Performance Lab Stim Review

Our bodies naturally produce energy by metabolizing and converting the food we eat into adenosine triphosphate (ATP) via the mitochondria located in each one of our cells. That’s why it’s so important to ensure you eat a healthy, balanced, and regular diet throughout the day. 

Despite our body’s natural ability to produce energy, many of us experience periods of tiredness and exhaustion at certain points of the day — even if we’re eating the right diet. This can be quite frustrating for anyone, especially if you have plans or a to-do list that needs to get done. 

That’s why so many people turn to energy drinks, such as Monster, Red Bull, Rockstar, and Bang. These energy drinks contain a lot of caffeine and other chemicals, which certainly give you that boost of energy you’ve been searching for, but they’re also extremely unhealthy. 

Instead of turning to those harmful energy drinks, most people would benefit from a healthy energy-boosting supplement — such as Performance Lab Stim. The question is, though, is this the right energy booster for your needs? Don’t worry; we’re going to detail everything you need to know about this particular supplement and if you should consider it in this complete review of Performance Lab Stim. 

What Is Performance Lab Stim?

Performance Lab Stim is one of the most popular energy-boosting supplements on the market today. It’s produced and manufactured by Performance Lab Ltd., a secondary company of Opti-Nutra Ltd. — one of the most trustworthy and effective supplement brands available today.

Performance Lab Ltd. is home to a wide range of different supplements designed for both sport and healthy living. They have two product categories — SPORT Range and CORE Range — with Performance Lab Stim falling under their CORE Range line. Here’s a look at what they offer:

  • SPORT Range – includes Protein, Carb, BCAA, Pre, Post, Main, and SPORTMixer. 
  • CORE Range – includes Energy, Stim, MCT, Multi Men’s, Multi Women’s, Omega 3, PL-Immune, Mind, Sleep, Prebiotic, and Flex.

Performance Lab Stim’s formula is a rather basic formula that contains just three ingredients, as well as four vitamins, but don’t let that fool you. It focuses on giving your body what it needs for a fast-acting energy boost, while avoiding all those harmful chemicals that your body simply doesn’t need. 

Stim by Performance Lab

Unlike their Performance Lab Energy formula, their Stim formula contains natural caffeine. The good news is it’s such a small amount of caffeine that it won’t harm you. It also contains two other ingredients that help alleviate some of the unwanted and annoying side effects of caffeine. 

Before we dive deeper into what those ingredients are and how they work in conjunction with one another, we’re going to explain a little bit more about what this supplement is, why you can trust it, how to avoid those caffeine side effects, and how to avoid consuming too much caffeine. 

What do stimulants do to the body?

Stimulants are a class of drugs that can have beneficial effects on the body, but only when used in the right circumstance. They work by stimulating the nervous system, including the brain and spinal cord, by increasing the brain’s production of catecholamines (neurotransmitters).

These neurotransmitters include dopamine, epinephrine (adrenaline), and norepinephrine (noradrenaline). They are responsible for signalling reward and motivation in the brain, which can increase an individual’s energy and level of alertness — among other things in the body. 

The most popular stimulant that’s consumed by nearly everyone is caffeine, though there are others that fall under this category — including nicotine, cocaine, Methamphetamine, MDMA, amphetamines, methylphenidate, and other prescription stimulants more harmful than caffeine. 

How much caffeine is too much?

Caffeine is found in a variety of beverages that most of us consume daily. For example, it can be found in coffee, tea, soda, energy drinks, espresso, iced tea, hot chocolate, and even dark chocolate. It’s no surprise that most of us often rely on caffeine to help us get through the day. 

Although it’s a big part of most people’s daily diet (and comes with some major benefits), caffeine can be extremely dangerous when too much is consumed. To be safe, the FDA recommends never consuming more than 400mg of any type of caffeine per day. 

For reference, that’s equal to around four cups of coffee, two energy drinks, or 10 cans of soda. For those that rely on two cups of coffee, an energy drink, and a can of soda each day, you’re already over the limit and should definitely cut back — as well as avoid adding a supplement. 

