HelloPharmacist Scorecard of Phytonutrient by Altrum

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 11 active ingredients.
  • “Proprietary Antioxidant Vegetable Blend” is a proprietary blend — the label gives one combined amount (560 mg) without saying how much of each component you get.

Altrum Phytonutrient contains 11 active ingredients: tomato, kale, spinach, celery, broccoli sprout concentrate, beet extract, cauliflower, onion extract, a proprietary antioxidant vegetable blend, broccoli, and carrot. These are phytonutrient-rich vegetables and plant extracts chosen for their nutrient density and antioxidant content.

The product also includes inactive ingredients (microcrystalline cellulose, stearic acid, dicalcium phosphate, croscarmellose sodium, calcium stearate, and silicon dioxide) that serve as binders, flow agents, and tablet structure.

Does it work?

Moderate 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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Athletic performance — rated "Possibly Effective" (Beet) (Natural Medicines).
  • On file: Exercise-induced muscle soreness — rated "Possibly Effective" (Beet) (Natural Medicines).
  • On file: Scarring — rated "Possibly Effective" (Onion) (Natural Medicines).
  • On file: Colorectal cancer — rated "Possibly Effective" (Broccoli) (Natural Medicines).
  • On file: Vitamin A deficiency — rated "Possibly Effective" (Carrot) (Natural Medicines).

Evidence for these ingredients is mixed and mostly limited. Broccoli is rated possibly effective for colorectal cancer prevention.

Beet is possibly effective for athletic performance and exercise-induced muscle soreness. Carrot is possibly effective for vitamin A deficiency.

Tomato, kale, spinach, celery, cauliflower, and onion extract all lack sufficient reliable evidence to rate their effectiveness for the conditions studied — meaning the data we hold doesn't establish whether they work for those purposes. Many conditions listed have only "insufficient evidence" ratings, not proof they don't work, just that rigorous proof isn't yet available.

The evidence, ingredient by ingredient Tomato Kale Spinach Celery Broccoli Beet Cauliflower Onion

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 7 of the 9 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 9 of 9.
  • General safety write-ups exist for 9 of 9.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most of these vegetables are generally well tolerated as foods. Tomato, kale, spinach, broccoli, carrot, and cauliflower are rated likely safe in pregnancy and lactation as foods; however, concentrated supplements of tomato, broccoli, and beet lack robust safety data and should be used with caution or only under medical guidance.

Celery seed in medicinal amounts is rated likely unsafe in pregnancy and should be avoided; avoid medicinal celery supplements while breastfeeding due to insufficient data. Common side effects from concentrated forms include loose stools, diarrhea, abdominal pain, and cramping (broccoli sprout, beet, and onion extracts).

Tomato leaf and unripe green tomatoes contain tomatine, a compound that in excessive amounts can cause dizziness, headache, and mild spasms; the ripe fruit in normal food amounts is safe. Photosensitivity (increased sun sensitivity) has been reported with celery.

Allergic reactions — including oral allergy syndrome, throat swelling, hives, and rarely anaphylaxis — are possible with celery, onion, carrot, and broccoli in sensitive individuals.

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 9 matched ingredients can interact with medications — Beet, Spinach, Onion, Celery, Broccoli, among others.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 1,156 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 you take Altrum Phytonutrient, double-check with your doctor or pharmacist if you're on blood thinners like warfarin or antiplatelet drugs (aspirin, clopidogrel), diabetes medications, thyroid medication (levothyroxine), lithium, blood-pressure medications, or any drug metabolized by the cytochrome P450 system — especially CYP1A2, CYP2A6, CYP2E1, and CYP3A4 enzymes. If you're unsure whether your medication falls into any of these categories, ask your pharmacist to check your profile against this product.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Altrum Phytonutrient is a vegetable-based supplement best suited for people looking to add plant phytonutrients to their diet, with modest evidence for athletic performance and colorectal cancer. However, if you take blood thinners (especially warfarin), diabetes medications, thyroid medication, lithium, blood-pressure drugs, or drugs metabolized by your liver's cytochrome P450 system, you should check with your doctor or pharmacist before starting — this product has several documented interactions that may affect how your medications work.

Talk it over with your own healthcare provider to see if it's right for you.

Each ingredient & the kinds of drugs it affects

For each ingredient in Phytonutrient 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.

Beet extract3 drug types · 861 drugs

Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, beet might increase the levels of CYP3A4 substrates.
In vitro research suggests that betanin, the major pigment in beet, competitively inhibits CYP3A4 in a dose-dependent manner similarly to strong CYP3A4 inhibitor ketoconazole.

