)would like a safe alternative to alendironic acid ( to maximise absorption of calcium) Thank you

Good one Mr. Chemist... I'm not mentioning the reaction

egg is not bone

It sounds like the filters have clogged with oils or have calcium deposits. You'll need to soak them in a dishwasher detergent (cascade) overnight to cut the oils, rinse well, let dry, then put them in 4-1 water- acid solution to dissolve the calcium. You can also do this part with a watering can somewhere where the acid won't hurt anything.

Yes. There are actually two different forms of calcium supplement: calcium carbonate and calcium citrate. Calcium carbonate is the cheaper one of the two and should be taken with food. Calcium citrate can be taken on an empty stomach and is absorbed well for people who have low levels of stomach acid.

Sodium bicarbonate is not a descaling product. It makes a nice minimally abrasive cleaning agent when mixed as a paste. Sodium ions will exchange with calcium in a water softener when the calcium is dissolved in water. Once the calcium salt (calcium carbonate) forms, it doesn't go back into solution in a neutral or basic environment. A bicarbonate solution will be basic.

Descaling requires an acid. The Tassimo products say "Do not use vinegar" (acetic acid). I suspect they use citric acid in their descaling product. You can try the lemon-flavored Kool-aid (the version packaged in the envelopes that needs a sweetener added when it's a drink). Mix 1 tablespoon of the powder in 1 pint of water. However, you'll need to make more than a pint of the solution since you need 500 ml of liquid per cleaning cycle. (1 pint is ~473 ml.)

I hope this helps.

Fat soluble vitamins
These vitamins are soluble in fats, oils and in fat solvents like alcohol, etc. There are four fat soluble vitamins. They are: Vitamin A, Vitamin D, Vitamin E and Vitamin K.
These vitamins are stored in liver and are not readily excreted in urine and are not absorbed in the body unless fat digestion and absorption proceed normally. Among all the four vitamins only Vitamin K has a specific coenzyme function. Fat soluble vitamins are made up of one or more carbon units and hence they are called Isoprenoid compounds.Their deficiency can cause malabsorptive disease.
Excess intake of these vitamins may cause hyper vitaminoses. Water soluble vitamins
These vitamins are soluble in water. They are again divided into B complex vitamins and non B complex vitamins. B-complex vitamins are - Thiamine (B1), Riboflavine (B2), Niacin (B3), Pyridoxine (B6), Biotin (B7), pantothenic acid, Folic acid and Cyanocobalamine (B12). Vitamin C is the non-B complex vitamin.
These vitamins are not stored in the body (except B12). Hence, they are to be continuously supplied in the diet. The biochemical reactions of these vitamins is through co-enzymes. The common deficiency symptoms of these vitamins are Dermatitis, glossitis, diarrhea, depression, etc.

add dishwasher salt if you live in a hard-water area to prevent calcium build up, and try adding a litre of pure lemon juice to remove the initial crusting, as the calcium is highly alkaline, and the lemon juice, being acidic, neutralises it.
