How To Process Your Eggshells For Calcium

[Amazoniac]

interesting. maybe i'll try it now that I'm back in the cold. I have made slow cooked things using 40+ hardness and the calcium seems to have been pulled out of the water into chalk form. It might be that there needs to be a defusing process to pull the egg shell into the water almost like the carbon method in weller water.

May I suggest you to add some water by now? It must be drying..

It makes no sense not to use Jennifer's method of preparing eggshell calcium, they're indigestive when plain.

- Use of Eggshells as a Raw Material for Production of Calcium Preparations

"Obtaining calcium citrate from chicken eggshells had several important goals. Firstly, it was the elimi-nation of microbial contamination of raw materials. The consumption of uncooked eggs and eggshells may result in salmonella enteritidis infection. Studies show that the powder from the eggshells not treated with any bacteria-inactivating agents (such as heat or microwaves) is affected by the increased bacterial growth of raw material (up to 90 × 105 CFU/g) (Has-san 2015). Our own synthesis conducted under a certain temperature (120°C/2 h) effectively inhibited the growth of bacteria and provided adequate steril-ity of the raw material (Ryszka et al. 2007, 2014)."

"Secondly, there was a difference in the availability between calcium citrate and calcium carbonate. Numerous clinical studies have shown that calcium citrate has greater availability than calcium carbonate (Reginster et al. 1993). This is undoubtedly related to the solubility of these salts. Calcium carbonate is soluble practically only in a strongly acidic medium, and calcium citrate is well soluble in neutral and alkaline media, which affects the availability of the latter salt especially in the upper sections of the small intestine (for example in the duodenum, pH = 7). It is also worth mentioning that calcium is absorbed in the alimentary tract in ionised form and a higher dissociation constant of calcium citrate compared to the carbonate may explain the greater bioavailability of the salt (Hansenet al. 1996). An additional advantage of calcium citrate compared to calcium carbonate is that the carbonate is poorly absorbed in patients with stomach hypoacidity. In this disease calcium intake in the form of a citrate salt is recommended (Dolińskaet al. 2008b). Calcium supplements are generally well tolerated and do not have much effect on the absorption of other microelements. Occasionally occurring side-effects such as constipation or flatulence can be removed by replacing preparations containing calcium carbonate with preparations containing calcium citrate (Sanderset al. 2009)."​

You can buy organic egg shell powder for pets in Germany.

Ive tried making it myself - pain in the **** collecting of sufficient amount of shells, messy prepapration, ended up with far smaller amount of powder than expected, and it started smelling bad very soon. Utter waste of time.

That's why it's preferable to use Jennifer's method with pieces (or even whole eggs for convenience) instead of powders.

Guys, do you really feel uneasy about taking plain calcium carbonate powder, such as this?

- Calcium Supplementation in Clinical Practice: A Review of Forms, Doses, and Indications

"A number of factors affect calcium absorption in the gut.[5] Absorption is greatest when the intake of calcium is low and the need is high. Vitamin D levels, an acidic environment in the gut, age, estrogen levels, and dietary fiber intake all play a role in calcium absorption."

"Individuals vary in their ability to absorb calcium. Calcium absorption averaged 35% and ranged from 17% to 58% in a study of 142 healthy pre‐ and perimenopausal women.[9] In this study, calcium absorption was inversely related to total dietary calcium intake, dietary fiber, alcohol intake, and physical activity. Calcium absorption was also positively associated with body mass index, dietary fat intake, and serum 1,25(OH2)D and PTH levels. Women who had the lowest ratio of fat to fiber intake had a 19% lower absorption of calcium when compared with women with the highest ratio of fat to fiber intake. Polymorphisms in VDR were not associated with differences in calcium absorption in this study."

"Calcium is excreted primarily in the urine and feces, with a number of factors thought to increase urinary calcium loss, including intake of caffeine, protein, and sodium, as well as low estrogen levels."

"In a study investigating caffeine intake in 489 women aged 66–77 years, there was a positive association between caffeine intake and bone loss.[10] Bone loss at the spine was greater in women consuming >300 mg of caffeine per day than in women consuming <300 mg/d."

