HelloPharmacist Scorecard of Avena Sativa 500 mg by BodSmith

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 16, 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.

Avena Sativa contains one active ingredient: oatstraw extract at 500 mg per capsule. Oatstraw is an extract from the oat plant and is used to support cholesterol and heart health.

The capsule also contains two inactive ingredients — gelatin and rice powder — which are binding and filler materials.

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 Oats's overall clinical evidence instead.

Strong

Strong clinical evidence supports Oats 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 ingredient's overall clinical evidence instead.
  • On file: Coronary heart disease (CHD) — rated "Likely Effective" (Natural Medicines).
  • On file: Dyslipidemia — rated "Likely Effective" (Natural Medicines).
  • On file: Diabetes — rated "Possibly Effective" (Natural Medicines).
  • On file: Gastric cancer — rated "Possibly Effective" (Natural Medicines).

Oatstraw extract is likely effective for lowering cholesterol (dyslipidemia) and supporting heart health in coronary heart disease. These ratings come from research on oats as a food and concentrated forms.

If you're taking this product for either of those purposes, the evidence backs its use.

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 are well tolerated when taken by mouth. The most common side effects are digestive: bloating, flatulence, abdominal distension, and an unpleasant taste.

These usually fade with continued use, and you can minimize them by starting with a lower dose and increasing gradually over time. Oats eaten as food are generally considered safe during pregnancy and while breastfeeding, though concentrated supplements like this one are less studied.

If you're pregnant or nursing, talk with your doctor or pharmacist about whether this product is right for you. People with difficulty chewing or conditions that slow small intestine movement should avoid it, as oats contain fiber that can rarely cause intestinal blockage.

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.

If you take insulin or antidiabetes drugs, you'll want to clear this product with your doctor or pharmacist first. Oats can add to their blood-sugar-lowering effect, which might require adjusting your dose.

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.

Avena Sativa may help with cholesterol and heart health, but the key caution is if you take insulin or diabetes medication — oats can lower blood sugar, and combined use raises hypoglycemia risk. Digestive side effects like bloating are common but usually settle down.

Check your medications with your doctor or pharmacist before you start, especially if you have diabetes.

Antidiabetes Drugs

Theoretically, oats may have additive effects with antidiabetic agents and might increase the risk of hypoglycemia.
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 500 mg by BodSmith: Common Questions

Does Avena Sativa 500 mg by BodSmith interact with any medications?
Yes. Based on its ingredients, Avena Sativa 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?
Avena Sativa 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.
Will this make my blood sugar too low?
Oats can lower blood glucose on their own. If you also take insulin or diabetes medications, the combined effect might increase the risk of low blood sugar (hypoglycemia). Talk with your doctor or pharmacist about monitoring and whether your medication dose may need adjusting.
What are the side effects?
The most common ones are digestive — bloating, gas, belly distension, and an odd taste. These usually go away as your body adjusts. Starting with a lower dose and building up slowly helps minimize them.
Is it safe to take while pregnant or breastfeeding?
Oats eaten as food are generally considered safe in pregnancy and while nursing. This is a concentrated supplement form, which is less studied, so it's worth discussing with your doctor or pharmacist to be sure it's right for you.
What does oatstraw extract actually do?
It's used to help lower cholesterol and support heart health. The evidence shows it's likely effective for both of those purposes.
Are there any fillers or other junk in here?
The capsule contains gelatin and rice powder as inactive ingredients — those are standard binders and fillers in supplements. The active ingredient is just the oatstraw extract.
