The Good Guru Vegan Protein Review

The Good Guru Vegan Protein is a protein powder based principally on plant-derived ingredients. It is available to buy in a couple of different flavours and quantities, and is, as the name suggests, suitable for vegans. It is also gluten free. The main ingredients are not well studied in clinical trials so there is not much evidence available to support the claims made.

The company behind the product, The Good Guru, makes and sells a number of different supplements in capsule and powder form. These come under several categories, including beauty, energy, strength, and weight loss. Some contact details are provided and the company seems to be based in London, England.

The Good Guru Vegan Protein Claimed weight loss benefits

It is not directly claimed on the official Good Guru website that the vegan protein product can help users to lose weight. The product label reads: good for energy and recovery. The official website claims that Good Guru Vegan Protein can help the body stay strong and repair itself. It is added that the product can help maintain muscle mass, aid digestion, reduce inflammation and support overall health. Though not directly claimed on the site, these claims indirectly suggest that the protein powder can help an individual to improve his or her body composition. The suggestion that the product is good for energy and recovery could help users improve exercise performance.

How The Good Guru Vegan Protein Works


The main ingredients in the Good Guru Vegan Protein product are various forms of protein, derived from plant sources. As hinted on the Good Guru website, protein is thought to be beneficial for helping the body to build muscle and recover from strenuous exercise. Protein in general is also believed to have a beneficial impact on body composition, potentially helping the user to lose more fat and maintain more lean mass. The product also contains some herbal ingredients – turmeric and montmorency cherry. These ingredients have some hazy association with weight loss, but have not been proven in clinical studies to have any effects.

How Each Ingredient Works

Pea Protein

Pea protein is thought to work in the same ways as any other source of supplementary protein. There are claims that consuming supplementary protein can contribute to a number of different areas of weight loss, but more pertinently, towards improved body composition.

In terms of weight loss, most links with protein are thought to be indirect. Increasing the protein intake of a person’s diet has been said to be beneficial for suppressing the appetite – it is thought to be a healthy way to fill a person up because it does not contibute much in the way of calories and fat. There has also been suggestion that protein keeps the body feeling fuller for longer after consumption than other forms of macronutrient, potentially helping the user to reduce snacking and portion size at mealtimes.

Taking protein supplements has also been claimed to increase the rate at which fat is broken down for energy while at the same time preventing the breakdown of muscle tissue. This could help to improve the user’s body composition. Protein has also been said to help the user perform at a higher standard – perhaps increasing strength or stamina, thus potentially helping them to burn more calories at the gym.

Protein supplements are probably best known for their use for muscle gain. Protein contains amino acids, which are the ‘building blocks’ of muscle tissue. Taking additional protein may therefore increase the rate at which muscle is repaired and grown when the user is undergoing regular exercise. This association might also help users to recover more quickly from resistance exercise, potentially helping them to workout more regularly.

Finally, if taken with regular resistance exercise, supplementary protein may help the body to become more lean in composition. Muscle tissue uses more energy for maintenance when at rest than does other tissue, like fat tissue, so it is thought that being more muscular means you will have a higher resting metabolic rate. So, indirectly, protein supplements could act as metabolism boosters.

Organic Pumpkin Seed Protein

As another form of protein, this ingredient is thought to work largely in the same way as described for pea protein above. Pumpkin seed protein may contain a slightly different selection of amino acids, helping to provide a more complete range required for muscle growth and repair. As with pea protein, the ingredient may have effects on muscle gain, fat burning, appetite suppression, metabolism boosting, exercise performance, and recovery from exercise.

Organic Sunflower Protein

Another form of protein, organic sunflower protein will perform in mostly the same ways as those described above for pea protein and pumpkin seed protein. Sunflower protein is however also known for containing CLA (conjugated linoleic acid), which may have some benefits of its own.

Montmorency Cherry

There have been links between ‘tart cherry juice’ and weight loss, with some diet plans claiming that the juice can help to ‘trim tummies’ and reduce belly fat. Scientific evidence to support these claims is however not available and it is not clear how the ingredient is believed to work to achieve these claimed results.


