Analysis
Sundown's Calcium Magnesium & Zinc supplement aims to deliver these three vital minerals in a single tablet. It includes calcium from carbonate and gluconate forms, magnesium from gluconate and oxide, and zinc from citrate and oxide. These minerals are important for bone structure, muscle function, and immune support among other roles.
A significant concern with this formulation is the high concentration of each mineral per serving. With 2000mg of calcium, 800mg of magnesium, and 50mg of zinc, the dosages generally exceed typical daily recommendations and, for magnesium and zinc, surpass the established upper tolerable intake levels for supplemental use. This could lead to adverse effects, especially with consistent consumption.
While some of the forms like calcium gluconate and zinc citrate offer better absorption, the overall high cumulative amounts raise questions about the product's practicality and safety for general supplementation. Users seeking a balanced mineral intake may find these dosages difficult to manage without risk of overconsumption.
Pros
- Combines three essential minerals (calcium, magnesium, zinc) in one product.
- Includes some forms known for better absorption, such as calcium gluconate and zinc citrate.
- Offers a substantial amount of each mineral, potentially useful for severe deficiencies under medical supervision.
- Price per serving is relatively low.
Cons
- Magnesium (800mg) and Zinc (50mg) dosages are well above the generally recognized safe upper intake levels for supplemental forms.
- The very high Calcium dosage (2000mg) is also significant and could approach the overall tolerable upper intake level when combined with dietary sources.
- Excessive magnesium can cause digestive issues like diarrhea.
- High zinc intake can interfere with copper absorption and lead to other adverse effects.
- The use of magnesium oxide and zinc oxide may offer lower bioavailability compared to other forms.
Warnings
- Consult a healthcare professional before taking this product due to the high dosages of magnesium and zinc.
- Excessive intake of zinc can lead to copper deficiency and gastrointestinal upset.
- High doses of magnesium can cause digestive disturbances such as diarrhea and cramping.
- Individuals with kidney disease or other medical conditions should avoid high mineral supplementation without strict medical guidance.

Goals
Impact
Lower effect
Calcium and magnesium are crucial for bone health, and this product offers high amounts. However, the excessive dosages of both calcium and magnesium could lead to imbalances or adverse effects, making it a risky choice for consistent bone support.
Impact
Lower effect
Zinc and calcium can support nail strength and appearance. While these minerals are present in high amounts, the very high zinc and magnesium dosages raise concerns about long-term safety and suitability for a general nail health regimen.
Impact
Lower effect
Magnesium and calcium are important for heart rhythm and function. Despite their inclusion, the extremely high dosages of both minerals could potentially lead to imbalances rather than consistent support for heart health.
Impact
Lower effect
Magnesium and calcium contribute to cardiovascular well-being. However, the very high doses in this product present potential risks and imbalances that contradict a sensible approach to cardiovascular support.
Impact
Lower effect
Calcium and magnesium are key for muscle function and recovery, relevant for fitness. However, the exceedingly high magnesium and zinc levels could lead to adverse effects, hindering rather than helping athletic performance and recovery.
Impact
Lower effect
Zinc and magnesium are recognized for their roles in brain function. Despite their presence, the excessive dosages, particularly of zinc and magnesium, could potentially cause side effects that detract from cognitive clarity rather than enhance it.
Impact
Lower effect
Magnesium and zinc can play roles in supporting mood. While included, the extreme quantities present a risk of adverse effects that could counteract any potential mood benefits and cause discomfort.
Impact
Lower effect
Magnesium and zinc are involved in energy production pathways. However, the high dosages of these minerals might lead to digestive discomfort or other adverse effects that could ultimately detract from perceived energy levels rather than boost them.
Ingredients
| Ingredient | Amount per serving |
|---|---|
Calcium | 1000 mg |
Magnesium | 400 mg |
Zinc | 25 mg |
Calcium 40
Providing 2000mg of calcium from carbonate and gluconate forms, this product offers a very high amount that, while beneficial for some, is close to the overall tolerable upper intake level when considering dietary calcium. This high dose requires careful consideration to avoid overconsumption.
Magnesium 20
The 800mg magnesium dosage from gluconate and oxide forms is considerably higher than the 350mg upper limit for supplemental magnesium, raising significant safety concerns. This quantity is likely to cause digestive upset and is unsuitable for general daily supplementation.
Zinc 20
The 50mg zinc dosage from citrate and oxide forms exceeds the 40mg upper tolerable intake level for supplemental zinc. This high level can lead to adverse effects, including copper deficiency, and makes the product unsuitable for regular zinc intake.
