What’s so Bad about Cortisol?

When you do not get enough rest or are stressed, levels of cortisol are raised.

Lack of sleep and stress put your body on high alert and signal your body to hang on to fat.

This is your body’s way of trying to help you survive because the body perceives stress and lack of sleep as a threat.

This is why deep restful sleep is necessary. Excess cortisol leads to binge eating and encourages your body to store fat.

A good sleep aid and thermogenic fat burner can help you get the sleep you need to get your cortisol at an optimal level.

Some of these nighttime formulas even contain cortisol lowering ingredients to keep your levels in line.

Fat Burning, Cortisol Lowering and Sleep Promoting Ingredients

Sleep Aids

  • Ashwagandha: This ingredient helps both sleep and fat loss. It relieves anxiety and insomnia. Also decreases cortisol which helps you sleep and prevents your body from storing fat. Aids in reducing weight and fat mass.
  • Chamomile – Apigenin: Apigenin is found in high concentrations in Chamomile and is an anxiety reducing and sedating bioflavonoid.
  • L-Theanine: An amino acid that promotes relaxation.
  • Magnesium: Magnesium can be sedating when used as a supplement, especially if one has a deficiency in magnesium, which many people do.
  • Melatonin: A neuro-hormone that helps you fall asleep and regulates sleep cycles. Your body naturally manufactures melatonin in the evening as it grows dark, but the TV and light from electronics can disrupt the creation of this sleep promoting substance.
  • Valerian Root: A sleep promoting herb with a funky odor. May cause morning drowsiness.

Fat Burners

  • EGCG – Green Tea Extract – Camellia sinensis: This is a fat burner works best at doses between 400 and 500 mg of EGCG. EGCG promotes fat reduction and oxidation and slightly lowers insulin, a fat storing hormone. May also block absorption of carbs to an extent.
  • White Kidney Bean Extract: Blocks absorption of carbs.
  • Green Coffee Bean Extract: A fat loss aid and shown to reduce fat mass
  • Cissus quadrangularis: Increases serotonin and acts as a muscle relaxer. Also reduces food intake if used before eating.
  • Coleus Forskohlii: Fat burning agent due to increasing cAMP. May also raise testosterone.
  • Alpha-GPC- Alpha-glycerophosphocholine: Able to increase power output, increase fat oxidation and increase growth hormone.
  • L-Carnitine- ALCAR-Tartrate: Help reduce fat mass, increase insulin sensitivity, increases glucose metabolism which aids in fat loss and may help increase lean muscle.

Recovery Agents

  • B6 – pyridoxine: Necessary for replenishing neurotransmitters dopamine, serotonin and melatonin.
  • 5-HTP: A precursor to serotonin that can cross the blood brain barrier, unlike the precursor tryptophan.
