5 of The Best Natural Immune Boosting Supplements For Adults








As we move into the time of year when colds, flu, and viruses run rampant. We spend more time indoors, consuming supplements rich with health benefits will help us trust our body’s innate immunity. It’s also important to remember that we will inevitably get sick. In truth, preventing sickness is not our main goal. Rather, it’s best to focus on helping our bodies navigate sickness with more ease. Chronic stress, environmental toxins, not getting adequate sleep, and a diet of inflammatory, processed foods weaken the human body’s defenses against many common illnesses. So here on this blog you’ll learn about 5 of the best natural immune boosting supplements for adults.

Illness can strike at any time, which is why it’s important to be prepared with a natural, holistic medicine cabinet. By intentionally preparing your medicine cabinet ahead of time, you can quickly and effectively support yourself during an illness. Taking the time to prepare your supplements allows you to have peace of mind and for any unexpected health issues. Getting back on your feet faster is the name of the game. And, if you’re a busy mama like me, having a holistic approach to wellness has been a game changer.

5 Natural Immune Boosting Supplements For Adults

This is a short list of potent vitamin supplements, tinctures, and real food blends that do the work to keep you healthy and strong and recover from sickness with a bit more ease. I never go anywhere without these five items!

Vitamin C

Pure Radiance Vitamin C: The powerful antioxidant properties of Vitamin C play an essential role in supporting a healthy immune system and optimal cellular functioning. Due to the stress of modern times and mineral-depleted soil, most of us, including our kids, need more Vitamin C. This is especially true at the start of the first symptoms and during active illness.

Vitamin C is a water-soluble vitamin and is used up more rapidly by the body during short moments or longer seasons of stress, so it is vital to replenish consistently. Look for a Vitamin C supplement made from whole foods—this ensures that the vitamins work synergistically to support your body and contain the right nutrients, enzymes, and bioflavonoids to be properly absorbed within the body. Synthetic Vitamin C, most of what you find, is highly processed and not doing your body much good.

Synthetic vs Food Based Supplements: Which Is Better?

For little ones, Vitamin C powder can be sprinkled atop apple sauce, added to a smoothie, or mixed in with water, formula, or milk.

Vitamin C plays a role in controlling infections and healing wounds and is a powerful antioxidant that can neutralize harmful free radicals and decrease the effects of environmental toxins.

Coated Silver

Coated Silver: A powerful antimicrobial that decreases viruses, fungus, yeast, and mold. It’s a beautiful defense against common pathogens. It encourages the body to navigate these sicknesses with a bit more ease. Helps us to align with the goal of assisting the body in its immune health rather than attempting to prevent illness altogether. It causes the cells and DNA of viruses, free radicals, and harmful invaders to break apart, decreasing the impact of the invasion of our body.

Coated Silver has a higher PPM (parts per million) than Colloidal Silver, so you only need a drop compared with a dropper full or teaspoon. It is also a non-reactive, much safer form of silver nanoparticles making it safe to take as daily support. And, of course, it’s including during pregnancy and with small children. It’s an amazing daily immune booster, and the amount can be increased during active sickness. You also can use Coated Silver in a Neti Pot or nebulizer or as a throat gargle to help decrease the duration of colds and other illnesses.


Aconite: This homeopathic remedy, sometimes called Aconitum or Wolf’s Bane, packs a punch. Its one you can give at FIRST symptoms of sickness. It’s very effective at decreasing symptoms if taken within the first 24 hours of the onset of symptoms. If you notice sneezing all of a sudden, a sore throat, or wake up with a cough or runny nose, take this homeopathic remedy right away. I always keep this remedy with me in my purse and when we travel in case we need it. It is helpful at nipping sickness quickly and decreasing the severity and duration.

This homeopathic remedy packs a punch. If taken within the first 24 hours of the onset of symptoms, can be very effective at decreasing symptoms. Ita game changer. Aconite has been used for centuries in Chinese medicine and was used in western medicine until the early 20th century.

Aconite, more commonly known as Wolfs Bane, can be used for treating heart disease, asthma, muscle spasms, and motion sickness. The powerful alkaloids that make this plant such a powerful healer can also be what make it a powerful poison. When used in small quantities at the onset of coughing, running nose, sore throat, or sneezing, it will drastically change the course of your infection – when taken within the first 24 hours. I always keep this remedy with me when we travel in case we need it!

Manuka Honey

Mānuka Honey [850+ MGO]: A spoonful of this medicinal-grade honey is my top daily immune booster for the whole family. Clinical studies have shown that this is not your average jar of honey! Mānuka Honey is made by bees who pollinate the Leptospermum Scoparium bush. They are a beautiful flowering plant native only to New Zealand. This honey is high in antibacterial properties and active enzymes and is effective against antibiotic-resistant strains. In addition to being beautifully supportive of both the immune and digestive systems (both are interconnected), Mānuka Honey can also be used topically for wound healing, burns, and cuts to help avoid bacterial infections making it the ultimate addition to your home care kit!

Rapid Rescue

Learn all about Rapid Rescue: A go-to potent defense at first symptoms of sickness or exposure that truly works! Rapid Rescue combines the powers of Elderberry, Echinacea, Propolis, and Oregano Oil which create a highly antibacterial and antiviral blend. I always keep a few bottles on hand and never travel without them because it works wonders!

This blend has the most beneficial effects, when taken intensely for the first 1 – 3 days of active sickness. But you can take up to 1 week. Rapid Rescue should not be taken during pregnancy.

During flu season, we are at risk of viral infections, and in recent years the chances of getting sick have increased. The best way to improve our immune function is to maintain a healthy diet with essential nutrients, get enough sleep, and have dietary supplements on hand.
