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.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients: iron and American ginseng extract. Iron is a mineral your body needs to make healthy red blood cells and carry oxygen; it's used when you don't have enough of it in your system.

American ginseng is a plant extract traditionally used to support immune function and possibly help with cold and flu symptoms. The capsule itself is made from vegetable cellulose, with vegetable magnesium stearate as a flow agent.

Does it work?

Moderate 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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Stress, energy, immune support and wellness.
  • We looked for evidence on: Athletic performance, Cognitive function, Fatigue, Upper respiratory tract infection (URTI), Adaptogenic support, Mental clarity — and 1 related terms.
  • The strongest evidence on file: Iron is rated "Possibly Effective" for Cognitive function (Natural Medicines).
  • Also on file: American Ginseng is rated "Possibly Effective" for Upper respiratory tract infection (URTI).
  • Also on file: Iron is rated "Possibly Ineffective" for Athletic performance.

Iron is effective for treating iron deficiency anemia and anemia of chronic disease, and is also effective for pregnancy-related iron deficiency. It may be helpful for heart failure, though the evidence is less strong.

American ginseng has possibly effective evidence for upper respiratory tract infections (common colds and similar illnesses). For other uses listed on the label—like American ginseng for anemia of chronic disease or breast cancer—the evidence isn't established in our data.

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Iron is generally well tolerated at recommended doses, but excess iron can be toxic, so it should only be used when there's a real need. The most common side effects from oral iron are stomach upset: abdominal pain, constipation, diarrhea, nausea, and vomiting.

Rare serious concerns include stomach ulcers and, with long-term overuse without monitoring, acquired hemochromatosis (iron overload). American ginseng is generally well tolerated in the short term in healthy adults, but long-term safety hasn't been well studied and quality varies between products.

For pregnancy, iron is often recommended but your prenatal care provider should guide the dose; American ginseng safety data is insufficient in pregnancy, so it's best avoided. During breastfeeding, iron at appropriate doses is generally considered acceptable, but American ginseng has too little safety data, so avoidance is the safer choice.

Talk with your doctor or pharmacist about what's right for you.

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 2 of the 2 matched ingredients can interact with medications — Iron, American Ginseng.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; Parkinson's medications.
  • For scale: 295 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 take this product, double-check if you're on warfarin (a blood thinner)—American ginseng can reduce its effectiveness. Also check for iron-sensitive medications: levodopa, quinolone or tetracycline antibiotics, bisphosphonates, methyldopa, levothyroxine, mycophenolate mofetil, and penicillamine.

If you take diabetes drugs, antidepressants called MAOIs, or immunosuppressants, run those by your pharmacist too. Separating doses by a few hours can help with many of these.

American Ginseng extract4 drug types · 217 drugs

Warfarin (Coumadin)

American ginseng seems to decrease the effectiveness of warfarin therapy.
Healthy patients receiving warfarin 5 mg daily, who also take American ginseng 1 gram twice daily, seem to have a significantly reduced international normalized ratio (INR).

Likelihood Likely Evidence B
Antidiabetes Drugs

Theoretically, taking American ginseng with antidiabetes drugs might increase the risk of hypoglycemia.
American ginseng seems to lower postprandial blood glucose. Theoretically, concomitant use with antidiabetes drugs might enhance blood glucose lowering effects and possibly cause hypoglycemia.

Likelihood Probable Evidence B
Immunosuppressants

Theoretically, American ginseng use might interfere with immunosuppressive therapy.
American ginseng seems to stimulate immune function. Theoretically, American ginseng might decrease the effectiveness of immunosuppressant drugs.

Likelihood Possible Evidence D
Monoamine Oxidase Inhibitors (Maois)

Theoretically, American ginseng can interfere with MAOI therapy.
There is one case report of insomnia, headache, and tremors when an unspecified ginseng product was used with phenelzine (Nardil), an MAOI. There is also one case report of hypomania when an unspecified ginseng product was used with phenelzine. Theoretically, American ginseng may interfere with MAOI therapy.

Likelihood Possible Evidence D
American Ginseng extract full monograph & interactions

Iron13 drug types · 80 drugs

Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)

Iron might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption when taken in a fasting state.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide and iron can be taken together if taken with food. However, if taken on an empty stomach, bictegravir/emtricitabine/tenofovir alafenamide should not be taken with, or 2 hours after, iron containing products.

Likelihood Probable Evidence D
Bisphosphonates

Iron reduces the absorption of bisphosphonates.
Advise patients that doses of bisphosphonates should be separated by at least two hours from doses of all other medications, including supplements such as iron. Divalent cations, including iron, can decrease absorption of bisphosphonates by forming insoluble complexes in the gastrointestinal tract.

Likelihood Probable Evidence D
Denosumab (Prolia, Others)

Administration of intravenous iron within one month of denosumab administration might increase the risk of severe hypophosphatemia and hypocalcemia.
A case of severe hypocalcemia (albumin corrected calcium 6.88 mg/dL, ionized calcium 3.68 mg/dL) and hypophosphatemia (<0.5 mg/dL) with respiratory acidosis, QT interval prolongation, and nonsustained ventricular tachycardia was reported in a 76-year-old male who had received an iron polymaltose infusion within 2 weeks of a subcutaneous injection of denosumab. Serum parathyroid hormone was also elevated (348 pg/mL). Subsequent iron infusions with iron polymaltose and ferric carboxymaltose were followed by transient hypophosphatemia, but without hypocalcemia. Additionally, a literature review describes 6 additional cases of hypophosphatemia and hypocalcemia in patients 52-92 years of age who had been administered intravenous iron as either ferric carboxymaltose or iron polymaltose and subcutaneous denosumab within 1-4 weeks of each other.

