Elemental: The magnesium itself; the rest of the compound weight is the partner molecule.
Compound: The whole salt, such as magnesium glycinate, that must physically fit in the capsule.
Size 000: The largest standard capsule, about 1,100 mg of powder at 0.8 g/mL, the top of the usual 0.6–0.8 range; size 00 holds about 730 mg and size 0 about 545 mg.

| Formula re: Contains | This formula contains magnesium in the form of magnesium bisglycinate, where each magnesium particle is bound to two (bis) molecules of the amino acid glycine. This is one of the best researched and most effective forms of magnesium. Magnesium bisglycinate is stable and is particularly well absorbed in the gastrointestinal tract. Magnesium is one of the most important minerals for the human body, and crucial for good health. It is recommended to take at least 345mg of magnesium daily. Magnesium supplementation is therefore important for more people. |
| Suggested/Recommended/Usage/Directions | Recommended Dosage: Adults take 1-2 tablets daily, or as recommended. Best taken with meals. Do not exceed the recommended dosage. |
