Score 65
An extremely affordable magnesium oxide supplement with a small calcium addition, primarily for basic mineral support or digestive regularity.
Analysis
This product delivers 250mg of elemental magnesium from magnesium oxide and 65mg of elemental calcium from calcium carbonate. Magnesium oxide has a high elemental magnesium content, but its systemic absorption is often lower than other forms, making it a common choice for occasional constipation relief. The added calcium is a minor amount, contributing to overall mineral intake.
As a very low-cost option, it serves as a basic mineral supplement for those prioritizing affordability. The tablet form is standard and the high review count indicates its widespread use, likely driven by its value proposition.
Pros
- Exceptionally low price per serving, making it extremely budget-friendly.
- Provides a substantial 250mg dose of elemental magnesium.
- High number of customer reviews, indicating widespread popularity and use.
- Includes a small amount of calcium for complementary mineral support.
Cons
- Magnesium oxide has lower bioavailability for systemic absorption compared to other magnesium forms.
- Known to have a significant laxative effect, which may be undesirable for some users.
- Tablets may be large and potentially difficult to swallow for some individuals.
- The small amount of calcium may not be significant enough for those with higher calcium needs.
Warnings
- Magnesium oxide can cause significant laxative effects, including loose stools or diarrhea, especially at this dose.
- Individuals with sensitive digestive systems should start with a lower dose or consider a different form of magnesium.
- Consult a healthcare professional before use if you are pregnant, nursing, taking medications, or have a medical condition.

Goals
Impact
Highest effect
Magnesium oxide is well-known for its potent laxative effect and is often used to relieve occasional constipation due to its ability to draw water into the bowel. It is highly effective for this specific purpose.
Impact
High effect
Magnesium is crucial for bone health, and this product provides both magnesium and a small amount of calcium. However, the lower absorption of magnesium oxide may limit its optimal contribution to bone density compared to other forms.
Impact
High effect
As a very economical way to get magnesium, it contributes to meeting basic mineral needs. However, the form's lower absorption for systemic benefits means it's not the most comprehensive option for general health.
Impact
Moderate effect
While magnesium supports heart health, the lower systemic absorption of magnesium oxide means it may be less effective for this purpose compared to more bioavailable forms. It offers foundational, but not optimal, support.
Impact
Moderate effect
Magnesium does contribute to cardiovascular function, but the magnesium oxide form may offer less direct systemic support than more absorbable forms. Its impact here is more general than targeted.
Impact
Moderate effect
Magnesium is essential for muscle function and energy, but the lower systemic absorption of magnesium oxide might limit its effectiveness for optimizing athletic performance and recovery compared to other forms. It provides basic support.
Impact
Moderate effect
Magnesium is key for energy production, but the lower systemic absorption of magnesium oxide may mean less efficient utilization for cellular energy pathways compared to other forms. It provides fundamental support.
Impact
Moderate effect
Magnesium can promote relaxation, but the potential laxative effect of magnesium oxide might interfere with sleep rather than enhance it for some individuals. Its sleep benefits are generally indirect and mild.
