Energy drinks have become a staple for those looking for an extra boost throughout the day, whether you’re powering through work, exercise, or a late-night study session. Among the most popular brands is NOS Energy Drink, known for its bold flavor and high-energy formula.
But if you’re a health-conscious consumer or curious coffee drinker wondering: “Does NOS Energy Drink have caffeine?”—you’re not alone.
NOS Energy Drink does contain a significant amount of caffeine – 160mg per 16 fl oz can. This puts it on par with other leading energy drinks and roughly equivalent to two cups of coffee.
Understanding its complete ingredient profile, nutritional impact, and potential side effects is crucial before deciding to make it part of your daily routine.
Whether you’re a coffee aficionado comparing caffeine sources, a health-conscious consumer evaluating your beverage choices, or someone experiencing concerning side effects.
This comprehensive guide will provide you with the evidence-based information you need to make informed decisions about NOS Energy Drink consumption.
Does NOS Energy Drink Contain Caffeine?
Yes, NOS Energy Drink contains caffeine as one of its key active ingredients that provides stimulating effects. Understanding the precise caffeine concentration helps you manage your daily intake and compare different beverages effectively.
NOS Energy Drink Caffeine Content Per 100ml
Per 100ml: 33.81mg caffeine Per 16 fl oz can (473ml): 160mg caffeine Per 8 fl oz serving: 80mg caffeine
This means that a standard 473ml can of NOS delivers 160 milligrams of caffeine, placing it in the moderate-to-high range of caffeinated beverages.
How NOS Compares to Other Beverages
To put NOS in perspective for coffee enthusiasts and caffeine consumers:
- NOS Energy Drink: 33.81mg per 100ml
- Red Bull: 32mg per 100ml
- Monster Energy: 33mg per 100ml
- Bang Energy: 113mg per 100ml
- Brewed Coffee: 40-95mg per 100ml
- Espresso: 212mg per 100ml (consumed in smaller quantities)
NOS contains similar caffeine levels to other mainstream energy drinks like Red Bull and Monster, making it a comparable choice in terms of stimulant content.
Caffeine Absorption and Effects
The caffeine in NOS is synthetic caffeine, which is absorbed more rapidly than naturally occurring caffeine found in coffee. This means you may feel the effects within 15-30 minutes, but the duration might be shorter compared to coffee consumption.
The general guideline is that 400 milligrams of caffeine per day is safe for most healthy adults, so a single can of NOS represents 40% of this recommended daily limit.

Frequently Asked Questions (FAQs)
1. How much NOS Energy Drink is safe to consume per day?
Most health experts recommend limiting energy drink consumption to one can per day maximum. Since NOS contains 160mg of caffeine per can and the FDA recommends no more than 400mg of caffeine daily for healthy adults, you could theoretically consume 2.5 cans. However, considering the high sugar content (54g per can) and other stimulants, one can per day is the safer limit. Pregnant women, teens, and those with heart conditions should avoid energy drinks entirely.
2. When is the best time to drink NOS Energy Drink?
The optimal time to consume NOS Energy Drink is during the morning or early afternoon, ideally before 2 PM. This timing allows the caffeine to provide energy when you need it most while ensuring it doesn’t interfere with your sleep cycle. Avoid drinking NOS within 6-8 hours of bedtime, as the 160mg of caffeine can significantly disrupt sleep quality and duration.
3. Can I mix NOS Energy Drink with alcohol?
No, mixing NOS Energy Drink with alcohol is extremely dangerous and strongly discouraged. The combination can mask alcohol’s depressant effects, leading to overconsumption and increased risk of alcohol poisoning. The stimulants in NOS can also put additional stress on your cardiovascular system when combined with alcohol, potentially causing dangerous heart rhythm irregularities.
4. Is NOS Energy Drink worse than coffee?
From a caffeine standpoint, NOS (160mg per can) and coffee (95-200mg per cup) are comparable. However, NOS contains 54g of added sugar, artificial ingredients, and preservatives that coffee lacks. Coffee provides antioxidants and has been linked to various health benefits, while energy drinks like NOS primarily offer stimulation with potential negative effects from high sugar content. For health-conscious consumers, black coffee or coffee with minimal natural sweeteners is generally the better choice.
5. What should I do if I experience side effects from NOS Energy Drink?
If you experience mild side effects like jitters, headache, or stomach upset, stop consuming NOS immediately and drink plenty of water. These symptoms typically resolve within 4-6 hours as caffeine levels decrease. For severe symptoms like chest pain, irregular heartbeat, severe anxiety, or difficulty breathing, seek medical attention immediately. To prevent future issues, consider reducing your caffeine intake, choosing smaller serving sizes, or switching to lower-caffeine alternatives like green tea.
