Analysis
Nature's Answer Marine Based Magnesium 500 mg features magnesium sourced from Aquamin Seawater, which contains Magnesium Hydroxide and trace minerals, along with some calcium. This approach offers a natural, broad-spectrum mineral profile.
However, Magnesium Hydroxide, similar to Magnesium Oxide, has relatively poor systemic bioavailability. This means that while it provides a high elemental magnesium content, a significant portion may not be absorbed effectively by the body for cellular functions throughout the body.
Its primary action, therefore, often involves a mild to moderate laxative effect, drawing water into the intestines. It can be a good option for those seeking a natural mineral complex or who also benefit from digestive regularity, but it's not the most efficient for pure systemic magnesium repletion.
Pros
- Sourced from natural marine Aquamin Seawater, including trace minerals.
- Provides a substantial 500mg elemental magnesium per serving.
- Can offer a gentle laxative effect for digestive regularity.
- Capsule form is convenient for daily intake.
Cons
- Magnesium Hydroxide has lower systemic bioavailability compared to chelated forms.
- May cause loose stools or digestive upset in sensitive individuals.
- Not the most efficient choice for maximizing systemic magnesium levels.
Warnings
- May cause loose stools or diarrhea, especially at higher doses.
- Individuals with kidney issues or other medical conditions should consult a healthcare professional.
- If you experience persistent digestive discomfort, consider a more gentle form of magnesium.

Goals
Impact
High effect
Magnesium Hydroxide is effective as a gentle osmotic laxative, drawing water into the intestines to promote digestive regularity. This is a primary benefit of this form.
Impact
High effect
While offering a natural source of magnesium and trace minerals, the lower systemic bioavailability of Magnesium Hydroxide means it's less efficient for general magnesium repletion compared to other forms, but still contributes some benefits.
Impact
High effect
Magnesium is crucial for bone formation, and this product provides a substantial dose, though its bioavailability isn't top-tier for systemic bone repletion. The trace minerals and calcium also contribute.
Impact
High effect
While magnesium is important for heart health, the lower systemic bioavailability of Magnesium Hydroxide means it's less effective at contributing to critical heart functions compared to more absorbable forms. Trace minerals may offer minor indirect benefits.
Impact
High effect
The lower bioavailability of Magnesium Hydroxide means it's less efficient for providing systemic magnesium needed for cardiovascular support. Trace minerals could offer some indirect benefits, but not its core strength.
Impact
Moderate effect
The contribution to anti-aging processes is limited by the lower systemic absorption of Magnesium Hydroxide. While trace minerals are present, it's not a primary choice for targeted anti-aging support.
Impact
Moderate effect
For fitness goals requiring systemic magnesium for muscle function, energy, and recovery, Magnesium Hydroxide is less effective due to its lower absorption rate into the body's tissues.
Impact
Moderate effect
For energy production, magnesium needs to be absorbed and utilized in cells. Magnesium Hydroxide's lower bioavailability makes it a less efficient choice for contributing to systemic energy levels.

Magnesium 70
This magnesium supplement offers a natural, marine-based source (Aquamin Seawater) which provides Magnesium Hydroxide and trace minerals. While a natural option, Magnesium Hydroxide has lower systemic bioavailability compared to chelated forms and is often associated with a mild laxative effect, making it less ideal for pure systemic repletion.
