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 0 of its 16 active ingredients.
  • “Ambrotose Complex” is a proprietary blend — the label gives one combined amount (93 mg) without saying how much of each component you get.
  • “Phyt-Aloe Complex” is a proprietary blend — the label gives one combined amount (907 mg) without saying how much of each component you get.

Phyt Aloe contains 16 ingredients, most of which are plant-based vegetables and botanicals. The active ingredients include garlic, tomato, cabbage, kale, carrot, papaya, cauliflower, onion, Brussels sprout, broccoli, and aloe vera extract—each contributing nutrients and compounds traditionally used in herbal and nutritional preparations.

The product also contains several binding and thickening agents: gum tragacanth (a plant-derived gum), larch arabinogalactan (a soluble fiber), and two proprietary blends called Ambrotose Complex and Phyt-Aloe Complex. There are no inactive fillers or other excipients listed beyond these functional ingredients.

Does it work?

Moderate 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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Acne — rated "Possibly Effective" (Aloe) (Natural Medicines).
  • On file: Atherosclerosis — rated "Possibly Effective" (Garlic) (Natural Medicines).
  • On file: Breast engorgement — rated "Possibly Effective" (Cabbage) (Natural Medicines).
  • On file: Burns — rated "Possibly Effective" (Aloe) (Natural Medicines).
  • On file: Nonalcoholic fatty liver disease (NAFLD) — rated "Possibly Effective" (Garlic) (Natural Medicines).

The data we hold shows insufficient or mixed evidence for most conditions this product might address. Garlic is rated possibly effective for blood pressure, diabetes, atherosclerosis, and some liver conditions.

Aloe vera extract is rated possibly effective for burns, constipation, psoriasis, diabetes, and acne. Onion is rated possibly effective for scarring.

Broccoli is rated possibly effective for colorectal cancer. Most other ingredients—including cabbage, kale, carrot, papaya, tomato, and cauliflower—carry ratings of insufficient evidence for the conditions tested, meaning we don't have enough data to say whether they work for those purposes.

Because this is a multi-ingredient product without a single stated purpose, talk with your doctor or pharmacist about what you're hoping to achieve, so they can advise whether the evidence supports its use for your situation.

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 11 of the 13 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 13 of 13.
  • General safety write-ups exist for 13 of 13.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most of these ingredients are foods eaten regularly and are generally well tolerated at typical food amounts. However, concentrated supplement doses are less studied.

Garlic can cause stomach upset, bad breath, and body odor orally; it also carries a small risk of increased bleeding. Aloe latex (the yellow substance under the leaf skin) can cause serious side effects—abdominal cramps, diarrhea, and electrolyte loss—and should not be taken by mouth long-term or in high doses.

Papaya, particularly unripe fruit and its latex, is best avoided in supplement form. Onion may trigger allergic reactions in sensitive people.

Gum tragacanth can cause asthma-like symptoms in those sensitive to quillaia bark. Larch arabinogalactan may cause bloating and gas in some people.

During pregnancy, aloe latex should be avoided because it may stimulate the uterus and act as a strong laxative; papaya safety data are mixed, so talk with your doctor. While breastfeeding, aloe latex and high-dose supplements of larch arabinogalactan should be avoided.

Why this rating?
  • 10 of the 13 matched ingredients can interact with medications — Cabbage, Garlic, Papaya, Aloe, Onion, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; heart-rhythm medications; lithium.
  • For scale: 2,200 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 Phyt Aloe, check your doctor or pharmacist about these medication types. Most serious: heart medications like digoxin (Lanoxin).

Major Moderate concerns: blood thinners (warfarin, aspirin, clopidogrel), blood pressure medications, diabetes drugs, diuretics (water pills), thyroid medication (levothyroxine), and drugs processed by your liver's cytochrome P450 system. Also check if you take cardiac rhythm drugs (amiodarone), immunosuppressants, anxiety or seizure medications, pain relievers (acetaminophen), or protease inhibitors (HIV drugs).

No interactions are documented for the ingredients we could check if you don't fall into one of these categories—but that's not a guarantee none exist.

