Laboratory-controlled scientific experiments, carried out on human subjects, specifically plant-based people (Creatine and Taurine are not found in plants, so neither vegans nor vegetarians consume any in their diet) have recorded significant boosts in working intelligence, brain processing speed and memory in subjects supplementing with creatine, as compared to placebo/control groups.
Taurine has been found to exhibit numerous neuroprotective qualities, (helping to prevent degeneration, damage and impairment of brain cells) and may aid in the growth of new neurons, (the cells of the brain and nervous system).
A Magnetic Resonance Spectroscopy (MRS) experiment on the brains of human subjects supplementing with Creatine found that supplementation increased Creatine content in the brain, specifically in grey matter (+4.75), white matter (+11.5%) the cerebellum (+5.4%) and thalamus (+14.6%).
Because Creatine supplementation increases levels of Phosphocreatine in the body, which is essential in the formation of ATP (Adenosine Triphosphate, the "energy currency of the cell"), it is very possible that this increased energy available to brain cells is the reason for the increased cognitive abilities measured in human subjects in experiments on working intelligence and memory.

Aging, on a biological level, is partly driven by the accumulation of damage to the skin, and all cells in the body from chemicals called “free radicals”, which cause oxidative stress, leading to wrinkles and other internal and external signs of aging. Antioxidants neutralize free radicals, thus helping the body to protect cells from free radical damage. All three amino acids in Vegan Brain Food have powerful antioxidant properties, protecting different areas of the body.
The human body’s natural, internal production of Creatine, Taurine and Carnosine* declines with age, and is measurably lower among those who do not eat animals. Human-based laboratory experiments have demonstrated the effectiveness of dietary supplementation in increasing the levels of these important amino acids within the brain and body.
An experiment conducted on human skin tissue, (in a cultured medium) found that Carnosine has the potential to reverse signs of aging within skin cells.
*The human body synthesizes Carnosine from Beta Alanine and the amino acid Histidine, which is commonly found in plant-based foods, including beans, nuts, seeds & whole grains.

A recent peer-reviewed study in the European Journal of Immunology labelled Taurine an “an energy drink for T cells” that play a central role in the human immune system. Creatine helps recharge the “molecular battery” (mitochondria) of immune cells, energizing their ability to protect the body from both internal and external threats.
NOTE: While there is lots of promising research on the immune-boosting potential of these amino acids, Vegan Brain & Body Boost is not intended to treat or cure any disease. However, if you'd like to review some of the current research on this topic see additional sources below.

Taurine has been found to increase the fat burning results of exercise, and increase the burning of lipid fatty acids (Triacylglycerols) at rest, even independent of exercise.
Increased muscle mass improves our Resting Metabolic Rate (and with it the amount of calories we burn while sitting, sleeping etc.) Due to Creatine's ability to energize muscle cells, and fuel significant gains in strength and muscle tissue (see "Physical Fitness + Energy" section below), a *combination* of Creatine supplementation and any form of resistance training that increases muscle mass (this doesn't just apply to lifting weights, but also to cycling, squats, lunges, sports or any type of intense physical activity) can help increase our Resting Metabolic Rate, and fuel fat loss, even if one's overall weight (measured in pounds) may go up due to muscle tissue being heavier than fat tissue.
A reduction in muscle tissue as we age may be one of the contributing factors to a decreased Resting Metabolic Rate, and accompanying increase in body fat. By virtue of it's ability to aid in resistance training, Creatine can help preserve muscle tissue as we age, and maintain a healthy metabolism, and healthy body fat ratios as a result.
A *combination* of HIIT (High Intensity Interval Training) and Beta Alanine supplementation has been found to improve lean body mass composition in experiments on human subjects, by improving peak performance during exercise. It must be stressed that, unlike Taurine, which has been found to have potential fat-burning qualities independent of exercise, the benefits of Beta Alanine supplementation were only quantified in human subjects in the context of HIIT training. Anyone interested in living a long and healthy life should look into the benefits of HIIT training, arguably the most beneficial form of cardiovascular exercise.

Taurine has been found to increase exercise performance and endurance, can assist in muscle recovery following exercise, reduce oxidative stress following exercise, and aids in the replenishment of glycogen in muscle fibres after exercise.
Beta Alanine supplementation has been found to increase Carnosine levels in the body, and can help improve lean body mass, reduce muscle fatigue and increase high intensity aerobic exercise performance.
Dozens of scientific studies have recorded significant gains in strength and performance in athletes supplementing with Creatine. But Creatine alone will not make you stronger. What it will do is help improve the production of ATP, the “energy currency of the cell,” fuelling your body’s potential to push harder and longer in all energy-dependent activities.
Due to the absence of Creatine in the diets of vegans and vegetarians, plant-based people have lower average levels of Creatine in our muscles, and register increased benefits from Creatine supplementation, as compared to animal eaters.
Creatine supplementation was also found to reduce some of the negative cognitive effects of sleep deprivation, resulting in reduced cognitive impairment and improved mood. But please note: we are not suggesting this supplement be used as a substitute for getting a good night’s sleep. There is no substitute for a good night’s sleep. The basic fundamentals of good health are: a whole food, plant-based diet, regular exercise, good sleep, regular stress management and relaxation. This supplement is not meant to be a substitute for any of those things, it is simply meant to literally supplement and improve a healthy lifestyle, not to encourage reduced sleep or any other bad habits! If you’re reading this and it’s late, keep the tab open, go to bed and resume tomorrow :)

