-Based on the best current evidence, it is unwise to consume (through food or supplements) the recommended maximum of calcium. Calcium supplements have been linked to an increased risk for cardiovascular events, vascular calcification, and kidney stones in the Women's Health Initiative [[http://www.nhlbi.nih.gov/whi/references.htm#cad|Calcium/Vitamin D Supplementation Study]]. More recently, a large prospective study from Sweden published in the British Medical Journal(({{pubmed>long:21610048}})) indicates that even when it comes to bone health, more is not better for calcium intake.+Based on the best current evidence, it is unwise to consume (through food or supplements) the recommended maximum of calcium.

 The Institute of Medicine (IOM) released dietary guidelines for calcium early in 2011, and the recommended dietary allowance (RDA) for calcium from a combination of diet plus supplements was set at 1000 mg a day for adult women until age 50 years and 1200 mg a day for women older than 50 years of age. The IOM also set a tolerable upper intake level of about 2000 mg a day for women in these age groups because of some concern about kidney stones and other health risks when calcium intake is very high. The Institute of Medicine (IOM) released dietary guidelines for calcium early in 2011, and the recommended dietary allowance (RDA) for calcium from a combination of diet plus supplements was set at 1000 mg a day for adult women until age 50 years and 1200 mg a day for women older than 50 years of age.

-Several patients and physicians have reported that when patients with low levels of calcium begin to consume the recommended daily intake, they have an increase in symptoms. In the absence of more evidence, it would be difficult to characterize the exact nature of this reaction for certain, however, a 2001 study in mice showed that when mice with low levels of calcium were given supplemental calcium, they had a stronger immune response.(({{pubmed>long:11697802}}))+Several patients and physicians have reported that when patients with low levels of calcium begin to consume the recommended daily intake, they have an increase in symptoms.

 In cases where patients experience a strong immune response after taking calcium, the dosage can be lowered to the level the patient tolerates and it can be increased later, as tolerated.  It may also be worthwhile trying a different calcium source, in case the reaction is a sensitivity to the particular food or supplement. In cases where patients experience a strong immune response after taking calcium, the dosage can be lowered to the level the patient tolerates and it can be increased later, as tolerated.  It may also be worthwhile trying a different calcium source, in case the reaction is a sensitivity to the particular food or supplement.

 <blockquote>Ian Reid and Mark Bolland, researchers at the University of Auckland in New Zealand, said: "The evidence is also becoming steadily stronger that it is not safe, nor is it particularly effective. Therefore, the administration of this micro nutrient should not be encouraged; rather people should be advised to obtain their calcium intake from an appropriately balanced diet.  We should return to seeing calcium as an important component of a balanced diet and not as a low cost panacea to the universal problem of postmenopausal bone loss.</blockquote>     <blockquote>Ian Reid and Mark Bolland, researchers at the University of Auckland in New Zealand, said: "The evidence is also becoming steadily stronger that it is not safe, nor is it particularly effective.

 +==== Warning ====
  
 +Tetra handsets (//used by some emergency services and some private companies//) are hazardous by causing neurophysiological problems to some people. This stems from the loss of calcium from cell membranes
  
 +Put simply, if calcium is lost from cell membranes, the cells can lose their ability to function and can make the cell more  permeable to allergens, toxins and carcinogens.  //Dr Andrew Goldsworthy, Lecturer in Biology at Imperial College, London.//
  
 +==== Calcium in the wrong place ====
  
-{{tag> calcium foods osteoporosis bone_density}}+**//from Wikipedia on calcification//**:- 
 +Intake of excessive vitamin D can cause vitamin D poisoning and excessive intake of calcium from the intestine, when accompanied by a deficiency of vitamin K (perhaps induced by an anticoagulant) can result in calcification of arteries and other soft tissue. 
  
 +Such metastatic soft tissue calcification is mainly in tissues containing "calcium catchers" such as elastic fibres or sour mucopolysaccharides. These tissues especially include the lungs (pumice lung) and the aorta.[5] 
  
 +In a number of breast pathologies, calcium is often deposited at sites of cell death or in association secretions or hyalinized stroma, resulting in pathologic calcification. 
  
 +Calcification can occur in dead or degenerated tissue. 
 +
 +2000  “growth and vitamin D treatment enhance the extent of artery calcification in rats given sufficient doses of Warfarin to inhibit γ-carboxylation of matrix Gla protein, a calcification inhibitor known to be expressed by smooth muscle cells and macrophages in the artery wall.  (({{pmid>long:10669626}})) 
 +
 +
 +1998 "improved warfarin plus vitamin K treatment protocol developed in this study should provide a useful model to investigate the role of MGP in preventing calcification of arteries and heart valves." (({{pmid>long:9743228}})) 
 +
 + 
 +2015 Matrix Gla-protein (MGP) regulates calcification(({{pmid>long:25990696}}))

 +Dr Blaney's 2010 presentation refers to reversal of carotid artery calcification from long term high dose Olmesartan.

Is there an article on managing food sensitivities in the KB? Discussion about possible factors in milk sensitivities and thoughts that use of cheese from goats or sheep could be a possible dietary source of calcium for those affected a while back ... maybe there is a place in this article to mention this.

 In essence, I agree that the jury is still out, but if you feel better avoiding A1 (like by sticking to sheep/goat products and whey products), then that is all one really needs to know -- and one can choose to adjust one diet if one wants while waiting for more evidence. In essence, I agree that the jury is still out, but if you feel better avoiding A1 (like by sticking to sheep/goat products and whey products), then that is all one really needs to know -- and one can choose to adjust one diet if one wants while waiting for more evidence.

 Any dairy products from cows (with the exception of a few rare breeds) that contains protein will contain A1 casein unless it's only whey (e.g. ricotta, whey protein etc). Butter contains trace amounts, cream contains a couple of grams per 100, sour cream is the same as cream (depending on how heavy it was originally). This is pretty exhaustive (plantpoisonsandrottenstuff.info/content/…).Goats and sheep are both fine. There's no hard data on how serious the problems are because they vary person to person, just like all dairy intolerances. – David Moss Feb 16 2010 at 16:24 Any dairy products from cows (with the exception of a few rare breeds) that contains protein will contain A1 casein unless it's only whey (e.g. ricotta, whey protein etc).

 PS  also, the A2 site discusses the role of individual variation in enzymes that break down these proteins -- and enzymes could be affected by bacterial damage to gut -- so if we control the bacteria, perhaps people who couldn't tolerate it would be able to -- so avoiding A1 for some might be a palliative step until they get well. PS  also, the A2 site discusses the role of individual variation in enzymes that break down these proteins -- and enzymes could be affected by bacterial damage to gut -- so if we control the bacteria, perhaps people who couldn't tolerate it would be able to -- so avoiding A1 for some might be a palliative step until they get well.

 I was thinking too, for someone who was having trouble with dairy and wasn't getting enough calcium (and didn't want to take supplements), they might consider sheep or goat milk products.  One wouldn't even need to mention the a1 vs a2 issue, since that is complicated and controversial. I was thinking too, for someone who was having trouble with dairy and wasn't getting enough calcium (and didn't want to take supplements), they might consider sheep or goat milk products.  One wouldn't even need to mention the a1 vs a2 issue, since that is complicated and controversial.
