Is taking vitamin B12 good for more energy?

Is taking vitamin B12 good for more energy?

No: Vitamin B12 is commonly thought of as a vitamin that improves energy. This is a common misconception. Individuals who have B12 deficiency may become anemic causing tiredness. In these individuals, a B12 shot will improve anemia and thus improve energy. However, non-anemic individuals who receive a B12 injection will not have more energy. ...Read more

Im 21 years old what benefits will taking vitamin B12 pills and fish oil pills do for me? I need more energy. What supplements can I take? Thanks.

Im 21 years old what benefits will taking vitamin B12 pills and fish oil pills do for me? I need more energy. What supplements can I take? Thanks.

Living Life: I know of no physician that would recommend vitamins or supplements to a healthy 21 yo male. Energy comes from being active, getting good sleep unencumbered by alcohol or other drugs. The most accurate advice would also to be living a life that includes very little sugars and regular cardiovascular exercise. One should not assume that pills will give you good health. Good health activities do. ...Read more

Will taking a vitamin B12 complex help with low energy levels?

Will taking a vitamin B12 complex help with low energy levels?

Vitamin B12 : It may help with low energy levels depending on the cause. It is always best to consult a physician to determine the cause of fatigue, low energy, weakness, asthenia, etc. Before self-medicating with vitamin supplements. While vitamin B12 is safe, the cause for feeling tired may have to do with something unrelated to it. ...Read more

Dexpression, lathergic, low level of vitamin b12. And vitamin d deficiency, low level of energy?

Dexpression, lathergic, low level of vitamin b12. And vitamin d deficiency, low level of energy?

And your question?: I'm not sure what you are asking. Yes, vit d deficiency can cause fatigue. It is easy to correct with 5-8000 iu of d3/day. B12 deficiency can be serious too- try 1000 mcg of sublingual b12/day ; if that does not help try injections. See http://bit.Ly/1fnt3ox ; http://bit.Ly/1607tg3 if fatigue persists after correcting then see a good doc to explore the many other possible causes of fatigue. ...Read more

If i buy vitamin B12 supplements and vitamin E supplements. Will it increase my energy and brain power?

If i buy vitamin B12 supplements and vitamin E supplements. Will it increase my energy and brain power?

It depends...: If you are deficient in B12 it will improve energy and can improve brain function. If you are not deficient (levels below 500) it won't help. Vit e is useful as a preventive measure but generally does not give energy or brain power. It would be ideal to consult with a holistic doc to assess the reasons you might lack energy or brain power so you can address the specific causes. ...Read more

How many Monster Energy Drinks (caffeine 166 mg) (taurine 2000 mg) (vitamin B12 590%) (vitamin B6 220%) in a 8 hour period is considered dangerous?

How many Monster Energy Drinks (caffeine 166 mg) (taurine 2000 mg) (vitamin B12 590%) (vitamin B6 220%) in a 8 hour period is considered dangerous?

Two would be tops: for the whole day. Up to 400 milligrams (mg) of caffeine a day appears to be safe for most healthy adults. That's roughly the amount of caffeine in four cups of brewed coffee, 10 cans of cola or two "energy shot" drinks. Although caffeine use may be safe for adults, it's not a good idea for children. ...Read more

I want to add vitamin B12 to my daily regimen but I take Prilosec everyday for gerd. What kind of dose should I take for energy/heart health?

I want to add vitamin B12 to my daily regimen but I take Prilosec everyday for gerd. What kind of dose should I take for energy/heart health?

Vitamin B12: You can take oral vitamin B12 of 1, 000mcg daily. It's not necessarily helpful for energy or heart health, especially if you are not B12 deficient. Prilosec when used for a very long time can cause B12 deficiency. Prilosec should be taken about 30 minutes before meal, and should not be taken together with vitamin B12 as it can decrease the absorption of b12. ...Read more

What are good fortified food sources of vitamin b12 for vegans?

What are good fortified food sources of vitamin b12 for vegans?

Best to supplement: Trace amounts of the cyanocobalamin form of B12 can be found added to cereals, non-dairy milks, meat substitutes and one type of Red Star Yeast. But it may not be enough and our bodies have to convert it to methylcobalamin, which some people do poorly. Why not take 1000 mcg of methylcobalamin. Even doing that a 2 or 3 times a week should insure you get adequate B12. ...Read more

Why B12 shots: What do you aim to achieve with B12 shots. If you are not deficient in B12, there is nothing to be gained by taking the shots.

Which foods increase good cholesterol, vitamin d and vitamin b12?

Which foods increase good cholesterol, vitamin d and vitamin b12?

Not much: Very few. Unsaturated plant fats may help increase HDL a little, as will small amounts of alcohol. Vitamin d is made in your skin in response to light exposure. It is found in many foods, such as dairy products, but most are supplemented. Vitamin B12 is in most animal derived products, but is hard to be deficient in unless you have chronic stomach or intestinal problems or prior GI surgery. ...Read more

The institute of medicine states that because 10 to 30% of older people may be unable to absorb naturally occurring vitamin B12 in foods, it is advisable for those 51 years old and older to consume b12-fortified foods or B12 supplements to meet the recommended intake. ...Read more
