Sunlight and Vitamin D

For the Coimbra patients, were you able to learn of any stories of people who had a negative experience or reaction to the treatment? I am seriously considering the Coimbra approach. I will find a way! But I am trying to gather all the available information right now. There is a lot of good news out there, but before I proceed, I need to know of the potential downsides. Please let me know... I look forward to hearing from you.

There are a lot of people, who are convinced vitamin D in higher dose is toxic. Kidney stones is listed as the most popular side effect. There is no even a single story in facebook groups, where many people takes 60,000IU or biggger dose, with this specific side effect. In reality, the biggest problem with vitamin D high dose is loosing calcium in the bones. But not everyone is experiencing it. I think this side effect is the most unpopular among Coimbra protocol followers. I'm on high dose for 8 months already, I did DEXA and my results are good. I will continue to monitor my BMD closely, as it is potentially the only problem I could face. I think people must find a balance while on high dose. Too much calcium in longer run really can damage kidneys, but too few calcium can cause osteopenia and later on osteoporosis (NOTE: this is my personal opinion). Patients cannot agree as well on this subject, and why some people losses calcium and others doesn't have such problem even on dose higher than 100,000IU. Some people takes more K2 to prevent osteopenia, but my doctor says that K2 is not effective against high vitamin D dose. My doctor says that 30min aerobics/quick walking/other exercises eliminates osteopenia/osteoporosis risk. I will do DEXA in the summer and will know for sure. This side effect shows up pretty quickly from what I have read.

A very interesting and positive book about the author's experience of the high vitamin d protocol. In Englsh.
Multiple Sclerosis and (lots of) Vitamin D,by Ana Claudia Domene. Well written, well researched, and to the point. Also contains a few testimonies from other people who have used the protocol, It is available on Amazon. If you have questions, you can contact Ana through the link in the Facebook groups, (see below).
It includes many links to Facebook groups. The members are people who are patients of the Coimbra Protocol, set up to share their experience with the worls. There is a Portuguese, Spanish and Italian group, and recently a Norwegian group has been opened. If you ak questions in Englih, there is usually someone who will aner you in English. Mot of the groups have about 15,000 members.
There is also an updated list of doctors who have been trained to practise the protocol,

I am start taking 10,000iu a day (with a week of 20,000iu a day). I'm worried that bananas are on the "caution" list. I eat 2 a day (ever day). Is it because of the increased potassium, and the potential increase for kidney's?

I should add, I also have kale daily. Dark leafy greens are so good, and the thought of limiting them really makes diet restrictive.

Says 130g has 9%

but I guess this is 9% for someone who doesn't megadose on vitamin d?

Perhaps bananas (potassium) and kale (calcium) stress kidneys too much, for high dose vitamin-d?

Thanks Blueberry,

Well I ended-up mega-dosing for 2 or 3 days + sunshine. My max was probably 60,000iu in one day.

Back down to 10,000iu for rest of summer.

My readings were:

December (no supplementation) 111 nnmol/L
April (around a month on 1000 iu): 147 nnmol/L

... so i'm probably just above 200 nnmol/L after a bit of mega-dosing, maybe even higher.

I think 15,000iu would be safe, as long as calcium kept low, and 3-4 litres of water daily. But summer is coming, so may be 10,000iu instead. Undecided. Just trying to recover from relapse.

10,000-20,000, iu from just 20-30 mins sunshine, means daily dose of 15,000iu cant really be harmful.

Thank you for your advice and help.

hi again,

I'm just recovering from a relapse too, although my vitamin D was high, it was caused by stress after a car crash.
I get my vitamin D tested 4 times a year, I get it done free once and pay the other 3 times.

You only need to be between 150-225nmol
the mega doses you took are enough for you to be in the 200's or higher

Without a doctor trained in the coimbra approach you shouldn't go over the top.

If you are getting sun this summer you don't need 10 000iu a day, most people I've noticed on here have 5000iu during summer as a maintaining current level.
I even took less than that during his last summer and my level still rose.
So I'd think again about how much you supplement this summer.

I hope others respond as I'm a little worried you are going to get too high.

We don't become anymore protected over 225nmol
