HelloPharmacist Scorecard of Avena sativa 575 mg by Swanson

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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: Avena sativa Whole Plant Extract, a concentrated form of oats, supplied at 575 mg per capsule. The capsules also contain three inactive ingredients — gelatin, magnesium stearate, and silica — which serve as the capsule shell and binding agents.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Oats's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: sexual sensation and sensitivity enhancement.
  • We looked for evidence on: Anxiety, sexual dysfunction, erectile dysfunction, libido.
  • The closest evidence on file: Oats is rated "Insufficient Reliable Evidence To Rate" for Anxiety (Natural Medicines).

Avena sativa is rated as Likely Effective for two cardiovascular conditions: high cholesterol (dyslipidemia) and coronary heart disease. The evidence supports its use for these lipid-related conditions.

We don't hold effectiveness data in our records for other uses.

The evidence, ingredient by ingredient Oats

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 1 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.

Oats as a supplement are generally well tolerated. The most common side effects are digestive — bloating, flatulence, abdominal distension, and an unpleasant taste — especially when you first start taking them.

These usually fade as your body adjusts, and you can minimize them by starting low and increasing your dose gradually. Oats eaten as food are considered safe in pregnancy and while breastfeeding, though concentrated supplement forms like this one are less studied.

If you're pregnant or nursing and considering this product, talk with your pharmacist for personalized guidance.

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 — Oats.
  • 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.

Check with your pharmacist before taking this if you're on insulin or any antidiabetes drug (medications that help manage blood sugar). Both carry a Moderate risk of low blood sugar when combined with oats.

Your dose may need adjusting.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This supplement makes sense if you're looking to support cholesterol and heart health and you don't take insulin or blood sugar medication. If you do manage diabetes with medication, check with your pharmacist or doctor first — oats can lower blood glucose and may require a dose adjustment.

Everyone should start with a low dose to avoid digestive bloating.

Consuming oats can decrease blood glucose in patients with diabetes. In those who require insulin, taking oats 100 grams daily for 2 days reduces the insulin dose required to achieve metabolic control.

Likelihood Possible Evidence D
Insulin

Concomitant use of oats and insulin might increase the risk of hypoglycemia.
In patients with insulin-dependent type 2 diabetes, taking oats 100 grams daily for 2 days reduces the insulin dose required to achieve metabolic control.

Avena sativa 575 mg by Swanson: Common Questions

Does Avena sativa 575 mg by Swanson interact with any medications?
Yes. Based on its ingredients, Avena sativa 575 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?
Avena sativa 575 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'm diabetic and on medication?
Not without checking first. Oats lower blood glucose, and if you're already on insulin or diabetes pills, that effect adds up — you could end up with blood sugar that's too low. Your pharmacist or doctor may want to adjust your medication dose or monitor you more closely.
What side effects should I expect?
Most people experience mild digestive effects when starting oats — bloating, gas, abdominal distension, and sometimes an unpleasant taste. These usually settle down as your body adapts. Start with a lower dose and work up slowly to minimize them.
Is this safe to take during pregnancy or while breastfeeding?
Oats eaten as food are safe in pregnancy and while nursing, but concentrated supplements like this one haven't been studied as thoroughly. There isn't enough data to know for certain either way, so talk with your pharmacist or doctor before you start it.
Does this actually help with cholesterol?
Yes — oats are rated as Likely Effective for high cholesterol and heart disease. The evidence supports using them for lipid-related conditions.
What's in the capsule besides the active ingredient?
The capsule itself is gelatin, and there's magnesium stearate and silica to help bind and flow the powder. Those are standard inactive ingredients — no fillers in the sense of useless bulk.
