Performance Lab Immune and Thorne Immune Activator are both one-capsule-a-day immune supplements, but they work from opposite ends. Performance Lab Immune pairs a heat-killed postbiotic with antioxidant and nutrient support, while Thorne feeds your gut bacteria with a prebiotic fiber and fruit polyphenols. For most shoppers, Performance Lab Immune is the better value: it costs about 30% less on a one-time purchase and roughly half as much on its four-bottle subscription, and it carries more ingredients with human research tied to immune outcomes. Thorne wins on brand reputation and sports certification.

Immune Support Ingredients: A Postbiotic Stack vs. a Prebiotic Pair
The first thing you notice is how different the labels look. Thorne Immune Activator lists two ingredients: 300 mg of Benicaros soluble carrot fiber and 250 mg of MitoHeal redcurrant and blackcurrant extract. That is a focused, minimalist formula built around gut health.
Performance Lab Immune packs six active ingredients into one capsule. The headliner is Immuse LC-Plasma, a heat-killed form of Lactococcus lactis delivering 100 billion cells per serving, according to Performance Lab. Alongside it you get 250 mg of Setria Glutathione, an antioxidant the body makes on its own, plus liposomal vitamin D3, vitamin C, selenium, and zinc. The vitamin C, selenium, and zinc come in Performance Lab’s NutriGenesis forms, which the brand designs for better absorption.
One note: the vitamin C (30 mg) and zinc (5 mg) doses here are modest. They round out the formula rather than serving as the main event. If you want high-dose vitamin C or zinc, you would add those separately, and Thorne does not include them either.
How Each Formula Supports Your Immune System
Think of these two products as different routes to the same destination.
Thorne takes the gut-first route. Its prebiotic fiber is food for the beneficial bacteria in your digestive tract, and Thorne points out that a large share of your immune cells live in and around the gut. The idea is that a well-fed microbiome helps your immune system stay ready.
Performance Lab takes the immune-cell route. Immuse LC-Plasma is studied for its ability to activate plasmacytoid dendritic cells, which act like scouts that alert other immune cells. Performance Lab says the full formula supports five immune cell types: those scouts, natural killer cells, killer T-cells, helper T-cells, and B-cells. The vitamin D3, selenium, zinc, and vitamin C round things out with nutrients your immune system relies on every day.
Research Behind the Key Immune Ingredients
This is where Performance Lab Immune pulls ahead. Performance Lab states that the Immuse ingredient has been tested in 7 clinical trials for efficacy and 2 for safety. You can check the published work yourself. One randomized, placebo-controlled trial followed 51 male university athletes taking 100 billion heat-killed LC-Plasma cells daily for 13 days. The group taking LC-Plasma logged fewer cumulative days of upper respiratory symptoms (39 days vs. 56 days for placebo) and fewer days of fatigue. A separate randomized trial on PubMed looked at the same bacterial strain and its effect on influenza-like illness and the body’s interferon response during winter.
The minerals have a solid foundation too. MedlinePlus explains that zinc is found in cells throughout the body and is needed for the immune system to work properly. The NIH Office of Dietary Supplements adds that your immune system needs certain vitamins and minerals to function well.
On the Thorne side, the carrot fiber ingredient has its own studies. Trade publications report a randomized, placebo-controlled study of 146 healthy people, with results showing growth of beneficial gut bacteria at a 300 mg daily serving. That is a real point in Thorne’s favor, though the findings center on gut bacteria rather than direct immune outcomes. For the MitoHeal currant extract, the research highlighted by its supplier focuses on skin and healthy aging, and we did not find human trials tied directly to immune function.
Price Per Day and Value Compared
Prices below were checked November, 2026, on each brand’s own website. Both products come in 30-capsule bottles with a one-capsule daily serving, so the math is simple.
- Thorne Immune Activator: $49.00 per bottle, or about $1.63 per day.
- Performance Lab Immune, one-time purchase: $34.00, or about $1.13 per day (roughly 31% less than Thorne).
