HelloPharmacist Scorecard of Kyolic Formula 104 by Kyolic
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
Kyolic Formula 104 has 2 active ingredients: lecithin and aged garlic extract powder. Lecithin is a fatty substance used in various health contexts, and aged garlic extract is a concentrated form of garlic that's been aged to reduce smell and alter its chemical profile.
The product also contains inactive ingredients — gelatin as the capsule material, silicon dioxide, and magnesium stearate.
Does it work?
Moderate evidence
The garlic in this formula is possibly effective for blood sugar control (diabetes), high blood pressure (hypertension), fatty liver disease, gum disease (periodontitis), and atherosclerosis — though the evidence isn't definitive. For lecithin, the data we hold shows it's likely ineffective for age-related mental decline (Alzheimer disease), and there isn't enough reliable evidence to rate it for other conditions like anxiety, bipolar disorder, or fatty liver disease linked to IV nutrition support.
How safe is it?
Well-documented data
Lecithin is likely safe during pregnancy and lactation. Garlic extract is generally well tolerated when taken by mouth, though common side effects include stomach upset, gas, bad breath, and body odor.
Rare serious concerns include increased bleeding risk. If you have an egg or soy allergy, lecithin may trigger an allergic skin reaction.
Garlic supplements can cause skin reactions, rashes, or flushing in some people, and there's a case report of mouth ulcers. The product's aged garlic extract should be less likely to cause stomach upset than raw garlic, but talk with your doctor before using it if you're pregnant, nursing, or have a bleeding disorder.
Meds to double-check
Moderate interaction found
Before taking Kyolic Formula 104, check with your pharmacist if you're on blood thinners or antiplatelet drugs (including warfarin), blood pressure medications, diabetes drugs, HIV protease inhibitors, or tacrolimus (Prograf). The aged garlic extract can change how these work or increase bleeding risk.
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.
This product may help with blood sugar and blood pressure, but it's not a strong fit if you take blood thinners, diabetes medications, or blood pressure drugs without checking first. The garlic-related interactions span hundreds of medications, so run your prescriptions through our tool before you start.
If you tolerate garlic well and your doctor clears it, the side effects are usually mild.

Kyolic Formula 104 by Kyolic Drug Interactions
HelloPharmacist Interaction Report
Kyolic Formula 104 contains aged garlic extract, which interacts with a number of medications.
The most serious concern is with blood thinners (anticoagulants) and antiplatelet drugs like warfarin — garlic can increase bleeding risk by boosting antiplatelet activity and increasing prothrombin time, which measures how long blood takes to clot. This is a Moderate severity interaction.
Read the full breakdown — every affected drug type, severity by severity
Garlic in this product may also lower blood pressure and blood sugar, so if you're on blood pressure medications (antihypertensives) or diabetes drugs, there's a risk of low blood pressure (hypotension) or low blood sugar (hypoglycemia). Additionally, garlic can affect how your liver and intestines metabolize certain drugs, including HIV protease inhibitors and the immunosuppressant tacrolimus — it may reduce some drug levels or increase others.
Lecithin, the product's other active ingredient, has no interactions documented in our data.
Altogether, these interactions span 977 individual medications. Use the checker below to look up your exact prescriptions before starting this product.

For each ingredient in Kyolic Formula 104 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.
Aged Garlic extract powder
Anticoagulant/Antiplatelet Drugs
Garlic may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Raw garlic and a variety of garlic extracts have antiplatelet activity and can increase prothrombin time.
Antidiabetes Drugs
Theoretically, taking garlic with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research suggests that garlic and garlic extract lower blood glucose levels in healthy and diabetic individuals.
Antihypertensive Drugs
Theoretically, taking garlic with antihypertensive drugs might increase the risk of hypotension.
In human research, both garlic and garlic extracts have blood pressure-lowering effects.
Atazanavir (Reyataz)
Theoretically, garlic might decrease levels and effects of atazanavir.
In a case report, a patient consuming six stir-fried garlic cloves three times weekly developed suboptimal atazanavir levels and increases in HIV viral load. While the exact cause of this interaction is unclear, there is speculation that garlic might decrease the intestinal absorption of atazanavir or increase its metabolism by inducing cytochrome P450 3A4 (CYP3A4). Until more is known, advise patients not to consume large amounts of garlic while taking atazanavir.
Cytochrome P450 2E1 (Cyp2E1) Substrates
Garlic might increase levels of drugs metabolized by CYP2E1.
Clinical research suggests garlic oil can inhibit the activity of CYP2E1 by 39%. Use garlic oil cautiously in patients taking drugs metabolized by these enzymes.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, garlic products containing allicin might induce intestinal CYP3A4 and inhibit hepatic CYP3A4. This may increase or decrease levels of drugs metabolized by CYP3A4.
