HelloPharmacist Scorecard of Non-GMO Soy Isoflavones by Puritan's Pride
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
Low disclosure
This product contains 4 active ingredients, all isoflavones — compounds found naturally in soy. The main one we have data for is isoflavones from kudzu.
The other three ingredients (daidzin and daidzein, glycitin and glycitein, and genistin and genistein) are additional isoflavone compounds that make up the soy germ concentrate. The only inactive ingredient listed is gelatin, which forms the capsule.
Does it work?
Moderate evidence
For alcohol use disorder, kudzu isoflavones are rated possibly effective — the evidence suggests there may be some benefit, but it's not definitive. For allergic rhinitis (hay fever), angina, and back pain, there isn't enough reliable evidence to say whether this product works or not.
If you're considering it for one of those conditions, talk with your pharmacist or doctor about what the research actually shows and whether it makes sense for you.
How safe is it?
Well-documented data
In short-term studies, kudzu isoflavones are generally well tolerated. Some people reported nausea, stomach upset, bloating, dizziness, or rash in clinical trials, but these showed up at the same rate as placebo — meaning they weren't clearly caused by the supplement.
Long-term safety hasn't been well studied, so we don't know what happens if you take it for months or years. Don't use this product if you're pregnant — there isn't enough safety data and the hormone-like effects are a concern.
The same goes for breastfeeding: there's too little information to recommend it. If you're thinking about it during either phase, talk with your doctor or pharmacist about your individual situation.
Meds to double-check
Moderate interaction found
Before you take this product, double-check with your pharmacist if you're on blood thinners or antiplatelet drugs like warfarin or aspirin (Moderate severity), estrogen therapy or tamoxifen (Moderate), drugs that stress the liver, methotrexate, caffeine supplements or high-dose caffeine products, or diabetes medications (Minor). No interactions are documented for the three other isoflavone ingredients we couldn't check, but that doesn't mean they don't exist.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
This product is mainly of interest for alcohol use disorder, where there's some evidence it may help. If you take any blood thinners, hormone therapies, diabetes medications, methotrexate, or caffeine regularly, you need to check your specific drugs before starting — the interaction risks are real.
Talk with your pharmacist first, especially if you're on multiple medications or have liver concerns.

Non-GMO Soy Isoflavones by Puritan's Pride Drug Interactions
HelloPharmacist Interaction Report
Puritan's Pride Non-GMO Soy Isoflavones contains isoflavones from kudzu, which has documented interactions with medications.
The most serious concern is with blood thinners and antiplatelet drugs (like warfarin or aspirin) — kudzu isoflavones may increase bleeding risk by thinning the blood further.
Read the full breakdown — every affected drug type, severity by severity
You'll also want to check if you take hormone therapies like estrogen or tamoxifen. Kudzu may have estrogenic effects of its own, which could enhance or reduce how these medications work.
Similarly, liver-toxic drugs (ones that can stress your liver) might have additive harmful effects when combined with kudzu. There's also a theoretical risk with methotrexate — kudzu might slow its elimination and raise toxicity risk — and with diabetes medications, which could theoretically increase low blood sugar (hypoglycemia) risk.
Caffeine is another one to watch: kudzu may slow how your body clears it, potentially raising caffeine levels in your system. We could not check three other ingredients in this product: daidzin and daidzein, glycitin and glycitein, and genistin and genistein.
Altogether, these interactions span 585 individual medications. Please check your exact medications with the tool on this page before you start.

For each ingredient in Non-GMO Soy Isoflavones 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.
Soy Germ Isoflavones Concentrate
Monoamine Oxidase Inhibitors (Maois)
Taking soy products containing high amounts of tyramine along with MAOIs can increase the risk of hypertensive crisis.
Fermented soy products such as tofu and soy sauce contain tyramine, a naturally occurring chemical that affects blood pressure regulation. The metabolism of tyramine is decreased by MAOIs. Consuming more than 6 mg of tyramine while taking an MAOI can increase the risk of hypertensive crisis. The amount of tyramine in fermented soy products is usually less than 0.6 mg per serving; however, there can be significant variation depending on the specific product used, storage conditions, and length of storage. Storing one brand of tofu for a week can increase tyramine content from 0.23 mg to 4.8 mg per serving. Advise patients taking MAOIs to avoid fermented soy products that contain high amounts of tyramine.