Gum Tragacanth1 drug type · 2,022 drugs

Oral Drugs

Theoretically, tragacanth might alter absorption of oral drugs.
Tragacanth contains hydrocolloidal fiber which can decrease, increase, or not affect oral drug absorption. To avoid changes in absorption, take tragacanth 30-60 minutes after oral medications.

Likelihood Possible Evidence D
Gum Tragacanth full monograph & interactions

Garlic12 drug types · 989 drugs

Anticoagulant/Antiplatelet Drugs

Garlic may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Raw garlic and a variety of garlic extracts have antiplatelet activity and can increase prothrombin time.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, taking garlic with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research suggests that garlic and garlic extract lower blood glucose levels in healthy and diabetic individuals.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, taking garlic with antihypertensive drugs might increase the risk of hypotension.
In human research, both garlic and garlic extracts have blood pressure-lowering effects.

Likelihood Possible Evidence D
Atazanavir (Reyataz)

Theoretically, garlic might decrease levels and effects of atazanavir.
In a case report, a patient consuming six stir-fried garlic cloves three times weekly developed suboptimal atazanavir levels and increases in HIV viral load. While the exact cause of this interaction is unclear, there is speculation that garlic might decrease the intestinal absorption of atazanavir or increase its metabolism by inducing cytochrome P450 3A4 (CYP3A4). Until more is known, advise patients not to consume large amounts of garlic while taking atazanavir.

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Garlic might increase levels of drugs metabolized by CYP2E1.
Clinical research suggests garlic oil can inhibit the activity of CYP2E1 by 39%. Use garlic oil cautiously in patients taking drugs metabolized by these enzymes.

Likelihood Probable Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, garlic products containing allicin might induce intestinal CYP3A4 and inhibit hepatic CYP3A4. This may increase or decrease levels of drugs metabolized by CYP3A4.
Some human research suggests that garlic may induce INTESTINAL CYP3A4, reducing levels of drugs metabolized by this enzyme. This is primarily based on a study showing that taking a specific allicin-containing garlic product (GarliPure Maximum Allicin Formula, Natrol Inc.) twice daily for 3 days reduces saquinavir levels by approximately 50%. It is speculated that the allicin constituent induced CYP3A4 in the gut mucosa. Another study shows that giving docetaxel intravenously, bypassing the CYP3A4 enzymes in the gut mucosa, along with the same specific garlic product for 12 consecutive days, does not affect docetaxel levels. Conversely, there is concern that garlic may inhibit HEPATIC CYP3A4. In a single case report, increased tacrolimus levels and liver injury occurred in a liver transplant patient after taking a specific garlic supplement (Garlicin Cardio, Nature's Way) at up to three times the manufacturer recommended dose for 7 days. Several other studies have evaluated the impact of other garlic formulations on CYP3A4 substrates and have found no effect. Most of the products in these studies provided little or no allicin.

Likelihood Possible Evidence B
Isoniazid

Theoretically, garlic might decrease levels of isoniazid.
Animal research suggests that an aqueous extract of garlic reduces isoniazid levels by about 65%. Garlic reduced the maximum concentration (Cmax) and area under the curve (AUC), but not the half-life, of isoniazid. This suggests that garlic extract might inhibit isoniazid absorption across the intestinal mucosa; however, the exact mechanism of this potential interaction is not known.

Likelihood Possible Evidence D
Protease Inhibitors (Pis)

Theoretically, garlic products containing allicin might decrease levels of PIs.
Protease inhibitors are metabolized by cytochrome P450 3A4 (CYP3A4) isoenzymes. There is concern that garlic products containing allicin might induce intestinal CYP3A4, reducing plasma levels of protease inhibitors. This is primarily based on a study showing that taking a specific garlic product (GarliPure Maximum Allicin Formula, Natrol Inc.) twice daily for 3 days reduces levels of saquinavir, a PI, by approximately 50%. It is speculated that the allicin constituent induce CYP3A4 in the gut mucosa. Several studies have evaluated the impact of other garlic formulations on CYP3A4 substrates and have found no effect. Most of the products in these studies provided little or no allicin.

