Guest guest Posted April 9, 2008 Report Share Posted April 9, 2008 For the below reason is why patients need to be instructed to look for the USP designation on the label. USP tells one that the product has been tested and it is known to dissolve. Many vitamins/minerals/herbals do not dissolve.

Guest guest Posted February 7, 2009 Report Share Posted February 7, 2009 I honestly have no idea at all about this Chuck...that is why I raised the matter of absorption because my sister is one of these people who thinks vitamins and supplements are a waste of money. She believes I can get most of what I need from food and sunshine! She was asking me if I really needed to be taking all these supplements and put the idea in my head that they go were going straight through me. She could be right in my case as I do go for the cheaper ones in larger quantities so they are probably more inferior anyway. As you rightly say the'slow release' coated types are much more expensive and I can ill afford them in all honesty, especially the amount we are recommended to take in Dr P's book and by others on the forum. Anyway, thanks for putting me right..I stand corrected.

Guest guest Posted February 7, 2009 Report Share Posted February 7, 2009 This sounds an excellent tip Gillian. I will most definitely be testing my vitamin and mineral supplements this way. Many thanks Luv - Sheila Some of you may already know this, but she told me that there is an easy way of knowing the quality of a particular vitamin by putting it in a glass of water and waiting for 30 - 60 minutes. If it completely dissolves it is a 'high quality' tablet and its supplementary benefit is obviously being used up by the body. If the tablet is still there in the glass after 4 or 5 hours then it is obviously passed straight through the body without any real benefit.

Guest guest Posted February 7, 2009 Report Share Posted February 7, 2009 HI, On the question of vitamin D which my GP has suggested that I take, and my reply was that I had already tried VITAMIN D with CALCIUM CARBONATE, and that it caused upset stomache and worse bruising. His reply was that some people cannot take vitamin D with calcium carbonate, but I have not seen VITAMIN D on its own. If ones kidneys are not working OK which I feel mine are not, then however much vitamin D one takes will do no good. One has to have a special type of vitamin D which has to be prescribed. There is a lot of research going on with VITAMIN D and the early stages of MS. I cannot drink what I should as it can make me sick, in turn I do not like the hot weather so do not stay out long in the heat. Vitamin D comes mainly from the sun, so in this case one is bound to suffer from VITAMIN D deficiency. They say too that we should not replace our food with vitamins etc, but the land is being depleted of goodness and overfarmed as the population goes up. I also feel that if one is being sick and cannot eat, that this is a natural way that our bodies are getting rid of toxins, and as food is our source of vitamins one should not keep taking vitamin pills. Antibiotics can also make us worse, and this has happened to me, and my GP has said no more antibiotics, and this has left me with an even bigger problem if surgery is needed. Try not to buy a large bottle of vitamins etc as I have had to throw a lot away. Hope some of this is useful and good luck.

Guest guest Posted February 7, 2009 Report Share Posted February 7, 2009 Hi Sheila, I fear I may have alarmed people unecessarily here. Chuck has thrown new light on my concerns (regarding the acidic environment of our digestive system) which may render them invalid. He is right I think because you can't really compare the absorption of a vitamin tablet in all these enzymes against a glass of water! It probably won't hurt to test them though, just out of curiosity. Gillian > > This sounds an excellent tip Gillian. I will most definitely be testing my > vitamin and mineral supplements this way.

For many supplements, she is correct in a sense. Mega doses often just produce nutrient rich urine. Evidently selenium (up to 200 mcg) and D are exceptions, based on recent research.

Guest guest Posted February 8, 2009 Report Share Posted February 8, 2009 Hi Gillian, Just a thought- our warm stomachs contain strong acid so this would act much more strongly on tablets that the cold glass of water, so it this really valid? Also there are other materials than the main ingredient to bind a tablet that are mostly inert that also may not dissolve in cold water and are irrelevant to the working content of a tablet, but are vital to it's construction and coherence in the bottle. Subject: Vitamin absorption Hi all, but she told me that there is an easy way of knowing the quality of a particular vitamin by putting it in a glass of water and waiting for 30 - 60 minutes. If it completely dissolves it is a 'high quality' tablet and its supplementary benefit is obviously being used up by the body.

