Well, this is going to be one of our shorter ingredients sections and in reality it’s really just going to be us talking about a few of the studies around Ashwagandha itself and vitamin D.
Ashwagandha has been extensively studied for its anxiety-reducing effects and as we mentioned in the intro, sleep and testosterone production.
Generally speaking sleep and anxiety trials tend to be between 300mg-600mg (as is dosed in golli), with testosterone tending to need to be 600mg to show results. [1,2,3]
The herb itself was successfully shown to reduce cortisol build up (the stress hormone) in multiple human trials. And it's pretty well regarded on this front, with it being the most well benefit claimed by Goli Ashwagandha.
Studies have shown that the effects can take place within 4 weeks, and many users report effects much sooner (however, the clinical trials have generally set their reporting to be after a few weeks, so there isn’t much scientific evidence to support it working faster). [4]
Additionally, it has been shown to improve exercise capacity and energy levels in healthy adults., although a large part of this is as a result of the increased testosterone levels, which is unlikely to mean the same effect for women. [5]
There are some studies that support Goli's claims in regards to sexual health, but these are not nearly as well backed as the stress and sleep studies. [6] And again, most of the evidence relates specifically to men.
Vitamin D2 however, is an odd choice. Vitamin D2, is a less effective form of vitamin D compared to the more commonly used vitamin D3. [7] And of course there are a host of benefits associated with supplementing for vitamin D, particularly in the winter months. [8] Ranging from improved athletic performance, better sleep, reduced cravings, through to basic bodily functions and hormone production. [9]
