HelloPharmacist Scorecard of Digestive Bitters Tonic by Nature's Sunshine
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
Digestive Bitters Tonic contains 10 ingredients total, including a proprietary blend alongside individual components: potassium sorbate (a form of potassium used as a preservative), water, glycerin, dandelion, stevia, gentian, cardamom seed tincture, raspberry syrup, and orange peel tincture. We cannot check phosphoric acid or raspberry syrup for interactions because we hold no data on them.
Glycerin and cardamom are included in food amounts here and are generally well tolerated. The gentian, dandelion, and bitter orange (in the orange peel tincture) are traditional digestive bitter herbs that stimulate digestive secretions, though the clinical evidence for many of their claimed digestive uses is insufficient.
The potassium sorbate serves as a preservative rather than a therapeutic ingredient.
Does it work?
Strong evidence
The clinical evidence for the digestive uses of the main herbal ingredients in this product is not established in our data. Dandelion, gentian, and cardamom all show insufficient reliable evidence to rate for their traditional digestive and wound-healing uses.
Glycerin is rated likely effective for constipation, but this product is marketed as a digestive tonic rather than a constipation remedy. Orange peel tincture (bitter orange) also lacks sufficient evidence to support its claimed uses.
Without established effectiveness for its marketed purpose, this product is best thought of as a traditional remedy rather than one backed by strong clinical data.
How safe is it?
Well-documented data
Potassium sorbate is generally safe from normal food intake, but supplement doses can cause dangerously high blood potassium levels in some people, especially those with kidney disease — use supplements only under medical guidance. Glycerin is generally well tolerated orally in normal amounts, though large doses can cause stomach upset and dehydration concerns.
Dandelion is generally well tolerated as food but is less studied at supplement doses; rare cases of anaphylaxis have been reported in sensitive individuals, and it may cause allergic reactions in people sensitive to the ragweed family. Stevia is generally recognized as safe in typical food amounts, though whole-leaf or high-dose supplements lack safety data.
Gentian is generally tolerated in small amounts but can upset the stomach; safety data at high doses is limited. Orange peel tincture contains stimulant compounds (synephrine and octopamine) that can raise blood pressure and heart rate, especially when combined with caffeine or other stimulants; serious cardiovascular events including heart attack, stroke, and abnormal heartbeats have been reported in rare cases.
For pregnancy: safety data on dandelion, stevia, and gentian during pregnancy is insufficient — talk with your doctor before use. Gentian is traditionally advised against in pregnancy due to lack of safety data.
Orange peel tincture is possibly unsafe in pregnancy due to its stimulant effects. Cardamom is likely safe while breastfeeding, but dandelion and orange peel tincture lack sufficient safety information for breastfeeding — check with your doctor or pharmacist first.
Meds to double-check
Major interaction found
Before taking this product, double-check with your doctor or pharmacist if you take any monoamine oxidase inhibitors (MAOIs — older antidepressants), midazolam (Versed), blood pressure medications (including ACE inhibitors and ARBs), blood thinners or antiplatelet drugs, diabetes medications, lithium, quinolone antibiotics, heart rhythm drugs that prolong the QT interval, stimulant drugs, dextromethorphan (cough syrup), caffeine supplements, or medications processed by the liver through the CYP1A2 or CYP3A4 pathways. The most serious concerns are MAOIs and midazolam, both Major-severity interactions, followed by the Moderate interactions listed above.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with clinical evidence supporting its stated purpose. Major medication interactions have been identified, and safety information is well characterized.
This product combines traditional digestive bitter herbs with glycerin and potassium sorbate. If you take blood pressure medications, blood thinners, diabetes drugs, lithium, or MAOIs, or if you have kidney disease or high blood pressure, talk with your doctor or pharmacist before starting it — the interactions and cardiovascular effects are worth reviewing first.
Otherwise, it's generally well tolerated in the amounts used here, though the clinical evidence for its digestive effects is not established. Your doctor or pharmacist can help you decide whether it fits your individual situation.

Digestive Bitters Tonic by Nature's Sunshine Drug Interactions
HelloPharmacist Interaction Report
Digestive Bitters Tonic by Nature's Sunshine interacts with medications through its potassium sorbate, dandelion, stevia, gentian, and orange peel tincture content.
The most serious interaction is Major in severity: orange peel tincture with monoamine oxidase inhibitors (MAOIs) — a class of older antidepressants — can cause dangerously high blood pressure (hypertensive crisis) by increasing the effects of stimulant compounds in the orange peel.
