Capsules
Capsules offer precise dosing, longer shelf stability, and are typically more cost-effective per serving than gummies. They’re ideal for adults who have no trouble swallowing pills and want maximum ingredient potency without added sugars. Look for vegetarian capsules if that’s a concern. The main drawback is that some people find large capsules difficult to swallow, and children typically prefer other formats.
Gummies
Gummy supplements have transformed compliance for those who dislike swallowing pills. They typically taste pleasant and work well for both adults and children ages 4 and up. However, gummies often contain added sugars (usually 2-4 grams per serving), may have lower potency than capsules due to formulation constraints, and degrade faster in heat. Choose gummies made with pectin rather than gelatin for vegetarian options.
Powders
Powder formats like Emergen-C allow for customizable dosing and faster absorption since nutrients don’t need to dissolve from a capsule shell. They’re convenient for mixing into water or smoothies. Downsides include measuring inconvenience when traveling, potential for clumping in humidity, and often higher cost per serving than capsules.
Lozenges
Zinc lozenges are specifically designed for acute immune challenges rather than daily use. They dissolve slowly in the mouth, delivering zinc directly to throat tissues. Clinical research suggests ionic zinc from lozenges may be particularly effective when taken at the first sign of immune stress. However, they’re not suitable for long-term daily supplementation due to high zinc doses.
Individual Product Reviews
Viva Naturals Elderberry 5-in-1 — Best Overall
This comprehensive formula combines five research-backed immune ingredients in clinically meaningful doses, making it our top pick for daily immune support.
Viva Naturals has created an efficient all-in-one solution that eliminates the need for multiple bottles. Each two-capsule serving delivers 1000mg of concentrated elderberry extract (equivalent to 4000mg fresh fruit), 400mg vitamin C, 5000 IU vitamin D3, 10mg zinc, and 300mg ginger extract. The elderberry uses a 4:1 extraction ratio, meaning it’s significantly more concentrated than products using whole berry powder.
The vitamin D3 dose of 5000 IU is particularly notable—many combination products skimp on D3 with just 400-1000 IU, which may be insufficient for those with existing deficiencies. The inclusion of ginger adds digestive support and additional antioxidant properties. With 120 capsules per bottle providing a 60-day supply, this represents excellent value for a multi-ingredient formula. The capsules use bovine gelatin, so it’s not suitable for vegetarians.
Key Specifications:
- Elderberry extract: 1000mg (4:1 concentration)
- Vitamin C: 400mg
- Vitamin D3: 5000 IU
- Zinc: 10mg
- Ginger extract: 300mg
- Serving size: 2 capsules
- Servings per container: 60
Considerations: Contains bovine gelatin (not vegetarian). The zinc is in oxide form, which has lower bioavailability than picolinate or bisglycinate forms.

Considerations: Contains 4g sugar per serving. Lower vitamin C and zinc doses than capsule alternatives.
Garden of Life Organics Elderberry Gummies — Best Organic
These USDA Organic gummies deliver immune nutrients from whole food sources like guava and amla berry, with no synthetic vitamins or artificial ingredients.
For those who prioritize organic certification and whole food sourcing, Garden of Life’s formula stands apart. The zinc comes from organic guava leaves rather than synthetic mineral salts, while vitamin C is derived from organic amla berry. The elderberry is certified organic Sambucus nigra, and the formula includes organic echinacea and rosemary for additional botanical support.
What makes this product unique is the no-added-sugar approach—the gummies are sweetened only with organic fruit and dusted with organic rice meal and sunflower oil. This results in a less candy-like product that’s more aligned with clean eating principles. The formula is vegan, Non-GMO Project Verified, NSF Gluten-Free certified, and Kosher. The 120-count bottle provides a 30-day supply at the standard four-gummy serving.
Key Specifications:

- Organic echinacea and rosemary
- Serving size: 4 gummies
- Servings per container: 30
- Certifications: USDA Organic, Non-GMO Verified, Vegan, Kosher
Considerations: Requires 4 gummies per serving (more than competitors). Less sweet taste due to no added sugar may not appeal to everyone.
NOW Foods C-1000 Zinc Immune — Best Value
This straightforward formula delivers therapeutic doses of vitamin C and highly absorbable zinc at an unbeatable price point.
