HelloPharmacist Scorecard of Bifidus by New Earth
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
Low disclosure
Bifidus contains three active ingredients in a proprietary blend. Inulin is a fiber that feeds beneficial gut bacteria.
Organic microalgae (blue-green algae/spirulina) is an algae concentrate. Bifidobacterium bifidum is a live probiotic — a beneficial bacterium — intended to support digestive and immune health.
The product also contains inactive ingredients: plant fiber, cellulose, and fructooligosaccharide (a type of sugar that feeds good bacteria).
Does it work?
Strong evidence
Inulin is possibly effective for constipation, diabetes, and obesity. The blue-green algae is possibly effective for high blood pressure.
Bifidobacterium bifidum is possibly effective for irritable bowel syndrome (IBS) and respiratory tract infections. For other uses listed on the product — such as acne, hay fever, and anemia — the evidence isn't established in the data we hold.
How safe is it?
Well-documented data
Inulin is likely safe in pregnancy and lactation. Inulin is well tolerated overall but often causes gas, bloating, diarrhea, constipation, and cramping, especially at higher doses over 30 grams.
The blue-green algae carries quality and contamination risks; safety data is limited, and some products may contain toxins or heavy metals. Allergic reactions including rashes, anaphylaxis (very rare), and mild bleeding have been reported.
Bifidobacterium bifidum is generally well tolerated in healthy people, though those with weakened immune systems should check with their doctor. Bloating and flatulence can occur with probiotics.
Pregnancy and lactation data for the microalgae and probiotic are not on file; talk with your doctor or pharmacist before use if you're pregnant or breastfeeding.
Meds to double-check
Moderate interaction found
Before you start, double-check if you take blood thinners or antiplatelet drugs (Moderate interaction with the algae component). Also flag diabetes medications (Moderate to Minor risk of low blood sugar), immune-suppressing drugs (Moderate), and any antibiotics (Moderate — space them apart from the probiotic).
If you take any of these, run them through the checker below.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Bifidus may help constipation, IBS, or blood sugar control if you're not on other medications for those conditions. If you take diabetes drugs, blood thinners, antibiotics, or immune-suppressing medications, you'll want to check this product first — several ingredient interactions could affect how your drugs work.
Talk with your pharmacist about timing and whether it's right for you.

Bifidus by New Earth Drug Interactions
HelloPharmacist Interaction Report
Bifidus by New Earth contains three active ingredients, and together they interact with a significant number of medications.
The most serious interaction comes from the organic microalgae (spirulina blue-green algae), which has a Moderate-severity interaction with blood thinners and antiplatelet drugs — it may theoretically increase bleeding risk, though this is unlikely in practice.
Read the full breakdown — every affected drug type, severity by severity
Inulin and the microalgae also interact with diabetes medications at Moderate to Minor severity, both theoretically raising the risk of low blood sugar (hypoglycemia). The microalgae additionally has a Moderate interaction with immune-suppressing drugs, as it may stimulate your immune system and potentially interfere with their intended effect.
Bifidobacterium bifidum — the probiotic component — has a Moderate interaction with antibiotics; if you take them together, the antibiotic may kill the live organisms in the probiotic and make it less effective. It's best to space them apart.
Altogether, these interactions span 502 individual medications. Use the medication checker on this page to look up your specific drugs before you start.

For each ingredient in Bifidus 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.
organic Microalgae
Anticoagulant/Antiplatelet Drugs
Theoretically, spirulina blue-green algae might increase the risk of bleeding if used with other anticoagulant or antiplatelet drugs. However, this is unlikely.
Spirulina blue-green algae have shown antiplatelet and anticoagulant effects in vitro. However, one preliminary study in 24 patients receiving spirulina blue-green algae 2.3 grams daily for 2 weeks showed no effect on platelet activation or measures of clotting time.
Antidiabetes Drugs
Theoretically, taking blue-green algae with antidiabetes drugs might increase the risk of hypoglycemia.
Human research shows that spirulina blue-green algae can have hypoglycemic effects in patients with diabetes, at least some of whom were using antidiabetes drugs. However, blue-green algae does not seem to improve glycated hemoglobin (HbA1c) levels in patients with diabetes. A meta-analysis of animal studies also suggests that spirulina blue-green algae have hypoglycemic effects.
Immunosuppressants
Theoretically, concurrent use of blue-green algae might interfere with immunosuppressive therapy.
Blue-green algae have been shown to stimulate the immune system.
Bifidobacterium bifidum
Antibiotic Drugs
Theoretically, taking Bifidobacterium. bifidum with antibiotic drugs might decrease the effectiveness of B. bifidum.
Since B. bifidum preparations usually contain live and active organisms, simultaneously taking antibiotics might kill a significant number of the organisms. Tell patients to separate administration of antibiotics and B. bifidum preparations by at least 2 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.
