How long does it take your body to absorb b complex vitamins?

How long does it take your body to absorb b complex vitamins?

Only minutes: In most cases b complex will be absorbed quite quickly. One way of verifying this is to see how long it takes between taking a potent b complex and how long it takes to see your urine turn dark yellow & smell like vitamins (caused by b1 & b2). For them to appear in your urine they must be absorbed into your bloodstream and then be filtered by your kidneys, but this can happen within an hour. ...Read more

Vitamins: There is seldom any need to take vitamin supplements in the USA with a balanced diet, but if you do take them follow the directions and do not take more than one each day and it will not hurt you.

Do I take vitamin b complex with magnesium or can I take vitamin B12? For better absorption of magnesium. Currently also take vit D3 thanks

Do I take vitamin b complex with magnesium or can I take vitamin B12? For better absorption of magnesium. Currently also take vit D3 thanks

OK but not 4 absorb.: It is perfectly fine to take b complex/b12 with magnesium but won't enhance absorption. Magnesium is best absorbed on an empty stomach ; b vits can cause stomach upset on empty stomach. B vits, esp. B6, often work in synergy with mag. The best-absorbed forms of mag. Are glycinate ; taurate; citrate is ok too. Epsom salt baths ; topical "magnesium oil" are also good ways to get magnesium into you. ...Read more

Vitamin b complex caused me to break out in acne, after taking it for a year, how long will it take for my skin to improve? I've stopped taking it.

Vitamin b complex caused me to break out in acne, after taking it for a year, how long will it take for my skin to improve? I've stopped taking it.

There's no telling: Trying to figure out what's causing one to have acne is futile. Ignore all "pop" ideas and start using topical benzoyl peroxide 1-2x daily, perhaps 5%. It's not pleasant but it's your best friend. If it doesn't clear you, your physician can add prescription strength Rx. My acne remitted when I was 50; yours will too, someday. Until then, manage it like the serious medical problem that it is. ...Read more

Took Vitamin C_1000mg + B-Complex (500mg of C) for 3 days then tingling began on my body, mostly hand and feet. Stopped intake. How long for relief?

Unlikely causes: Unless you are allergic to some of the OTHER junk that they fill these tablets with or if there were artificial colors, sweeteners, fillers, etc. Then, in my opinion your symptoms are coincidental to taking the pills not caused by them. B-complex is used to treat such symptoms. Vitamin C itself would not in any way damage nerves in 3 days or 3000 days for that matter. Gotta look for other reasons ...Read more

I take B - complex vitamin with my daily men's vitamin. I take it to boost my energy. Can to much B, hurt?

I take B - complex vitamin with my daily men's vitamin. I take it to boost my energy. Can to much B, hurt?

Yes.: Even though B vitamins are water soluble and not stored in our fat like the fat soluble vitamins (A, D, E, K), too much of certain Bs, like B6 and B3 (niacin,) can get you in trouble. Going above 200 mg a day of B6 has the potential to cause numbness and other nerve problems. High doses of Niacin (2000 mg a day) can lead to elevated liver enzymes, jaundice and nausea. ...Read more

Is it okay to take a b complex vitamin in addition to a centrum multi-vitamin?

Is it okay to take a b complex vitamin in addition to a centrum multi-vitamin?

Likely yes; however: There is no harm in taking them together; however, b vitamins are commonly nauseating. Therefore, taking them together may increase the risk of nausea. I would suggest taking them at different times to prevent nausea and to minimize a large peak of b vitamins. Several smaller doses make the vitamin available throughout the day. ...Read more

Can I take a womens multivitamin and a b complex vitamin together?

Can I take a womens multivitamin and a b complex vitamin together?

Depends: The liver needs to phosphorylate the b vitamins so it is not wise to take more than 50 mg of thiamine, riboflavin, or b-6 at one time. If one takes them apart that would not be an issue but some people do not react well to b vitamins that elevated histamine like Folic Acid and b-12. B-12 can feed bacteria which can be a problem for acne, uti's or sinus infections. ...Read more

Should I take vitamin B12 or vitamin b complex?

It depends on: If you have any nutritional deficiencies, reasons for a nutritionally incomplete diet or malabsorption syndromes. Remember if you don't have any defined nutritional deficiencies you are better off getting your micronutrients like the B vitamins from whole foods rather than from supplementation.

How long after starting a b complex vitamin should I start feeling better again?

How long after starting a b complex vitamin should I start feeling better again?

Depends...: B complex vitamin is often taken to help with stress. Magnesium, zinc, other trace minerals and phytonutrients are all also important to recover from stress. I recommend a b complex with 5-mthf because if you have a mutation in the mthfr gene then you would need his form to bypass the mutation. Most important though are lifestyle changes - restful sleep, exercise, diet and prayer/meditation. ...Read more

I'm starting Accutane and was told not to take multivitamins. Is it still ok to take vitamins d, e and b complex?

Yes: The only vitamin you need to avoid while on Accutane is vitamin a. Many multivitamins don't even have pre-formed vitamin a but only a as its precursor, beta-carotene, which is safe to take, so it's safe to take a multivitamin that has only beta carotene and not vitamin a (often labelled as retinol, retinal or retinoic acid or palmitate). ...Read more

Can you take a multi vitamin and a regular vitamin such as vitamin b complex or c?

Can you take a multi vitamin and a regular vitamin such as vitamin b complex or c?

Yes: A multivitamin will seldom supply optimal levels of vitamin c, so I often advise that people take additional vitamin c. Some people will benefit from higher intake of b complex than many multivitamins provide and there is no danger in taking an additional b complex. There is no harm in taking lots of b's except limit b6 to 250 day. Excessive Folic Acid may be harmful- see my comment. ...Read more
