HelloPharmacist Scorecard of Ultimate Strength Raspberry Ketone Flush by New Health Corp.

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

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains three active ingredients. Raspberry ketone is a compound extracted from raspberries that's being studied for weight loss and hair loss, though the evidence isn't firm yet.

Cascara sagrada bark powder is a stimulant laxative—it works by triggering bowel contractions to relieve constipation. Raspberry fruit powder (the whole fruit) adds additional compounds from raspberries.

The capsule also contains several inactive ingredients: gelatin, microcrystalline cellulose (a filler), rice flour, croscarmellose sodium (a binder), and magnesium stearate (a lubricant).

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: Natural weight loss support.
  • We looked for evidence on: Obesity, Weight management, Metabolic support, Fat reduction.
  • The closest evidence on file: Red Raspberry is rated "Insufficient Reliable Evidence To Rate" for Obesity (Natural Medicines).
  • Also on file: Raspberry Ketone is rated "Insufficient Reliable Evidence To Rate" for Obesity.

The evidence for what this product actually does is thin. Raspberry ketone for weight loss or hair loss (alopecia areata) has insufficient reliable evidence to rate—we don't know if it works.

Cascara sagrada for constipation also has insufficient evidence, and for bowel prep it appears possibly ineffective. Red raspberry fruit has insufficient reliable evidence for aging skin, heart disease, respiratory infections, heart failure, and diabetes.

In short, the data we hold doesn't establish that these ingredients deliver the results the name suggests.

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Raspberry ketone is used in foods safely, but human safety data for high supplement doses is very limited. Oral case reports describe heart palpitations, fast heartbeat, high blood pressure, and in rare cases dangerous heart rhythms.

Some people also report sweating, diarrhea, and shakiness. Cascara sagrada works short-term but carries real risks, especially with long-term use—it can cause mild cramping and abdominal discomfort, and rarely severe vomiting, liver injury, and with prolonged use, loss of muscle tone and kidney problems.

Red raspberry fruit is generally well tolerated by most adults, though diarrhea and stomach upset can occur, and occupational inhalation of the powder has triggered asthma symptoms in at least one worker. Pregnancy and breastfeeding: There isn't enough safety information for raspberry ketone or cascara sagrada during pregnancy—the data advises against both.

Cascara is not recommended while nursing because active compounds may pass into breast milk. Red raspberry safety in pregnancy and lactation isn't well established—talk with your doctor or pharmacist for personalized guidance if you're pregnant or nursing.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 3 of the 3 matched ingredients can interact with medications — Red Raspberry, Cascara Sagrada, Raspberry Ketone.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; heart-rhythm medications.
  • For scale: 929 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 you start, double-check if you take warfarin or any blood thinner—both raspberry ketone and cascara sagrada may interfere. Stimulant drugs and ADHD medications pair poorly with raspberry ketone.

Water pills, steroids, digoxin, or insulin should all be reviewed with your pharmacist. Anticoagulant or antiplatelet drugs also deserve a check because of the red raspberry fruit component.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This product combines a weight-loss ingredient with limited evidence, a laxative with serious long-term risks, and a fruit powder—all three have documented interactions with common medications. If you take warfarin, diuretics, steroids, digoxin, insulin, stimulants, or anticoagulants, you need to check with your pharmacist first.

If you're pregnant or nursing, avoid it. Otherwise, the real question is whether it works—and the data doesn't show it does.

Theoretically, cascara sagrada might increase the risk of hypokalemia when taken with corticosteroids.
Cascara sagrada has stimulant laxative effects, and long-term use has been associated with hypokalemia.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, cascara sagrada might cause hypokalemia, potentially increasing the risk of digoxin toxicity.
Cascara sagrada has stimulant laxative effects, and long-term use has been associated with hypokalemia.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, cascara sagrada might increase the risk of hypokalemia when taken with diuretic drugs.

