In 2015 Dr Kirkland went undercover to investigates clinics offering vitamin infusions and the medical claims being made. Can a shot of vitamins really boost your immune system and improve your health or treat anxiety, depression or hepatitis?

Following the first programme the UK drugs regulator, the MHRA, looked at the industry for more than 6 months and ruled that medical claims about vitamin and mineral infusions would mean these infusions could be classified as medicinal products. The advertising of prescription only medicines is illegal in the UK therefore claims cannot be made that they treat any illness or disease.

After the first programme more than 100 webpages were identified by Dr Kirkland claiming these infusions could treat medical diseases. The drugs regulator wrote to all these sites telling them to remove the claims.

Dr Kirkland was a finalist for best investigative journalism in the Association of British Science Writers in 2016.
