Questions before you buy
Are magnesium glycinate and bisglycinate different?
These names are commonly used for magnesium bound to glycine. For these Thorne products, the practical differences are the format, added ingredients, and elemental magnesium per serving. The label is more useful than the name alone.
Are the powder and packets unsweetened?
No. Both list monk fruit. The capsules do not list a sweetener. If you want to avoid a sweet drink or a particular aftertaste, the capsule format may better fit that preference.
Can I combine the capsules, powder, and packets?
Count magnesium from all supplements and magnesium-containing medications. The NIH adult upper limit from supplements and medications is 350 mg per day unless a clinician recommends otherwise; this limit does not include magnesium naturally present in food.
Does one format work better for sleep?
These labels do not establish that one format is better for sleep. Choose based on your needs, the amount your clinician recommends, and what you can comfortably take.
What if I take medication or have kidney disease?
Ask your pharmacist about timing with medicines, especially certain antibiotics and osteoporosis medicines. Check with your kidney-care clinician before taking supplemental magnesium if you have kidney disease.
Can magnesium cause digestive side effects?
Yes. Supplemental magnesium can cause diarrhea, nausea, or cramping. More is not automatically better; dose and individual tolerance matter.
