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

Just get the Permatex for a better "spray on", both cans I bought required way too much effort in shaking between spraying. I did shake the can well before use.

Best choice! Absolutely necessary for anything above basic stock bass.
Bonded to services well, completely removed panel reverberation in my tacoma. Also really made the doors so much quieter even when closing. Very happy with the result. Used only one set on my 01 tacoma 4 door. Installed inside doors on exterior skin panel, over interior door panel access holes (sealing the door to provide backpressure to door speakers (left drains open)), roof panel, and back wall of cab. Achieved about 70% coverage and am very happy. 2 8in SKAR SVR8 at 1oh on walmart power acustic 2500 (only rated to ~800rms at 2oh, forum showed testing at 1oh worked about 1kw) in 6th order with blow through into cab. With cab gain, im over 130db between ~30 and ~50hz. This was a necessary addition!

Looks good so far, will update once installed
Have not installed this yet, so this is only a first impression review. I bought it to use in the wheel well area on my truck, so I’ll update later once I actually get it on and see if it makes a real difference. So far it looks good out of the box and seems straightforward enough. One thing I’d recommend is making sure you have a sound deadening roller for install, because I would not try putting this on without one. Too early for me to say how well it works for road noise since it is not installed yet, but I wanted to post my initial thoughts for now and will update later.
