Best supplements for skin: Cheryl reveals she takes THIS in addition to her diet

Cheryl Tweedy has this week revealed the secret to her glowing skin - and it’s a nutritional supplement.

The 34-year-old new mother - who recently returned to The X Factor - disclosed the one product she believed was key to skin health.

“Fish oil capsules, because if you’re eating right it will show in your skin,” she said in an interview with The Mirror.

They contain omega-3 fatty acids which can make a big difference to your complexion, according to experts.

“As well as being necessary for our heart, brain and eye health, omega-3 and omega-6 fatty acids play an essential role in the structure and appearance of the skin,” said Cassandra Barns, a nutritionist.

“They are incorporated into cell membranes in the epidermis - the top layer of the skin - and form a matrix around the cells, helping to maintain the skin’s barrier function and prevent moisture loss.

They are also thought to have a role in the dermis - the lower layer of the skin- by controlling inflammation and minimising collagen damage from UV rays.”

She recommended taking a good quality supplement such as Super Omega 3-6-9 by Quest Nutra Pharma.

The nutrient is also said to help prevent dementia.

A study published in May showed that people with higher omega-3 levels had increased blood flow in the area of the brain associated with memory and learning.

According to the research published in the Journal of Alzheimer's Disease, this could help prevent Alzheimer’s disease.

Omega-3 can also be found in walnuts, chia seeds and oily fish.

The NHS recommend people eat at least two portion of oily fish a week.

Good sources include salmon, mackerel, sardines and tuna.

However, taking a supplement, like Cheryl, can be a more convenient way to top up. 

According to then BDA, the Association of UK Dieticians, there there is no specific recommendation of a dose for omega-3 for the general population.
