10 mg

10 mg

180 Sublingual Tablets ( SKU: 9286, NPN: 80036635 )

Benefits

  • Sublingual tablets provide fast and superior melatonin absorption, bypassing liver and gastrointestinal metabolism - pharmacokinetic studies indicate that 30 to 60% of an oral dose of melatonin is metabolized via the liver1 and overall gastrointestinal absorption is variable2,3
  • A singular high-potency sublingual tablet is optimal for those who need higher doses of melatonin (10–20 mg)
  • Derived from non-animal sources
  • Refreshing, natural peppermint flavour
  • Non-habit forming

Feature Summary

Sleep is a vital part of health and many of us are not getting enough. The 2002 Canadian Community Health Survey found about 1 in 7 adults has difficulty falling asleep or staying asleep. Insomnia affects 1 in 3 seniors and is 40% more common in women. Changes in sleeping patterns are largely reflective of our circadian rhythms, which are guided by the pineal hormone, melatonin. Melatonin is known to decline as we age, which accounts for a number of the sleep changes we see throughout life. Additionally, jet lag and shift work can significantly alter circadian rhythms and thus melatonin secretion.4,5,6

Melatonin has shown clinical benefit for inducing sleep or adjusting sleep cycles,7 reducing sleep onset latency and improving perceived quality of sleep, without impairing daytime psychomotor performance.8,9 In fact, supplemental melatonin and bright light therapy are considered standard medical treatment for cases of jet lag, shift work, age-related insomnia, delayed sleep-phase disorder, advanced sleep-phase disorder, and non-24-hour sleep-wake disorder.10 Chronic sleep disturbance is a risk factor for premature aging, diabetes, obesity, cardiovascular disease and certain cancers,11 demonstrating just how important it is to maintain normal melatonin levels to enhance sleep quality.

Medicinal Ingredients

Melatonin (vegetarian source) 10 mg

Non-Medicinal Ingredients

Contraindications

Do not use if you are taking immunosuppressive drugs and/or if you are pregnant or breastfeeding. Do not drive or use machinery for 5 hours after taking melatonin.

Drug Interactions

Melatonin may impair glucose utilization and increase insulin resistance in diabetic patients. However, the clinical significance of this effect on diabetics is unknown.12 Contraceptive drugs can increase endogenous melatonin levels. Theoretically, this may increase the effects and adverse effects of oral melatonin use.13 Fluvoxamine significantly inhibits the elimination of melatonin,14 which some researchers believe could be helpful in the treatment of refractive insomnia.15 However, this interaction may also cause excessive unwanted drowsiness and other adverse effects. Melatonin production and release may be inhibited by beta-blockers16 and non-steroidal anti-inflammatory drugs17.
