What Is The Best Form Of Zinc For Psoriasis?
If you ever wondered what was the best form of zinc supplement for psoriasis in terms of absorption just read this post. The soils are depleted, wheat and other crops have little zinc content and phytic acid in bran binds the zinc in the digestive tract thus further lowering the bioavailable zinc.
There is a lot of forms of zinc in supplements – zinc oxide, zinc picolinate, zinc orotate, zinc bisglycinate chelate, zinc gluconate, zinc citrate, zinc L-carnosine, zinc monomethionine – but which one is the best?
In the past I recommended zinc picolinate and gluconate as the best zinc supplements for the price, but in this article you will see that there are even better ones.
Later, in 2017 I wrote a blog post describing the negative effects of zinc deficiency on omega 6 status. In other words a good part of symptoms of zinc deficiency may be caused by inadequate production of omega 6 fatty acids.
Zinc deficiency – growth retardation and hypogonadism
Zinc was found to be an essential nutrient humans can be deficient in in 1961 when a single case report of 21 year old male patient from Iran was published. The patient was diagnosed in 1958 with “dwarfism, hypogonadism, hepatosplenomegaly, rough and dry skin, mental lethargy, geophagia, and iron deficiency anaemia”.
His diet was very low in animal protein and consisted mostly of unleavened bread. He also ate about 0.5 kg of clay every day. The intake of calories and protein (in form of cereals) was adequate and no other deficiency besides the iron deficiency was documented.
During the following 10 months more patients with the similar symptoms visited the hospital.
Growth retardation combined with testicular hypofunction was present in all of them and could not be explained by iron deficiency. No animal studies researching the effects of iron deficiency resulted in symptoms like that.
The only known nutrient causing growth retardation and hypogonadism in animal studies was zinc.
All patients improved on balanced diet which included the animal protein and iron supplementation.
Is zinc supplement necessary?