Hi Gillian, some vitamin tablets such as vitamin C can be sucked or chewed which allows them to be absorbed firstly through the buccal mucosa ( lining of the mouth ! ). This area has many blood vessels and capillaries and only a very thin lining so that vitamins and drugs too can be absorbed quickly and easily and this also prevents stomach acid from destroying them. eg Vit B12 is taken sub lingually so that it can be absorbed properly. Some other tablets have a coating on them. This is usually an 'enteric' coating which protects the tablet from the acidic environment of the stomach, allowing it to then dissolve in the alkaline environment of the gut where it is absorbed. Some vitamins would otherwise be destroyed by the stomach acid. Tablets such as Aspirin are formulated in dispersible and enteric coated versions. The enteric one is designed so that as it only breaks up in the intestine it causes less irritation to the stomach lining, which is quite a common side effect of Aspirin. Ordinary tablets are designed to break up at a low pH (in the acidic stomach) and the enteric coated ones will break up in a high pH (in the intestine). Tablets with these coatings are usually much more expensive unfortunately. I hope this has helped. Take care, Jo Quote Link to comment Share on other sites More sharing options...
Guest guest Posted February 8, 2009 Report Share Posted February 8, 2009 Thanks Jo (and everyone else) for your thoughts about vitamin absorption. It is a very complex business trying to work out just what I really need and whether it is atually doing me any good. I take your point about the Vit C. I do buy the chewable tablets (and also the Zinc) so I know their supplementary benefits are being absorbed quite quickly via the mouth. I have always preferred to take soluble painkillers for this same reason because they work very quickly on the pain this way and like you say, Aspirin tablets are renowned for damaging the lining of the stomach and I don't want to risk that. My husband takes dispersible aspirin everyday for his high blood pressure.

Hi, I know this is a few months old topic now but I have low vitamin D and some kidney impairment (along with hypothyroid and a couple of autoimmune conditions) so I thought I would tell what I know, giving a little background first. Vitamin D is usually found in two forms: D2 and D3. D2, also called ergocalciferol, is the vitamin found in plants and invertebrate animals (like insects and crustacea); D3, also called cholecalciferol, is the vitamin which vertebrate animals, including us humans, synthesise through UV exposure. We then " hydroxylate " the cholecalciferol into calcidriol in the liver, which then becomes calcitriol via the kidneys. Calcidriol is also written as " 25-hydroxyvitamin D3 " , and calcitriol is " 1,25-dihydroxyvitamin D3 " . This last one is the one you need to get blood tests for as it is the active vitamin. The special vitamin D that has to be prescribed for kidney patients is basically a synthetic form of hydroxylated vitamin D3, and it is usually only given to people on dialysis, and is infused through an IV solution. Most people with kidney disease but still a reasonable amount of kidney funtion (say, above 20%, not on dialysis) can take large amounts of pill-form vitamin D3 to correct and avoid deficiency. They should not be with calcium. Unfortunately a lot of the vitamin D still sold and prescribed by doctors is vitamin D2, which is not well absorbed by us mammals at all. You would have a very hard time correcting low vitamin D with D2, kidney disease or not. Also unfortunately the D3 *tablets* (ie compressed white powder) are not very well absorbed either. Vitamin D is a fat-soluble vitamin and needs to be in your digestive tract with some fat to be absorbed into your bloodstream. The best vitamin D3 to take is that in an oil base in a gelcap. I am not sure what is on sale in the UK, but most pharmacies and health food shops here in Australia have vitamin D3 for sale in 1,000IU strength in oil-filled gelcaps. This wasn't quite enough for me so I ordered from a reputable USA online vitamin shop some 5,000IU strength gelcaps and I take two a day and it is bringing up my vitamin D nicely despite my kidneys only having 60% function. You should also take the D3 with a meal with fat in it for best absorbtion. Trying to dissolve the fat-soluble vitamins (A, D, E, K) in water isn't a good test of their quality or potency, as oil and water don't mix. Other vitamins, while water-soluble, won't act the same way in a glass of water as in your stomach. For example B12 needs to attach to a glycoprotein called Intrinsic Factor produced in your stomach, not dissolve in H2O. I hope this was useful for some people! -Amber Quote Link to comment Share on other sites More sharing options...
