Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 5 of its 5 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Vita-Kids Immune is a liquid formula with five active ingredients. Vitamin A supports vision and immune function.

Zinc is essential for immune cells and wound healing. Hesperidin Methyl Chalcone is a flavonoid derived from citrus.

Blueberry powder is a concentrated form of the fruit. We also couldn't check standardized Elderberry extract, as we have no interaction data for it.

The product contains seven inactive ingredients—water, glycerin, stevia, xanthan gum, citric acid, potassium sorbate, and natural grape flavor—that serve as the liquid base and preservative.

Does it work?

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
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: immune support.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence for this product's individual ingredients is mixed. Vitamin A is effective for vitamin A deficiency and possibly effective for several other conditions including oral leukoplakia, aging skin, measles, ulcerative colitis, and bronchopulmonary dysplasia.

Zinc is effective for zinc deficiency and likely effective for Wilson disease; it's possibly effective for acne, age-related macular degeneration, and diabetes. For Hesperidin Methyl Chalcone, the evidence doesn't support benefits for high cholesterol or obesity, and there's insufficient data on nonalcoholic fatty liver disease.

Blueberry powder shows insufficient evidence for cognitive decline, anxiety, athletic performance, heart disease, or high cholesterol, and possibly does not help with high blood pressure. Our data does not cover an effectiveness rating for standardized Elderberry extract.

The evidence, ingredient by ingredient Vitamin A Zinc Hesperidin Blueberry

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 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vitamin A is generally well tolerated at recommended doses, but high doses can build up in the body and become toxic—the safety data advises against high-dose supplements unless a clinician directs otherwise. Very high doses can rarely cause pseudotumor cerebri, liver damage, and other serious effects; children are more vulnerable to toxicity than adults.

Regarding pregnancy, vitamin A is rated possibly unsafe at high doses (especially as retinol) because of birth-defect risk, though recommended amounts are appropriate. Zinc is well tolerated below the upper limit of 40 mg daily; common side effects at higher doses include nausea, metallic taste, and diarrhea.

Long-term high doses carry theoretical concern for copper deficiency. Hesperidin Methyl Chalcone is generally well tolerated in food amounts and short-term use, but long-term safety data is limited.

Safety information for pregnancy is not sufficient; avoid high-dose supplements while pregnant or breastfeeding. Blueberry powder is generally well tolerated as a food; freeze-dried blueberries can cause constipation, diarrhea, nausea, or vomiting—in one trial, 26% of participants taking 50 grams daily stopped due to digestive upset.

There is insufficient data on concentrated blueberry extracts in pregnancy and breastfeeding.

Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 4 of the 4 matched ingredients can interact with medications — Vitamin A, Zinc, Blueberry, Hesperidin.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 1,060 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.

Check with your pharmacist if your child takes any of these: retinoid medications for acne or skin (Major risk); blood thinners like warfarin, other anticoagulants, or antiplatelet drugs; tetracycline or quinolone antibiotics; the heart drugs verapamil or diltiazem; blood pressure medications; HIV drugs including ritonavir or integrase inhibitors; diabetes medications; or the pain reliever flurbiprofen. Spacing zinc-containing products several hours away from most antibiotics can help reduce interactions.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.

This product is intended to support immune function with familiar nutrients and botanicals. If you take retinoid medications, blood thinners, tetracycline or quinolone antibiotics, heart drugs like verapamil or diltiazem, or HIV medications, you'll want to discuss this product with your pharmacist before starting—the interaction potential is real.

Children tolerate vitamin A toxicity less well than adults, so dosing matters. Talk to us or your doctor before adding this to your child's routine, especially if they're on any medications.

Hesperidin Methyl Chalcone7 drug types · 702 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, hesperidin may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Animal research suggests that hesperetin, a bioflavonoid aglycone derivative of hesperidin, may have antiplatelet activity.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, taking hesperidin with antihypertensive drugs might increase the risk of hypotension.
Some clinical and animal research shows that hesperidin can decrease blood pressure. However, other clinical research shows that hesperidin does not affect blood pressure.

