Personalized nutrition is advancing, with genetic insights guiding oral nutrient supplementation (ONS). Tailoring supplements to individual genotypes optimizes micronutrient status and health benefits, reducing risks and costs.
Area of Science:
- Nutritional Genomics
- Precision Medicine
- Micronutrient Metabolism
Background:
- Global challenge in achieving adequate micronutrient status.
- Widespread use of oral nutrient supplementation (ONS) to address dietary gaps.
- Emerging role of nutrigenetics in personalized nutrition strategies.
Purpose of the Study:
- To review evidence linking genetic variants to responses to common dietary supplements.
- To highlight the importance of genotype-matched ONS in precision nutrition.
- To inform healthcare professionals on optimizing supplement prescriptions.
Main Methods:
- Systematic review of published literature.
- Analysis of studies on genetic variations and micronutrient supplement responses.
- Focus on popular dietary supplements and their efficacy based on genotype.
Main Results:
- Genetic makeup influences individual responses to micronutrient supplementation.
- Specific genetic variants correlate with varying efficacy of dietary supplements.
- Evidence supports tailoring ONS based on genetic profiles for improved outcomes.
Conclusions:
- Genotype-specific supplementation enhances health benefits and micronutrient balance.
- Precision nutrition through ONS can minimize adverse events and healthcare costs.
- Integrating genetic data into ONS prescription is crucial for optimal health outcomes.
