Tash Lankester, a personal trainer at FLEX Chelsea, swears by creatine – a classic bodybuilding supplement – to help her lift more and for longer. “I have been using creatine for almost a year. For me, it is a no-brainer. It is cheap, safe to use, widely researched and has little to no adverse side effects,” she says.

“Creatine is the most scientifically researched supplement,” Lankester claims, “meaning that all of the information we have on it is very reliable. It has been proven to increase lean muscle mass and increase strength and power performance in the gym. Taking it can help you to move faster, lift heavier and effectively progressively overload your lifts – so you are likely to see enhanced results while taking it as opposed to not taking it.”

This is because creatine makes up an important part of the energy production systems inside your cells. If your muscle cells have more energy when you exercise, you may perform better and experience greater improvements over time.

“Creatine is also known to improve brain function in general, so if you are one who struggles to get your head in the game when it comes to your workout, give it a go,” Lankester advises.

Because it’s a naturally occurring substance found in animal cells, it might sound like creatine isn’t something that’s readily available to vegans and veggies but because supplements tend to be synthesized from sarcosine and cyanamide, many creatine supplements are actually vegan-friendly. Still, it’s worth checking labels before buying if you are plant-based.
