HelloPharmacist Scorecard of Flush & Be Fit by Renew Life Brenda Watson's Vital Woman

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.

From our pharmacy team — supplement deep dive

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 1 of its 36 active ingredients.
  • “L. reuteri” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.
  • “WomanEnergy Blend” is a proprietary blend — the label gives one combined amount (900 mg) without saying how much of each component you get.
  • “WomanDigest Blend” is a proprietary blend — the label gives one combined amount (102 mg) without saying how much of each component you get.

Flush & Be Fit contains 36 ingredients total. The active components include digestive enzymes (protease and lipase), botanical extracts (cayenne, burdock, dandelion, ginger, Cape Aloe, horsetail, wild indigo, red clover, cranberry, green tea, marshmallow, quercetin, yerba mate, ashwagandha, gotu kola, and bitter orange), taurine, and a probiotic blend (L. reuteri), plus a proprietary WomanEnergy Blend.

The inactive ingredients consist of a vegetable capsule. The formula combines traditional digestive and detoxification herbs with enzymes meant to support digestion and a probiotic strain.

Several of these botanicals are also used to support women's wellness, though the specific roles and potencies of individual ingredients in this blend are not detailed on the label.

Does it work?

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: detox, energy, and bowel regularity for women.
  • We looked for evidence on: Antibiotic-associated diarrhea, Atopic dermatitis (eczema), constipation, fatigue, bloating, urinary tract health.
  • The strongest evidence on file: Magnesium is rated "Effective" for Constipation (Natural Medicines).
  • Also on file: Saccharomyces Boulardii is rated "Possibly Effective" for Antibiotic-associated diarrhea.
  • Also on file: Aloe is rated "Possibly Effective" for Constipation.

The evidence for most ingredients in this product is limited or mixed. Ginger is possibly effective for pregnancy-induced nausea, muscle soreness relief, and dysmenorrhea, though it rated possibly ineffective for chemotherapy-induced nausea.

Cape Aloe is possibly effective for acne, burns, constipation, psoriasis, obesity, and diabetes. Cranberry is possibly effective for urinary tract infections.

Green tea is likely effective for human papillomavirus (HPV) and possibly effective for ovarian cancer and high cholesterol. For many other ingredients — burdock, dandelion, horsetail, wild indigo, red clover, marshmallow, quercetin, ashwagandha, gotu kola, and bitter orange — the evidence we hold is rated insufficient to say whether they work for their intended uses.

Protease and lipase are rated insufficient for inflammatory bowel disease and indigestion. Taurine is possibly effective for hepatitis and congestive heart failure but possibly ineffective for obesity.

Overall, this is a broad-spectrum formula with unproven or limited evidence for many of its active ingredients.

The evidence, ingredient by ingredient Magnesium

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 28 of the 29 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 29 of 29.
  • General safety write-ups exist for 29 of 29.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most ingredients in this product are generally well tolerated at typical doses, though several come with cautions. Taurine is generally well tolerated short-term but long-term safety is less certain; rare hypersensitivity reactions and cases of cardiovascular events in energy drinks have been reported, though it's unclear if taurine alone was responsible.

Common side effects from these ingredients include mild gastrointestinal upset — constipation, diarrhea, heartburn, nausea, gas, and bloating. Cape Aloe and horsetail carry more serious concerns.

Aloe latex can cause significant potassium loss, especially with long-term use, and carries risks with diuretics and heart medications. Horsetail contains thiaminase, which can cause thiamine (vitamin B1) deficiency with prolonged use; Canadian products are required to be thiaminase-free.

Ashwagandha and gotu kola have been linked to rare cases of liver toxicity in case reports. Taurine is rated likely safe in pregnancy and lactation, but ginger is rated possibly safe to likely safe depending on the trimester, while Cape Aloe, horsetail, wild indigo, dandelion, red clover, ashwagandha, and marshmallow are rated unsafe or have insufficient safety data — pregnancy and breastfeeding data are not on file for several ingredients.

Talk with your doctor or pharmacist about your own pregnancy or breastfeeding status before starting.

Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 26 of the 29 matched ingredients can interact with medications — Burdock, Milk Thistle, Rhubarb, Quercetin, Red Clover, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; cancer treatments; diabetes medications; heart-rhythm medications; lithium; Parkinson's medications.
  • For scale: 2,365 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, double-check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs (such as warfarin, aspirin, clopidogrel), heart medications (digoxin, beta-blockers like nadolol, calcium channel blockers like nifedipine, ACE inhibitors), diabetes drugs, lithium, seizure medications (phenytoin, valproate, felbamate), or any drug metabolized by CYP3A4 enzymes. The caffeine-containing ingredients (green tea, yerba mate) and bitter orange can also interact with stimulants, certain antidepressants, and other drugs.

