Best time to take B12

We should not take vitamin B12 very close to bedtime as it may cause insomnia and stimulation. As insomnia can change our moods, we don’t need to take it with food as many believe that taking B12 with food has a more positive effect. As there are many prescribed weight loss pills that have been very effective. The most common are Contrave, Belviq, Phentermine, and Qsymia. According to 2014 review study even as prescribed weight loss pills don’t work as we hope. On an average, they may help us to lose 3-9% of our body weight compared to other pills and even when they are combining with heavyweight loss diet. They are ineffective on their own and not a solution to obesity.


As no magic weight loss cure is suggested by doctors or nutritionist. Those looking for a healthier lifestyle or drop some weight can take a supplement that claims to help lose weight without the lifestyle change, affecting our diet or exercise routine.Vitamin B12 is considered to be the most controversial vitamin of them all and everyone must have enough of it to be healthy. This one vitamin keeps our nervous system, blood and heart health.It fuels our brain, metabolism and even affects our digestion.

We must be aware that it causes a type of anemia that causes low fatigue and overall low energy. As it is found in animal-based food but taking too much of animal protein can cause a significant inflammatory health problem.

We are very lucky as there is no reported risk of higher intake of Vitamin B12 so people who have tried injections to lose weight need not worry but we need to find another answer for long-term health. However, it is our assumption and not the assurance that B12 helps us to lose weight.

As body depends on a variety of vitamins to maintain good health and B12 is the most important for weight control. Vitamin B12 is associated with weight loss and energy boosting. Vitamin B12 plays an important role in body essential functions and, including DNA synthesis. Vitamin B12 also helps the body convert fat and protein into energy.
