Immune resilience is essential all year long. Whether it’s back-to-school season, the depths of winter, busy travel days, or the height of summer, your immune system is working tirelessly to defend against threats and keep your body well. Research shows that certain supplements can help maintain balance and support your wellness. Let’s take a closer look at some key vitamins and supplements that can help your immune system thrive year-round.
Key Takeaways:
- Vitamin C, D3, zinc, holy basil, and elderberry can each play a unique role in your immune defense regimen.
- Our supplements are formulated with highest quality ingredients to work in harmony with your body for effective immune support.*
Best Vitamin C for Immune Support
Vitamin C is often one of the first nutrients people think of when it comes to supplements with immune benefits
Why Vitamin C Matters
Many animals can synthesize their own vitamin C, but not us humans. We have to get our C from food and/or supplements. Yet vitamin C is crucial for life! Vitamin C, also called ascorbic acid, acts as a powerful antioxidant in the body, helping with everything from tissue healing to immune defense. For example, vitamin C supports neutrophils, which are specialized white blood cells that attack invaders in the body. There’s also evidence that regular vitamin C intake may reduce the duration (number of days of illness) and severity of a cold.

Our Vitamin C Supplements
New Chapter has multiple supplement options to help you get the vitamin C you need.
Fermented Vitamin C tablets

Each one-daily tablet is packed with 278% Daily Value of vitamin C that’s whole-food fermented, plus 8 complementary herbs including elderberry, maca, astragalus, ginger, and turmeric. Formulated for absorption and gentle even on an empty stomach.
Immune Defense Vitamin C+ gummies
Delicious citrus-flavored gummies deliver 139% Daily Value of vitamin C per serving (2 gummies), including ascorbic acid and from whole-food organic acerola cherry. For added immune support, this blend also delivers 5.5 milligrams of zinc per serving.*
Best Vitamin D3 for Immune Support
Vitamin D is most well-known for helping your body absorb calcium. However, it’s also a key player in healthy immune function. A 2023 review of research highlights that vitamin D influences at least 5 kinds of immune cells: neutrophils, macrophages (which consume invaders), immune system messenger cells, B cells that produce antibodies, and T cells that regulate immune response.
You can get vitamin D from a few foods, like fatty fish, beef liver, and mushrooms. As a public health effort, vitamin D is also added to common foods like fortified orange juice, milk, and breakfast cereal.
Our Vitamin D3 Supplements
When choosing a supplement, opt for Vitamin D3 (cholecalciferol), which research shows is more potent than the D2 form (ergocalciferol). New Chapter has got you covered with excellent quality D3 options!
Fermented Vitamin D3 tablets
One-daily tablets deliver 250% Daily Value (2000 IU, a clinically studied amount) of fermented, bioactive vitamin D3 for immune, heart, bone, and teeth support.* Crafted for absorption, USDA organic, and made with complementary organic turmeric and reishi mushroom.
Strength Support Vitamin D3+ gummies
Tasty mixed-berry flavored gummies give you 125% Daily Value (1000 IU) of bioactive D3 and are made with organic blue agave fiber† that replaces unnecessary extra sugar. USDA organic and gentle even on an empty stomach.
† Not a significant source of dietary fiber
Best Zinc for Immune Support
Zinc is a fascinating element that has been used as a supplement for at least 500 years. Its nutritional role in immune support has been researched since the 1960s.
Why Zinc Matters
Zinc is not stored in the human body so must be consumed daily in food and/or supplements. It can be found in meat and seafood, especially oysters. Zinc is also added to fortified breakfast cereals. Adequate zinc intake is essential because it plays a critical role in immune health. For example, research shows zinc helps signal the release of T cells and supports the proper development of B cells. Think of zinc as a cornerstone nutrient for your immune defense. You only need a small amount (8-12 milligrams per day, depending on age and life stage), but that amount is vital.

Our Zinc Supplements
New Chapter zinc tablets are expertly crafted with whole-food fermented zinc that’s gentle even on an empty stomach.
Fermented Zinc Complex tablets
This one-daily supplement is rich in zinc, delivering 136% Daily Value per serving. Bonus: Our product delivers fermented zinc which has been shown to be 1.6x better absorbed than the non-fermented zinc gluconate form. We make sure to also include 167% Daily Value of fermented copper. That’s because research shows a balanced copper-to-zinc ratio is important for overall health, especially when taking products that are rich in zinc.*
Magnesium + Selenium & Zinc tablets
This triple-mineral blend is crafted specifically for exercise recovery and is a good source of zinc (45% Daily Value). It delivers our signature blend of magnesium for healthy muscle function, selenium for antioxidant protection, and zinc to replenish your body’s levels after activity.*
All of our multi formulations (tablets, gummies & liquid) are a good source of zinc, so they can be your go-to for getting enough of this important nutrient every day! The amount of zinc in our multivitamins is carefully adjusted for your age and gender. For example, we have one-daily tablets for men and for women, with amounts of zinc tailored to support people 18+, 40+, and 55+.
Best Holy Basil for Immune Support
Immune-support supplements aren’t just vitamins and minerals. There are some heavy-hitters in the plant kingdom, too! For example, holy basil (also called tulsi or Ocimum sanctum) has been studied for its immune benefits.
Why Holy Basil Matters
Holy basil is an herbal adaptogen, meaning that it helps your body adapt to the effects of mental and physical stress. This rebalancing power has made holy basil a superstar in the healing traditions of India, including in Ayurveda where tulsi is sometimes called “The Incomparable One.” A review of the efficacy of holy basil in clinical studies found that it enhanced immune response in all 5 studies evaluated. Further research is needed on the benefits of this traditional superfood herb.

Elderberry, An Herbal Ally
Black elderberry (Sambucus nigra) is a traditional herbal remedy with a long history of use.
Why Elderberry Matters
Black elderberry has powerful antioxidant action from its dark, natural pigments known as flavonoids. A clinical study of over 300 commercial air travelers found that taking elderberry extract before and during their trip reduced cold symptoms and overall duration of colds. More research is needed on the health benefits of elderberry and its potential to support immune health.

Building Your Immune Supplement Routine
So, now what? Building an immune supplement routine starts with understanding your options. You can keep it simple by choosing one targeted supplement—like vitamin C for antioxidant support, vitamin D3 for immune balance, or zinc for cellular defense.* Or, if you prefer a more comprehensive approach, you can stack multiple nutrients to cover different aspects of immunity. (Hint: taking a multivitamin makes this super easy!) Add botanicals such as holy basil for yet another angle on immune support. Whatever you choose, ground your wellness routine in healthy habits like quality sleep, balanced nutrition, regular exercise, and stress management. If you have specific health needs or questions, check in with your healthcare provider.
