2/5 Evidence Score

Digexin® (code CL18100F4, also listed as LN20188 and NX18100F4) is a branded blend of ashwagandha (Withania somnifera) root extracts and an okra (Abelmoschus esculentus) pod extract, combined 1 to 1 and standardized to at least 5 percent polysaccharides and 0.2 percent total withanolides. It is made by Laila Nutraceuticals in India and sold to supplement brands in the US by NXT USA, which markets it for bowel regularity and the gut-brain axis. Two placebo-controlled trials in India, in 48 and 135 adults with functional constipation, tested 300 mg or 500 mg a day for 14 or 60 days and reported lower bowel symptom scores, along with better sleep and mood ratings. Only the trial summaries could be read, and they do not show whether the changes were larger than on placebo; the larger trial was funded by NXT USA. No independent group has tested the blend yet.

Studied Dose 300 mg or 500 mg once a day in both human trials (one capsule after dinner in the 14-day trial), for 14 or 60 days.
Active Compound Ashwagandha root extracts (aqueous and hydroalcoholic) and an aqueous okra fruit extract, 45 percent each plus 10 percent excipients, standardized to at least 5 percent polysaccharides and at least 0.2 percent total withanolides.

Benefits

Bowel regularity and bowel symptom scores

In two placebo-controlled trials in adults with functional constipation (48 adults for 14 days and 135 adults for 60 days), scores fell on 300 mg or 500 mg a day on the PAC-SYM bowel symptom questionnaire, the main outcome of both. The published summaries call the drop significant but do not show whether it was larger than on placebo, and both trials were small and run in India.

Gut transit time and complete bowel movements

In the 60-day trial in 135 adults with functional constipation, gut transit time was reported to shorten and complete spontaneous bowel movements to increase. These were secondary outcomes, the summary gives no figures, and the trial was funded by the company that sells the blend.

Digestive comfort and bowel-related quality of life

In both trials, scores on a digestive symptom rating scale (GSRS) and a bowel-related quality of life questionnaire (PAC-QOL) fell during treatment, reported as significant. These were secondary questionnaire outcomes in small trials, and the summaries do not show whether the scores fell more than on placebo.

Self-rated sleep quality, stress and mood

Both trials reported better self-rated sleep quality, and the trial summaries report lower stress ratings in the 14-day trial and lower anxiety and low-mood symptom scores in the 60-day trial. These were secondary outcomes in people recruited for bowel symptoms, the scales were not named in the summaries, and the effects have not been tested in stressed adults.

Blood markers linked to gut and stress signaling

In both trials, blood cortisol and IL-6 fell and serotonin, gastrin and IL-10 rose, and the 60-day trial also reported lower zonulin and higher diamine oxidase. These are laboratory markers, not health outcomes, and serotonin in blood does not show what happens in the brain.

Mechanism of action

1

Gut muscle contraction (lab and animal work)

In strips of rat small intestine, the blend increased muscle contractions in a dose-dependent way, and the effect was blocked by atropine, which points to muscarinic (acetylcholine) receptors. Rats given 200 or 300 mg/kg for 8 days had faster stomach emptying and gut transit and wetter stools, with no change in pellet count. Not yet measured in people.

2

Stress hormone and serotonin signals (animal and marker data)

In the same rat study, serum corticosterone (the rat stress hormone) fell and serotonin rose, and the human trials reported lower cortisol and higher serotonin in blood. The makers describe this as gut-brain axis activity, but no study has shown that these marker changes cause the bowel effects.

3

Two plant extracts in one blend

The blend pairs okra fruit extract, standardized to polysaccharides (the mucilage fiber), with ashwagandha root extract, standardized to withanolides. A review co-written by one trial author cites unpublished lab work for a stronger effect than either extract alone; no published study has compared them, so the role of each part is unknown.

