing 200 mg magnesium.
Keep glycinate, citrate, oxide and other forms visible. Our shared magnesium row compares declarations; it does not rank absorption or tolerability.
Two tablets per serving means a 200 mg serving is not a 200 mg tablet. Only derive per-tablet amounts when the label clearly states the number of identical tablets.

Keep uncertainty visible
A missing amount means it is not disclosed in this captured record, not that the ingredient amount is zero. Do not add parent blend totals to their nested components. Check the current source label for warnings, other ingredients and directions before making a purchase.
