Your body’s immune system needs to work a little harder during the winter season! Know why? It’s because cold weather can have an impact on immune system function for several reasons.
First, lower temperatures could have a negative impact on your immune system.[1] We typically spend more time indoors and thus cold and flu viruses spread easier,[2] while breathing cold air can narrow the blood vessels, preventing the white blood cells (immunity cells) from reaching the mucous membranes and therefore reducing the body’s ability to fight off invaders.
Give your immune system a boost with daily supplementation of Nutrifii™ Vináli®, a blend of vitamin C, citrus bioflavonoids and the extracts of grape seed, grape skin, Indian gooseberry (amla), acerola and green pepper.
Vitamin C contributes to immune defense by supporting various cellular functions of both the innate (first part of the body to detect invaders such as viruses and bacteria) and adaptive (second and specific line of defense that are called to action to “combat” the specific invader) immune system, by stimulating both the number and the activity of immunity cells.[3]
Vitamin C is also important for gene regulatory functions and has been shown to enhance the development and proliferation of B- and T- white blood cells, known as “helper” immune system cells.[4] A study indicated that supplementation of vitamin C caused a statistically significant increase in key proteins required for healthy immunity.[5] The extracts of Indian gooseberry, acerola and green pepper provide a wholefood source of vitamin C, which contribute to the immune-supporting effects of Vináli.
The combination of vitamin C and bioflavonoids, such as the grape seed extract proanthocyanidins and the citrus bioflavonoids in Vináli, are essential in any process related to immune function.[6] Studies have shown that bioflavonoids can improve the therapeutic action of vitamin C. The grape seed extract and citrus bioflavonoids can also help with improved mood — which is a great way to help fend off the “winter blues.”
So, what are you waiting for? Go on … get a Vináli boost today!
