HelloPharmacist Scorecard of Astragalus by Nature's Way

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 2 of its 2 active ingredients.
  • “Astragalus Root Extract” is listed as a grouped ingredient — the label gives one combined amount (250 mg) without saying how much of each component you get.

Astragalus by Nature's Way contains two active ingredients: astragalus root extract and astragaloside, a compound believed to be one of astragalus's key active constituents. The capsules also hold hypromellose and magnesium stearate as inactive ingredients to hold the formula together.

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 health.
  • We looked for evidence on: Upper respiratory tract infection (URTI), Allergic rhinitis (hay fever), Asthma, Chronic obstructive pulmonary disease (COPD), HIV/AIDS, Hepatitis B — and 4 related terms.
  • The closest evidence on file: Astragalus is rated "Insufficient Reliable Evidence To Rate" for Allergic rhinitis (hay fever) (Natural Medicines).
  • Also on file: Astragalus is rated "Insufficient Reliable Evidence To Rate" for Asthma, Chronic obstructive pulmonary disease (COPD), Upper respiratory tract infection (URTI), Hepatitis B, and more.

The evidence for astragalus isn't established in the data we hold. Studies have looked at it for allergic rhinitis (hay fever), loss of menstruation (amenorrhea), aplastic anemia, angina, asthma, and beta-thalassemia, but the research is too limited or conflicting to make a solid claim about how well it works for any of these conditions.

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 when taken orally short-term by healthy adults, though quality human safety data is limited. Some people in clinical trials reported dizziness or palpitations, though these effects may not have been caused by astragalus itself.

The safety data advises against taking it during pregnancy or while breastfeeding because there isn't enough reliable information to know whether it's safe.

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.

Check with your pharmacist if you take immunosuppressants, antidiabetes drugs, lithium, or cyclophosphamide. These are Moderate-severity interactions, meaning astragalus could meaningfully affect how these medications work.

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.

Astragalus is worth a closer look if you're dealing with a condition you hope it might help and you don't take any of the medication types listed below. If you're on an immunosuppressant, lithium, an antidiabetes drug, or cyclophosphamide, talk with your pharmacist before starting — the interactions are real possibilities, not just theoretical.

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.

Likelihood Probable Evidence D

Astragalus by Nature's Way: Common Questions

Does Astragalus by Nature's Way interact with any medications?
Yes. Based on its ingredients, Astragalus 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 contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 pregnant or breastfeeding?
No — there isn't enough reliable safety data, so the data advises against it in both pregnancy and while breastfeeding. Talk with your doctor or pharmacist about whether it's right for your situation.
What side effects should I watch for?
Dizziness and palpitations (heart racing or fluttering) have been reported in some people, though they may not have been caused by astragalus. Rash and itching are possible too. Stop and check with your pharmacist if anything feels off.
How long can I safely take this?
It's generally well tolerated short-term in healthy people, but quality human safety data for long-term use is limited. Your pharmacist can give you personalized guidance based on how long you're considering.
Does astragalus actually work for hay fever or other conditions?
The evidence isn't clear enough to say for sure. Studies have looked at it for hay fever, loss of menstruation, anemia, angina, asthma, and other conditions, but the research is too limited or mixed to make a solid recommendation.
