Ingredients like Green Tea, Green Coffee Bean and Caffeine have become popular in many proprietary, fat burners, energy drinks and pre-workouts. However, what the consumer often misinterprets is the therapeutic amount needed to give a possible positive effect.

Extreme Green Pre-Workout has been formulated on the basis of 3 main compounds EpigallocatechinGallate (EGCG), Chlorogenic Acid (CGA)and Caffeine. After analysing years of studies we have come to the conclusion that these are the active compounds responsible for the weight loss and exercise performance effects seen by consuming Green Tea, Green Coffee Bean and Caffeine.

At Bonsai Biotics we have looked at numerous clinical studies to ensure you get the right strength and amount of each of these key ingredients, however not only that we have ensured you get them in their natural forms meaning you get a supplement without synthetic analogues which is more tolerable for the body.

What is a dietary supplement?

Dietary supplements include vitamins, minerals, herbs, botanicals, enzymes, amino acids, or other dietary ingredients. You take these products by mouth in pill, capsule, tablet, or liquid form to supplement your diet.

Are all supplements tested to make sure they're safe and effective?

No. Manufacturers aren't required to test their products for safety and effectiveness. Some supplement ingredients have been tested in animal or human studies. However, all Bonsai Biotics supplements have been formulated by clinical pharmacists using evidence based research to ensure you receive a safe and effective supplement.

How can I tell whether I'm getting a good quality supplement?

Manufacturers are required to follow "good manufacturing practices" (GMPs), which means their supplements have to meet certain quality standards. However, it has been found that some products may contain more or less of the ingredient than is stated on the label. Or, in some cases they may contain ingredients not listed on the label. At Bonsai Biotics we pride ourselves on making pharmaceutical grade supplements meeting the highest manufacturing standards available, with our manufacturing facility receiving a Triple A standard in manufacturing.

How do I know whether a supplement's claims are true or false?

Supplement makers are not allowed to claim their product diagnoses, treats, cures, reduces the symptoms of, or prevents disease. We at Bonsai Biotics agree with the above and believe in the ethos "Shin-Zen-Bi", which stands for Truth, Goodness and Beauty. Therefore we can assure you that any claims we make are backed up with scientific evidence.

What is a 'proprietary blend?'

A "proprietary blend" is a combination of ingredients used exclusively by one supplement manufacturer. No other company produces the exact same combination of ingredients, and, in most cases, it is difficult to know from the label the exact amounts of each of the ingredients in that blend. At Bonsai Biotics we refuse to hide behind a proprietary blend as we want the consumer to have all information regarding the supplements. We will only use therapeutic doses that have clinically been shown to exert a positive effect. Also unlike other supplement companies, we won't cram in loads of ingredients that look good at sub therapeutic levels. Remember more is not always better.

What is the difference between RDA and DV?

Recommended Dietary Allowance (RDA) is the amount of a certain nutrient you should get each day based on your age, gender, and whether you are pregnant or breastfeeding. On a supplement label, you're more likely to see the acronym DV, which stands for Daily Value. This represents how much of a nutrient the supplement provides in regards to a total daily diet.

How is the best way to take Extreme Green Pre-workout?

Extreme Green Pre-workout is best taken at least 30 minutes prior to undertaking exercise. Depending on your caffeine tolerance the recommended dose varies between 1-3 capsules before a workout. At Bonsai Biotics we recommend a 7 day break period after taking the supplements for ONE month, so the body doesn’t become tolerant to the positive effects. Once the 7 day break period has elapsed, continue to take as normal for another month.

Unless you are allergic to coffee or caffeine, it is a very safe ingredient. However most green coffee supplements contain some caffeine.

“I’m not a big fan of pre-workouts – from experience I’ve generally felt a tingling sensation in my lips and the sudden ‘kick-in’ once it’s in my system. However, having recently tried the pre-workout from Bonsai Biotics I’ve been pleasantly surprised. This comes in a capsule form rather than as a powder/shot and it doesn’t have an unpleasant taste. Actually, it doesn’t have any taste at all!

After using the product for only a few days I started to feel I had more energy and stamina during my cardio workouts and could squeeze in more minutes to the duration of HIIT circuits. My compound lifts have improved and I’ve added extra reps and weight to my strength training.”

Jit Tamber – Competitive Bodybuilder, Derby

“I have never really tried a pre-workout, so was a bit hesitant to use Extreme Green Pre-workout. I normally have a black coffee before I train and that does he job. I actually felt more energised and pumped after taking the pre-workout, felt unreal. My friend and I trained harder than before and we felt like we could keep going for longer.

This is definitely a supplement I will recommend to my clients. Unlike drinking coffee, the boost didn't have any negative effects. Normally after the coffee I have a "crash" so need something to pick me up again, but I didn't experience that at all. Awesome pre-workout.”

“Started trialing the new pre-workout from Bonsai Biotics. I don’t usually use pre-workout’s but this is totally natural, no artificial ingredients and vegan, so I’m giving it a try!This morning I took the pre-workout, then did my mobilization and glute activation before hitting the gym. Personal best on overhead squats so good start I’d say! Felt full of energy, but no crazy high/crash. Perfect!”

Julia Hubbard – Ex Team GB Olympian and Professional Competitive Bodybuilder, Spain

"My trainer let me try some of the Bonsai Extreme Green Pre-workout. I really liked them. They gave me a good even boost of energy. It's certainly not like ones I've had in the past. Extreme Green is clearly meant to give you energy without making you feel crazy pumped. Give them a try."

Nate – Fitness enthusiast, USA

“As a professional runner and athlete I take great care of my well being to stay in the best condition possible. My preparations for the 2016-2017 season started with the help of my coach and mentor, Milos Premceski. He helped me with my general conditioning and cardio, as well as strength exercises. He suggested Bonsai Biotics, Extreme Green Pre-workout to help me through my training. The results have been fantastic, my energy levels have remained constantly high and I felt boosted to do more exercise than normal. On a plus side I have lost a few pounds too, so overall a very good natural product and now a staple in my daily routine”

Aleksander Sac – Professional runner/athlete, Serbia
