FitNutrients+ is a superior multivitamin/mineral blend, featuring metabolically active B vitamins and a highly absorbable mineral complex, ensuring maximum nutrient utilization. Beyond providing fundamental nutrition, this all-encompassing formula includes specialized components aimed at enhancing cellular energy generation and boosting mental and physical vitality.*


FitNutrients+ offers enhanced support for both mental and physical energy production and detoxification. Each ingredient's unique mechanism within FitNutrients+ is detailed below, accompanied by an overview of the multivitamin and mineral components that form the core of the FitNutrients formulations.

  • N-Acetyl-L-Cysteine is a modified form of the amino acid L-cysteine plays a crucial role in boosting the body's antioxidant capabilities. It significantly contributes to the synthesis of glutathione, an essential element in antioxidant and detoxifying enzymes.*[1]
  • Acetyl-L-Carnitine is derived from an amino acid, this compound is vital in the metabolism of fats and carbohydrates. It aids in energy generation by moving long-chain fatty acids into the mitochondria for beta-oxidation, leading to the production of ATP (adenosine-5’-triphosphate).*[2,3]
  • Alpha-Lipoic Acid (ALA) is unique in being both water- and fat-soluble, found within and outside cells, including mitochondria. It acts as a metabolic coenzyme and combats free radicals, aids in regenerating vitamins C and E, boosts glutathione levels in tissues, and helps maintain the correct balance of reduced and oxidized coenzyme Q10 within the mitochondria.*[4,5]
  • Milk Thistle Extract has long been used for liver health, the active component in milk thistle, Silymarin, offers antioxidant support, neutralizes toxins, and potentially protects liver health. Its liver-specific benefits include managing fat peroxidation and fibrous tissue formation, supporting immune and inflammatory responses, and aiding in protein synthesis for normal liver regeneration.*[6,7]
  • Theacrine is chemically akin to caffeine but distinct in its effects, theacrine, a purine alkaloid, does not cause habituation. It acts as a dopamine receptor agonist, enhancing dopamine signaling linked to improved mood, increased mental focus, and heightened energy.*[8]
  • Green Tea Leaves, rich in polyphenols, especially epigallocatechin-3-gallate (EGCG), these leaves offer potent antioxidant properties, DNA protection, induction of detoxifying enzymes, and support for gene signaling involved in cell growth, development, and apoptosis. They may also play a role in fostering healthy gut bacteria.*[9,10]
  • Broccoli Seed Extract contains glucoraphanin, which metabolizes into the active sulforaphane. These components are recognized for their effects on antioxidant activity, detoxification, cellular metabolism, and cell-life regulation, linking cruciferous vegetable-rich diets to health.*[11,12]
  • Resveratrol is a phenolic compound found in grape skin, certain berries, and nuts, provides antioxidant support, guarding against oxidative damage and cognitive decline effects.*[13,14]
  • Huperzine A (HupA) is an influencing ion channels, HupA is associated with learning and memory health. It may affect acetylcholine levels, a neurotransmitter, thereby supporting cognitive health as evidenced in animal studies and phase IV human trials.*[15,16]
  • Shilajit is a phytocomplex rich in minerals and bioactive elements like fulvic acid, it consists of rock humus, minerals, and organic substances formed from rock layers and marine organisms. In ayurvedic and siddha medicine, it's recognized as a rasayana, celebrated for its rejuvenating properties, including enhancing physical performance and reducing fatigue. Recent studies indicate its antioxidant properties and potential to regulate heavy metal distribution and metabolism.*[17]
  • Bacopa monnieri is an ayurvedic herb known for its cognitive enhancement, cytokine modulation, and stress-relief capabilities. Its benefits are attributed to its ability to scavenge free radicals and protect DNA from damage.*[18,19]

Foundation Formula Discussion for FitNutrients+

Proper nutrition is essential for overall health and well-being, contributing to a robust immune system and better health outcomes. The body utilizes dietary macronutrients—proteins, fats, and carbohydrates—to generate energy needed for various physiological functions. Micronutrients, comprising vitamins and minerals, are required in smaller amounts. They play a critical role in food-to-energy conversion, tissue and DNA repair, neurotransmitter and hormone production, xenobiotic and medication detoxification, and in maintaining growth, reproduction, and general health, despite not being direct energy sources.*[20-22]

The Dietary Guidelines for Americans 2020-2025 (DGA), along with additional data from the USDA and other bodies, highlight a micronutrient deficiency in the American diet.[23-25] Factors like mass food production, storage methods, unhealthy food choices, and nutrient-depleting cooking practices contribute to this deficiency. Moreover, the percent daily values (%DV) for micronutrients, based on basic needs of a healthy individual from a specific demographic, may not represent the optimal amounts for all, particularly those with chronic illnesses.*[22,24,26]

The DGA identifies significant deficiencies in potassium, dietary fiber, calcium, and vitamin D in American diets.[23] Other nutrients needing attention due to low intake or life stage requirements include vitamins A, B6, B12, C, E, and folate; minerals like magnesium and iron; and choline.[23,27,28] NHANES data indicate widespread deficiencies in vitamins A, C, D, E, and zinc—key to immune health.[25] These deficits largely stem from inadequate consumption of nutrient-rich foods such as vegetables, fruits, whole grains, and dairy.[23] Multivitamin/mineral supplements are thus recognized for their value in addressing these dietary gaps.*[21,25,26,29-31]

FitNutrients+ is formulated to meet foundational nutritional requirements across various protocols and life stages, offering:

Balanced Nutrient Profile: Maintaining a balance between micronutrients is crucial as imbalances can lead to competitive absorption or displacement at metabolic/cellular levels. FitNutrients+ features a balanced mix of essential nutrients, including calcium, magnesium, vitamins C and E, bioactive folate, bioactive B12, a B vitamin complex, beta-carotene, and trace elements.*

Bioavailable Nutrient Forms: The micronutrients in FitNutrients+ are in bioactive forms for optimal absorption and use. The formula includes Albion® patented mineral chelates and complexes, recognized for their bioavailability. It also contains natural vitamin E, more bioavailable than synthetic forms, along with mixed tocopherols, and bioactive 5-MTHF (methyltetrahydrofolate) in the form of Quatrefolic® for enhanced stability and absorption.*[32-36]

Energy Production and Stress Response Support: FitNutrients+ provides abundant B vitamins, crucial as coenzymes in glycolysis, oxidative phosphorylation, amino acid, and lipid metabolism. Adequate levels of B vitamins are vital for energy production, cell growth, division, and support for nervous system function. These vitamins function cooperatively and are particularly beneficial for individuals with stressful lifestyles.*[37-40]

Antioxidant Protection: A combination of vitamins E and C, selenium, zinc, beta-carotene, and trace elements in FitNutrients+ offers comprehensive antioxidant activity. These elements work synergistically to regenerate each other and maintain consistent antioxidant levels both within and outside of cells.*[41,42]

Detoxification Support: The detoxification of xenobiotics, including environmental pollutants and medications, is a complex process requiring micronutrients, phytonutrients, energy, and robust antioxidant support. FitNutrients+ contains significant levels of bioavailable riboflavin, niacin, folate, and B12, supporting phase I detoxification. Additionally, beta-carotene, vitamin C, tocopherols, selenium, zinc, and manganese aid in managing reactive intermediates formed between phase I and II detoxification processes.*[42-44]

In summary, FitNutrients+ delivers foundational multivitamin and mineral support, designed to bridge dietary nutritional gaps and foster optimal wellness. It integrates a select blend of ingredients specifically chosen to augment mental and physical energy production and detoxification processes.*
