Which is the best immune-booster tea?

When it comes to staying healthy, supporting your immune system is a wise move. At all times of the year, viruses and germs can quickly lead to the cold, flu, or a host of other illnesses. In addition to common best practices (such as hand washing and physical distancing), immune-boosting teas proactively prevent sickness with all-natural ingredients.

Knowing which immune booster tea has the best ingredients and flavor can save time and money, and deliver the best results. Yogi Echinacea Immune Support is our top pick because it has a pleasant mint flavor, it is USDA-certified organic and it uses a powerful blend of herbs to boost the immune system.

What to know before you buy an immune-booster tea


No two immune-boosting drinks are made the same. This is also true when it comes to immune-booster tea. Common ingredients include elderberry, peppermint leaf, ascorbic acid (vitamin C), echinacea, yarrow flower, ginger, and lemon. Each tea can have a varying list of ingredients, so read the label before purchasing. Those who have sensitivities, allergies, or who are taking medication should be extra mindful of what is in their chosen immune-boosting tea.


It is fairly common for immune-boosting teas to contain flavors that are relatively strong. Peppermint, spearmint, ginger, and other potent herbs can be off-putting to some individuals. However, there are quite a few teas created to have mild flavors. When looking for a go-to tea, ensure the taste profile sounds appealing to you.


Immune booster teas can be awarded almost every kind of food and beverage certification available. This includes USDA organic certification, Non-GMO Project verification, and kosher certification. Teas also can be labeled as gluten-free, vegan, and sustainable. If there are specific certifications that are important to you, check for these on the box or in the product description.

What to look for in a quality immune-booster tea

All-natural ingredients

Highly-rated tea brands do not put artificial ingredients in their immune-boosting blends. Be aware that there are some companies that manufacture teas with artificial sweeteners and other chemicals. Teas containing artificial ingredients are often of lower quality and should be avoided.

Multiple immune-boosting ingredients

Top immune-booster teas combine a variety of ingredients shown to support the immune system. Blends that strategically combine herbs for this purpose often deliver the best results. Look for teas that list two or more primary immune-boosting ingredients.


For some individuals, caffeine can produce adverse effects in low quantities. According to MedlinePlus, excess caffeine consumption can lead to dehydration, headaches, dizziness, and insomnia. All of these side effects are counterproductive to boosting the immune system and preventing illness. This is why it is essential to purchase a tea blend that is caffeine-free.

Vitamin C

For decades, vitamin C has been recognized as a powerful ally of the immune system. Quality immune-booster teas often add vitamin C — or ingredients containing vitamin C — to further elevate the blend’s capabilities.

How much you can expect to spend on an immune-booster tea

One box of immune-boosting tea containing 16 bags typically costs $3-$6.
