@eleanork Sorry to be so late in answering . Seems my cell phone and laptop don''t like each other I get post on one but not the other . Anyhow the mag malete doesn't take long to accumulate in the system . I take during the day and split in evening about 600 mg. Especially at night keeps RLS away from me . A fibro group I belonged to awhile ago said we need more mag. then most people and for me its mag. malete . Ive tried oxide and it didn't do anything for me . Take care
