☕ Caffeine in NOS Energy Drink

👉 A 16 fl oz (473 ml) can of NOS Original contains 160 mg of caffeine—roughly 10 mg per ounce 

👉 The larger 24 oz can contains approximately 240 mg of caffeine.

👉 That’s equivalent to:

- A 16 oz Monster (160 mg)

- Two 8 oz Red Bulls (80 mg each)

- About 1.5 cups of brewed coffee

 

Why It Matters

Health experts agree that up to 400 mg of caffeine per day is safe for most healthy adults. However, consuming a 24 oz can of NOS (240 mg) covers more than half of that limit in one serving.

⚠️ Health Considerations

1. Cardiovascular Effects

NOS’s high caffeine content can increase heart rate and blood pressure.
Energy drinks have been linked to palpitations and rare cases of arrhythmia, especially when consumed in excess.

2. Digestive Issues

Caffeine and L‑carnitine in NOS may cause diarrhea or stomach upset.

3. Dehydration & Caffeine Crash

Caffeine’s diuretic effect can contribute to dehydration. Following the buzz, you may experience fatigue, irritability, or headaches .

 

✅ Practical Tips

👉  Limit yourself to one 16 oz can daily unless you’re monitoring total caffeine from other sources.

👉  Avoid drinking NOS too close to bedtime to prevent sleep disturbance.

👉  Stay hydrated and keep an eye on impacts to your heart or digestion.

👉  Individuals who are pregnant, have heart conditions, or are caffeine-sensitive should reduce intake or avoid energy drinks.
