For as long as I can remember I’ve been chucking back an energy drink before I hit the gym. Even when I’ve had pre-workout in the house I still often reach for a can of Red Bull to avoid feeling like my skin is crawling off my face. Thanks for that, Beta Alanine.
And while caffeine consumption offers tons of benefits, such as improved physical performance, increased alertness and focus, and enhanced mood, I also started to experience some negative side effects.
Being an evening trainer I’d often find myself unable to sleep until the early hours, and that massively impacted my energy levels the next day.
Caffeine crashes were also a common occurrence, and it felt like I was losing control of my body, which had become reliant on stimulants to function.
While looking for an alternative I stumbled across the Glutathione Rapid Boost™+ formula from RobKellerMD.

This clean energy drink mix is a caffeine-free natural supplement that boosts glutathione and nitric oxide production to increase oxygen and deliver essential nutrients to every cell in your body.

What Is Glutathione
Before we go any further, I should probably explain what glutathione actually is. Glutathione is a super antioxidant and antitoxin found in every cell of the body. Think of it as the body’s chief guardian.
It is composed of three amino acids – glutamine, cysteine, and glycine – and plays a vital role in protecting cells from damage caused by free radicals and oxidative stress.
Glutathione works by neutralising free radicals, which are highly reactive molecules that can damage cells and contribute to the development of several chronic diseases, including cancer, heart disease, and Alzheimer’s.

The body produces glutathione naturally, but various factors such as diet, stress, and environmental toxins can affect that output.
Alongside promoting glutathione production, Glutathione Rapid Boost™+ promotes the creation of Nitric Oxide, which supports blood flow and circulatory health.
So, not only does this supplement improve athletic performance, but it also prevents premature ageing and supports a healthy immune system. How? Well, let’s take a look at what’s inside.
Vitamin C
Starting off with a nice simple one, Vitamin C is important for overall health and works to protect cells from oxidants and free radical damage.
Vitamin B Complex (B3, B6, B12)
B-complex vitamins are often used to reduce fatigue, boost your mood, and support brain function.
Selenium
Selenium lowers oxidative stress which reduces inflammation and enhances immunity.
N-Aceytl Cysteine (NAC)
This is used to promote the production of glutathione, your body’s master antioxidant.
L-Citrulline
L-Citrulline is a natural nitric oxide precursor that supports improved physical and mental performance.
L-theanine
L-theanine is a compound that occurs naturally in green tea and black tea. Studies have shown it may improve mental focus and improve sleep quality.
Theobromine
This naturally occurring compound is found in dark chocolate and is known for its energising effect.
Quercetin
A natural flavonoid from plants, Quercetin acts as an antioxidant, neutralising free radicals that cause cellular and DNA damage.
Milk Thistle
Milk Thistle is a traditional healing herb and functions as an antioxidant and liver detoxification agent.
A healthy dose of all those key ingredients is packed neatly into 15 small, convenient powder sachets. Now, we’ve talked a lot about the science, so I think it’s time to bring it back around to something we can all understand – the flavor.
The sachets are fruit punch flavor – and boy do they deliver a punch. Sweetened with stevia, each one delivers a fresh, clean taste that doesn’t feel overly synthetic.

Are they as tasty as some energy drinks which are packed full of artificial sweeteners and sugar? Probably not, but they’re certainly better for you, especially at 4 calories a serving.
As for the performance, I got exactly what I was expecting. I mixed a sachet into my reusable water bottle and it dissolved without any need for protein shake-level acrobatics. Once I got it down I enjoyed a prompt, clean rush of energy without the fear of an impending sugar or caffeine crash.
My heart didn’t feel as if it was going to burst out of my chest, and when it was time to hit the hay there was no issue. Another huge thumbs up on that front.