Likelihood Possible Evidence B
Saquinavir (Fortovase, Invirase)

Theoretically, garlic containing allicin might decrease levels of saquinavir.
Saquinavir is a substrate of cytochrome P450 3A4 (CYP3A4) isoenzymes. There is concern that garlic products containing allicin might induce intestinal CYP3A4 and cause subtherapeutic levels of saquinavir. This is primarily based on a pharmacokinetic study showing that taking a specific garlic product (GarliPure Maximum Allicin Formula, Natrol Inc.) twice daily for 3 days reduces saquinavir levels by approximately 50%. It is speculated that the allicin constituent induces CYP3A4 in the gut mucosa. Several pharmacokinetic studies have evaluated the impact of other garlic formulations on CYP3A4 substrates and have found no effect. Most of the products in these studies provided little or no allicin. Until more is known about this potential interaction, use garlic containing allicin cautiously in patients taking saquinavir.

Likelihood Possible Evidence B
Sofosbuvir (Sovaldi)

Theoretically, taking garlic with sofosbuvir might decrease its effectiveness.
Animal research in rats shows that giving aged garlic extract 120 mg/kg orally daily for 14 days decreases the area under the concentration time curve (AUC) after a single sofosbuvir dose of 40 mg/kg by 36%, increases the clearance by 63%, and decreases the plasma concentrations at 1 and 8 hours by 35% and 58%, respectively. This interaction is hypothesized to be due to induction of intestinal P-glycoprotein expression by garlic.

Likelihood Possible Evidence D
Tacrolimus (Prograf)

Theoretically, garlic might increase levels of tacrolimus.
In one case report, a liver transplant patient taking tacrolimus experienced increased tacrolimus levels and liver injury after taking a specific garlic supplement (Garlicin Cardio, Nature's Way) at up to three times the manufacturer recommended dose for 7 days. It is speculated that garlic inhibited hepatic cytochrome P450 3A4 (CYP3A4), which increased plasma levels of tacrolimus.

Likelihood Possible Evidence B
Warfarin (Coumadin)

Theoretically, garlic might increase the risk of bleeding with warfarin.
Raw garlic and a variety of garlic extracts have antiplatelet activity and can increase prothrombin time. In addition, there is a report of two patients who experienced an increase in a previously stabilized international normalized ratio (INR) with concomitant garlic and warfarin use. However, this report has been subsequently debated due to limited clinical information. Other clinical studies have not identified an effect of garlic on INR, warfarin pharmacokinetics, or bleeding risk. More evidence is needed to determine the safety of using garlic with warfarin.

Likelihood Possible Evidence D
Garlic full monograph & interactions

Aloe vera extract7 drug types · 461 drugs

Digoxin (Lanoxin)

Theoretically, aloe latex might increase the risk of adverse effects when taken with cardiac glycosides.
Overuse of aloe latex can increase the risk of adverse effects from cardiac glycoside drugs, such as digoxin, due to potassium depletion. Overuse of aloe, along with cardiac glycoside drugs, can increase the risk of toxicity.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, aloe gel might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro research shows that aloe gel can inhibit platelet aggregation. This inhibition was greater than that seen with celecoxib, but less than that seen with aspirin.

Likelihood Possible Evidence D
Antidiabetes Drugs

Aloe might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Preliminary clinical research suggests aloe gel might lower blood glucose levels and have additive effects when used with antidiabetes drugs. Monitor blood glucose levels closely.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, aloe latex might increase the risk of hypokalemia when taken with diuretic drugs.
Overuse of aloe latex might compound diuretic-induced potassium loss, increasing the risk of hypokalemia.

Likelihood Possible Evidence D
Stimulant Laxatives

Theoretically, aloe latex might increase the risk for fluid and electrolyte loss when taken with stimulant laxatives.
Due to cathartic laxative effects of aloe latex, concomitant use with other stimulant laxatives might compound fluid and electrolyte loss.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, aloe latex might increase the risk of bleeding when taken with warfarin.
Aloe latex has stimulant laxative effects. In some people aloe latex can cause diarrhea. Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding. Advise patients who take warfarin not to take excessive amounts of aloe vera.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, aloe might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that aloe extract induces CYP1A2 enzymes.

