HelloPharmacist Scorecard of Flex Mobility by NOW
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
Flex Mobility contains 5 active ingredients. Bromelain is an enzyme from pineapple that may have anti-inflammatory properties.
Regenasure Glucosamine HCl is a compound that supports joint structure. FlavanFlex is a plant-derived ingredient.
Boswellin is an extract of frankincense resin, traditionally used in joint and mobility support. Devil's claw extract comes from a southern African plant root, also used for joint comfort.
The capsules also contain inactive ingredients (cellulose, rice flour, stearic acid, magnesium stearate, silica, and maltodextrin) that serve as fillers and binders.
Does it work?
Moderate evidence
The evidence is sparse for most uses in this product. Bromelain has insufficient reliable evidence for hay fever, burns, cancer, chemotherapy nerve damage, vein insufficiency, and diabetes.
Boswellin also shows insufficient evidence for acne, aging skin, back pain, cancer fatigue, and radiation skin damage. Devil's claw is possibly effective for back pain and osteoarthritis, but shows insufficient evidence for atherosclerosis.
How safe is it?
Well-documented data
Bromelain and devil's claw are generally well tolerated for short-term use, though long-term safety data is limited for both. The most common side effects from bromelain are diarrhea, flatulence, stomach upset, and headache when taken by mouth.
Devil's claw may cause allergic skin reactions, diarrhea, and indigestion—8 to 18% of users report digestive complaints, especially at higher doses. Rarely, devil's claw has caused gastrointestinal bleeding and neurological symptoms like headache, dizziness, and sleep disturbance in case reports.
Both bromelain and devil's claw may trigger allergic reactions, including asthma or throat swelling if inhaled. Bromelain is not recommended during pregnancy and should be avoided while breastfeeding.
Devil's claw is possibly unsafe in pregnancy because it may affect the uterus, and safety while breastfeeding is not established. Data on Boswellin and pregnancy or breastfeeding advises against use.
We hold no pregnancy or breastfeeding data for Regenasure Glucosamine HCl and FlavanFlex.
Meds to double-check
Moderate interaction found
Check with your doctor or pharmacist before using this product if you take blood thinners or antiplatelet drugs (like warfarin or aspirin)—bromelain may increase bleeding risk. Also clear it if you use warfarin or other medications metabolized by CYP2C19, CYP2C9, or CYP3A4 enzymes (a very broad category including many heart, blood pressure, and psychiatric drugs), or if you take acid-reflux medications like H2-blockers or proton pump inhibitors.
Devil's claw may theoretically raise levels of these drugs or interfere with acid control.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Flex Mobility may be worth considering if you're interested in joint and mobility support and have no contraindications—but you'll want to be careful if you take blood thinners, antiplatelet drugs, warfarin, or medications your liver breaks down (especially via the CYP2C9, CYP2C19, or CYP3A4 pathways), or if you use acid-reflux medications. Talk with your doctor or pharmacist about whether this product is right for your medications and health before you start.

Flex Mobility by NOW Drug Interactions
HelloPharmacist Interaction Report
Flex Mobility by NOW contains bromelain and devil's claw extract, both of which interact with medications.
The most serious concern is bromelain's moderate interaction with blood thinners and antiplatelet drugs (anticoagulants and antiplatelet medications)—it may increase bleeding risk by thinning the blood further.
Read the full breakdown — every affected drug type, severity by severity
Devil's claw carries moderate interactions with a large group of drugs metabolized by your liver, including warfarin and many others processed through CYP2C19, CYP2C9, and CYP3A4 pathways. It may also theoretically raise warfarin levels and increase over-anticoagulation.
Additionally, devil's claw may weaken acid-reflux medications (H2-blockers and proton pump inhibitors) by increasing stomach acid.
Bromelain carries a minor interaction with tetracycline antibiotics, though studies suggest it may not be a real concern in practice. Devil's claw has a minor interaction with P-glycoprotein substrates (a broad category of drugs).
We could not check Regenasure Glucosamine HCl and FlavanFlex because interaction data is not on file for them. Boswellin (frankincense) was checked and no interactions are documented in our data.
Altogether, these interactions span 877 individual medications. Check your exact medications with the search tool on this page before you start.

For each ingredient in Flex Mobility 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.
Devil's Claw extract
Cytochrome P450 2C19 (Cyp2C19) Substrates
Theoretically, devil's claw might increase levels of drugs metabolized by CYP2C19.
In vitro research shows that devil's claw might inhibit CYP2C19, although this has not been reported in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, devil's claw might increase levels of drugs metabolized by CYP2C9.
In vitro research shows that devil's claw might inhibit CYP2C9, although this has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, devil's claw might increase levels of drugs metabolized by CYP3A4.
In vitro research shows that devil's claw might inhibit CYP3A4, although this has not been reported in humans.
Warfarin (Coumadin)
Theoretically, Devil's claw might increase the activity of warfarin.
In one case report, purpura occurred in a patient taking warfarin and devil's claw concurrently. This might indicate over-anticoagulation. It is unclear if this was due to Devil's claw or other contributing factors.
H2-Blockers
Theoretically, devil's claw might decrease the effectiveness of H2-blockers.
Devil's claw has been reported to increase stomach acid, which might interfere with the effects of H2-blockers.
P-Glycoprotein Substrates
Theoretically, devil's claw might increase levels of P-glycoprotein substrates.
In vitro research shows that devil's claw inhibits P-glycoprotein, which transports many drugs out of cells. This might increase intracellular levels of P-glycoprotein substrates, although it is unclear if this effect would be clinically important.
Proton Pump Inhibitors (Ppis)
Theoretically, devil's claw might decrease the effectiveness of PPIs.
Devil's claw has been reported to increase stomach acid, which might interfere with the effects of PPIs.
Bromelain
Anticoagulant/Antiplatelet Drugs
Bromelain may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
There is one case report of a patient experiencing minor bruising while taking bromelain with naproxen. Bromelain is thought to have antiplatelet activity. Whether this interaction is of concern with topical bromelain is unclear. Interference with coagulation of burn wounds has been reported in a patient receiving bromelain-based enzymatic debridement. However, observational research has found that topical bromelain debridement is not associated with increases or decreases in laboratory markers of coagulation when compared with surgical debridement.
Tetracycline Antibiotics
Theoretically, bromelain might increase levels of tetracycline antibiotics.
Laboratory research suggests that bromelain might increase the absorption of tetracycline antibiotics. However, a study in healthy adults reported no difference in tetracycline plasma levels when a 500 mg dose was taken with or without bromelain 80 mg.
