Pack Nutrition Estro-Block is part of Pack Nutrition’s range of essentials, designed to be a staple in your supplement routine.


Estro-Block is a source of DIM (Diindolylmethane), which is produced from a natural compound found in cruciferous vegetables like broccoli, brussels sprouts and cabbage, and acts to balance hormone levels in both men and women by activating enzymes that breakdown excess estrogen. In addition, DIM also acts as a powerful antioxidant by reducing the damage caused by free radicals throughout the body, especially during times of physical stress like intense exercise.


For men, excess levels of estrogen can make it more difficult to increase strength and lean muscle mass, while for women, balanced hormone levels can help with improved general wellbeing, as well as performance in the gym.


Use Pack Nutrition Estro-Block to help with:

  • Balancing hormones
  • Management of excess estrogen levels
  • Minimising negative effects of elevated estrogen on muscle building and performance
  • Antioxidant support


Join the PACK, and manage hormone and estrogen balance to get the most from your training with Pack Nutrition Estro-Block!
