Cranberries are small, round, red berries, which grow on vine-like plants native to North and South American countries such as USA, Canada and Chile.
They are closely related to other berries including blueberries, bilberries and lingonberries.
Cranberries are also grown in the UK and other European countries.
They are an excellent source of vitamins and minerals and taking a cranberry supplement is a great way to harness these benefits in a quick and easy way.
You might be wondering why you would take a cranberry supplement, rather than just drinking cranberry juice.
Well, you would have to drink a lot of cranberry juice to come close to the concentrated benefits of cranberry supplements.
Cranberry juice is also high in both calories and sugar.
Each 100ml glass of juice contains 45 calories and 12g of sugar. This is three times as many calories and four times as much sugar as the berries themselves.
As well as this, cranberries have a very tart flavour which is not to everyone’s taste and so taking a supplement means you get all the nutrients in a palatable way.
They are not often eaten as berries because of their strong flavour.
Cranberry sauce is a popular condiment, especially as an accompaniment to turkey at Christmas time.
However, this sauce also has a high sugar content, and so while it is great on occasion, it is not the healthiest and should not be eaten every day.
