What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This juice contains two active ingredients: sodium and maqui berry. The product also includes a number of inactive ingredients — fruit juices and powders (acai, blueberry, raspberry, pomegranate), citrus pectin, grape seed extract, ascorbic acid, citric acid, natural flavor, and potassium sorbate as a preservative.

Does it work?

Strong 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.

Strong

Strong 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: Constipation — rated "Effective" (Black Psyllium) (Natural Medicines).
  • On file: Coronary heart disease (CHD) — rated "Likely Effective" (Black Psyllium) (Natural Medicines).
  • On file: Cystic fibrosis — rated "Likely Effective" (Sodium) (Natural Medicines).
  • On file: Amphotericin B nephrotoxicity — rated "Possibly Effective" (Sodium) (Natural Medicines).

The evidence we hold does not establish that maqui berry is effective for dry eye, prediabetes, or psychological well-being — the data rates these as insufficient. Sodium's effectiveness data in our files relates to cystic fibrosis (rated likely effective) and amphotericin B nephrotoxicity (possibly effective), which aren't relevant to what this juice is marketed for.

Overall, we don't have established evidence for the product's main claims.

The evidence, ingredient by ingredient Black Psyllium Sodium Maqui

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 2 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Sodium is well tolerated at normal dietary amounts up to the recommended daily intake level, but high intake is linked to high blood pressure and heart strain. The safety notes advise against sodium supplements or very high intake without medical guidance.

Maqui berry in food amounts is likely safe, but supplement safety hasn't been well studied — the safety data we hold recommends avoiding supplement amounts of maqui berry because there isn't enough information. High sodium intake is associated with rare but serious risks including worsened heart disease, high blood pressure, and kidney disease.

Regarding pregnancy and breastfeeding, sodium is rated likely safe, but maqui berry carries insufficient data — there's no established safety profile for either ingredient in pregnancy or lactation, so you'd want to discuss this with your doctor or pharmacist before use.

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 3 of the 3 matched ingredients can interact with medications — Black Psyllium, Maqui, Sodium.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications; heart-rhythm medications; lithium.
  • For scale: 2,064 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.

If you take blood pressure medications (antihypertensives), lithium, corticosteroids, diabetes medications, didanosine, sodium phosphates, or tolvaptan, check with your doctor or pharmacist before starting this juice. The sodium content and potential low-blood-sugar effect of maqui berry are the main concerns.

The bottom line

Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

This juice combines sodium with maqui berry, and while neither is dangerous in food amounts, the sodium content and maqui berry's limited safety data mean you should talk it over with your doctor or pharmacist first — especially if you take blood pressure medications, lithium, or diabetes drugs. Your own healthcare provider can tell you whether the sodium level is appropriate for your health situation.

General Statements

Maqui berries (Aristotelia chilensis) are native to the Patagonia region of South America, growing wild in what many regard as one of the most pristine places on the planet. The unique climate and diverse soil content inherent to this vast, mountainous region of Chile is believed to play a central role in Maqui's extraordinary antioxidant content. For centuries, indigenous cultures have relied on this remarkable fruit as a source of both nourishment and natural wellness. Today, scientific research has taught us that Maqui berries possess among the highest known ORAC value (Oxygen Radical Absorption Capacity) of any superfruit on the planet.

The exceptional free radical fighting properties associated with Maqui can be attributed to it's naturally-occurring anthocyanins - a powerful class of antioxidants that have shown highly effective in quenching free radicals.

Each ingredient & the kinds of drugs it affects

For each ingredient in Maqui SuperFruit Antioxidant Juice 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.

Dietary Fiber7 drug types · 2,025 drugs

Carbamazepine (Tegretol)

Theoretically, black psyllium might reduce the effects of carbamazepine and increase the risk for convulsions.
Theoretically, black psyllium might reduce carbamazepine absorption. A preliminary study using blond psyllium reported decreased carbamazepine bioavailability due to binding of the drug to psyllium, as well as reduction of available fluid in the gut for dissolution of the drug. This interaction may also occur with black psyllium.

Likelihood Probable Evidence D
Lithium

Theoretically, taking black psyllium at the same time as lithium might reduce lithium absorption.
The fiber in black psyllium might reduce lithium absorption and plasma levels. Some case reports describe a reduction in plasma lithium levels with concomitant administration of blond psyllium. This was reversed when psyllium was stopped. This interaction may also occur with black psyllium.

Likelihood Probable Evidence D
Metformin (Glucophage)

Theoretically, black psyllium might increase the therapeutic and adverse effects of metformin.
Animal research shows that concurrent consumption of blond psyllium with metformin slows and increases the absorption of metformin. This interaction may also occur with black psyllium. To avoid changes in absorption, take psyllium 30-60 minutes after metformin.

Likelihood Possible Evidence D
Olanzapine (Zyprexa)

Theoretically, taking black psyllium at the same time as olanzapine might reduce olanzapine absorption.
The fiber in black psyllium might decrease the absorption of olanzapine. A single case report describes a reduction in the effectiveness of olanzapine when it was concomitantly administered with an unspecified type of psyllium 3 grams orally twice daily. This effect was reversed when psyllium was stopped.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, taking black psyllium at the same time as digoxin might reduce digoxin absorption and decrease digoxin levels.
Psyllium might bind digoxin in the gut. However, some clinical evidence suggests that psyllium does not impact digoxin absorption.

Likelihood Unlikely Evidence B
Ethinyl Estradiol

Theoretically, taking black psyllium at the same time as ethinyl estradiol might alter levels of estradiol.
Concurrent use of blond psyllium with ethinyl estradiol results in a slight increase in the extent of ethinyl estradiol absorption and a slower rate of absorption. This is unlikely to be clinically significant.

