Black seed oil may support healthy blood pressure, says recent study

May 6, 2020

A study recently published in Food Science & Nutrition Research1 found that supplementation with a standardized black seed oil (ThymoQuin from TriNutra; Harrison, NY) supported blood pressure in healthy subjects. In the study, 20 subjects with normal blood pressure were all treated with a daily doses of black seed oil for six weeks. Following a three-week washout period, patients were given a placebo treatment for another six weeks. Subjects had their blood pressure tested daily throughout the study.

Results showed that following the six weeks of supplementation with the black seed oil decreased systolic blood pressure by 11.2% and diastolic blood pressure by 12.2%. An initial significant decline in blood pressure was observed in as little as two days. Following six weeks of placebo, subjects’ blood pressure elevated slightly.

“Almost a third of the adult population in America experience hypertension, and natural products, including Nigella sativa oil, have long been considered as a therapeutic remedy in many traditional medicine practices across the world,” said Morris Zelkha, CEO of TriNutra, in a press release. “This study demonstrated how ThymoQuin can help provide significant improvement towards healthy blood circulation measurements, which has not been seen from other more common varieties of black seed oil.”

ThymoQuin’s exclusive North America distributor is Barrington Nutritionals.
