MCHC POWDER is a complex biological calcium salt manufactured under process designed to ensure that the components retain the natural form and physiological proportions. Caltron's MCHC is the only nutritional substance, which is clinically proven to stop bone loss and even restore lost bone density and helps relieve pain accompanying Osteoporosis. Caltron's MCHC Powder is composed of an organic mineral protein; collagen and the inorganic mineral hydroxyapatite together with broad range of trace minerals.

The Microcrystaline structure of Caltron's MCHC Powder, contributes to improved Calcium Absorption as it provides a large surface area from which the mineral in the organic metrics can be released in the intestine.

Molecular Formula of MCHC : 3Ca3(PO4)2 Ca(OH)2
Collagen : Around 30% of bone is composed of organic mineral, which 90-95% is collagen and the rest being non-collageous protein. Collagen is a fibrous protein, which provides bone strength and flexibility.

Hydroxy Apatite : Caltron's MCHC Powder contains more that 50% Hydroxy Apatite. Hydroxy apatite is a combination of Calcium and Phosphorus bound together in a physiological ratio 2:1 in a special matrix structure. X-ray diffraction studies have confirmed the presence of Hydroxy apatite and the micro-crystalline nature of the salt.

Diatom Powder Food Grade

Caltron's Diatomaceous Earth (DE) powder Food Grade addresses a broad spectrum of harmful toxins entering the body including:

Diatom Powder Food Grade:
  • Bacteria
  • Parasities
  • Fungi
  • Protozoa
  • Viruses (including poliovirus)
  • Endotoxins
  • Pesticide and drug residues
  • E-Coli
  • Heavy Metals (including methyl mercury)
  • Proteinaceous toxins produced by some intestinal infections

Many harmful things entering the body have a positive charge. Silica is a semi-conductive mineral which when warmed by body heat becomes negatively charged and gives off electrons. These negatively charged mineral ions and/or individual shells attract bad microbes, free radicals, positively charged waste and other harmful things. Acting as magnets, the negatively charged shells and/or ions attract and absorb positive things that are small enough to go through the holes. Add a sugar molecule and you can trap toxins into the porous food-grade DE particle which is then excreted safely out of the body. Because of the strong charge, each shell can absorb a large number of positively charged substances, whether they be chemical or in the form of bacteria or viruses. They pass on through the stomach and intestine, taking these harmful substances out of the body.

The intake of silica through DE can help you in many ways:
  • Lower High Blood Pressure
  • Lower Cholestrol Level
  • Sore joints feeling better
  • Healthier skin
  • Hair That Grows
  • Teeth and Gums
  • Toughens nails

Hydroxypropyl Methylcellulose Phthalate
HPMC Phthalate (PASS-55)
Caltron has pioneered the technology of manufacturing Hydroxypropyl Methylcellulose Phthalate or HPMCP in India. The material is manufactured under stringent quality standards. Our esteemed clients can avail high quality of Hydroxypropyl Methylcellulose Phthalate (PASS- 55) from us at market competitive prices. These are widely used for coating different types of granules, pellets, tablets and capsules. Moreover, these products are extensively used for binders and micro capsule bases. Moreover, The Hypromellose Phthalate (PASS-55) can be solely used as well as can also be used in combination with other polymers.

Hydroxypropyl Methylcellulose Phthalate (PASS-55) is utilized in enteric film sustained time or a delayed release. In addition to being an excipient for enteric coating of tablets, HPMC-P also possesses (since recent past) biocidal properties, which helps in monitoring and controlling HIV-1 and similar viruses and STDs.