Antidiabetes Drugs
Soy can lower blood glucose and have additive effects with antidiabetes drugs.
Clinical research shows that whole soy diets and soy-based meals reduce fasting glucose levels in diabetic and non-diabetic individuals. Also, individuals following a soy-based meal replacement plan seem to require lower doses of sulfonylureas and metformin to manage blood glucose levels when compared with individuals following a diet plan recommended by the American Diabetes Association.
Antihypertensive Drugs
Theoretically soy protein may have additive effects with antihypertensive drugs and increase the risk of hypotension.
Although some contradictory research exists, most clinical evidence suggests that consuming soy protein modestly reduces systolic and diastolic blood pressure in individuals with prehypertension or hypertension.
Caffeine
Theoretically, soy might reduce the clearance of caffeine.
Soy contains genistein. Taking genistein 1 gram daily for 14 days seems to inhibit caffeine clearance and metabolism in healthy females. This effect has been attributed to inhibition of the cytochrome P450 1A2 (CYP1A2) enzyme, which is involved in caffeine metabolism. It is unclear if this effect occurs with the lower amounts of genistein found in soy.
Diuretic Drugs
Theoretically, soy might have additive effects when used with diuretic drugs.
Animal research suggests that genistein, a soy isoflavone, increases diuresis within 6 hours of subcutaneous administration in rats. The effects seem to be similar to those of furosemide. This effect has not been reported in humans.
Estrogens
Theoretically, soy might competitively inhibit the effects of estrogen replacement therapy.
Soy contains phytoestrogens and has been shown to have estrogenic activity in some patients. Although this has not been demonstrated in humans, theoretically, concomitant use of soy with estrogen replacement therapy might reduce the effects of the estrogen replacement therapy.
Levothyroxine (Synthroid, Others)
Soy products might reduce the absorption of levothyroxine in some patients.
Preliminary clinical research and a case report suggest that soy-based formulas inhibit the absorption of levothyroxine in infants with congenital hypothyroidism. A levothyroxine dosage increase may be needed for infants with congenital hypothyroidism while using soy-based formulas, and the dose may need to be reduced when soy-based formulas are no longer administered. However, in postmenopausal adults, clinical research shows that taking a single dose of soy extract containing isoflavones 60 mg along with levothyroxine does not affect the oral bioavailability of levothyroxine.
Progesterone
Theoretically, combining soy isoflavones with transdermal progesterone may worsen bone density.
Clinical research suggests that significant bone loss may occur in females with osteoporosis who receive a combination of transdermal progesterone with soy milk containing isoflavones when compared with placebo, soy milk alone, or progesterone alone.
Tamoxifen (Nolvadex)
Theoretically, estrogenic soy isoflavones might alter the effects of tamoxifen.
Laboratory research suggests that genistein and daidzen, isoflavones from soy, can antagonize the antitumor effects of tamoxifen under some circumstances; however, soy isoflavones might have different effects when used at different doses. A relatively low in vitro concentration of soy isoflavones such as 1 microM/L seems to interfere with tamoxifen, whereas high in vitro concentrations such as those >10 microM/L might actually enhance tamoxifen effects. People on a high-soy diet have soy isoflavones levels ranging from 0.1-6 microM/L. Until more is known, advise patients taking tamoxifen to avoid therapeutic use of soy products.
Warfarin (Coumadin)
Theoretically, soy might interfere with the effects of warfarin.
Soy milk has been reported to decrease the international normalized ratio (INR) in a patient taking warfarin. The mechanism of this interaction is not known. However, animal and in vitro research suggests that soy may also inhibit platelet aggregation. Dosing adjustments for warfarin may be necessary.
Antibiotic Drugs
Theoretically, antibiotics may decrease the activity of soy isoflavones.
Intestinal bacteria are responsible in part for converting soy isoflavones into their active forms. Antibiotics may decrease the amount of intestinal bacteria and decrease its ability to convert isoflavones.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Soy might modestly induce CYP2C9 enzymes. However, this effect does not seem to be clinically significant.
In vitro research suggests that an unhydrolyzed soy extract might induce CYP2C9. However, the significance of this interaction is likely minimal. In healthy females taking a specific extract of soy (Genistein Soy Complex, Source Naturals), blood levels of losartan, a CYP2C9 substrate, were not significantly affected.