Turmeric is claimed to work to boost weight loss in different ways to the other key ingredients, most of which are sources of protein. Turmeric contains a substance called curcumin, which is believed to have a thermogenic effect. Thermogenesis is a term used to describe an increase in the internal body temperature. This change is temperature is said to help the body to perform more optimally; it is thought that it provides a better environment for the enzymes involved in the breakdown of fat molecules for energy, thus helping them to work more quickly and efficiently. It is also thought that thermogenesis can cause an increase in the metabolic rate by making cells work harder and in turn, require more energy to function normally. Again, evidence to support the effects of turmeric on weight loss is not available.

Key The Good Guru Vegan Protein Ingredients

molecular 538

An ingredients list is provided on the official Good Guru Vegan Protein website, but the quantities of each individual ingredient are not disclosed. Whether or not a full list of ingredients and quantities is provided with the product is not known. The key ingredients in the supplement appear to be different types protein, all derived from plant sources (pea, pumpkin seed and sunflower). These ingredients are then supplemented with Montmorency cherry extract and turmeric extract, which are sometimes said to have weight loss effects.

Active Ingredients

Pea Protein

Pea protein is taken from green and yellow peas (legumes sometimes called split peas). The ingredient is sometimes used to enrich foods and supplements with additional protein, which is attained from a plant source and is suitable for vegetarians, vegans, and those who cannot eat dairy products. There have been suggestions that pea protein can help with the treatment of health conditions such as hypertension and cardiovascular diseases. It is also sometimes claimed to have beneficial effects on athletic performance and weight loss.

Organic Pumpkin Seed Protein

Pumpkin is a type of squash, the seeds and oil of which are sometimes used in herbal medicine. The plant has been said to have beneficial effects for health conditions such as bladder and kidney problems, intestinal worms, and benign prostatic hyperplasia. The seeds are also easily found in supermarkets and are sometimes consumed on their own as a snack. The seed contains chemicals that are understood to have a diuretic effect – increasing the frequency of urination.

Organic Sunflower Protein

Sunflower protein is perhaps best known for its conjugated linoleic acid (CLA) content. CLA is a group of chemicals that make up linoleic acid – a form of fatty acid. A certain amount of CLA is consumed by most people on a day to day basis in their normal diets. The ingredient is however commonly used as a supplement. CLA is thought to be useful in the treatment of cancer, atherosclerosis, and some types of food allergy. It is also sometimes claimed to be beneficial in the treatment of obesity because it is said to help with the process of fat burning.

Montmorency Cherry

Montmorency cherry is a form of sour cherry that is grown in certain parts of the world. The sour cherry is a popular fruit for eating and is often the key ingredient in an American cherry pie! Extract of the fruit has also been used to make herbal medicines. The ingredient is claimed to have some beneficial effects for treating gout, insomnia and osteoporosis. It is thought to increase urine production, to help digestion, and to aid muscle pain and damage. Some unofficial sources state that the ingredient contains chemicals that can help to reduce inflammation. It is not a common ingredient in weight loss supplements.


Turmeric is a spice that is commonly found in supermarkets as a flavouring for foods – it is often used in curries. The ingredient is extracted from the root of the turmeric plant and has been used in the treatment of a slection of different health conditions in traditional herbal medicine. For example, turmeric is thought to be useful for helping with gastro-intestinal problems, depression, bronchitis, kidney problems, and arthritis. There is some suggestion on the internet that the spice can help to boost weight loss, but this claim is not backed by any clinical evidence.

Clinical Studies

Clinical Researcher 538

There do not appear to have been any clinical trials undertaken on the Good Guru Vegan Protein as a whole. Some studies have been undertaken on the key ingredients; there are numerous studies pertaining to protein intake and weight loss and body composition, but very few that have looked at the specific plant-derived sources of protein that are present in this product.

A clinical study is a trial performed by scientists to test whether or not a product or ingredient has the properties that it is claimed to have. Clinical studies are typically reliable because they are reviewed by experts before being published in journals online. Nevertheless, some are of better quality than others.

Clinical Studies On Each Ingredient

Clinical Studies on Pea Protein

The potential effects of protein supplementation on body composition and weight loss have been studied fairly extensively in the scientific literature. The effects of pea protein specifically however, have not been well tested.

One of very few clinical studies directly testing the effects of pea protein on body composition factors was published in the Journal of the International Society of Sports Nutrition in 2015. The study was performed using a specific pea protein product and looked at the effects on muscle thickness and strength. The authors compared the effects of the pea protein product on these measures with those of whey protein and a placebo.

