Rapid Response:

Vitamin D and C deficiencies Re: NICE guideline on long covid

Dear Editor

It is absurd that NICE wants doctors to "explain to people that it is not known if over-the-counter vitamins and supplements are helpful, harmful or have no effect in the treatment of new or ongoing symptoms of COVID 19".1

Does that mean none of the NICE experts have experience of assessing and correcting the very common deficiencies of essential nutrients especially, in this case, of Vitamins D and C?

Dr David Grimes emphasised in his Blog that 19 world-wide studies have demonstrated that low blood levels of Vitamin D are associated with severe or fatal Covid-19. The latest International studies indicate that a blood level of more than 30ng/ml (75nmol/L) is a level that indicates protection against serious or fatal Covid-19 infection. A target level of 40ng/ml (100nmol/L) would appear to be appropriate, and to achieve this vitamin D in a daily supplement of 4,000 units is effective, perfectly safe, and costs about £12 per year.

Magnesium is needed in the metabolism of Vitamin D and for normal functioning of the myocardium and skeletal muscles. However, low red blood cell levels of magnesium and low white cell zinc levels are also very common but such tests seem to be only available in private laboratories.

Simmons and Smith report the overwhelming evidence of the efficacy of an intravenous vitamin C protocol against coronavirus. They write that in spite of this accumulation of the evidence, the FDA, the CDC, and many respected members of the medical community inexplicably jeopardize their own credibility, apparently to save the irrelevant business model of the pharmaceutical industry.2

It seems that expensive drugs are preferred to cheap essential nutrients
