FAQs

While many immune system boosters on the market focus solely on providing immune support through vitamins, minerals, food extracts, or probiotics alone, G-NiiB Immunity+ (SIM01) takes a comprehensive approach. Recognising that 70% of immune cells reside in the gut, our immune system supplement formula combines three important live-friendly bacteria strains with Zinc, Vitamin B6, and B1, along with three types of dietary fibres. This holistic approach ensures that our supplement supports immunity but also energy boosting, gut health and regular digestion, setting it apart from other immune system booster options on the market.

G-NiiB Immunity+ (SIM01) sets a new standard in immunity supplements by incorporating a proprietary blend of live-friendly bacteria developed with advanced technologies such as AI, metagenomics and big data analysis by a prestigious university's faculty of medicine * . This award-winning formula is crafted to mimic the naturally occurring beneficial bacteria found abundantly in healthy individuals, promoting a balanced gut microbiome. The innovative, patented microencapsulation technology ensures a high survival rate for the bacteria, increasing the efficacy 5 times compared to unencapsulated strains, as demonstrated in research ◊ . Plus, with each sachet packed with over 1.5g of dietary fibres, it supports the proliferation and colonisation of these good bacteria in your gut. G-NiiB Immunity+ (SIM01) offers convenience without the typical capsule odour in a flavorful, easy-to-carry powdered sachet, making daily gut health support enjoyable and hassle-free.

◊ Compared with their unencapsulated friendly bacteria strains. Del Piano M. et al. Evaluation of the intestinal colonization by microencapsulated probiotics supplement bacteria in comparison with the same uncoated strains. J Clin Gastroenterol. 2010 Sep; 44 Suppl 1:S42-6.

While it may seem intuitive that more immunity-friendly bacteria strains lead to better health benefits, the reality is more nuanced. Each strain of friendly bacteria can have unique effects on our bodies, and they may even interact or compete with each other for food or living space, making the landscape of gut health complex and unpredictable.

We deliberately chose three curated bifidobacteria strains to formulate G-NiiB Immunity+ (SIM01). These strains are naturally abundant in the gut of healthy individuals and are particularly scarce in those who are unhealthy. Our aim is to provide precise supplementation rather than simply increasing the number of bio-culture strains without clear benefits.

Our studies have confirmed that the SIM01 formula effectively restores the formula's beneficial bacteria and promotes the growth of other beneficial bacteria in the gut. ¹² ¹³

The live-friendly bacteria must survive the journey through the digestive system to reach, grow, multiply and colonise in the gut to accomplish their mission. Without proper protection, many of them are destroyed by stomach acid and digestive enzymes, rendering them less effective. Additionally, without sufficient nourishment, the pouring beneficial bacteria may end up perishing.

G-NiiB Immunity+ (SIM01) has a cutting-edge world-patented microencapsulation technology. It is proven to effectively protect our friendly bacteria with 5 times more efficacy on survivability and colonisation. 2 billion rivals the effectiveness of 10 billion uncoated strains! It also comes with abundant dietary fibres to ensure the robust growth and thriving of our friendly bacteria in your gut, making this immunity supplement so effective.

G-NiiB Immunity+ (SIM01) uses micro-encapsulation technology from Italy to protect our friendly bacteria and ensure they will reach your gut alive. This world-patented-advanced technology (World Patent No. WO2013114185A1) uses a lipid shield to protect each friendly bacterium in a dormant state against gastric acid and the hostile digestive environment until the bacterium reaches your gut alive and colonises. A study proved that the subjects had the encapsulated strains, their good bacteria potency in the gut (the strains' survivability and colonisation) was comparable with the unprotected strains with 5 times higher doses by analysing subjects’ faecal samples. ¹⁴

Antibiotics may kill the good bacteria in your gut and sometimes upset your tummy. It is recommended to take G-NiiB Immunity+ (SIM01) at least 3 hours before or after consuming antibiotics. For people with specific medical conditions, especially immunocompromised individuals, it is always recommended to seek professional medical advice before starting any supplement regimen.

G-NiiB Immunity+ (SIM01) contains live-friendly bacteria abundant in the healthy human body. Its dietary fibres and other nutrients are present in natural foods. All its ingredients are natural.

For people with specific medical conditions, especially immunocompromised individuals, it is always recommended to seek professional medical advice before starting any supplement regimen.

