Nordic Naturals Ultimate Omega Lemon

Our assessment

For a general health supplement like Nordic Naturals Ultimate Omega Lemon, the evidence for omega-3 fatty acids is strong, but the data we have is specifically about calcium. Our assessment is that this product’s value depends entirely on its omega-3 content, which is not detailed in the data provided. We cannot verify the specific benefits or risks of this exact product based on the available information.

How it works

While we cannot speak to the mechanism of the specific fish oil in this product, the ingredient data we have is for calcium. Calcium works as a master regulator for bone mineralization, supporting bone density and mineral deposition. It also supports neuromuscular relaxation by aiding muscle relaxation and nerve signaling [NIH ODS].

Safety profile

Data not available for this specific product. The FDA has received a total of 592,059 adverse event reports across all dietary supplements, but we cannot attribute any to Nordic Naturals Ultimate Omega Lemon [FDA data]. For the ingredient calcium, high intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS].

Our recommendation

Because the data provided does not include any specifics on the omega-3 content, dosage, or clinical studies for this product, we cannot make a confident recommendation. For any supplement, consult your healthcare provider to ensure it is appropriate for your individual health needs and does not interact with your medications. Remember that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
