HelloPharmacist Scorecard of Alpha Lipoic Acid 100 mg by Vitabase
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. Alpha-lipoic acid is a compound your body produces naturally; it acts as an antioxidant and plays a role in energy metabolism.
The capsule also contains inactive ingredients—rice powder, silica, magnesium stearate, and gelatin—that help form and preserve the supplement.
Does it work?
Moderate evidence
According to the clinical evidence we hold, alpha-lipoic acid is rated possibly effective for diabetic neuropathy (nerve pain related to diabetes), high cholesterol (hyperlipidemia), and weight management (obesity). This means there is some promising research, but the evidence isn't yet conclusive.
If you're considering it for one of these uses, talk with your doctor about whether it makes sense alongside your current treatment plan.
How safe is it?
Well-documented data
Alpha-lipoic acid is generally well tolerated by most adults. The most common side effects when taken by mouth are headache, heartburn, nausea, and vomiting.
Some people report dizziness, skin rash, or itching. Because the supplement can lower blood sugar, it should be used under medical guidance—especially if you take diabetes medications.
There is not enough reliable safety information available, so the safety data advises against use during pregnancy and while breastfeeding. Rare serious effects like insulin autoimmune syndrome have been reported, though these are uncommon.
Meds to double-check
Moderate interaction found
Before starting this product, have your pharmacist check if you take blood thinners or antiplatelet drugs (Moderate risk of increased bleeding), chemotherapy medications (Moderate risk of reduced effectiveness), thyroid hormone replacement (Moderate risk of reduced thyroid drug effectiveness), or diabetes medications (Minor risk of low blood sugar). If you're unsure whether your drugs are affected, use the checker on this page.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
Alpha-lipoic acid may be worth considering if you have diabetic nerve pain, high cholesterol, or are managing weight—and your doctor agrees it fits your plan. Be cautious if you take blood thinners, chemotherapy, thyroid medication, or diabetes drugs; check with your pharmacist first.
Avoid it during pregnancy and breastfeeding. It's generally well tolerated, but mild side effects like nausea and headache do occur in some people.

Alpha Lipoic Acid 100 mg by Vitabase Drug Interactions
HelloPharmacist Interaction Report
Vitabase Alpha Lipoic Acid has several documented interactions with medications.
The most serious concern is with blood thinners and antiplatelet drugs (such as warfarin, aspirin, and clopidogrel): alpha-lipoic acid may thin the blood further and increase bleeding risk. This is rated Moderate severity.
Read the full breakdown — every affected drug type, severity by severity
Additionally, alpha-lipoic acid may interfere with chemotherapy drugs. It can theoretically reduce how well alkylating agents and antitumor antibiotics work, since these drugs rely on generating free radicals to kill cancer cells and alpha-lipoic acid's antioxidant action may counteract that.
Both are Moderate severity concerns. If you're undergoing cancer treatment, talk to your oncologist before starting this supplement.
Thyroid hormone medications (levothyroxine and others) may also be affected—alpha-lipoic acid might lower their effectiveness. This is also Moderate severity.
Finally, there's a Minor-severity concern with diabetes medications: while alpha-lipoic acid is unlikely to significantly lower blood sugar on its own, combining it with antidiabetes drugs theoretically raises the risk of low blood sugar. Altogether, these interactions span 262 individual medications.

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.
