Is Your Immune System Ready for the Fall?

¿Está listo tu sistema inmunológico para el otoño?

Folks around the country are starting to pull out boots and coats, figure out which warm clothes still fit their kids, and empty out their yard’s sprinkler systems. Are you also prepping your immune system for everything coming its way?

A powerful team of natural immune boosters can help you and your family enjoy all the great parts of fall without being benched with illness.

Your immune-boosting starting lineup

Echinacea, vitamin C, and zinc are a trio known for helping prevent sickness and even shortening the duration of the common cold. (1)(2)

An analysis of 14 studies concluded that echinacea reduced a person’s odds of getting a cold by 58%. (3) In addition, a review of studies on vitamin C found that it reduced the duration of a cold by an average of 8% for adults and 18% for children. (4)

Zinc supports the immune system by developing and activating lymphocytes and neutrophils—white blood cells that attack foreign invaders. (5)(6) One study found that infants who received a weekly zinc supplement had 31% fewer incidents of pneumonia and 22% fewer incidents of diarrhea than the placebo group. (7)

Other MVPs for immune support

Research has shown that quercetin supports leukocytes, which are blood cells that fight infection and other diseases. (8) Other studies suggest that quercetin may be useful in treating autoimmune diseases by suppressing cells that erroneously attack healthy tissue. (9)

Vitamin D is critical for bone health, but did you know that vitamin D receptors are present in the body’s immune cells, meaning vitamin D helps your immune system defeat opponents. (10)

Ginseng also has immune-stimulating properties.(11) Ginseng has been shown to activate immune cells and decrease lung inflammation from a viral infection. (12)

While you’re raking leaves, planning holidays, and settling kids in their school routines, make sure you’re also stocking your cupboard with your immune-support squad. Have a great fall, without falling ill.

Let’s stay healthier, together,
