Strontium: I have not found a cell receptor for strontium (Sr) at this time, and to date, there are no |
indications or medical evidence that strontium is essential to human health. |
|
The action of strontium is closely related to that of calcium, although retention of strontium varies inversely with calcium intake. Supplementing larger amounts of strontium increases calcium, but not |
magnesium retention, and it has the potential to lower stomach acid levels, insulin, WBC, germanium, |
fluoride, bismuth, and silicon. These effects should be kept in mind when considering strontium |
supplementation in the treatment of osteoporosis. |
|
In order to help increase bone mineral density (BMD), or for any of the above effects to take place, |
over 1,000 mg of strontium has to be ingested daily (versus a few mg/day obtained through normal |
food intake), and at those amounts, various medical problems may be experienced, which include |
dental caries, rickets, abdominal spasms, nausea, diarrhea, headaches, skin irritation, blood clots, fainting, memory problems, and seizures. As a result, strontium does not appear to serve any unique |
or specific purpose that no other, or better tolerated nutrient could fulfill. |
|
Similarly to iodine pills being somewhat protective in case of a nuclear accident, taking small amounts of the (non-radioactive) trace mineral strontium may offer the same protection when being exposed to the radioactive form of strontium. Some toothpastes that are marketed for "Sensitive Teeth" contain |
strontium chloride as part of their formulation. ¤ |

Dietary Reference Intake (DRI) is a collective term replacing all other reference values such as |
Adequate Intake (AI), Tolerable Upper Intake Level (UL), Estimated Average Requirements (EAR), |
Nutrient Reference Value (NRV), and Recommended Dietary Allowance / Intake (RDA / RDI). |
|
Strontium: DRI (RDA): none Therapeutic Range: 10mg - 2,000mg |
|
Estimated median daily intake of strontium worldwide from food and water is 1mg - 5mg per day. |

General recommendations for nutritional supplementation: To avoid stomach problems and promote |
better tolerance, supplements should always be taken earlier, or in the middle of a larger meal. When |
taken on an empty stomach or after a meal, there is a greater risk of some tablets causing irritation, or eventually erosion of the esophageal sphincter, resulting in Gastroesophageal Reflux Disease (GERD). |
It is also advisable not to lie down immediately after taking any pills. |
When taking a very large daily amount of a single nutrient, it is better to split it up into smaller doses to |
not interfere with the absorption of other nutrients in food, or nutrients supplemented at lower amounts. |