Read the full breakdown — every affected drug type, severity by severity
Orange peel tincture also carries Major interactions with midazolam (Versed), a sedative medication, by increasing its blood levels and side effects. Multiple Moderate interactions affect several drug categories: potassium-sparing water pills and blood pressure medications (ACE inhibitors and ARBs) carry a risk of dangerously high potassium levels (hyperkalemia) from the potassium sorbate; dandelion interacts with blood thinners, blood sugar drugs, lithium, certain antibiotics (quinolones), and drugs processed by the liver through CYP1A2 and glucuronidation pathways; stevia theoretically increases lithium levels; gentian combined with blood pressure medications can lower blood pressure too much; and orange peel tincture interacts with QT-prolonging heart drugs, stimulant medications, caffeine, blood sugar drugs, cough suppressants (dextromethorphan), and several liver-metabolized drugs (CYP3A4 substrates).
Cardamom seed tincture has no known interactions documented in our data. We could not check phosphoric acid, water, or raspberry syrup — no interaction data is held for these.
Altogether, these interactions span 1,233 individual medications.

For each ingredient in Digestive Bitters Tonic 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.
Orange peel tincture
Midazolam (Versed)
Bitter orange might increase blood levels of midazolam.
One small clinical study shows that bitter orange juice can increase midazolam levels, likely through inhibition of cytochrome P450 3A4 (CYP3A4). Theoretically, bitter orange might increase the risk of midazolam-related adverse effects.
Monoamine Oxidase Inhibitors (Maois)
Theoretically, taking MAOIs with synephrine-containing bitter orange preparations might increase the hypertensive effects of synephrine, potentially leading to hypertensive crisis.
Bitter orange contains tyramine, octopamine, and synephrine, which are MAO substrates.
Antidiabetes Drugs
Theoretically, bitter orange might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Some clinical research shows that drinking a tea containing bitter orange and Indian snakeroot reduces fasting and postprandial glucose levels in patients with type 2 diabetes who are using antidiabetes drugs. However, it is unclear if these effects are due to bitter orange, Indian snakeroot, or the combination. An animal study also shows that p-synephrine in combination with gliclazide , a sulfonylurea, causes an additional 20% to 44% decrease in glucose levels when compared with gliclazide alone.
Caffeine
Bitter orange might increase blood pressure and heart rate when taken with caffeine.
Small clinical studies show that taking bitter orange in combination with caffeine can increase blood pressure and heart rate in otherwise healthy normotensive adults. Theoretically, this might increase the risk of serious cardiovascular adverse effects.
Colchicine
Bitter orange might affect colchicine levels.
Colchicine is a substrate of P-glycoprotein and cytochrome P450 3A4 (CYP3A4). Bitter orange has been reported to inhibit CYP3A4 and increase levels of CYP3A4 substrates. However, one small clinical study in healthy adults shows that drinking bitter orange juice 240 mL twice daily for 4 days and taking a single dose of colchicine 0.6 mg on the 4th day decreases colchicine peak serum levels by 24%, time to peak serum level by 1 hour, and overall exposure to colchicine by 20%. The clinical significance of this finding is unclear.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Bitter orange might increase levels of drugs metabolized by CYP3A4.
Small clinical studies suggest that single or multiple doses of freshly squeezed bitter orange juice 200-240 mL can inhibit CYP3A4 metabolism of drugs, causing increased drug levels and potentially increasing the risk of adverse effects. However, the extent of the effect of bitter orange on CYP3A4-mediated drug interactions is unknown. Some evidence suggests that bitter orange selectively inhibits intestinal CYP3A4, but not hepatic CYP3A4. Its effect on P-glycoprotein, which strongly overlaps with CYP3A4 interactions, is unclear. One small clinical study shows that drinking 8 ounces of freshly squeezed bitter orange juice has no effect on cyclosporine, which seems to be more dependent on hepatic CYP3A4 and P-glycoprotein than intestinal CYP3A4.
Dextromethorphan (Robitussin Dm, Others)
Bitter orange might increase blood levels of dextromethorphan.
One small clinical study shows that bitter orange juice increases dextromethorphan levels, likely through cytochrome P450 3A4 (CYP3A4) inhibition. Theoretically, bitter orange might increase the risk for dextromethorphan-related adverse effects.
Felodipine (Plendil)
Bitter orange might increase blood levels of felodipine.
One small clinical study shows that bitter orange juice increases felodipine levels, likely through cytochrome P450 3A4 (CYP3A4) inhibition. Theoretically, bitter orange might increase the risk for felodipine-related adverse effects.
Indinavir (Crixivan)
Bitter orange might increase blood levels of indinavir.
One small clinical study shows that bitter orange juice slightly increases indinavir levels, but this effect is likely to be clinically insignificant. Bitter orange selectively inhibits intestinal cytochrome P450 3A4 (CYP3A4); however, the metabolism of indinavir seems to be more dependent on hepatic CYP3A4. The effect of bitter orange on other protease inhibitors has not been studied.
