Frequently Asked Questions

We know that choosing the right supplements and vitamins is an essential part of your health and fitness journey. That’s why we’ve put together answers to the most common questions our customers ask, covering everything from ingredient transparency to usage.

Who are Nitraflex® Pre-Workout Chews for?

Nitraflex® Pre-Workout Chews are perfect for athletes and active individuals who want an explosive, performance-driven pre-workout in a fast and convenient chew. The chews are great for anyone looking to maximize strength, enhance pumps, increase endurance, and boost energy without the hassle of powders or shakers.

If I’m sensitive to caffeine and stimulants, should I use Nitraflex® Pre-Workout Chews?

If you are highly sensitive to caffeine or stimulants, Nitraflex® Pre-Workout Chews are not recommended, as a full serving delivers 200 mg of caffeine, which may be too intense for your tolerance. However, if you have mild sensitivity but still consume caffeine, Nitraflex® Pre-workout Chews offer a unique advantage—you can control your intake with precision. Each chew contains 50 mg of caffeine, allowing you to start with just 1 chew (50 mg) or 2 chews (100 mg) to assess your tolerance before increasing your dose.

How much caffeine is in Nitraflex® Pre-Workout Chews?

One serving (4 chewable tablets) provides 200mg of caffeine anhydrous.

Can I stack Nitraflex® Pre-Workout Chews with other supplements?

Yes. Nitraflex® Pre-Workout Chews can be stacked with non-stimulant supplements such as amino acids, creatine, glutamine, and protein powders. We do not recommend stacking this product with other stimulant-containing supplements.

What is the best way to take Nitraflex® Pre-Workout Chews?

As a dietary supplement, fully chew 1 serving (4 chewable tablets) with 8–10 ounces of water 30 minutes prior to training. For best results, chew thoroughly before swallowing. Maintain adequate hydration during use. DO NOT EXCEED 4 CHEWS IN ANY 24-HOUR PERIOD.

Do Nitraflex® Pre-Workout Chews contain sugar?

Yes, but less than 1g of sugar per serving, making them a low-sugar option for individuals who want performance without unnecessary calories.

Do I need to cycle Nitraflex® Pre-Workout Chews?

Yes. After 8 weeks of continuous use, it is recommended to take 1 week off before resuming use.

Are Nitraflex® Pre-Workout Chews suitable for beginners?

Key Ingredients

Key actives and what they do — open a row for the full dose detail.

L-Citrulline

To support your peak performance, L-citrulline can help increase nitric oxide production, improve blood flow, and enhance muscle pumps, allowing you to train harder and push through intense workouts.

Beta-Alanine

Beta-alanine helps buffer lactic acid buildup in your muscles during high-intensity training, delaying muscle fatigue and increasing endurance so you can maintain your performance throughout your entire workout.

Betaine Anhydrous

A proven performance ingredient that supports increased power output, strength, and muscular endurance, helping you maximize force production during brutal training sessions.

Caffeine Anhydrous

Caffeine anhydrous is a common stimulant that delivers fast-acting energy, increased alertness, and enhanced endurance, helping you stay locked in and perform at a high level from the first rep to the last.

L-Theanine

L-theanine works alongside caffeine to help promote smooth, focused energy while helping reduce annoying jitters and crashes, allowing for improved mental clarity and sustained performance until your very last rep.

Huperzine A
