Traditional Chinese Medicine Danggui Buxue Tang May Reduce Running Times, Boost Iron
Exercise can increase levels of hepcidin (the hormone responsible for iron levels), which leads to less iron transport and lower iron levels. A recent study suggests that a traditional Chinese medicine combination of Astragalus membranaceus and Angelica sinensis called Danggui Buxue Tang may reduce running times and boost iron levels during recovery in active men.
Participants in the study included 36 recreationally active men who were given either 5 grams of Danggui Buxue Tang or a placebo daily for 11 days. On day eight of supplementation, all of the men ran 13 km with maximal effort.
The researchers found that finish times in the Danggui Buxue Tang group were shortened by 14% (12 minutes) when compared with the placebo. They also found that the Danggui Buxue Tang group had lower hepcidin levels and corresponding increases in iron levels of 63% immediately after exercise and 31% after 72 hours of recovery.
The Danggui Buxue Tang group also had significantly lower levels of malodialdehyde, a marker of oxidative stress, 72 hours after exercise, when compared with the placebo.
Researchers from Kaohsiung Medical University in Taiwan conducted the study. It was published on September 18, 2018, in Nutrients.
