WHAT IS RESPIRATORY
IMMUNE BALANCE?
Respiratory immune balance is the ability of the airways and lungs to return to a normal healthy state quickly and completely after inflammation.
Inflammation is the natural process of neutralising and removing dangerous foreign particles and pathogens.
Immune balance relies on checkpoints in specific immune cells that recruit and activate other immune cells to fight when needed; reduce these immune cell numbers when finished; and reorient immune cell activity to heal and repair damaged tissue after the threat has been removed.

What are macrophages &
why are they so important?
Macrophages are innate immune cells that may reside in both the epithelial cells of lungs (alveolar macrophages) and circulate in the blood as a type of white blood cell.
Macrophages play multiple important roles in detecting and fighting pathogens and healing damaged tissue. Macrophage activity can change based on environmental cues.
Macrophages have three activation states – the ability of macrophages to change states to perform multiple different functions places them at the centre of immune balance. Because macrophage activity can be influenced by environmental factors, including diet, they are also a convenient target for interventions such as BerriQi, to help re-establish balance.

Why does it take
so long to recover
from respiratory
infections?
Typical respiratory infections are short-lived, with the average rhinovirus infection lasting approximately 72 hours.
Lingering Symptoms
However, symptoms of inflammation such as runny nose, mucus production, cough, and shortness of breath can persist long after, reducing productivity and limiting quality of life. Because macrophages are so sensitive to the environment, which often carries additional stressors such as dust, pollution, and allergens, some macrophages may not seamlessly progress through all the activation states to resolution of inflammation, leading to continued inflammation and symptoms of healing.
The immune system may require additional anti-inflammatory cues from diet, and macrophages may need additional prompting from bioactive molecules to progress through activation states until the immune system has calmed to its normal baseline level of alertness and activity.
“Our lungs face environmental
stressors such as pollution,
allergens, and pathogens everyday.
Supporting our respiratory immune
system to respond in proportion
to actual threats, quickly restore
calm and return to balance the
rest of the time is key to ensuring
we can breathe easily through
clear airways.”
– Starin Mckeen, Scientist

Why do we care?
Respiratory infections impact everyone. Even the most minor infections and their resulting inflammation are inconvenient and reduce productivity and quality of life, often for an extended period of time because inflammation can last much longer than the infection itself. More severe respiratory infections that overwhelm the immune system contribute to 2.6 million deaths annually, and many more lead to chronic respiratory disease onset because of immune dysregulation and uncontrolled, inappropriate inflammation.
How can BerriQi help?
BerriQi helps to move the immune system from fight mode into healing mode and further resolve symptoms of inflammation. This reduces the severity of symptoms, shortens the time of sickness, and prevents long term damage.

Why IS POLLUTION
SO DANGEROUS?
The smaller the air pollutant, the more dangerous it is to human health. High levels of particulate matter smaller than approximately 2.5 micrometers (PM2.5) are associated with poor health outcomes and many of the leading causes of death. At this microscopic size they are small enough to infiltrate deep into our lung tissue and enter our bloodstream. In our lungs they can cause ongoing inappropriate inflammation, with this chronic long-term inflammation causing scarring and making breathing more difficult. Once in our bloodstream, PM2.5 can cause further inflammation and promote plaque formation – thereby increasing blood pressure and increasing risk of stroke.
WHY DO WE CARE?
The World Health Organisation estimates that 99% of the global population breathes air containing levels of pollutants exceeding healthy limits, with at least 80% of the global population living in high pollution environments. Air pollution is one of the leading risk factors for death, attributing to 11.65% of deaths globally.
What happens when fine particles get into your lungs?
- When you live in a city with air pollution, air containing oxygen and fine particles travels down the trachea (windpipe) and through the bronchiole tubes to the air sacs.
- The fine particles lodge in the air sacs, causing irritation. Eventually the air sacs become thick, stiff and scarred from inflammation. The lungs harden and don’t inflate easily.
- Breathing becomes difficult and uncomfortable. You feel breathless, weak and tired.
How can BerriQi help?
BerriQi helps to support the lungs to repair the inflammatory damage caused by particulates. BerriQi helps people living in high pollution environments take bigger deeper breaths through clear airways, while preventing long term damage and reducing risk.

