Only if that particular tablet is designed to be split. Extended-release or enteric-coated tablets may not work as intended when cut, and an unscored tablet may not divide evenly. Check the product instructions before splitting it.
Half a magnesium tablet is not a proven sleep aid for everyone. Correcting a magnesium deficiency may help if one is present, but research does not show that magnesium reliably improves sleep in people who are not deficient.
You can usually take half a magnesium tablet with or without food. Taking it with a meal may be easier on your stomach if it causes nausea or discomfort; follow the specific product directions if they say otherwise.
Yes, half a magnesium tablet can cause loose stools or diarrhea, depending on its magnesium form and amount. If this happens, stop taking it and check the directions before using it again; some forms are more likely to have this effect.
Half a magnesium tablet may help leg cramps when they are related to magnesium deficiency, but it is not a dependable fix for cramps from other causes. The amount in half a tablet varies by product, so check its label rather than assuming the dose.
There is no set time for half a magnesium tablet to work. The result depends on why you are taking it and whether you have a deficiency; correcting a deficiency is not usually an immediate effect you can expect after one tablet.
Yes, magnesium can reduce absorption of some antibiotics when taken too close together. The spacing needed depends on the specific antibiotic, so ask your pharmacist or prescriber how to time half a magnesium tablet with your medication.
You can take half a magnesium tablet daily only if the product directions and your total intake make that amount appropriate. Half a tablet is not a standard dose across products, since each tablet can contain a different amount of magnesium.
Not necessarily; impaired kidneys may have trouble clearing excess magnesium from the body. If you have kidney disease, ask your doctor before taking half a magnesium tablet, even if the amount seems small.
Yes, half a magnesium tablet can usually be taken on an empty stomach. If it causes nausea, stomach discomfort, or loose stools, taking it with food may be more comfortable; follow the directions for your particular product.

GLYCEMIC INDEX
GLYCEMIC LOAD
Accounts for portion size — a more realistic measure than GI alone.
A half magnesium tablet is one half of a tablet supplement containing magnesium, rather than a food or meal. It is intended to supplement magnesium intake; the form of magnesium and other ingredients can vary by product, so check the label to see how much magnesium is in the portion.
It is generally taken with water, but whether a particular tablet can be split, crushed or chewed depends on its instructions. It has little in common with a food’s taste or texture and contributes very little energy or macronutrients. If you’re using a half magnesium tablet, make sure the product is suitable for splitting and follow its directions or advice from a health professional.
High
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.

An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
