Doctor's Best Collagen Dietary Supplement, Types 1 and 3, 240 Count Details

Doctor's Best Collagen Dietary Supplement, Types 1 and 3, 240 Count The collagen network in bone confers structural strength to bone tissue and prevents bone fragility. Deficient or defective collagen production, as can occur with aging, is a risk factor for fractures and other bone deformities.Type I collagen is also the major protein found in skin connective tissue where it is responsible for providing skin with its tensile strength and resiliency. Type III collagen is found at high levels in cardiovascular tissue and also in newly developing skin. It is essential for the proper development of the cardiovascular system and skin tissue. Types I and III collagen are often found together in the same tissues, as each form complements the structural integrity of the other.Vitamin C is required for the synthesis of collagen and participates at nearly every step of the process. The critical role of vitamin C involves preventing the inactivation of several key enzymes required for collagen biosynthesis. Studies suggest that vitamin C enhances the function of fibroblasts and promotes an increased level of collagen deposition by these cells in human tissue. Vitamin C also functions to promote the strengthening of the collagen matrix and supports an increased level of collagen density in organs and tissues. These effects of vitamin C also suggest that intake levels of this vitamin may be inadequate as we age. As oxidative stress in tissues increases with age, there is an increased requirement for this crucial antioxidant vitamin to promote optimal collagen production. Read more

Dr Heater quartz + ptc infrared portable space heater is the most recent entrant in the field of furniture style infrared heaters. Introduced in 2009, Dr Heater quickly became the best selling infrared heater in its class at Amazon.com.

Much like the EdenPure, it offers standard features such as easy roll casters, remote control, digital display, washable filter, and adjustable thermostat. Safety features such as overheat cut off and tip over protection help to make it child and pet friendly.

But not all infrared heaters are carbon copies of each other

1. The first notable difference between Dr Heater and the others is the components of the heating system. Most infrared heaters incorporate quartz tubes and some type of heat exchanger. But in place of a heat exchanger, Dr Heater substitutes PTC ceramic technology and combines it with quartz bulbs for a dual heating system.

Positive temperature coefficient (PTC) technology is explained like this: "A positive temperature coefficient refers to materials that experience an increase in electrical resistance when their temperature is raised and show a relatively rapid increase with temperature, i.e. a higher coefficient."

In other words, a heater with PTC technology heats up faster than one without.

2. Another major difference as explained to me by a customer service rep at Dr Heater is the use of a blower to distribute the heat rather than just a fan.

Although every blower has a fan of some type, a blower is the complete assembly of a fan including the housing to contain and direct the flow of air. This translates to more direct heat at a faster rate for quick room heat up and quiet operation.

3. The final and most important difference between Dr Heater quartz + ptc infrared portable space heater and the others is price. While everyone else is charging as much as 9 for their 1,500 watt quartz heater, Dr Heater can be purchased for around 0.

Comparison shopping for infrared heaters
When you're comparison shopping infrared heaters make sure you compare apples to apples. Most brands use a numerical designation for each model such as 500, 1000, or 1500. These numbers indicate the wattage of the appliance. If you're not aware of this fact you could easily assume you're getting a great deal on a 1500 watt heater when in fact you would have spent a fortune for a far less powerful 500 watt model.
