HelloPharmacist Scorecard of PLUS by Mannatech
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
Partial disclosure
Mannatech PLUS contains 11 active ingredients: glycine, L-glutamic acid, L-arginine, L-lysine, ghatti gum, gum tragacanth, arabinogalactan (larch arabinogalactan), wild yam extract, aloe vera, ambrotose complex, beta-sitosterol (standardized to 12.5% diosgenin), and boron. Glycine and L-arginine are amino acids; L-lysine is another amino acid used for herpes support.
Aloe vera, wild yam extract, and the arabinogalactan and ambrotose complex are botanical or polysaccharide ingredients. Beta-sitosterol is a plant-derived sterol, and boron is a mineral trace element.
The gums (ghatti and tragacanth) and arabinogalactan act as thickening or fiber agents. The product also contains several inactive ingredients—microcrystalline cellulose, stearic acid, croscarmellose sodium, silicon dioxide, hypromellose, calcium carbonate, medium chain triglycerides, magnesium stearate, and xylitol—which are fillers, binders, and capsule components.
Does it work?
Strong evidence
The evidence for PLUS's ingredients is mixed. Aloe vera is possibly effective for acne, obesity, diabetes, psoriasis, burns, and constipation.
Beta-sitosterol is likely effective for benign prostatic hyperplasia (enlarged prostate) and possibly effective for familial high cholesterol and coronary heart disease. Boron is likely effective for boron deficiency and possibly effective for vaginal yeast infections and radiation skin damage.
Glycine is possibly effective for schizophrenia. L-lysine is possibly effective for cold sores.
For most other uses—including L-arginine, L-glutamic acid, ghatti gum, gum tragacanth, and arabinogalactan—the evidence we hold is insufficient to establish effectiveness, or the data show these ingredients may not work for their proposed use (boron for athletic performance, for example, is possibly ineffective).
How safe is it?
Well-documented data
Most of these ingredients are generally well tolerated at typical doses, though some carry important cautions. Glycine may rarely cause mild sedation, irritability, insomnia, fatigue, memory impairment, headache, or sensory changes; digestive upset and dry mouth have also been reported.
L-arginine is often well tolerated short-term but can lower blood pressure and should be used only under medical supervision. L-lysine is generally well tolerated but at high amounts may cause stomach upset; long-term safety is not well studied.
Gum tragacanth is recognized as safe in food amounts but can trigger asthma symptoms in people sensitive to quillaia bark. Arabinogalactan may cause bloating and gas.
Aloe vera's topical gel is generally well tolerated, but oral aloe latex can cause abdominal pain, cramps, and diarrhea; long-term or excessive use raises the risk of serious effects including severe potassium loss, muscle weakness, and heart rhythm problems. Pregnancy and breastfeeding data are not well established for most ingredients here — glycine, L-arginine, L-lysine, gum tragacanth, and arabinogalactan all lack adequate safety information in pregnancy and lactation.
Aloe latex is possibly unsafe in both pregnancy (may stimulate the uterus and cause strong laxative effects) and breastfeeding. Beta-sitosterol and boron should be avoided in pregnancy and lactation.
Boron in high doses can be toxic.
Meds to double-check
Major interaction found
Before taking PLUS, double-check with your own doctor or pharmacist if you take digoxin (the most serious concern, Major-severity risk), any blood pressure medications including ACE inhibitors or ARBs, blood thinners such as warfarin or antiplatelet drugs, diabetes medications, potassium-sparing diuretics, stimulant laxatives, clozapine, isoproterenol, sildenafil, or drugs metabolized by CYP1A2 enzymes. Also remember to space any other oral medications 30–60 minutes away from this product to avoid changes in how your body absorbs them.
The bottom line
Scorecard at a glancePartially disclosed formula with strong clinical evidence behind its ingredients' uses. Major medication interactions have been identified, and safety information is well characterized.
PLUS may be of interest to people seeking support for herpes, prostate health, cholesterol, or the specific uses covered by its individual ingredients—but its interaction profile is complex. If you take digoxin, blood pressure medication, blood thinners, diabetes medication, diuretics, clozapine, or any CYP1A2 substrate drugs, you need to review this product with your own doctor or pharmacist before starting.
Pregnant or breastfeeding women should also check with their healthcare provider first, since safety data for most ingredients are limited or not established. The same applies if you have asthma or are sensitive to quillaia bark.

PLUS by Mannatech Drug Interactions
HelloPharmacist Interaction Report
Mannatech PLUS contains several ingredients with documented interactions with medications.
The most serious concern is aloe vera, which carries a Major-severity interaction with digoxin (Lanoxin), a heart medication — overuse of aloe latex can deplete potassium and increase the risk of digoxin toxicity. Additionally, through its L-arginine, L-lysine, aloe vera, and gum tragacanth content, this product interacts with multiple drug types at Moderate severity.
Read the full breakdown — every affected drug type, severity by severity
L-arginine may lower blood pressure when combined with antihypertensive drugs, ACE inhibitors, ARBs, or isoproterenol, and it can raise potassium levels when used with potassium-sparing diuretics or ACE inhibitors and ARBs. It may also have additive effects with blood thinners (anticoagulant and antiplatelet drugs) and diabetes medications.