"Protein is necessary for bone formation. Bone is approximately 50% protein by volume. Although increasing dietary protein increases calcium excretion, research has shown this may not necessarily have a negative effect on bone health."

"Calcium supplementation should be considered for individuals who fail to meet the AI for calcium, individuals with osteopenia or osteoporosis, perimenopausal and postmenopausal women, mothers who breastfeed multiple infants, vegans, amenorrheic women, residents of long‐term care facilities, and in individuals who are lactose intolerant or receiving chronic corticosteroid therapy. Supplementation should also be considered for patients with inflammatory bowel or celiac disease. In addition to calcium, vitamin D supplementation should be administered concurrently."

"[..]calcium citrate is more bioavailable than calcium carbonate when given with a meal. The authors suggest that one possible explanation for these findings is a low gastric acid output in some of the study subjects because the absorption of calcium from carbonate requires an acidic environment."

"Calcium citrate should be the supplement of choice in patients with achlorhydria, a condition common in the elderly. In a study dating back to 1985, calcium carbonate was found to be poorly absorbed under fasting conditions in patients with achlorhydria, whereas the absorption of calcium citrate was significantly higher.[31] Of interest, calcium carbonate when taken with breakfast resulted in normal absorption in achlorhydric subjects."

"Calcium citrate should be used in individuals with suspected achlorhydria, inflammatory bowel disease, or absorption disorders." "Additionally, busy individuals who find it difficult to supplement at meals should use calcium citrate, which can be taken with or without food."

"The dosing of calcium supplements can affect both the absorption of calcium and PTH levels. Absorption of calcium is greatest when taken in a dose of 500 mg or less.[36]"

"Timing, dosage, and whether small repetitive doses of calcium are more effective was studied in 30 healthy women ages 21–34.[37] PTH levels and markers of bone formation and resorption were measured. There was not a significant difference in PTH levels whether calcium was taken during the day or at night (9 am vs 9 pm). The size of the dose did have a significant effect of PTH levels: the higher the dose of calcium, the lower the PTH level. Small 200‐mg doses of calcium given 4 times per day also produced lower PTH levels. There was no significant effect on markers of bone formation or resorption in any of the dosing schedules."

"In clinical practice, to obtain optimal clinical outcomes related to calcium supplementation, the dose of calcium should not exceed 500 mg at 1 time. It may be beneficial to supplement in smaller doses 4 times per day to lower PTH levels and decrease bone resorption."

"Calcium supplements are generally well tolerated; however, some patients complain of gastrointestinal symptoms, including constipation, gas, flatulence, and bloating. Although calcium carbonate is the form most often associated with these reported side effects, little information about how to avoid these symptoms is available in the scientific literature.

In clinical practice, calcium from food and supplementation should not exceed the current AI. Calcium citrate should be substituted for calcium carbonate in any patient complaining of constipation, gas, and flatulence or bloating in an attempt to see if symptoms improve. In addition, it is important to determine if lack of fluid or fiber is the cause of constipation. Other causes of gas and bloating, such as lactose or fructose intolerance, food sensitivities, dysbiosis, or celiac disease, should be investigated if symptoms do not improve after changing to calcium citrate."

"Administrations of calcium and levothyroxine should be separated by 4 h; calcium reduces levothyroxine absorption by forming insoluble complexes."

"Tetracyclines should be taken 2 h before or 4‐6 h after calcium supplements; calcium decreases the absorption of tetracycline by forming insoluble complexes."

"Sodium increases urinary calcium excretion."​

I appreciate the encouragement.

What do you mean by the last sentence?

--
I have the impression that the more digestible forms of calcium could go well in gelatin/broth, marmalade or even melt'd chocolate.

your amazing energy, knowledge and willingness to contribute, along with your unusual sense of humor.

Piranha are powerful fish, and they live in the Amazon. So I wonder if you are supplementing your diet with the power and energy of the mighty piranha.