NOW Foods takes a no-frills approach with this formula, combining 1000mg vitamin C with 15mg zinc in the superior TRAACS zinc bisglycinate form. Clinical studies have demonstrated that zinc bisglycinate offers superior bioavailability compared to common forms like zinc oxide or zinc gluconate. This means more of the zinc you consume actually gets absorbed and utilized by your body.
The 180-capsule bottle provides a six-month supply at one capsule daily, making this among the most economical options for basic immune support. NOW Foods carries NPA A-rated GMP certification, meaning every aspect of manufacturing has been examined and verified. The formula is vegan, soy-free, and kosher.

Key Specifications:
- Vitamin C: 1000mg
- Zinc: 15mg (as TRAACS zinc bisglycinate)
- Serving size: 1 capsule
- Servings per container: 180
- Certifications: GMP Quality Assured, Vegan, Non-GMO, Kosher
Considerations: Does not include vitamin D or elderberry. Basic formula may not satisfy those seeking comprehensive support.
Thorne Vitamin D-5000 — Best Vitamin D
NSF Certified for Sport and trusted by over 100 professional sports teams, this pure vitamin D3 supplement delivers 5000 IU in a highly absorbable form.
Vitamin D deficiency is remarkably common, especially in northern latitudes and among those who spend most time indoors. Research has established vitamin D’s critical role in immune function—it helps regulate immune cell activity and inflammatory responses. Thorne’s D-5000 delivers vitamin D3 (cholecalciferol), which research shows is more potent and better absorbed than vitamin D2.
What sets Thorne apart is its commitment to purity and testing. The NSF Certified for Sport designation means this product is tested for compliance with label claims and screened for nearly 300 substances banned by major athletic organizations. Thorne is the #1 recommended clinical brand by healthcare practitioners and has partnered with Mayo Clinic on wellness research. The clean formula contains no gluten, dairy, soy, or common allergens.
Key Specifications:
- Vitamin D3: 5000 IU (125 mcg)
- Serving size: 1 capsule
- Servings per container: 60
- Certifications: NSF Certified for Sport, Third-party tested
Considerations: Single-ingredient supplement requires combining with other products for comprehensive support. Premium pricing reflects testing standards.
Thorne Zinc Picolinate 15mg — Best Zinc
This highly absorbable zinc picolinate formula from a trusted clinical brand provides optimal daily zinc support without excessive doses.
Zinc picolinate is widely considered the gold standard for zinc absorption. Picolinic acid is a natural mineral chelator produced by the body, and zinc bound to picolinic acid has demonstrated superior absorption compared to other zinc forms in clinical studies. Thorne’s 15mg dose hits the sweet spot—high enough to support immune function and fill dietary gaps, but not so high that it risks copper depletion or other issues associated with excessive zinc intake.
Like all Thorne products, this formula undergoes rigorous third-party testing and is manufactured to exceed industry standards. The clean formula is free from gluten, dairy, soy, and artificial additives. For those looking to add zinc to an existing supplement routine without getting excessive amounts from multi-ingredient formulas, this is the ideal choice.
Key Specifications:

Considerations: Single-ingredient supplement. Those with significant zinc deficiency may need higher doses under practitioner guidance.
Emergen-C Immune+ Triple Action Powder — Best Powder
This advanced formula goes beyond basic vitamin C with BetaVia algae extract designed to activate immune cells, plus vitamin D and zinc.
Emergen-C has been a household name in vitamin C supplementation for decades, and their Immune+ Triple Action represents the most advanced formula in their lineup. The “triple action” refers to activating immune cells with BetaVia (a beta-glucan from algae), supporting with antioxidants (vitamin C, zinc, manganese), and fortifying with vitamin D.
BetaVia is a patented ingredient sourced from Euglena gracilis algae that has been shown in studies to activate key immune cells and promote cell signaling. Combined with 1000mg vitamin C, B vitamins for energy support, and vitamin D, this powder dissolves into a pleasant fizzy drink. The raspberry and super orange flavors are made with natural ingredients. Each box contains 30 packets for on-the-go convenience.