Likelihood Possible Evidence D
Antihypertensive Drugs

Beet and beetroot contain nitrates, which can cause vasodilation, potentially leading to lower blood pressure. However, a study published in the European Journal of Clinical Nutrition using concentrated beetroot juice found no significant impact on blood pressure or heart rate in different age groups. Other small clinical studies suggest that while beet consumption might transiently lower blood pressure due to vessel dilation, there's no consistent evidence of a lasting effect. Overall, the theoretical risk of reduced blood pressure due to beet's nitrate content exists, but studies generally indicate a low and temporary impact rather than a sustained decrease.

Likelihood Possible Evidence A
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, beet might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research suggests that beet induces CYP1A2 enzymes.

Likelihood Possible Evidence D
Beet extract full monograph & interactions

Celery8 drug types · 651 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, celery root might increase the risk of bleeding when taken with anticoagulant/antiplatelet drugs.
Celery root contains the constituents falcarinol and falcarindiol. Laboratory research suggests that these constituents can inhibit platelet aggregation. This effect has not been reported in humans.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, celery seed extract might have additive effects with antihypertensive drugs.
Clinical research suggests that taking celery seed extract may reduce daytime systolic blood pressure by about 12 mmHg compared to less than 1 mmHg with placebo.

Likelihood Probable Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, celery might increase levels of drugs metabolized by CYP1A2.
In vitro and animal research suggests that constituents of celery can inhibit CYP1A2. This effect has not been reported in humans.

Likelihood Possible Evidence D
Levothyroxine (Synthroid, Others)

Theoretically, celery seed might decrease the effects of levothyroxine.
Several cases of hypothyroidism with low T4 levels have been reported in people who were previously stabilized on levothyroxine and then started taking celery seed tablets. They presented with symptoms such as lethargy, bloating, and dry skin, and recovered when celery seed was stopped. However, celery stem and leaf has been associated with case reports of hyperthyroidism in patients with no pre-existing thyroid disorders.

Likelihood Possible Evidence D
Lithium

Theoretically, celery might reduce excretion and increase levels of lithium due to potential diuretic effects.
Celery is thought to have diuretic properties. However, this effect has not been confirmed in humans.

Likelihood Probable Evidence D
Venlafaxine (Effexor)

Theoretically, celery root extract might increase blood levels of venlafaxine.
There is one case report of a patient who experienced medication-induced bipolar disorder after beginning to take celery root extract 1000 mg daily along with venlafaxine 75 mg and St. John's wort 600 mg daily. Symptoms included confusion, speech abnormalities, manic affect, and visual hallucinations. The plasma level of venlafaxine was 476.8 ng/mL (normal range 195-400 ng/mL). It is theorized that celery root increased venlafaxine levels by inhibiting cytochrome P450 2D6.

Likelihood Possible Evidence D
Acetaminophen (Tylenol, Others)

Theoretically, celery juice might increase the effects and side effects of acetaminophen.
Animal research suggests that concomitant use of celery juice plus acetaminophen prolongs the effects of acetaminophen. This effect has been attributed to a decrease in hepatic cytochrome P450 activity. However, other animal research shows that pretreatment with celery root extract protects against acetaminophen-induced acute liver failure. These effects have not been reported in humans.

Likelihood Possible Evidence D
Photosensitizing Drugs

Theoretically, celery might increase the risk of photosensitivity reactions when taken with photosensitizing drugs.
Laboratory research shows that celery contains photosensitizing agents such as phenols and psoralens.

Likelihood Possible Evidence D
Celery full monograph & interactions

Onion extract5 drug types · 275 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, concomitant use of anticoagulant or antiplatelet drugs with onion might increase the risk of bleeding.
In vitro research shows that onion inhibits platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Concomitant use of antidiabetes drugs with onion may increase the risk of hypoglycemia.
Animal research and clinical research shows that taking onion can lower blood glucose levels. Monitor blood glucose levels closely.

Likelihood Possible Evidence B
Aspirin

Concomitant use of aspirin with onion may worsen onion allergy.
In one case report, a patient with a mild onion allergy reported worsening allergy, including swelling and severe urticaria, after taking aspirin.

Likelihood Probable Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Theoretically, taking onion might increase the levels and clinical effects of drugs metabolized by CYP2E1.
Animal research shows that taking onion powder inhibits CYP2E1. However, this interaction has not been reported in humans.

