  • La méthylcobalamine est la forme active de la vitamine B12 pour un bénéfice maximal.
  • Biodisponibilité supérieure à celle de la forme la plus courante, la cyanocobalamine, qui ne se convertit pas en une quantité suffisante de méthylcobalamine pour corriger certaines formes d'anémie, de défauts neurologiques et de vieillissement1.
  • Réduit les niveaux d'homocystéine pour des effets protecteurs sur le système cardiovasculaire
  • Les comprimés sublinguaux permettent une action rapide directement dans la circulation sanguine.

La vitamine B12 est le cofacteur de réactions enzymatiques ayant diverses fonctions physiologiques. Elle est nécessaire à la conversion du méthylmalonyl CoA en succinyl CoA, ainsi qu'à la conversion de l'homocystéine en méthionine par la méthionine synthase, qui est ensuite convertie en S-adénosylméthionine. Une carence en B12 entraîne des déficiences dans ces deux voies, perturbant la fonction neurologique, notamment une mauvaise formation des gaines de myéline, la production de niveaux toxiques d'homocystéine et une production d'énergie inefficace dans toutes les cellules.

Il a été démontré que la méthylcobalamine, la principale forme circulante de B12 et celle qui est transportée dans les tissus périphériques, réduit non seulement l'homocystéine, mais aussi les facteurs inflammatoires et le volume des plaques de l'artère carotide chez les patients ayant subi un accident vasculaire cérébral, ainsi que la douleur et la neuropathie chez les diabétiques. En raison de sa relation avec la production de myéline et la fonction neurologique, une dose élevée de B12 a été utilisée dans diverses maladies neurodégénératives, notamment la maladie de Parkinson, la sclérose latérale amyotrophique et la sclérose en plaques.

Certaines personnes, en particulier celles qui souffrent de malabsorption ou d'un faible apport alimentaire, sont plus exposées à une carence en B12. Les personnes souffrant d'une mauvaise absorption de la B12 dépendent de l'absorption passive, qui est généralement de 1 % de la quantité ingérée. Par conséquent, des doses élevées peuvent être nécessaires pour les personnes ayant des besoins plus importants en B12, comme les personnes âgées et celles souffrant de troubles neurodégénératifs.

Simplicity
Color: Black/Orange
This watch was received exactly as advertised. First off the watch is economical compared to other watches that advertise the same details. I will say that I have gone through numerous Luminox watches only to be disappointed. This watch fits the bill. It does have solar cells which mean it needs to be exposed to light to keep running, not a problem. Three minutes under my surefire light I am golden. The bezel doesn't rotate actually no big deal for me. I have always required that the bezel moves not anymore after having a bezel that rotates I use it next to never. Here's why, the more I rotate the bezel the more the numbers wear off. The strap on the watch with the catches for the strap are perfect. They actually hold the watch strap in place in lieu of like other big name brands that just flop and slide. As far as everyday use goes this watch is my go to. To be honest I have purchased three. This is the only watch I will wear moving forward, yeah the glass my scratch but even the big names like the Luminox I spoke of earlier scratches too.

Favorite watch / solar
Color: Green/Green
I'm partial... I have bought Timex my intire life, they no doubt make the best watches... They take a licking, but keep on ticking is there old commercials.. True.. Great quality, keeps going after many year's... I never bought a solar watch from them prior I have to mention... It should hold up I'm thinking like their battery watches, I hope so. My favorite watch, I own a handful. Watch looks better in person... Downfall, they are trying a new band out of recycled plastic, I don't like it as much as the older bands it's soft, but feels a little strange...

Solar powered
Color: Green/Green
Great watch for us older folks. The hands are large enough to see easily and the fact it is solar powered means batteries do not have to be replaced every year or two.

Nice watch
Color: Green/Green
Very happy with my purchase, rated the purchase with 4 stars due to the band being very stiff, holds doesn't line up to fit wrist properly, don't recommend for seniors to purchase, very difficult to put on.
