Soy Protein Isolate 90 is high in protein and low in fat. It is the perfect protein source for both vegans and vegetarians and those with a dairy intolerance. It is ideal for building quality muscle and is instantised to ensure easy mixing.


How is Soy Protein Powder Made?

Soy Protein Isolate 90 is the most refined form of soy protein, isolated from the soya bean which is then defatted and most of the carbohydrates removed. The soya bean is a legume that contains no cholesterol and is naturally low in saturated fats. Soya beans are the only vegetable that contain all EIGHT of the essential amino acids. Isolated soya protein is easily digested by the body with a digestible rating of 95-98%.

If you follow a vegan diet, Soy Protein Isolate 90 is considered a nutritionally complete protein and can help provide the essential vitamin B12, which is only found in animal proteins. This is based on thousands of studies but notably research published in The Current Sports Medicine Reports that focuses on vegan and vegetarian athlete’s diets.

Chocolate Peanut Cookie

- 07 February 2017

Just bought 4kg of vegan protein. Use this because it's better and doesn't bloat me like whey. Absolutely delicious stuff! Incredibly thick which I love and I use it with Greek yogurt, hazelnut milk & chia seeds to make a mouth watering pudding!!! Amazing product and great company! Thank you :)
Pleasantly suprised

- 05 February 2017

Decided to give shakes a go to help curb my appetite and improve my metabolism rate to help weight lost. So far order "vanilla creme" not very nice, taste better with coco added, recently order "mint brownie" very nice! Having a shake a day at lunch time and I've stopped excessive snacking so its a win!
Excellent alternative

Couldn't rate this product enough. Easy on the stomach for those that are unable to tolerate whey. I love the consistency, it's slightly thicker than whey. Vanilla is very nice.
Really good!!

As an IBS sufferer whose symptoms are triggered by dairy, this product is a godsend!! So far i've tried the Caramel macchiato and the Choc peanut cookie - both are good, but my favourite has to be the caramel macchiato. I initially tried both just mixed with water, but I think they taste too artificial that way. far better mixed with almond or soya milk. I use unsweetened almond milk - which at 13cals per 100 mls, isn't exactly going pile on the calories when I use 300mls and a scoop of powder. Also, I think when added to milk, it keeps me fuller a lot longer. Currently I'm having a shake when I get up and another after exercise - which us usually about 6pm. i'm still eating 3 meals a day, but my snacking in between meals is now almost non existent. Which is great - i'm one of those people that is permanently hungry, but not now - I can't tell you how fab that feels - my stomach has stopped rumbling!! As for weight loss/gain - I have been on my 'two shakes a day regime' for about a month now and the scales haven't really moved one way or the other - but that doesn't bother me, what has improved though is my recovery, muscle definition and feeling fuller for longer, which at the end of the day, is what I was hoping for. ive just put in another order for the vanilla - fingers crossed its as good as the other flavours!!
Great vegan protein

- 03 September 2016

Been using the Protein Works Whey protein for awhile but have recently turned vegan & was looking for a decently priced vegan protein. This certainly fits the bill; decent price, good flavour & completely free of dairy. It has a much softer, finer structure than Whey Protein (my scoop literally sinks into it) but blends just as well.

Have noticed there are numerous options for vegans on the site so will definitely try others, but would be perfectly happy to purchase Soy Protein 90 again.

Q. When should I take Soy Protein Isolate?

A. It depends upon your lifestyle and goals, we recommend the following optimal serving times: Immediately upon waking / 30 minutes pre workout / immediately after your workout / before you go to bed. Any other time during the day when you require additional protein intake.

Q.What does Soy Protein Isolate taste like?

A. Soy Protein Isolate has a neutral vegetable taste, and is considered the cleanest tasting vegetable protein available.

Q. How much protein should I take?

A. It is recommended that you consume between 3-5 servings per day, dependent upon your own personal needs. A serving would be classed as 30g (one scoop) of Soy Protein Isolate 90. It is recommended that you take 1g of protein per pound of body weight, so adjust your intake accordingly.

Q. Why do I need to take protein?

A. Consuming a protein shake can help promote muscle growth. It has been widely researched and shown to help muscle growth, recovery and repair after intense exercise or workout.

Q. Is all Soy Protein Isolate the same, regardless of which brand it is?

A. As with so many things in life, if you don't ask the right questions, you won't get the right answers! The quality of protein can vary significantly and therefore the protein content will do too. In addition, just because a product may be called Soy Protein Isolate it doesn't mean that it only contains soy protein isolate. We recommend you read the ingredients and nutritionals on the label to better understand exactly what you are buying. We can assure you that our Soy Protein 90 is purely soy protein isolate. At TPW™, we are committed to transparency and openness in all our products and that is why we provide a Product Profile, Protein Insight and Product Testing on this product.

Q. How can I tell if the protein I use is a good quality protein?

A. Key signs to look for are the level of protein declared on the label. Look for soy protein isolate with a minimum 90% content.

Q. What does "dry basis" and "as-is" mean when talking about protein content?

A. When you see a protein powder that states on the label the protein is given as "dry basis " this means that the moisture present in the powder is included in the total protein value. Moisture in dry protein powders are typically around 4%. However, when a protein supplement is stated "as-is" this means the actual protein content of the powder with the water content excluded. In other words, the true protein you will be consuming. As protein prices have increased significantly over recent years due to the large demand in the sports nutrition sector, some brands may not give you all the facts in regards to the true level of protein in their products. At TPW™, we believe in transparency to give you the utmost confidence when choosing your whey protein supplements. On all our protein products you will see both the as-is and dry-basis values declared. Once again, it's all about knowing what to look for.

Q. Is Soy Protein Isolate suitable for vegans and vegetarians?

A. Yes, it is suitable for both vegans and vegetarians and those with a dairy intolerance.

Q. What is Soy Protein Isolate made from?

A. Soy Protein Isolate is derived from soya beans.

Q. Is Soy Protein Isolate absorbed as quickly as whey protein?

A. Soy Protein Isolate powder is considered a slow to moderate release protein, so is ideal to use alongside other protein sources.

Q. Can I take Soy Protein Isolate with other supplements?

A. The simple answer is yes. We recommend you always check serving instructions on each product if you plan on taking a combination of supplements. Soy Protein Isolate is most commonly taken with creatine, oats, iBCAA and glutamine.

Q. Can I take too much protein?

A. If you don't burn the excess calories that come with the additional protein, it may lead to increased body fat. No other side effects have been noted.

Q. What if any side effects will I get from taking Soy Protein Isolate?

A. We haven't heard of any nasty side effects from taking our Soy Protein 90.