G-NiiB Immunity+ (SIM01) contains vitamin B6 and vitamin B1, both of which are recognised as key vitamins for tiredness and fatigue. These nutrients help support your body’s natural energy production and reduce fatigue and feelings of exhaustion. Beyond that, they contribute to maintaining psychological and cognitive functions, which is essential for mental clarity and staying focused during busy days.

Yes, G-NiiB Immunity+ (SIM01) is a multifunctional supplement for tiredness and fatigue, offering essential B vitamins that support energy metabolism and help reduce fatigue. In addition to boosting vitality, the formula supports psychological and cognitive functions, helping you stay mentally sharp and alert throughout the day.

Our gut isn’t just for digestion — it helps produce short-chain fatty acids (SCFAs), which act as a key energy source for our intestinal lining. These SCFAs are made when beneficial bacteria ferment fibres in our diet. When your gut is off balance, this energy production may be reduced, leaving you feeling more sluggish. G-NiiB Immunity+ (SIM01) provides fibre-rich prebiotics and live-friendly bacteria that help restore this balance, while also delivering vitamin B6 and B1 — essential vitamins for tiredness and fatigue. If you’re looking for a gut-friendly supplement for tiredness and fatigue, this could be a well-rounded daily option.

Yes, it’s common to feel persistently drained after recovering from certain viral infections — even when you’re technically “better”. During these periods of lingering fatigue, supporting your body with the right nutrients becomes even more important. Vitamin B6 and B1 are known vitamins for tiredness and fatigue, as they help convert food into energy and support nervous system function. G-NiiB Immunity+ (SIM01) is a scientifically developed supplement for tiredness and fatigue, offering these key B vitamins at 30% of your daily requirement alongside gut-friendly bacteria for added support.

Modern lifestyles — full of stress, disrupted sleep, and poor diet — can leave us feeling constantly tired, even without an underlying illness. In many cases, low intake of key nutrients like vitamin B6 and B1 can be part of the picture. These are recognised vitamins for tiredness and fatigue, playing a vital role in how our bodies produce and manage energy. G-NiiB Immunity+ (SIM01) combines these nutrients with beneficial gut bacteria and prebiotics to offer a daily supplement for tiredness and fatigue that supports vitality from the inside out.

Yes, research suggests that a deficiency in key B vitamins — such as vitamin B6 and vitamin B1 — can impact the body’s normal psychological and cognitive functions. These nutrients are involved in the nervous system and help regulate mood and energy metabolism. When intake is consistently low, it may affect how the body responds to everyday stress. G-NiiB Immunity+ (SIM01) provides 30% of your daily recommended intake of both vitamin B6 and B1, helping you meet your body’s baseline needs for normal psychological and cognitive functions, emotional balance and mental energy.

It’s possible. Cognitive function — which includes memory, attention, and concentration — can be affected if the brain doesn’t receive sufficient nutritional support. Vitamins like B6 and B1 play essential roles in the normal psychological and cognitive functions and functioning of the nervous system and the brain’s energy supply. If your diet lacks these nutrients, it may contribute to feelings of mental fatigue or forgetfulness. G-NiiB Immunity+ (SIM01) contains both vitamin B6 and B1 at 30% of your daily recommended intake to help ensure your body has what it needs to support normal cognitive function.

Absolutely. G-NiiB Immunity+ (SIM01) includes zinc, which is an EFSA-approved nutrient contributing to the maintenance of normal skin, hair, and nails. So if you’re looking for a supplement for skin, hair and nails, this formula offers targeted support. Plus, zinc also contributes to cognitive function, making it a smart choice for overall wellbeing.

Zinc is a fundamental mineral in any effective supplement for skin, hair, and nails because it supports the normal development and maintenance of these tissues. It contributes to cell regeneration and also helps protect skin cells from oxidative damage caused by free radicals. That’s why many people looking for a supplement for skin, hair, and nails prioritise zinc as a core ingredient. G-NiiB Immunity+ (SIM01) contains zinc at 30% of the daily nutritional recommendation — providing support not just for immunity and energy but also as a trusted supplement for skin, hair and nails.

Yes — G-NiiB Immunity+ (SIM01) includes zinc, which makes it a suitable supplement for skin, hair and nails while also supporting your body’s natural defences and energy metabolism. Zinc is well known for contributing to healthy skin structure, hair growth, and nail strength, and also works as an antioxidant to protect against daily oxidative stress. If you’re searching for a supplement for skin, hair, and nails that also contributes to immunity and energy, G-NiiB offers a balanced approach in one convenient sachet.
