HelloPharmacist Scorecard of R-Alpha Lipoic Acid 200 mg by KRK Supplements
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: R-alpha-lipoic acid, 200 mg per capsule. It's the R-form specifically, which is the naturally occurring version your body recognizes.
The capsule also contains inactive ingredients — gelatin (the capsule shell), calcium carbonate, magnesium stearate, and silica — which are standard excipients that help form and stabilize the supplement.
Does it work?
Moderate evidence
The evidence for alpha-lipoic acid shows it may help with a few conditions. For diabetic neuropathy — nerve damage from diabetes — and for high cholesterol and obesity, the research rates it as possibly effective.
That means there's some clinical support, but it's not airtight; talk with your doctor about whether it fits your situation.
How safe is it?
Well-documented data
Alpha-lipoic acid is generally well tolerated in most adults. The most common side effects from oral use are headache, heartburn, nausea, and vomiting.
Some people report dizziness or skin rash and itching. Serious side effects are rare, though a few case reports have raised questions about insulin autoimmune syndrome (a condition where your immune system attacks cells that make insulin).
Because it can lower blood sugar, use it under medical guidance if you're at risk. There isn't enough safety data to recommend it during pregnancy or while breastfeeding, so you'll want to avoid it during those times and talk to your doctor or pharmacist.
Meds to double-check
Moderate interaction found
Before you start this supplement, double-check with us if you take blood thinners or antiplatelet drugs (Moderate interaction risk), any chemotherapy medications including alkylating agents or antitumor antibiotics (Moderate), thyroid hormone replacement (Moderate), or diabetes medications (Minor). No interactions are documented for the ingredient we could check beyond these categories.
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.
R-Alpha Lipoic Acid may be worth considering if you have diabetic nerve pain, high cholesterol, or obesity and your doctor thinks it could help. If you take blood thinners, chemotherapy drugs, thyroid medication, or diabetes drugs, you should absolutely check with your pharmacist first — there are documented theoretical interactions.
It's generally well tolerated, but because it can lower blood sugar, medical guidance is a good idea.

R-Alpha Lipoic Acid 200 mg by KRK Supplements Drug Interactions
HelloPharmacist Interaction Report
R-Alpha Lipoic Acid 200 mg by KRK Supplements does interact with several medication types.
The most serious concern is with blood thinners and antiplatelet drugs (like warfarin, aspirin, clopidogrel). Alpha-lipoic acid can theoretically thin your blood further and increase bleeding risk.
If you take any of these, you'll want to check with us before starting.
Read the full breakdown — every affected drug type, severity by severity
Alpha-lipoic acid may also affect how chemotherapy drugs work — both alkylating agents and antitumor antibiotics — because of its antioxidant activity. There's theoretical concern it could reduce their effectiveness, which is why oncology patients should talk to their cancer team before adding this supplement.
Thyroid hormone replacement drugs are another consideration. Animal research suggests alpha-lipoic acid might reduce how well your body converts thyroid medication into its active form, potentially lowering its effect.
Finally, if you take diabetes medications, there's a minor theoretical risk of low blood sugar (hypoglycemia), though larger studies haven't shown alpha-lipoic acid causes meaningful blood sugar drops on its own. Altogether, these interactions span 262 individual medications.

For each ingredient in R-Alpha Lipoic Acid 200 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.
R-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.
