Description

Natural Factors C Extra 500mg - 180 CapsulesVitamin C is a powerful vitamin with infection fighting properties, playing a large role in immune system function. Vitamin C is crucial for the formation of collagen, making this vitamin very important for wound repair, healthy gums, strong bones and teeth, and for the prevention of bruising. As a powerful antioxidant, it protects the aqueous areas of the body (including the blood, intracellular fluid, and interstitial fluid) from free radicals.

Vitamin C is a powerful vitamin with infection-fighting properties, playing a large role in immune system function. Vitamin C is crucial for the formation of collagen, making this vitamin very important for wound repair, healthy gums, strong bones and teeth, and for the prevention of bruising.

As a powerful antioxidant, it protects the aqueous areas of the body (including the blood, intracellular fluid, and interstitial fluid) from free radicals. Because it is a water-soluble vitamin, the body cannot store vitamin C, making regular supplementation vital. The body’s need for vitamin C increases during times of stress because vitamin C participates in the production of vital chemicals, such as those needed for the "fight or flight" response. 

Natural Factors Vitamin C 500 mg also contains 500 mg of citrus bioflavonoids, plus rutin, hesperidin, and rosehips. Bioflavonoids protect, strengthen, maintain and repair collagen, capillaries and connective tissue; and possess powerful anti-inflammatory and antioxidant agents. 

Bioflavonoids have been shown to improve the absorption and therapeutic action of vitamin C and protect vitamin C from oxidation in the body. 

  • Superior antioxidant protection 
  • Bioflavonoids increase the bioavailability of vitamin C 
  • Free from gluten, soy, and GMOs

Good fit, good construction.
Style: CA12289
This filter was a good fit for my Corolla. It appears to be well made. The gasket is resilient and looks like it would seal well, preventing any leakage past the filter. Construction was good, with no holes or gaps in the filter paper itself. Unfortunately, the buyer usually has no way to judge the performance of an air filter, and I'm no exception, so I can't say how effective it is in actually removing dirt from the air going into the engine. But I would buy this filter again.

Fits my 2026 civic sport perfect!
Size: AF151
No issues, fitment is perfect. Great quality for an excellent price. Dealer wanted like $24 for a basic one. Nah I'm good I'll just go on Amazon and get it for $8. Took 30 seconds from start to finish can't get any easier.

Fits well and installs easily.
Size: AF997
This filter looked about the same as the OEM filter. It installed in about a minute. The quality appeared to be fine. It was protected in a cardboard box. It fit my 2014 Subaru Outback perfectly. I just installed it an hour ago so I don’t have any long term observations about longevity or effectiveness. I can’t see any reason why it would not work as well as the original, it seemed identical.

Great fit and quality
Size: AF113
Not a complicated product, but after going to 2 different auto parts stores and this not being in stock, Amazon to the rescue. Arrived the next day and the quality is definitely on par with “store brand” ones from retailers. Definitely cheaper as well.