- BetaVia: 200mg
- Vitamin D: included
- Zinc and Manganese: included
- B vitamins: included
- Serving size: 1 packet
- Servings per container: 30
Considerations: More expensive per serving than capsule alternatives. Contains added sugars for flavor.
BioSchwartz Immunity Boost — Multi-Ingredient Formula
This 17-ingredient formula casts a wide net with vitamins, minerals, herbs, and bee propolis for comprehensive immune and respiratory support.
BioSchwartz takes the kitchen-sink approach with this formula, combining vitamins A, C, and E with zinc, selenium, elderberry, echinacea, astragalus, goldenseal, bee propolis, garlic, oregano, and more. The bee propolis and goldenseal are specifically included to support healthy respiratory function, while the herbal defense blend adds garlic, oregano, and thyme.
Every batch is third-party tested for purity, potency, and quality. The formula is manufactured in a cGMP-certified facility and is free from GMOs, soy, gluten, milk, egg, wheat, peanuts, and shellfish. The 90-capsule bottle provides a 30-day supply at three capsules daily. This formula suits those who want maximum ingredient diversity in a single product.

Considerations: Requires 3 capsules per serving. Contains bee propolis (not suitable for those with bee allergies). Individual ingredient doses may be lower than single-ingredient supplements.
Life Extension Enhanced Zinc Lozenges — Best Lozenges
These specialized lozenges deliver ionic zinc acetate—the form shown in research to release 100% of its zinc as positively charged ions for acute immune support.
Unlike daily zinc supplements, these lozenges are specifically designed for use at the first sign of immune challenges. The zinc acetate form releases 100% of its zinc as positively charged ionic zinc, which research suggests may be more effective for acute immune support than other zinc forms. The large lozenge size is intentional—it allows the lozenge to dissolve slowly in the mouth, delivering zinc directly to throat and mouth tissues over an extended period.
Life Extension recommends dissolving one lozenge every two waking hours, not exceeding eight lozenges daily, and using for no more than three consecutive days. The peppermint flavor makes them pleasant to use. This is not a daily supplement but rather an acute-use product to keep on hand for immune challenges. The formula is vegetarian, non-GMO, and gluten-free.
Key Specifications:
- Zinc: 18.75mg (as zinc acetate)
- Form: Ionic zinc lozenges
- Flavor: Peppermint
- Serving size: 1 lozenge
- Servings per container: 30
- Usage: Acute support only, not for daily use
Considerations: Not designed for daily use. May cause nausea if taken on empty stomach. Large lozenge size may be challenging for some.
BioSchwartz Elderberry Capsules — Best Budget
This simple three-ingredient formula delivers elderberry, vitamin C, and highly absorbable zinc bisglycinate at an entry-level price point.
Sometimes less is more. BioSchwartz strips away complexity with this focused formula containing just 500mg Sambucus nigra elderberry, 120mg vitamin C, and 7mg zinc in the superior Albion zinc bisglycinate chelate form. The one-capsule-per-day serving makes it convenient and cost-effective, with each 60-capsule bottle lasting two months.
Despite the budget-friendly pricing, BioSchwartz maintains quality standards including third-party testing and manufacturing without GMOs, soy, gluten, or common allergens. The vegetarian capsules are easy to swallow. For those new to immune supplements or looking for basic support without spending a lot, this formula delivers the essentials.
Key Specifications:
- Elderberry: 500mg (Sambucus nigra fruit)
- Vitamin C: 120mg
- Zinc: 7mg (as Albion zinc bisglycinate chelate)
- Serving size: 1 capsule
- Servings per container: 60
Considerations: Does not include vitamin D. Lower doses than premium alternatives. No additional herbs or botanicals.
Buying Guide: What to Look for in Immune Support Supplements
Key Ingredients
Vitamin C: The most researched immune nutrient. Look for doses between 250-1000mg daily. Higher doses aren’t necessarily better, as absorption decreases significantly above 200mg. Ascorbic acid is the standard form; liposomal vitamin C may offer enhanced absorption.
Vitamin D3: Critical for immune regulation, especially if you have limited sun exposure. Look for vitamin D3 (cholecalciferol) rather than D2, as research shows D3 is more effective at raising blood levels. Doses of 1000-5000 IU are common; those with documented deficiency may need higher amounts under practitioner supervision.