Likelihood Possible Evidence D
Dolutegravir (Tivicay)

Iron might decrease dolutegravir levels by reducing its absorption.
Advise patients to take dolutegravir at least 2 hours before or 6 hours after taking iron. Pharmacokinetic research shows that iron can decrease the absorption of dolutegravir from the gastrointestinal tract through chelation. When taken under fasting conditions, a single dose of ferrous fumarate 324 mg orally along with dolutegravir 50 mg reduces overall exposure to dolutegravir by 54%.

Likelihood Probable Evidence B
Integrase Inhibitors

Theoretically, taking iron along with integrase inhibitors might decrease the levels and clinical effects of these drugs.
Iron is a divalent cation. There is concern that iron may decrease the absorption of integrase inhibitors from the gastrointestinal tract through chelation. One pharmacokinetic study shows that iron can decrease blood levels of the specific integrase inhibitor dolutegravir through chelation. Also, other pharmacokinetic research shows that other divalent cations such as calcium can decrease the absorption and levels of some integrase inhibitors through chelation.

Likelihood Possible Evidence D
Levodopa

Iron might decrease levodopa levels by reducing its absorption.
Advise patients to separate doses of levodopa and iron as much as possible. There is some evidence in healthy people that iron forms chelates with levodopa, reducing the amount of levodopa absorbed by around 50%. The clinical significance of this hasn't been determined.

Likelihood Probable Evidence B
Levothyroxine (Synthroid, Others)

Iron might decrease levothyroxine levels by reducing its absorption.
Advise patients to separate levothyroxine and iron doses by at least 2 hours. Iron can decrease the absorption and efficacy of levothyroxine by forming insoluble complexes in the gastrointestinal tract.

Likelihood Probable Evidence B
Methyldopa (Aldomet)

Iron might decrease methyldopa levels by reducing its absorption.
Advise patients to separate methyldopa and iron doses by at least 2 hours. Iron can decrease the absorption of methyldopa from the gastrointestinal tract through chelation, resulting in increases in blood pressure.

Likelihood Probable Evidence B
Mycophenolate Mofetil (Cellcept)

Theoretically, iron might decrease mycophenolate mofetil levels by reducing its absorption.
Advise patients to take iron 4-6 hours before, or 2 hours after, mycophenolate mofetil. It has been suggested that a decrease of absorption is possible, probably by forming nonabsorbable chelates. However, mycophenolate pharmacokinetics are not affected by iron supplementation in available clinical research.

Likelihood Unlikely Evidence D
Penicillamine (Cuprimine, Depen)

Iron might decrease penicillamine levels by reducing its absorption.
Advise patients to separate penicillamine and iron doses by at least 2 hours. Oral iron supplements can reduce absorption of penicillamine by 30% to 70%, probably due to chelate formation. In people with Wilson's disease, this interaction has led to reduced efficacy of penicillamine.

Likelihood Probable Evidence D
Quinolone Antibiotics

Iron might decrease levels of quinolone antibiotics by reducing their absorption.
Advise patients to separate quinolone antibiotics and iron doses by at least 2 hours. Iron decreases the absorption of quinolones due to formation of insoluble complexes in the gastrointestinal tract.

Likelihood Probable Evidence D
Tetracycline Antibiotics

Iron might decrease levels of tetracycline antibiotics by reducing their absorption.
Advise patients to take iron at least 2 hours before or 4 hours after tetracycline antibiotics. Concomitant use can decrease absorption of tetracycline antibiotics from the gastrointestinal tract by 50% to 90%.

Likelihood Probable Evidence D
Chloramphenicol

Theoretically, taking chloramphenicol with iron might reduce the response to iron therapy in iron deficiency anemia.
Chloramphenicol interferes with erythrocyte maturation. However, since chloramphenicol isn't usually taken for prolonged periods, this isn't likely to be clinically significant.

American Ginseng Root by Solgar: Common Questions

Does American Ginseng Root by Solgar interact with any medications?
Yes. Based on its ingredients, American Ginseng Root has a known interaction with 295 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
American Ginseng Root 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.
Does this product have any fillers?
No. This product contains only the two active ingredients—iron and American ginseng extract—plus vegetable cellulose and vegetable magnesium stearate, which are inactive ingredients used to form and fill the capsule.
Can I take this while pregnant?
Iron is often recommended in pregnancy, but your prenatal care provider needs to guide your dose. American ginseng, though, doesn't have enough safety data in pregnancy, so it's best avoided during pregnancy. Talk with your doctor about whether this product is right for you.
Can I take this while breastfeeding?
Iron at appropriate doses is generally considered acceptable while breastfeeding, but check with your provider on the dose. American ginseng has too little safety data while breastfeeding, so avoidance is the safer choice. Your pharmacist or doctor can help you weigh your options.
What does the American ginseng in this product actually do?
American ginseng is possibly effective for upper respiratory tract infections—that's colds and similar illnesses. It may also stimulate your immune system. The evidence for other uses isn't established in our data.
Are there side effects from the iron?
Yes. Common side effects include stomach pain, constipation, diarrhea, nausea, and vomiting. These usually happen when iron is taken on an empty stomach; taking it with food can help. Serious side effects are rare but can include stomach ulcers with long-term use.
Is this safe if I don't actually have an iron deficiency?
No. The safety notes say excess iron can be toxic and supplements should only be used when there's a real need. If you're not sure whether you're low on iron, ask your doctor or pharmacist before starting.
