Good Vitamin Supplement

Good Vitamin Supplement

A healthy immunity system plays a major role in defending and preventingdisease, illness, and stress, especially during the winter season. Winter is the main season that actually tests your immune system’s strength, though it is important that you keep your immunity levels strong throughout the year.

Reasons for Natural Weakness in Immune System during thewinter

As the winter season approaches, the natural defense system can be boosted, thereby assisting to keep off common winter diseases like flu, cold, and infections. This can be done by increasing the vitamins and antioxidants intake, thus strengthening the immunity system and assisting the body to fight against the bad viruses and bacteria that can cause illness. Here’s some advice as to how you can support your immune system in winter with a good vitamin supplement. So, let’s start by taking a look at the vitamins that you should be consuming in the run up to winter.

It’s Not About Consuming a Particular Vitamin!

It’s not that a single vitamin is essential for boosting the immune system of the body. A wide variety of vitamins as well as nutrients work together to fight the infections, though, these vitamins have a major role.

Benefits of Vitamin A

Vitamin A is the immune system’s defensive line and it keeps germs and infections from entering the bodies. It is responsible for keeping the mucous membranes lining the nose, mouth, and throat moist and soft so that they can trap the germs, ceasing their infiltration. Moreover, this vitamin helps in generating enzymes that look out for germs that manage to enter the body and kill them. People deficient in this vitamin can consume vitamin A rich food sources like carrot, sweet potatoes, liver, dried herbs, lettuce, dried apricots, and cantaloupe.

Vitamin B Boosts Up Your Energy Level

Vitamin B usually boosts the energy levels, thereby boosting the immunity system. These vitamins are available in the form of vitamin supplements, including B6, B12, and foliate. Studies have revealed that vitamin B6 can also strengthen the immunity system to a great extent.

Vitamin C Generates Antibodies and WBC

Vitamin C is equally important for enhancing the immunity system of the body. It assists the body to generate the white blood cells, antibodies, and anti-stress hormones, which are all needed for fighting the infections. This class of vitamin is a powerful antioxidant that kills fungi, bacteria, parasites, and viruses; it neutralizes the harmful bacteria and environmental toxins, while removing the toxic metals. To increase the vitamin C level in your body, you can consume food sources rich in this particular vitamin like guavas, dark leafy greens, cauliflower, broccoli, papayas, strawberries, kiwi, bell peppers, melons, tomatoes, and citrus fruits.

Role of Vitamin D

One of the most essential vitamins for immune functioning is vitamin D. Our bodies are made naturally in a way that they can increase the vitamin D reserves during the summer season so that it can be released slowly during the winter. We are moving near to deficiency levels in western communities and our immunity systems are not receiving the needed support as such. Thus, for several people, by improving their vitamin D levels before it gets very cold, we can make our bodies ready to prevent the illnesses and viruses that are common during the colder months. Few of the food sources rich in vitamin D include eggs, cod-liver oil, salmon, oysters, fish, soymilk, orange juice, and cereals. Vitamin D can also be obtained from safe exposure to sun.

How Does Vitamin E Help You?

Vitamin E also enhances the immunity system by generating an immune protein- interleukin-2 that kills viruses, bacteria, and even cancer cells. This particular protein is generated in the body when the body thinks that it has been invaded by infection-causing germs and it assists the white blood cells to increase and fight the diseases.

Few sources of food items rich in vitamin E include paprika, almonds, sunflower seeds, peanuts, and cooked spinach.

Zinc is another nutrient, which several people may find to be deficient in, particularly in the poorer and developing nations. Food sources for zinc include milk products, whole grains, oysters, red meat, and poultry. But, if your diet lacks zinc food sources, you may have to replace them with vitamins.

In a Nutshell

Now that you’ve understood all vitamins have one or the other role in boosting the immunity system, equal intake of all these vitamins is essential to lead a healthy life. By consuming natural food rich in vitamins, antioxidants, and other nutrients needed for a strong immunity system, you can get your body ready to fight off the infections during the winter. There are also vitamin supplements available in the health stores.

Joshua Jacksonis a strong supporter of green living, and staying healthy with natural supplements. He strongly recommends consumption of natural Vitamin Supplements during the winter season and avoiding the common diseases due to natural weakness caused in the immunity levels.

Vitamin A – description Wed, 20 Apr 2011 11:29:00 +0000 Healthy Eating

Vitamin A is an essential nutrient, which means that our bodies cannot create it and we must obtain it from our diets or supplements. Vitamin A is perhaps most well-known for its importance to our vision, but is also vital to other body systems and functions.

  1. Function of Vitamin A

    • The cells in our eyes that perceive light and color require vitamin A to function properly. In fact, one of the first signs of vitamin A deficiency is poor night vision, and if left untreated, vitamin A deficiency can lead to blindness. Vitamin A supports skin cells and the development of healthy bone tissue. Vitamin A is also a required nutrient for healthy immune system functioning. It protects and supports cell membranes to help fight infection and increases white blood cell activity.

    Vitamin A & Beta-carotene

    • In addition to vitamin A, there are dozens of other nutrients–called carotenoids–that are converted into vitamin A in the body and therefore have vitamin A “activity.” The best known of these carotenoids is beta-carotene. Beta-carotene is a non-toxic nutrient that is converted to vitamin A in the body as needed. If your body’s storage of vitamin A is adequate, beta-carotene will not be converted into vitamin A. Beta-carotene also has benefits of its own, acting as an antioxidant to protect cells in the body from free radical damage.

    Beta-Carotene as a Vitamin A Supplement

    • It is often advised to supplement with beta-carotene rather than vitamin A because beta-carotene does not have any toxic side effects in high doses. Vitamin A, on the other hand, if taken in large doses (more than 25,000 IU per day) for a long period of time, can cause liver damage, headaches and hair loss. If you do take excess amounts of beta-carotene, you may experience the development of a temporary orange coloration of your skin. This effect is harmless and will go away if you reduce your beta-carotene intake.

    Prevention of Vitamin A Deficiency

    • To ensure that you are obtaining enough vitamin A, make sure that you are taking 25,000 IU of beta-carotene daily, either on its own or as part of a daily multivitamin. If you are trying to prevent getting sick during cold and flu season, you can supplement with 5,000 IU of vitamin A daily (adults only), but do not continue this dose for more than a week without consulting your doctor and always consult your doctor before taking vitamin A if you are being monitored for any health condition.
      Those who live with Crohn’s disease, celiac disease or other malabsorption syndromes may develop a deficiency of vitamin A, as well as other nutrients. Deficiencies may not be severe enough to attract your attention, but may prevent you from being as healthy as you can be. Speak with your doctor about your need for additional nutrient supplementation if you are being treated or monitored for any chronic health condition. 

    Warning: Pregnancy and Vitamin A

    • High levels of vitamin A taken during pregnancy can increase the risk of birth defects, including heart and nervous system abnormalities, especially during the first trimester. It is therefore important to avoid direct vitamin A supplementation if there is the potential for you to become pregnant or if you are actively trying to conceive. Because vitamin A can be found in many processed foods, either limit your intake of vitamin A to less than 5,000 IU daily from supplements or take beta-carotene instead.
