What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 8 of its 8 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Isochrome contains eight active ingredients: vitamin B6, lipase (a digestive enzyme), coenzyme Q10, riboflavin, boron, potassium, L-carnitine, and chromium. Each plays a different role—B vitamins and coenzyme Q10 support energy and cellular function, lipase aids digestion, potassium and chromium support heart and blood sugar regulation, boron supports bone health, and L-carnitine supports energy production and heart function.

The product also contains inactive ingredients including fructose, citric acid, apple fiber, and flavorings.

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Blood sugar support and cardiovascular health.
  • We looked for evidence on: Cardiovascular disease (CVD), Coronary heart disease (CHD), Congestive heart failure (CHF), Diabetes, Chromium deficiency, Coenzyme Q10 deficiency — and 4 related terms.
  • The strongest evidence on file: Chromium is rated "Likely Effective" for Chromium deficiency (Natural Medicines).
  • Also on file: Coenzyme Q10 is rated "Likely Effective" for Coenzyme Q10 deficiency.
  • Also on file: Chromium is rated "Possibly Effective" for Diabetes.

The evidence for effectiveness varies by ingredient. Vitamin B6 is effective for sideroblastic anemia and B6 deficiency, and possibly effective for pregnancy-induced nausea.

Coenzyme Q10 is possibly effective for fibromyalgia, migraines, congestive heart failure, and diabetic nerve pain. Riboflavin has no established effectiveness ratings in our data.

Boron is likely effective for boron deficiency and possibly effective for vaginal yeast infections. L-carnitine is effective for L-carnitine deficiency and possibly effective for high cholesterol and congestive heart failure.

Chromium is likely effective for chromium deficiency and possibly effective for type 2 diabetes. Lipase lacks sufficient evidence to rate its effectiveness for the conditions it's used for.

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 8 of the 8 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 8 of 8.
  • General safety write-ups exist for 8 of 8.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most ingredients are generally well tolerated at typical doses. Vitamin B6 is safe at normal levels, but high doses over time can damage nerves (sensory neuropathy), especially above 1,000 mg daily.

Coenzyme Q10, riboflavin, and L-carnitine are generally well tolerated; common mild side effects include nausea, diarrhea, and gastrointestinal upset. Potassium can cause serious problems at high levels, including irregular heartbeats and dangerously low blood pressure, especially in people with kidney disease.

Chromium and boron are generally safe at typical doses. There is insufficient pregnancy and breastfeeding safety data for most ingredients; talk with your doctor or pharmacist before use if you are pregnant or nursing, especially since boron should be avoided in pregnancy and breastfeeding.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 6 of the 8 matched ingredients can interact with medications — Potassium, Chromium, Vitamin B6, Coenzyme Q10, Riboflavin, among others.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; Parkinson's medications.
  • For scale: 463 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking Isochrome, double-check with your pharmacist if you take blood pressure medications (antihypertensive drugs, ACE inhibitors, ARBs, or potassium-sparing diuretics), diabetes or insulin medications, blood thinners like warfarin or acenocoumarol, thyroid hormone (levothyroxine), seizure medications (phenobarbital or phenytoin), heart rhythm drugs like amiodarone, tetracycline antibiotics, or NSAIDs or aspirin. No interactions are documented for lipase among the ingredients we could check.

Each ingredient & the kinds of drugs it affects

For each ingredient in Isochrome 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.

Vitamin B65 drug types · 210 drugs

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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Unlikely Evidence D
Vitamin B6 full monograph & interactions

Coenzyme Q103 drug types · 198 drugs

Alkylating Agents

Coenzyme Q10 has antioxidant effects. Theoretically, this may reduce the activity of chemotherapy drugs that generate free radicals.
Theoretically, antioxidants such as coenzyme Q10 might protect tumor cells from chemotherapeutic agents that work by inducing oxidative stress, such as alkylating agents (e.g., cyclophosphamide) and radiation therapy. The clinical importance of this interaction is unknown.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Coenzyme Q10 is chemically similar to menaquinone and might have vitamin K-like procoagulant effects, which could decrease the effects of warfarin.
Concomitant use of coenzyme Q10 and warfarin might reduce the anticoagulant effects of warfarin. Four cases of decreased warfarin efficacy thought to be due to coenzyme Q10 have been reported. However, there is some preliminary clinical research that suggests coenzyme Q10 might not significantly decrease the effects of warfarin in patients who have a stable INR.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, coenzyme Q10 might have additive effects with antihypertensive drugs.
Some clinical research shows that coenzyme Q10 can significantly lower blood pressure, although other studies have shown conflicting results.

Likelihood Possible Evidence B
Coenzyme Q10 full monograph & interactions

Chromium5 drug types · 178 drugs

Antidiabetes Drugs

Theoretically, chromium may have additive effects with antidiabetic agents and increase the risk of hypoglycemia.
Some research shows that taking chromium might lower blood glucose levels, especially in patients with poorly controlled type 2 diabetes.

