How to interpret Blood tests for mineral levels
Posted , 5 users are following.
I have had multiple blood tests following the initial diagnosis of osteoporosis. These range through , minerals calcium, Mg, Phosphate in the blood, and others measuring minerals, infections etc in urine. From what I understand, mineral levels in the blood (except for iron?) give no indication of levels in the bone, as the body balances the levels in the blood by pulling calcium/phosphorous/Mg etc from bones. If blood levels are outside of the healthy ranges this then indicates a different level of issue in the body. Has anyone got some idea of how this actually works and which minerals it is relevant to? I understand hormones etc in blood do indicate direct effect etc on body.

I am now topping up with a calcium tab,et in the morning and a magnesium in the afternoon. I have vitamin D3 every day as prescribed and watch my diet to hopefully cover everything.

Hi Kathleen. Are you also taking K2 which helps to steer calcium into the bones - so we’re told.

Hi Kathleen, I also did the online calculator for Calcium and was concerned that I had probably only been getting around 500mg/day (recommended 1000mg for me). Even adding a supplement 9 months ago only added another 250mg/day. The issue is that if you don't consume enough Calcium (Mg, Boron etc etc other minerals), your body will leach them from your bones in order to keep blood levels stable, but bones etc are being demineralised to do this. I was not aware of this when I had my blood levels tested 9 months ago. If blood levels for Calcium etc are outside normal ranges the problems are more severe. Vit D3 is a hormone and blood levels test appear to accurately reflect true deficiencies - I assume most hormones blood tests are also a direct reflection of deficiency, but minerals might not be. Iron is used in the blood and there are multiple measures and they give a good indication if you are OK.

A couple of yrs ago the NOS stated that although the Ca RDA is 1000 to 1200mg, most folk would actually manage on 700 mg. The body apparently only utilises around 400 mg a day. Also if you keep your D level in an optimal range you will absorb more of the Ca.
i know folk have different ideas as to what the optimal D range is. My last test was 140 nmol/L which I’m happy with as it seems to help my immune system and I nolonger catch colds and other seasonal infections.
Best wishes

I am in Australia and the packet claims to do so based on clinical trials.
It omits the words, may or might, it is that sure of its claims. It is very popular in Australia.

I think we can take more than 400 mg a day just not in one dose as 400 mg all the body can absorb at one time. That's why bone health specific supplements are taken two or three or even up to four times a day, depending on the product.

My understanding is that in general we can absorb up to 500mg in one go.
Sorry if I didn’t explain what I was trying to say clearly. What I was referring to was the average amount of Ca that the body actually USES, on a daily basis to cover all the major bodily functions that require Ca. The difference between this 400mg and the RDA of 1000 to 1200 mg is probably to ensure that everyone will have sufficient Ca entering and eventually being excreted by the body, to ensure that this minimal amount is available.
The NOS figure of 700mg a day Ca intake was deemed a sufficient, excess to cover most people.
I used to get worried about acidic foods, when I first read about the alkaline diet I was first diagnosed with OP and became I became obsessive about checking my urine pH. It was only after becoming aware of the above information from the NOF, that I realised I was being silly.
Provided you have a steady supply of Ca during the day, particularly from diet, as apposed to taking a high dose supplement, which may be more than you can absorb, you will always have a reasonable influx of Ca in circulation, which is available to act as a pH buffer.
Its only when someone’s Ca intake is markedly reduced, be it absorption problems, or anorexia particularly when pregnant, that the body will leech Ca from the bones as a last resort. Best wishes

Bought and ate natto, not sure what the taste issue with this is, I did not have a problem eating a 45g/1.6 oz pack which should be giving me around 350mg of K2. As it comes in a 4 pack for AUD$3.50, I only need to eat 1-2 packs a week as I also eat some sauerkraut, as its a fat soluble vitamin I understand it does not need to be taken daily. Will not be making my own base lentil, chickpea using a starter at this stage. I don't think soybeans is a healthy food, however I see people say that fermented they are OK?
