Fibro-Response™ is a formula that addresses several bodily systems, such as energy levels, liver detoxification, antioxidant defense, connective tissues, brain/cognition, immune function, and circulation.

In Fibro-Response™, Source Naturals has evaluated the underlying causes of system imbalances in muscular and skeletal metabolism to design a formula that supports alignment and harmony in the body’s interdependent systems and functions.

I've used FibroResponse for over a year and it helps the aching that I have from fibromyalgia tremendously. I had been ordering it from another site for much more, and am delighted that I found it for a good deal less on your site. I've had such good results from the FibroResponse that I decided to try some of the other nutritional supplements you carry. Thanks for making these available at very reasonable prices.

Source Naturals Fibro-Response is a comprehensive formula that soothes muscles and joints by supporting oxygen supply and energy production. Without adequate energy and oxygen, muscles become fatigued, achy, and painful.

Fibro-Response invigorates muscles and joints by:

  • Supporting oxygen supply and energy production
  • Providing powerful antioxidants for healthy joints and connective tissue
  • Assisting healthy liver function for detoxification
  • Supporting the immune system for the restoration mechanism of overworked muscles

Why Use Fibro-Response?

The ingredients in Fibro-Response were carefully selected to influence a range of body systems. Some were included for their combined effects with other ingredients, while some play important roles in more than one body system or symptom. For example:

Muscles and Energy Production
The word “fibro” means fiber or fibrous tissue. Muscle fibers are actually long cells, which individually look like fibers under a microscope. All bundled together, these fibers are our muscles, which need oxygen for optimum strength and function. Muscle fibers are powered by adenosine triphosphate (ATP), a compound popularly referred to as “the energy molecule.” ATP supplies energy for all the body’s myriad of physiological processes.

To provide this chemical energy, the body generates and uses an amazing two to three pounds of ATP every day, through a series of complex chemical reactions. The two main energy production systems in the body, which can be envisioned as “energy factories” in cells are the Krebs cycle and the electron transport chain that require sufficient nutrients to keep the body’s systems running properly.

Joints and Connective Tissue
Healthy connective tissue is essential for proper muscle function. MSM dietary sulfur supports the integrity of connective tissue and joints. Vitamins and minerals support myriad functions of the joints, such as Vitamin D for cell and bone health; Vitamin A for antioxidant function and bone formation; Vitamin C for tissue growth and repair, antioxidants, and at least 300 metabolic functions; zinc for bone formation and immune system strength; manganese for bone growth and formation of cartilage and synovial joint fluid; and copper for bone formation and healthy nerves and joints. Humulex™ hops extract inhibits cyclooxygenase enzyme-2 (COX-2) production. This keeps COX-2 from converting arachidonic acid into prostaglandin E2(PG-E2), a particular type of inflammatory prostaglandin. Inflammation can be minimized on a cellular level.

Liver Support
The liver is one of the largest and most important body organs. Its vital functions include clearing the blood of toxins and producing bile, which aids in fat digestion and carries waste products away from the liver. Liver detoxification is necessary for muscle and joint comfort. Silymarin from milk thistle seeds is an important contributor to the support of healthy liver function. N-acetyl cysteine serves as a precursor to glutathione, a critical selenium-containing antioxidant produced in the liver, which binds to toxins to help remove them from the body. Alpha-lipoic acid and CoQ10 play important roles in supporting liver health because the liver, among all its critical functions, needs to generate an enormous amount of energy and these are components of the body’s energy production process. Fibro-Response also contains a classic Chinese herbal combination traditionally used to harmonize liver “chi” or “energy”.

Antioxidant Support
Antioxidants protect tissues and joints from highly destructive molecules called free radicals. Alpha-lipoic acid complements the antioxidant activity of beta carotene and CoQ10. N-acetyl cysteine, best known for supporting the liver, is also highly valued as an antioxidant. Zinc, selenium and copper support our natural defenses. Together, they provide an armory of powerful antioxidants for joints and connective tissue.

Nervous System Support
Ginkgo biloba is renowned for promoting blood flow to the brain. This is crucial, since brain tissue is very metabolically active, accounting for two percent of our body weight, yet using 15 percent of our total energy supply. GABA is an inhibitory neurotransmitter that may regulate the nervous system and support clear focus. The herb skullcap and vitamin B-6 add further support.
