Well it‘s an association. But a serum retinol of 0.37 mg/L in the COVID-19 group is not even in the deficiency level range. Deficiency is defined as <0.28 mg/L.Retinol Depletion in COVID-19
Abstract
Background and aims: COVID-19 has been a devastating pandemic. There are indications that vitamin A is depleted during infections. Vitamin A is important in development and immune homeostasis. It has been used successfully in measles, RSV and AIDS infections. In this study, we aimed to measure the serum retinol levels in severe COVID-19 patients to assess the importance of vitamin A in the COVID-19 pathogenesis.
Methods: The serum retinol level was measured in two groups of patients: the COVID-19 group, which consisted of 27 severe COVID-19 patients hospitalized in the intensive care unit with respiratory failure, and the control group, which consisted of 23 patients without COVID-19 symptoms.
Results: The mean serum retinol levels were 0.37 mg/L in the COVID-19 group and 0.52 mg/L in the control group. The difference between the serum retinol levels in the two groups was statistically significant. There was no significant difference in retinol levels between different ages and genders within the COVID-19 group. Comorbidity did not affect serum retinol levels.
Conclusion: The serum retinol level was significantly lower in patients with severe COVID-19, and this difference was independent of age or underlying comorbidity. Our data show that retinol and retinoic acid signaling might be important in immunopathogenesis of COVID-19.

Garrett Smith is still not in the deficient range, as shown in the last video where he presented his recent blood work, despite eating a low-vitamin A diet for 3 years.
People with severe COVID-19 are also low in all kinds of vitamins and minerals, that are actually in the deficient range - vitamin D, K2, long-chain omega 3, copper and zinc.
