It's certainly hard to ignore the constantly emerging research that suggests the essential fatty acids (EFAs) found in fish oil may play a major role in overall health, including cognitive, joint and heart function. But if you're still on the fence about fish oil, listen up.

A large-scale clinical trial conducted last year found that after taking 850 to 882 mg of omega-3 fish oil per day, individuals previously diagnosed with unhealthy heart function had reduced incidences of mortality and hospital admissions for cardiovascular reasons¹. The researchers suggested that the fish oil may be beneficial to decreasing unhealthy heart rhythms, a potential cause of unhealthy cardiovascular function.

I understand that even after hearing of the many benefits of fish oil, some people may still be weary of the possible unpleasant smell, aftertaste or "fishy burp" generated by some products-I too have experienced this effect.

But it's important to remember that not all fish oil products are the same. There are many easy-to-take forms available that can reduce or eliminate unpleasant effects, from pudding-like gels and chewable gummies to pleasantly flavored liquids and softgels. Look for a top-quality formula that delivers optimal levels of EFAs and is molecularly distilled to ensure that harmful heavy metals and toxins have been removed. I personally recommend at least 800 mg of EPA and 400 mg of DHA per day to help promote healthy cardiovascular function, joint mobility and mood support.

This may come as no surprise, but I consider fish oil to be one of the most important supplements that can be consumed (along with vitamin D and multi-vitamins), and recommend that it be taken by absolutely everyone, regardless of age, gender or health.
