Vitamin D

Vitamin D supplements causing constipation?

LIZZEE — Tue, 14 Apr 2009 18:39:26 GMT

I took oil-based vitamin D3 supplements of 1000 to 2000 units a day for three months on the advice of my doctor. My levels never got much higher than their starting place of 25, but I developed upper abdominal bloating and discomfort, burning and tightness around my ribcage, and constipation that was only relieved by laxatives. My doctor didn't think it was the result of the vitamin D, but now that I've been off the supplements for three weeks, I am completely back to normal. I wouldn't be convinced of the correlation myself, except that last week I ran into an old friend who has been going to gastrenterologists with exactly the same symptoms, and the doctors can find no cause. She has been taking 1500 units of D3 a day, and is going to stop the supplements to see if her symptoms improve.

Has anyone else experienced this?

Vit D from the Sun and D3 oral suppliments and the Flu H1N1

urbywan — Tue, 10 Nov 2009 17:14:21 GMT

We are in our 50s run 70 miles a week and have been running for 40+ years. We live in the Piedmont of North Carolina. I am outside everyday and still have a great dark tan even today Nov 10th. In addition I take 2000 units a day of D3 oral pills. Eat a veggie diet, just everything the good doc says to do.

Well guess what got nailed with H1N1 10 days ago and at 53 YO it was as nasty as any flu I ever had. Maybe not as long in duration, but even the wife came down with it 3 days after me. I do come in contact with children weekly as I teach a few days a week in the gym. But again Even with all the vit D all the sun all the exercise all the healthy eating etc. The Virus is all over and its hard not to catch.

I did get a seasonal shot in September but my wife did not. Not sure if that is an issue, but it ruled out seasonal flu when we came down with the nasty cough aches chills fever of 102 and spikes, upset gut and headache. Fatigue now since we are better but woof woof!!

Vitamin D2 vs. D3?

lenben — Tue, 09 Jun 2009 10:42:07 GMT

What is the latest update on D2 versus D3? I have read confklicting reports: about half claim that D3 is superior, one says D2 is toxic, while the other half claim that D2 is just as efgfective in small doses.

I am searching a vegan source of vitamin D but understand D3 is fish based. which D could a vegan take?

D3 and Addisons Disease - a majic bullet?

Tallulah2 — Thu, 05 Nov 2009 00:24:27 GMT

I am amazed at what D3 has been doing for me, but OMG the latest is that it appears to be reversing my Addison's Disease !!!!

In recent months I have decreased my dose of hydrocortisone dramatically. I am no longer having major dips as a result of suffering cold upon cold. The swine flu tried to get me, the worst I had was a sore throat for one day (unbelievable for me). During this time I only increased my hydrocortisone by 10 mgs instead of 100 - which is what usually would have happaned had I contracted flu - maybe even with a period of hospitalization until my levels stabilized.

Not only this but my daily dose of hydrocortisone is down to 20mgs from 30 -35 per day. I am no longer taking fludrocortisone. I have also been able to reduce my thyoxin from 100 mcgs day down to 50!!!! My endocrinologist is truly amazed but has warned me not to take my dosages down any further - but I am zinging with energy. I am seriously starting to feel over medicated!!!!

I truly never expected any of this to start happening.

Getting Vitamin D fron the Mercola Tanning Panel - How Much Exposure?

kea7721 — Thu, 29 Oct 2009 18:46:59 GMT

Hello. I ordered the Sun Renew System a few months ago. The instructions say to use it maximum 10 minutes per side every 48 hours. My question is, am I getting enough exposure to make enough D with only 10 minutes on each side if my skin is dark? I tan easily and I already have a pretty good tan and I know the darker you are the longer you need to tan, so I want to know if I am getting enough tanning time to make vitamin D. How can I tell and how do I gauge the length of time as I continue to tan 2 to 3 times a week. Dr. Mercola never really addresses this in any of his videos. All he keeps saying is 10 minutes. Does everyone, regardless of skin type and time spent tanning, only need 10 minutes per side 2 to 3 times a week? Please help.

Thanks,

Kathy Armstrong

I recently received an email saying to avoid it and use fish liver or activated 7 dehydrocholesterol.

Vitamin D - Spray: Where's the research on the NanoMist technology?

Hanjo — Fri, 23 Oct 2009 12:51:24 GMT

Hello from Germany!

A new Vitamin D product is sold at Mercola.com, promising some great advantages:

"Quite simply, the D3 in Sunshine Mist Vitamin D Spray comes in a form your body can start putting to use immediately.*

In short, you spray this fine-mist formula into your mouth, swallow, and the essential nutrients are delivered to your circulatory system, tissues and cells quickly.*

But wait -- there's even more...

The tiny nanodroplets™ in each spray are designed to release the vitamin D3 in a steady, time-controlled manner, ensuring a longer-term benefit and boosting efficiency even further*.

Needless to say, when you combine the Sunshine Mist Vitamin D Spray time-release mechanism with its rapid absorption, you get one incredible product. A product that, in my opinion, is clearly superior to any vitamin D3 pill, tablet, capsule, gelcap, or liquid on the market today. "

Now my question is: where can I see the studies and clinical trials that show these advantages? For example looking at time sensitve blood levels after VitD supplementation, and comparing it to other VitD supplements such as pills or tablets...

