From busy school schedules and sports to long study sessions and digital fatigue, teenagers are turning to functional drinks to power through their day. These beverages—once popular among fitness buffs and wellness enthusiasts—are now marketed to younger audiences promising energy, focus, hydration, and even stress relief.
But how safe are functional drinks for teens? Are they genuinely beneficial, or is this a wellness trend best approached with caution?
What Are Functional Drinks?

- Energy drinks (natural or synthetic caffeine)
- Nootropic drinks (brain-enhancing)
- Vitamin-infused waters
- Hydration boosters (electrolyte-rich)
- Adaptogen blends (herbs like ashwagandha, ginseng)
Types Popular with Teens
- Focus beverages marketed for studying or gaming
- Pre-sport hydration drinks with vitamins and electrolytes
- Mood boosters with calming agents
Key Ingredients in Functional Drinks for Teens
Caffeine Levels and Age Guidelines
According to health organizations like the American Academy of Pediatrics, teens aged 12–18 should limit caffeine to 100 mg/day. Many functional drinks fall within or exceed this amount.
- Safe: Green tea extract (20–40 mg), matcha (30–70 mg)
- Risky: Guarana or synthetic caffeine (up to 200 mg per can)
Sugar Content and Artificial Additives
- Teens already consume high sugar levels via diet.
- Drinks exceeding 10g of sugar per serving can lead to insulin spikes, mood swings, and long-term metabolic issues.
- Artificial colors and preservatives may trigger hyperactivity or allergies in sensitive individuals.
