For Those From Medical Background

I have been taking supplemental vitamin D3 for approx. three years now. I am wondering if there is an effect on my hypertension which seems to be suggested
in Wikiepedia. I am currently taking 75ug - Wikiepedia advises:
Suggested tolerable upper intake level (UL)[edit]
Based on risk assessment, a safe upper intake level of 250 µg (10,000 IU) per day in healthy adult has been suggested.[10][11]
I am 68years, male and reasonably active, taking amlodipine and Levothyroxine plus a normal dose of some other supplements. I'm 5ft 4ins and 72 kilos (approx) Cholesterol 5.30 (recent test)

Any advice appreciated,Thankyou.....

I am not a biochemist or a pharmacologist so please take my post in that knowledge.

For reasons best know to you, you are taking quite a modest dose of vitamin D3 which no study has shown avh long term deleterious affects.

You are also taking a modest dose of a hypotensive agent which had no interaction, that I know, with D3

Thyroxine of course is a replacement.

I cannot see any problem either now or in the future with your regime.

Have I missed your point?

You already have high blood pressure (amlodopine)? Who has advised the vitamin? If it's not prescribed, you could stop taking it and see if that helps.

Thanks Sqad and Pixie373.
My concern is hypertension and anything which may exacerbate that. There is a section in the link which points out a contributary factor to HT, however that may be so in an overdose situation(which I may have done about a year ago).

I take supplements of my own accord as I am fairly convinced on alternative remedies and preventive supplements as I do have bit of mistrust with GPs and their unhealthy links with drug companies.
Pixie373 -I may give a try to cutting my D3 dose and monitor my BP and see how it goes.....
Thanks again!

well you could say I am a biochemist and pharmacologist

Your dose is one third of the upper recommended dose.
even with outliers and so on, this dose will not show a supramaximal effect.

in plain English the D3 is not connected with your hypertension.

as someone else said - do the experiment - stop taking it and see if your blood pressure comes down. (it wont)

finally you havent told us what your bloor pressure currently is....

Sorry, I forgot BP reading- at my GP I seem to suffer 'white coat syndrome'. That reading was150/85. Using my own machine at home I have had two readings as low as 124/75. Over the las six months, I have lost just under a stone although GP says I have some more to go. - My fitness advisor, on the other hand was full of praise as I didn't have a lot to lose to begin with!

Fortunately, I have also managed to get my GPs approval to come off Simvastatin in recent months.....Now my target is the HT meds....
Thanks for your input everyone! Seasons Greetings!

Happy new year to you xx
