As with most things in life, consistently performing at 100% is extremely hard to achieve. Many of us fitness enthusiasts can probably relate to this frustration.

Sometimes we have more energy or have the mental capacity to push ourselves harder. Other times we feel lethargic and leave a workout feeling disappointed with our performance. That’s where pre-workouts come in.

Taking a pre-workout supplement can boost your athletic performance, accelerate your fitness goals, and aid your recovery. However, taking a pre-workout that contains high doses of caffeine can negatively affect the heart in several ways.

If you’re looking to maximize your workout with a performance-enhancing supplement, it’s important to use them with caution. Choosing a supplement that is low in caffeine can offer all the same benefits, without harming your heart.

Keep reading to find out how a low-caffeine pre-workout supplement can give you that little extra boost to increase your performance.

What is a Pre-Workout?

A pre-workout is a supplement you can take before you exercise which boosts your energy and optimizes your performance1. They usually contain a combination of different ingredients that enhance energy and strength, such as vitamins, amino acids, and caffeine.

The caffeine in a pre-workout can increase your energy levels and delay fatigue, allowing you to push yourself that little bit further. It also stimulates the release of the happiness hormone dopamine, which can help put us in the right positive mindset to really go for it!

According to the US Food and Drug Administration, it is safe to consume up to 400mg of caffeine a day. In other words, roughly 4 cups of coffee a day, depending on how strong you like it, of course. Regularly exceeding this recommended amount may pose a number of risks to heart health.

Is Pre-Workout Safe?

The reason why taking a pre-workout supplement is sometimes considered bad for your health is because they often contain high doses of caffeine - much higher than the recommended amount.

In some pre-workouts, just one serving provides the maximum dose of caffeine. Excessive caffeine consumption is known to have negative effects on your heart, including increasing blood pressure, heart palpitations, and risk of heart attack2.

While some pre-workout supplements can negatively impact your heart health, those with low doses of caffeine do not pose the same risks. For example, Pre Lab Pro workout support is safer to use than many other pre-workouts, thanks to its ability to deliver smarter stimulation that energizes your workout with less caffeine.

This advanced formula contains some of the most powerful pre-workout ingredients to promote a wide range of strength, cardiovascular endurance, recovery, and overall health benefits that advance you towards your fitness goals.

Benefits of Taking a Pre-Workout

Taking a pre-workout low in caffeine enables you to maximize your workout performance and take advantage of all the other benefits of a pre-workout, whilst ensuring your heart remains healthy. Here’s how:

Increases blood flow

During a workout, your heart works in overdrive to pump the necessary oxygen and nutrients to your muscles to fuel their movement. Pre-workouts often contain compounds that your body uses to make nitric oxide, a vasodilator that causes blood vessels to widen, thus increasing blood flow.

Research suggests supplements containing these compounds can enhance athletic performance3. This is because increased blood flow helps deliver more oxygen and nutrients to your muscles.

These include essential proteins and antioxidants to support the building and repairing of muscle tissue. Blood leaving your muscles also helps remove painful lactic acid. Thus enabling you to fight fatigue and increase strength, power, and performance.

But not only is blood flow important for your muscles, but it also powers your brain! Increased circulation sustains mental energy, focus, and drive, allowing you to work out harder for longer.

Pre Lab Pro uses beetroot powder, a rich source of nitrates that elevates levels of nitric oxide in the blood. It also contains antioxidants to help protect muscles from damage and to optimize recovery.

By cleverly blending red beetroot powder with L-Glutathione and L-Citrulline, this pre-workout maximizes circulation with a longer-lasting effect.

Boost energy

When used correctly, caffeine can be a powerful tool to unleash greater athletic performance. It works by dilating blood vessels to increase blood flow and improves brain power for better focus.

This helps increase muscle performance and endurance and means you can accomplish more without feeling like you are pushing yourself harder. No one wants to feel like they are slogging away but not seeing the desired results.

Pre Lab Pro contains smarter ingredients to energize your workouts, whilst minimizing the harmful effects of caffeine. Containing natural caffeine at a moderate 80mg dosage - well under the recommended limit - this pre-workout can enhance performance without posing harm to your heart.

A number of complementary ingredients are also included to minimize side effects and enhance desired effects - no more jitters or energy crashes. These include:

  • L-tyrosine: for better brain function and focus
  • L-theanine: to enhance caffeine benefits and reduce side-effects
  • Himalayan salt: to maintain hydration against caffeine and exercise-induced fluid loss
  • B vitamins: to restore those depleted by caffeine and exercise, which are needed for intense exercise

Enhanced recovery

Exercise puts the body under a lot of stress and depletes it of important substances such as brain chemicals, oxygen, nutrients, and electrolytes. The harder you train, the greater the demand on your body. It's always important to restore your body to its original state post-workout.

When your body becomes depleted, you experience fatigue, your performance will suffer, and your ability to perform everyday activities may be affected. Without proper recovery, you also won’t be able to reap the benefits of your hard work.

Pre-workout supplements such as Pre Lab Pro provide ingredients to support those that are depleted during exercise, helping you maintain intensity during your workouts and allowing you to bounce back faster.


Taking a pre-workout that is low in caffeine can provide numerous benefits for your athletic performance, without posing risks to your heart health.

A supplement that contains ingredients to improve blood flow, boost energy, and speed up recovery can help you take your workouts to the next level. Try Pre Lab Pro to help you reach your fitness goals faster!