No interactions are documented for amylase, red root, or Korean ginseng — these ingredients were not checked.

Each ingredient & the kinds of drugs it affects

For each ingredient in Flush & Be Fit with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.

Magnesium15 drug types · 295 drugs

Levodopa/Carbidopa (Sinemet)

Magnesium can reduce the bioavailability of levodopa/carbidopa.
Clinical research in healthy volunteers shows that taking magnesium oxide 1000 mg with levodopa 100 mg/carbidopa 10 mg reduces the area under the curve (AUC) of levodopa by 35% and of carbidopa by 81%. In vitro and animal research shows that magnesium produces an alkaline environment in the digestive tract, which might lead to degradation and reduced bioavailability of levodopa/carbidopa.

Likelihood Probable Evidence B
Aminoglycoside Antibiotics

Concomitant use of aminoglycoside antibiotics and magnesium can increase the risk for neuromuscular weakness.
Both aminoglycosides and magnesium reduce presynaptic acetylcholine release, which can lead to neuromuscular blockade and possible paralysis. This is most likely to occur with high doses of magnesium given intravenously.

Likelihood Possible Evidence D
Antacids

Use of acid reducers may reduce the laxative effect of magnesium oxide.
A retrospective analysis shows that, in the presence of H2 receptor antagonists (H2RAs) or proton pump inhibitors (PPIs), a higher dose of magnesium oxide is needed for a laxative effect. This may also occur with antacids. Under acidic conditions, magnesium oxide is converted to magnesium chloride and then to magnesium bicarbonate, which has an osmotic laxative effect. By reducing acidity, antacids may reduce the conversion of magnesium oxide to the active bicarbonate salt.

Likelihood Possible Evidence D
Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)

Magnesium might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide should be taken at least 2 hours before or 6 hours after magnesium containing products.

Likelihood Probable Evidence D
Bisphosphonates

Magnesium can decrease absorption of bisphosphonates.
Cations, including magnesium, can decrease bisphosphonate absorption. Advise patients to separate doses of magnesium and these drugs by at least 2 hours.

Likelihood Probable Evidence B
Calcium Channel Blockers

Magnesium can have additive effects with calcium channel blockers, although evidence is conflicting.
Magnesium inhibits calcium entry into smooth muscle cells and may therefore have additive effects with calcium channel blockers. Severe hypotension and neuromuscular blockades may occur when nifedipine is used with intravenous magnesium, although some contradictory evidence suggests that concurrent use of magnesium with nifedipine does not increase the risk of neuromuscular weakness. High doses of magnesium could theoretically have additive effects with other calcium channel blockers.

Likelihood Possible Evidence D
Digoxin

Magnesium salts may reduce absorption of digoxin.
Clinical evidence suggests that treatment with oral magnesium hydroxide or magnesium trisilicate reduces absorption of digoxin from the intestines. This may reduce the blood levels of digoxin and decrease its therapeutic effects.

Likelihood Possible Evidence B
Potassium-Sparing Diuretics

Potassium-sparing diuretics decrease excretion of magnesium, possibly increasing magnesium levels.
Potassium-sparing diuretics also have magnesium-sparing properties, which can counteract the magnesium losses associated with loop and thiazide diuretics. Theoretically, increased magnesium levels could result from concomitant use of potassium-sparing diuretics and magnesium supplements.

Likelihood Probable Evidence D
Quinolone Antibiotics

Magnesium decreases absorption of quinolones.
Magnesium can form insoluble complexes with quinolones and decrease their absorption. Advise patients to take these drugs at least 2 hours before, or 4 to 6 hours after, magnesium supplements.

Likelihood Probable Evidence D
Skeletal Muscle Relaxants

Parenteral magnesium alters the pharmacokinetics of skeletal muscle relaxants, increasing their effects and accelerating the onset of effect.
Parenteral magnesium shortens the time to onset of skeletal muscle relaxants by about 1 minute and prolongs the duration of action by about 2 minutes. Magnesium potentiates the effects of skeletal muscle relaxants by decreasing calcium-mediated release of acetylcholine from presynaptic nerve terminals, reducing postsynaptic sensitivity to acetylcholine, and having a direct effect on the membrane potential of myocytes. Magnesium also has vasodilatory actions and increases cardiac output, allowing a greater amount of muscle relaxant to reach the motor end plate. A clinical study found that low-dose rocuronium (0.45 mg/kg), when given after administration of magnesium 30 mg/kg over 10 minutes, has an accelerated onset of effect, which matches the onset of effect seen with a full-dose rocuronium regimen (0.6 mg/kg). In another clinical study, onset times for rocuronium doses of 0.3, 0.6, and 1.2 mg/kg were 86, 76, and 50 seconds, respectively, when given alone, but were reduced to 66, 44, and 38 seconds, respectively, when the doses were given after a 15-minute infusion of magnesium sulfate 60 mg/kg. Giving intraoperative intravenous magnesium sulfate, 50 mg/kg loading dose followed by 15 mg/kg/hour, reduces the onset time of rocuronium, enhances its clinical effects, reduces the dose of intraoperative opiates, and prolongs the spontaneous recovery time. It does not affect the activity of subsequently administered neostigmine.

