What is Fasting Days?

Fasting Days is a ketogenic friendly Intermittent Fasting drink mix that helps optimize:

  • energy and healthy glucose metabolism
  • high quality collagen formation
  • hydration and electrolyte balance
  • bone density
  • muscle mass
  • hunger suppression
  • daily calorie management

The Fasting Days Formula

Full spectrum essential amino acids

Drinking essential amino acids (EAA) during your fast stimulates muscle protein synthesis and prevents muscle loss. Each serving of fasting days contains 2,300mg essential amino acids. (L-Lysine, L-Leucine, L-Valine, L-Isoleucine, L-Phenylalanine, L-Threonine, L-Tryptophan, L-Histidine, L-Methionine)
  • EAAs Increase Fat Burning and Support Fat Loss – A large cohort study of 4,429 people found that the individuals with the highest EAA intake had the least body fat, the most muscle, and the best body composition [1].
  • EAAs Support Hormone Balance During Times of Stress – Supplementing with EAAs supports optimal hormone balance, which plays a major role in body composition, endurance and recovery. A human clinical study found that supplementing with 6 grams of EAAs raised testosterone levels and lowered biomarkers of inflammation in comparison to the placebo group [2].
  • EAAs Improve Insulin Health & May Reduce Diabetes Risk – EAA supplementation has been shown to support insulin sensitivity and metabolic rate resulting in improved body composition. For example, a recent weight loss study found that the individuals who had the highest EAA intake had the greatest improvements in insulin sensitivity [3].

  • L-Carnitine (L-carnitine tartrate)
    L-Carnitine is the amino acid responsible for transporting long-chain fatty acids into the mitochondria. Without sufficient amounts of carnitine, fat can’t get into the mitochondria to be burned for fuel. L-Carnitine-Tartrate helps in fat oxidation and improves muscle endurance by preserving muscle glycogen storage and preventing the buildup of lactic acid.

    Next to glutamine, taurine is the second most abundant amino acid found in skeletal muscle. Taurine acts as osmolyte (i.e., it regulates fluid balance). As such, taurine optimizes cellular hydration. Taurine also regulates water and electrolytes in the blood, playing an essential role in preventing muscle cramping. Taurine also has significant antioxidant properties and alters the actions of inhibitory neurotransmitters, which increases brain performance, focus and mental acuity.


    L-Tyrosine is an amino acid that is metabolized to produce neurotransmitters such as dopamine and adrenaline. Increasing levels of these neurotransmitters cause improvements in cognitive function, physical performance, metabolic rate and fat loss.

    L-Theanine is an amino acid naturally found in teas and mushrooms. Theanine supplementation causes the release of the brain neurotransmitter gamma-aminobutyric acid (GABA). GABA boosts mood and mental focus. L-Theanine supplementation is used as a natural remedy to help treat depression since it reduces feelings of anxiety and promotes an overall sense of well-being.

    L-Alpha-Glycerophosphoryl Choline (Alpha GPC)
    L-Alpha-Glycerophosphoryl Choline (Alpha GPC) is a choline-containing phospholipid that enhances cognitive function, increases strength and stimulates the release of growth hormone.

    Studies backing all the way back to the 1990’s have shown that supplementation of Alpha GPC improves memory [4]. Studies have also shown that a single supplemental dosage of Alpha GPC can increase acute growth hormone levels 290% above baseline in healthy adults [5]. The cumulative evidence from animal and human studies support the role of Alpha GPC as a well-tolerated cognitive enhancing compound with additional therapeutic benefits [6].

    L-Glutamine is the most abundant amino acid in human plasma and plays a vital role in the health of the immune system, digestive tract, and muscle cells. Stress, infection, surgery, and trauma can deplete the body’s glutamine reserves, particularly in muscle cells. Supplementing with glutamine will provide a boost to your immune system and reduce stress. For example, a double blind placebo controlled study found that the adults given oral glutamine supplementation caught less infections and had improved ratio of T-helper/T-suppressor cells compared with the placebo (Castell & Newsholme, 1997).

    Prebiotic Fiber sources
    2.2 grams of high quality inulin and methyl cellulose fiber per serving. Inulin is a soluble fibre naturally found in many plants. Research shows that supplemental inulin improves regularity, reduces cholesterol, and promotes weight loss [7]. Inulin acts as prebiotic and feeds good bacteria in the gut. Good bacteria have a number of important functions in our bodies, including [8,9]:

  • Strengthening the immune system
  • Aiding in the absorption of certain minerals
  • Production of B vitamins and Vitamin K
  • Methylcellulose is a non-allergenic and non-fermentable fibre that is created from the cell wall of plants. It is not absorbed by the intestinal tract but instead absorbs water to create a softer stool.

    Citrulline malate

    Citrulline malate is an amino acid made from binding two molecules of L-citrulline to an ester of malic acid (malate). Supplementing with citrulline malate increases the synthesis of nitric oxide (NO) in the blood, which dilates blood vessels, increases blood flow, regulates glucose uptake and optimizes mitochondria function. This increases nutrient delivery and waste product clearance from working muscles, improving muscle function and reducing fatigue. Citrulline supplementation has also been shown to increase human growth hormone (HGH) levels.

    L-Proline is an important amino acid responsible for cellular regeneration, tissue repair, and collagen building. It has beneficial cardiovascular properties, working to support balanced blood pressure levels and arterial elasticity.

    Electrolytes (Magnesium Bisglycinate, Magnesium Ascorbate, Potassium Gluconate)
    Bodily functions like muscle contractions and transmission of nerve impulses depend on electrolytes.

  • Magnesium – Magnesium is the fourth most abundant cation in the body and is needed by every cell in the human body. Magnesium is needed for nerve transmission, muscle contraction, blood coagulation, energy production, nutrient metabolism, bone integrity and cell formation. Low blood serum levels of magnesium have been associated with a number of chronic diseases including diabetes, hypertension, coronary heart disease, and osteoporosis (Kass, Weekes, & Carpenter, 2012).
  • Potassium – Potassium is the third-most prevalent mineral in the body and is needed for muscular contractions, blood pressure regulation, fluid balance, bone growth and nutrient digestion. The Food & Drug Administration recommends adults to consume 3,500 to 4,700 milligrams per day, yet only 2% of the American population actually consumes this quantity [10]. A meta-analysis that included 11 studies and 247,510 participants found that higher dietary potassium intake was associated with lower rates of stroke, reduced risk of coronary heart disease and cardiovascular diseases (D’Elia, Barba, Cappuccio, & Strazzullo, 2011).
