Our assessment
The evidence shows that this product contains 400 mg of magnesium per serving, which is a significant dose. For most adults, the RDA for magnesium ranges from 310 to 420 mg daily [NIH ODS]. The data provided does not include any specific health claims or supporting studies for this exact product, so our assessment is based on general mineral knowledge only.
How it works
Magnesium supports over 300 biochemical reactions in your body. It plays a role in muscle and nerve function, blood glucose control, and protein synthesis. However, the specific mechanism for this California Natural product is not detailed in the data provided. For comparison, calcium, a related mineral, supports bone mineralization and neuromuscular relaxation [NIH ODS].
Safety profile
Data not available for this specific product’s side effects. Overall, the FDA has received 592,059 total adverse event reports across all supplements, but no report count is linked to magnesium or this brand [FDA data]. High doses of calcium can cause constipation, nausea, and abnormal heart rhythms, but these data are not specific to magnesium [NIH ODS].
Our recommendation
Start with a lower dose if you are new to magnesium supplements. Because the data provided lacks studies, specific benefits, and side effect reports for this product, we cannot endorse it for any particular health outcome. Always consult your doctor before starting a new supplement, especially if you take medications such as bisphosphonates or antibiotics, as minerals can reduce absorption [NIH ODS].