Likelihood Possible Evidence D
Stimulant Laxatives

Theoretically, cascara sagrada might have additive adverse effects when taken with stimulant laxatives.
Cascara sagrada has stimulant laxative effects and might compound fluid and electrolyte losses when taken with stimulant laxatives.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, cascara sagrada might increase the risk of bleeding when taken with warfarin.
Cascara sagrada has stimulant laxative effects. In some people, cascara sagrada can cause diarrhea. Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, cascara sagrada might decrease the effects of CYP3A4 substrates.
In vitro research suggests that cascara sagrada can induce CYP3A4 enzymes, albeit to a much lower degree than rifampin, a known CYP3A4 inducer.

Likelihood Possible Evidence D

Raspberry Ketone2 drug types · 174 drugs

Stimulant Drugs

Theoretically, raspberry ketone might increase the risk of adverse cardiovascular effects with stimulant drugs.
Structurally, raspberry ketone resembles synephrine, a known stimulant agent. Heart palpitations, elevated blood pressure, coronary vasospasm, pulseless electrical activity arrest, and resistant polymorphic ventricular tachycardia have been reported in patients taking raspberry ketone.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, raspberry ketone might increase warfarin dose requirements.
In one case report, a patient taking warfarin 55 mg per week had a decrease in INR over a period of one month while taking raspberry ketone 250 mg daily. A warfarin dose increase to 70 mg per week was necessary to maintain a therapeutic INR while taking raspberry ketone. The mechanism for this potential interaction is not known.

Likelihood Possible Evidence D

Raspberry fruit powder2 drug types · 135 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, taking red raspberry leaf with anticoagulant/antiplatelet drugs might increase the risk of bleeding.
In vitro research suggests that red raspberry leaf extract has antiplatelet activity and enhances the in vitro effects of the antiplatelet medication cangrelor. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Insulin

Red raspberry leaf might reduce glucose levels in patients being treated with insulin.
In one case report, a 38-year-old patient with gestational diabetes, whose blood glucose was being controlled with medical nutrition therapy and insulin, developed hypoglycemia after consuming two servings of raspberry leaf tea daily for 3 days beginning at 32 weeks' gestation. The patient required an insulin dose reduction. The hypoglycemia was considered to be probably related to use of red raspberry leaf tea.

Ultimate Strength Raspberry Ketone Flush by New Health Corp.: Common Questions

Does Ultimate Strength Raspberry Ketone Flush by New Health Corp. interact with any medications?
Yes. Based on its ingredients, Ultimate Strength Raspberry Ketone Flush has a known interaction with 928 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Ultimate Strength Raspberry Ketone Flush contains 3 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.
Can I take this if I'm on warfarin?
No, not without talking to your doctor first. Raspberry ketone and cascara sagrada both interact with warfarin. Raspberry ketone may reduce warfarin's effectiveness and require a dose increase, while cascara can increase warfarin's effects and raise bleeding risk. Your doctor may need to adjust your dose or monitor you more closely.
Does this actually help with weight loss?
The evidence doesn't establish that it does. Raspberry ketone for weight loss has insufficient reliable evidence to rate, meaning we don't know if it works. The other ingredients are a laxative and fruit powder, neither of which are proven weight-loss agents.
Is it safe to take long-term?
Not safely. Cascara sagrada carries real risks with long-term use—it can cause loss of muscle, kidney problems, and liver injury. Raspberry ketone safety data for high doses is very limited. Short-term use only is the safer choice, and even then, check with your pharmacist about your medications.
What are the side effects I might notice?
Raspberry ketone can cause heart palpitations, fast heartbeat, high blood pressure, sweating, diarrhea, and shakiness. Cascara sagrada typically causes mild cramping and abdominal discomfort, and rarely severe vomiting. Red raspberry may cause diarrhea and stomach upset. If you experience heart symptoms, stop and seek medical help.
Can I take this while pregnant or nursing?
No. There isn't enough safety information for raspberry ketone or cascara sagrada in pregnancy—the data advises against both. Cascara may pass active compounds into breast milk, so it's best avoided while nursing. Red raspberry safety in pregnancy and lactation isn't well established—talk with your doctor if you're considering it.
What does each ingredient actually do?
Raspberry ketone is studied for weight loss and hair loss, but evidence is lacking. Cascara sagrada is a laxative that triggers bowel movements to relieve constipation. Red raspberry fruit powder is included for its compounds, but its benefit here isn't proven. None of the three has solid evidence for the results this product name suggests.
