All of us want to get an edge before we work out. It’s natural, isn’t it? To want to channel our intensity and energy into a gruelling cardio or weights session. To have the most productive workout ever without suffering a crash.

As you’ll likely already know, there are countless pre-workout supplements on the market. For this reason, we looked long and hard to find one we could believe in. One which utilised a clever blend of nature’s most nutritious foods, prepared and presented in their most organic form.

GB X-Treme by Greens Best is engineered to provide nutritional support and, thanks to the inclusion of vitamin B6, vitamin C, riboflavin and iodine, contribute to energy-yielding metabolism. The special pre-workout formula offers a synergy between nutrition, hydration and detoxification, giving you all the support you need to get the most out of your workout.

Read on to learn more about this exciting new supplement.

Why Do We Need Pre-Workouts?

The question is often asked: ‘Why do we need pre-workouts?’ It’s a valid point. Pre-workouts haven’t been around for very long, so what did we do beforehand?

Everyone’s different, of course. Some people got by with a cup of black coffee, relying on caffeine for an energy boost. Some ate a banana or apple or drank a fruit smoothie. Some worked out – and still do – on an empty stomach.

When properly formulated though, pre-workouts certainly have a place, helping us power through when otherwise we might struggle with fatigue. Good quality pre-workouts deliver better workouts and better results, nurturing the cellular foundation of the body while oxygenating cells and tissues for peak performance. And this is where GB X-Treme comes in.

Unlock Your Energy with GB X-Treme

In many ways, GB X-Treme is similar to other Greens Best formulas. Like them, it is formulated by a team of doctors passionate about quality and purity; about fusing modern science with ancient wisdom. 

In common with Rejuvenate and Cardio Renu, GB X-Treme contains concentrated fruits, vegetables and herbs (70% of them organic), as well as dairy-free probiotics to support digestion and immunity. However, a stimulating pre-workout blend has also been added. 

The pre-workout blend includes powerful amino acids like L-Lysine, L-Proline, L-Carnitine and L-Arginine, together with beneficial ingredients like Coenzyme Q10 and D-Ribose. Ancient herbal elements like fenugreek seed extract, arjuna bark powder and Chinese salvia root powder are also employed for their unique qualities. Together, these carefully selected components provide exceptional nutritional support.

More Than Just a Pre-Workout 

Although mainly known for its energy-boosting properties, it would be inaccurate to say that GB X-Treme is solely a pre-workout. There are quite a few stimulating pre-workout supplements available, but GB X-Treme is so packed with nutrition that it could more accurately be labelled an ‘all-in-one’.

The formula contains alkaline super greens (spirulina, chlorella, kale leaf), antioxidant-rich fruits (goji berry, pomegranate, hawthorn berry), dietary fibreomega-3s from flaxseeds, eight separate probiotic strains and coconut fruit powder

As if that wasn’t enough, the Greens Best pre-workout contains vitamins A, B6, C and E, and important minerals like calcium, iron, iodine and sodium. Oh, and eight grams of vegan-friendly protein per serving into the bargain.

Use a Supplement You Can Trust

Many pre-workout supplements promise the world and deliver little to no value. In fact, some induce headaches, provoke jitters and cramps and play havoc with your sleeping patterns.

That’s why it’s important to use a pre-workout you can rely on. One that contains all natural ingredients, is safe to use and yet still provides the boost you need to maximise your workout. 

GB X-Treme is just that: an intelligent formulation based on the principles of modern science, natural medicine, Ayurveda and Oriental medicine. Formulated by experienced doctors, it is healthy, nutritious and tastes fantastic. Make it part of your pre-workout routine and achieve your fitness potential.
