HelloPharmacist Scorecard of SuperImmune+ by Quantum Health

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Sep 17, 2026

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 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

SuperImmune+ contains three active ingredients. L-lysine is an amino acid studied for cold sore prevention.

Olive leaf extract is derived from the olive plant. Astragalus root extract comes from an herb used in traditional medicine, thought to support immune function.

The product also contains inactive ingredients—hypromellose, microcrystalline cellulose, magnesium stearate, and water—that serve as capsule material and binders.

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: Herpes labialis (cold sores) — rated "Possibly Effective" (Lysine) (Natural Medicines).

The evidence for this product's ingredients is limited. L-lysine is possibly effective for cold sores, but the data for the other conditions listed—child growth, pressure ulcers, and diabetic foot ulcers—is insufficient to rate.

Olive leaf extract and astragalus root extract both lack reliable evidence for any of their claimed uses in our data, including support for allergies, infections, arthritis, or bone health. None of these ingredients are established to work for immune support specifically.

The evidence, ingredient by ingredient Lysine Olive Astragalus

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

L-lysine is generally well tolerated at typical doses, though high amounts may cause stomach upset, diarrhea, abdominal pain, or indigestion. Astragalus is generally well tolerated short-term in healthy adults, but quality safety data is limited; rarely, it has been associated with dizziness or palpitations.

Olive leaf extract appears well tolerated, with occasional headache or stomach discomfort reported. One patient reported acne after use, and olive tree pollen can trigger seasonal allergies in sensitive people.

Pregnancy and breastfeeding: Safety data for L-lysine and astragalus supplements during pregnancy and breastfeeding is not well studied. The facts advise against astragalus in both; for L-lysine and olive leaf extract, there isn't enough information to know either way.

Talk with your doctor or pharmacist before using this product if you're pregnant or breastfeeding.

Side effects, ingredient by ingredient Lysine Olive Astragalus

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?
  • 2 of the 3 matched ingredients can interact with medications — Lysine, Astragalus.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 209 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 start SuperImmune+, check with your doctor or pharmacist if you take immunosuppressant drugs, cyclophosphamide, lithium, antidiabetes medications, or 5-HT4 agonists. Astragalus may interfere with immunosuppressants and cyclophosphamide, increase lithium levels, or raise your risk of low blood sugar; L-lysine may reduce the effectiveness of 5-HT4 agonists.

These are Moderate or Minor interactions, but they're real and need a conversation with your own healthcare provider.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

SuperImmune+ may appeal to anyone looking for immune or cold-sore support, but the evidence for these uses is not established or is insufficient in our data. If you take immunosuppressants, lithium, diabetes medications, or 5-HT4 agonists, you'll need to check your exact medications with your doctor or pharmacist before starting this product—the interactions are real and could affect how your drugs work.

Pregnancy and breastfeeding also warrant a conversation with your healthcare provider.

Astragalus Root Extract4 drug types · 208 drugs

Antidiabetes Drugs

Theoretically, taking astragalus with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research in humans shows that astragalus might have hypoglycemic effects. Theoretically, taking astragalus, especially in combination with other hypoglycemic agents, might increase the risk of hypoglycemia.

Likelihood Probable Evidence A
Cyclophosphamide

Theoretically, astragalus might interfere with cyclophosphamide therapy.
Evidence regarding the effect of astragalus on immunosuppression caused by cyclophosphamide is conflicting. Some animal research suggests that astragalus reverses cyclophosphamide-induced immunosuppression. However, other animal research shows no effect.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, astragalus might interfere with immunosuppressive therapy.
Astragalus seems to stimulate immune function. Theoretically, taking astragalus might decrease the effects of immunosuppressive therapy.

Likelihood Possible Evidence D
Lithium

Theoretically, astragalus might increase levels and adverse effects of lithium.
Animal research suggests that astragalus has diuretic properties. Theoretically, due to this diuretic effect, astragalus might reduce excretion and increase levels of lithium.

Likelihood Probable Evidence D

L-Lysine1 drug type · 1 drug

5-Ht4 Agonists

Theoretically, lysine may reduce the effects of 5-HT4 agonists.
Animal research suggests that L-lysine is a partial serotonin receptor 4 (5-HT4) antagonist and inhibits diarrhea induced by the 5-HT4 agonist, 5-hydroxytryptophane.

SuperImmune+ by Quantum Health: Common Questions

Does SuperImmune+ by Quantum Health interact with any medications?
Yes. Based on its ingredients, SuperImmune+ has a known interaction with 209 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
SuperImmune+ contains 3 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.
Will this help me avoid cold sores or get over them faster?
L-lysine is possibly effective for cold sores based on available evidence, so it may help—but that's the only ingredient in this product with any established benefit for a specific condition. Olive leaf extract and astragalus lack reliable evidence for this use.
Is this safe to take if I'm pregnant or breastfeeding?
The facts advise against astragalus during pregnancy and breastfeeding because safety data is lacking. For L-lysine and olive leaf extract, there isn't enough information to know either way. Talk with your doctor or pharmacist for personalized advice—don't start this product without checking first.
What side effects should I watch for?
L-lysine may cause stomach upset, diarrhea, or indigestion, especially at high doses. Astragalus is usually well tolerated but has rarely been linked to dizziness or palpitations. Olive leaf extract occasionally causes headache or stomach discomfort. One person reported acne after use, and if you're allergic to olive pollen, this could trigger respiratory symptoms.
Can I take this with my antidiabetes medication?
Astragalus may lower blood sugar, so taking it with diabetes drugs could raise your risk of low blood sugar (hypoglycemia). You'll need to check with your doctor or pharmacist before adding this product—they can help you decide if it's safe or if you need to adjust anything.
How many active ingredients are in this product?
SuperImmune+ contains 3 active ingredients: L-lysine, olive leaf extract, and astragalus root extract. It also has inactive ingredients like microcrystalline cellulose and magnesium stearate that help form the capsule.
Does this work for boosting immunity?
The evidence for immune support from any of these ingredients is not established in our data. While astragalus is thought to stimulate immune function, reliable human studies confirming its benefit are lacking, so we can't say this product will boost your immunity.