For this trial, 161 male participants, all aged between 18 and 35 years, were randomly divided into three groups. The first took 25g pea protein, the second took 25g whey protein, and the third took a placebo for a period of 12 weeks. During this time frame, the participants took their allocated treatment twice a day and underwent a resistance training programme on the upper limb muscles.

Measurements of the biceps muscles were taken before, during, and after the training period and included muscle thickness and strength. At the end of the 12 months, it was found that muscle thickness was increased in all groups and no significant differences were reported between the groups. When only the subjects who were weakest at the beginning of the trial were included, it was found that muscle thickness was significantly increased in the pea protein group compared to the placebo group, with no significant differences between the pea and whey groups. No significant differences in muscle strength were found with the consumption of the different treatments.

Overall, it was concluded that pea protein could be beneficial for increasing muscle thickness in those who are first starting or returning to muscular training. This is when the protein is taken alongside regular resistance exercise. It was added that pea protein seems to be a good vegetable alternative to the more commonly used whey protein products.

Clinical Studies on Organic Sunflower Protein

A few studies have been undertaken with the aim of identifying any potential effects of conjugated linoleic acid (a component of sunflower protein) on weight loss and body composition. One trial, for example, was published in 2001 and looked at the impact of CLA on body fat. For this study, 20 healthy participants took part. It was randomised, double blind and placebo controlled in design. The normal-weight subjects were given either 0.6mg CLA or a placebo three times a day for 12 weeks. During the 12-week period, the subjects did a standardised exercise at the gym for 90 minutes three times a week. Body measurements were taken before, during and after the trial. The results suggested that CLA supplementation could significantly reduce body fat compared to a placebo. Total body weight did not seem to be effected.

A meta-analysis was performed on the effects of CLA on body composition and published in 2007. Meta-analyses are useful papers that use all of the available, reliable data on a topic from various studies to draw more stable conclusions. This paper aimed to determine whether or not CLA supplementation could help in reducing fat mass in humans. The authors searched relevant scientific databases for papers on the topic that were performed using randomised, double blind, placebo controlled methods and measured body composition. They found 18 studies that fitted the criteria, three of which looked at isomers. It was concluded that CLA could have a slight effect on body fat loss in humans when taken at a dose of 3.2g per day.

Clinical Studies on Turmeric

Though very few clinical trials have been performed to look at the effects of turmeric on weight loss, a small number of preliminary studies are available that have looked at one of the active chemicals present in turmeric – curcumin.

One such study was published in 2015. This trial looked at the impacts of curcumin on weight loss and fat stores. The study was randomised and controlled, using overweight subjects, all of whom had metabolic syndrome. Forty-four participants were involved in the study, who had lost weight during 30 day period of diet and lifestyle changes. The subjects were then given either curcumin with phosphatidylserine or pure phosphatidylserine for a further 30 days and various body measurements were taken. The authors concluded that curcumin may increase weight loss and fat loss, as well as reduce waistline and hip circumference. It was noted however that these findings are preliminary and further study would be required to confirm any effects.

A review study published in Nutrition Reviews in 2011 considered the effects of turmeric and specifically curcumin on weight loss. The authors found that curcumin may have a beneficial effect in regulating the metabolism of fats and in turn, might help to control the development of obesity and related factors.

The Good Guru Vegan Protein Side Effects

Woman With Stomach Ache  538

Though stating that the product should not be taken by pregnant or breastfeeding women and that all customers should consult a practitioner before taking the supplement, the Good Guru Vegan Protein website does not mention any potential side effects associated with the supplement. While none of the ingredients are well known for causing severe side effects, it is important to note that some do come with side effects and some are understudied in clinical trials, meaning that their potential negative effects may not be known. The official website fails to disclose the quantities of each ingredient in the product, making it more difficult to determine whether the ingredients may have any effect on the user.

