Ostabulk Ingredients

  • Fenugreek extract

    Fenugreek extract may raise free testosterone levels by inhibiting its conversion to estrogen and dihydrotestosterone, which improves muscle strength and endurance. It could enhance muscle recovery time and aid in muscle repair by combating exercise-induced oxidative stress.

  • Nettle leaf extract

    Nettle leaf extract helps promote free testosterone levels by binding to the protein SHBG (Sex Hormone Binding Globulin), which typically binds to testosterone and renders it inactive. It possesses anti-inflammatory properties, which may aid in reducing exercise-induced muscle soreness and joint pain.

  • D-Aspartic acid

    D-Aspartic acid could encourage testosterone synthesis and may temporarily increase testosterone levels. It promotes muscle mass development and strength gains. It may improve neurotransmission by supporting neural health, which enhances focus and mental clarity during workouts or physical activity.

  • Korean red ginseng

    Korean red ginseng is a potent herb with adaptogenic properties. It helps the body adapt to physical stress, increasing endurance and improving workout performance. It may improve blood circulation to the muscles, aiding muscle recovery and rejuvenation. Korean red ginseng could increase muscle recruitment, reduce fatigue, and promote muscle growth.

  • Magnesium Oxide

    Magnesium oxide could promote muscle contractibility, nerve function, and protein synthesis. It supports energy production at the cellular level and facilitates the conversion of food into energy, allowing muscles to perform at their best. It could stimulate the ribosomes in muscle cells and positively affect muscle protein synthesis. 

  • Vitamin D3 and K1

    Vitamin D3, also called cholecalciferol, may help restore the quality and strength of muscle fibers. Such action aids in faster recovery and improves muscular growth and overall performance. It could enhance muscle contractility, increase bone density, and safeguard against the risk of fractures.

    Vitamin K1 could benefit bone and muscle metabolism, promote muscle growth, and increase muscle fiber density. Such effects may lead to the growth and development of lean muscle mass.

  • Vitamin B6

    Vitamin B6 supports the metabolization of amino acids, the building blocks of protein, which helps promote muscle building and repair. It may reduce recuperation time, allowing you to recover faster after intense workouts. B6 could improve sleep patterns and quality, creating an environment that supports muscle growth and recovery.

  • Zinc

    Zinc promotes protein synthesis, which helps muscle recovery and growth. It could affect myogenesis, which is the formation of skeletal muscle tissue. Adequate zinc levels aid in muscle regeneration and reduce muscle fatigue. It may also regulate testosterone levels for optimum muscle strength and overall energy.

  • Bioperine

    Bioperine is a patented and enhanced black pepper fruit extract that may improve nutrient absorption and bioavailability. It could increase bone strength, improve physical performance, and provide energy to muscle cells.
