  • Description*

    NuMedica Seasonal Shield is an advanced, broad-spectrum nutritional formula that offers comprehensive support for seasonal environmental challenges.* This formula features select nutrients, including Vitamin C, Vitamin D3, and Zinc, chosen for their synergistic ability to support the body's immune response and provide protection.*

    Key Ingredients and Their Benefits

    NuMedica Seasonal Shield includes Quercetin, Bromelain, and Nettle extract, which help promote healthy mucus viscosity and support histamine.* Additionally, N-Acetyl L-Cysteine (NAC) is a unique form of the amino acid l-cysteine, known to support healthy tissue levels of glutathione (GSH).*

    Why Choose NuMedica Seasonal Shield?

    Do you suffer from sniffling, sneezing, and congestion when the seasons change? Many people do due to allergens such as animal dander, dust mites, molds, and pollen.

    Springtime can be especially challenging, with trees blooming and airborne allergens increasing. NuMedica Seasonal Shield offers advanced, broad-spectrum nutritional support to help alleviate or mitigate your symptoms by supporting your body's immune response.

    The Power of Vitamin C, D3, and Zinc

    Benefits of Vitamin C

    Vitamin C is a water-soluble vitamin essential for protecting against immune deficiencies, stress-induced immune weakness, and antioxidant protection. NuMedica Seasonal Shield provides 200 mg of Vitamin C per serving.

    Benefits of Vitamin D

    Vitamin D is a fat-soluble vitamin crucial for promoting healthy bones by aiding calcium absorption. It also stimulates insulin production to regulate the immune system. NuMedica Seasonal Shield provides 1,000 IU of Vitamin D per serving.

    Benefits of Zinc

    Zinc is an essential trace element for stimulating enzyme activity and regulating immune responses. NuMedica Seasonal Shield provides 25 mg of Zinc per serving.

    Additional Ingredients for Comprehensive Support

  • Ingredients
    Nutrient/Ingredient Amount % Daily ValueDV 1

    Four Capsules Contain:

    Vitamin C (as ascorbic acid)
    Vitamin C

    Vitamin C, also known as ascorbic acid, is a water-soluble nutrient found in some foods. In the body, it acts as an antioxidant, helping to protect cells from the damage caused by free radicals. Free radicals are compounds formed when our bodies convert the food we eat into energy. People are also exposed to free radicals in the environment from cigarette smoke, air pollution, and ultraviolet light from the sun.

    200 mg
    Vitamin D3 (as cholecalciferol) (1,000 IU)
    Vitamin D3

    Vitamin D is a nutrient you need for good health. It helps your body absorb calcium, one of the main building blocks for strong bones. Together with calcium, vitamin D helps protect you from developing osteoporosis, a disease that thins and weakens the bones and makes them more likely to break. Your body needs vitamin D for other functions too. Your muscles need it to move, and your nerves need it to carry messages between your brain and your body. Your immune system needs vitamin D to fight off invading bacteria and viruses.

    25 mcg
    Zinc (as zinc methionate)

    Zinc is found in cells throughout the body. It helps the immune system fight off invading bacteria and viruses. The body also needs zinc to make proteins and DNA, the genetic material in all cells. During pregnancy, infancy, and childhood, the body needs zinc to grow and develop properly. Zinc also helps wounds heal and is important for proper senses of taste and smell.

    25 mg

    Quercetin is a plant pigment (flavonoid). It is found in many plants and foods, such as red wine, onions, green tea, apples, berries, Ginkgo biloba, St. John's wort, American elder, and others. Buckwheat tea has a large amount of quercetin. Quercetin may antioxidant and anti-inflammatory support.


    500 mg
    Boswellia Extract (Boswellia serrata) (resin) (65% boswellic acids)
    Boswellia Extract

    Boswellia, or Indian frankincense, is a resin herbal extract from the boswellia tree, which natural medicine practices have used for centuries. Its anti-inflammatory effects mean that it may help with inflammatory conditions, such as rheumatoid arthritis, inflammatory bowel disease, and asthma.

