It's fibre - helps with fibre needs! Separates from shake after sitting still for a while, but once you shake it again you can't tell on drinking. Has a pretty neutral taste so goes with anything. Put it in a heavier shake though, not a watery preworkout.
Goes Well With:
Protein shakes, mixed into food like porridge.

I quite like the taste, sweetish and apple-y. Mixes well with creatine and whey. Delicious with oats and fruit.  Seems to help with digestion and regularity. Would recommend.

Fibre does the trick, taste isn't great but benefits outweigh the negatives

Like many of the other reviews I would agree that the consistency of this powered is awful & it is far from flavourless (it’s pretty rank). However , the main thing is that it does work! I’ve tried to mix it in my coffee- ewww. I’ve found the best way to take this is mix 2 scoops with about 100ml of boiling water so it dissolves. Add 1tsp of honey & some lemon. The lemon really breaks down the bitter flavour. I wait for it to cool & shot it.

All lot of people commenting abut it being lumpy after mixing I've discovered the best way to mix is to add it to your protein shake ,leave in the fridge for 30mins then shake again ,no more lumps Excellent product to keep y ou moving

Protien shake

Summery in one. It’s like you throw a Jerry can of petrol onto your metabolism fire! Don’t get me wrong you need to give it a week to fully kick in. Taste wise god knows. I blend it every morning a tea spoons worth with my chocolate nut protein and a scoop of vitamin C and nutri greens. The benefits are amazing. 2/3 bowel movements a day. You feel lighter and can see a difference in complexion after around 14 days. Fantastic product 
Goes Well With:
Protein, nutri greens, and Andrex 

I purchased this as it was cheaper than another well know supplier. I mix 2 scoops every morning with my meal replacement shake. It mixes really well and it doesnt change the taste of the drink you are taking it with. Highly recommended to get your fibre intake up. 5 stars for me and will purchase again. Also bag will last a long time
Goes Well With:
Protein shakes or meal replacement shakes. Not tried it with just water.

I love this product I put it my protein mix and mixes well with that a really easy way get get daily dose of fibre as I have allergies to a lot of fruit. I have tried another more expensive product elsewhere but you het so much more In this. I would never be without this anymore.
