What the evidence says
Immune Support is a two-capsule daily formula with vitamins C, D3, E and B6, zinc, elderberry and echinacea extracts, citrus bioflavonoids and L-lysine. The vitamins and zinc have well-established roles in normal immune function, and two capsules supply 100% to 200% of the Daily Value of each. The herbal extracts have been studied with mixed results, at higher or better-defined doses, so no claim is made for them.
How it works
Immune cells and the body's barrier tissues need certain nutrients to work normally. Vitamin C supports barrier tissue and white blood cells. Vitamin D acts through receptors found on almost all immune cells. Zinc is needed to form and activate lymphocytes. Vitamin B6 supports lymphocyte production, and vitamin E is an antioxidant that helps keep cell membranes intact. Being short of any of these weakens immune function. Getting enough matters. Taking extra when you already get enough probably adds little, according to NIH. How elderberry and echinacea might act is not well defined.
The dose in this product
Two capsules provide vitamin C 180 mg, vitamin D3 40 mcg (1,600 IU), vitamin E 15 mg, vitamin B6 1.7 mg and zinc 11 mg. That is 100% to 200% of the Daily Value for each, at or above adult RDAs and below every adult upper limit.
How that compares with the studiesHide the comparison
The three benefits above rest on these nutrients. This product makes no claim about any illness. Trials that measured how often people fell ill used other doses or forms and are not a basis for any claim here: the vitamin C trials used 200 mg a day or more against 180 mg here, and the zinc studies used lozenges supplying 45 to 300 mg a day against 11 mg in a swallowed capsule.
Elderberry: the trials used 600 to 900 mg a day of a standardized extract, or a liquid extract, with mixed results. This label gives 500 mg of an extract with no stated standardization. Echinacea: a Cochrane review of 24 trials with 4,631 participants found that products differ greatly in species, plant part and preparation, and that no single trial of regular use showed a significant benefit.
The one large positive trial used 2,400 mg a day of one specific extract. This label gives 200 mg of an unspecified whole-plant extract. L-lysine (100 mg) and citrus bioflavonoids (100 mg): we found no human evidence of an immune effect at these amounts.
No claim is made for elderberry, echinacea, lysine or bioflavonoids.
- Moderate evidence
Vitamin C, vitamin D, vitamin B6 and zinc contribute to the normal function of the immune system
These are well-established nutrient functions. The NIH Office of Dietary Supplements describes a role for each in immune cells and barrier tissues, and EU regulators permit this wording for any product that is at least a source of the nutrient. Two capsules supply 100% to 200% of the Daily Value of each. The benefit is about getting enough: NIH notes that routine supplementation probably adds little in people who are not deficient. [1][2]
- Moderate evidence
Vitamin C, vitamin E and zinc help protect cells from oxidative stress
This is a well-established nutrient function. NIH describes vitamins C and E as antioxidants, with vitamin E helping to maintain cell membranes, and EU regulators permit this wording for vitamin C, vitamin E and zinc in products that are at least a source of them. Two capsules supply 200% of the Daily Value of vitamin C and 100% of vitamin E and zinc. It describes a normal function, not a measured health outcome. [1][2]
- Moderate evidence
Vitamin D helps the body absorb calcium and supports normal bones and muscles
This is a well-established nutrient function. NIH states that vitamin D promotes calcium absorption, is needed for bone growth and remodeling, and has a role in muscle function, and EU regulators permit matching wording. Two capsules supply 40 mcg (1,600 IU), above the adult RDA of 15 to 20 mcg and below the upper limit of 100 mcg. It is a reason not to run low, not a way to build bone or muscle: in 25,871 generally healthy adults who mostly had enough vitamin D, 50 mcg a day for about 5 years gave no measurable added benefit for bones, and trials on muscle strength have been inconsistent. [3][2]
Strong evidence: many human trials agree, at the amount in this product. Moderate evidence: human trials mostly agree, but they are small, short or mixed. Early evidence: a few small human studies or lab work. Promising, not proven.
Safety
Who it is for, and who should ask first
Do not use if
- You are allergic to plants in the daisy family, such as ragweed, daisies or sunflowers. Echinacea belongs to that family.
Good fit if
- Adults who want vitamins C, D, E and B6 and zinc in one daily product
- People whose diet may be short of these nutrients
- People who do not already take a separate vitamin D or zinc supplement
Ask your doctor first if
- You have an autoimmune condition, an immune deficiency or a white blood cell disorder. European regulators do not recommend echinacea in these cases
- You take medicines that suppress the immune system
- You have asthma, eczema or hay fever. Severe allergic reactions to echinacea are more of a risk
- You are pregnant or nursing. The safety of echinacea and elderberry in pregnancy is not known
- You have hemochromatosis (iron overload). Vitamin C above the RDA calls for caution
- You have high blood calcium, kidney disease or an overactive parathyroid gland, because of the vitamin D
- You have diabetes. Elderberry might affect insulin and blood sugar
- You are having chemotherapy or radiation therapy
- You are under 18 (label caution)
Interactions
- Medicines that suppress the immune system: echinacea and elderberry might reduce their effect.
- Quinolone and tetracycline antibiotics: zinc can block their absorption. Take the antibiotic at least 2 hours before or 4 to 6 hours after this product.
