These properties can help to normalise hormonal imbalance in women’s health problems associated with too much or too little oestrogen (e.g. premenstrual syndrome and menopause). SDG also shown promising cardiovascular-protective and anti-cancer properties. The latter only in laboratory animal studies, but the former in clinical trials, including those focusing on blood-pressure lowering.
In 2016 a collaborative group of scientists from Australia, Poland and Romania undertook a meta-analysis of human studies on flaxseed supplements for high blood pressure (PMID: 26071633). They searched the world’s medical literature and found 15 clinical trials with a total of 1302 volunteers to include in the analysis.
Pooling all the results showed significant reductions in both systolic and diastolic blood pressure following supplementation with whole flaxseed powder rather than the oil or the purified SDG. There was a greater effect on both these values in trials of more than 12 weeks. Flaxseed is turning out to be a lot more versatile than we thought!