Thanks for you help!

Sunny greetings from Munich,

Hanjo Fritzsche

Vitamin D Alternative to Krill Oil?

katielobster — Wed, 14 Oct 2009 14:08:47 GMT

I was going to purchase krill oil to increase my vitamin D levels, but then I read that people who are allergic to shellfish should not take krill oil. Does anyone know of a good alternative?

Vitamin D and children

Hilly621 — Tue, 26 May 2009 17:57:04 GMT

I am looking into supplementing Vitamin D for myself and my 15-month old son. Would Dr. Mercola's spray vitamin D be ok to give my child? I am also 23-weeks pregnant and would like to make sure this is ok for myself. Thanks!

No Access To Safe Tanning Beds

Mr. Phil — Wed, 07 Oct 2009 13:43:59 GMT

If there are no safe tanning bed locations in my area could I go to a tanning salon with conventional tanning beds and wear some sort of EMF protection like a Q-Link pendant? If not, why do you nto recommend this? Thank you.

vitamin D 25 hydroxy vs D 1,25 dihydroxy

nwchiro — Sat, 26 Sep 2009 02:41:38 GMT

recent blood work: 25 hydroxy is 32 (up from 27) however, D1, 25 dihydroxy (not a clue why this test was even run) is above normal at 59. Primary doc says it tells him the form of supplementation i am using to incr. D3 levels is being converted and he's not concerned about the above normal 1-25 dihydroxy. naturopathic doc says 1-25 dihydroxy is not a test to evaluate D3 levels and no explanation of the other. D 1-25 dihydroxy is a marker for lymphoma, sarcoidosis and TB. what's going on ?

Jesse Ed — Wed, 28 May 2008 04:48:05 GMT

Hello, I had a question about vitamin D supplementation.

How much vitamin D do you recommend someone take on a day when they get very little to no sunlight?

And is there a preferred form of oral vitamin D, such as a certain brand or type that is recommended?

Thanks for your help.

Testing Vitamin D levels

ALL4BALANCE — Tue, 22 Sep 2009 19:15:09 GMT

I have a 9 month old son who is still primarily on breast milk and I want to make sure his Vit D levels are sufficient. When and how are levels tested in infants? I had my levels tested in June and they were 110 (it was done by labcorp). So I stopped taking my vit D supplement as I figured with summer I would be getting plenty from the sun and my levels were already too high. How long does it take for the levels to change? When should I recheck my levels? Thank you for any info in this area of health and wellness.

How to test for vitamin D levels?

sheryl29 — Tue, 01 Sep 2009 20:37:13 GMT

I've read on this site that our levels for vitamin D should be done by a specific lab. How is it possible to get a test from this lab? I had one test done at my regular physician's office. It was low, and I've been supplementing. Now that it's time to have it re-checked, this doc believes that to be unnecessary and won't order the test. How can I find a doc who will order a test from labcorp - or is it possible to order one myself online?

Thanks.

Is it possible to overdose on vitamin d from the mercola lightbulbs????

wallace brown — Thu, 31 Jul 2008 20:39:30 GMT

I get plenty of sunlight already when i exercise outside. I read about the mercola light bulbs and benefits and i ordered them. Today i recieved them and I use it in my room all day long. Is it possible to overdose on these light bulbs??? i've heard they offer all the benefits of the sun including vitamin d production. In that case, lets say for example i stay in my room all day with the light on, will I be at risk for excess vitamin d and or excess sun exposure from these sun simulating lights?????

Vitamin D and children

odetojoy — Thu, 26 Mar 2009 05:30:09 GMT

I thoroughly enjoyed "Take Control of Your Health" as well as "Generation XL." I practically devoured them! It is refreshing to hear professionals affirm certain concepts that it seems many of us have known deep down because the fact is that most of us try to listen to our bodies. I especially appreciate the emphasis on the benefits of pure sunshine. My whole life I have always said out loud how much better I feel after being in the sun for awhile. We live in Oregon and so I would like to supplement my four young boys with Vitamin D, especially in the Fall and Winter. After reading Dr. Mercola's recommendations I hurriedly went out to buy the Cod Liver Oil. (lemon flavored mind you!) Boy do I hate to be a "whiner" or "picky" but.... I can't seem to get this stuff down my kids. Would it be appropriate and beneficial if I were to give my boys Dr. Mercola's vitamin D spray instead? If not, any suggestions? Thank you! Allison

Using Blacklights or other 'full spectrum' lights to get the UVB recommended for Vitamin D production

murth001 — Sat, 14 Mar 2009 13:00:22 GMT

I watched your video on Vitamin D production. You recommeded 'safe' tanning beds but I am wondering if the use of the full spectrum lights or blacklights would be as useful.

Vitamine D

Art XXXXX — Sun, 28 Dec 2008 08:11:07 GMT

Been reading your articles on Vitamine D. Have a question, I understand best source is natural sun light, but can we also get it from grow lights or daylight bulbs?
