Ok, No More Secrets – It’s our very own powerful Immune System. Boost it up and it will set us free.

Today, as the current world grabbles with the quickly evolving coronavirus with no known cure or vaccination, flu is the last thing we want to deal with. We surely can avoid a normal flu with the help of a strong immune system.

What is this Immune System?

Immune System is the strength of our body to fight against any invading pathology and thus avoiding any harm to it. Weakening of this defense mechanism is the root cause of recurrent infections and diseases. The solution is-

ENHANCING IMMUNITY- not as difficult as it sounds.

Good Sleep, Good nutritious diet, Regular exercise and minimal stress are some of the natural means to elevate immunity. Apart from these, a large number of Immune supplements are available in the markets, which are easy to consume and show positive results.

Here, we have listed a few very good tried and tested IMMUNE SYSTEM BOOSTERS –

#1. Optimunity Liposomal Vitamin C Supplements – The Best Immune Booster in 2020

  • Tops our list due to its strategic approach towards the immune system.

Well-Known fact:

Vitamin C is the best natural immune system booster known for its effectiveness against common cold and flu. It can’t be synthesized in the body and has to be supplied externally.

Almost every household has a granny encouraging the kids to eat citrus fruits (Oranges, gooseberries, lemon, etc.) rich in Vitamin C to strengthen their immunity. Since ages, Vitamin C is known for its antibiotic, antiviral, antihistaminic and antitoxin effects.

Optimunity - The best immune booster in 2020

Optimunity liposomal vitamin C is a popular Vitamin C supplement around the world owing to its efficacy and visible effects on health. It ensures: Optimum Dose + Maximum Absorption of Vitamin C.

How? By means of its

  • Rich Vitamin C content: contains 1500 mg of Vitamin C complex.
  • Unique Liposomal Mode of Absorption: This is the chief feature which raises the product above all other forms of Vitamin C available in the market.

Being water soluble, Vitamin C cannot be absorbed directly in the bloodstream limiting its bioavailability. Most of the consumed vitamin C thus is left unabsorbed and excreted out of the body.

Optimunity successfully freed Vitamin C from this restricted absorption. A liposome is a tiny, spherical bilayered drug delivery vehicle having a hollow inside and lipid soluble layer outside. In liposomal Vitamin C, the vitamin component is trapped inside the liposome. This liposome being lipid soluble carries the vitamin C to the target site and releases it there, thereby increasing the bioavailability of vitamin C.

Amazing Effects on human body:

1. Immune system booster:

During invasion by a pathogen, Vitamin C is known to enhance the production and functioning of white blood cells and antibodies, the ‘predominant warriors’ of immune system. Also, being a
potent antioxidant, Vitamin C protects the immune system from the oxidative stress generated by infections.

2. Stay Young Always:

  • Youthful Skin- Who doesn’t want to look young? Vitamin C is essential for production of collagen, a skin tightening protein. It thus enhances and retains skin quality and elasticity.
  • Young joints-Collagen is also needed to maintain the connective tissues like tendons, ligaments, muscles of joints.
  • Youth energy: Our body needs vitamin C to make L-carnitine, which helps you burn fat for energy.
  • Moods and Mental Health: Vitamin C helps in synthesis of mood enhancing neurotransmitters, dopamine, norepinephrine, and epinephrine.
  • Removes Fatigue and irritability.

3. Potent Antioxidant:
