Just Thrive® Ultimate IgG

Ultimate IgG Protect is a highly concentrated antibody formulation that provides complete immune support

Antigens, Antibodies, And The Fight For Your Health

Viruses, infectious bacteria, environmental toxins, and more! These health villains – known collectively as antigens – seem to be lurking EVERYWHERE. 

To thwart the antigen attack, your immune system sends out antibodies – also known as immunoglobulins – which are your front-line soldiers. Your body’s most important and abundant soldier is called Immunoglobulin G, or IgG! 

Under ideal conditions, your body is able to produce adequate amounts of IgG. But, in times of high stress and uncertainty, or when your system gets slowed down by something new and unfamiliar, your production of IgG can be greatly impacted.

That’s where Just Thrive Ultimate IgG can help.

This powerful purveyor of immune health aids your body in two equally important ways:

  • It sends in immunoglobulin “troops” to help keep your immune system from getting overwhelmed
  • It helps keep your immune system in check – No overreacting… no underreacting… no attacking itself!

When it comes to the bad guys, the last thing you want is to mount a defense that is either…

Too weak that it can’t win out, or... 

Too strong that it ends up causing more harm to your body.

Ultimate IgG helps give your immune system the tools it needs to respond the right way

Smart, balanced, and impressively effective.

How IgG Supports Your Immune And Gut Health

IgG, is an antibody – a protective protein that your immune system produces when it senses an invader. IgG antibodies patrol your body for antigens and spring into action when they run into anything that’s not supposed to be there, such as...

  • Viruses
  • Pathogenic bacteria
  • Fungi
  • Environmental toxins
  • Mold toxins

When IgG antibodies catch an invader, they bind to it so they can’t escape. They neutralize the germ or toxin, so it can’t do any damage. Then they safely remove the antigen from your body. Problem solved

Supporting the Health And Protection of Your Gut Barrier

Your gut is lined by a protective barrier with two crucial jobs. It selectively sends nutrients and healing compounds into your bloodstream for delivery to your cells and organs to fully nourish your body. Concurrently it keeps toxins locked safely inside the gut and prevents them from escaping into your bloodstream.

But bad bacteria and other toxic substances (like pesticide residue on apples, for example) can quickly compromise your gut barrier and weaken it. If that happens, toxins can sneak into your bloodstream and travel anywhere in your body… and that can take an enormous toll on your health.

Ultimate IgG provides an extra level of support in your gut by seeking out and neutralizing harmful bacteria BEFORE its impact can be felt. By taking down antigens, Ultimate IgG:

  • Supports healthy intestinal function
  • Encourages optimal health and strength of your gut barrier
  • Increases nutrient absorption to support healthy digestion
  • Boosts the effectiveness of probiotics

Ultimate IgG and Probiotics: Working Together

Immunoglobulin G (IgG) works together with probiotics to nurture the number of beneficial gut bacteria while encouraging the health and protection of your gut barrier. By eliminating harmful antigens, IgG makes it easier for probiotics to survive and thrive in the gut. 

IgG and your probiotic make a super powerful 1-2 punch that supports optimal gut health and intestinal barrier function.
