What percent withanolides does this product contain?

The active ingredient in ashwagandha is a group of flavonoids called withanolides, which help support the body's ability to manage stress symptoms and promote relaxation. At this strength the breakdown is something like this:The steroidal lactones Withanone (Dry weight of the roots at 5.54+/-0.4mg/g and 18.42+/-0.8mg/g leaves14), 27-deoxywithanone (1.63+/-0.2mg/g in the leaves and 3.94+/-0.4mg/g in the roots14), and 27-hydroxywithanone (0.50+/-0.1mg/g dry weight leaf and root14)The 5,6-epoxy steroidal lactones Withaferin A15 (22.31+/-1mg/g dry weight of leaves and 0.92+/-0.4mg/g in roots14) and 17-hydroxy-27-deoxy-Withaferin A (3.61+/-0.5mg/g dry weight of leaf and 0.66+/-0.2mg/g root14)The Withanolide series of 6,7-epoxy steroidal lactones mostly looking at Withanolide A15 (root at 3.88+/-0.7mg/g, leaf at 2.11+/-0.5mg/g14) but also B-D;16 there are some variants such as 27-hydroxy Withanolide B (0.55+/-0.2mg/g root and 2.78+/-0.5mg/g dry leaf weight14)The Withanoside series of steroidal lactones, usually Withanoside IV (0.44+/-0.1mg/g in the root dry weight and 1.60+/-0.2 in the leaves14) and VI (1.90+/-0.2mg/g in the leaves and 3.74+/-0.2mg/g in the roots14) although up to 19 exist16Diepoxy variants of the withanolides such as 5β,6β,14α,15α-diepoxy-4β,27-dihydroxy-1-oxowitha-2,24-dienolide17Chloronated withanolide variants such as 27-acetoxy-4β,6α-dihydroxy-5β-chloro-1-oxowitha-2,24-dienolide1718 and Withanolide Z19Withanolide glycosides, which are referred to as Sitoindosides (or glycowithanolides)202112-deoxywithastromonolide at 2.15+/-0.5mg/g in the leaves and 1.90+/-0.5mg/g in the roots14Physagulin (3.46 ± 0.4mg/g in the leaves; not detectable in the root14) with variants (4,16-dihydroxy-5β,6β-epoxyphysagulin D22) and glycosides (27-O-β-d-glucopyranosylphysagulin D22)Ashwagandhanolide (Withaferin A dimer bound by a sulfur bridge which breaks the epoxide site, or 'thiowithanolide'),2324 the same molecule but with a sulfoxide rather than a sulfur bridge (Withanolide sulfoxide),24Viscosa lactone B16Other sulfated steroidal lactones25Kaempferol at 0.06mg/g (fruit dry weight, none in roots nor leaves)26Naringenin at 0.50mg/g in the fruit by dry weight (none in roots nore leaves)26(+)-Catechin at 12.82mg/g (roots), 19.48mg/g (fruits), and 28.38mg/g dry weight (leaves)26Gallic acid at 0.18mg/g dry weight of the leaves (none in root nor fruit)26Phenolic acids such as Syringic acid (0.30mg/g in the leaves), p-coumaric acid (0.80mg/g in the leaves), vanillic acid (0.15mg/g leaf dry weight), and benzoic acid (0.80mg/g in the leaves)26A 1,4-dioxane derivative (2,5-Dioxo-3-tetratriacont-3′-enyl-1,4-dioxane)27β-sitosterol and stigmaterol, as well as each molecule's glucoside.2814Trigonelline (1.33+/-0.3mg/g in the leaves14)Palmitic acid in the leaves (3.55+/-0.5mg/g dry weight14) and root (1.18+/-0.2mg/g dry weight14)Oleic acid in the leaves (0.71+/-0.1mg/g dry weight14) and root (0.39+/-0.1mg/g dry weight14)Linoleic acid in the leaves (1.52+/-0.2mg/g dry weight14) and roots (1.31+/-0.2mg/g dry weight14)Linolenic acid in the leaves (4.38+/-0.5mg/g dry weight14) and roots (0.15+/-0.1mg/g dry weight14)

Does this extract compare favorably with ksm-66 or sensoril?

Sensoril uses extracts from both the leaf and roots of the ashwagandha herb, KSM-66 is only the root extract so is higher concentration full spectrum.I found the Ashwagandha Extract 500 mg which is an adaptogen (gives the body what is needs) to be very efficient. I accidentally took an extra pill and found that it felt like I had one too many drinks...coordination was off and I was woozy. So this strength in one pill does fine.

How big are the capsules?

They're medium sized. Not so large that they're hard to swallow

what amount of active ingredient (root extract) - 'withanolides' does this product contain?

The label information is not listed in percentages. However the only other ingredients are vegetable cellulose (capsule), silica, vegetable magnesium stearate. I believe they are a very small percentage of the total considering ingredients are generally listed in order of quantity.
