Fish oil has been heavily researched over the last few decades.
The research has found that fish oil has a number of potential benefits, including reducing inflammation and incidences of cardiovascular diseases, such as high blood pressure or strokes, as well as helping to alleviate anxiety (pages 128-131).
Reduction in Blood Pressure
There are two types of blood pressure: systolic and diastolic. An average blood pressure reading is 120/80, where systolic is the first number, and diastolic is the second.
Systolic pressure estimates how much pressure is pushed through the artery walls when the heart beats.
Diastolic pressure indicates how much pressure is pushed through the artery walls while the heart is at rest.
Fish oil supplementation has been shown to help people reduce blood pressure slightly over an extended period of use.
Here are two studies that showed a decrease in blood pressure:
We can trust that fish oil is applicable for reducing blood pressure, to a slight degree. As blood pressure is reduced, the incidence of a heart attack or stroke is also reduced.
As we participate in exercise or sports activities, an increase in inflammation is a universal side effect that applies to everyone. As we start to age, tendinitis, arthritis, bursitis, or pain is a chronic side effect that naturally occurs.
Fish oil has been shown to reduce these possible side effects of inflammation. A daily dosage of 3-6 grams (total of EPA and DPA) for 22 weeks resulted in decreased joint tenderness and stiffness in the morning (page 130).
Reductions in Anxiety
Research has demonstrated that fish oil can help to reduce anxiety. This study was for medical students. They did a pre and post self-report test that measured anxiety called the Beck Anxiety Inventory. A dosage of 2.5 grams of omega-3 was able to reduce anxiety by 20%.
NSG Heart Health is a combination of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DPA). To minimize the "fish burp" aftertaste, take fish oil with meals.
