## Description

KSM-66 is a patented and full-spectrum extract of Ashwagandha. It is also the most clinically studied Aswagandha, as over two dozen scientific studies back up KSM-66's effectiveness. Research shows that it positively impacts testosterone, strength, quality of sleep, and much more. It is undoubtedly one of the most promising botanical extracts in today's market. We have chosen KSM-66 because it provides a high concentration of Ashwagandha, directly sourced from only the primary roots. The use of roots is superior to that of leaves, as proven by human clinical evidence. Our KSM-66 Aswagandha supplement provides 60 servings, each containing 1000mg of KSM-66.

Review: Gives good and stable energy - I use this in the morning and feel more steady energy through the day. It’s not like caffeine, just a more even feeling.
Review: Pure and potent - I've tried a few different brans, but this version is noticeably high quality. It's been a great addition to my routine for managing daily stress and feeling more centered.

## Features

- WHY YOU SHOULD TRY KSM-66: KSM-66 is widely considered one of the best ashwagandha supplements available. It's a highly standardized extract of ashwagandha, meaning that the levels of withanolides are controlled and consistent in every batch. It's free from contaminants, fillers, and additives, making it a pure and natural source of ashwagandha. KSM-66 has been extensively studied and shown to be safe and well-tolerated.

Our KSM-66 supplement contains a clinical dosage of 1000mg per serving, making it one of the most potent options on desertcart.
- STRESS SUPPORT: Ashwagandha is considered an adaptogen, which means that it may help the body better manage stress.

Several studies have found that taking ashwagandha supplements may help reduce stress.
