Dr Amir Khan has issued a warning about taking certain supplements on ITV's Lorraine07:30, 20 May 2026A doctor has issued a warning about supplements, claiming "we don't know exactly how much of everything is in these things". According to the expert, the industry lacks proper regulation, meaning consumers might not be receiving what they expect.‌The body depends on various vitamins and minerals to perform at its best. While most of what we require should derive from consuming a healthy, balanced diet, many individuals take daily supplements to maintain adequate levels.‌Speaking on the Lorraine show on ITV, Doctor Amir Khan offered some cautionary advice about doing so. Initially, he discussed gummy supplements.‌While these may encourage regular consumption, they can contain high levels of sugar. "With gummies - most supplements now come in gummy form, so whether it's vitamin D, magnesium, creatine, they all come in gummy form and that is fine," he said."The thing about supplements is, if you need them, the best way to take them are the ways that you are going to take them regularly.Content cannot be displayed without consent‌"And for gummies, because they taste like sweets, people will take them regularly and they will get their supplementation. So that's all right. "However, he said: "The danger with gummies is they can contain sugar and sweetness, which is a bad thing, really if you have too much." This could also lead people to consume excessive amounts of the supplement.Dr Amir said: "But also because they taste so good people just go back and eat and eat and eat them so you can overdose on gummies." Discussing supplements more broadly, he highlighted that consumers cannot always be certain of what they're consuming.‌He continued: "But the problem with the supplement industry as a whole is that it's not regulated in the same way medicines are. So we don't know exactly how much of everything is in these things and some studies have shown that actually they contain 10 or 12 times more than the recommended dose or some contain very little as well."So there's no regulating that and that's a problem."‌Recommended supplementsWhen it comes to taking supplements, Dr Amir suggested three particular ones: vitamin D, omega-3, and creatine."Vitamin D, I would say," he said.
