Ter bepaling van de vitamin B12 voorziening

De verhoogde detectie van methylmalonzuur in de urine vormt een indirecte marker van een vitamine B12-defici�ntie. Het maakt het mogelijk om conclusies te trekken over het metabool beschikbare vitamine B12. Vitamine B12 fungeert als een co-enzym van methylmalonyl-CoA mutase die in de citroenzuurcyclus methylmalonyl-CoA katalyseert tot succinyl-CoA. Wanneer deze stofwisselingsroute bijv. ten gevolge van een verminderd aanbod van vitamine B12 verstoord is treed een verhoogde excretie van methylmalonzuur op.

De bepaling van methylmalonzuur in de urine is te verkiezen boven de bepaling in het serum: het is eenvoudiger en gevoeliger. De diagnostische waarde van de parameters in serum wordt vaak beperkt doordat vitaminen in het serum gebonden zijn aan bindingseiwitten waardoor de vitamine B12-verzorging op cellulair niveau niet altijd voldoende kan worden bepaald.

Veelvoorkomende oorzaken van een vitamine B12-tekort zijn gastro-intestinale aandoeningen chronische atrofische gastritis en misbruik van alcohol en/of� medicijnen. De gevolgen van het gebrek uiten zich met name in stoornissen in de erytropo�se (megaloblastaire anemie) glossitis gastritis obstipatie en in neurodegeneratieve en psychiatrische symptomen (neuropathie dementie geheugenstoornissen en psychosen).

De uitslagen dienen als basis voor een individuele therapie en moeten met een arts of therapeut worden besproken.

Indicaties:
- bij het vermoeden van een vitamine B12 tekort

Very cool and smooth
Color: Burgundy, Size: Standard (20'' x 26'')
Excellent quality but sold with the expectation of some shrinkage. Once I ran them through a med high dryer the fit was great. They live up to the idea that they are made for hot sleepers

Soft and durable
Color: Olive, Size: King (20'' x 36'')
Second set of these sheets I’ve purchased. One color for fall and winter and another for spring and summer- thick as a sail, soft as silk, cooling as a breeze. I only use bamboo sheets and these ones are better quality than other brands I’ve tried. 10/10

A huge bamboo fan approves!
Color: Dream Blue, Size: Queen (20'' x 30''), Color: Dream Blue, Size: Queen (20'' x 30'')
I switched to bamboo sheets a few years ago and will never go back. I needed more pillow cases and got these - great quality and price AND family owned is a big deal to me. Will definitely order more. Buttery soft and thicker than other brand I’ve been using.

Product is not as described
Color: Charcoal, Size: Queen (20'' x 30'')
Bought 6 of these because I believed the reviews and the product description.. I don’t think these are bamboo because they don’t stay cool. The appearance of them are great.. but that’s the only good quality and I can’t return them because I got rid of the boxes they came in. Won’t be buying anything else from this company

Finally sleeping through the night without waking up drenched
I was dealing with night sweats almost every night. Waking up overheated, flipping my pillow over constantly, just uncomfortable and restless. It was starting to mess with my sleep in a real way. Since switching to this cooling pillowcase (and pairing it with a cooling blanket), it’s been a completely different experience. I’m actually staying cool through the night and not waking up soaked or irritated. The fabric feels cool to the touch right away and doesn’t trap heat like a regular pillowcase. It’s smooth, comfortable, and still feels good after washing. Not stiff or weird like some “cooling” materials can be. Is it magic? No. But does it noticeably reduce overheating and help you sleep better? Absolutely. If you run hot at night or deal with night sweats, this is one of those small upgrades that makes a big difference. I wish I had bought it sooner.