Clinical trials

1
Digexin in adults with functional constipation: 14-day placebo-controlled pilot
PubMed

Randomized double-blind placebo-controlled single-site trial of CL18100F4 300 mg or 500 mg a day (one capsule after dinner, per the registry) for 14 days at a hospital in Guntur, India; the registered primary outcome was change in PAC-SYM score. Registered as CTRI/2020/11/029320, which names CLS Pvt Ltd (Telangana, India) as sponsor and funder. All four authors were hospital staff, none was listed at Laila Nutraceuticals, and they declared no competing interests. (Punukollu et al. 2024, J Ethnopharmacol)

48 men and women aged 25 to 60 with functional constipation by Rome III criteria.

The authors report that both doses significantly reduced PAC-SYM, PAC-QOL and GSRS scores (p < 0.0001) and improved sleep quality and stress ratings; the summary does not say whether these p values compare the blend with placebo or with baseline, and gives no placebo-group figures. On 500 mg, serum serotonin, gastrin and IL-10 rose and IL-6 and cortisol fell by the end of the study. No adverse events were reported, and blood counts, blood chemistry, vital signs and urine tests stayed in the normal range.

Digexin in adults with functional constipation: 60-day placebo-controlled trial
PubMed

Randomized double-blind placebo-controlled trial of CL18100F4 300 mg or 500 mg a day for 60 days in India (authors at hospitals in Varanasi and Guntur); primary outcome was the PAC-SYM score at days 7, 30 and 60. Funded by NXT USA, Inc. (grant 23/NXTUS/GH20, per the publisher's funding record); no registry number was found. No author was listed at Laila Nutraceuticals; one author also co-wrote a review promoting the blend. (Singh et al. 2024, J Am Nutr Assoc)

135 men and women aged 25 to 60 with functional constipation by Rome IV criteria.

The authors report that the blend significantly (p < 0.001) reduced PAC-SYM, PAC-QOL and GSRS scores and gut transit time and improved complete spontaneous bowel movements, starting from day 7, and improved sleep quality and depression and anxiety symptoms; the summary does not say whether these p values compare the blend with placebo or with baseline, and gives no placebo-group figures. Serum IL-10, diamine oxidase, serotonin and gastrin rose and IL-6, cortisol and zonulin fell. No major adverse events were seen, and laboratory tests stayed in the normal range.

Digexin and gut motility in rats (animal study)
PubMed

Laboratory study on isolated rat intestine plus an 8-day feeding study in Wistar rats at 200 and 300 mg/kg body weight. Six of the seven authors were employees of the Laila Nutra R&D department. (Annavarapu et al. 2026, Toxicol Mech Methods)

Isolated rat ileum and Wistar rats.

The blend increased intestinal contractions in a dose-dependent way, an effect blocked by atropine. In rats it improved gastric emptying, intestinal transit and stool moisture without changing pellet count, lowered serum corticosterone and raised serotonin, with no adverse changes in liver, kidney or metabolic tests. This is an animal study and does not show an effect in people.

Digexin safety testing in rats, mice and cells (animal study)
PubMed

Guideline toxicology program of LN20188 (the same blend): acute oral toxicity, a 90-day repeated-dose study in rats at 500, 1,000 and 1,500 mg/kg a day, and three genetic toxicity tests. Funded by Laila Nutra Private Limited, and all four authors were Laila employees. (Madireddy et al. 2026, Biomed Res Int)

Rats, mice, bacterial strains and human blood cells in culture.

The median lethal dose was above 2,000 mg/kg, and in the 90-day study body weight, organ weights, blood counts, blood chemistry and thyroid hormones (T3, T4 and TSH) were comparable with controls, giving a no-observed-adverse-effect level of 1,500 mg/kg, the highest dose tested. The blend did not damage genes in the three tests. Animal safety data do not establish safety in people.