How does BerriQi
restore respiratory
immune balance?
BerriQi contains high concentrations of bioactive polyphenols and anthocyanins which have broad antioxidant and anti-inflammatory effects, as well as more specific effects on alveolar macrophages that leads to reduced mucus production and reduced collagen in the interstitial space where gasses are exchanged.

ANTIOXIDANT
ACTIVITY
prevents damage to delicate tissue in the airways by absorbing and neutralising oxidants such as reactive oxygen species. Reactive oxygen species are inhaled in pollution, but they are also produced by immune cells which secrete as part of the chemical warfare against invading pathogens.

ANTI-INFLAMMATORY
ACTIVITY
means the number of immune cells in the lungs decreases, because fewer immune cells are recruited. This reduction in immune cell number creates more space for the lungs to expand, so bigger and deeper breaths can be taken.

REDUCED MUCUS
PRODUCTION
may be a result of having fewer excess immune cells to remove from the lungs. The reduction in cough allows tissue to heal faster.

REDUCED COLLAGEN
in the interstitial space of lungs is the final step in healing, allowing gasses to be exchanged between air and the blood stream across thin alveolar membranes. The reduced collagen also restores stretch and lung capacity, which may have been compromised contributing to shortness of breath.

What are polyphenols
& how do they help
protect lungs?
BerriQi contains high concentrations of bioactive polyphenols and anthocyanins which have broad antioxidant and anti-inflammatory effects, as well as more specific effects on alveolar macrophages that leads to reduced mucus production and reduced collagen in the interstitial space where gasses are exchanged.

What are anthocyanins & how
do they help protect & repair lungs?
Anthocyanins are a class of polyphenols known for their distinctive colour that range from purple to pink to red.
Berries produce anthocyanins in the final stages of ripening. Berries grown in New Zealand produce nearly 30% more anthocyanins due to increased UV intensity. Over 600 distinct structures of anthocyanins have been identified and characterised
While all anthocyanins are potent bioactives, not all structures of anthocyanins have the same type of bioactivity. The specific type of anthocyanin that Boysenberries produce have the unique ability to bind to a receptor in macrophages that triggers a signalling cascade altering the activity of the macrophage.
The macrophage activation state progression from M1 to M2 reduces inflammation due to reduced immune cell recruitment. In this state, macrophages promote healing by prompting

collagen production to support and protect damaged cells while they repair and regenerate.
When the anthocyanins in BerriQi prompt the macrophage activation state to progress from M2 to M2C, several molecular switches are flipped. Amongst these are:
– MMP9 is turned off: Matrix Metalloproteinase-9 refers to a gene that codes for a proteinase that directly breaks down extracellular matrices such as abnormal collagen.
– TIMP1 is turned off: Tissue Inhibitor Metalloprotease 1 inhibits MMP9 activity and promotes increased collagen deposition.
Together, these molecular switches allow for the breakdown of collagen that was deposited for short-term support. This collagen breakdown restores stretch, increases lung capacity, and improves gas exchange between the air and the blood stream.

PAQ+ Boysenberries
& Apple Bioactive
Complex.
BerriQi isn’t just boysenberries. It is the combination of both boysenberries and apples that give BerriQi it’s therapeutic effect. Standardized to 15% of the total polyphenols present, PAQ+ comprises of the anthocyanins from boysenberries as well as the procyanidins and quercetin from apple.
Procyanidins
Flavonoids that strengthen vascular integrity and modulate immune response
Anthocyanins
Pigment antioxidants with potent anti-inflammatory and antiviral properties
Quercetin
A flavonol renowned for immune support and viral interference
PAQ+ helps BerriQi work in one hour:
PAQ+ supports enhanced efficacy due to synergistic effects:
The three classes of polyphenols interact to stabilize each other and amplify anti-inflammatory, immune-modulating, and tissue-healing effects. Additionally, the synergistic interaction between anthocyanins and other polyphenol classes promotes a phenomenon known as ligand swamping, where multiple polyphenolic compounds saturate metabolic enzymes and transporters, reducing first-pass metabolism and further increasing overall polyphenol bioavailability.
