What are nutritional supplements and why do we need them?

Eating a healthy, balanced diet provides you with the nutrients that you need to support your health.1,2

It’s important to eat a variety of different food groups (e.g., protein, carbs, fruits and vegetables etc.) because the more diverse your diet is, the more beneficial nutrients you get.

At NobleBlu, we know that it’s difficult to achieve a balanced diet all of the time, especially when life gets busy. We’re all for indulging in a sweet treat or enjoying a glass of wine every now and again, and recognise that it’s all about moderation.

But if you don’t eat a balanced diet most of the time, then you may not get enough important nutrients (like vitamins, minerals and trace elements). This could put you at risk of a nutrient deficiency. 3 


What are nutritional supplements?


Nutritional supplements contain high amounts of a food source which has a nutritional or physical effect on the body. 4-6 These ‘food sources’ can include vitamins, minerals, herbal and plant extracts.4-6 Supplements are usually taken as pills, powders, drinks or food.

People choose to take nutritional supplements for lots of reasons. It might be to help correct nutrient deficiencies or to ensure they’re getting all the vitamins and minerals they need to stay healthy and well. 4-7


Do we need nutritional supplements?


Most people can get all the nutrients they need from eating a healthy and balanced diet.8  But in reality, vitamins and mineral shortfalls are common in the UK. These shortfalls are due to lots of factors such as dietary preferences, lifestyle, age and even your geographic location.9

For example, 40% of people in their twenties don’t get enough selenium in their diets, one-third of women are at risk of iron deficiency and more than 1 in 10 young adults don’t get enough vitamin A, magnesium, and iron.10


Vitamin D


Did you know that UK public health guidelines recommend that you take certain nutritional supplements? Vitamin D, which is an important nutrient for healthy bones and immunity, is a great example of this. 3,11  

Vitamin D is sometimes called the ‘sunshine vitamin’. When you’re exposed to sun, your body makes vitamin D naturally. Since there’s not much sunlight in the UK throughout the winter months, vitamin D deficiency is common. So it’s recommended that all healthy adults take a daily vitamin D supplement during autumn and winter months.5,6

Our NobleBlu Immunity supplement is a simple way for you to ensure you get enough vitamin D and to support your health.


Lifestyle Diets


Lifestyle diets such as plant-based, gluten-free, paleo or ketogenic diets are becoming increasingly popular.12,13 These ways of eating often limit or restrict certain foods and/or food groups. If you don’t replace these with suitable alternatives, you might not get enough important vitamins and minerals from your diet.14 If your diet isn’t providing all the nutrients you need, taking a nutritional supplement may help.
