Psoriasis is a common inflammatory condition of the skin primarily caused by an immune system dysfunction. Chronic inflammation causes increased turnover of skin cells, redness, skin thickening, and plaque formation. Superficial skin cells grow in the lower layers of the skin and slowly rise to the surface. This is a process called turnover that, in most people, takes about a month, but in those with psoriasis takes only a few days.

The causes are both genetic (hereditary) and non-genetic. Non-genetic factors acting upon a person with a genetic predisposition can trigger the disease(1). Such factors are 

  • poor nutrition
  • stress 
  • skin trauma 
  • vitamin deficiencies 
  • infections 
  • certain medications
  • alcohol 
  • smoking

Studies in twins determined that:
  1. Genetic factors predispose to psoriasis.
  2. Genetic factors are not the only cause, since 66% of identical twins do not develop the disease despite having a genetic predisposition (2,3).

Thus in recent years, research on more effective therapies has focused on identifying lifestyle and dietary factors related to the disease (4, 5).

Throughout our clinical experience, we have determined that there are specific lifestyle factors that play a central role in the course of psoriasis. These are nutrition, vitamin D3 deficiency, and stress management.


Most people with psoriasis also develop metabolic syndrome. Metabolic syndrome refers to the difficulty of the body to manage sugar and foods that are easily converted into sugar. Bread, sweets, potatoes, alcohol, fruit juices, and meal frequency are some of the factors that aggravate metabolic syndrome and affect the course of psoriasis and the rate of relapses.

In men, for example, who consume more than two drinks per day, and in women who consume more than one, their treatment ceases to work. Both of the above groups have fewer or no recessive periods from the symptoms of psoriasis (4).

Vitamin D3

As with all autoimmune diseases, psoriasis is associated with deficiency and resistance to vitamin D. 

However, in psoriasis, vitamin D deficiency is even more critical. This is believed to be the main reason why psoriasis improves during summer when sun exposure raises the levels of this vitamin.

Resistance to D3 means that higher than normal levels are needed to achieve the same biological effect produced in non-resistant individuals (8,9).

Several studies have highlighted the importance of vitamin D3 in the treatment of psoriasis(9-14). Administration at high doses of up to 35,000iu over several months has significantly reduced the symptomatology of people with psoriasis(11). (see picture)

Metabolic Factors

It is now known that multiple mechanisms are involved in the genesis of psoriasis. Those mechanisms are influenced by each individual's genetic predisposition, environment, diet, exercise, body deficiencies, and personality. 

Advanced analysis - Metabolomic Analysis® - that detects the metabolic causes of the disease leads to a comprehensive treatment of not just the symptoms but the root causes of psoriasis(10, 15)

Metabolomic Analysis is a Precision Medicine tool that measures tiny molecules that participate in chemical reactions that occur within our cells. It provides accurate data for the personalised treatment and prevention of diseases such as psoriasis and psoriatic arthritis.



Metabolomic Analysis® detects early dysfunctions of the body at the molecular level. It so identifies the different causative factors of psoriasis, which are either inherited (DNA) or environmental (diet, exercise, stress). Metabolomic Analysis accurately measures the organism's deficiencies and malfunctions, helping doctors individualize treatment and prevention approaches. 

According to Harvard Magazine and resent research, metabolomics tests are the most accurate method of assessing a person's health. Metabolomics offers a deep understanding of the mechanisms of human health and disease. 

Our approach restores the body's normal function. The treatment regimen is tailored to the deficiencies, dysfunctions, imbalances, and needs of the individual patient as they are identified through the Metabolomic Analysis® test. It includes, along with any preexisting symptomatic treatment, the administration of specific supplements, vitamins, trace elements, amino acids, and personalised nutrition.

Through our clinical experience, we have observed that the gradual reparation of these factors results in a steady improvement in the vast majority of cases.
