What exactly are customized vitamins?

Some companies claim to sell customized vitamins that they will tailor according to an individual’s particular health conditions, genetic makeup, or both.

They differ from traditional dietary supplements, which provide equivalent types and amounts of vitamins to anyone who takes them.

Numerous companies offer custom vitamins within us, including:

Most of those who sell custom vitamins claim to base their customization on a web questionnaire that customers can complete in a couple of minutes. These surveys collect information on:

  • physical activity level
  • medicines
  • health concerns
  • intakes of certain staple foods, such as vegetables or food sources of calcium

Companies may also claim that they base their vitamin customization on a person’s DNA test results. This proof comes from nutrigenomicsTrusted Source, a scientific field that explores how a person’s nutrient intake, genetic makeup, and health interact. These companies claim that they use the test results to predict the danger of developing various diseases and, at the same time, recommend the intake of certain vitamins.

Can they have any welfare benefits?

Studies on personalized vitamins are limited. there is little research to support its benefits, especially compared to non-personalized options.

The US government exercises limited oversight over companies that sell personalized vitamins. An earlier study by the Government Accountability Office (GAO) found that these vitamins may not only not improve health, but the companies that sell them may provide misleading or unreliable health information.

One of the most convincing arguments provided by these providers is that they adapt nutrients to a person’s particular health specifications. The GAO study looked at the authenticity of this assertion by researching four companies that run this service using false profiles. After completing the online surveys, the authors submitted DNA samples for processing.

In handing over the test results to the study authors, the websites urged purchasing expensive custom vitamins. However, the recommended vitamins for each of the fictitious profiles were equivalent rather than customized. This is of particular concern because the profiles come from the DNA samples of two people with different lifestyles.

Furthermore, according to the American Society for Nutrition (ASN), there is inadequate data to prove that consuming multivitamins reduces chronic or long-term illness in general. Despite limited evidence showing that they may aid in some situations, this is often the case.

Risks and factors to remember

Online surveys and questionnaires offered by most personalized vitamin brands may not be accurate or may not be interpreted correctly.

A person’s medical history and family history contribute to their nutritional needs. This makes analysis of online surveys and results complex and unlikely to be definitive or complete. For these reasons, a person’s physician is often the most appropriate professional to interpret these tests.

The ASN cautions that taking vitamins can increase the likelihood of receiving the tolerable maximum intake (TUI) for some nutrients. this will cause health risks.

For example, when people take a supplement that contains vitamin Bc, they will exceed the TUI if they eat foods fortified with the vitamin. High levels of vitamin Bc can increase the danger from reliable sources of certain types of cancer, such as adenocarcinoma of the prostate.

Issues arising from erroneous analysis of DNA tests

When custom vitamin brands offer DNA testing, they are generally trying to find the likelihood of gluten intolerance, caffeine metabolism, the antioxidant capacity of the skin, and more. They will even be evaluating the danger of certain conditions.

According to the Federal Trade Commission (FTC), no research indicates that DNA testing provides a safe basis for personalizing dietary supplements.

The FTC states that it is often difficult to draw definitive conclusions about the health risks supported by DNA testing. This is often because the likelihood that a person will develop a particular condition often does not depend solely on their genes. Rather, it depends on multiple interactions between your genes and therefore the foods you eat, your lifestyle. The substances that you need frequent exposure to, such as tobacco or sunlight.

The Food and Drug Administration (FDA) trusted source warns that two problems can arise if DNA tests are misinterpreted. the primary may be a positive result for a particular disease. Which does not necessarily mean that a person will develop the condition or that it will be serious.

The second problem involves a negative result for a particular disease. This could simply indicate that the test did not look at the actual genetic changes related to the condition. Most DNA tests only check a small number of genes.

As the GAO study concludes, a positive result can unduly alarm people. It encourage them to require expensive personalized vitamins to stay healthy. Also, a negative result can give some people false assurance that they are healthy once they are literally sick.

Supplements that are not tailored

Instead of taking personalized vitamins, FDATrusted Source advises annual checkups. Evaluations for people looking to diagnose potential illnesses and take preventative measures.

The FTC suggests that an honest starting line can be a medical exam that has conventional laboratory tests. Such as blood chemistry and a cholesterol profile. If tests show abnormalities, a doctor can make dietary and other lifestyle recommendations.

A certified dietitian may assist anyone who wants to maintain a diet that ensures adequate nutrition. This health provider will build a comprehensive meal schedule that takes into account a person’s diagnosed health problems as well as their food habits.

If people believe they are deficient in certain nutrients, they should undergo blood test evaluations by a doctor. Health professionals believe that these tests evaluate certain deficiencies, for example, vitamin B12 and vitamin D deficiencies.

Working with qualified healthcare professionals, such as dietitians It can help determine if an individual’s diet is lacking in certain nutrients and if supplementation is acceptable.


Companies that sell personalized vitamins may claim to supply vitamins tailored to suit a person’s health needs. However, they are not always delivering on the current promise. These supplements can also include dangerous amounts of certain vitamins that will negatively affect health.

A better alternative than investing in personalized vitamins is to request a medical exam and work with healthcare professionals to receive dietary and lifestyle recommendations.
