Vitamin A: Friend or Foe

Wednesday, 09 April 2014 by

It is well established that high retinoic acid (RA)  levels leads to teratogenic effects both in human and experimental models. Brain abnormalities such as microcephaly, impairment of hindbrain development, mandibular and midfacial underdevelopment, and cleft palate are all implicated.[1],[2] Ingested vitamin A, a fat-soluble vitamin, is delivered to the blood via the lymph system in

In terms of the immune response in humans nutrients have a very important role to play and none more so than vitamin A. a lack of vitamin A results in altered intestinal immune homeostasis. This essential micronutrient supports adaptive immunity through its metabolite, retinoic acid (RA), which is highly enriched in the gastrointestinal tract.

Mega Dose Vit D – Really?

Vitamin D supplementation, and what levels to use are common discussions amongst Nutritional Therapists. I have written a number of commentaries and reviews on this subject over the last couple of years and a recent paper published in the Journal: Joint Bone Spine presents a very interesting take on mega supplementation to restore Vit D status.[1]

Rather than looking at the results as a directive for vigorous upfront Vit D supplementation, as there are obvious considerations that make this as a universal approach very questionable, it remains clinically relevant, and may provide a degree of confidence. What is of greater interest is the rapidly declining levels of serum 25-hydroxy vitamin D (25OHD) after the first month and the differences noted in the weight of the patient.

Michael Ash BSc(Hons) DO, ND, DipION reviews the possibility that strategically selected foods and food concentrates represent a valid therapy for inflammatory illnesses.

There is substantive interest in the potential translation from bench to bedside of simple safe strategies to modify the adverse effects of inflammation. Approaching from a preventative and restorative angle the numbers of papers being published on the role of orally ingested bacteria (probiotics) and in this article – the herb Tumeric (active ingredient of which is curcumin) is presenting increasingly supportive evidence for their reasonable and safe clinical use.

Modern analytical techniques are helping to reveal novel opportunities for inflammation control in the gut and the systemic tissues in new ways that even a few years ago would have been thought of as very alternative!
