As much as we don't want it admit it, it's probably safe to say the warmer days are behind us. I personally am quite relieved to say that, and not just because I'm looking forward to sleeping without one of the best fans on. 

The end of summer also means it's time to start considering our health before winter arrives. Taking supplements is one way to do this, and whilst I've already shared the best supplements to take during winter, it's now time to think about boosting your immune system in preparation. 

Below, I've summed up the top five supplements that will help you boost your immune system before the colder days arrive. Ranging from Vitamin D capsules to black elderberry formulations, you're bound to find a choice that works for you. 

1. Bio-Kult Boosted

Bio-Kult has previously taken centre stage in our best wellness supplement guide with its Bio-Kult Everyday formulation. However, Bio-Kult Boosted is specifically developed to target your immune system as well as your digestive tract, meaning it's a great option if you're looking for an all-rounder. 

It's four times more powerful than Bio-Kult Everyday, featuring a multi-strain formulation that will keep you feeling well. Bio-Kult also says its ideal for for those on antibiotics, especially if you've found your immune system deteriorating as a result. 

It's recommended to take one capsule daily with food, and is only suitable for adults and children over the age of 12.