Likelihood Possible Evidence D
Celiprolol (Celicard)

Theoretically, hesperidin may decrease the levels and clinical effects of celiprolol.
Animal research shows that concomitant use of hesperidin may reduce the plasma area under the curve of celiprolol by up to 75%. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, concomitant use with CNS depressants may cause additive sedative effects.
Animal studies show that hesperidin has sedative effects, due to opioid receptor activity and can increase sedation when used with diazepam. This effect has not been reported in humans.

Likelihood Possible Evidence D
Diltiazem (Cardizem, Others)

Theoretically, hesperidin may increase the levels and clinical effects of diltiazem.
Animal research suggests that hesperidin may enhance the bioavailability of diltiazem, increasing the plasma area under the curve of diltiazem by up to 65.3%. This effect has not been reported in humans.

Likelihood Possible Evidence D
P-Glycoprotein Substrates

Theoretically, hesperidin might inhibit P-glycoprotein-mediated drug efflux and potentially increase levels of drugs that are substrates of P-glycoprotein.
In vitro research shows that hesperidin can inhibit P-glycoprotein efflux. This effect has not been reported in humans.

Likelihood Possible Evidence D
Verapamil (Calan, Others)

Theoretically, hesperidin might increase the levels and clinical effects of verapamil.
Animal research suggests that hesperidin may enhance the bioavailability of verapamil, increasing the plasma area under the curve of verapamil by 96.8%. This effect has not been reported in humans

Likelihood Possible Evidence D
Hesperidin Methyl Chalcone full monograph & interactions

Vitamin A4 drug types · 387 drugs

Retinoids

Concomitant use of retinoids with vitamin A supplements might produce supratherapeutic vitamin A levels.
Retinoids, which are vitamin A derivatives, could have additive toxic effects when taken with vitamin A supplements.

Likelihood Probable Evidence D
Hepatotoxic Drugs

Theoretically, taking high doses of vitamin A in combination with other potentially hepatotoxic drugs might increase the risk of liver disease.
The tolerable upper intake level (UL) is the highest level of intake that is likely to pose no risk of adverse effects. Doses of vitamin A above the UL can cause hepatotoxicity, ranging from elevated liver enzymes to liver failure.

Likelihood Possible Evidence C
Tetracycline Antibiotics

Theoretically, taking tetracycline antibiotics with high doses of vitamin A can increase the risk of pseudotumor cerebri.
Benign intracranial hypertension (pseudotumor cerebri) can occur with tetracyclines and with acute or chronic vitamin A toxicity. Case reports suggest that taking tetracyclines and vitamin A concurrently can increase the risk of this condition. Avoid high doses of vitamin A in people taking tetracyclines chronically.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, high doses of vitamin A could increase the risk of bleeding with warfarin.
Vitamin A toxicity is associated with hemorrhage and hypoprothrombinemia, possibly due to vitamin K antagonism. Advise patients taking warfarin to avoid doses of vitamin A above the tolerable upper intake level of 10,000 IU/day for adults.

Likelihood Possible Evidence D
Vitamin A full monograph & interactions

Blueberry powder3 drug types · 88 drugs

Antidiabetes Drugs

Theoretically, blueberries or blueberry leaf extracts might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal and in vitro research suggests that blueberry and/or blueberry leaf extracts can lower blood glucose levels.

Likelihood Unlikely Evidence D
Buspirone (Buspar)

Theoretically, blueberry juice might increase blood levels of buspirone.
In vitro research shows that blueberry juice can inhibit the metabolism of buspirone, possibly by inhibiting cytochrome P450 3A (CYP3A) enzymes. However, pharmacokinetic research in humans shows that drinking 300 mL of blueberry juice 30 minutes before taking buspirone hydrochloride 10 mg does not significantly affect the concentration or clearance of buspirone.