Some human research suggests that garlic may induce INTESTINAL CYP3A4, reducing levels of drugs metabolized by this enzyme. This is primarily based on a study showing that taking a specific allicin-containing garlic product (GarliPure Maximum Allicin Formula, Natrol Inc.) twice daily for 3 days reduces saquinavir levels by approximately 50%. It is speculated that the allicin constituent induced CYP3A4 in the gut mucosa. Another study shows that giving docetaxel intravenously, bypassing the CYP3A4 enzymes in the gut mucosa, along with the same specific garlic product for 12 consecutive days, does not affect docetaxel levels. Conversely, there is concern that garlic may inhibit HEPATIC CYP3A4. In a single case report, increased tacrolimus levels and liver injury occurred in a liver transplant patient after taking a specific garlic supplement (Garlicin Cardio, Nature's Way) at up to three times the manufacturer recommended dose for 7 days. Several other studies have evaluated the impact of other garlic formulations on CYP3A4 substrates and have found no effect. Most of the products in these studies provided little or no allicin.
Isoniazid
Theoretically, garlic might decrease levels of isoniazid.
Animal research suggests that an aqueous extract of garlic reduces isoniazid levels by about 65%. Garlic reduced the maximum concentration (Cmax) and area under the curve (AUC), but not the half-life, of isoniazid. This suggests that garlic extract might inhibit isoniazid absorption across the intestinal mucosa; however, the exact mechanism of this potential interaction is not known.
Protease Inhibitors (Pis)
Theoretically, garlic products containing allicin might decrease levels of PIs.
Protease inhibitors are metabolized by cytochrome P450 3A4 (CYP3A4) isoenzymes. There is concern that garlic products containing allicin might induce intestinal CYP3A4, reducing plasma levels of protease inhibitors. This is primarily based on a study showing that taking a specific garlic product (GarliPure Maximum Allicin Formula, Natrol Inc.) twice daily for 3 days reduces levels of saquinavir, a PI, by approximately 50%. It is speculated that the allicin constituent induce CYP3A4 in the gut mucosa. Several studies have evaluated the impact of other garlic formulations on CYP3A4 substrates and have found no effect. Most of the products in these studies provided little or no allicin.
Saquinavir (Fortovase, Invirase)
Theoretically, garlic containing allicin might decrease levels of saquinavir.
Saquinavir is a substrate of cytochrome P450 3A4 (CYP3A4) isoenzymes. There is concern that garlic products containing allicin might induce intestinal CYP3A4 and cause subtherapeutic levels of saquinavir. This is primarily based on a pharmacokinetic study showing that taking a specific garlic product (GarliPure Maximum Allicin Formula, Natrol Inc.) twice daily for 3 days reduces saquinavir levels by approximately 50%. It is speculated that the allicin constituent induces CYP3A4 in the gut mucosa. Several pharmacokinetic studies have evaluated the impact of other garlic formulations on CYP3A4 substrates and have found no effect. Most of the products in these studies provided little or no allicin. Until more is known about this potential interaction, use garlic containing allicin cautiously in patients taking saquinavir.
Sofosbuvir (Sovaldi)
Theoretically, taking garlic with sofosbuvir might decrease its effectiveness.
Animal research in rats shows that giving aged garlic extract 120 mg/kg orally daily for 14 days decreases the area under the concentration time curve (AUC) after a single sofosbuvir dose of 40 mg/kg by 36%, increases the clearance by 63%, and decreases the plasma concentrations at 1 and 8 hours by 35% and 58%, respectively. This interaction is hypothesized to be due to induction of intestinal P-glycoprotein expression by garlic.
Tacrolimus (Prograf)
Theoretically, garlic might increase levels of tacrolimus.
In one case report, a liver transplant patient taking tacrolimus experienced increased tacrolimus levels and liver injury after taking a specific garlic supplement (Garlicin Cardio, Nature's Way) at up to three times the manufacturer recommended dose for 7 days. It is speculated that garlic inhibited hepatic cytochrome P450 3A4 (CYP3A4), which increased plasma levels of tacrolimus.
Warfarin (Coumadin)
Theoretically, garlic might increase the risk of bleeding with warfarin.
Raw garlic and a variety of garlic extracts have antiplatelet activity and can increase prothrombin time. In addition, there is a report of two patients who experienced an increase in a previously stabilized international normalized ratio (INR) with concomitant garlic and warfarin use. However, this report has been subsequently debated due to limited clinical information. Other clinical studies have not identified an effect of garlic on INR, warfarin pharmacokinetics, or bleeding risk. More evidence is needed to determine the safety of using garlic with warfarin.
