Take responsibility for your one precious life – Vitamin D3

Where to start among 6,489 studies and reviews published during the past five years, results from a PubMed search of “dihydroxyvitamin D3.” How about:

“Vitamin D plays a fundamental role in body calcium and phosphorous homeostasis, ensuring proper functioning of the skeletomuscular system. Pleiotropic activities include:

  • Anti-inflammatory and immunomodulatory properties (predominantly downregulation of adaptive and upregulation of innate immunity);
  • An important role in reproduction, pregnancy, placental functions and fetal and child development;
  • Important in neurodevelopment as well as in the functioning of the adult central and peripheral nervous system;
  • Regulation of global metabolic and endocrine homeostasis and the functions of different endocrine organs, as well as in the functioning of the cardiovascular system;
  • Inhibits malignant transformation, tumor progression and has anti-cancer properties on a variety of tumors;
  • Formation of the epidermal barrier and hair cycling; and
  • Ameliorating effects on skin cancer and on proliferative and inflammatory cutaneous diseases.”

Or maybe:

“A study in 6,275 American children and adolescents aged 1–21 years showed that 61% were 25-(OH)D3 insufficient and 9% deficient. In adults, up to 40% are 25-(OH)D3 insufficient and 6% deficient.

Once adequate vitamin D values are reached, to further preserve adequate vitamin D levels in adults, the IOM [Institute of Medicine] recommends a daily dose of 600 IU per day, while the Endocrine Society recommends a dose of 600–2000 IU per day (according to the amount of sunlight the individual is exposed to). There seems to be no additional health benefit in doses higher than 4000 IU/day.

Vitamin D supplementation was protective against acute respiratory tract infections in a 25-(OH)D3 deficient population, especially in those receiving daily or weekly supplementation. However, in children this protective effect could not be reproduced.”

Not to forget Advanced glycation end products alter steroidogenic gene expression by granulosa cells: an effect partially reversible by vitamin D:

“This study suggests that there is a relationship between AGEs (advanced glycation end products) and their receptors (RAGE and sRAGE) with vitamin D. Understanding the interaction between AGEs and vitamin D in ovarian physiology could lead to a more targeted therapy for the treatment of ovarian dysfunction.”


Or similarities to broccoli sprouts’ main effect of Nrf2 signaling pathway activation:

“1,25(OH)2D3 plays a role in delaying aging by upregulating Nrf2, inhibiting oxidative stress and DNA damage, inactivating p53‐p21 and p16‐Rb signaling pathways, and inhibiting cell senescence and SASP.”

Why do we insist on giving ourselves non-communicable diseases?

I recently paid $22.53 after tax for a nearly two-year supply:

A better use of one’s money would be..?

My June 2020 serum 25-OH Vitamin D measurement was 76 on a scale of 0 to 100 from taking a total of 3,400 IU daily. It’s fat-soluble, so I take it along with 1 gram flax oil each time.