Zinc: Supports immune cell function and inflammatory response. Zinc picolinate and zinc bisglycinate offer superior absorption compared to zinc oxide or zinc gluconate. Daily doses of 15-30mg are appropriate for maintenance; higher acute doses from lozenges may help during immune challenges.
Elderberry (Sambucus nigra): Traditionally used for immune support, elderberry contains anthocyanins with antioxidant properties. Look for standardized extracts that specify anthocyanin content or concentration ratios (like 4:1 or 64x).
Quality Indicators
Third-party testing: Independent verification ensures what’s on the label matches what’s in the bottle. Look for NSF, USP, ConsumerLab, or stated third-party testing.
GMP certification: Good Manufacturing Practice certification indicates quality control in production. NPA A-rated GMP is a particularly rigorous standard.
Clean labels: Fewer artificial additives, fillers, and allergens generally indicate higher quality. Look for products free from common allergens if you have sensitivities.
Red Flags to Avoid
Proprietary blends: When ingredient amounts are hidden in a “proprietary blend,” you can’t know if doses are therapeutic or just pixie dust.
Excessive doses: More isn’t always better. Zinc above 40mg daily long-term can cause copper deficiency. Vitamin C above 2000mg may cause digestive upset.
Unsubstantiated claims: Products claiming to “boost,” “cure,” or “prevent” disease are making illegal claims. Supplements can only claim to “support” bodily functions.
How to Take Immune Support Supplements
Timing
Vitamin C: Can be taken any time. Splitting doses (morning and evening) may improve absorption for doses above 500mg.
Vitamin D: Best taken with a meal containing fat, as D3 is fat-soluble. Morning or lunch is ideal since it may interfere with sleep if taken late.
Zinc: Take with food to minimize potential stomach upset. Avoid taking with high-phytate foods (whole grains, legumes) which can reduce absorption.
Elderberry: Can be taken any time. Most people find it convenient to take with their main meal.
Cycling Recommendations
Most immune supplements can be taken continuously during seasons when you need extra support. However, high-dose zinc (above 30mg daily) should generally be limited to short periods unless addressing a documented deficiency. Some practitioners recommend cycling elderberry—taking it for several weeks, then taking a break—though evidence for this practice is limited.
Format-Specific Instructions
Capsules: Swallow whole with water. Can be opened and mixed into food or smoothies if swallowing is difficult.
Gummies: Chew thoroughly before swallowing. Store in a cool, dry place to prevent melting.
Powders: Mix with 4-6 oz of water. Some people prefer cold water for a more refreshing drink.
Lozenges: Allow to dissolve completely in mouth over 20-30 minutes. Do not chew or swallow whole.
Research-Backed Benefits
Vitamin C
Vitamin C supports the production and function of white blood cells, particularly lymphocytes and phagocytes. Research suggests it may help reduce the duration of common colds, particularly in people under physical stress. A review published in the Cochrane Database found that regular vitamin C supplementation reduced cold duration by about 8% in adults. Vitamin C also supports the skin barrier, your body’s first line of defense against pathogens.
Vitamin D
Research has established vitamin D’s role in activating T cells, which are crucial for adaptive immunity. Studies have found associations between low vitamin D levels and increased susceptibility to respiratory infections. A meta-analysis published in the BMJ found that vitamin D supplementation reduced the risk of acute respiratory infections, with the greatest benefit in those who were deficient at baseline.
Zinc
Zinc is essential for the development and function of immune cells including neutrophils and natural killer cells. A Cochrane review found that zinc supplementation, particularly in lozenge form, may reduce the duration of cold symptoms when taken within 24 hours of onset. Zinc deficiency is associated with impaired immune function, making adequate intake particularly important.
Elderberry
Elderberry has been used traditionally for immune support for centuries. Modern research has identified anthocyanins and other polyphenols in elderberries with antioxidant properties. A systematic review published in BMC Complementary Medicine and Therapies found evidence suggesting elderberry may help reduce upper respiratory symptoms, though researchers called for more high-quality studies.
