5 supplements to boost your immune system before winter arrives

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.

Vitabiotics has long been considered one of the best supplement brands on the market, and its Ultra Vitamin D 1000IU formulation is a favourite of many. It mostly provides D3, the preferred form of vitamin D, and is perfect for those who have limited exposure to sunlight. 

There are other options if you're looking for a higher dose, but Ultra Vitamin D 1000IU is a perfect daily supplement for keeping on top of your health.

Having grown up taking Sambucol Immuno Forte, I can't recommend it enough.

The formulation also contains Vitamin C and Zinc, both of which are highly regarded for their ability to support the immune system.

It's available in a liquid, capsule or effervescent tablet form, and is suitable for adults (two teaspoons daily) and children (one teaspoon daily) three years and over.
