HelloPharmacist Scorecard of Alpha-Lipoic Acid 100 mg by Natural Factors
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.
What’s inside
Full disclosure
This product contains one active ingredient: alpha-lipoic acid at 100 mg per capsule. It's a compound your body makes naturally and also gets from food, though only in small amounts.
The capsule itself is gelatin, and the other ingredients — microcrystalline cellulose, magnesium stearate, and silica — are inactive fillers and binders.
Does it work?
Moderate evidence
Alpha-lipoic acid is rated possibly effective for three uses in our data: diabetic nerve pain (neuropathy), high cholesterol, and weight management. That means there's some evidence it may help, but it's not definitive — more or better research is needed to be sure.
If you're considering it for one of these reasons, talk with your doctor or pharmacist about what the current evidence supports for your situation.
How safe is it?
Well-documented data
Alpha-lipoic acid is generally well tolerated. The most common side effects from the oral form are headache, heartburn, nausea, and vomiting — a small number of people report these.
Skin rash and itching have also been reported. Rare serious cases have raised concerns about an autoimmune insulin reaction, though this is uncommon.
The product can lower blood sugar, so it's best used under medical guidance if you have diabetes or take diabetes drugs. There isn't enough reliable safety data during pregnancy or breastfeeding, so the safety data advises against use in both.
If you're pregnant or nursing and interested in this supplement, talk with your obstetrician or pediatrician before starting.
Meds to double-check
Moderate interaction found
Check before taking this if you're on blood thinners or antiplatelet drugs (Moderate concern), chemotherapy agents like alkylating agents or antitumor antibiotics (Moderate concern), thyroid hormone replacement (Moderate concern), or diabetes medications (Minor concern). If you take any of these, run them through the checker on this page.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Alpha-lipoic acid may help with diabetic nerve pain, cholesterol, or weight — possibly, not certainly. If you take blood thinners, chemotherapy, thyroid hormone, or diabetes medication, check with your pharmacist first.
It's usually gentle on the stomach but can cause headache or nausea in some people. Avoid it during pregnancy or breastfeeding unless your doctor says otherwise.

Alpha-Lipoic Acid 100 mg by Natural Factors Drug Interactions
HelloPharmacist Interaction Report
Alpha-Lipoic Acid 100 mg by Natural Factors does interact with several medication types.
The most serious concern is with blood thinners and antiplatelet drugs (like warfarin, aspirin, or clopidogrel). Alpha-lipoic acid may increase bleeding risk because it can thin the blood slightly — in lab studies, it's shown to inhibit platelet clumping.
Read the full breakdown — every affected drug type, severity by severity
You'll also want to check if you're on chemotherapy drugs. Alpha-lipoic acid is an antioxidant, and there's theoretical concern it might interfere with alkylating agents and antitumor antibiotics, which work partly by generating cell-damaging free radicals.
If you take thyroid hormone (like levothyroxine), alpha-lipoic acid may reduce how well your body converts it to its active form, potentially weakening the drug's effect.
One more: if you're on diabetes medication, there's a Minor-level concern about low blood sugar, though larger studies haven't shown alpha-lipoic acid significantly lowers blood glucose on its own.
Altogether, these interactions span 262 individual medications. Run your exact prescriptions through the medication checker below before you start this supplement.

For each ingredient in Alpha-Lipoic Acid 100 mg with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Alpha-Lipoic Acid
Alkylating Agents
Theoretically, the antioxidant effects of alpha-lipoic acid might alter the effectiveness of alkylating agents.
The use of antioxidants like alpha-lipoic acid during chemotherapy is controversial. There are concerns that antioxidants could reduce the activity of chemotherapy drugs that generate free radicals. However, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that might interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as alpha-lipoic acid have on chemotherapy. Advise patients to consult their oncologist before using alpha-lipoic acid.
Anticoagulant/Antiplatelet Drugs
Theoretically, alpha-lipoic acid may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro, alpha-lipoic acid inhibits platelet aggregation.
Antitumor Antibiotics
Theoretically, the antioxidant effects of alpha-lipoic acid might alter the effectiveness of antitumor antibiotics.
The use of antioxidants like alpha-lipoic acid during chemotherapy is controversial. There are concerns that antioxidants could reduce the activity of antitumor antibiotic drugs, which work by generating free radicals. However, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that might interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as alpha-lipoic acid have on chemotherapy involving antitumor antibiotics. Advise patients to consult their oncologist before using alpha-lipoic acid.
Thyroid Hormone
Theoretically, alpha-lipoic acid might decrease the effects of thyroid hormone drugs.
Animal research suggests that co-administration of thyroxine with alpha-lipoic acid reduces conversion into the active T3 form.
Antidiabetes Drugs
Theoretically, taking alpha-lipoic acid with antidiabetes drugs might increase the risk of hypoglycemia.
Although some small clinical studies have suggested that alpha-lipoic acid can lower blood glucose levels, larger clinical studies in patients with diabetes have shown no clinically meaningful effect. Additionally, co-administration of single doses of alpha-lipoic acid and glyburide or acarbose did not cause detectable drug interactions in healthy volunteers.
