Considering taking a supplement? Read our guide to the various supplements on the market, plus our top-rated products in each category
Most people can get enough vitamins and minerals from a healthy, balanced diet. However, some people may need to take extra supplements to support the body and its functions. This may be due to age, health conditions, where you live, and more. In these cases, it may be necessary to supplement in order to make sure you’re not at risk of developing any health issues. Being deficient in calcium, for example, is dangerous for our bones, but those who don’t eat dairy, like vegans, may be low.
In general, supplements can be helpful when they enhance the benefits of a well-rounded diet. If you’re considering taking a supplement, read our guide to the various supplements on the market, plus our top-rated products in each category.
Discover how to get the most out of supplements, what supplements should I take?, vitamin health hacks and the best personalised nutrition tests, tried and tested.

Collagen supplements
Collagen is a vital protein building block for skin, bones and muscle. As we age, our bodies produce less collagen, and this can contribute to ageing. Taking a collagen supplement has many benefits. It improves skin elasticity and helps our skin rebuild and repair.
Find out about the best bovine, marine and vegan collagen powders in our collagen supplements guide.
Best collagen supplement
Absolute Collagen Marine Collagen Supplement Drink
Available from Absolute Collagen (£33.99)
Star rating: 5/5
These Absolute Collagen gels come in handy individual sachets, making them easy to take at home, at work or on the go. They contain hydrolysed marine collagen alongside vitamin C. I especially liked the sweet, fruity flavour, which did a great job of masking any fishiness.
After taking a gel every day for three weeks, I feel like I’m starting to see a difference in my skin. It looks more glowy and even in tone.
Available from:
Vitamin D supplements
We need vitamin D for strong bones and teeth, as it helps us absorb calcium from our food. It also has a link with mood and mental health, immune system health and reducing the risk of heart disease.
Find out if you’re getting enough vitamin D and read our guide to the best vitamin D supplements.
Best vitamin D capsules

Vitamin C supplements
Vitamin C is an essential vitamin, but isn’t stored by the body so it needs to be consumed regularly to prevent deficiency. It has many roles, including maintaining healthy skin, blood vessels, bones and cartilage; helping with wound healing; and protecting cells from damage as an antioxidant.
Discover what is vitamin C? and read our review of vitamin C supplements.

Vitamin B12 supplements
Our bodies need vitamin B12 for energy production and proper functioning of our nervous system. It’s found in animal-sourced foods including meat, fish and eggs, so those following a plant-based diet and the elderly – who may not absorb the vitamin as well – may need to supplement.
