In general, your immune system is made up of various tissues, cells and organs. It is a highly effective defense system against disease-causing microorganisms. However, there are times when it does not work; a germ wins the battle against your immune response, and you get sick. Can anything be done in this situation to improve the function of your immune system? What if you improve your diet? What if you took certain vitamins or dietary supplements? What if you changed your lifestyle in a way that you hoped would generate an ideal immune response?

The answers are below. In this guide, we shall review some of the best supplements for immune health and antioxidant protection (with a comparison of L-Citrulline vs L-Arginine) and dive into why it might be worth considering the addition of taurine in that combination. 

Key Vitamins and Minerals for Immune Support

There are nutrients deemed an absolute biological necessity for good immunity:

1. Vitamin D

Low doses of vitamin D have been linked with higher risks for respiratory infection. Since the main source is sunlight, most are deficient in it, especially in cold weather. Vitamin D as a supplement is a smart choice for immune protection and bone health in general.

2. Vitamin A

It is a fat-soluble vitamin that maintains the respiratory tract linings, which constitute our body's first line of defence against germs. Sweet potatoes, carrots, and greens are some of the sources. 

3. Vitamin E

Being antioxidant in nature, it prevents free radicals from damaging cells and maintains the balance of the immune system; seeds and nuts are good dietary sources. However, if you are not able to get enough from the diet, then supplements can be taken. 

4. Zinc and Selenium

Zinc helps immune cells to function properly, whereas selenium supports an anti-inflammatory antioxidant effect. Together, Zinc and Selenium provide a potent anti-invasion effect. 

5. Taurine: The Antioxidant Ally

We must add one more ingredient to the list: Taurine. It is an amino acid with some significant roles in the body, including support of immune health and nervous system function. Most of the time, your body is able to make enough taurine by itself; however, supplementation can also help provide you with enough taurine for your body's needs.

Herbal and Natural Therapies for Improved Defence

For long ages, herbs have been employed to maintain immune function. The scientific evidence that supports these old-age practices is being uncovered:

• Echinacea- Has evidence to reduce the intensity of colds.

• Elderberry- A type of antioxidant commonly taken for flu symptom relief.

• Garlic- Allicin is an immune stimulant and a natural antiseptic.

• Ginseng- It energizes and also decreases respiratory illness.

• Probiotics- As they are present in yogurt and in fermented food, they nourish the gut. Since 70% of our immune system resides in the gut, they have a gigantic role in keeping us protected. 

L-Citrulline vs L-Arginine: Which Is Best for Immune and Heart Health?

L-citrulline is usually thought of as a superior product to L-arginine because the body is able to absorb it better than L-arginine, and then turns it into L-arginine, which is then used for the production of nitric oxide (NO) which resulted in sustained and more effective blood flow, endurance, and muscle pumps than direct supplementation of L-arginine because of the speed with which amino acids get metabolized in the gut and liver limiting the results.

L-Citrulline vs L-Arginine

First impression would lead L-Arginine to appear the better option since it is immediately converted into nitric oxide. However, research proves that L-Citrulline increases blood arginine levels more effectively than arginine does. The reason lies in the fact that arginine gets quickly metabolized within the intestines, but citrulline is more stable with a longer half-life within the body.

• L-Arginine is quick but transitory.

• L-Citrulline is gradual but steady.

Together, these two make for the perfect combination: arginine gives an immediate kick, and citrulline offers a more delayed relief. For this reason, a good supplement will contain both.

If you are looking for a perfect immunity booster, then L-Citrulline with L-Arginine and Taurine by Ultra Herbs is the best option because it has an excellent combination of all three elements, which are vital for the human body.

Why Are Antioxidants Relevant to Immunity?

Free radicals are unstable molecules that not only damage your cells but also decrease your immunity. The antioxidants take care of dying them while you stay fine. They include Vitamin C and E, selenium, and taurine. They fight against oxidative stress so that your immune system is occupied battling actual foes, such as bacteria and viruses.

Final Thoughts

The immune system needs to be cared for at all times. Vitamins and minerals, herbs, and amino acids all get their turn in terms of health. Above all, though, we examined Citrulline vs Arginine but their combined effects work better on circulation, nutrient transport, and across the entire body. Taking them in the right proportion can lead to better immune health and a quality lifestyle.