Qt Interval-Prolonging Drugs
Theoretically, bitter orange might have an additive effect when combined with drugs that prolong the QT interval, potentially increasing the risk of ventricular arrhythmias.
One case report suggests that taking bitter orange in combination with other stimulants such as caffeine might prolong the QT interval in some patients.
Sildenafil (Viagra)
Bitter orange juice might increase blood levels of sildenafil.
A small clinical study in healthy adult males shows that drinking freshly squeezed bitter orange juice 250 mL daily for 3 days and taking a single dose of sildenafil 50 mg on the 3rd day increases the peak plasma concentration of sildenafil by 18% and the overall exposure to sildenafil by 44%. Theoretically, this may be due to inhibition of cytochrome P450 3A4 by bitter orange.
Stimulant Drugs
Theoretically, bitter orange might increase the risk of hypertension and adverse cardiovascular effects when taken with stimulant drugs.
Bitter orange appears to have stimulant effects.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, bitter orange might increase levels of drug metabolized by CYP2D6.
In vitro research shows that octopamine, a constituent of bitter orange, weakly inhibits CYP2D6 enzymes. This effect has not been reported in humans.
Dandelion
Anticoagulant/Antiplatelet Drugs
Theoretically, taking dandelion root along with anticoagulant or antiplatelet drugs might increase the risk of bruising and bleeding.
In vitro research suggests that dandelion root inhibits platelet aggregation.
Antidiabetes Drugs
Theoretically, dandelion might increase the risk for hypoglycemia when used with antidiabetes drugs.
Laboratory research suggests that dandelion extract may have moderate alpha-glucosidase inhibitor activity and might also increase insulin secretion. Also, in a case report, a 58-year-old woman with type 2 diabetes who was being treated with insulin developed hypoglycemia 2 weeks after beginning to eat salads containing dandelion.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, dandelion might increase levels of drugs metabolized by CYP1A2.
Laboratory research suggests that dandelion might inhibit CYP1A2. So far, this interaction has not been reported in humans. However, until more is known, watch for an increase in the levels of drugs metabolized by CYP1A2 in patients taking dandelion.
Glucuronidated Drugs
Theoretically, dandelion might increase the clearance of drugs that are UDP-glucuronosyltransferase substrates.
There is some preliminary evidence that dandelion might induce UDP-glucuronosyltransferase, a phase II enzyme.
Lithium
Theoretically, through diuretic effects, dandelion might reduce excretion and increase levels of lithium.
Animal research suggests that dandelion has diuretic properties. As diuretics can increase serum lithium levels, the dose of lithium might need to be decreased when taken with dandelion.
Potassium-Sparing Diuretics
Theoretically, dandelion might increase the risk of hyperkalemia when taken with potassium-sparing diuretics.
Dandelion contains significant amounts of potassium.
Quinolone Antibiotics
Theoretically, dandelion might lower fluoroquinolone levels.
Animal research shows that dandelion reduces absorption of ciprofloxacin and can lower levels by 73%. However, this effect has not been reported in humans.
Stevia
Lithium
Theoretically, stevia might decrease clearance and increase levels of lithium.
Animal research suggests that stevia extracts might have diuretic activity. Theoretically, increased reabsorption of lithium along with sodium might reduce excretion and increase levels of lithium.
Antidiabetes Drugs
Theoretically, stevia might increase the risk for hypoglycemia when combined with antidiabetes drugs.
Preliminary clinical research in patients with type 2 diabetes suggests that taking a single dose of stevia extract 1000 mg reduces postprandial blood glucose levels when taken with a meal. However, other clinical research in patients with type 1 or type 2 diabetes suggests that taking stevioside 250 mg three times daily does not significantly affect blood glucose levels or glycated hemoglobin (HbA1C) after three months of treatment.
Antihypertensive Drugs
Theoretically, combining stevia or stevia constituents with antihypertensive agents might increase the risk of hypotension.
Stevia extract and stevioside might lower blood pressure in patients with hypertension. However, other clinical research suggests that stevioside does not significantly lower blood pressure in patients with hypertension.
Gentian
Antihypertensive Drugs
Theoretically, taking gentian with antihypertensive drugs might increase the risk of hypotension.
In vitro research shows that gentian can cause vasodilation and lower blood pressure.
Potassium Sorbate
Ace Inhibitors (Aceis)
Using ACEIs with high doses of potassium increases the risk of hyperkalemia.
ACEIs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.
Angiotensin Receptor Blockers (Arbs)
Using ARBs with high doses of potassium increases the risk of hyperkalemia.
ARBs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.
Potassium-Sparing Diuretics
Concomitant use increases the risk of hyperkalemia.
Using potassium-sparing diuretics with potassium supplements increases the risk of hyperkalemia.
