Liberty BioScience Premium Omega 3 Fish Oil

Our assessment

Our assessment: Liberty BioScience Premium Omega 3 Fish Oil contains calcium, a mineral essential for bone health. The evidence shows that calcium supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, you should be aware that the specific amount of calcium in this product is not listed, so we cannot confirm if it provides a meaningful dose.

How it works

Think of calcium as a structural building block for your bones and a signal regulator for your muscles and nerves. It helps maintain bone density through mineralization and supports proper muscle relaxation and nerve signaling [NIH ODS].

Safety profile

FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from excessive calcium can include constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. You should also know that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

If you are taking any of the medications listed above, consult your doctor before using this supplement. For general bone health, the data does not specify a standard dose for this product. Consider getting your calcium from dietary sources first, and speak with a healthcare provider about whether this fish oil product is right for you.