Side effects and drug interactions

Common Potential side effects

In the two human trials (14 and 60 days), no adverse events or no major adverse events were reported, and blood counts, blood chemistry, vital signs and urine tests stayed in the normal range. Longer-term safety in people is unknown.
Liver: rare cases of liver injury, usually with jaundice and itching 2 to 12 weeks after starting, have been reported with ashwagandha supplements; most recovered after stopping, but people with existing liver disease have had severe outcomes, including deaths. None has been reported with this blend. Stop and see a doctor if you notice dark urine, itching, unusual tiredness or yellowing skin or eyes.
Thyroid: NCCIH says ashwagandha is not recommended for people with thyroid or autoimmune disorders or before surgery. An 8-week safety trial of an ashwagandha root extract found no change in thyroid hormones in healthy adults, and thyroid hormones did not change in a 90-day rat study of this blend.
Digestive upset and drowsiness: NCCIH lists drowsiness, stomach upset, diarrhea and vomiting among the side effects of ashwagandha preparations.
Hormones: NCCIH advises people with hormone-sensitive prostate cancer to avoid ashwagandha, because it may raise testosterone.
Pregnancy and breastfeeding: NCCIH says ashwagandha should be avoided during pregnancy and while breastfeeding; this blend has not been studied in either.

Important Drug interactions

No drug interaction studies of this blend have been published.
Thyroid medicines (such as levothyroxine): NCCIH lists thyroid hormone medicines among possible ashwagandha interactions; ask your doctor about monitoring.
Sedatives, sleep medicines and anti-seizure medicines: NCCIH lists these as possible interactions, and drowsiness may add up.
Immunosuppressants (such as cyclosporine or tacrolimus): NCCIH lists immunosuppressants among possible ashwagandha interactions; ask your doctor before combining.
Diabetes and blood pressure medicines: NCCIH lists both as possible ashwagandha interactions; ask your doctor and monitor your levels.

Frequently asked questions about Digexin® (Ashwagandha Root and Okra Pod Extract Blend)

What is Digexin?

Digexin is a branded ingredient that combines ashwagandha root extract and okra pod extract in equal parts, standardized to at least 5 percent polysaccharides and 0.2 percent total withanolides. It is made by Laila Nutraceuticals in India and sold to supplement brands in the US by NXT USA for bowel regularity and digestive comfort.

How much Digexin was used in studies?

Both human trials used 300 mg or 500 mg once a day, for 14 or 60 days; the registry for the shorter trial lists one capsule after dinner. Check the label of a finished product, since some products combine Digexin with other ingredients or use a different amount.

How strong is the evidence for bowel regularity?

Two randomized placebo-controlled trials in India, in 48 and 135 adults with functional constipation, reported lower bowel symptom scores on 300 mg or 500 mg a day. Both were short, the larger one was funded by NXT USA, and the published summaries do not show whether the improvements were larger than on placebo, so an independent trial would help confirm them.

Does Digexin work like an ashwagandha stress supplement?

Not necessarily. A 500 mg dose supplies about 225 mg of ashwagandha extract with at least about 1 mg of withanolides by the stated standardization, and its trials enrolled people for bowel symptoms, with sleep and mood as secondary outcomes. Ashwagandha cautions still apply, including rare liver injury, thyroid conditions and avoiding it in pregnancy.

What is Digexin used for?

NutraSmarts does not list Digexin under a health category. What the research covers: In two placebo-controlled trials in adults with functional constipation (48 adults for 14 days and 135 adults for 60 days), scores fell on 300 mg or 500 mg a day on the PAC-SYM bowel symptom questionnaire, the main outcome of both.

Is Digexin safe, and does it have side effects?

Side effects and cautions reported for Digexin include: In the two human trials (14 and 60 days), no adverse events or no major adverse events were reported, and blood counts, blood chemistry, vital signs and urine tests stayed in the normal range. Longer-term safety in people is unknown. It may also interact with some medications. Digexin is not right for everyone, so check with a healthcare provider first if you are pregnant or breastfeeding, have a medical condition, or take prescription medication.

Does Digexin interact with any medications?

Possible interactions include: No drug interaction studies of this blend have been published. Thyroid medicines (such as levothyroxine): NCCIH lists thyroid hormone medicines among possible ashwagandha interactions; ask your doctor about monitoring. If you take prescription medication, check with a pharmacist or doctor before using it.
