HelloPharmacist Scorecard of Freeze-Dried Acai 500 mg 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
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.

This product contains one active ingredient: organic freeze-dried acai, the pulp of a South American berry supplied at 500 mg per capsule. The capsule itself is made from cellulose; the inactive ingredients also include cellulose powder, magnesium stearate, and stearic acid as binders and anti-caking agents.

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 Acai product and its label doesn't state a use — see Acai'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 acai in treating aging skin, athletic performance, erectile dysfunction, or high cholesterol is insufficient to rate. We don't have reliable data showing it works for any of these uses.

The evidence, ingredient by ingredient Acai

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.

Acai as a food is generally well tolerated, but concentrated supplements haven't been studied as thoroughly — high doses and long-term use aren't well characterized. For pregnancy and breastfeeding, there isn't enough safety information on acai supplements; the data we hold advises caution.

Talk with your doctor or pharmacist about whether this product is right for you if you're pregnant or nursing.

Side effects, ingredient by ingredient Acai

Meds to double-check

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?
  • 1 of the 1 matched ingredient can interact with medications — Acai.
  • The most serious interaction on file is rated Moderate.
  • 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 (including insulin, metformin, sulfonylureas, or others), you should double-check with your doctor or pharmacist before starting acai. Blood sugar control could shift, and your diabetes medication dose might need adjustment.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

Acai is familiar as a food, but as a concentrated supplement there's limited evidence it works for the claims you might hear. If you take diabetes medication, you'll want to check with your doctor or pharmacist before adding this — acai may affect your blood sugar control.

For most other people, there are no documented interactions, but the safety data in supplements remains thin.

Freeze-Dried Acai 500 mg by NOW: Common Questions

Does Freeze-Dried Acai 500 mg by NOW interact with any medications?
Yes. Based on its ingredients, Freeze-Dried Acai 500 mg has a known interaction with 86 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Freeze-Dried Acai 500 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
Can I take this if I have diabetes?
Acai may theoretically interfere with how well your diabetes medication works or how stable your blood sugar stays — it can raise or lower fasting glucose unpredictably. Check with your doctor or pharmacist before starting, because your medication might need adjustment.
Is acai safe during pregnancy or while breastfeeding?
The safety data on acai supplements during pregnancy and breastfeeding is not established. Talk with your doctor or pharmacist for personalized advice.
Does this actually help with high cholesterol or weight loss?
The evidence isn't there yet. We don't have reliable data showing acai works for cholesterol or obesity.
What exactly is freeze-dried acai?
It's the pulp of an acai berry that's had its water removed and then dried. That makes it concentrated and shelf-stable — one 500 mg capsule here replaces a much larger amount of fresh or liquid acai.
Are there any fillers in this capsule?
The capsule contains cellulose (the capsule material itself), cellulose powder, magnesium stearate, and stearic acid — all standard binders and anti-caking agents to keep the powder from clumping.