Aloe vera similarly interacts with blood thinners and diabetes drugs, and can increase potassium loss when taken with diuretics or stimulant laxatives, or increase the risk of bleeding with warfarin. Gum tragacanth can alter how your body absorbs oral medications — space it 30–60 minutes away from your other drugs.
Glycine carries a Moderate interaction with clozapine (Clozaril) and may worsen schizophrenia symptoms in people taking that antipsychotic.
L-lysine has one Minor-severity interaction with 5-HT4 agonist drugs. Aloe vera also has a Minor interaction with CYP1A2 substrates, a group of medications metabolized by your liver.
We could not check L-glutamic acid, ghatti gum, wild yam extract, or the standardized diosgenin component — no interaction data are on file for them.
Alogether, these interactions span 2,154 individual medications. Use the medication checker on this page to see whether any of your prescriptions or over-the-counter drugs are affected before you start PLUS.

For each ingredient in PLUS 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.
Gum Tragacanth
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.
Aloe vera
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.
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.
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.
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.
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.
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.
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.
L-Arginine
Ace Inhibitors (Aceis)
Theoretically, concomitant use of L-arginine and ACE inhibitors may increase the risk for hypotension and hyperkalemia.
Combining L-arginine with some antihypertensive drugs, especially ACE inhibitors, seems to have additive vasodilating and blood pressure-lowering effects. Furthermore, ACE inhibitors can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients. Theoretically, concomitant use of ACE inhibitors with L-arginine may increases the risk of hyperkalemia.
Angiotensin Receptor Blockers (Arbs)
Theoretically, concomitant use of L-arginine and ARBs may increase the risk of hypotension and hyperkalemia.
L-arginine increases nitric oxide, which causes vasodilation. Combining L-arginine with ARBs seems to increase L-arginine-induced vasodilation. Furthermore, ARBs can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients. Theoretically, concomitant use of ARBs with L-arginine may increases the risk of hyperkalemia.
Anticoagulant/Antiplatelet Drugs
Theoretically, concomitant use of L-arginine with anticoagulant and antiplatelet drugs might have additive effects and increase the risk of bleeding.
Preliminary research suggests that L-arginine infusions reduce platelet aggregation in humans. The clinical significance of this effect is unclear.
Antidiabetes Drugs
Theoretically, concomitant use of L-arginine might have additive effects with antidiabetes drugs.
Preliminary clinical research shows that L-arginine decreases blood glucose levels in patients with type 2 diabetes.
Antihypertensive Drugs
Theoretically, concomitant use of L-arginine and antihypertensive drugs may increase the risk of hypotension.
L-arginine increases nitric oxide, which causes vasodilation. Clinical evidence shows that L-arginine can reduce blood pressure in some individuals with hypertension. Furthermore, combining L-arginine with some antihypertensive drugs seems to have additive vasodilating and blood pressure-lowering effects.
Isoproterenol (Isuprel)
Theoretically, concurrent use of isoproterenol and L-arginine might result in additive effects and hypotension.
Preliminary clinical evidence suggests that L-arginine enhances isoproterenol-induced vasodilation in patients with essential hypertension or a family history of essential hypertension.
Potassium-Sparing Diuretics
Theoretically concomitant use of potassium-sparing diuretics with L-arginine may increases the risk of hyperkalemia.
Potassium-sparing diuretics can increase potassium levels. Use of L-arginine has been associated with hyperkalemia in some patients.
Sildenafil (Viagra)
Theoretically, concurrent use of sildenafil and L-arginine might increase the risk for hypotension.
In vivo, concurrent use of L-arginine and sildenafil has resulted in increased vasodilation. Theoretically, concurrent use might have additive vasodilatory and hypotensive effects. However, in studies evaluating the combined use of L-arginine and sildenafil for erectile dysfunction, hypotension was not reported.
Testosterone
Theoretically, concomitant use of L-arginine and testosterone might have additive effects.
In clinical research, L-arginine increases the level of testosterone in male patients with erectile dysfunction. The clinical significance of this finding is unclear.
Arabinogalactan
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.
Wild Yam extract
Estrogens
Theoretically, wild yam might increase or decrease the effects of estrogen.
Wild yam root shows estrogenic and anti-estrogenic effects in vitro. Theoretically, wild yam might interfere with hormone therapy.
Glycine
Clozapine (Clozaril)
Theoretically, glycine might decrease the effectiveness of clozapine.
One small clinical study in patients with schizophrenia shows that adding glycine to clozapine therapy worsens symptoms of schizophrenia when compared with clozapine alone. The mechanism of this interaction is unclear.
L-Lysine
5-Ht4 Agonists
Theoretically, lysine may reduce the effects of 5-HT4 agonists.
Animal research suggests that L-lysine is a partial serotonin receptor 4 (5-HT4) antagonist and inhibits diarrhea induced by the 5-HT4 agonist, 5-hydroxytryptophane.
