Pulsin Whey Protein Review

There are several different whey protein products sold by Pulsin. The company sells whey protein isolate powder, whey protein concentrate powder and organic whey protein concentrate powder. The key ingredient in each of these products is whey protein and this is not supplemented with any other active substances. The non-organic products contain soya lethicin – an additive that should act as an emulsifier.

We will discuss the differences between whey protein concentrate and whey protein isolate in the section below, but the ingredients are both attained from the same source and will generally have the same effects. Whey protein is commonly used as a muscle building supplement and might help to improve body composition when taken alongside regular resistance exercise.

Pulsin Whey Protein Claimed weight loss benefits

The official Pulsin website does not make any suggestion that the whey protein powders can help users to lose weight or gain muscle mass. The products are advertised as a source of protein that can easily be added to your own recipes to bolster your daily protein intake.

Whey protein has however been used in weight loss and athletic performance supplements in the past. The ingredient is believed to help muscles to repair and grow following intensive exercise. It is also said to have beneficial effects on body composition and to help burn fat. Finally, whey protein has been used as an appetite suppressant in supplements.

How Pulsin Whey Protein Works


Though the official Pulsin website doesn’t mention any potential weight loss benefits associated with their whey protein powder products, they key ingredient in all of these powders – whey protein – has been linked with body changes in the past. Supplementing whey protein whilst undertaking a regular intensive exercise regime has been said to help the body to recover from strenuous exercise and increase muscle mass. In turn, whey protein has been linked with improving body composition and potentially acting as an appetite suppressant. Protein is also thought to be a healthy way of filling the user up – helping to suppress the appetite following consumption.

How Each Ingredient Works

Whey Protein

Whey protein contains a range of amino acids, which are the building blocks of protein (and therefore of muscle tissue). Taking whey protein in supplement form is therefore thought to help the muscles to recover from exercise by providing amino acids to help repair torn tissue. Whey protein is also believed to help the muscles to grow – but only if it is taken at the same time as regular exercise.

In terms of weight loss, it has been suggested that whey protein is thermogenic. There is no solid evidence that whey protein supplementation can aid weight loss, but when taken alongside regular exercise, whey protein is thought to increase fat loss whilst maintaining muscle mass. It is sometimes said to have a thermogenic effect – increasing the internal body temperature and in turn, helping the enzymes involved in the breakdown of fat cells to work more efficiently.

Finally, whey protein has been described as an appetite suppressant. Protein is a healthy macronutrient that does not contain much in the way of calories/fat (though the fat content may vary depending on whether you are looking at they whey protein concentrate or whey protein isolate product). It is thought to help keep the user feeling full and so prevent snacking without contributing a large amount of calories to the diet.

Key Pulsin Whey Protein Ingredients

molecular 538

An ingredients list is available on the Pulsin website for each of the whey protein powder products on sale. Each of the products contains its consecutive source of whey protein (either whey protein concentrate or whey protein isolate) as the main ingredient. Apart from the Organic Whey Protein Concentrate product, they also all contain soya lethicin; this is not an active ingredient but instead is said to act as an emulsifier. A breakdown of nutritional information is also provided on each product site.

Active Ingredients

Whey Protein Isolate

Whey protein isolate is an ingredient extracted from whey – a by product created during the process of cheese making. Whey is one of the most commonly used sources of protein for health supplements. Whey protein isolate is an isolated form of the ingredient; the Pulsin Whey Protein Isolate product contains 93% protein. To make whey protein isolate, more carbohydrates, fats, and lactose is removed from the substance. This ingredient is therefore more suitable for users with lactose intolerance that whey protein concentrate, though it may still contain some lactose.

Whey Protein Concentrate

Whey protein concentrate is also made from cheese derived whey. This version is usually slightly cheaper than whey protein isolate. The difference between whey protein isolate and whey protein concentrate lies in the manufacturing process. Whey protein concentrate contains more fats, carbohydrates, and lactose than whey protein isolate. The whey protein concentrate products that are made by Pulsin contain less protein than the isolate product; the non-organic version contains 82% protein whilst the organic version contains 75% protein.

Clinical Studies

Clinical Researcher 538

None of the three whey protein products sold by Pulsin appear to have been subject to any clinical testing. However, the key ingredient in each of the products is whey protein (in concentrate or isolate form) – the protein powders do not contain any other active ingredients. Whey protein has been tested for its potential effects as a weight loss, muscle building and athletic performance supplement, so the results of those trials are directly relevant to these products.

A clinical study is a means of testing the effectiveness and safety of a product or ingredient. Reliable trials are usually performed in controlled conditions, looking at the effects of the active substance compared to a placebo.

Clinical Studies On Each Ingredient

Clinical Studies on Whey Protein

Whey protein is one of the most commonly used sources of protein for dietary supplements – like weight loss beverages and athletic performance powders. Whey is also the best studied source of protein. It has been tested for its potential effects on the body in terms of body weight, fat mass, muscle mass and athletic performance.

One study published in 2008 looked at the effects of whey protein on weight loss. The trial was randomised and double blind; participants were given either a whey protein supplement or a control beverage containing the same amount of calories 20 minutes before breakfast and 20 minutes before dinner every day for 12 weeks. An array of body measurements were taken throughout the study and blood samples were taken before and after the trial.

The data were analysed and the results indicated that those in the whey protein supplement group did not lose significantly more weight than those in the control group. Whilst overall body weight was not significantly changed with whey protein intake, those consuming the protein supplement did lose more body fat and less muscle mass compared to those taking the placebo. It was concluded therefore that whey protein might be a beneficial supplement for boosting fat loss and improving body composition when taken alongside a very low-calorie diet.

