Researchers at King’s College London have found that small amounts of DHA, derived from algae, can lower diastolic blood pressure. A lower blood pressure can reduce the risk of cardiovascular disease.
Healthy middle-aged individuals were given docosahexaenoic acid (DHA) or placebo for three months. After a following break for four months, the participants were again given either active capsules or placebo for another three months. The results showed that an intake of 0.7 g DHA lowered the diastolic blood pressure by 3 mmHg.
Previous studies with fish oil have shown that it normally requires at least 2-3 g of EPA and DHA to lower the blood pressure.