Likelihood Probable Evidence A
Sulfonylureas

Magnesium increases the systemic absorption of sulfonylureas, increasing their effects and side effects.
Clinical research shows that administration of magnesium hydroxide with glyburide increases glyburide absorption, increases maximal insulin response by 35-fold, and increases the risk of hypoglycemia, when compared with glyburide alone. A similar interaction occurs between magnesium hydroxide and glipizide. The mechanism of this effect appears to be related to the elevation of gastrointestinal pH by magnesium-based antacids, increasing solubility and enhancing absorption of sulfonylureas.

Likelihood Probable Evidence B
Tetracycline Antibiotics

Magnesium decreases absorption of tetracyclines.
Magnesium can form insoluble complexes with tetracyclines in the gut and decrease their absorption and antibacterial activity. Advise patients to take these drugs 1 hour before or 2 hours after magnesium supplements.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, magnesium may have antiplatelet effects, but the evidence is conflicting.
In vitro evidence shows that magnesium sulfate inhibits platelet aggregation, even at low concentrations. Some preliminary clinical evidence shows that infusion of magnesium sulfate increases bleeding time by 48% and reduces platelet activity. However, other clinical research shows that magnesium does not affect platelet aggregation, although inhibition of platelet-dependent thrombosis can occur.

Likelihood Unlikely Evidence B
Gabapentin (Neurontin)

Gabapentin absorption can be decreased by magnesium.
Clinical research shows that giving magnesium oxide orally along with gabapentin decreases the maximum plasma concentration of gabapentin by 33%, time to maximum concentration by 36%, and area under the curve by 43%. Advise patients to take gabapentin at least 2 hours before, or 4 to 6 hours after, magnesium supplements.

Likelihood Unlikely Evidence B
Sevelamer (Renagel, Renvela)

Sevelamer may increase serum magnesium levels.
In patients on hemodialysis, sevelamer use was associated with a 0.28 mg/dL increase in serum magnesium. The mechanism of this interaction remains unclear.

Flush & Be Fit by Renew Life Brenda Watson's Vital Woman: Common Questions

Does Flush & Be Fit by Renew Life Brenda Watson's Vital Woman interact with any medications?
Yes. Based on its ingredients, Flush & Be Fit has a known interaction with 2,364 medications, including 30 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Flush & Be Fit contains 7 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is this product safe to take while pregnant or breastfeeding?
Several ingredients carry warnings against use in pregnancy — Cape Aloe, horsetail, wild indigo, dandelion, red clover, ashwagandha, marshmallow, and quercetin are rated unsafe or have insufficient safety data. Ginger is rated possibly to likely safe in small amounts. Because the data vary by ingredient and personal circumstances matter, talk with your doctor or pharmacist before taking this product if you are pregnant, planning to become pregnant, or breastfeeding.
What are the most common side effects I might experience?
Mild gastrointestinal effects are most common — constipation, diarrhea, heartburn, nausea, gas, and bloating. Ginger can cause burning sensations in the mouth and throat. These effects are usually mild and often dose-dependent, improving if you take the product with food or in smaller amounts.
Can I take this if I'm on a blood thinner like warfarin?
No — without checking first. Several ingredients in this product (cayenne, dandelion, ginger, aloe, cranberry, and red clover) may increase bleeding risk, and ginger and aloe have specific case reports with warfarin. Talk with your doctor or pharmacist before starting; they can advise whether this product is safe for you or if you need to adjust your medication.
Does this product help with digestion?
The product contains digestive enzymes (protease and lipase) and a probiotic (L. reuteri), which are commonly used to support digestive function. However, the evidence we hold for lipase and protease in supplements is rated insufficient — we don't have strong proof they work for indigestion or bowel conditions. If you have a digestive concern, talk with your doctor about whether this is the right choice for you.
What if I take diabetes or seizure medications?
You need to check with your pharmacist. Ginger, dandelion, and ashwagandha may lower blood sugar and increase the risk of hypoglycemia (low blood sugar). Green tea, yerba mate, and bitter orange contain caffeine and can interfere with seizure medications. Don't start this product without confirming it's safe with your specific drugs and doses.
Is the L. reuteri probiotic in this product well studied?
L. reuteri is a probiotic strain that appears in several supplements, but the product facts we hold do not provide details on its individual effectiveness or safety profile — it is listed as a blend ingredient. If probiotics are important to your health, ask your pharmacist or doctor whether this specific strain and dose are right for you.