A study published in the Nutrition Journal in 2013 looked at the effects of whey protein isolate supplementation and rice protein isolate supplementation on recovery and body composition. Twenty-four young males were involved in this trial; they were randomly divided to receive 48g of rice or whey protein isolate three days a week for eight weeks. On each of the three days that the subjects consumed their treatment, they also underwent a resistance training session. The protein supplements were taken immediately after they completed the exercise and a range of measurements were taken throughout.

The results of the study suggested that both whey protein isolate and rice protein isolate supplementation immediately after resistance exercise could help to improve body composition and exercise performance. The authors did not note any differences between the effects of the two treatments.

Another study, published in 2013, aimed to investigate the impacts of whey protein supplementation on the body when taken at the same time as users undergo a resistance training programme. The participants were both male and female subjects who were not resistance trained. The 63 individuals involved in the trial were split into three groups, who received whey protein, soy protein, or a carbohydrate control on a daily basis for nine months alongside a resistance training programme totalling 96 workouts. Body composition measurements were taken before, during, and after the trial.

Results indicated that taking whey protein alongside a resistance training programme could help previously un-trained individuals to gain lean body mass. The effects of whey protein were significantly greater than the effects of soy protein or a carbohydrate control, suggesting that the quality of the protein supplement has an effect on how beneficial protein supplementation is for muscle gain.

A review study was published in 2008; the authors of this paper looked at the effects of whey protein on muscle mass, but took a slightly different angle. The authors aimed to investigate whether or not whey protein supplementation can have an impact on sarcopenia – the wasting of skeletal muscle that occurs with ageing. The review paper looked at a number of studies on the topic and based on their results, concluded that supplementing with whey protein could help to improve the maintenance of muscle mass, which in turn could improve quality of life and reduce the overall burdon of certain diseases.

A meta-analysis on the topic was published in the Journal of the American College of Nutrition in 2014. This study looked at the effects of whey protein supplementation on body composition when taken with or without resistance exercise. The authors identified randomised, controlled trials that involved healthy adults as participants and tested the effects of whey protein concentrate, isolate, or hydrolystate. A range of statistical analyses were undertaken on the combined results of all the relevant identified trials – a collective sample of 626 participants from 14 studies.

The results of the statistical tests suggested that whey protein supplementation could improve body weight and body fat loss. Whey protein was also seen to increase lean body mass when taken at the same time as a resistance exercise programme. It was concluded that whey protein could be a useful supplement for weight loss, weight maintenance, or improving body composition.

Overall, the results of scientific studies to date have indicated that whey protein supplementation may be beneficial for improving body composition (reducing fat mass whilst maintaining or gaining muscle mass), particularly when supplementation is combined with regular resistance exercise. It should be noted however, that most of the studies on the topic to date have been low quality and typically involved small sample sizes; before a firmer conclusion can be drawn, more high-quality studies involving large groups of participants should be undertaken.

Pulsin Whey Protein Side Effects

Woman With Stomach Ache  538

The official product website does not mention any potential side effects associated with any of their whey protein powder products. There is also no mention of groups of people who should not take the supplements. Nevertheless, the key active ingredient in each of these, whey protein, has been associated with some side effects. These effects are generally mild and may not persist. There are some groups of people who should be cautious about taking whey protein supplements; if you are unsure whether or not whey protein supplements might be suitable for you, we recommend that you consult a doctor before trying the Pulsin whey protein products.

Side Effects Associated With Each Ingredient

Side Effects associated with Whey Protein

Whey protein is believed to be safe for use by most people – children and adults alike – when taken in moderate doses. Protein supplements are not thought to be unsafe but it is recommended that you stick to the recommended dose (the Pulsin website recommends 10g protein powder per serving). Some mild side effects are sometimes reported by whey protein supplement users; these tend to be related to the gastrointestinal tract. Examples include: increased bowel movements, stomach pain or discomfort, diarrhoea, nausea, bloating, and reduced appetite. These may be more likely when the user first starts to take a protein supplement and some people report that the side effects reduce or stop completely once the user’s body gets used to the supplementary protein intake. Other potential side effects include headaches, increased thirst and tiredness.

If side effects persist for prolonged periods of time (weeks or months) or if you experience any severe side effects, it is recommended that you stop taking the protein supplement and consult a doctor. Whey protein is not suitable for people with an allergy to cow’s milk. There is not yet enough information to state whether or not whey protein is safe to supplement when you are pregnant or breastfeeding, so it is recommended that these individuals avoid use. Consult a doctor before taking whey protein if you are taking any medications; the ingredient can affect certain drugs. Whey protein supplementation might significantly reduce the effectiveness of levodopa. It might also impact the effectiveness of alendronate and some antibiotics.

How To Use

Woman With Pills 538

The official Pulsin websites for each of the whey protein products do not offer any details on how the product should be used. There is no mention of how much of the protein powder should be taken, when it should be taken, or how regularly. A serving size is described as 10g and it is noted that the protein can be added to a range of foods and drinks, like smoothies, porridge, juices, soups, or pancakes. In their most raw form, protein powder is usually used to make a shake by adding it to water or milk.

As mentioned above, supplementing whey protein is not recommended for pregnant or breastfeeding women due to a lack of reliable information on the intake of whey protein in these individuals. The whey protein products might also not be suitable for those who have a digestive condition such as irritable bowel syndrome. Avoid the products if you are taking levodopa and consult a doctor before taking them if you are taking alendronate or antibiotics. Do not take any of the whey protein supplements if you have an allergy to cow’s milk. If you are lactose intolerant, the products might upset your stomach; whey protein isolate contains less lactose than whey protein concentrate and so might be the better option for this group of people.
