10 Best Vitamin C Supplements UK 2024 | Boots, Vitabiotics and More

Vitabiotics is one of the UK's leading brands when it comes to vitamins and supplements, winning the Queen's Award for Innovation not once but twice! This effervescent option creates a tasty orange-flavoured drink that's packed with vitamin C and zinc.

In our opinion, this is the best dissolvable option on the market today and makes a convenient addition to your morning routine, whether you're heading to the gym or rushing off to work. It's suitable for both vegetarians and vegans too!

These tablets from Solgar are marketed as the gold standard for supplements, which is reflected in their price. Stored in amber recyclable glass bottles that protect against heat, light and moisture, they offer a more easily digestible form of vitamin C which is pH neutral and non-acidic. 

The supplements also contain citrus bioflavonoids and rosehip extract, as well as rutin and acerola which are additional plant compounds with reported benefits for your immune system. This makes them well worth spending a bit more on!

This offering from Nature's Aid is designed to slowly release vitamin C into your body throughout the day, keeping a sustained level in your system over a 6 hour period. It also contains citrus bioflavonoids to support organ health.

While this is one of the more expensive options on our list, the bottle contains a whopping 180 tablets which should last you approximately 6 months. Nature's Aid is also vegan-friendly and doesn't test any of its products on animals.

This preservative-free option from the UK's favourite vitamin brand is designed to give you constant support throughout the entire day. If you have a busy, hectic lifestyle then this slow-release supplement is a brilliant choice.

It only contains 500 mg of vitamin C, so is a gentle option for anyone who finds 1000 mg too much for their stomach. It also comes with citrus bioflavonoids for added citrus goodness!

We know that getting children to eat healthily can be a difficult challenge, so these chewable tablets are the perfect way to ensure they're getting enough vitamin C. This small bottle has 90 tablets so will likely last your little one around three months.

Sometimes, supplements have a synthetic flavour but these taste great and are easy to chew without turning too chalky. They're definitely worth trying out if you struggle to get your child to eat their fruit and vegetables!

Unsurprisingly, most vitamin C supplements are flavoured with orange — but if you're not keen on citrus then you'll probably find it difficult to take those every day. These blackcurrant-flavoured effervescent tablets are therefore ideal for those who can't stand the taste of oranges!

Some shoppers may prefer to avoid these tablets since they contain artificial colourings and sweeteners, but they're a fantastic purchase if that doesn't bother you and you're looking for some budget-friendly vitamin C.

Since the level of zinc found in vegetables is considerably lower than in meat or dairy, vegans can find that they need to increase their intake via supplements. So, why not get the best of both worlds when shopping for vitamins?

These slow-release vitamin C tablets have added zinc, so you can swiftly boost your immune system with just one pill a day. If you need a higher dose of zinc then you may need to buy that separately but this bottle should be sufficient for most people.

This offering from Boots combines both vitamin C and vitamin D in order to give your immune system a helping hand during those dark winter months when you may not get enough sunlight.

While vitamin D3 is generally more effective than other types of vitamin D, it can only be found in animal products meaning that these tablets are sadly not suitable for vegans. They are vegetarian and lactose-free though.

If you're looking for one simple tablet to take with a glass of water, this 1000 mg option from Protect Wellness will make sure you get a serious dose of vitamin C as well as some rosehip extract!

You only get 30 tablets for £4, so this product isn't the best value for money on the market. Still, if you're after something specifically with rosehip to help with joint issues, then this is worth picking up.

The reason these vitamin C tablets from Tesco sit so low on our list is that they have a lot of additional sweeteners. It's largely personal preference whether you mind the taste of sweeteners, but overall we felt there were better natural options out there.

If you're okay with sweeteners or even like the taste of them, then these chewable tablets are an affordable option that's ideal for those who have difficulty swallowing regular tablets.
