Supplements are becoming more and more popular with people opting for more natural remedies to treat their ailments.
From arthritis to bloating, research has shown various vitamins and minerals to be just as effective as painkillers and medicines.
Psoriasis is a skin condition which causes skin to become red, flaky, crusty, sore and itchy.
Topical creams and ointments are usually prescribed by doctors to treat the irritable symptoms, but some experts say omega-3 supplements are the answer.
Omega-3 fatty acids are known to boost immune function and reduce inflammation, and research has suggested omega-3 during the first year of life can help protect against a variety of autoimmune disorders.
“Taking omega-3 supplements when autoimmune skin or joint conditions do develop can help relieve the symptoms,” says Holland and Barrett.
“Studies show that high-dose omega-3 supplements can improve the symptoms of redness, thickness, scaling and itching in psoriasis.
“Although little research has looked at the impact of omega-3 fatty acids on psoriatic arthritis, there is good evidence to suggest that omega-3 supplements can improve the symptoms.
“There is also evidence to show omega-3s can improve joint function in other forms of arthritis, offering hope to those who are affected by the condition.”
Eczema is another common skin condition which causes itchy, red, dry and cracked skin which omega-3 can help with.
People with eczema often have significantly lower levels of omega-3 fatty acids, according to the high street health store.
Similar to psoriasis, increasing omega-3 in the diet can help reduce inflammation in the body and significantly improve the symptoms of itchy skin.
Research has found that turmeric, an Ayurvedic (Indian medicine with historic roots) can also lessen eczema symptoms.
The high street health store says: “Several studies have shown a significant improvement in the severity of the effects of skin disease in people with turmeric.
“One 2015 study from Pakistan found that topical formulations containing turmeric eased itchiness, swelling and redness in eczema patients.
“Turmeric can be taken in powder, capsule or tablet forms and even in tea, and of course you can use turmeric as a delicious spice for your food.
“Daily doses of three to four grams have been used in eczema research studies, with positive results.”
As well as helping protect cells against free radicals, Vitamin E can contribute to a healthy immune system.
It adds: “In a study of schoolchildren, those with the highest level of vitamin E-related compounds in their blood experienced 67 per cent less risk of eczema and asthma than children with the lowest levels.”
When it comes to eczema, different treatments work for different sufferers.
For one toddler, who experienced an unbearable bout of eczema, waking up every night scratching herself, a £4 cream her mum found in a high street store, relieved her painful skin.
