Best kept secret
Scientifically proven to encourage the metabolisation of fat during physical activity, ensuring efficient use of energy, and helping improve your tone and definition. It's what's inside that matters.
Acetyl L-Carnitine (2g): One of the most popular non-stimulant fat-loss supplements on the market today. A non-essential amino acid found naturally in the human body, necessary for transporting fat to the body’s power-generating mitochondria for use as energy during physical activity. Without carnitine, we wouldn’t be able to use fat effectively as a source of energy, which could result in the body having to break down muscle instead. The key benefit of the acetyl form of carnitine is that it can cross the blood-brain barrier to improve mood, learning and memory as well.

Great product, doesn't taste brilliant on it's own but it's easy to mix into smoothies and porridge.
I weirdly love the taste of this - it’s very bitter, exactly like a big squeeze of lemon juice in a glass of water. I have it first thing in the morning and it wakens my taste buds. I’m not hugely aware of losing weight or becoming more defined with it but I’ve added it in to my fitness regime and overall I’m seeing differences.
I'm not sure about this one. Although if I'm honest I don't take it daily. I have it with my protein shake which is every second day. I am very slowly getting toned but I think that's simply down to the fact that I'm finally moving after months of not. The taste is quite pungent and in the pack reminds me of salt and vinegar crisps, but hides well in the shake.
Have it first thing in the morning in a glass of cold water !
It's a strong taste but seems to be working :)
Too early to tell if this product is beneficial. Seems good value for money though, and it's easy just to fix up as a quick afternoon boost. It tastes like a salty lemon, but a quick shot is easily done.
Ordered this a few weeks ago and already seeing improvements. Down from 20% body fat to 17% ☺️
