Consumer advice
Magnesium glycinate is a legitimate, well-absorbed form of magnesium with real benefits for sleep and muscle function.

If you're shopping independently, Doctor's Best High Absorption Magnesium Glycinate runs about $20 for 240 capsules on Amazon — same chelated form, similar quality, half the price.

Safety & side effects
What NIH says about the ingredients in this product. This describes the ingredients, not tests of this product, and it is not medical advice. Ask a doctor or pharmacist first if you take medication, are pregnant or nursing, or have a health condition.
Magnesium
Magnesium from food poses no health risk in healthy people, because the kidneys clear the excess. High doses from supplements or medications can cause diarrhea, nausea and abdominal cramping, and very high doses can lead to toxicity.
Possible side effects
- High doses from supplements or medications can cause diarrhea, nausea, and abdominal cramping.
- Magnesium carbonate, chloride, gluconate, and oxide are the forms most commonly reported to cause diarrhea.
Serious risks
- Very high doses can lead to magnesium toxicity, with low blood pressure, vomiting, difficulty breathing, irregular heartbeat, cardiac arrest and other signs.
- A few cases of fatal hypermagnesemia have been reported.
- Very large doses of magnesium-containing laxatives and antacids have been associated with magnesium toxicity.
- The risk of toxicity increases with impaired kidney function or kidney failure.
Avoid or ask a doctor first if
- People with impaired kidney function or kidney failure face higher risk of magnesium toxicity.
- People taking medications regularly should discuss their magnesium intake with their health care providers.
Medication interactions
- Magnesium may interact with oral bisphosphonates, tetracyclines, and quinolone antibiotics.
- Some medications, including diuretics and proton pump inhibitors, can affect magnesium status.
Upper limit: 350 mg a day for adults 19+. This label lists 120 mg.

Vitamin C
The source describes vitamin C as having low toxicity, with high doses mainly causing digestive upset. It names a few specific concerns, including kidney stones, iron overload in people with hereditary hemochromatosis, and a possible pro-oxidant effect.
Possible side effects
- The most common complaints are diarrhea, nausea, abdominal cramps, and other digestive upset.
Serious risks
- High intakes may raise urinary oxalate and uric acid, which could contribute to kidney stones, especially in people with renal disorders.
- The best evidence that vitamin C contributes to kidney stones is in patients who already have hyperoxaluria.
- In people with hereditary hemochromatosis, long-term high doses could worsen iron overload and cause tissue damage.
- A few in vitro studies suggested that supplemental oral vitamin C, acting as a pro-oxidant, could cause chromosomal or DNA damage and possibly contribute to cancer.
- In postmenopausal women with diabetes in the Iowa Women's Health Study, supplemental vitamin C of at least 300 mg/day was significantly associated with a higher risk of dying from CVD.
Avoid or ask a doctor first if
- People with hereditary hemochromatosis face a concern about iron overload with chronic high doses.
- The upper limits do not apply to people receiving vitamin C as medical treatment, who should be under a physician's care.
- Infants should get vitamin C only from formula and food.
Medication interactions
- Vitamin C supplements may interact with radiation therapy and with medications, including chemotherapy drugs and statins.
- People taking these medications regularly should talk with their health care providers about vitamin C intake.
Upper limit: 2000 mg a day for adults 19+.
