Vitamins and minerals are essential in boosting the immune system and maintaining a healthy body and mind.
Some of the most common deficiencies worldwide are vitamins A, D, B12, and minerals like zinc, iron, and iodine.
According to a global nutrition report, around 2 billion people suffer from at least one vitamin or mineral deficiency.
Around 1 billion people suffer from vitamin D deficiency.[source]
According to the world health organization, around 33% of the woman from 15-49 years old and 42% of children 6-59 months are anemic.
Vitamins A deficiency affects 29% of children 6-59 months in low and middle-income countries.
A nutrient deficiency may not directly cause a disease, but it weakens the body which makes you more vulnerable to a variety of diseases.
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.
Most non-organic foods grow in nutritionally deficient soil consequently giving a product that is deficient in vital vitamins and minerals.
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:
- Antioxidants(vitamin E, coenzyme Q10)
- Amino acids such as methionine and cysteine
How much is enough?
If you are like most people, you probably don’t eat a well-balanced diet every day. You maybe fall too often into the temptation of eating burgers, fries, sugar, or soft drinks.
When you see that you’re not taking the right amount of nutrients: You can change your diet or try a multivitamin supplement.
Taking a high-quality supplement provides you with the peace of mind that you will not be deficient in essential nutrients.
Some people may think that if some are good then more is better. This kind of thinking doesn’t apply to vitamins. If you consume large doses of vitamins for an extended period of time may cause serious side effects.
You can take a daily dose or in some cases, you may need to take a therapeutic dose that you use for a short period of time to prevent or manage the course of an illness.
There are fat and soluble vitamins.
Fat vitamins include vitamins A, D, E and K. Taking a large dose can build up in the body and can cause dangerous side effects.
Water-soluble vitamins include B-vitamins and C. They are stored in smaller amounts in the body and you should consume these vitamins more often.
You should always talk to your doctor or pharmacist before taking any kind of supplement.
Vitamin A or B-carotene
