Barlean's Master Blend Total Omega 3-6-9 Lemonade Flavor

Our assessment

The evidence shows that Barlean's Master Blend Total Omega 3-6-9 Lemonade Flavor provides a source of essential fatty acids, but you should be aware that its key ingredient according to our data is calcium. Our assessment is that while omega fatty acids are important, the calcium content in this specific product may be significant for your daily intake. Data on the exact dosage of omega-3, -6, and -9 in this product is not available.

How it works

Calcium works in your body primarily through bone mineralization, helping to build and maintain strong bones by supporting bone density and mineral deposition [NIH ODS]. It also plays a role in neuromuscular relaxation, supporting proper muscle relaxation and nerve signaling throughout your body [NIH ODS]. The omega fatty acids in this blend contribute to general cell membrane health, though specific mechanisms for this product's blend are not detailed in our data.

Safety profile

The FDA has received a total of 592,059 adverse event reports across all dietary supplements, though specific reports for this product are not available. For calcium specifically, high intakes can lead to constipation, nausea, and abnormal heart rhythms [NIH ODS]. You should be cautious: high levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, extreme tiredness, and a high risk of death from heart disease [NIH ODS]. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].

Our recommendation

We recommend you check your total calcium intake from all sources before adding this supplement, as calcium can reduce the absorption of medications like tetracycline antibiotics, levothyroxine, and phenytoin [NIH ODS]. If you are taking any of these medications, take this product at least two hours apart. For most adults, confirm with your healthcare provider whether you need additional omega fatty acids and calcium, as data on the specific omega content in this product is not available.