Safety Considerations
Potential Side Effects
Vitamin C: Generally well-tolerated. Doses above 2000mg may cause digestive upset, diarrhea, or nausea in some people. Those prone to kidney stones should consult a healthcare provider before high-dose supplementation.
Vitamin D: Toxicity is rare but possible with very high doses over extended periods. Symptoms of excess include nausea, weakness, and kidney problems. Those with certain conditions (sarcoidosis, some lymphomas) should be cautious.
Zinc: Can cause nausea when taken on an empty stomach. Long-term intake above 40mg daily may interfere with copper absorption, potentially leading to copper deficiency and associated neurological issues.
Elderberry: Generally well-tolerated. Raw or unripe elderberries contain cyanogenic glycosides and should never be consumed; only properly processed extracts are safe.
Who Should Avoid or Use Caution
Autoimmune conditions: Those with autoimmune diseases should consult their healthcare provider before taking immune-supporting supplements, as stimulating immune function may not be appropriate.
Organ transplant recipients: Immunosuppressive medications are intentionally reducing immune function; immune supplements may interfere with this treatment.
Pregnancy and nursing: Vitamin D and vitamin C in standard doses are generally considered safe. Consult a healthcare provider about elderberry and high-dose supplements.
Drug Interactions
Vitamin C may interact with certain chemotherapy drugs and statins. Vitamin D can interact with steroids, weight loss drugs, and some seizure medications. Zinc may reduce absorption of certain antibiotics (quinolones, tetracyclines) and should be taken several hours apart. Elderberry may theoretically interact with immunosuppressants. Always inform your healthcare provider about supplements you’re taking.
Frequently Asked Questions
Can supplements actually prevent getting sick?
No supplement can guarantee prevention of illness. However, research suggests that maintaining adequate levels of key nutrients like vitamin C, D, and zinc may support optimal immune function. Supplements are most beneficial for those with nutritional gaps or deficiencies.
Should I take immune supplements year-round or just seasonally?
This depends on individual factors. Vitamin D supplementation is often beneficial year-round for those with limited sun exposure. Basic vitamin C and zinc can be taken continuously. Some people prefer to increase elderberry during fall and winter months when immune challenges are more common.
Can I take multiple immune supplements together?
Yes, the ingredients in most immune supplements work through different mechanisms and can be combined safely. However, be aware of total doses—if you’re taking multiple products containing zinc, ensure total daily intake doesn’t exceed recommended upper limits (40mg for adults).
How quickly do immune supplements work?
Addressing nutrient deficiencies can take several weeks. Vitamin D levels typically take 6-8 weeks to stabilize with supplementation. Zinc lozenges for acute support may help within days when taken at first sign of symptoms. Consistency is more important than expecting immediate results.
Are gummies as effective as capsules?
Gummies can be effective but often contain lower doses of active ingredients due to formulation constraints. They also typically contain added sugars. For maximum potency, capsules are generally preferred. Gummies are a good option for those who won’t otherwise take supplements.
What’s the best form of zinc?
Zinc picolinate and zinc bisglycinate (glycinate) are considered the most bioavailable forms. Zinc acetate in lozenges releases ionic zinc effectively for acute support. Zinc oxide has lower absorption but is commonly used due to lower cost.
Can children take these supplements?
Many gummy supplements are formulated for children ages 4 and up. However, children’s dosing differs from adults. Look for products specifically designed for children, or consult with a pediatrician for appropriate recommendations.
Do I need a vitamin D test before supplementing?
A blood test (25-hydroxyvitamin D) can identify deficiency and help determine appropriate dosing. However, many healthcare providers consider moderate supplementation (1000-2000 IU daily) reasonable for most adults without testing, particularly in northern climates.
Are there any supplements I should take at the first sign of illness?
Zinc lozenges have the best evidence for reducing cold duration when started within 24 hours of symptom onset. Some people increase their vitamin C and elderberry intake at the first sign of immune challenges, though evidence is less robust.
What’s the difference between vitamin D2 and D3?
Vitamin D3 (cholecalciferol) is the form produced by your skin in response to sunlight and is found in animal sources. Vitamin D2 (ergocalciferol) comes from plant sources. Research consistently shows D3 is more potent and effective at raising blood vitamin D levels.