Side Effects Associated With Each Ingredient

Side Effects associated with Pea Protein

The clinical study on pea protein described in the ‘clinical studies’ section above did not highlight any side effects relating to the ingredient. Apart from this, there is very little information available on the potential safety and side effects of pea protein. Very few studies have been performed on the ingredient so we would not recommend it be taken by individuals who are pregnant or breastfeeding. If you have a medical condition, we recommend that you consult a doctor before taking pea protein supplements. Taking too much protein can cause side effects such as increased bowel movements, reduced appetite, cramps, bloating, nausea, thirst, tiredness and headaches. It has been suggested that these side effects might be worse when you first start taking a protein supplement, and that they may reduce as your body gets used to the extra protein intake.

Side Effects associated with Organic Pumpkin Seed Protein

In the amounts consumed as food (as pumpkin seeds often are in places all round the world), pumpkin seeds are thought to be safe and have not been linked with any side effects. In higher doses, like the amounts found in herbal medicines and supplements, the safety of pumpkin seeds is not so well known. There has been suggestion that it may cause ejaculation problems in some men. Due to a lack of research, it is recommended that pregnant and breastfeeding women avoid taking high doses of pumpkin seed extract.

Side Effects associated with Organic Sunflower Protein

The same side effects are possible with sunflower protein as are for the other sources of protein described above. Looking specifically at the CLA content of sunflower protein, it is considered ‘possibly safe’ when takenin medicinal amounts. CLA is found in many common food sources that are included in most peoples’ daily diets; in these amounts it should not therefore cause any notable side effects. In higher doses however, CLA has been associated with side effects such as nausea, diarrhoea, upset stomach and dizziness. Due to a lack of long-term studies of the ingredient in pregnant women, it is not recommended that these individuals take CLA supplements in the long term. The same goes for breastfeeding women.

CLA may impact blood clotting so should be avoided by anybody with a disorder that stops their blood from clotting properly and those who have surgery scheduled in the next two weeks. It is recommended that those with diabetes or metabolic syndrome also avoid the ingredient.

Side Effects associated with Montmorency Cherry

Cherry is thought to be safe for most people when consumed as a food, but a lack of clinical studies on the ingredient means that its safety in supplementary amounts is not known. Due to this lack of understanding, it is recommended that pregnant and breastfeeding women avoid taking large doses of Montmorency cherry.

Side Effects associated with Turmeric

Turmeric is generally thought to be safe for intake by mouth by most people of good health; there are however some effects that users should be aware of. In some rare cases, turmeric has been linked with diarrhoea, stomach upset, nausea and dizziness. WebMD also reports an individual suffering from severe heart problems after taking very high doses of turmeric (1500mg turmeric twice a day), though it has not been proven that turmeric was the cause of the problem.

It is thought to be ‘likely safe’ for use during pregnancy and breastfeeding in the amounts commonly consumed in food, but may not be safe when taken in medicinal amounts for these groups. It is not recommended that you consume turmeric in medicinal amounts if you have any of the following health problems: iron deficiency, diabetes, bleeding problems (or surgery scheduled in the next two weeks), gallbladder problems, gastroesophageal reflux disease, or hormone-sensitive conditions. Turmeric might also reduce fertility. Avoid taking supplementary turmeric if you are prescribed medications that slow blood clotting.

How To Use

Woman With Pills 538

It is stated on the official product site that four scoops of the powder should be added to 400ml of water and the mixture shaken. It is stated that there are 12 servings per 500g, and that a serving is approximately 40g, which according to the nutritional information, should contain 27.04g protein. No quantities are disclosed for the different sources of protein or any other ingredients in the supplement.

The shake is vegan and free from gluten. Though it does not contain any nuts, it is not made in a nut-free environment. It is added that the product should be taken on the advice of a practitioner or pharmacist, and that it should not be taken by pregnant or breastfeeding individuals. A warning is added not to exceed the recommended dose and that food supplements should not be used to replace a balanced diet and healthy lifestyle.

Based on the ingredients list (and the lack of disclosed ingredient quantities), we would recommend that all users with a health condition consult a doctor before taking the Good Guru Vegan Protein shake. Not enough studies have been performed on most of the ingredients to know whether or not they may cause complications for people with certain health problems.

Overall Verdict

The Good Guru Vegan Protein is a shake suitable for vegans and those who don’t eat gluten. It offers protein from a selection of plant sources and does not contain any ingredients that are associated with severe side effects. The plant protein ingredients have not however been well studied in clinical trials so there is little direct evidence that the product will work to aid weight loss or improved body composition.
