Systolic hypertension is a major risk factor for the onset of strokes and cardiovascular disease. A new double-blinded, randomized controlled trial (1) has shown that a daily dose of fish oil containing 0.7 mg docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) taken for eight weeks was able to reduce systolic blood pressure by a clinically significant 5 mmHg in adults with systolic hypertension.
High blood pressure (hypertension) is largely caused by reduced arterial reactivity and stiffness. Approximately half of adult males and a third of adult females in the United Kingdom have untreated hypertension (i.e., systolic blood pressure of more than 160 mmHg and diastolic blood pressure of more 100 mmHg) and hence are at considerably greater risk of cardiovascular disease.
In the current trial, a daily dose of fish oil containing 0.7 mg DHA and EPA taken for eight weeks was able to reduce systolic blood pressure by a clinically significant 5.2 mmHg in adults with systolic hypertension. This intake level of DHA and EPA can be achieved using two to three portions of oily fish a week or daily consumption of two typical fish oil capsules. The trial took place in the United Kingdom and had 362 participants. The authors commented that a reduction in systolic blood pressure of ca. 5 mmHg would equate to an approximate reduction of 20% of the risk of cardiovascular disease in middle age. The use of a higher dose of 1.8 g of DHA and EPA per day did not produce any further improvements in blood pressure reduction.
This study corroborates a meta-analysis carried out for the Global Organization for EPA and DHA Omega-3s (GOED) last year (2), which found that EPA and DHA lowered blood pressure in adults with hypertension by 4.5 mmHg systolic blood pressure and 3 mmHg diastolic blood pressure.

Marine omega-3 fatty acids are important for the developing brain, adult brain health and protection against cognitive decline in the elderly. DHA is an important structural part of the nervous tissue whilst circulating EPA levels appear to be important in prevention of the onset of depression. This review will examine the current evidence with regard to efficacy.

Close to 75% of hip and non-hip fractures occur among seniors age 65 and older, and by 2050 the worldwide incidence in hip fractures is expected to increase by 240% among women and 310% among men.
