HelloPharmacist Scorecard of K4 by TriPharm
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
K4 contains 4 active ingredients. Vanadyl sulfate is a form of vanadium, a mineral that may help with blood sugar control and has a possible role in bone health.
Alpha-lipoic acid is an antioxidant compound your body makes naturally and which may support nerve health and weight management. Kre-Alkalyn is a buffered form of creatine, an amino acid that fuels muscle energy during exertion.
Di-arginine malate is an amino acid compound meant to support muscle function and endurance. The product has no inactive fillers or binders listed.
Does it work?
Moderate evidence
The evidence for K4's ingredients is mixed. Vanadium is likely effective for vanadium deficiency but has insufficient evidence for athletic performance, cancer, diabetes, or cholesterol support.
Alpha-lipoic acid is possibly effective for nerve damage (diabetic neuropathy), cholesterol, and weight management. Creatine is possibly effective for muscle strength, athletic performance, and sarcopenia (age-related muscle loss), but possibly ineffective for Huntington disease and bone density.
Di-arginine malate's effectiveness is not established in our data.
How safe is it?
Well-documented data
Vanadyl sulfate is generally well tolerated at low doses but can cause stomach upset, diarrhea, and nausea above safe limits, and long-term high doses may harm the kidneys. Allergic reactions (rash, itching) are rare but have been reported.
Alpha-lipoic acid is generally well tolerated orally but commonly causes headache, heartburn, nausea, and skin rash; in rare cases, it has raised concerns about an autoimmune insulin reaction. Creatine is generally well tolerated in healthy adults but may cause water retention, muscle cramps, diarrhea, and dehydration; rare case reports mention kidney injury and muscle breakdown.
Those with kidney problems should be cautious with this product.
Meds to double-check
Moderate interaction found
Check your medications before taking K4, especially: blood thinners (anticoagulants/antiplatelets)—vanadyl sulfate and alpha-lipoic acid may increase bleeding risk; diabetes drugs—both vanadyl sulfate and alpha-lipoic acid may lower blood sugar too much; thyroid hormones—alpha-lipoic acid may reduce their effect; and chemotherapy drugs (alkylating agents and antitumor antibiotics)—alpha-lipoic acid's antioxidant effects may interfere with how they work. Run your exact medications 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.
K4 may be worth considering if you're looking for support with muscle strength, athletic performance, or blood sugar management—but it's not right for everyone. If you take blood thinners, diabetes medications, thyroid hormones, or chemotherapy, talk with your doctor or pharmacist before starting this product, since the ingredients may interact.
Those with kidney problems should check with their healthcare provider first. Your doctor or pharmacist can help you weigh whether K4 fits your needs.

HelloPharmacist Interaction Report
TriPharm K4 interacts with medications through its vanadyl sulfate and alpha-lipoic acid content.
The most serious documented interactions are Moderate in severity: vanadyl sulfate may increase bleeding risk with blood thinners (anticoagulants/antiplatelets), and alpha-lipoic acid may reduce how well thyroid hormone drugs work or interfere with certain chemotherapy agents.
Read the full breakdown — every affected drug type, severity by severity
Vanadyl sulfate carries a Moderate interaction with antidiabetes drugs—it may lower blood sugar levels too much. Alpha-lipoic acid also interacts with antidiabetes medications at Minor severity, with a theoretical risk of low blood sugar (hypoglycemia).
Additionally, alpha-lipoic acid may theoretically interfere with alkylating agents and antitumor antibiotics (chemotherapy drugs that work by creating free radicals), though the clinical significance remains uncertain.
We could not check di-arginine malate—we hold no interaction data for it. Kre-Alkalyn (creatine) shows no interactions documented in our data.
Altogether, these interactions span 263 individual medications.

For each ingredient in K4 with known interactions, here are the types of medications they 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.
Vanadyl Sulfate
Anticoagulant/Antiplatelet Drugs
Theoretically, vanadium might increase the risk of bleeding when taken with anticoagulant/antiplatelet drugs.
In vitro research shows that the sodium orthovanadate form of vanadium prolongs clotting time, likely through inhibition of thrombin and factor Xa.
Antidiabetes Drugs
Theoretically, vanadium might increase the risk of hypoglycemia when taken with antidiabetes drugs.
A few very small clinical studies in patients with type 2 diabetes show that the vanadyl sulfate form of vanadium increases insulin sensitivity and might lower blood glucose levels.
