Gym-goers are being urged to watch what they eat. Many people view dieting and hitting the gym as the epitome of health, but some of the most common supplements used at the gym nationwide might just be wreaking havoc on our digestion.

Chris Dubberley, a gut health expert from Incontinence Shop, is spilling the beans on why certain supplements and diet foods could be more trouble than they're worth.

Protein Bars

Thought to be the perfect snack for gym addicts, newcomers to fitness, or those trying to overhaul their diets and lose weight, a harsh reality has come to light.

Despite being widely embraced, Chris insists that these go-to protein-packed morsels should be avoided during workouts.

The specialist cautioned: "Protein bars are often packed with isolated fibres and sugars that don't digest well and instead ferment in your gut to cause bloating, gas, or diarrhoea. Ingredients like chicory root fibre and maltitol, commonly found in these bars, are notorious for unsettling more sensitive stomachs."

Whey Protein Powder

Chris issued a stark warning about the potential pitfalls of whey protein powder, a favourite among gym buffs for bulking up or slimming down. The expert cautioned that overindulging in this supplement could wreak havoc on your gut's microbial balance.

He said: "Overloading on protein powder can throw off your gut's microbial balance. Some protein powders' added sugars and flavourings might also disturb your blood sugar levels and balance, promoting harmful bacteria growing in your gut.

"While protein is needed for muscle repair, relying too heavily on supplements could lead to a fibre-deficient diet and poor gut health."

Pre-workout Supplements

Meanwhile, Chris raised concerns over the cocktail of ingredients found in pre-workout supplements, popular with athletes and gym enthusiasts for an energy surge. "Artificial sweeteners, preservatives, and caffeine may irritate some people's stomachs. Be sure to listen to your body and adjust accordingly, as everyone's digestive system is different."

On a brighter note, the specialist highlighted creatine as a dietary supplement with real perks, including safeguarding gut cells from damage that could lead to conditions like inflammatory bowel disease.

It's also known to ease discomfort, strengthen gut defences, and block "unwanted substances from entering the bloodstream".
