Why do my lab results show 'normal' when I still feel exhausted, foggy, and unwell?

Conventional lab tests rely on broad statistical reference ranges designed to detect disease pathology, not optimal cellular health. In functional medicine, Dr. Yvonne Karney evaluates optimal functional ranges, cellular hormone uptake, thyroid antibodies, and metabolic markers to address root-cause imbalances before disease manifests.

What makes Bio-Identical Hormone Replacement Therapy (BHRT) different from synthetic HRT?

Synthetic hormone treatments often use non-human molecular structures that can cause unwanted side effects. Bio-Identical Hormone Replacement Therapy (BHRT) uses hormones that are molecularly identical to what your body naturally produces, matched with cellular detoxification to ensure proper receptor binding.

How does Vitality Renewal approach perimenopause and hormone balance?

Vitality Renewal combines in-depth biomarker testing with individualized Bio-Identical Hormone Replacement Therapy (BHRT), gut and genomic analysis, cellular therapies like Frequency Specific Microcurrent (FSM), and targeted nutritional medicine.

Frequency Specific Microcurrent (FSM)

Frequency Specific Microcurrent

What is Frequency Specific Microcurrent (FSM)?

Frequency Specific Microcurrent (FSM) was developed by Dr. Carolyn McMakin in 1995. Microcurrent devices deliver frequencies and current in millionths of an amp (about 1/1000 the strength of a TENS unit).

In published studies, FSM was shown to increase energy (ATP) production in cells by 500%.
(Just think what that alone can do!). It has been documented to reduce pain and inflammation.
There are 17 peer reviewed published papers documenting the positive effects of FSM in case reports and controlled trials.
Ongoing research is being conducted for additional clinical applications including post-operative recovery, diabetes, organ-system function and more.

About FSM

Microcurrent dates back to the early 1900’s, however, it wasn’t introduced as a battery operated unit until the 1980’s. In the late 1990’s, it was clear that the effects of FSM were reproducible. Since then Dr. McMakin has been training practitioners on using FSM worldwide.

FSM uses the principles of biophysics and the effects of biological resonance and frequencies that seem to change cell signaling and thereby change cell function and even structures, such as scar tissue, to reduce pain and improve function. The frequencies seem to improve healing from physical and emotional injuries, resolve nerve pain, phantom limb pain, muscle, joint, neck and low back pain, fibromyalgia, shingles and inflammatory conditions such as irritable bowel, asthma and chronic fatigue. FSM is not used to treat active infections or cancer or any potentially fatal condition.

At Vitality Renewal, we use FSM as part of our treatment plans, using the philosophy: First, do no harm, with the goal of achieving faster results.

I’m excited to offer this service in my practice. I’d love to help you balance your brain for better health!

Frequently Asked Questions

What is Frequency Specific Microcurrent (FSM) and how does it work?

Frequency Specific Microcurrent (FSM) is a non-invasive electromedical therapy developed by Dr. Carolyn McMakin in 1995. It delivers gentle electrical currents measured in millionths of an amp (microamps)—approximately 1/1,000th the strength of a traditional TENS unit. FSM operates on the principles of biological resonance and biophysics, utilizing targeted frequencies to alter cell signaling, soften scar tissue, diminish inflammation, and relieve acute and chronic pain.
How does FSM therapy affect cellular energy (ATP) and healing?

Published clinical research shows that Frequency Specific Microcurrent increases cellular ATP (adenosine triphosphate) energy production by up to 500%. By boosting cellular energy and restoring normal membrane function, FSM accelerates tissue repair, neutralizes inflammatory cytokines, and facilitates faster recovery from physical injuries, surgeries, and chronic cellular dysfunction.
What conditions can Frequency Specific Microcurrent (FSM) treat?
At Vitality Renewal in Crystal Lake, IL, FSM is integrated into individualized functional medicine treatment protocols to address:

Musculoskeletal Pain: Neck pain, low back pain, joint stiffness, and muscle spasms.

Neurological & Nerve Issues: Nerve pain, shingles (herpes zoster), and phantom limb pain.

Chronic Inflammatory & Systemic Conditions: Fibromyalgia, chronic fatigue syndrome, irritable bowel syndrome (IBS), and asthma.

Tissue & Trauma Recovery: Scar tissue remodeling, myofascial restrictions, and recovery from physical or emotional trauma.
How does FSM differ from a standard TENS unit?
While both therapies use electrical current, they operate at completely different intensities and biological mechanisms:

Current Strength: TENS units use milliamps (1,000 times stronger than microamps), which causes muscle contractions and aims to temporarily numb or block pain signals to the brain.

Cellular Mechanism: FSM uses microamps that mirror the body’s natural electrical currents. Rather than merely masking pain, FSM stimulates cellular healing, enhances protein synthesis, and boosts ATP by 500% to create sustained structural and functional improvements.
Are there any safety restrictions or contraindications for FSM treatment?

FSM is exceptionally safe, non-invasive, and painless, operating under the functional medicine philosophy of “First, do no harm.” However, FSM therapy is not used to treat active malignant cancers, active infections, or any acute, potentially life-threatening medical conditions. A clinical assessment at Vitality Renewal ensures FSM is appropriate and safely customized for each patient’s health profile.
