Per daily pack
1 sachet + 3 capsules
Daily Ritual
Each pack contains one fiber sachet and three capsules — everything you need, pre-sorted for the day.
Stir the lemonade-flavored fiber powder into a full glass of cold or room-temperature water and drink immediately.
The magnesium citrate and probiotic capsules can be taken with the sachet or later in the day — whatever fits your routine.
Best taken in the morning before breakfast. Results typically noticed within 3–7 days.

The System
Psyllium Husk + PHGG (Sunfiber®)
Psyllium at 10g/day is the gold standard for bowel regularity, proven in meta-analyses to add +3 bowel movements per week. PHGG reduces gas and bloating while feeding your probiotic strains.
Magnesium Citrate
Draws water into the colon for predictably soft, comfortable stools. Citrate form is well-absorbed and gentle — no harsh cramping, no dependency.
B. lactis HN019 + L. reuteri DSM 17938
HN019 is one of the most clinically studied strains for gut motility, confirmed in a 2024 JAMA Network Open RCT. L. reuteri DSM 17938 independently increases bowel movement frequency.
Green Kiwifruit Extract (Actazin®)
Actinidin enzyme enhances gastric emptying and protein digestion. A 2024 RCT (85 participants, 28 days) confirmed significant improvements in stool form and bowel habits.
The Evidence
10g/day psyllium significantly increases bowel movement frequency vs. placebo across multiple systematic reviews.
B. lactis HN019 at 20B CFU confirmed to increase complete spontaneous bowel movements in 8-week RCT.
600mg green kiwifruit extract showed clinically significant stool form improvement in 85-participant trial.
