Sensoril® Ashwagandha – ingredient guide | Skytrition
What is Sensoril® really, and what sets it apart from a dietary supplement that just states “ashwagandha”? To understand a plant-based ingredient, we need to look at more than just the name: plant parts, extraction method, standardization, and amount per serving all play a role.
In this ingredient guide, we go through Sensoril® Ashwagandha and how to read the information about the extract. Towards the end, you will also find the verified amounts in Skytrition's RestUP and EaseUP.
What is Sensoril® Ashwagandha?
Sensoril® is a branded, standardized extract of ashwagandha, Withania somnifera. In the published STAR study, it is described as a water extract produced from the plant's roots and leaves.
Ashwagandha is thus the plant, while Sensoril® identifies a specific extract. It is not the same thing as regular ground plant powder, and research on a different ashwagandha extract cannot automatically be used to describe Sensoril®.
Root, leaf, and extraction: why does it matter?
Different plant parts can have different compositions. Furthermore, the extraction method affects which substances end up in the finished extract. Therefore, it is not enough that two products come from the same plant for them to be directly comparable.
That Sensoril® is described as a water extract indicates how the raw material has been extracted. This is a detail about the production, not in itself proof of better absorption or greater effect. Such comparisons require separate documentation.
What does standardization mean?
Standardization means that an extract has a specified content of certain substances. Withanolides are a group of substances found in ashwagandha. On EaseUP's ingredient label, Sensoril® is stated as standardized to 10 percent withanolides.
The percentage describes the extract's composition. It should not be interpreted as the product having “10 percent effect,” and it does not alone say how a dietary supplement will be experienced.
Milligrams and percentages are different pieces of information
EaseUP contains 125 mg of Sensoril® per 2 capsules. With the stated standardization of 10 percent, this mathematically corresponds to 12.5 mg of withanolides. At 4 capsules, 250 mg of extract is stated, which corresponds to 25 mg according to the same calculation.
This is a calculation from the label, not an independent laboratory analysis or dosage recommendation. Always compare the actual serving size. We do not use EaseUP's percentage figure to calculate for RestUP, because the same standardization is not explicitly stated in the controlled ingredient table for RestUP.
What can research tell us about Sensoril®?
An ingredient guide should distinguish between studies on Sensoril®, studies on other ashwagandha extracts, and studies on finished products. They are not interchangeable.
A concrete example is the STAR study, published in 2018 in Nutrients. It examined Sensoril® in connection with a structured strength training program. The study was randomized, double-blind, and placebo-controlled, with 19 men in each group. The Sensoril group received 500 mg daily for 12 weeks. The researchers examined, among other things, strength, body composition, and recovery metrics.
How such a study should be interpreted
The setup provides a concrete example of how the extract has been investigated, but it has clear limitations. The participants were exercise-active men, the groups were small, and both groups followed a training program. The study was funded by Natreon, Inc., which is relevant to know when assessing the evidence base.
It cannot be used as a general dosage instruction, as proof of long-term safety, or as documentation for all target groups. The study did not test RestUP or EaseUP. Nor does it in itself show what these finished products do for sleep or stress.
We therefore do not use the study to promise a certain effect. For a fair research assessment, one needs to weigh together several relevant studies, their quality, funding, participants, and consistency, not just pick one single positive result.
How to compare Sensoril® with other ashwagandha extracts?
Start with the raw material: which extract is stated, which plant parts are used, and what standardization is declared? Then look at the amount per recommended serving, not just the number of milligrams on the front of the packaging.
Comparisons also require that percentage figures refer to comparable substances and analysis methods. A higher milligram figure or a higher percentage is not alone a sufficient reason to call an extract better.
Finally, you need to read the entire formula. Other ingredients, overlap with your other dietary supplements, and the instructions for use can be just as important as which ashwagandha raw material is included.
Sensoril® in Skytrition's products
RestUP: a formula for the evening routine
RestUP – Night Time Formula contains 125 mg of Sensoril® per 3 capsules and 250 mg per 6 capsules. The extract is included there together with, among other things, EZGABA®, green tea extract with L-theanine, chamomile extract, Vanizem®, magnesium bisglycinate, zinc bisglycinate, and Affron® saffron extract.
RestUP is, according to the product information, intended to be taken before bedtime. Read the current ingredient list and dosage instructions on the product page and packaging.
EaseUP: a different composition
EaseUP contains 125 mg of Sensoril® per 2 capsules and 250 mg per 4 capsules, standardized to 10 percent withanolides according to the ingredient list. The formula also contains NeuroFlow™ phosphatidylserine, green tea extract with L-theanine, and SalidroPure® salidroside.
EaseUP is developed for an active everyday life, with recommended dosage after physical activity according to the dosage section. The difference from RestUP lies in both the amount of Sensoril®, other ingredients, and the usage routine.
Important about use and overlapping ingredients
RestUP and EaseUP both contain Sensoril® and L-theanine from green tea extract. That the products have different usage routines does not automatically mean that they should be combined. Take into account the total intake of shared ingredients and do not assume that the respective maximum dose is also an appropriate combined dose.
The products are intended for healthy people over 18 years of age. If you are pregnant, breastfeeding, have an illness, or are treated with medication, you should contact a doctor before use. Always follow the current labeling and do not exceed the recommended daily dose.
Short studies in a limited target group cannot guarantee safe use for everyone or over a long time. Discontinue use and contact medical care if you get symptoms that you suspect are linked to a dietary supplement.
Dietary supplements do not replace a varied and balanced diet or a healthy lifestyle. Keep the products out of reach of small children.
Frequently asked questions about Sensoril®
Is Sensoril® the same thing as regular ashwagandha powder?
No. Sensoril® is a specific standardized extract, while a plant powder is not the same type of preparation. The milligram amounts can therefore not be compared directly.
Is Sensoril® a pure root extract?
The published STAR study describes Sensoril® as a water extract from both roots and leaves of Withania somnifera.
What does 10 percent withanolides mean?
It is a detail about the extract's declared composition. In EaseUP, this standardization is explicitly stated. The percentage is not a measure of a guaranteed effect.
How quickly does one notice a difference?
It is not possible to specify a reliable time based on the ingredient list or the study described here. A study's duration is not the same thing as a guaranteed time to perceived effect. We therefore do not promise a certain result after a certain number of days.
Is the higher dose always the better choice?
No. Base it on the product's instructions and your situation, not on the assumption that more is always better. A study dose is not automatically a recommended dose for you.
Summary
Sensoril® is a standardized ashwagandha extract which, in published research, is described as being produced with water from root and leaf. To understand the ingredient, you need to read the extract name, standardization, serving size, and research evidence together.
At Skytrition, Sensoril® is available in RestUP and EaseUP. The products have different compositions. Read the entire product information and follow the current labeling before use.