Likelihood Possible Evidence A
Insulin

Theoretically, concomitant use of chromium and insulin might increase the risk of hypoglycemia.
In clinical research, chromium has been shown to increase insulin sensitivity,

Likelihood Possible Evidence B
Levothyroxine (Synthroid, Others)

Chromium might bind levothyroxine in the intestinal tract and decrease levothyroxine absorption.
Clinical research in healthy volunteers shows that taking chromium picolinate 1000 mcg with levothyroxine 1 mg decreases serum levels of levothyroxine by 17% when compared to taking levothyroxine alone. Advise patients to take levothyroxine at least 30 minutes before or 3-4 hours after taking chromium.

Likelihood Probable Evidence B
Aspirin

Theoretically, aspirin might increase chromium absorption.
Animal research suggests that aspirin may increase chromium absorption and chromium levels in the blood.

Likelihood Possible Evidence D
Nonsteroidal Anti-Inflammatory Drugs (Nsaids)

NSAIDs might increase chromium levels in the body.
Drugs that are prostaglandin inhibitors, such as NSAIDs, seem to increase chromium absorption and retention.

Likelihood Possible Evidence D
Chromium full monograph & interactions

Potassium3 drug types · 62 drugs

Ace Inhibitors (Aceis)

Using ACEIs with high doses of potassium increases the risk of hyperkalemia.
ACEIs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Angiotensin Receptor Blockers (Arbs)

Using ARBs with high doses of potassium increases the risk of hyperkalemia.
ARBs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Potassium-Sparing Diuretics

Concomitant use increases the risk of hyperkalemia.
Using potassium-sparing diuretics with potassium supplements increases the risk of hyperkalemia.

Likelihood Likely Evidence C
Potassium full monograph & interactions

Riboflavin1 drug type · 20 drugs

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.

Likelihood Possible Evidence D
Riboflavin full monograph & interactions

L-Carnitine-L-Tartrate3 drug types · 19 drugs

Acenocoumarol (Sintrom)

Theoretically, L-carnitine might increase the anticoagulant effects of acenocoumarol.
L-carnitine might enhance the anticoagulant effects of acenocoumarol, an oral anticoagulant similar to warfarin, but shorter-acting. There are at least two case reports of INR elevation with concomitant use. In one case, a 33-year-old male with a previously stable INR had an elevated INR of 4.65 after L-carnitine was started and continued for 10 weeks. INR normalized after discontinuation of the L-carnitine-containing product.

Likelihood Possible Evidence D
Thyroid Hormone

Theoretically, L-carnitine might decrease the effectiveness of thyroid hormone replacement.
L-carnitine appears to act as a peripheral thyroid hormone antagonist by inhibiting entry of thyroid hormone into the nucleus of cells. Taking L-carnitine also seems to diminish some of the symptoms of hyperthyroidism.

Likelihood Probable Evidence B
Warfarin (Coumadin)

Theoretically, L-carnitine might increase the anticoagulant effects of warfarin.
L-carnitine might increase the anticoagulant effects of acenocoumarol, a shorter-acting oral anticoagulant similar to warfarin. There is not enough information to know whether this interaction occurs with L-carnitine and warfarin.

Isochrome by Isotonix: Common Questions

Does Isochrome by Isotonix interact with any medications?
Yes. Based on its ingredients, Isochrome has a known interaction with 463 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Isochrome contains 8 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is Isochrome safe to take if I'm on blood pressure medication?
Several ingredients in Isochrome—vitamin B6, coenzyme Q10, and potassium—may interact with blood pressure drugs. Vitamin B6 and coenzyme Q10 can theoretically add to the blood-pressure-lowering effect, while potassium poses a specific risk of dangerously high potassium levels with certain medications. Please check your exact medications with the tool on this page or talk to your pharmacist before starting.
Can I take Isochrome while pregnant or breastfeeding?
Safety data is limited for most ingredients during pregnancy and breastfeeding. Boron should be avoided during pregnancy and breastfeeding. Riboflavin is considered likely safe in pregnancy at recommended amounts, and potassium from diet is fine during pregnancy. For all other ingredients and any high-dose use, talk with your doctor or pharmacist—they can give you personalized advice based on your situation.
What are the most common side effects of Isochrome?
The most common side effects are gastrointestinal: nausea, diarrhea, abdominal pain, heartburn, and loss of appetite. Some people report headache or mood changes. Riboflavin can cause bright yellow urine at higher doses. Most side effects are mild and related to the digestive ingredients.
Is Isochrome effective for boosting energy?
The product contains several ingredients that support energy production—vitamin B6, riboflavin, coenzyme Q10, and L-carnitine are all involved in cellular energy. However, the evidence for their effectiveness as supplements for energy is not all equally strong in our data, and the amount of each ingredient in this formulation matters. Results vary from person to person.
Can I take Isochrome if I'm on a blood thinner like warfarin?
Isochrome contains two ingredients—coenzyme Q10 and L-carnitine—that may interact with warfarin or similar blood thinners. Coenzyme Q10 may decrease warfarin's effectiveness, while L-carnitine may increase it. Do not start this supplement without checking with your pharmacist first—your blood thinner may need to be monitored or adjusted.
Does Isochrome contain any fillers or inactive ingredients?
Yes, Isochrome contains inactive ingredients including fructose, citric acid, apple fiber, silicon dioxide, flavorings, and others. These are common excipients used to form the powder and improve taste.