Likelihood Possible Evidence D
Aloe vera extract full monograph & interactions

Cabbage6 drug types · 325 drugs

Acetaminophen (Tylenol, Others)

Cabbage might increase clearance and reduce the effects of acetaminophen.
A small clinical study shows that daily consumption of cabbage and Brussels sprout decreases acetaminophen levels by as much as 16%, with some evidence suggesting that this effect is due to increased elimination through glucuronide conjugation.

Likelihood Probable Evidence B
Antidiabetes Drugs

Theoretically, cabbage might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal and in vivo research suggests that cabbage might have hypoglycemic effects.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, cabbage might decrease levels of drugs metabolized by CYP1A2.
Some animal research suggests that cabbage or its constituent indole-3-carbinol might increase drug metabolism and elimination by stimulating CYP1A2 activity.

Likelihood Possible Evidence D
Glucuronidated Drugs

Theoretically, cabbage might increase clearance and decrease the effects of drugs metabolized through glucuronide conjugation.
A small clinical study shows that daily consumption of cabbage and Brussels sprout decreases levels of some drugs metabolized through glucuronide conjugation.

Likelihood Probable Evidence B
Oxazepam (Serax)

Cabbage might increase clearance and reduce the effects of oxazepam.
A small clinical study shows that daily consumption of cabbage and brussels sprout decreases oxazepam levels by as much as 17%, with some evidence suggesting that this effect is due to increased elimination through glucuronide conjugation.

Likelihood Probable Evidence B
Warfarin (Coumadin)

Theoretically, cabbage might decrease the anticoagulant effects of warfarin.
Cabbage contains vitamin K. If consumed in large quantities, cabbage might decrease the anticoagulant effects of warfarin.

Likelihood Possible Evidence D
Cabbage full monograph & interactions

Onion5 drug types · 275 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, concomitant use of anticoagulant or antiplatelet drugs with onion might increase the risk of bleeding.
In vitro research shows that onion inhibits platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Concomitant use of antidiabetes drugs with onion may increase the risk of hypoglycemia.
Animal research and clinical research shows that taking onion can lower blood glucose levels. Monitor blood glucose levels closely.

Likelihood Possible Evidence B
Aspirin

Concomitant use of aspirin with onion may worsen onion allergy.
In one case report, a patient with a mild onion allergy reported worsening allergy, including swelling and severe urticaria, after taking aspirin.

Likelihood Probable Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Animal research shows that taking onion powder inhibits CYP2E1. However, this interaction has not been reported in humans.

Likelihood Possible Evidence B
Lithium

Onion is thought to have diuretic properties. Theoretically, due to these potential diuretic effects, onion might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Likelihood Probable Evidence D
Onion full monograph & interactions

Brussels Sprout5 drug types · 241 drugs

Acetaminophen (Tylenol, Others)

A cabbage and Brussels sprout-containing diet can increase metabolism and decrease levels of acetaminophen. In clinical research, a diet that includes daily consumption of cabbage and Brussels sprout decreases acetaminophen levels by as much as 16%. This appears to occur due to a boost of elimination through glucuronide conjugation.

Likelihood Probable Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Animal research suggests that Brussels sprout can induce cytochrome P450 1A2 (CYP1A2) activity. Theoretically, Brussels sprout might increase the clearance and decrease the effects of drugs metabolized by CYP1A2. Some drugs metabolized by CYP1A2 include clozapine (Clozaril), cyclobenzaprine (Flexeril), fluvoxamine (Luvox), haloperidol (Haldol), imipramine (Tofranil), mexiletine (Mexitil), olanzapine (Zyprexa), pentazocine (Talwin), propranolol (Inderal), tacrine (Cognex), theophylline, zileuton (Zyflo), zolmitriptan (Zomig), and others.

Likelihood Possible Evidence D
Glucuronidated Drugs

Arabinogalactan1 drug type · 121 drugs

Immunosuppressants

Theoretically, larch arabinogalactan might interfere with immunosuppression therapy due to immunostimulant effects. Immunosuppressant drugs include azathioprine (Imuran), basiliximab (Simulect), cyclosporine (Neoral, Sandimmune), daclizumab (Zenapax), muromonab-CD3 (OKT3, Orthoclone OKT3), mycophenolate (CellCept), tacrolimus (FK506, Prograf), sirolimus (Rapamune), prednisone (Deltasone, Orasone), corticosteroids (glucocorticoids), and other drugs.