- Penicillamine: zinc can reduce its absorption. Take them at least 1 hour apart.
- Thiazide diuretics (water pills): with vitamin D they might raise blood calcium, and they increase zinc loss in urine.
- Statins: high vitamin D intakes might reduce the potency of atorvastatin, lovastatin and simvastatin. Orlistat and corticosteroids can lower vitamin D levels.
- Chemotherapy and radiation therapy: vitamins C and E might reduce their effectiveness. Ask your oncology team.
- Blood thinners and antiplatelet medicines: vitamin E supplements might interact with them. This product has 15 mg, the daily requirement, but tell your doctor.
- Levothyroxine: vitamin C taken at the same time might increase its absorption.
- Medicines broken down by liver enzymes, and caffeine: echinacea might change how the body handles them. The evidence is conflicting.
- Diabetes medicines: elderberry might affect insulin and blood sugar.
Possible side effects
- Stomach upset, nausea or diarrhea (the most common effects reported with echinacea)
- Skin rash. Allergic reactions to echinacea are uncommon but can be severe
- Trouble sleeping (reported with echinacea)
Upper limit
Adult tolerable upper intake levels from food and supplements combined are 2,000 mg for vitamin C, 100 mcg (4,000 IU) for vitamin D, 1,000 mg for vitamin E, 100 mg for vitamin B6 and 40 mg for zinc (NIH Office of Dietary Supplements). Two capsules provide 180 mg, 40 mcg, 15 mg, 1.7 mg and 11 mg. European regulators set a lower vitamin B6 limit of 12 mg a day in 2023.
No upper limit has been set for elderberry or echinacea. The European herbal monograph advises using echinacea for no more than 10 days at a time.
Combining with our other products
Vitamin D is the main risk. This product has 40 mcg (1,600 IU). Vitamin D3 adds 50 mcg, Ashwagandha Complex 20 mcg, Men's Multi 10 mcg and chocolate Plant Protein 2 mcg.
This product plus Vitamin D3 is 90 mcg a day before food is counted, close to the adult upper limit of 100 mcg (4,000 IU). Adding Men's Multi reaches the limit and adding Ashwagandha Complex passes it. The simple rule: take Vitamin D3 or Immune Support, not both, unless your doctor has advised that amount.
Zinc: with Men's Multi (15 mg) the total is 26 mg, under the 40 mg limit, and Men's Multi also supplies 2 mg of copper. Vitamin B6: this product (1.7 mg), Men's Multi (7.5 mg), Ashwagandha Complex (2.5 mg) and BCAA 2:1:1 (2.5 mg) total 14.2 mg, far below the US limit of 100 mg but above the 12 mg limit set by European regulators. Vitamin C and vitamin E with Men's Multi total 330 mg and 28.5 mg, well within limits.
Men's Multi also contains echinacea, and Mushroom Complex contains other immune-active ingredients. If a doctor has told you to avoid immune-stimulating supplements, that advice covers all three.

Answers
Questions people ask
Will this stop me getting sick?
No, and we do not claim that. This is a dietary supplement, not a medicine. It supplies vitamins and zinc that the immune system needs to work normally. Research on elderberry and echinacea is mixed and used different products and doses.
Can I take it with Vitamin D3 or Men's Multi?
Add up the vitamin D first. This product has 40 mcg (1,600 IU). With Vitamin D3 (50 mcg) you reach 90 mcg, close to the adult upper limit of 100 mcg, and adding Men's Multi (10 mcg) puts you at the limit. With Men's Multi alone the totals are 50 mcg of vitamin D and 26 mg of zinc, both within limits. Do not combine this product with Vitamin D3 unless your doctor has advised it.
Why do zinc supplements come with warnings about copper?
High zinc intake over weeks can block copper absorption. NIH puts that risk at 50 mg of zinc a day or more and sets the adult upper limit at 40 mg. This product has 11 mg, the RDA for men. Even with Men's Multi the total is 26 mg, and Men's Multi also supplies copper.
Can I take it every day all year?
The vitamins and zinc are at levels meant for daily use. Echinacea is less clear: NIH says it is likely safe for most adults for short periods, and the European herbal monograph limits its use to 10 days at a time. Long-term daily use has not been well studied. Ask your doctor if you plan to take it continuously.
Who should not take it?
Anyone allergic to plants in the daisy family, because of the echinacea. People with autoimmune conditions or on immune-suppressing medicines should ask their doctor first, as should anyone who is pregnant or nursing. The label says under-18s should consult a physician.
I heard elderberries can be poisonous. Is the extract safe?
Raw or unripe elderberries, and the leaves and stems, contain a substance that can release cyanide and cause nausea, vomiting and diarrhea. Cooking destroys it, and NIH says properly processed commercial products do not pose this concern. This product uses a fruit extract, not raw berries.
Is it vegetarian?
No. The capsule is made of gelatin.
When should I take it?
The label says two capsules a day with water. Taking them with a meal that contains some fat helps vitamin D absorption. If you take a quinolone or tetracycline antibiotic, take the antibiotic at least 2 hours before or 4 to 6 hours after this product, because of the zinc.