- Performance Lab Immune, monthly subscription: $30.60, or about $1.02 per day.
- Performance Lab Immune, four-bottle subscription: $102.00 every four months, or about $0.85 per day (about 48% less than Thorne).
Over twelve bottles, that four-bottle plan costs about $306, compared with $588 for Thorne at list price. That is a difference of roughly $280 a year. Thorne may offer its own subscription or promotional discounts, so check its current checkout page before you decide.
Quality, Testing, and Certifications
The Thorne brand is widely used by practitioners and athletes, and Immune Activator carries the NSF Certified for Sport mark. According to Thorne, that mark means the product was tested against its label claims and screened for nearly 300 substances banned by major athletic organizations. If you compete in tested sports, that certification could be important.
Performance Lab states that Immune is made to Clean Label standards and third-party tested for purity and potency. The label is free of gluten, soy, dairy, synthetic additives, and caffeine, and the pullulan capsule makes it suitable for vegans. Performance Lab shows every ingredient dose with no proprietary blends, which makes the label easy to evaluate.
Who Should Choose Performance Lab Immune
Performance Lab Immune is a strong fit if you want:
- A lower cost per day, especially on a subscription.
- Ingredients with published human research tied to immune markers and symptoms.
- Vitamin D3, selenium, and zinc in the same capsule.
- A vegan-friendly formula with every dose listed.
If that sounds like you, take a look at Performance Lab Immune and compare the purchase options.
Who Should Choose Thorne Immune Activator
Thorne makes sense if you:
- Compete in drug-tested sports and need NSF Certified for Sport.
- Want a gut-first approach built on prebiotic fiber.
- Already take vitamin D, vitamin C, or zinc separately and want a formula that stays out of their way.
Can You Take Both Together?
The two formulas do not overlap in ingredients, so on paper they complement each other: one supports the gut environment, the other targets immune cell activity. Thorne lists no known adverse interactions for its product. Still, it is worth asking your doctor or pharmacist before combining supplements, particularly if you take medication.
Frequently Asked Questions
Is Performance Lab Immune better than Thorne Immune Activator?
For most people, Performance Lab Immune offers more value. It costs less per day, includes more ingredients, and features an ingredient with published human trials on immune markers. Thorne is the better pick if you need NSF Certified for Sport or prefer a prebiotic-only formula.
What is the difference between a postbiotic and a prebiotic?
A prebiotic is a fiber that feeds the beneficial bacteria already living in your gut. A postbiotic is a preparation of inactivated microorganisms. In Performance Lab Immune, the Immuse ingredient is a heat-killed bacterial strain, so it is shelf-stable and does not rely on live cultures.
How much cheaper is Performance Lab Immune than Thorne Immune Activator?
As of November, 2026, Performance Lab Immune costs $34.00 one time, compared with $49.00 for Thorne, about 31% less. On Performance Lab’s four-bottle subscription at $25.50 per bottle, it costs roughly half as much as Thorne’s list price.
How long does it take to notice results from an immune supplement?
Immune supplements work gradually and results vary from person to person. Thorne notes that supplements support long-term health over time, and Performance Lab recommends consistent daily use. Taking it consistently matters more than any single week.
Do these supplements contain vitamin C and zinc?
Performance Lab Immune contains 30 mg of vitamin C and 5 mg of zinc, along with vitamin D3 and selenium. Thorne Immune Activator contains neither. It is designed to build on foundational nutrients you may already take.
Final Verdict on Performance Lab Immune vs Thorne Immune Activator
If you want the most immune support for your money, Performance Lab Immune is the stronger choice. It delivers a broader formula, a postbiotic with published human research, and a price that drops to about half of Thorne’s on a subscription. Thorne Immune Activator is a quality, focused product that earns its place for athletes who need NSF certification and for people who want a gut-first approach. Whichever you choose, pair it with the basics: sleep, movement, and a varied diet. You can see current pricing and subscription options for Performance Lab Immune here.
