Which?

Iron and B12, along with vitamin D, are the most common nutrient deficiencies in the UK. And failing to take action can affect your health.
In the first episode of a brand new series of our healthy living podcast, our public health nutritionist Shefalee Loth and the founder of CityDietitians Sophie Medlin tell us who is more likely to be suffering nutrient deficincies and they ways we can improve our intake via our diet.
Fatigue, weakness and low energy levels are all signs of iron deficiency, while for low levels of B12, symptons can include tingling or numbness in the hands and feet, poor balance and memory problems.
Plus, for the first time, we've been reviewing iron and B12 supplements to find out which brands are leading the way. Our thorough, independent testing allows us to recommend the products that really work work, and highlight the ones that failed our tests.

VPNs, or virtual private networks, are nothing new. They’re a tool that grants your devices a more secure connection to the internet and have become increasingly popular since the introduction of age-verification on some websites to prevent children from accessing age-inappropriate content.
In this episode of Which? Shorts, we explain what benefits a VPN can provide while you surf the web, and how you can decide how likely you are to benefit from using one.
Plus, we reveal what we did to test some of the most popular VPNs to decide which ones are worthy of our coveted Best Buy.
This episode is read by James Rowe and is based on an article written by Callum Pears, originally published in the April/May 2026 issue of Which? Tech

Today marks a big day for both renters and private landlords as the Renters’ Rights Act comes into force - a bill designed by the government to “secure a fairer future for 11 million private renters in England”. So is it just good news for tenants? Or are there any wins for landlords?
In this episode of Which? Money, our property expert Sam Wilson explains some of the key changes that are being brought in to improve standards for renters, including the abolition of Section 21 no-fault evictions, the introduction of rolling contracts as standard, and rent increases limited to once per year.
Plus, property expert and developer Marta de Sousa discusses whether landlords will leave the market in protest, and whether this could ultimately push rents up by reducing available rental stock.