Likelihood Unlikely Evidence B
Flurbiprofen (Ansaid, Others)

Theoretically, blueberry juice might increase blood levels of flurbiprofen.
In vitro research shows that blueberry juice can inhibit the metabolism of flurbiprofen, possibly by inhibiting cytochrome P450 2C9 (CYP2C9) enzymes. However, pharmacokinetic research in humans shows that drinking 300 mL of blueberry juice 30 minutes before taking flurbiprofen 100 mg does not significantly affect the concentration or clearance of flurbiprofen.

Likelihood Unlikely Evidence B
Blueberry powder full monograph & interactions

Zinc10 drug types · 67 drugs

Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)

Theoretically, zinc might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide should be taken at least 2 hours before or 6 hours after zinc containing products.

Likelihood Probable Evidence D
Cephalexin (Keflex)

Zinc might decrease cephalexin levels by chelating with cephalexin in the gut and preventing its absorption.
A pharmacokinetic study shows that zinc sulfate 250 mg taken concomitantly with cephalexin 500 mg decreases peak levels of cephalexin by 31% and reduces the exposure to cephalexin by 27%. Also, taking zinc sulfate 3 hours before cephalexin decreases peak levels of cephalexin by 11% and reduces the exposure to cephalexin by 18%. By decreasing cephalexin levels, zinc might increase the risk of treatment failure. This effect does not occur when zinc is taken 3 hours after the cephalexin dose. To avoid an interaction, advise patients take zinc sulfate 3 hours after taking cephalexin.

Likelihood Probable Evidence B
Cisplatin (Platinol-Aq)

Theoretically, zinc might interfere with the therapeutic effects of cisplatin.
Animal research suggests that zinc stimulates tumor cell production of the protein metallothionein, which binds and inactivates cisplatin. It is not known whether zinc supplements or high dietary zinc intake can cause clinically significant interference with cisplatin therapy. Cisplatin might also increase zinc excretion.

Likelihood Possible Evidence D
Integrase Inhibitors

Theoretically, taking zinc along with integrase inhibitors might decrease the levels and clinical effects of these drugs.
Zinc is a divalent cation. Pharmacokinetic studies have shown that other divalent cations such as calcium and iron can decrease blood levels of the integrase inhibitor dolutegravir through chelation.

Likelihood Possible Evidence D
Penicillamine (Cuprimine, Depen)

Zinc might reduce the levels and clinical effects of penicillamine.
By forming an insoluble complex with penicillamine, zinc interferes with penicillamine absorption and activity. Zinc supplements reduce the efficacy of low-dose penicillamine (0.5-1 gram/day), but do not seem to affect higher doses (1-2.75 gram/day), provided dosing times are separated. Advise patients to take zinc and penicillamine at least 2 hours apart.

Likelihood Probable Evidence B
Quinolone Antibiotics

Zinc can decrease the levels and clinical effects of quinolones antibiotics.
Quinolones form complexes with zinc in the gastrointestinal tract, reducing absorption of both the quinolone and zinc if taken at the same time. Advise patients to take these drugs at least 2 hours before, or 4-6 hours after, zinc supplements.

Likelihood Probable Evidence B
Ritonavir (Norvir)

Zinc modestly reduces levels of ritonavir.
Clinical research shows that zinc might reduce serum ritonavir levels by chelating with ritonavir in the gut and preventing its absorption. In patients with HIV, ritonavir is taken with atazanavir to prevent the metabolism and increase the effects of atazanavir. A pharmacokinetic study shows that, in patients being treated with atazanavir/ritonavir, co-administration of zinc sulfate (Solvazinc tablets) 125 mg as a single dose or as multiple daily doses for 2 weeks reduces plasma levels of ritonavir by about 16%. However, atazanavir levels still remains high enough to prevent HIV virus replication. Therefore, the decrease in ritonavir levels is not likely to be clinically significant.

