The cold, dreary days of winter take a toll on our health. It is not the cold itself that makes you sick, though; it is the bacteria and viruses that you get from your friends, family, pets and environment. And with the record-breaking low temperatures and historic snowfalls this year pushing more and more of us inside for longer periods of time, you are literally trapped in a small space with bacteria and viruses. To avoid getting sick you could become a hermit, avoiding contact with all potential germ-carriers, or you could naturally boost your immune system to better protect yourself against cold and flu viruses. The second sounds like the better option!

Syntol‘s unique combination of probiotics, prebiotics and enzymes enhances your immune system defences so you can fight off nasty winter bugs more easily. And if you are already at the mercy of a cold or flu, Syntol’s powerful formula can help get you better quicker – reducing the time you spend coughing, sneezing, blowing your nose and just feeling plain miserable.

Syntol AMD andProbiotics

Surprisingly, the key to stronger immune defenses lies in your gut. The lining of your intestinal tract is thought to be home to about 70% of your immune system. And although it may sound strange, consuming bacteria is actually one of the best ways to keep healthy during the winter – as long as they are the ‘healthy’ bacteria known as probiotics.

Syntol contains several billions of eight different non-competing strains of probiotic bacteria, mainly from the lactobacillus family. Research has shown that consuming probiotics may make the immune system more efficient at fighting off viral infections, especially those linked to the common cold and flu [1-4].

A study conducted in 2005 in Sweden found that shift workers who took a lactobacillus probiotic supplement had less than half the amount of sick days as workers who did not use the supplement [5]. Children who take lactobacillus supplements also miss fewer days of daycare due to being ill with respiratory infections [6].

The beneficial effects of lactobacillus are enhanced by combining it with other strains of probiotics, like bifidiobacteria, which is also found in Syntol. In a 2009 study, a group of children taking a lactobacillus supplement had 53% fewer fevers, 41% fewer coughs and 28% fewer runny noses compared to children who did not take any probiotics [7]. However, children taking a combination of lactobacillus and bifidiobacterium had 72% fewer fevers, 62% fewer coughs and 59% fewer runny noses. They also were sick for half the amount of time as children who did not take any probiotics.

Adding inulin helps boost the power of this probiotic blend even more. Inulin is a soluble fiber that is not digested by the body. It enhances the growth and activity of probiotic bacteria in the gut without helping any of the bad bacteria that are living there [8,9].

Syntol a Systemic Enzyme

Syntol contains a highly potent blend of enzymes that digest protein, cellulose and sugar. These enzymes, especially the proteases, are extremely effective at killing viruses throughout the body.

When a cold or flu virus attacks the body, it uses our own cells as tiny factories for producing duplicate viruses. Since one virus can multiply several thousand times, our whole body can be overrun by a viral infection very quickly. However, in order to replicate, a virus first has to integrate itself into our cells’ DNA. To do this, a virus takes advantage of its outer protein coating. Since protease enzymes literally eat through proteins, these enzymes can destroy the virus’ outer protein coating—effectively stopping the virus from reproducing and leaving it unprotected [10-12]. This leaves the virus open to destruction by antiviral treatments or your immune system.

Serrapeptase, a protein-digesting enzyme naturally produced by silk worms, is especially effective at treating the symptoms associated with winter infections [13-16]. It has been shown to reduce:

  • Sinus swelling and inflammation
  • Coughing
  • Phlegm
  • Pain
  • Stuffy and runny noses
  • Loss of sense of smell
  • Difficulty swallowing
  • Fever

Syntol is the only product that combines the power of prebiotics, probiotics and systemic enzymes into one capsule. While each of these natural ingredients effectively boosts the immune system and kills invading viruses on their own, together they combine to produce unparalleled protection and symptom relief from cold and flu viruses. Syntol is the brand to trust to protect you from getting a cold or flu and the one to turn to when you or a loved one needs help getting over a cold or flu quickly.
