insightsAnalysis

NOW's Calcium & Magnesium offers a blend of magnesium forms (Oxide, Ascorbate, Citrate) and calcium forms (Ascorbate, Carbonate, Citrate) in very high quantities. Based on the ingredient listing, this product delivers 1500mg of elemental magnesium and 3g of elemental calcium per serving, which is an exceptionally high dose for daily use.

This combination is designed to provide comprehensive support for bone health, muscle function, and nerve transmission. The inclusion of magnesium citrate and oxide can also contribute to digestive regularity. However, the very high doses of both minerals mean it is likely intended for specific or short-term applications under guidance, rather than routine supplementation.

thumb_upPros
  • Provides a very high dose of both calcium and magnesium.
  • Includes multiple forms of each mineral for varied absorption and effects.
  • Extremely affordable price per serving.
  • Can support bone health and muscle function comprehensively.
thumb_downCons
  • Exceptionally high dosages of both calcium (3g) and magnesium (1.5g) per serving.
  • Magnesium oxide, a component, has low bioavailability for systemic effects.
  • High doses of magnesium, especially oxide and citrate, can cause significant laxative effects.
  • High calcium intake can interact with other minerals or medications.
warningWarnings
  • The very high doses of calcium and magnesium can cause digestive upset, including diarrhea.
  • Consult a healthcare professional before taking due to the extremely high dosages, especially if you have existing health conditions or take other supplements/medications.
  • Do not exceed recommended serving without professional guidance, as excessive mineral intake can have adverse effects.

flagFitness
Impact
Moderate effect
Magnesium is vital for muscle contraction and energy, and calcium for strong bones, both important for fitness. However, the extremely high doses may not be practical or beneficial for routine fitness supplementation.

flagDetoxification
Impact
Moderate effect
The magnesium citrate and oxide forms can provide a strong laxative effect, which some individuals associate with bowel cleansing and 'detoxification.' It can help clear the digestive tract.

flagGeneral Health
Impact
Moderate effect
While providing essential minerals, the exceedingly high dosages of both calcium and magnesium in a single serving make this product less suitable for general daily health maintenance. A more balanced, lower-dose product is typically preferred for routine support.

flagEnergy
Impact
Moderate effect
Magnesium is essential for ATP production and energy metabolism. However, the extremely high doses, particularly with the inclusion of laxative forms, may not translate to sustained energy benefits for everyday use.

flagSleep Support
Impact
Moderate effect
Magnesium can help relax muscles and calm the nervous system, potentially aiding sleep. However, the very high dosage and the inclusion of stimulating calcium may not be optimal for promoting restful sleep in all individuals.

flagStress Relief
Impact
Moderate effect
Magnesium contributes to regulating the body's stress response. While it may have some calming effects, the extremely high overall mineral load might overwhelm the system rather than provide balanced stress relief for daily use.

Magnesium 62
This product provides a very high amount of magnesium from multiple forms, including citrate and oxide, along with significant calcium. While offering broad mineral presence, its exceptionally high dosage for both minerals means it's not a typical daily magnesium supplement and requires careful consideration of individual needs and potential side effects.
