Astragalax is a brand of extract that is meant to help boost weight gain by increasing the absorption of nutrients in the body.
It has been a subject of controversy since it was first identified in a 2009 study published in the New England Journal of Medicine.
The research involved a single woman who gained more than 80kg over three years with a daily dose of 0.5g of the extract.
The study was a placebo, and the authors of the study said the supplement could help with weight gain in overweight people who were overweight and obese.
But a large study has now shown the astraggalus extract can be more effective in reducing body weight than the placebo, according to a report in the British Medical Journal.
Researchers tested the astregalus extract on 647 people between the ages of 19 and 70, and found that it was more effective at increasing body weight in women who were heavier than the average.
The researchers concluded that the astrate extract is likely to be an effective supplement for overweight women, because it has a higher bioavailability than the normal diet and is less likely to interfere with the metabolism of foods.
But the report warned that it could have a major drawback, because the aSTRAGALAX extract can have a negative impact on metabolism and metabolism may decrease over time.
It also noted that the effect of the aStragalac acid on body weight is uncertain, because of its bioavailability.
Astragaleas extract has not been approved by the Food and Drug Administration, but the study has not yet been confirmed by the US Food and Drugs Administration.
