Calcium

Calcium #

Can decrease B2 absorption, competes with Zinc, high levels of calcium decreased tissue levels of Magnesium and exacerbates deficiency.
High levels of calcium decrease absorption of non-heme Iron.
High levels of calcium decrease Phosphorus absorption
Lowers Prolactin, and vice versa. One of the main functions of prolactin is removing calcium from the bone.

Serum levels ~9mg/dL are ideal. (4/12 I got 9.7 (RI 8.7-10.2))

Calcium D-glucarate can help with phase II liver detoxification of Estrogen, but it also ends up ‘detoxing’ other beneficial steroids.

The lower threshold for calcium intake associated with calcium-alkali syndrome may be due to increased Vitamin D intake resulting in enhanced intestinal calcium absorption
Was traditionally associated with elevated serum phosphate, but is now associated with low serum levels - this is a result of the phosphate-binding capacity of calcium carbonate and other calcium-containing supplements.
levels of 1,25-hydroxyVitamin D are generally low in calcium-alkali syndrome because Parathyroid Hormone is suppressed

the peak absorption of calcium occurs at around a 400 mg calcium load and then it levels off. Absorption of calcium may be as high as 60% at very low intake and as low as 20% at a high intake 1200mg minimum per day. 2g-3g is a good idea.
Blackstrap molasses is a good source (200mg/tbsp & 0.5mg manganese & 20% Fe (25% RDI) & 12g sugar). Chickpeas might be a good source too.
Calcium acetate?
Calcium ascorbate?
Natural Calcium - Pure Marine Source?
Stinging nettle infusion
Moringa
Coral calcium, say from Now. Really rich actually.

RP: It’s a very effective, but safe supplement, because the carbonic acid…the carbon dioxide is the form that stimulates bone formation rather than breaking down the bone.
Calcium carbonate is an antacid, neutralizing stomach acidity. In the kidney and urinary tract, this is once again a great problem. Basically what eggshells are made of. Not water soluble at all

- Dissociates in the stomach acid, whereby free calcium can react. Can make you constipated.
- Citrate is safer, since it has an affinity for cations preventing the calcium from complexing as oxalate.
Buy calcium carbonate powder (NOW makes an affordable one), Put 1/3 teaspoon into a cup, Add 1/3 teaspoon potassium/sodium bicarbonate, Add 1 teaspoon glycine, Fill cup with sparkling water, Wait until fizzing stops, Add 1 teaspoon fruit vinegar with mother, Stir, Drink before meals, No digestion issues
CLASH mixes it with ascorbic acid - which creates carbonation and makes the ascorbid acid buffered - into a cup of orange/grape juice.
Excessive consumption (4g+ daily) can cause milk-alkali syndrome.
Increased risk of urinary tract infection associated with the use of calcium supplements

- In conclusion, therefore, our study confirms the superior efficacy of calcium acetate over calcium carbonate in the control of hyperphosphataemia. Very significantly lower mean serum PTH.

Redsun’s prefered form. as carbonate reduces stomach acid.
I think it’s Amazoniac’s favorite as well, even though Ray Peat doesn’t like it.
