Associer la vitamine D à la vitamine K

Pair vitamin D intake with vitamin K to optimize calcium utilization and support bone and cardiovascular health.

The argument is based on a coherent biological mechanism: vitamin D stimulates the production of vitamin K-dependent proteins, such as osteocalcin, which require vitamin K to be activated. This synergy is well-documented for calcium metabolism, helping to direct this mineral toward the bones rather than the arteries. Observational studies and randomized controlled trials (RCT) suggest that combined supplementation could effectively improve bone mineral density and reduce arterial stiffness compared to vitamin D alone (Journal of the American Heart Association, Nutrients). However, optimal dosages for this synergy remain an active subject of research, and direct clinical evidence regarding the reduction of major cardiovascular events in the general population remains limited. The advice is therefore founded on a solid understanding of nutritional physiology rather than mere speculation. It is a prudent preventive approach that values micronutritional balance.

What the graded evidence says

Effect: CVD/cancer prevention in replete adults (VITAL) — no significant reduction
Measured on: VITAL: 25,871 adults

Great for correcting a deficiency; weak as a general preventive if you're already replete.

Others on this

The buzz from a Monster Energy comes almost entirely from its caffeine (and the sugar riding along with it) — the taurine and the B-vitamin megadoses on the can don't add a proven benefit beyond that.

Extreme, prolonged sun deprivation — like months aboard a nuclear submarine — is exactly the scenario where routine vitamin D supplementation makes real sense: several studies on submarine crews (Royal Navy, US Navy) show levels drop markedly within weeks without it.

For women in their 20s: four basics are enough — omega-3, vitamin D3, magnesium glycinate, and a quality probiotic — rather than 15 supplements.

Dr. Gominak's theory — that low vitamin D disrupts the gut microbiome, which then stops making enough B vitamins, which then breaks sleep — comes from a single practitioner who herself acknowledges the mechanism hasn't been confirmed by other research teams: an interesting lead, not (yet) established evidence.
