The typical diet is deficient in nutrients and high in cholesterol and preservatives.
You may consume fruits and vegetables but that doesn’t mean that you’re getting all the necessary nutrients.

Furthermore, more nutritions are destroyed by food processing, storing and cooking.
To make things worse, stress can weaken your immune system which makes you more susceptible to microorganisms. Resulting in countless health complications.
Also, as you get older your nutrition requirements increase and you may experience declining levels in:

How much is enough?

Taking a high-quality supplement provides you with the peace of mind that you will not be deficient in essential nutrients.
