Summary
Adolescents frequently use dietary supplements for body image and performance, but evidence of benefits is limited. Unrestrained use is discouraged due to adverse effects; balanced nutrition is typically sufficient for athletic goals.
Area of Science:
- Sports Medicine
- Adolescent Health
- Nutritional Science
Background:
- Dietary supplement consumption is prevalent among adolescents.
- Motivations include achieving an ideal body, compensating for poor diet, and enhancing athletic performance.
- This practice is frequently observed in clinical settings.
Purpose of the Study:
- To review the usage patterns, benefits, and adverse effects of common dietary supplements in adolescents.
- To evaluate the scientific evidence supporting supplement use in this demographic.
Main Methods:
- A literature review was conducted using MEDLINE and LILACS databases.
- The search spanned from 1997 to 2008, analyzing 377 articles and selecting 52 references.
Main Results:
- Commonly used supplements like proteins, amino acids, and vitamins show limited evidence of benefit for healthy adolescents.
- Supplements are often used without proven efficacy for improving athletic performance or health.
- Potential benefits may exist for competitive athletes with diagnosed deficiencies.
Conclusions:
- Avoidance of unrestrained dietary supplement consumption in adolescents is recommended.
- Balanced nutrition is generally sufficient for optimal athletic performance.
- Supplement use should be restricted to cases with identified nutritional deficiencies.

01:30Vitamins
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced in our...
01:02Prescription, Nonprescription and Orphan Drugs
Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...

01:29Drug Dosing: Infants and Children
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
01:25Dosage Regimen: Multiple Oral Dosage
Understanding how a drug's concentration fluctuates within the body over time is crucial in pharmacokinetics, particularly with multiple oral doses. A graphical representation of multiple oral dosages provides insight into these dynamics. Typical accumulation curves of a drug's concentration in the body reveal a sawtooth pattern, indicating periodic peaks and troughs correlating with each dose administration and the drug's subsequent elimination.The plasma concentration at any time during an...
01:28Dosage Regimens: Designs and Approaches
Designing a dosage regimen, which refers to the manner of drug administration, is a complex process involving the selection of drug dose, route, and frequency. This process is underpinned by pharmacokinetic parameters derived from tests and population averages. These parameters are then tailored to patient-specific variables such as diagnosis, demographics, and allergy status. Once therapy commences, therapeutic response monitoring is critical and achieved through clinical and physical...
01:23Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption
Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
