Taking 1.0 gram (1000 mg) of magnesium glycinate daily is substantially higher than the recommended daily allowances (RDA) of magnesium. For adults, the RDA is generally around 400-420 mg for men and 310-320 mg for women¹².

The Tolerable Upper Intake Level (UL) from supplements is 350 mg per day, as excess can cause adverse effects like diarrhea, nausea, and cramping³⁴. Magnesium glycinate may be better tolerated than other forms, but it's still important to adhere to guidelines⁵.

Taking such a high dose of magnesium should be done only under the guidance of a healthcare professional, especially considering factors like existing health conditions or other medications⁵.