    300 mg
    Nettle Leaf Extract (Urtica dioica) (4:1)
    Nettle Leaf Extract

    Urtica dioica has traditionally been used in the control of cardiovascular disorders especially hypertension. The leaf extract of Urtica dioica has been reported to improve glucose homeostasis in vivo. Nettle root could prevent some of the effects of prostatic hyperplasia.

    300 mg
    N-Acetyl L-Cysteine
    N-Acetyl L-Cysteine

    Cysteine is a semi-essential amino acid. It's considered semi-essential because your body can produce it from other amino acids, namely methionine and serine. It becomes essential only when the dietary intake of methionine and serine is low.

    Cysteine is found in most high-protein foods, such as chicken, turkey, yogurt, cheese, eggs, sunflower seeds and legumes.

    N-acetyl cysteine (NAC) is a supplement form of cysteine.

    Consuming adequate cysteine and NAC is important for a variety of health reasons - including replenishing the most powerful antioxidant in your body, glutathione. These amino acids also help with chronic respiratory conditions, fertility and brain health.

    250 mg
    Lemon Fruit Extract (Citrus x limon) (90% bioflavonoids)
    Lemon Fruit Extract

    Lemons, limes, grapefruits, and oranges are high in phytonutrients, such as carotenoids, flavonoids, and polyphenols. These nutrients are types of antioxidants and give the fruits their bright colors and strong scents. They can also help protect your body and prevent many health issues.

    222 mg
    Bromelain (2400 GDU/g)

    Bromelain is a protein-digesting enzyme mixture derived from the stem, fruit, and juice of the pineapple plant. It has a centuries-long history of being used to treat medical ailments, primarily throughout Central and South America.

    200 mg
    Grape Seed Extract (Vitis vinifera) (95% proanthocyanidins)
    Grape Seed Extract

    There is evidence that grape seed extract is beneficial for a number of cardiovascular conditions. Grape seed extract may help with a type of poor circulation (chronic venous insufficiency) and high cholesterol. Grape seed extract also reduces swelling caused by injury and helps with eye disease related to diabetes.

    20 mg
    Betaine (as betaine hydrochloride)

    Betaine works by preventing the build-up of an amino acid called homocysteine. This amino acid can harm blood vessels and contribute to heart disease, stroke, or circulation problems. Betaine is used to reduce homocysteine levels in people with a genetic condition called homocystinuria, in which the amino acid builds up in the body. Betaine is not a cure for homocysteinuria.

    During high pollen season, taking this daily (2 twice a day) seems to reduce the allergy effects. No antihistamine feelings, just milder symptoms. I was without it for several days and noticed a difference. I'll take it through the season.

    It works fantastic! Been using for a 3 years. Supplement also has the fastest shipping and always in stock for this product! This works better than any nasal spray or over the counter. More pleasant to take.

    It was suggested to me a few years ago to take this because I was the sole caretaker of my husband. For two years I never had the first cold or sinus infection. After my husband passed in 2020 I ran out.and didn't take any for about a month and of course came down with a.respiratory infection..i got another bottle and have taken it faithfully since and have not had another.

    I only provide a review when something is either very good or very bad. In this case, I'm happy to give the most positive review possible. I was suffering with terrible sore throats and congestion. My doctor recommended I use Seasonal Shield. It helped immediately. I couldn't recommend this product more. Ordering from was easy, and the price was in line with other suppliers. It came within days of my order (I was expect about a week).

    Finally! Allergy relief!

    Every spring I suffer with sinus headaches, itching eyes, runny nose, burning throat. I used to take steroid nasal spray, antihistamine and singulair with little improvement. Started Seasonal Shield on the advice of a integrative medicine NP friend and can't believe the results. All symptoms controlled and no RX's needed.
