HelloPharmacist Scorecard of ALA by NutraBio
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, a compound your body naturally produces and also finds in foods like spinach and broccoli. Alpha-lipoic acid works as an antioxidant—it helps neutralize harmful molecules in your cells.
There are no inactive ingredients in this powder; it's just alpha-lipoic acid.
Does it work?
Moderate evidence
Alpha-lipoic acid is rated possibly effective for diabetic neuropathy (nerve damage from diabetes) and for lowering cholesterol and triglycerides (hyperlipidemia). It's also possibly effective for weight management (obesity).
These ratings mean the evidence is promising but not yet conclusive—more research would strengthen the case.
How safe is it?
Well-documented data
Alpha-lipoic acid is generally well tolerated in most adults. The most common side effects from the powder form are headache, heartburn, nausea, and vomiting.
Some people report dizziness, skin rash, or itching. Serious side effects are rare, though a few case reports have raised questions about a rare immune condition affecting insulin.
Because alpha-lipoic acid can lower blood sugar, it's best used under medical guidance if you're taking it regularly. There isn't enough reliable safety information to recommend it during pregnancy or while breastfeeding—talk with your doctor or pharmacist about what makes sense for your situation.
Meds to double-check
Moderate interaction found
Before taking this product, double-check with your pharmacist if you take blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel)—alpha-lipoic acid may increase bleeding risk. Also flag any chemotherapy drugs (Moderate risk), thyroid medication like levothyroxine (Moderate risk), or antidiabetes drugs (Minor risk).
These interactions are all documented, and your exact medications matter.
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 help with diabetic nerve pain and cholesterol, but it's not a first-line treatment. If you take blood thinners, thyroid medication, diabetes drugs, or chemotherapy, you need to check with your pharmacist or doctor before starting this product.
It's safe for most people when used as directed, but it does lower blood sugar and shouldn't be started without medical input if you have diabetes.

ALA by NutraBio Drug Interactions
HelloPharmacist Interaction Report
NutraBio's ALA is a single-ingredient product containing alpha-lipoic acid, and it does interact with several medication types.
The most serious concern is with blood thinners and antiplatelet drugs (like warfarin or aspirin): alpha-lipoic acid may increase bleeding risk because it can thin the blood itself, and this interaction is rated Moderate.
Read the full breakdown — every affected drug type, severity by severity
Alpha-lipoic acid may also interfere with chemotherapy drugs—both alkylating agents and antitumor antibiotics—because its antioxidant properties could theoretically reduce how well these cancer drugs work. These are also Moderate-severity interactions.
If you're on cancer treatment, this is worth a detailed conversation with your oncologist before adding ALA.
Thyroid hormone medications (like levothyroxine) may also be affected; animal research suggests alpha-lipoic acid might lower how much active thyroid hormone your body produces, a Moderate-severity interaction. Antidiabetes drugs carry a Minor interaction risk—theoretically, taking ALA with them could lower blood sugar further—though large studies show ALA itself hasn't had a strong blood-sugar-lowering effect.
Altogether, these interactions span 262 individual medications. Check your exact prescriptions with the search tool on this page before starting.

For each ingredient in ALA 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.
