For 3 weeks, half received daily fish oil capsules, while the other half got placebo.
How much fish oil? 3.2 g of eicosapentaenoic acid (EPA) and 2.0 g of docohexaenoic acid (DHA).
This dose of fish oil also works in elite athletes with asthma.
The asthma fish oil study showed that the fish oil patients improved pulmonary function.
The study also showed that asthma patients used less bronchodilator.
Asthma is an inflammatory disease and anti-inflammatory fish oil—not flax, walnut or purslane–should help.
Although it is early to know with certainty, the risk seems very small. Look for fish oil free of contaminants.
