Those are the themes that recur across the reviews. Low review confidence — Amazon’s 3.8 from 122 ratings differs from the 4.46 on the brand’s own widget, where 36% of reviews are not flagged as verified buyers, there is no Trustpilot presence beyond two brand-wide reviews, and the Amazon listing’s description is text copied from another product.
Why it might work
The brand describes constipation as slow gut muscle movement and builds the product around three signals: bile (artichoke is said to raise bile acid secretion, which the brand links to faster stomach emptying and bowel movement), the gut lining (okra’s mucilage) and stress or serotonin timing (ashwagandha). In the maker’s trials, the blend lowered blood cortisol and raised serotonin and gastrin while symptom scores fell, which the authors read as a gut-brain effect; those blood markers do not by themselves show that the gut moves faster, though the larger trial also reports shorter transit time. The artichoke mechanism comes from the brand and ingredient literature on bile, not from a measurement in the dyspepsia trial. Neither ashwagandha nor artichoke is a fiber, osmotic agent or stimulant. The label does not let a reader check the extract strengths or the herb ratio.
What the research supports
No trial of Motility itself was found. Its main active, Digexin (500 mg of ashwagandha root and okra fruit extracts), has two placebo-controlled trials in functional constipation at 300 or 500 mg a day, 48 people for 14 days and 135 people for 60 days, both reporting significant gains in constipation symptom and quality-of-life scores; the 135-person trial was funded by the ingredient’s marketer and no independent replication was found. The artichoke leaf extract has a 247-person trial in functional dyspepsia at 1,920 mg a day, about five times the 400 mg here, and no trial in constipation was found. The label’s 500 mg Digexin matches the trial dose at one serving, while the four-capsule tier doubles it.
What the label discloses
Each active has its own amount (Digexin 500 mg, artichoke leaf extract 400 mg with more than 5% flavonoids per two capsules), but the label does not give the ashwagandha-to-okra split or name the artichoke extract. There is no allergen or free-from statement, and the label has no ashwagandha or artichoke warning. The brand states third-party-tested ingredients in general and names no laboratory for this product.
Who this tends to suit
We match this product to people reporting constipation, irregular bowel habits and bloating. It fits someone whose priority is regularity or day-to-day comfort. Whether it is the best fit for you depends on the rest of your answers — what you have already tried, what format you will take, and anything that has to be ruled out.
Where it may not fit
The label supports no added sweeteners. We flag this product for anyone pregnant or breastfeeding or taking prescription medication, and the quiz removes it rather than recommending it in those cases. That is a caution about who should be deciding, not a claim about the product. A capsule only works if you will take it once a day, every day.
Side effects and what to be aware of
About one in six of the 284 reviews on the brand’s page are three stars or lower, mostly no change after one to three months, and Amazon’s rating is 3.8 with 25% at one or two stars. Two reviewers with bile reflux say artichoke made their reflux worse, and a few mention cramps, worse constipation or migraines. Ashwagandha has case reports of liver injury, and artichoke carries a bile-duct and gallstone caution in drug references; the label says only to see a physician if pregnant, nursing, under 18 or with a known medical condition. Opened bottles cannot be returned under the brand’s policy.
Common questions
Does Silver Fern Motility work?
No trial of Motility itself was found. Its main ingredient, Digexin (ashwagandha and okra extracts), improved constipation symptom scores over placebo in a 135-person, 60-day trial at 300 or 500 mg a day, but the ingredient’s marketer funded it and no independent trial was found. On the brand’s page 74% of 284 reviews are five-star, while on Amazon the score is 3.8 and several reviewers report no effect after two months.
Is Motility safe, and what are its side effects?
The label says pregnant or nursing mothers, anyone under 18 and people with known medical conditions should consult a physician, and it has no ashwagandha or artichoke warning. A 2026 review found 25 reported cases of ashwagandha-associated liver injury, and consumer monographs advise against artichoke extract with bile duct blockage or gallstones. Reviewers report cramps, worse constipation and migraines in a minority, and two with bile reflux say it worsened their reflux.
How much does Motility cost?
One 60-capsule bottle is $61.12 on the brand site, which is $2.04 a day at the two-capsule serving. The brand’s moderate-to-severe tier is four capsules a day, two bottles for $105.82 or about $3.53 a day. Subscriptions take 15% off ($51.95 a bottle), and Amazon lists $66.48 a bottle, about $2.22 a day; the brand recommends at least 90 days.
What is Digexin in Motility?
Digexin is a trademarked blend of ashwagandha (Withania somnifera) root extract and okra (Abelmoschus esculentus) fruit extract, made by Laila Nutra in India and sold by NXT USA. Motility has 500 mg per serving, the top dose in its two placebo-controlled constipation trials (48 people for 14 days, 135 people for 60 days).
What is the Silver Fern refund policy?
Unopened products can be returned within 30 days with a 5% restocking fee, opened products cannot be returned, and a paid satisfaction guarantee at checkout allows a 90-day return. Silver Fern Brand has sold gut supplements since at least 2016; one reviewer on the brand’s page complained that an opened bottle could not be refunded, and the brand recommends at least 90 days of use.
