Natural Factors Vitamin B-12 Methylcobalamin, 1000mcg, 90 Sublingual tablets
Vitamin B12 works with folic acid to control homocysteine levels. Research shows that high levels of homocysteine may dramatically increase the risk of heart disease and stroke. However, many of us may not be absorbing the vitamin B12 as effectively from food as we could and others, such as vegetarians, may develop outright deficiencies in this important vitamin. Studies show that supplemental vitamin B12 can help us in other ways, too.
Many elderly people suffering from neurological impairment find that B12 supplementation greatly improves their cognitive function. Published studies show that vitamin B12 in supplement form is absorbed better by elderly people than vitamin B12 that is bound to food.
Shift workers, too, can benefit from sublingual methylcobalamin. It’s well established that shift workers have more trouble falling asleep and staying asleep. Poor sleep quality is probably why they have greater susceptibility to illnesses.
In a recent study, subjects taking methylcobalamin experience improved sleep quality and increased daytime alertness and concentration, and in some cases they also reported improved mood. Much of the benefit appears to be a result of methylcobalamin’s influence on melatonin secretion and resetting the biological clock. Specifically, methylcobalamin causes a significant decrease in daytime melatonin levels while increasing nighttime levels.
B12 methylcobalamin makes adrenaline from norepinephrine, and melatonin from serotonin. It is crucial for the transcription of DNA, and other entities. To convert harmful homocysteine into the beneficial antioxidant, methionine, a methyl group is required. Methylcobalamin provides it thereby protecting your cardiac system.
