What’s the best type of milk to mix with The Slender Blend?

It’s down to your personal preference! We only advise almond milk as a mixer as it has the best nutritional profile of milks and plant - based milks. You are free to use whichever milk you choose - cows, oat, almond, soya, coconut or even water. Please bear in mind the taste and texture may vary slightly depending on which alternative you choose. Also cows milk can have a high fat and sugar content so if you're looking to lose weight this may not be the best choice for you.

I’m pregnant, can I have The Slender Blend?

The Slender Blend is fine to have during pregnancy. The reason we advise caution towards The Slender Blend when pregnant or breastfeeding is because this does contain about 33% of your RDA vitamin A and about 30mg of caffeine. Vitamin A and caffeine amounts should be limited during this time, which is why we recommend sticking to only one shake per day and in some cases also consulting with your GP who looks after you during your pregnancy/breastfeeding. There are no other such ingredients which will cause any harm to your baby. We advise not using it as a meal replacement and merely a low calorie snack as it's important to remember to not put too much pressure on yourself to lose weight and try to enjoy this time with your little one! You'll definitely need the energy with a newborn!

What’s the difference between Slender Blend and WPC/WPI

The main difference between the Slender Blend and the WPC/WPI is that the Slender Blend is a meal replacement and the WPC is not. The Slender Blend contains 26 added vitamins and minerals and pre and probiotics needed to sustain replacing a meal and keep your gut healthy. The WPC however is a pure whey protein shake to give you a protein hit after a workout or as a snack. If your main goal is weight loss The Slender Blend would be more suited to your needs.

Great service

I’ve been using Protein World products for a few months now & order on a regular basis. I ordered the granola this time for a change & another pack of slender blend. Both are good quality however annoyingly once I placed my order I received an email with a higher discount than the one I received with my order.

Vanilla ice cream, strawberries and cream and vanilla caramel delight are absolutely delicious sweet but not sickly love these highly recommend them especially if you have a sweet tooth lol me
Tried other brands and this is definitely the only protein powder I would ever use
Also the caramel protein bars are delicious best I’ve tasted and just like a chocolate bar but better
