Is a glycinate tablet as absorbable as a capsule?
A tablet and a capsule here hold the same form of magnesium: glycinate. NOW’s tablet and Nature Made’s capsule both print 200 mg of magnesium as bisglycinate in 2 pills, so the label amounts match. So choose the tablet for the price or the capsule for the testing list.
Who wants a tablet?
A tablet suits you if you would rather not swallow a capsule shell. Tablets of 100 mg also let you take 1, 2 or 3 at a time. The 7 tablets in the table run from 50 to 325 mg of magnesium a tablet.
How much magnesium should you take?
Take 2 tablets once a day for 200 mg. NIH sets 350 mg a day as the upper limit from supplements and medicines, not counting food. The NOW and Doctor’s Best labels allow a second serving, which would be 400 mg a day. Vitamin Shoppe’s one serving is 400 mg.
