Health and Nutrition through the Pandemic

Aside from getting vaccinated as doses are made available, here are some simple but vital health tips we must follow to keep the Covid-19 virus at bay.

Urgent Vitamin/ Mineral Dosing Schedule For Adults

Vitamin D: There is good data that Vitamin D deficiency can worsen complications related to Covid-19. It is recommended that one measures Vitamin D levels before starting supplements. But in my experience, most Indians, especially vegetarians, are deficient in this vitamin, and I suggest any brand like Calcirol or D Rise etc, 60,000 international units (IU) once a week for five weeks and then once a month for five months. Non-vegetarians may check lab levels of Vitamin D first and then start. An excess of this vitamin can be harmful, so follow this dosing schedule strictly.

Vitamin C: Take 500 mg chewable tablet once daily for a month and then once weekly for life.

Vitamin A: Take 25000 IU (one soft gel) daily for one week, then twice weekly for a month, and lastly once weekly for five months.

Vitamin B Complex plus Zinc: Buy any brand such as Becozinc, one capsule daily for a month, then once a week for life. After completing the monthly dose, start Becosule plus—one capsule daily for life. This also adds minerals lost due to RO water usage.

Zinc is a very important mineral for different metabolic pathways and even more important for its role in the immune system and inflammatory responses. In short, it may have a crucial role to play in the body’s defense against respiratory viruses. Zinc deficiency is common — hence the need to supplement it with medicines. Several nutritional sources of Zinc are available and will be highlighted in later presentations, but the need of the hour is a reliable medicine to build it up immediately.


I have chosen an appropriate combined higher dosage for cover and then a maintenance dose for long duration, based on daily recommended allowances based on Recommended Dietary Allowance (RDA). Please do not overdose. Fat-soluble vitamins, ie Vitamins A and D, can accumulate in excess doses and become toxic.
