HelloPharmacist Scorecard of Astragalus 1000 mg by Double Wood Supplements

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

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: astragalus at 1,000 mg per capsule. Astragalus is a plant root used in traditional herbal practice, and it's delivered here in capsule form with gelatin, cellulose, and magnesium stearate as inactive ingredients.

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 Astragalus's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: supports immune system and cardiovascular health.
  • We looked for evidence on: Upper respiratory tract infection (URTI), Heart failure, Myocardial infarction (MI), Angina, Myocarditis, Adaptogenic stress support — and 1 related terms.
  • The closest evidence on file: Astragalus is rated "Insufficient Reliable Evidence To Rate" for Angina (Natural Medicines).
  • Also on file: Astragalus is rated "Insufficient Reliable Evidence To Rate" for Upper respiratory tract infection (URTI), Heart failure, Myocardial infarction (MI), Myocarditis.

The evidence we hold doesn't establish astragalus as effective for the conditions listed — allergic rhinitis (hay fever), amenorrhea, aplastic anemia, angina, asthma, and beta-thalassemia all carry a rating of insufficient reliable evidence. If you're thinking of using astragalus for one of these or another condition, it's worth discussing what the current research actually shows with your doctor or pharmacist.

The evidence, ingredient by ingredient Astragalus

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.

Astragalus is generally well tolerated in the short term in healthy adults, though quality human safety data is limited. Some trial participants have reported dizziness and other minor effects, though it's unclear whether astragalus caused them or something else did.

The safety data advises against astragalus during pregnancy and breastfeeding — there isn't enough reliable information to know it's safe in either situation, so talk with your doctor or pharmacist if you're pregnant, breastfeeding, or planning to become pregnant.

Side effects, ingredient by ingredient Astragalus

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 — Astragalus.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 208 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.

Before you start this product, double-check with your doctor or pharmacist if you take immunosuppressants, lithium, cyclophosphamide, or antidiabetes drugs — astragalus could theoretically affect how they work or their side-effect risk.

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.

Astragalus4 drug types · 208 drugs

Antidiabetes Drugs

Theoretically, taking astragalus with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research in humans shows that astragalus might have hypoglycemic effects. Theoretically, taking astragalus, especially in combination with other hypoglycemic agents, might increase the risk of hypoglycemia.

Likelihood Probable Evidence A
Cyclophosphamide

Theoretically, astragalus might interfere with cyclophosphamide therapy.
Evidence regarding the effect of astragalus on immunosuppression caused by cyclophosphamide is conflicting. Some animal research suggests that astragalus reverses cyclophosphamide-induced immunosuppression. However, other animal research shows no effect.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, astragalus might interfere with immunosuppressive therapy.
Astragalus seems to stimulate immune function. Theoretically, taking astragalus might decrease the effects of immunosuppressive therapy.

Likelihood Possible Evidence D
Lithium

Theoretically, astragalus might increase levels and adverse effects of lithium.
Animal research suggests that astragalus has diuretic properties. Theoretically, due to this diuretic effect, astragalus might reduce excretion and increase levels of lithium.

Astragalus 1000 mg by Double Wood Supplements: Common Questions

Does Astragalus 1000 mg by Double Wood Supplements interact with any medications?
Yes. Based on its ingredients, Astragalus 1000 mg has a known interaction with 208 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Astragalus 1000 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.
Is astragalus safe to take if I'm pregnant or breastfeeding?
Not enough reliable safety data exists to know either way. The safety data advises against it during pregnancy and breastfeeding. Talk with your doctor or pharmacist about your situation before taking it.
What side effects has astragalus caused in trials?
In clinical studies, a small number of participants reported dizziness and, rarely, symptoms like lacunar angina. However, we can't be sure astragalus actually caused these effects — they may have occurred for other reasons.
Does astragalus actually work for the conditions it claims to help?
The evidence we hold rates astragalus as having insufficient reliable evidence for allergic rhinitis, amenorrhea, aplastic anemia, angina, asthma, and beta-thalassemia. That means we don't have solid proof it works for these.
Can I take astragalus if I'm on blood sugar medication?
Astragalus might lower blood sugar on its own, so combining it with diabetes drugs could theoretically raise your risk of low blood sugar. Check with your doctor or pharmacist before taking it.
What's in the capsule besides astragalus?
The capsule itself is gelatin, and there's cellulose and magnesium stearate as binders and fillers — standard inactive ingredients to hold the capsule together.
