The study took place at a health company in Taiwan over a six-month period. Ten male sufferers of androgenetic alopecia aged between 20- and 70- years received a 50mg daily dose of SDG in the form of one 250 mg capsule of Acatris' LinumLife Extra.
The condition of their hair was documented at the beginning of the study by photographs and the men measured their hair loss throughout the period by counting the number of hairs on their pillows each morning.
Initial effects of the flax lignans were noticed on average one to two months into the study, says the company, and the end of the period, eight of the participants reported a modest improvement in their hair loss condition, one reported a great improvement and one reported no effect at all. The more severe the participant's hair loss condition at the start of the trial, the more noticeable the improvement.
Half the subjects also noted decreased oil secretion in their scalp. No adverse effects were reported.
LinumLife EXTRA is a 20% lignan extract from flax. The flax lignan SDG (Secoisolariciresinol diglycoside) is scientifically associated to benefits for prostate, menopause, hair loss, acne and heart health.
Lignans serve in the body to block two critical enzyme systems that serve to initiate prostate cancer and benign prostatic hyperplasia. The first is aromatase, an enzyme that converts testosterone to a powerful testosterone derivative that is five times more powerful than its precursor in promoting prostatic disease. The second is 5-alpha reductase, an enzyme that converts testosterone to estrogen. Despite popular belief, estrogen is much more powerful in provoking prostate disease than testosterone. In fact, the ratio of testosterone to estrogen begins to weigh in favor of estrogen in the aging male. As testosterone levels decline with age, estrogen levels appear to remain relatively stable. Compared to younger men, the ratio of estrogen to testosterone is up to 40 percent higher in older men.
