HelloPharmacist Scorecard of Dark Chocolate Stevia Extract by NOW
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
Full disclosure
This liquid contains one active ingredient: stevia extract, a zero-calorie sweetener derived from the stevia plant. It's used as a sugar substitute.
The product also contains vegetable glycerin, natural dark chocolate flavor, and grain alcohol as inactive ingredients that carry the extract and add flavor.
Does it work?
Couldn't assess
We don't have reliable evidence yet to rate stevia extract for diabetes control, high blood pressure, or weight management. While some research hints that stevia might lower blood glucose or blood pressure, other studies don't show a clear effect — the data aren't firm enough to say whether it works for these purposes.
How safe is it?
Well-documented data
Purified stevia at food-sweetener doses is generally recognized as safe by food regulators. High-dose supplements like this one, however, lack extensive safety data, so caution is warranted.
The most common side effects — bloating, dizziness, headache, muscle aches, nausea, and numbness — tend to be mild and often fade after the first week. Allergic reactions are rare but possible.
Meds to double-check
Moderate interaction found
Lithium (a mood stabilizer) is the top concern — stevia might raise its level in your blood. Also check before starting if you take blood pressure medications or diabetes drugs, where stevia could theoretically strengthen their effects.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This stevia extract works as a sugar-free sweetener, but we don't have strong evidence it treats diabetes, high blood pressure, or weight gain. If you take lithium, blood pressure medications, or diabetes drugs, talk with your doctor or pharmacist before starting — stevia could affect how these work.
Even if you're not on those medications, check your full list with the tool on this page first.

Dark Chocolate Stevia Extract by NOW Drug Interactions
HelloPharmacist Interaction Report
NOW Dark Chocolate Stevia Extract, a liquid stevia extract, has documented interactions across its single active ingredient.
The most serious concern is with lithium (a mood stabilizer), where stevia might theoretically increase lithium levels to potentially unsafe ranges — stevia appears to reduce how your body clears the drug, and its possible diuretic effect might change how lithium is reabsorbed in your kidneys.
Read the full breakdown — every affected drug type, severity by severity
Stevia also interacts with two other drug types at minor severity. Blood pressure medications (antihypertensives) could theoretically have their blood-pressure-lowering effect amplified if combined with stevia, raising the risk of excessively low blood pressure.
Similarly, diabetes medications might theoretically work too well with stevia, raising the risk of low blood sugar (hypoglycemia) — though clinical evidence is mixed on whether stevia actually lowers blood glucose meaningfully in people with diabetes.
Altogether, these interactions span 259 individual medications. Before starting this product, run your exact prescriptions through the medication checker on this page, and talk with your doctor or pharmacist if you take lithium, blood pressure drugs, or diabetes medications.

Stevia extract
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.
