Shoden is a concentrated ashwagandha extract standardized to contain 35% withanolide glycosides, the primary active compounds in the plant. That’s a significant jump from most commercial ashwagandha extracts, which typically contain between 2.5% and 10% withanolides. The higher concentration means you need a much smaller dose to get measurable effects, usually just 120 mg per day compared to the 300 to 600 mg common with other extracts.
How Shoden Differs From Standard Extracts
Ashwagandha supplements vary enormously depending on how the plant material is processed and what the final extract is standardized to contain. Shoden, developed by Arjuna Natural Pvt. Ltd., uses both the root and leaf of the ashwagandha plant to achieve its 35% withanolide glycoside concentration. Most other popular extracts on the market are standardized to far lower percentages, and the practical difference is substantial.
A pharmacokinetic study published in Heliyon compared Shoden (labeled WS-35 in the research) head-to-head against a 2.5% withanolide extract. After normalizing the doses so both groups received the same total amount of withanolides, Shoden’s active compounds stayed in the bloodstream dramatically longer. The half-life was 5.18 times higher, peak blood concentration was 5.62 times higher, and total absorption over time was roughly 280 times greater per milligram of extract consumed. In plain terms, the withanolides in Shoden are absorbed far more efficiently and cleared from the body much more slowly than those in lower-concentration extracts.
This is why Shoden’s effective dose is so small. Where a standard root extract might require 600 mg daily, Shoden clinical trials have used 60 to 120 mg per day and still produced significant results.
Effects on Stress and Cortisol
A randomized, double-blind, placebo-controlled trial tested Shoden at two doses (60 mg and 120 mg daily) in physically healthy adults experiencing high stress levels. Both doses significantly reduced morning serum cortisol, the hormone your body releases in response to stress. Both doses also increased total testosterone levels. These changes matter because chronically elevated cortisol is linked to sleep disruption, weight gain (particularly around the midsection), and impaired immune function. Lowering it to a healthier baseline can improve energy, mood, and overall resilience to daily stress.
Effects on Sleep Quality
Sleep is one of the best-studied applications of Shoden specifically. In a trial of 150 healthy adults who scored high on measures of non-restorative sleep, participants took 120 mg of Shoden daily for six weeks. The results were striking: the treatment group reported a 72% improvement in self-reported sleep quality, compared to 29% in the placebo group.
Objective data from activity monitors backed up the subjective reports. Compared to placebo, the Shoden group showed significant improvements across every major sleep metric: total sleep time, how quickly they fell asleep (sleep latency), how often they woke during the night, and overall sleep efficiency. Quality-of-life scores also improved significantly in the physical, psychological, and environmental domains. This study is notable because the participants weren’t insomniacs. They were otherwise healthy people who simply weren’t sleeping well, which describes a large portion of the population.
Typical Dosage
Clinical trials have used Shoden at 60 mg and 120 mg per day, with 120 mg being the more common dose in published research. The NIH notes that one study used capsules containing 21 mg of withanolide glycosides per 60 mg capsule, with participants taking two capsules daily for a total of 120 mg of extract (delivering about 42 mg of withanolide glycosides).
For context, studies on other ashwagandha preparations have used anywhere from 240 to 1,250 mg per day of extract, or up to 12,000 mg of whole root granules (equivalent to about 6,000 mg of root powder). Shoden’s effective dose is a fraction of these amounts because of its higher withanolide concentration and superior absorption. Most supplement brands offering Shoden sell it in 120 mg capsules taken once daily.
Safety and Side Effects
Ashwagandha in general, including Shoden, may cause drowsiness, stomach upset, diarrhea, or vomiting in some people. There have also been rare but documented cases of liver injury linked to ashwagandha supplements, though these reports don’t distinguish between extract types. Short-term use (up to three months) appears safe for most adults, but there isn’t enough data to draw firm conclusions about long-term safety.
Several groups should avoid ashwagandha entirely. It should not be used during pregnancy or while breastfeeding. People with autoimmune conditions, thyroid disorders, or hormone-sensitive prostate cancer should also steer clear, since ashwagandha can influence immune function, thyroid hormone levels, and testosterone. If you take medications for diabetes, high blood pressure, seizures, or thyroid conditions, or if you use sedatives or immunosuppressants, ashwagandha may interact with those drugs. The drowsiness effect is worth keeping in mind if you’re already taking anything sedating, though for people using Shoden specifically to improve sleep, that drowsiness may actually be welcome.
