Vitamin C is one of the most popular and essential nutrients for maintaining good health. Known for its powerful antioxidant properties and vital roles in immune function and collagen formation, vitamin C supplements are a staple in many households, especially during the cold and flu season.1
While many fruits and vegetables are rich in vitamin C, some people may not get enough from their diet alone, which is where vitamin C supplements come into play. However, with so many available options, choosing the most suitable one can be overwhelming.
Let’s explore ten of the best vitamin C supplements as chosen by H&B customers, highlighting their benefits and unique features.
What are vitamin C supplements?
Vitamin C supplements are an easy way to boost your intake of this essential nutrient, especially if you don’t get enough from your diet. Available in various forms like capsules, gummies, powders and effervescent tablets, they provide a convenient way to support your health.
Vitamin C supplements are particularly helpful for those with busy lifestyles, people who don’t always hit their five-a-day of fruit and vegetables or anyone looking for extra support. For active individuals, vitamin C helps with normal immune system function during and after intense exercise and supports collagen production, which keeps your bones, skin and blood vessels healthy.1,2
While most adults (19 to 64 years old) can meet their daily requirement of around 40mg through food sources such as one medium orange or kiwi, supplements can help fill in the gaps if your diet is lacking. Beyond immune health, vitamin C also plays a role in reducing fatigue, supporting energy levels and serving as an antioxidant to protect your cells from damage.1-3
Our top vitamin C supplements
Vitamin C supplements come in several forms: capsules, effervescent tablets, gummies and powders. Whether you prefer a quick and easy solution to drink or chew there's a vitamin C supplement perfect for your specific needs.
Here’s a closer look at some of the best options as picked by H&B customers, chosen for their standout benefits and added ingredients that could provide additional benefits.
Holland & Barrett’s Timed Release Vitamin C 1000mg tablets gradually release vitamin C throughout the day, providing continuous support for your immune system and overall health.
The slow-release formula ensures a steady supply of vitamin C.3 It’s perfect for busy adults who prefer a once-daily supplement. The slow-release formula may also help minimise gastrointestinal discomfort associated with high doses of vitamin C.3
Zooki Vitamin C 1000mg uses ‘liposomal encapsulation technology’ to enhance vitamin C absorption.4
Liposomes are tiny fat-like particles that protect vitamin C as it travels through your digestive system, ensuring it reaches your bloodstream effectively.5 One study has suggested that this technology may increase the bioavailability of vitamin C, meaning your body may be able to absorb and use more of it (however, more research is needed around this).6
Infused with real fruit extracts and available in citrus orange flavour, Zooki Vitamin C comes in handy 15mL sachets that you can take directly or mix into water, food or smoothies. It’s 100% natural and vegan and uses sustainably sourced ingredients.
Effervescent tablets are perfect if you prefer a drinkable supplement. Holland & Barrett’s Effervescent Vitamin C and Zinc Blackcurrant combines 1000mg of vitamin C with 15mg of zinc, giving your immune system extra support.
Zinc supports the normal function of the immune system, working hand-in-hand with vitamin C to keep you healthy. It also helps protect cells from oxidative stress, complementing vitamin C’s antioxidant properties.2
The blackcurrant flavour adds a delicious twist, making it enjoyable to drink. It’s also available in orange flavour.
For those wanting a higher dose of vitamin C for therapeutic purposes or possible immune support, Holland & Barrett’s Vitamin C 2000mg Powder is ideal. The powder form allows for easy dosage adjustment and simply mixes into water, juice or smoothies, perfect for those who don’t like tablets.
Each serving packs a powerful punch with 2000mg of vitamin C, hitting the upper safe limit for adults. But be cautious – taking too much vitamin C can lead to an upset stomach, including nausea, cramps and diarrhoea.1
Bioglan’s SmartKids Iron VitaGummies with Vitamin C in strawberry flavour provide 12mg of vitamin C and 2.5mg of iron, which are essential for children’s growth, development and normal immune function.
These gummies support normal immune function, iron absorption and healthy skin and gums. Iron also contributes to normal cognitive development in children.2
The strawberry flavour makes these gummies a hit with youngsters, particularly picky eaters or children who have trouble swallowing tablets. The added iron may help prevent deficiencies that lead to fatigue and developmental issues. While the gummies are delicious, they aren’t intended to be treated like sweets. It’s important to follow the product label for proper dosage and keep them out of the reach of children.2,7
Nature’s Way Alive! Women’s Energy Multivitamin Gummies are packed with essential vitamins and minerals for women.
They come in a delicious fruity orange and berry flavour and are packed with vitamins C, B6, B12 and biotin, which support energy metabolism as well as normal hair and skin.
The gummies also contain zinc, which supports fertility, and iodine, which helps with normal thyroid function.2
Nature’s Bounty® Vitamin C Gummies are fully vegan and vegetarian while providing you with 250mg of vitamin C per gummy. These gummies may help to support your immune system and reduce tiredness.
With a delicious orange flavour, Nature’s Bounty® Vitamin C Gummies are a great way to start your day.

The collagen your body produces is essential for maintaining skin elasticity and hydration, while vitamin C enhances collagen synthesis and provides antioxidant protection.2,8
