HelloPharmacist Scorecard of FiberMode Unflavored by Evlution Nutrition
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
FiberMode Unflavored has four active ingredients. Polydextrose and inulin are both soluble fibers that work to add bulk and support digestion.
Psyllium is another fiber, though we don't hold interaction data for it. ProDURA is a probiotic — a live beneficial organism (Bacillus coagulans) meant to support digestive health.
Does it work?
Strong evidence
The evidence here is mixed. Inulin is rated possibly effective for constipation, diabetes, and obesity.
Bacillus coagulans (ProDURA) is rated possibly effective for constipation and irritable bowel syndrome (IBS). Polydextrose, however, doesn't have enough reliable evidence in our data to rate it for any condition — the same goes for most of the other uses listed.
If you're taking this for a specific digestive concern, talk with your pharmacist about whether the evidence supports its use for your situation.
How safe is it?
Well-documented data
Polydextrose and inulin are generally well tolerated at food amounts, but both commonly cause gas, bloating, and loose stools — especially inulin at doses over 30 grams, and polydextrose at doses over 50 grams daily. Start low and increase gradually to let your gut adjust.
Bacillus coagulans is generally well tolerated in healthy people, though the safety data is limited and product quality varies. There is rare concern that live probiotics might cause infection in people with central catheters or severely weakened immune systems, but this is not a typical concern for otherwise healthy people.
Pregnancy and lactation data on polydextrose and Bacillus coagulans are not on file; inulin is rated likely safe in pregnancy and lactation.
Meds to double-check
Moderate interaction found
If you take antibiotics, separate them from this product — the antibiotic can kill the probiotic organisms and make this supplement less effective. If you take diabetes medications, be aware of the minor risk of low blood sugar when combined with inulin; your pharmacist can help you monitor for this.
No other interactions are documented for the ingredients we could check.
The bottom line
Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This is a fiber and probiotic blend that may help with constipation or IBS, though the evidence is stronger for some ingredients than others. If you take antibiotics or diabetes medications, check with your pharmacist first — timing matters with the antibiotic, and the diabetes drug interaction, though minor, warrants a conversation.
Start with a small dose to see how your gut tolerates it.

FiberMode Unflavored by Evlution Nutrition Drug Interactions
HelloPharmacist Interaction Report
FiberMode Unflavored by Evlution Nutrition contains a probiotic ingredient, Bacillus coagulans (ProDURA), that interacts with antibiotics.
If you take an antibiotic, the medication can kill the live organisms in this product, making the probiotic less effective. The data suggests separating when you take them — ask your pharmacist about the right timing for your specific antibiotic.
Read the full breakdown — every affected drug type, severity by severity
Inulin, another ingredient here, carries a minor interaction with diabetes medications. It might theoretically increase the risk of low blood sugar (hypoglycemia) when combined with antidiabetes drugs, though research on whether inulin actually lowers blood sugar is mixed.
We could not check the interaction data for psyllium, one of the four active ingredients, so we don't hold interaction information for it. Altogether, these interactions span 267 individual medications.

For each ingredient in FiberMode Unflavored with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Dietary Fiber
Carbamazepine (Tegretol)
Theoretically, black psyllium might reduce the effects of carbamazepine and increase the risk for convulsions.
Theoretically, black psyllium might reduce carbamazepine absorption. A preliminary study using blond psyllium reported decreased carbamazepine bioavailability due to binding of the drug to psyllium, as well as reduction of available fluid in the gut for dissolution of the drug. This interaction may also occur with black psyllium.
Lithium
Theoretically, taking black psyllium at the same time as lithium might reduce lithium absorption.
The fiber in black psyllium might reduce lithium absorption and plasma levels. Some case reports describe a reduction in plasma lithium levels with concomitant administration of blond psyllium. This was reversed when psyllium was stopped. This interaction may also occur with black psyllium.
Metformin (Glucophage)
Theoretically, black psyllium might increase the therapeutic and adverse effects of metformin.
Animal research shows that concurrent consumption of blond psyllium with metformin slows and increases the absorption of metformin. This interaction may also occur with black psyllium. To avoid changes in absorption, take psyllium 30-60 minutes after metformin.
Olanzapine (Zyprexa)
Theoretically, taking black psyllium at the same time as olanzapine might reduce olanzapine absorption.
The fiber in black psyllium might decrease the absorption of olanzapine. A single case report describes a reduction in the effectiveness of olanzapine when it was concomitantly administered with an unspecified type of psyllium 3 grams orally twice daily. This effect was reversed when psyllium was stopped.
Digoxin (Lanoxin)
Theoretically, taking black psyllium at the same time as digoxin might reduce digoxin absorption and decrease digoxin levels.
Psyllium might bind digoxin in the gut. However, some clinical evidence suggests that psyllium does not impact digoxin absorption.
Ethinyl Estradiol
Theoretically, taking black psyllium at the same time as ethinyl estradiol might alter levels of estradiol.
Concurrent use of blond psyllium with ethinyl estradiol results in a slight increase in the extent of ethinyl estradiol absorption and a slower rate of absorption. This is unlikely to be clinically significant.
Oral Drugs
Theoretically, psyllium might increase, decrease, or have no effect on the absorption of oral drugs.
Psyllium seems to have variable effects on drug absorption. To avoid changes in absorption, take psyllium 30-60 minutes after oral medications. Animal research shows that blond psyllium delays and increases the absorption of metformin and ethinyl estradiol. Case reports and animal research suggest that blond psyllium might reduce absorption of lithium, digoxin, olanzapine, and carbamazepine. Finally, some pharmacokinetic studies show that psyllium does not affect the absorption of levothyroxine or warfarin. Although many of these studies evaluated blond psyllium, the fiber content in black psyllium may have similar effects.
ProDURA
Antibiotic Drugs
Theoretically, taking antibiotics with Bacillus coagulans might decrease the effectiveness of B. coagulans.
B. coagulans preparations usually contain live and active organisms. Therefore, simultaneously taking antibiotics might kill a significant number of the organisms. Tell patients to separate administration of antibiotics and B. coagulans preparations by at least two hours.
Inulin
Antidiabetes Drugs
Theoretically, inulin might increase the risk of hypoglycemia with antidiabetes drugs.
Some clinical research shows that inulin improves glycemic control in patients with diabetes; however, it is unclear if it has hypoglycemic effects.
