How to Choose Immune & Respiratory Supplements* 

Immune and respiratory supplements span a wide range of formulas—from targeted botanical extracts and antioxidant nutrients to sinus-specific and upper respiratory support products. Choosing the right formula starts with identifying your primary wellness goal and which aspect of immune and respiratory health you want to prioritize.* 

Targeted Botanical Immune Support vs. Broad-Spectrum Formulas* 

Some immune formulas are built around a single well-researched botanical—such as andrographis or elderberry—for focused, targeted support. Others combine multiple ingredients to address immune health more broadly, pairing botanicals with nutrients like zinc, selenium, or vitamin D3. If you have a specific wellness priority, a targeted single-ingredient formula may be the right starting point; if you’re looking for comprehensive daily coverage, a multi-ingredient formula may suit your routine better.* The best fit depends on your individual goals and the rest of your wellness routine. 

Respiratory and Sinus Support vs. Systemic Immune Support* 

Not all immune formulas address the same body systems. Formulas like Bronchial Clear™ and SinuCare™ are specifically designed to support bronchial and sinus comfort—they’re well suited for those prioritizing respiratory wellness. Formulas like Andrographis EP80™ Extra Strength, ViraPro®, and Propolis Extract EP300™ are oriented toward broader systemic immune support.* Understanding which area is most relevant to your needs will help you select the most appropriate formula from this category. 

Evidence-Backed Ingredients vs. Traditionally Used Botanicals* 

Terry Naturally’s immune and respiratory range includes ingredients supported by published scientific research—such as Andrographis EP80™, which is standardized to a precise level of andrographolides for optimal health.* The range also includes ingredients with long traditional histories of use, such as elderberry and propolis. When ingredient research matters to your decision, look for products that specify the extract form, standardization level, and type of research backing the key ingredient.  

Format and Delivery: Capsules, Chewables, Syrups, and Softgels 

Immune and respiratory supplements are available in multiple delivery formats—capsules, chewable tablets, syrups, enteric-coated softgels, and standard softgels. The format you choose can affect convenience, absorption, and suitability for different lifestyles.* Enteric-coated softgels (such as SinuCare™ Extra Strength) are designed to release their contents past the stomach for more targeted delivery, while syrups and chewables offer alternatives for those who prefer to avoid swallowing capsules. —The right choice is the one that best fits your daily routine and personal preference. 

Quality, Sourcing, and Ingredient Transparency 

When evaluating any immune or respiratory supplement, look for brands that are transparent about ingredient sourcing, standardization levels, and third-party testing. Terry Naturally products are rooted in rigorous quality standards, ensuring that what is on the label is what is in the product. Look for formulas featuring exclusive, research-backed ingredients—not generic commodity extracts. 

Frequently Asked Questions About Immune & Respiratory Supplements* 

What are immune and respiratory supplements used for?* 

Immune and respiratory supplements provide nutrients, botanicals, and bioactive compounds that support the body’s normal immune function and healthy respiratory system. Common uses include supporting healthy immune strength year-round, promoting comfortable sinus and bronchial function, and maintaining the body’s natural defenses.*  

What makes Andrographis EP80™ different from standard andrographis products? 

Andrographis EP80 is a proprietary extract standardized to a precise level of andrographolides—the primary bioactive compounds in andrographis that support optimal health. Unlike generic andrographis root powder, EP80 has been used in published scientific research.

How do I choose between the SinuCare™ and SinuCare™ Extra Strength formulas?

What is propolis and how does it support immune health?* 

Propolis is a resinous substance produced by bees that has a long traditional history and has been studied in published research for its role in supporting healthy immune function. Terry Naturally’s Propolis Extract EP300™ provides a standardized, concentrated propolis extract available in both capsule and chewable tablet formats. It is formulated for those looking to add a traditionally grounded, research-backed ingredient to their immune wellness routine.*
