Research results show that supplements do not properly supplement nutrients and may increase the risk of death when overdose
Even if you know that a well-balanced diet is essential for good health, it is difficult to get a nutritious diet for all three, and many people say that they are replacing it with a supplement. However, it has been reported that not only no effect can be seen for supplements, but that overdose of certain nutrients in supplements may increase the mortality rate.

Vitamins from Food — Not Supplements — Linked with Longer Life
The research group that announced the results of the experiment that Sapri will not improve the risk of death is Fang Fang Zhang and others at Friedman's Graduate School of Nutrition Science Policy at Tufts University. The experiment was conducted as a prospective cohort study that tracked supplement consumption and mortality in approximately 27,000 Americans.
The survey spans more than 10 years from 1999 to 2010, with 3613 deaths, including 945 deaths due to cardiovascular disease such as heart disease and 805 deaths due to cancer during the period. When the research group analyzed the relationship between the mortality rate and the results of the questionnaire surveying diet and supplement intake status, it was confirmed that the people who were taking enough nutrition had a significantly lower risk of death. However, the improvement in the risk of death was limited to nutrition from food, and people who were supplementing with supplements had a high risk of death as in the case of malnutrition.
Furthermore, in contrast to those who were taking more than 1000 mg of calcium a day by supplements, the risk of cancer death was high, and there was no relationship between dietary calcium intake and cancer mortality risk. The result is
Mr. Zhang, who led the experiment, said, 'Even if supplements can feed on specific nutrients, if there is a lack of nutrients that supplements can not compensate for, no beneficial results can be obtained.' He indicated that it is important to nourish from a balanced diet, not a supplement.
