Each serving of Alpha JYM provides 500 mg of ashwagandha root concentrated at a 5:1 extract. With two servings per day, that's 1000 mg (1 gram) of concentrated ashwagandha. That's equivalent to 5000 mg (5 grams) of pure ashwagandha root powder, which is the amount provided in the research suggesting positive benefits on testosterone levels.
Known scientifically as Withania somnifera, ashwagandha has been used in ancient Indian Ayurveda and Unani for many centuries. This shrub plant is well known for its adaptogenic effects, which means that it helps the body better deal with stress, such as from exercise.*
Research suggests that ashwagandha may also work to naturally optimize testosterone levels.* Indian researchers reported that males with normal testosterone levels supplementing with ashwagandha for three months experienced an increase in their testosterone levels at the end of the study.*
Other research suggests that ashwagandha supplementation may lead to an increase in testosterone with a concomitant decrease in cortisol. The main way ashwagandha affects testosterone levels is by helping to preserve the activity of key enzymes involved in testosterone production.
Here's more interesting information: A 2016 study published by Indian researchers suggested that supplementing with Ashwagandha may support weight loss in overweight elderly and middle-aged people reporting high stress in their life. (And really, who doesn’t have a lot of stress in their lives?)
The researchers gave subjects 300 mg of Ashwagandha twice a day for eight weeks. They reported that the group supplementing with Ashwagandha experienced more weight loss than those getting a placebo. The greater weight loss was attributed to fewer food cravings and an ability to maintain better eating habits (less emotional eating, etc.) than those taking the placebo.
Reducing stress may not only have a big impact on your eating habits and potentially weight loss, but may also help your strength and muscle mass gains.* Research suggests that subjects reporting higher stress levels gain far less strength and muscle mass on a weight-lifting program compared to those reporting low stress.