Is it possible to avoid crashes and jitters with caffeine?

When we consume caffeine, whether it be in the form of coffee, espresso, soda, or an energy drink, there’s no doubt it speeds up our central nervous system and makes us feel awake. With that said, it doesn’t come free and often results in a wide range of side effects in the body.

Two of the most common side effects of caffeine include jitters and an eventual crash. Both of these can make consuming caffeine a wild ride that can easily put a damper on your day, especially if that crash comes earlier than expected and you still have work to do for the day.

The good news is there are ways to reduce these side effects. One of the best ways is with an amino acid called L-Theanine, which is naturally found in tea. It reduces stress, increases Alpha brain waves, promotes dopamine and serotonin production, and regulates blood pressure levels. 

L-Tyrosine is another amino acid that can help reduce the side effects. It helps the brain perform when under stress or in high-pressured situations, as well as supporting the production of catecholamines in the brain. Together, L-Theanine and L-Tyrosine are necessary with caffeine. If caffeine is a larger issue for you and you want to cut it out completely, Performance Lab Energy is caffeine-free as well as other energy supplements such as Energy Renew

Can you trust Performance Lab with your supplement?

We’re going to dive into the ingredients found in the Performance Lab Stim formula below, but you’re likely wondering what makes Performance Lab such a reputable and trustworthy supplement brand. After all, there are so many other companies that come with similar claims. 

Performance Lab is intent on ensuring a quality product by not only using the right ingredients, but using the right nutrient form of each ingredient and the right dosage. This ensures your body is familiar with the nutrients it’s getting and that your body gets those nutrients at the right time. 

They operate out of a facility that’s FDA-registered, NSF cGMP compliant, NPA-certified, UL-certified, 21 CFR Part 111 compliant, Prop 65 compliant, USDA Organic certified, meet USP standards, HACCP-certified, STR-certified, ESC compliant, and US Pharmacopeia certified. 

As a cherry on top, their Stim formula is prebiotic-infused, utilizes lab-grown vitamins, is GMP-certified, vegan-friendly, non-GMO, non-irradiated, and free of synthetic additives, soy, gluten, allergens, and banned substances. It’s an all-around good product, which is rare today.

Performance Lab Stim Ingredients

Now that we fully understand the background behind the Performance Lab company and Stim formula, we can start to embrace what makes this formula so popular and effective. That’s right; we’re finally going to take a good, hard look at the ingredients that make up the Stim formula. 

There are seven total ingredients — Vitamin B2, Vitamin B6, Vitamin B9, Vitamin B12, Natural Caffeine, L-Theanine, and L-Tyrosine. Together, these ingredients help support a boost of energy and mental alertness, while also helping relieve those nasty side effects and calm the nerves. 

Performance Lab Stim -Supplement Facts

Let’s take a closer look!

Vitamins

Vitamins are organic compounds that the body needs in small, trace amounts — either because the body doesn’t produce them on its own or because the body doesn’t produce enough of them. The Stim formula contains four of them, all of which are in the B-Complex Vitamins group. 

Let’s see what makes them so special:

  • Vitamin B2 – also known as Riboflavin, a water-soluble vitamin, known for red blood cell formation, energy production, antioxidant properties, and cell growth. 
  • Vitamin B6 – also known as Pyridoxine, a water-soluble vitamin, known for synthesizing and converting brain chemicals, immunity, blood cell formation, transporting oxygen, cognitive function, energy production, nervous system, and blood sugar levels. 
  • Vitamin B9 – also known as Folate (natural) or Folic Acid (synthetic), a water-soluble vitamin, known for DNA synthesis, forming new cells, and energy production. 
  • Vitamin B12 – also known as Cobalamin, water-soluble vitamin, known for energy metabolism, heart health, nervous system health, and cognitive function. 

To make these vitamins even more effective, Performance Lab curates them in a lab through a process they call NutriGenesis®. They do this by seeding live single-cell organisms with the micronutrients in a hydroponic medium. They’re equivalent to what you get through whole foods.
