How to Use Food Supplements Properly?
Use of Supplements
Although a balanced diet is necessary for good health, our current living patterns sometimes tend to interfere with this balance. In this case, it may be advisable to opt for food supplements in order to compensate for possible intake deficiencies.
Recommended Nutritional Intake
Official nutritional intakes are referred to under different names depending on the country and their standards may vary. They indicate, by age and sex, how much nutrients are needed to maintain good health. By assessing your daily intake of each essential nutrient, you will be able to suspect a possible deficiency. However, it is strongly recommended to check with your doctor or pharmacist before taking a food supplement. Remember to read the leaflet carefully, especially if you decide to combine different types of food supplements.
Some special situations may require the use of food supplements to compensate for the lack of certain nutrients. Some doctors strongly recommend that pregnant patients take supplements containing iron, calcium or vitamin B9 as these nutrients are essential for a healthy pregnancy. Women with heavy periods may also need to take an iron supplement. People with special diets, such as vegetarians and vegans, or very active people are also more likely to need to use food supplements.
Read the Label of Food supplements carefully
The label of a food supplement must include the following information:
- The names of the categories of nutrients or substances characterizing the product or an indication of the nature of these nutrients or substances
- The number of vitamins and minerals present in the product must be indicated in numerical form in weight units
- The percentage of vitamins and minerals in relation to the recommended daily intake must be indicated
- The recommended daily consumption must be recorded
- The label must indicate how the product is to be used (quantity, frequency, special circumstances)
- A warning that it is not recommended to exceed the indicated daily dose
- A statement that food supplements should not be used as a substitute for a healthy and diversified diet
- A warning that products should be kept out of the reach of children
Food supplements should not replace the intakes that need to be supplemented by food but should complement them. In addition, it is advisable to follow the dosage carefully as a sub-dose will have no effect and an overdose may cause adverse reactions.
Deficiencies in France
By following dietary recommendations that help you know how to eat a balanced diet, a person should consume all the vitamins and minerals they need on a daily basis. However, a study conducted by the Institut de Veille Sanitaire (InVS) revealed that nearly 80% of the French population suffers from vitamin D deficiency.
Another important deficiency is iron deficiency: between 20% and 25% of the world’s population would be affected, this is called iron deficiency anemia. These deficiencies are partly linked to a diet that is not very varied and low in fruit and vegetables.
Ineffectiveness of Certain Supplements
A study carried out in 2006 and 2007 by the Agence Française de Sécurité Sanitaire des Aliments (AFSSA) showed that 20% of adults had consumed at least one food supplement during the year. However, there is not enough research or scientific rigor to demonstrate with certainty the effectiveness of food supplements. In 2010, for example, a study presented at the International Congress on Obesity in Stockholm, Sweden, highlighted the ineffectiveness of supplements for slimming.
Risks with Excessive Intake
The majority of food supplements are highly concentrated in vitamins and minerals. Unsafe consumption can, therefore, be dangerous to health. Various studies have identified risks of cardiovascular disorders, increased mortality in older people, the development of certain types of cancers, including lung cancer, bone problems, and kidney dysfunction. Be careful when taking a food supplement. The advice of a health professional is strongly recommended.
Interactions with Other Nutrients
Many dietary supplements may interact with each other and/or with certain drug treatments. Possible interactions should be taken very seriously to avoid serious consequences. In general, do not practice self-medication and talk to your doctor about your supplementation project.
