Coast Science Coast Omega-3 Natural Lemon Flavor

Our assessment

The evidence shows that Coast Science Coast Omega-3 Natural Lemon Flavor contains calcium, a mineral critical for bone health and nerve function. Our assessment: if you are taking this product for its omega-3 content, be aware that you are also getting calcium, which has important benefits and specific risks you need to understand [NIH ODS].

How it works

Think of calcium as a structural builder and a cellular messenger. It supports bone density and mineral deposition for strong bones, and it helps your muscles relax and your nerves signal properly [NIH ODS]. This product provides calcium alongside omega-3s, but the exact amount per serving is not specified in the data provided.

Safety profile

Data not available for this specific product's adverse events. However, the FDA has received a total of 592,059 adverse event reports for all products. For calcium specifically, high intakes from supplements may increase the risk of heart disease and prostate cancer. High 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

We recommend you check the label for the exact amount of calcium per serving. If you take other medications, separate your calcium intake from those doses by at least two hours to avoid absorption issues [NIH ODS]. Do not exceed the recommended daily intake without consulting your doctor, as high calcium carries significant risks [NIH ODS].
