Summary
Many dietary supplements contain undeclared substances, posing a risk of unintentional doping for athletes. Over 28% of products analyzed contained banned compounds, highlighting the need for caution with supplements.
Area of Science:
- Sports Science
- Analytical Chemistry
- Pharmacology
Background:
- Athletes use dietary supplements (DS) for recovery and performance.
- Non-prohibited DS can pose risks, including unintentional doping from contaminated products.
- Undeclared compounds in DS are a significant concern in professional sports.
Purpose of the Study:
- To evaluate the risk of unintentional doping in athletes due to contaminated dietary supplements.
- To identify the prevalence of undeclared substances in DS.
Main Methods:
- A comprehensive literature search was conducted across major scientific databases (PubMed, Science Direct, Google Scholar, Web of Science).
- Studies analyzing DS for banned substances, as defined by the World Anti-Doping Agency (WADA), were included.
- The review synthesized data from 50 studies published up to June 2021.
Main Results:
- A total of 3132 DS were analyzed.
- 875 (approximately 28%) of the analyzed DS contained undeclared substances.
- Sibutramine and anabolic-androgenic steroids were the most frequently detected undeclared compounds.
Conclusions:
- Over 28% of analyzed dietary supplements present a risk of unintentional doping.
- Athletes and support teams must exercise extreme caution when selecting and using DS.
- Awareness of DS contamination risks is crucial for maintaining anti-doping integrity.

01:25Drug Regulation
1.9K
Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...

01:30Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
217
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

01:28Proteins: Dietary Sources and Requirements
675
Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...

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...

Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.

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...
