What is multivitamins?

Multivitamins are supplements that contain a lot of vitamins and minerals and other active ingredients. *

Because there are no standards for multivitamins, the amount of nutrients and nutrients contained in each product varies.Products that contain minerals are also referred to as multivitamin minerals in particular.

There are many different forms of supplements, such as tablets, capsules, gummy, powders and syrups.

Most multivitamins are intake once or twice a day.The recommended intake is on the product label, so be sure to check.

Effects of Multivitamins

Thirteen vitamins and 16 different minerals are said to be important for health.They help the body’s enzymatic reaction, neurotransmission, and make up the body.

These are also nutrients necessary for the regeneration, maintenance, growth and control of the body’s cells.Multivitamins contain vitamins and minerals, but their types and quantities vary.In addition, herbs, amino acids, fatty acids, etc. may be added.Since multivitamin supplements are not regulated by the FDA, the amount of nutrients actually contained may be different from the display.*

Some products sometimes do not contain any of the nutrients listed.Multivitamins seem to be better off to buy reliable manufacturers.

It should be noted that multivitamins can be made from natural foods, but they may also be made artificially.

Effects of Multivitamins on Heart Disease

Heart disease is one of the leading causes of death worldwide.*

Many people seem to believe that multivitamins are effective for heart disease, but the evidence is mixed.

Some studies suggest that multivitamins reduce the risk of myocardial infarction and sudden death, while others say they are ineffective.*, *, *, *

Physicians’ Health Study II studied the effects of multivitamins on more than 14,000 middle-aged men over a period of more than 10 years.

The results showed that multivitamins were effective in heart disease, cerebral infarction, and mortality. *

A study of women found that taking multivitamins for three years reduced the mortality rate of heart disease by 35%.*

The Relationship between Multivitamins and Cancer

There are also various theories about the relationship between multivitamins and cancer.

Some studies claim that multivitamins reduce the risk of cancer, while others suggest that they increase the risk of cancer.*, *,*, *

In five multivitamins experiments involving 47,289 people, the risk of cancer in men was reduced by 31 percent and women reported that they were not effective. *

Two other studies have reported that taking multivitamins over the long term reduced the risk of cancer for both men and women. *, *

“The Physicians’ Health Study II” reports that men withno history of cancer take multivitamins for long periods of time every day, reducing the risk of cancer.However, the relationship to mortality is not sufficient in this study period.*

Other effects

Multivitamins are also studied for other effects, such as brain and eye health.

Improving brain function

Studies have reported that multivitamins have improved memory in the elderly. *, *, *

Multivitamin supplements also improve mood.There are reports that multivitamins, as well as the relationship between malnutrition and mood, have improved mood and eased symptoms of depression.*, *, *, *, *, *

However, there are studies that multivitamins have no effect on mood. *

Eye Health

Age-related macular degeneration is one of the causes of blindness.*

One study has reported that antioxidants vitamins and minerals may slow the progression of age-related macular degeneration.However, no clear evidence has been found.*, *

There are also studies that say that multivitamins reduce the risk of cataracts.*

Multivitamin Side Effects

Multivitamins should be careful with intake.

Some vitamins are dangerous to overdose.

Proper intake depends on solubility.

Solubility is parted into two groups:

  • Water-soluble: Water-soluble vitamins taken into excess are immediately discharged out of the body.
  • Fat-soluble: Fat-soluble min is less likely to be discharged out of the body, so it stays in the body for a long time.

Fat-soluble vitamins are vitamins A, D, E and K.Vitamins E and K are almost harmless, but vitamins Amazon and D are harmful when ingested in large quantities a day.

Pregnant women should be especially careful about overdosing of vitamin A.*

It is difficult to think that multivitamins can cause vitamin D to be consumed in large quantities, but be careful about overdoses of vitamin A.*, *, *

If you have a nutritious diet, taking multivitamins can be overnourished.

Smokers should not take multivitamins because there is a risk of lung disease caused by vitamin A and beta carotene. *

It is harmful when minerals are ingested in large quantities.For example, large amounts of iron are harmful.*, *

Another risk is the quality of multivitamin supplements.Poor quality multivitamins contain certain nutrients excessively and can harm the body.*

People who should use multivitamins

Multivitamins are not a supplement that anyone should take.For some, it can be rather harmful.

However, for the following people, it is thought that multivitamins are effective.

  • Elderly: Absorption of vitamin B12 decreases with age.The elderly tend to lack calcium and vitamin D.*, *
  • Vegans and vegetarians: Vitamin B12 is only contained in animal foods, so people who eat only vegetable foods run out of vitamin B12.In addition calcium, zinc, iron, vitamin D and omega-3 fatty acids are also prone to shortage. *, *
  • Multivitamins are also useful for people who are on a low-sugar diet, on a diet, or who have anorexia, who can’t get enough nutrition from food.


Multivitamins are not necessarily a healthy supplement.

In fact, there is no solid evidence that taking multivitamin supplements will make them healthier, and it can be dangerous for some people.

For some undernourished people, multivitamin supplements can be a good choice, but you need to be careful about overdoses.

In addition, multivitamins should not be used to supplement irregular eating habits.Balanced fresh whole foods bring much health in the long run.

Recommended Multivitamin Supplements

The above effects, after understanding the dangers, such as people on a diet, there is also a sense to take multivitamins and minerals.

In fact, I started dieting and started taking multivitamins about a month later, and i realized the effect.

If you feel that your intake nutrients are small in diet apps such as “Aken”, I think you may take a multivitamin diet.

For example, in my case, I can take some nutrition from food, so I make my intake half the recommended intake so that I don’t overdo it.
