Panax Ginsing & Testosterone
Asian Panax Ginseng has been found to have positive benefits on mood, immunity, and brain function.
As per its effects on testosterone, let’s take a quick look at the research:
- 60 patients with low-moderate ED were given either 3g of Korean Red Ginseng (KRG) daily or placebo. After 12 weeks, the subjects receiving KRG reported stronger erections, but T-levels remained unchanged (1).
- Men with poor sperm mobility supplementing with panax ginseng were found to have improved markers of androgenic hormones (2).
Although the effect on testosterone seems negligible, Panax Ginseng does seem to be a potent nitric oxide booster (3),
i.e. it dilates the blood vessels and improves blood flow.
