nitric oxide booster*

improves absorption


Astravar® boost the power of your pre-workout supplement.


is an all-natural, plant-derived compound that is extracted from highly fractionated Panax notoginseng and Astragalus membranaceus. Research suggests that Astragin may improve the absorption of various nutrients at the cellular level. This means that a greater amount of these nutrients are transported from the blood stream into cells, for truly improved bioavailability. Astragin helps to enable up to 62% more L-arginine to become bioavailable so it can be converted to nitric oxide. Research suggests that the ingredients in Astragin can increase eNOS (endothelial nitric oxide synthase), the enzyme that prompts nitric acid production in endothelial cells.*

Astragin Benefits

  • Increases absorption of performance enhancing ingredients.*
  • Increases nitric oxide production.*
  • Increases ATP production.*
  • Increases muscle glycogen replenishment.*

Red Beet Root

is naturally high in nitrates (NO3), which are believed to improve athletic performance. A study led by the University of Exeter, published in 2009 in the Journal of Applied Physiology, pointed to the benefits of NO3, concluding that they boost a cyclist's endurance. Nitrates are helpful to athletes because they quickly bring oxygen to muscles, essentially making the more difficult efforts easier. Additionally, Bailey et al. (2009) found that beet root supplementation can reduce the O2 cost of exercise, suggesting that beet root supplementation allows for high-intensity exercise to be tolerated for an extended period of time.*

Red Beet Root Benefits:

  • Increases nitric oxide.*
  • Improves endurance.*

rhodiola Rosea

belongs to Crassulaceae family of flowering plants that grow throughout the mountainous regions in the higher latitudes and elevations of the Northern hemisphere. Research has suggested that Rhodiola rosea can help increase endurance and time to exhaustion. Further research indicates that chronic consumption of Rhodiola rosea increases fatty acid consumption and helps to reduce muscle damage after exercise. Additionally, studies have shown that Rhodiola rosea can have a mood boosting effect. It is believed that the reason for this is an increase in beta-endorphins, similar to what you would feel after exercise.*

Rhodiola Rosea Benefits:

  • Increases endurance.*
  • Boosts mood and mental focus.*
  • Helps utilize fat as energy source.*
  • Helps prevent muscle damage post exercise*
