Eggshell Calcium, Bloodshot Eyes, Bleeding Gums


Apr 20, 2013
Some people who have experimented with eggshell calcium may notice bloodshot eyes or bleeding or sensitive gums. In that context though atypical points to insufficient sodium. Sodium is required for the proper functioning of calcium channels. Two people have e-mailed and asked about this and both times extra salt resolved the problem.

Why would this show up in the eyes? The eyes are sensitive to calcium-sodium fluxes:

Na+-K+ and HCO-3 ATPase activity in retina: dependence on calcium and sodium.

Pharmacological strategies to block rod photoreceptor apoptosis caused by calcium overload: a mechanistic target-site approach to neuroprotection

Calcium Overload Triggers Rod Photoreceptor Apoptotic Cell Death in Chemical-Induced and Inherited Retinal Degenerations

Dr. Peat gives a succinct description of how calcium and sodium interact in his article Salt, energy, metabolic rate, and longevity

Dr. Peat said:
One important function of carbon dioxide is to regulate the movement of positively charged alkali metal ions, such as sodium and calcium. When too much calcium enters a cell it activates many enzymes, prevents muscle and nerve cells from relaxing, and ultimately kills the cell. The constant formation of acidic carbon dioxide in the cell allows the cell to remove calcium, along with the small amount of sodium which is constantly entering the cell.

When there is adequate sodium in the extracellular fluid, the continuous inward movement of sodium ions into the resting cell activates an enzyme, sodium-potassium ATPase, causing ATP to break down into ADP and phosphate, which stimulates the consumption of fuel and oxygen to maintain an adequate level of ATP. Increasing the concentration of sodium increases the energy consumption and carbon dioxide production of the cell. The sodium, by increasing carbon dioxide production, protects against the excitatory, toxic effects of the intracellular calcium.

This is me right now. I just increased my calcium intake over the past 2 weeks. This morning I woke up with zombie bloodshot eyes. And had a dental appt yesterday where the hygenist was very concerned about my inflamed gums. Ate some extra salt hopefully this will take care of it.

I think if you had powdered calcium carbonate making it to the intestine, that might be irritating for the intestine. Serotonin.
