Crystal Star Ocean Minerals
Brand: Crystal Star · Form: CAPSULE [E0159] On Market
Our assessment
Our assessment: Crystal Star Ocean Minerals provides calcium, which is essential for bone health. The evidence shows that calcium supports bone mineralization and neuromuscular function [NIH ODS]. However, we must be clear that data on the specific "Ocean Minerals" formulation is not available beyond its calcium content.
How it works
Think of calcium as a structural building block for your bones and a key signaler for your nerves and muscles. It supports bone density and mineral deposition, and it helps your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements, but specific report counts for this product are not available. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High blood calcium levels can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: If you are using this for calcium, be aware that total calcium intake from all sources (food and supplements) should be monitored. Avoid exceeding 2,000–2,500 mg daily from all sources combined, as high intakes carry significant risks [NIH ODS]. Because specific data on this product's safety and efficacy is limited, we recommend consulting your healthcare provider before use, especially if you take any of the medications listed above.