Likelihood Unlikely Evidence D
Oral Drugs

Theoretically, psyllium might increase, decrease, or have no effect on the absorption of oral drugs.
Psyllium seems to have variable effects on drug absorption. To avoid changes in absorption, take psyllium 30-60 minutes after oral medications. Animal research shows that blond psyllium delays and increases the absorption of metformin and ethinyl estradiol. Case reports and animal research suggest that blond psyllium might reduce absorption of lithium, digoxin, olanzapine, and carbamazepine. Finally, some pharmacokinetic studies show that psyllium does not affect the absorption of levothyroxine or warfarin. Although many of these studies evaluated blond psyllium, the fiber content in black psyllium may have similar effects.

Likelihood Possible Evidence B
Dietary Fiber full monograph & interactions

Sodium7 drug types · 205 drugs

Antihypertensive Drugs

Theoretically, a high intake of dietary sodium might reduce the effectiveness of antihypertensive drugs.
High intake of dietary sodium can increase systolic and diastolic blood pressure. Also, high intake of sodium may necessitate increased use of antihypertensive medications to achieve blood pressure control in some patients, such as those with chronic kidney disease.

Likelihood Probable Evidence A
Corticosteroids

Concomitant use of mineralocorticoids and some glucocorticoids with sodium supplements might increase the risk of hypernatremia.
Mineralocorticoids and some glucocorticoids (corticosteroids) cause sodium retention. This effect is dose-related and depends on mineralocorticoid potency. It is most common with hydrocortisone, cortisone, and fludrocortisone, followed by prednisone and prednisolone.

Likelihood Possible Evidence D
Didanosine (Videx)

Concomitant use of didanosine with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia.
Didanosine formulations contain a significant amount of sodium.

Likelihood Probable Evidence C
Lithium

Altering dietary intake of sodium might alter the levels and clinical effects of lithium.
High sodium intake can reduce plasma concentrations of lithium by increasing lithium excretion. Reducing sodium intake can significantly increase plasma concentrations of lithium and cause lithium toxicity in patients being treated with lithium carbonate. Stabilizing sodium intake is shown to reduce the percentage of patients with lithium level fluctuations above 0.8 mEq/L. Patients taking lithium should avoid significant alterations in their dietary intake of sodium.

Likelihood Probable Evidence B
Sodium Phosphates

Theoretically, concomitant use of sodium phosphate with sodium supplements might increase the risk of hypernatremia.
Use of high doses (> 45 mL in 24 hours) of sodium phosphate, such as those used for bowel cleansing before surgery, can lead to serious electrolyte disturbances, including hypernatremia. The risk of hypernatremia is highest in the elderly and people with other risk factors for electrolyte disturbances.

Likelihood Possible Evidence D
Sodium-Containing Drugs

Concomitant use of sodium-containing drugs with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia and long-term sodium-related complications.
The Chronic Disease Risk Reduction (CDRR) intake level of 2.3 grams of sodium daily indicates the intake at which it is believed that chronic disease risk increases for the apparently healthy population. Some medications contain high quantities of sodium. When used in conjunction with sodium supplements or high-sodium diets, the CDRR may be exceeded. Additionally, concomitant use may increase the risk for hypernatremia; this risk is highest in the elderly and people with other risk factors for electrolyte disturbances.

Likelihood Possible Evidence D
Tolvaptan (Samsca)

Theoretically, concomitant use of tolvaptan with sodium might increase the risk of hypernatremia.
Tolvaptan is a vasopressin receptor 2 antagonist that is used to increase sodium levels in patients with hyponatremia. Patients taking tolvaptan should use caution with the use of sodium salts such as sodium chloride.

Likelihood Probable Evidence C
Sodium full monograph & interactions

Maqui Berry1 drug type · 86 drugs

Antidiabetes Drugs

Theoretically, maqui fruit extract may increase the risk of hypoglycemia when used with antidiabetes drugs.
Animal research shows that maqui berry reduces fasting blood glucose. However, maqui berry extract taken orally, either as a single dose or daily for 3 months, does not decrease fasting blood glucose in prediabetic patients. It is unknown whether it might reduce blood glucose levels in patients with diabetes.

Maqui SuperFruit Antioxidant Juice by NOW: Common Questions

Does Maqui SuperFruit Antioxidant Juice by NOW interact with any medications?
Yes. Based on its ingredients, Maqui SuperFruit Antioxidant Juice has a known interaction with 2,063 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Maqui SuperFruit Antioxidant Juice contains 5 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.
Is maqui berry proven to work for anything?
In the data we hold, there's insufficient evidence to say maqui berry is effective for dry eye, prediabetes, or psychological well-being. The research isn't established enough to make that claim.
Can I take this if I'm on blood pressure medication?
You'll need to check with your doctor or pharmacist first. This juice contains sodium, and high sodium intake can reduce how well blood pressure medications work, so your provider needs to know about it.
Is the sodium in this juice a concern?
Normal dietary sodium is fine, but this product is a supplement, not just food. The safety notes advise against sodium supplements or very high intake without medical guidance — talk it over with your doctor or pharmacist to know if this amount is right for you.
Is maqui berry safe if I'm pregnant or breastfeeding?
We don't have enough safety data on maqui berry in pregnancy or breastfeeding. Sodium is rated likely safe, but you'll want to discuss this juice with your doctor or pharmacist before using it during pregnancy or while nursing.
What are the inactive ingredients?
The juice contains acai berry, blueberry, raspberry, and pomegranate juices, maqui berry powder, citrus pectin, grape seed extract, ascorbic acid, citric acid, natural flavor, and potassium sorbate as a preservative.