Taurine, Creatine and Beta Alanine, as potent antioxidants, play important roles in counteracting oxidative stress, the management of which is a key factor in both female and male sexual health. Taurine and Creatine are naturally concentrated in the male and female reproductive organs, brain, spinal cord, eyes, heart and white blood cells of the immune system.
Unlike psychological stress, which can be counteracted using numerous relaxation techniques, oxidative stress inside our cells that is caused by physical substances, such as environmental toxins we are constantly, involuntary breathing, drinking and eating, can only be counteracted by physical antioxidants (see diagram above in the anti-aging section to get a great visual explanation of the role of antioxidants in the body).
While a plant-based diet is naturally rich in antioxidants, Taurine and Creatine are only found in the flesh of animals, so the only way for vegans and vegetarians to obtain their specific antioxidant benefits is to add supplemental aminos to our cereal, oatmeal, smoothies, juices etc.
Taurine has long been recognized as a potent cytoprotective compound (providing protection to cells against harmful chemicals and other external agents), and as such can assist the body’s natural detoxification of dangerous heavy metals that we are constantly, involuntarily exposed to in our toxic, fossil-fuel based society.
Taurine may also play an important role in human vision/eye health and reducing blood pressure.

All of the amino acids in Vegan Brain & Body Boost are already present in your body, made by your body (albeit in smaller quantities than could be obtained than by eating the bodies of other animals). The goal of this supplement is simply to take advantage of their beneficial attributes, without killing any animals.
Thanks to science it is now possible to "have your cake and eat it too", that is to obtain the benefits of these aminos without consuming dead animals, which would come along with negative side effects including cancer-causing carcinogens, pro-aging Advanced Glycation End Product (A.G.E.) compounds, pro-inflammatory toxins, cholesterol, animal abuse, killing and global ecological destruction. Plant-based diets have been found to drastically reduce one's chances of dying from the two leading causes of death in the Western World: cancer & heart attacks.
Creatine has been harnessed by athletes for decades, and is one of the most thoroughly studied supplements on Earth. Decades of scientific research, including long-term studies of subjects supplementing with 6x the amount of Creatine that is in 1 serving of Vegan Brain & Body Boost, have yielded no major negative results, while quantifying the positive results listed in the various sections above.
Human clinical trials have also demonstrated the safety of Taurine and Beta Alanine supplementation at levels higher than are found in Vegan Brain & Body Boost.
Those with medical conditions should consult a doctor before taking this supplement. This supplement is designed for adults and is not intended for children.

Vegan Brain & Body Boost has no artificial flavours or additives, is essentially tasteless and will simply blend in with the flavour of whatever fruits you choose to put in your smoothie/shake/oatmeal/cereal.
The most important thing to remember when taking this supplement (and in life in general) is to drink lots of water throughout the day.
One great way to make sure you are well hydrated every day (and to lose weight, live longer and improve various bodily functions) is to obtain some of the benefits of intermittent fasting by not eating breakfast as soon as you wake up, but instead making sure you drink 2+ glasses of water in the morning before breakfast. Postponing your first meal by a few hours takes advantage of the fact that you're obviously not eating while you're asleep, and will help you obtain some of the numerous benefits of intermittent fasting, which you can and should maximize by also not eating right before bed.
If left in water, over the course of a day Creatine will gradually break down into a harmless, but useless molecule called Creatinine. To get the most out of this supplement it is best to mix it into your smoothie/shake right before you drink it, or within a few hours of when you plan on drinking it. If you like to make your smoothies/shakes at night that's fine, just make it as you usually do and then stir/shake/mix the Vegan Brain & Body Boost into it in the morning.
NOTE: In the interests of reducing pollution no plastic scoop is included in each container, nor is any desiccant - that little package of silica balls that also ends up straight in the trash/ocean. This means means that ambient moisture may eventually lead to little clumps of powder being stuck together in the container. This isn't something to worry about, just break them up with a spoon or put them straight into your shake and they'll break apart on their own.
Serving Size: 1.8 Teaspoons (7.5g)
+
Is this basically 2 Teaspoons? Yes, yes it is. If you use 2 Tsp instead of 1.8 you'll get slightly more benefits from this supplement, but a container may last you a day or two less. Either way, the main point here is to reduce plastic waste. On that note, the container is fully recyclable, so make sure to do so!
Recommended dose: 1-2 Servings (1.8-3.6 Tsp)/Day, depending on levels of intellectual and physical activity. Yes that's right, the brain uses larger quantities of energy when doing difficult mental tasks (or just when staying awake longer than it should). Despite being only 2% of the body's weight, the human brain uses 20% of available energy. If you are having two servings a day it would be best to break it up into two meals/drinks, at different times of day.
These aminos take time to be absorbed into the brain and body, and build up to levels that reap the results found in the experiments above. For faster results start with 2 servings (3.6 Tsp)/Day, ideally broken up into two meals, and then settle into whatever dosage amount makes sense for your lifestyle.
