Glover also warns against pairing too many natural anti-inflammatories, a common supplement for those with joint pain or who are susceptible to regular colds. “Turmeric and curcumin are popular anti-inflammatory supplements that can help prevent soreness and infection,” says Glover.

“But in order for your body to heal and protect itself from illness, it needs some inflammation in the body. You don’t want to take too many supplements that reduce inflammation and stop the body’s natural processes.”

Whether or not over-the-counter supplements can really lower inflammation to a dangerous point hasn’t been proven, but piling on the anti-inflammatories isn’t wise. “I wouldn’t say you would do yourself harm, but it might be counterproductive,” Glover says.

“You can get immunity complexes or relaxing formulas which may contain multiple different compounds, but these are formulated with the inhibitory and complementary doses in mind. The main concern is that it’s very, very hard for an individual on the shop floor to work out what individual supplements work together and what doesn’t,” he adds.

Remember that before taking any supplement it’s always best to talk to your GP. And don’t be nonchalant about your natural supplements – they can be potent too.
