Cal/Mag Zinc
NaturesPlus
Score 20
This supplement uses highly bioavailable amino acid chelate forms for calcium, magnesium, and zinc, but the magnesium (500mg) and especially zinc (75mg) dosages are excessively high, with zinc exceeding safe limits, posing significant health risks for regular use.

Analysis
NaturesPlus Cal/Mag Zinc supplement delivers these three essential minerals in amino acid chelate forms, which are generally well-regarded for their absorption. It includes 1000mg of calcium, 500mg of magnesium, and 75mg of zinc. This chelated approach aims to enhance mineral uptake and utilization in the body, supporting functions like bone health, muscle contraction, and immune response.
However, the significant concern with this formulation is the exceedingly high dosages of magnesium and, particularly, zinc. The 500mg of magnesium per serving far exceeds the 350mg upper limit for supplemental magnesium, making digestive upset very likely. Even more problematic is the 75mg of zinc, which is well over the 40mg upper tolerable intake level for adults, risking adverse effects such as copper deficiency and immune dysfunction with regular use. The 1000mg of calcium is reasonable but part of an overall unbalanced blend.
While the choice of amino acid chelate forms is excellent for bioavailability, the extreme quantities of magnesium and zinc render this product impractical and potentially unsafe for general daily supplementation. Users seeking balanced mineral support would find these dosages difficult to manage without risking overconsumption and its associated health problems.
Pros
- Uses amino acid chelate forms for all three minerals, which are generally recognized for superior bioavailability and absorption.
- Provides a substantial dose of calcium (1000mg) from a well-absorbed form.
- Good ingredient transparency by clearly stating the chelated forms.
- From NaturesPlus, a brand often focused on quality formulations.
Cons
- Zinc dosage (75mg) is dangerously high and significantly exceeds the 40mg upper tolerable intake level for supplemental zinc, risking adverse effects like copper deficiency.
- Magnesium dosage (500mg) is also significantly above the 350mg upper limit for supplemental magnesium, highly likely to cause digestive upset.
- Excessive zinc intake can lead to immune system dysfunction and metallic taste.
- High magnesium intake can cause severe digestive issues like diarrhea and abdominal cramps.
- The overall mineral balance is severely compromised by the excessively high magnesium and zinc.
Warnings
- Consult a healthcare professional before taking this product due to the extremely high dosages of magnesium and zinc.
- Excessive zinc intake (75mg) can cause copper deficiency, nausea, and impaired immune function.
- High doses of magnesium (500mg) are highly likely to cause severe digestive disturbances such as diarrhea and cramping.
- Individuals with kidney disease or other medical conditions should strictly avoid high mineral supplementation without direct medical guidance.

Goals
Impact
Lower effect
Calcium and magnesium are crucial for bone health, and this product provides both in bioavailable forms. However, the excessively high magnesium dosage could lead to digestive issues and mineral imbalances, making it a risky choice for consistent bone support.
Impact
Situational effect
Zinc and calcium contribute to nail strength. Despite the excellent forms, the dangerously high zinc (75mg) and high magnesium (500mg) dosages present a risk of adverse effects, making it unsuitable for a safe and consistent nail health regimen.
Impact
Situational effect
Magnesium and calcium are important for heart function. Despite their inclusion in good forms, the extremely high dosages of both magnesium and zinc can lead to imbalances and severe adverse effects, contradicting a safe and beneficial approach to heart health support.
Impact
Situational effect
Magnesium and calcium are involved in cardiovascular health. The product provides these, but the dangerously high magnesium and zinc doses present significant risks and potential imbalances, making it unsuitable for cardiovascular support.
Impact
Situational effect
Calcium and magnesium are vital for muscle function and recovery, important for fitness. However, the dangerously high magnesium and zinc dosages could lead to severe digestive issues and other adverse effects, hindering rather than helping athletic performance and recovery.
Impact
Situational effect
Zinc and magnesium are linked to brain function. Despite the good chelated forms, the dangerously high dosages could cause severe side effects that detract from cognitive clarity rather than enhance it, making it an impractical choice.
Impact
Situational effect
Magnesium and zinc can play roles in supporting mood. While included, the dangerously high magnesium and zinc quantities present a risk of severe adverse effects that could counteract any potential mood benefits and cause significant physical and mental discomfort.
Impact
Situational effect
Magnesium and zinc play roles in energy production pathways. However, the dangerously high magnesium and zinc dosages might lead to severe digestive discomfort and other adverse effects that could ultimately detract from perceived energy levels rather than boost them.
Ingredients
| Ingredient | Amount per serving |
|---|---|
Calcium | 1000 mg |
Magnesium | 500 mg |
Zinc | 75 mg |
Calcium 60
The product provides 1000mg of calcium from amino acid chelate, which is a generally well-absorbed form. This amount is a good contribution to daily calcium needs for many individuals, assuming they don't consume excessive calcium from other sources.
Magnesium 30
The 500mg magnesium from amino acid chelate, while a good form, significantly exceeds the supplemental upper limit of 350mg. This high quantity is highly likely to cause severe digestive upset and is unsuitable for optimal daily supplementation.
Zinc 15
The 75mg zinc from amino acid chelate, while a good form for absorption, is dangerously high and far exceeds the 40mg upper tolerable intake level for supplemental zinc. This extreme dose carries a significant risk of adverse effects, including copper deficiency.
