We often refer in conversation to a horse or pony having ‘leaky cells’ it is a very common occurrence and can be a primary reason for poor health and poor performance. A common indication is horses that become sensitive to touch, dislike being tacked up and momentarily slow to move forward and after that tiring quickly. It is often accompanied by changes in temperament, getting grumpier and intransigent. For such mal-functions we recommend H29 as we are suspecting that previous polarisation of the cells has or is diminishing. Polarisation is vital with negatively charged Potassium on the inside of the cells and positively charged Sodium on the outside of the cells. The sodium Ions, tiny electrically charged particles feel the magnetic force of potassium though the cell wall that separates them and an electrical wave of energy is produced which results in the flow of nutrients into to the cells and waste out of the cells. Should there not be strict separation the electrical force weakens, nutrients in and out begin to slow and cells prematurely die. Much depends on the health of the cell membrane, stress and change, disease and tocopherol (Vit E) insufficiently or tocopherol ineffectual utilisation can change the porosity of the cell walls weakening them which leads to potassium diffusing out which is described as PKD (Progressive Kalium Depletion) such weakening also allows cell membranes that normally do not readily admit Sodium to no longer act as an effective barrier and sodium starts flowing in (reverse osmosis) and along with sodium, water that waterlogs the cells. Like the pumps on a leaking ship the body extends greater and greater effort to pump out sodium and pump potassium back into the cells prioritising energy supply to the detriment of exertion and other daily functions such as the thyroid gland that helps regulate glucose metabolism. This affects brain function as the only raw material source of energy the brain can use is glucose which has to be oxidised into energy and transported to different parts of the brain, to do this, two minerals are involved Phosphorus and Potassium, with the latter becoming less available especially to a brain under stress that uses a surprisingly large amount of energy, nerve transmission along muscle fibres begin to fail and the critical regulation of acid and alkalinity maintenance in the intestine and blood is affected.
