These free radicals tend to attack and eventually damage the cell wall of our skin, artery, eye, brain, etc and leads to poor immunity, aging, cardiovascular disease, cataract, Alzheimer disease, etc.

Vitamin C, phytochemicals present in guava act as a natural antioxidant which means it can combine with such harmful free radicals and convert them to harmless substances that can be excreted from your body. That is why Vitamin C is also called as “free radical scavengers”.

Therefore the adequate regular supply of vitamin C ensures boosting your immunity, prevent aging – wrinkles in the skin, hair fall, etc, keep your eyes, heart, and brain health.(5, 6)

2. Great for skin, teeth, gum and bone health – Synthesize collagen

Collagen? What is that? I am sure you have heard of this term too and again thanks to advertisements. Collagen is a protein which acts as cementing material for cells and tissues.

Vitamin C is one of the most important factors to ensure the formation of collagen in your body.

Therefore if you are deficient in vitamin C, you might have experienced swollen gum, bleeding gum with little pressure applied, red to purple tiny pinpoint spots on the skin, weak bone and teeth, delayed wound healing, scurvy, etc. Are you experiencing such a condition?

No matter how much of iron-rich foods you are eating daily until you ensure taking ample amount of vitamin C nothing can make the situation better. Yes, vitamin C helps to absorb iron in your body. Your uncontrolled hair fall, general weakness, breathlessness may be because of iron deficiency. Start eating well balanced natural foods along with guava without fail.
