HelloPharmacist Scorecard of Liver Chol by Sunshine Naturals
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
Liver Chol contains 11 ingredients, most of them B vitamins and amino acids that support liver health. The active ingredients include vitamin B12, pantothenic acid, choline bitartrate, methionine, niacinamide, vitamin B2, vitamin B1, liver concentrate, inositol complex, vitamin B6, and desiccated liver.
There are no other inactive ingredients listed.
Does it work?
Strong evidence
The evidence for this product varies by ingredient. Vitamin B12 is effective for B12 deficiency and likely effective for cyanide poisoning; it's possibly effective for canker sores and a nerve-pain condition called postherpetic neuralgia.
Niacinamide is likely effective for pellagra and possibly effective for acne, high phosphate in blood, osteoarthritis, and diabetes. Vitamin B6 is effective for a type of anemia and B6 deficiency, likely effective for high homocysteine, and possibly effective for pregnancy-related nausea.
Inositol is possibly effective for polycystic ovary syndrome and metabolic syndrome. For most other uses listed in the research, the evidence is either insufficient to rate or shows the ingredient is possibly ineffective—we don't have effectiveness data established for vitamin B2, choline, methionine, liver extract, or pantothenic acid for the conditions listed.
How safe is it?
Well-documented data
Most of these ingredients are generally well tolerated at normal doses. Vitamin B12, pantothenic acid, niacinamide, and vitamin B2 are considered likely safe in pregnancy and lactation at recommended amounts.
Choline and inositol are likely safe in pregnancy but should be used only under a doctor's guidance at supplement doses. Methionine and liver extract carry more caution in pregnancy — methionine supplement doses haven't been proven safe during pregnancy, and liver extract can carry very high vitamin A, which may harm a developing baby.
Vitamin B6 is usually safe in pregnancy at recommended amounts but is listed as possibly unsafe at high doses. The most common side effects are mild: nausea, diarrhea, and stomach upset with several ingredients; vitamin B2 can turn urine bright yellow.
Rare serious effects include nerve damage (sensory neuropathy) from very high doses of vitamin B6 over time, and a very rare severe low potassium (hypokalemia) with B12 when it corrects certain types of anemia. Liver extract carries theoretical concern about contamination from animal sources, though no cases have been reported in humans.
Meds to double-check
Moderate interaction found
Before taking Liver Chol, check with your doctor or pharmacist if you take blood thinners like warfarin (niacinamide and liver extract may affect them — Moderate and Minor severity), antihypertensive drugs (vitamin B6 — Moderate), seizure medications like phenytoin, phenobarbital, or carbamazepine (vitamin B6 and niacinamide — Moderate), antidiabetes drugs (inositol may lower blood sugar — Moderate), metformin (vitamin B12 can be depleted by it — Minor), amiodarone for heart rhythm (vitamin B6 — Moderate), atropine (choline — Minor), iron supplements or medications (liver extract — Minor), or levodopa for Parkinson's disease (vitamin B6, though not if you also take carbidopa — Minor). No interactions are documented for the vitamin B1 in this product.
The bottom line
Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
Liver Chol is a B-vitamin and amino-acid supplement aimed at supporting liver function, with some ingredients backed by decent evidence for specific uses like B12 deficiency or B6 for pregnancy nausea. It's generally well tolerated, but it does interact with blood thinners, some blood-pressure and seizure medications, and can add to your iron intake if you're already supplementing.
If you take warfarin, any seizure medication, blood-pressure drugs, metformin, or iron supplements, talk with your own doctor or pharmacist before starting this product to make sure it's safe for your situation.

HelloPharmacist Interaction Report
Liver Chol by Sunshine Naturals does interact with medications, mainly through its vitamin B12, niacinamide, vitamin B6, and liver extract content.
The most serious interaction is niacinamide with blood thinners (anticoagulants) like warfarin — niacinamide can increase warfarin's effect and raise your bleeding risk, a Moderate-severity concern.
Read the full breakdown — every affected drug type, severity by severity
Vitamin B6 at high doses may lower blood pressure further if you're already on blood-pressure medications (Moderate), and can increase the side effects of certain seizure drugs like phenytoin and phenobarbital (Moderate). Niacinamide also interacts with some seizure and heart medications.
Liver extract may contain vitamin K, which theoretically could reduce warfarin's effect, and also contains iron that can add to your total iron intake if you're taking iron supplements or medications (both Minor). Vitamin B12 has a Minor interaction with metformin, a diabetes medication, since metformin can lower B12 levels over time.
Choline has a Minor interaction with atropine.
We could not check vitamin B1 — we hold no data for it. Altogether, these interactions span 445 individual medications.

For each ingredient in Liver Chol 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.
Vit. B6
Amiodarone (Cordarone)
Theoretically, vitamin B6 might increase the photosensitivity caused by amiodarone.
Despite initial case reports suggesting that pyridoxine may have a protective effect against amiodarone-induced photosensitivity, preliminary clinical research suggests that pyridoxine may actually exacerbate this adverse effect.
Antihypertensive Drugs
Theoretically, vitamin B6 may have additive effects when used with antihypertensive drugs.
Research in hypertensive rats shows that vitamin B6 can decrease systolic blood pressure. Similarly, clinical research in patients with hypertension shows that taking high doses of vitamin B6 may reduce systolic and diastolic blood pressure, possibly by reducing plasma levels of epinephrine and norepinephrine.
Phenobarbital (Luminal)
High doses of vitamin B6 may reduce the levels and clinical effects of phenobarbital.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenobarbital, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenobarbital to avoid high doses of vitamin B6.
Phenytoin (Dilantin)
High doses of vitamin B6 may reduce the levels and clinical effects of phenytoin.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenytoin, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenytoin to avoid high doses of vitamin B6.
Levodopa
Vitamin B6 may increase the metabolism of levodopa when taken alone, but not when taken in conjunction with carbidopa.
Vitamin B6 (pyridoxine) enhances the metabolism of levodopa, reducing its clinical effects. However, this interaction does not occur when carbidopa is used concurrently with levodopa (Sinemet). Therefore, it is not likely to be a problem in most people.
Niacinamide
Anticoagulant/Antiplatelet Drugs
Theoretically, niacinamide may have additive effects when used with anticoagulant or antiplatelet drugs, especially in patients on hemodialysis.
Several cases of thrombocytopenia have been reported for hemodialysis patients treated with niacinamide 1 gram daily. Hemodialysis patients receiving niacinamide had almost a three-fold higher risk of developing thrombocytopenia when compared with those receiving placebo.
Carbamazepine (Tegretol)
Niacinamide might increase the levels and adverse effects of carbamazepine.
Plasma levels of carbamazepine were increased in two children given high-dose niacinamide, 60-80 mg/kg/day. This might be due to inhibition of the cytochrome P450 enzymes involved in carbamazepine metabolism. There is not enough data to determine the clinical significance of this interaction.
Primidone (Mysoline)
Niacinamide might increase the levels and adverse effects of primidone.
Case reports in children suggest niacinamide 60-100 mg/kg/day reduces hepatic metabolism of primidone to phenobarbital, and reduces the overall clearance rate of primidone; however, there is not enough data to determine the clinical significance of this potential interaction.
Warfarin (Coumadin)
There is limited evidence that niacinamide may increase the anticoagulant effects of warfarin.
In a case report, a patient on warfarin developed an elevated international normalized ratio (INR) of 8.4 after taking niacinamide 500 mg twice daily for 10 days. The patient's INR was previously stable, ranging between 2 and 3, with no other changes to current medications or diet reported. The elevated INR returned to the therapeutic range after receiving vitamin K and discontinuing niacinamide.
Inositol Complex
Antidiabetes Drugs
Theoretically, taking inositol with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research shows that inositol lowers blood glucose levels and glycated hemoglobin (HbA1c) levels in patients with diabetes.
Vitamin B12
Metformin (Glucophage)
Metformin, a common medication used to manage type 2 diabetes, has been associated with lower vitamin B12 levels in some individuals. Prolonged use of metformin can interfere with the absorption of B12 in the digestive system, potentially leading to a deficiency in this essential vitamin.
Vitamin B2
Tetracycline Antibiotics
Theoretically, taking riboflavin with tetracycline antibiotics may decrease the potency of these antibiotics.
In vitro research suggests that riboflavin may inhibit the potency of tetracycline antibiotics. It is not clear if this effect is clinically significant, as this interaction has not been reported in humans.
Choline Bitartrate
Atropine
Theoretically, choline might decrease the effects of atropine in the brain.
Animal research shows that administering choline one hour before administering atropine can attenuate atropine-induced decreases in brain levels of acetylcholine. Theoretically, concomitant use of choline and atropine may decrease the effects of atropine.
Liver concentrate
Iron
Liver extract can contain heme iron. Taking liver extract with iron-containing medications or supplements may increase total iron intake and could increase the risk of gastrointestinal adverse effects or excessive iron accumulation. The risk is greater with high doses, prolonged use, or in individuals with hemochromatosis or another iron-overload disorder. Review the iron content of the liver extract and the total elemental iron dose. Avoid unnecessary duplicate iron supplementation and consider monitoring ferritin and transferrin saturation when clinically appropriate.
Warfarin (Coumadin)
Liver extract products may contain small and variable amounts of vitamin K. Theoretically, starting, stopping, or substantially changing the amount of liver extract used could reduce the anticoagulant effect of warfarin and lower the INR. However, this interaction has not been directly studied or reported in humans, and the vitamin K content of liver extract products is generally not standardized. Consider monitoring the INR after a meaningful change in liver extract use.
