Magnesium is nature's muscle relaxant — it regulates calcium entry into muscle cells, controls neuromuscular junction signaling, and is required for muscle relaxation after contraction. Muscle spasm and tension are classic symptoms of magnesium deficiency. Muscle relaxant drugs are frequently prescribed for conditions caused by or worsened by magnesium deficiency, but they don't address the underlying deficit.
Garrison & Breeding (J Nutr Environ Med, 2003) — magnesium supplementation reduces muscle cramps significantly. Sontia & Touyz (Arch Biochem Biophys, 2007) — magnesium is the physiological calcium channel blocker for muscle tissue.
Continued muscle spasm despite medication, muscle cramps, restless leg syndrome, tension headache
Magnesium glycinate 400mg daily — take at bedtime for sleep and muscle benefits. This addresses the root cause many muscle relaxant prescriptions are masking.

Vitamin D receptors are expressed on skeletal muscle cells. D3 deficiency causes myalgia (muscle pain) and weakness that is clinically indistinguishable from other causes of muscle pain. Many patients prescribed muscle relaxants are simply Vitamin D deficient. Cyclobenzaprine has sedative effects that can mask D3-deficiency fatigue without addressing it.
Plotnikoff & Quigley (Mayo Clin Proc, 2003) — 93% of 150 patients with nonspecific musculoskeletal pain were Vitamin D deficient. Vitamin D supplementation resolved or significantly improved pain in most. This is arguably the most underdiagnosed cause of muscle relaxant prescriptions.
Diffuse muscle pain and weakness (the primary indication for muscle relaxants), bone pain, fatigue
Test 25(OH)D. If deficient (< 30 ng/mL) — supplement 5,000 IU D3 + K2 daily for 3 months, then retest. Resolution of muscle pain may reduce or eliminate need for muscle relaxants.

Cyclobenzaprine is structurally similar to tricyclic antidepressants (amitriptyline) and impairs mitochondrial function through a similar mechanism. CoQ10 is required for mitochondrial energy production in muscle tissue. Impaired CoQ10 contributes to the fatigue and daytime sedation associated with cyclobenzaprine.
Cyclobenzaprine's TCA-like structure suggests similar mitochondrial effects. The drug's prominent fatigue side effect is consistent with CoQ10-related mitochondrial impairment in muscle and brain.
Excessive daytime sedation, fatigue beyond expected drug effect, poor exercise tolerance
Ubiquinol 200mg daily — may reduce cyclobenzaprine-related fatigue.