Likelihood Probable Evidence B
Tetracycline Antibiotics

Zinc might reduce levels of tetracycline antibiotics.
Tetracyclines form complexes with zinc in the gastrointestinal tract, which can reduce absorption of both the tetracycline and zinc when taken at the same time. Taking zinc sulfate 200 mg with tetracycline reduces absorption of the antibiotic by 30% to 40%. Demeclocycline and minocycline cause a similar interaction. However, doxycycline does not seem to interact significantly with zinc. Advise patients to take tetracyclines at least 2 hours before, or 4-6 hours after, zinc supplements to avoid any interactions.

Likelihood Probable Evidence B
Amiloride (Midamor)

Amiloride can modestly reduce zinc excretion and increase zinc levels.
Clinical research shows that amiloride can reduce urinary zinc excretion, especially at doses of 10 mg per day or more. This zinc-sparing effect can help to counteract zinc losses caused by thiazide diuretics, but it is unlikely to cause zinc toxicity at usual amiloride doses. The other potassium-sparing diuretics, spironolactone (Aldactone) and triamterene (Dyrenium), do not seem to have a zinc-sparing effect.

Likelihood Probable Evidence B
Atazanavir (Reyataz)

Zinc modestly reduces levels of atazanavir, although this effect does not seem to be clinically significant.
Clinical research shows that zinc might decrease serum atazanavir levels by chelating with atazanavir in the gut and preventing its absorption. Although a single dose of zinc sulfate (Solvazinc tablets) 125 mg orally does not affect atazanavir concentrations in patients being treated with atazanavir/ritonavir, co-administration of zinc sulfate 125 mg daily for 2 weeks reduces plasma levels of atazanavir by about 22% in these patients. However, despite this decrease, atazanavir levels still remain at high enough concentrations for the prevention of HIV virus replication.

Vita-Kids Immune by Douglas Laboratories: Common Questions

Does Vita-Kids Immune by Douglas Laboratories interact with any medications?
Yes. Based on its ingredients, Vita-Kids Immune has a known interaction with 1,059 medications, including 9 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Vita-Kids Immune contains 5 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 for my child to take every day?
At recommended doses, the ingredients are generally well tolerated. However, vitamin A builds up in the body, so long-term use requires attention to total intake. Blueberry powder may cause digestive upset in some children. Chat with your pharmacist or pediatrician about what's right for your child's age and diet.
Can I give this if my child is on antibiotics?
That depends on which antibiotic. Zinc can reduce how well tetracycline and quinolone antibiotics work, and it may affect cephalexin too. If your child is on an antibiotic, check with your pharmacist before starting this product.
What's Hesperidin Methyl Chalcone, and why is it in here?
It's a flavonoid compound derived from citrus that's included for potential immune support. The evidence for its specific benefits is limited, and it's not a well-known household ingredient—your pharmacist can tell you more about what it does in this formula.
Does blueberry powder in this product cause the same digestive side effects as freeze-dried blueberries?
Freeze-dried blueberries can cause constipation, diarrhea, nausea, or vomiting—in one trial, 26% of participants taking 50 grams daily quit due to stomach upset. We don't have specific data on the blueberry powder form in this product, so watch for any digestive complaints.
Can I use this if I'm pregnant or breastfeeding?
Vitamin A at high doses is possibly unsafe in pregnancy due to birth-defect risk, though recommended amounts are appropriate. Hesperidin doesn't have enough safety information to recommend in pregnancy or while breastfeeding. Blueberries as food are fine, but concentrated supplements haven't been well studied. Talk with your doctor or pharmacist before using this product.
Why is there an ingredient (Elderberry) you couldn't check for interactions?
We don't hold interaction data on file for standardized Elderberry extract, so we can't tell you whether it interacts with medications. Your pharmacist can help you research that separately if needed.