Likelihood Possible Evidence D
Arabinogalactan full monograph & interactions

Papaya4 drug types · 92 drugs

Amiodarone (Cordarone)

Theoretically, papaya extract may increase the levels and clinical effects of amiodarone.
Animal research in rats shows that a single oral dose of papaya extract, as well as multiple doses of papaya extract daily over 14 days, prior to a single dose of amiodarone delays the time to maximum amiodarone concentration. However, only the 14-day papaya extract regimen increases systemic amiodarone exposure by 60% to 70%. This interaction has not been reported in humans.

Likelihood Probable Evidence D
Antidiabetes Drugs

Concomitant use of antidiabetic drugs with fermented papaya can produce additive effects. It is unclear if other forms of papaya have the same effect.
A small low-quality clinical study in patients with type 2 diabetes who are taking glibenclamide shows that taking a fermented papaya preparation 3 grams daily for 2 months decreases fasting and postprandial blood glucose levels when compared to baseline. Additionally, of the 25 patients in the study, 9 required a reduction in glibenclamide dose.

Likelihood Probable Evidence B
Levothyroxine (Synthroid, Others)

Theoretically, consuming large quantities of papaya fruit can reduce the clinical effects of levothyroxine.
In one case-report, a 37-year-old male with a history of thyroidectomy who was stabilized on levothyroxine for 5 years presented with hypothyroidism after consuming 5-6 papaya fruits daily for 14 days during vacation. In a controlled re-challenge test involving 5-6 papayas daily, the patient remained euthyroid for 7 days, but developed mild hypothyroidism after 14 days. Both times, thyroid levels normalized 40-45 days after discontinuing papaya.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, concomitant use of warfarin with papain-containing papaya extract might increase the effects and side effects of warfarin.
In one case report, a patient previously stable on warfarin was found to have an international normalization ratio (INR) of 7.4, which was attributed to ingestion of a supplement containing papain from papaya extract.

Phyt Aloe by Mannatech: Common Questions

Does Phyt Aloe by Mannatech interact with any medications?
Yes. Based on its ingredients, Phyt Aloe has a known interaction with 2,199 medications, including 1 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Phyt Aloe contains 16 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.
What's aloe vera extract doing in a powder I'm supposed to swallow?
Aloe vera extract in this powder is aloe gel, not aloe latex. Gel is generally well tolerated when taken by mouth in reasonable doses and is rated possibly effective for several conditions including burns, constipation, and diabetes. Aloe latex—the yellow substance under the leaf—is the form linked to serious side effects and should be avoided by mouth long-term or in high doses.
Can I take this if I'm on warfarin?
No. Phyt Aloe contains cabbage, Brussels sprout, broccoli, papaya, garlic, and onion—ingredients with documented Moderate interactions with warfarin. Some may decrease warfarin's blood-thinning effect, while others may increase it. You must talk with your doctor or pharmacist before taking this product if you're on warfarin or any blood thinner.
Will this help my diabetes?
Garlic and aloe vera extract in this product are each rated possibly effective for diabetes, based on preliminary research showing they may help lower blood sugar. However, if you take diabetes medication, this product could increase your blood-sugar-lowering effect too much. Talk with your doctor before adding it—don't start on your own.
Is this safe during pregnancy?
No, not without checking with your doctor first. The aloe vera extract in this powder should be avoided during pregnancy because aloe latex can stimulate the uterus and act as a strong laxative. Papaya's safety data during pregnancy are also mixed. Talk with your doctor or pharmacist before using this product if you're pregnant.
What if I'm allergic to cruciferous vegetables like broccoli?
This product contains broccoli, Brussels sprout, cabbage, and cauliflower—all cruciferous vegetables. If you're allergic to any of these, you should avoid this powder. In people with Brassicaceae allergies, anaphylactic reactions, though rare, have been reported.
Does this have any fillers or additives?
No fillers or additives are listed beyond the active plant ingredients and two proprietary blends (Ambrotose Complex and Phyt-Aloe Complex). The thickeners are gum tragacanth and larch arabinogalactan, both plant-derived.
