07 May 2020 --- Israeli company Trinutra’s cold-pressed black seed (Nigella sativa) oil can have a positive impact on blood pressure and heart rate levels. This is according to a new Trinutra-endorsed study, published in the journal Food Science & Nutrition Research. The seeds contain a high amount of thymoquinone which is the main active ingredient and a powerful antioxidant – hence the product’s name, ThymoQuin 3%. The non-randomized human clinical study tested the effects of ThymoQuin 3% in combination with a free fatty acid level of 1.8 percent on blood pressure and heart rate in healthy individuals.
