Consolax® (Soluble and Insoluble Fiber Blend — Zeus Hygia)

Evidence Level

2/5 Evidence Score

Consolax® is a balanced blend of soluble and insoluble plant fibers from Zeus Hygia, formulated to support regular bowel movements, ease occasional constipation, and promote a healthy gut microbiome. Zeus Hygia's own listings name psyllium husk and chicory extract among the fibers, and the supplier suggests 1.8 g twice a day. No published human trial has tested Consolax itself, so everything below comes from studies of the fiber types it contains, at daily doses well above the suggested serving.

Studied Dose Zeus Hygia suggests 1.8 g twice a day, about 3.6 g of fiber daily. The studies this page rests on used more: 5 g twice daily in the constipation trial, and 5 g to 20 g a day of inulin in the microbiome review. No dose of Consolax itself has been tested in a trial.
Active Compound Blend of soluble and insoluble plant fibers; Zeus Hygia names psyllium husk and chicory extract among them, in a ratio the supplier does not disclose.

Benefits

Bowel regularity

Soluble fiber of the kind Consolax contains supports regular, comfortable bowel movements and can ease occasional constipation. In a review of four small soluble fiber trials, more people reported overall improvement on fiber than on placebo, 86.5 percent against 47.4 percent, and weekly stools rose from 2.9 before treatment to 3.8 after, a little under one extra movement a week. The reviewers judged the trials too weak to pool formally and found the evidence for insoluble fiber conflicting. Consolax itself has not been tested.

Microbiome support

Inulin, the fiber in chicory extract, raised Bifidobacterium counts fairly consistently across nine human studies at 5 g to 20 g a day. Those studies counted which bacteria were present rather than measuring how people felt, and the same review reported the bacterial shift was not matched by a rise in short-chain fatty acids. A change in the mix of gut bacteria is not by itself a health benefit.

Digestive comfort

In a four week trial of a mixed soluble and insoluble fiber, which was not Consolax, straining and bloating scores fell on both that fiber and the psyllium it was compared against, and more people on the mixed fiber said their flatulence improved, 53 percent against 25 percent. There was no placebo group, so part of the improvement in both arms may not be down to the fiber at all. Adding fiber also commonly causes gas and bloating at first, so comfort can get worse before it gets better.

Mechanism of action

1

Stool bulking and softening

Insoluble fiber adds bulk while soluble fiber holds water, together easing passage and supporting regularity.

2

Prebiotic fermentation

Fermentable soluble fiber is converted by gut bacteria into short-chain fatty acids that nourish the colon. Fiber of this kind also encourages Bifidobacteria. In the human inulin studies behind this page the rise in Bifidobacterium did show up, but the expected rise in short-chain fatty acids did not.

Clinical trials

Side effects and drug interactions

Common Potential side effects

Generally well tolerated as a fiber, though the review behind this page noted that the trials reported little adverse event data and none gave total numbers.
Gas or bloating can occur as fiber intake rises.
Increase the dose gradually and take each serving with a full glass of water. Bulk-forming fiber such as psyllium swells as it absorbs liquid, so taking it with too little fluid can let it lodge in the throat or gut. Do not take it if you have trouble swallowing, and get medical help if you get chest pain, vomiting, or difficulty swallowing or breathing after a dose.

Important Drug interactions

Generally compatible with medications.
May slow absorption of some medications; a common precaution is to take other medicines at least an hour before or two hours after a fiber dose.
Tell your doctor if you have a serious digestive condition. Constipation that persists, or any new change in your usual bowel habit, needs a doctor rather than a fiber supplement, and anyone with a history of bowel obstruction or a narrowed bowel should not start bulk fiber without medical advice.

Both arms improved and neither beat the other. Responders were 75% on mixed fiber and 75% on psyllium (P=0.9), and complete spontaneous bowel movements, stool consistency, straining, bloating and quality of life all improved in both arms without a group difference. Mixed fiber beat psyllium only on reported improvement in flatulence (53% vs 25%, P=0.01) and on dissolving better (P=0.02). Different material, different supplier, and nearly three times the suggested Consolax serving, so it supports the fiber class rather than the product. Zeus Hygia's listings say Consolax contains psyllium, which was the comparator arm here.

Only six randomized trials were eligible, four of soluble fiber and two of insoluble, and the authors did not pool them formally because of concerns about methodological quality. They called the insoluble fiber data conflicting and asked for better trials before the true efficacy of either fiber type is known. Supports the soluble fiber part of a blend like Consolax, not Consolax itself

The review also reported that these bacterial changes were not accompanied by higher short-chain fatty acid levels. It assessed gut microbial composition only, not symptoms or any other health outcome. Relevant to the chicory inulin Zeus Hygia lists in Consolax, at doses well above the suggested serving, and a change in bacterial composition is not itself a health benefit