Likelihood Possible Evidence B
Lithium

Onion is thought to have diuretic properties. Theoretically, due to these potential diuretic effects, onion might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Likelihood Probable Evidence D
Onion extract full monograph & interactions

Broccoli sprout concentrate2 drug types · 187 drugs

Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, broccoli might reduce the levels and effects of drugs metabolized by CYP1A2.
Pharmacokinetic research in humans shows that eating 500 grams of fresh broccoli daily for 6-12 days can increase CYP1A2 activity by 10% to 200%. Induction of CYP1A2 activity by broccoli is attributed to its glucosinolate constituents.

Likelihood Possible Evidence B
Cytochrome P450 2A6 (Cyp2A6) Substrates

Theoretically, broccoli might reduce the levels and effects of drugs metabolized by CYP2A6.
Pharmacokinetic research in humans shows that eating 500 grams of broccoli daily for 6 days increases CYP2A6 activity by 135% to 550%. Induction of CYP2A6 activity is attributed to its glucosinolate constituents.

Likelihood Possible Evidence B
Broccoli sprout concentrate full monograph & interactions

Cauliflower1 drug type · 186 drugs

Cytochrome P450 1A2 (Cyp1A2) Substrates

Preliminary clinical evidence suggests that eating cruciferous vegetables, including broccoli, cauliflower, daikon radish sprouts, and cabbage, can increase cytochrome P450 1A2 (CYP1A2) activity by 14% to 27%. Theoretically, cauliflower might increase the clearance and decrease the effects of drugs metabolized by CYP1A2. Some drugs metabolized by CYP1A2 include clozapine (Clozaril), cyclobenzaprine (Flexeril), fluvoxamine (Luvox), haloperidol (Haldol), imipramine (Tofranil), mexiletine (Mexitil), olanzapine (Zyprexa), pentazocine (Talwin), propranolol (Inderal), tacrine (Cognex), theophylline, zileuton (Zyflo), zolmitriptan (Zomig), and others.

Likelihood Possible Evidence B
Cauliflower full monograph & interactions

Spinach2 drug types · 88 drugs

Antidiabetes Drugs

There are claims that spinach leaves have hypoglycemic effects. Evidence from clinical research suggests that consumption of a spinach-rich meal reduces post-meal blood glucose levels. Theoretically, spinach might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia. Monitor blood glucose levels closely. Dose adjustments might be necessary. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), and others.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Spinach contains vitamin K, which can interfere with the activity of warfarin.
In human research, although eating spinach with one meal does not result in coagulation test results outside the therapeutic range, daily consumption for one week necessitates dose adjustment of warfarin. Individuals using anticoagulants should consume a consistent daily amount of spinach to maintain the effect of anticoagulant therapy.

Phytonutrient by Altrum: Common Questions

Does Phytonutrient by Altrum interact with any medications?
Yes. Based on its ingredients, Phytonutrient has a known interaction with 1,155 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Phytonutrient contains 11 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 this safe to take if I'm pregnant or breastfeeding?
Tomato, kale, spinach, broccoli, and carrot as foods are rated likely safe during pregnancy and lactation. Celery seed in medicinal amounts is rated likely unsafe in pregnancy and should be avoided; avoid medicinal celery supplements while breastfeeding. Concentrated supplement forms of other vegetables lack enough safety data — talk with your doctor or pharmacist before taking concentrated forms while pregnant or nursing.
Can this help with cancer prevention?
Broccoli is rated possibly effective for colorectal cancer prevention. Tomato, kale, spinach, and others are listed for various cancers, but evidence is either insufficient or rated possibly ineffective for those uses — meaning proof isn't yet established. If cancer prevention is your goal, ask your doctor how this fits into your overall approach.
What's the main risk with this product and medications?
The biggest concern is spinach and warfarin (a blood thinner) — vitamin K in spinach can reduce how well warfarin works, and daily use may require dose adjustment. Celery interacts with a wide range of drugs, and broccoli can speed up clearance of certain medications. If you're on any prescription medication, check it against this product before starting.
Will this cause side effects?
Most common side effects from concentrated forms are loose stools, diarrhea, abdominal pain, and cramping — especially from broccoli sprouts and beet extract at higher doses. Celery can cause photosensitivity (sun sensitivity). Allergic reactions including throat itching, swelling, and rarely anaphylaxis are possible in sensitive individuals.
Does this product have fillers?
Yes, it contains inactive ingredients including microcrystalline cellulose, stearic acid, dicalcium phosphate, croscarmellose sodium, calcium stearate, and silicon dioxide — these are common binders and flow agents used in tablets.
Is it safe for someone with diabetes?
Spinach and onion extract may lower blood sugar and could increase the risk of low blood sugar (hypoglycemia) if you're already on diabetes medication. If you have diabetes and take medication, check with your doctor or pharmacist before starting this product.
