It is well-known that omega-3 fatty acids can improve long-term heart health.
A study published in the medical journal Chest indicates that omega-3 fatty acids contained in fish oil may improve heart function even after short-term supplementation.
Researchers followed 58 people aged 60 or older who were randomly assigned to take either marine-derived omega-3s (fish oil) or plant-derived omega-3s (alpha-linolenic acid) from soy oil.
The oils were taken as 1-gram capsules, twice daily for six months.
A measure of heart-healthiness called heart rate variability (HRV) was assessed every other day.
Supplementation with 2 grams a day of fish oil was associated with a significant increase in HRV. The supplementation with 2 grams a day of soy oil also significantly improved HRV, but to a lesser degree than the fish oil.
In addition to other factors known to improve heart health, such as exercise, weight loss, and stress reduction, taking a daily omega-3 oil supplement may therefore reduce the risk of developing irregular heart rhythm or succumbing to sudden cardiac death.

Note from Deanna Waters: My husband and I appreciate the science behind the USANA BiOmega fish oil supplements, which contain a concentrated dose of two important Omega-3 fatty acids - EPA and DHA - to support healthy cellular function throughout the body.
