HelloPharmacist Scorecard of MaquiBerry 1,000 mg by Natrol

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
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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Natrol MaquiBerry 1,000 mg contains one active ingredient: maqui berry extract at 1,000 mg per capsule. Maqui is a South American berry that proponents use to support eye health and metabolic function.

The capsule also contains inactive ingredients—hypromellose, cellulose, silica, magnesium stearate, and water—which help form and stabilize the product.

Does it work?

Couldn't assess
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
Not assessable

This is a single-ingredient Maqui product and its label doesn't state a use — see Maqui's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for maqui berry is not yet established in our data. We rate its use for dry eye, prediabetes, and psychological well-being as having insufficient reliable evidence to rate.

In other words, there isn't enough solid research right now to say whether it works for these purposes. If you're considering it for a specific health goal, your doctor or pharmacist can help you weigh what's known so far.

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Maqui berry is likely safe in food amounts, but supplement safety hasn't been studied well. The safety data we hold advises against supplement amounts due to not enough information.

No adverse effects are documented in our data. We don't hold safety information for maqui berry in pregnancy or lactation.

Talk with your doctor or pharmacist before taking this product if you're pregnant, nursing, or planning to become pregnant.

Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Maqui.
  • The most serious interaction on file is rated Minor.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 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 antidiabetes drugs or any medication for blood sugar, check your specific medications with the tool on this page before adding maqui berry—there is a minor theoretical risk of low blood sugar. No other medication interactions are documented for this ingredient.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Only minor medication interactions are documented, and some safety-information gaps remain.

Natrol MaquiBerry may interest someone looking to support eye health or metabolic function, but the evidence for its effectiveness isn't established yet. The main caution is for anyone on diabetes or blood-sugar medication—you'll want to check that combination with your own doctor or pharmacist first.

Since supplement safety hasn't been well studied, discuss this product with your healthcare provider before starting.

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.
