Essentials Vitamin D3 Complex combines the very best of modern science and natural plants with proven healing properties.

Here at IgBioscience we worked hard to find a specific combination of natural extracts and vitamins to enhance and support our Immustem UK Colostrum and IgTurmeric+ range.

Working with scientists and nutritionists, we’ve produced a unique and effective combination.

We’ve taken two of the most powerful proven and natural immune boosting plants – Elderberry and Lions Mane and combined them with Vitamins D3, C, A and  Zinc.

We’ve used the latest technology for the Vitamin C – it’s Liposomal meaning it’s coated in a lipid – fat molecules. These lipids coat all of our cells – so they recognise the lipid Vitamin C instantly and allow it into the cell. It’s also used by the mRNA Covid Vaccine manufacturers to coat the vaccine so it gets delivered directly into the cells for maximum effect. Vitamin C is known for being hard to absorb and this technology transforms its ability to work in our bodies.


Hippocrates called it his “medicine chest”.  Packed with Vitamins and minerals that regulate and modulate the immune system. Of all the natural plant remedies, Elderberry is top of the list.
According to the European Cytokine Network Elderberry – or Sambucal Nigra is known for its strong antiviral properties especially against different strains of the influenza virus. Further research has shown it activates the immune system and increases inflammatory Cytokine production.


Cytokines are cell signalling molecules that aid cell to cell communication in immune responses and stimulate the movement of cells towards sites of inflammation, infection and trauma. So they’re crucial for managing the response of the immune system.


There’s good reason why vitamin D is called “the sunshine vitamin.” When your skin is exposed to sunlight, it makes vitamin D from cholesterol. The sun’s ultraviolet B (UVB) rays hit cholesterol in the skin cells, providing the energy for vitamin D synthesis to occur.

It instructs cells to absorb Calcium and Phosphorous – essential for strong and healthy bones. But that’s not all.

This vitamin plays a critical role in promoting the immune response. It has both anti-inflammatory and immunoregulatory properties, and is crucial for the activation of immune system defences (Central European Journal of Immunology 2018)

Vitamin D is known to enhance the function of immune cells, including T cells and macrophages, that protect your body against pathogens (British Society for Immunology 2011).

In fact, the vitamin is so important for immune function that low levels of vitamin D have been associated with increased susceptibility to infection, disease, and immune-related disorders (Journal of Investigative Medicine 2011).


A large white shaggy mushroom, known for its medicinal benefits for 1000’s of years. Research shows it boosts the production of the microbiome in the gut which prevent pathogens from entering the body. The microbiome is the cornerstone of the immune system.

Also, it’s rare among mushrooms as it boosts the production of bioprotein nerve growth factor (NGF) (Int Journal Med Mushrooms 2013) and myelin (the insulation around nerve fibres).

As we age, our brain’s ability to form new connections (neural plasticity) declines, causing many of the cognitive issues associated with growing older. It’s been shown that Lions Mane can help with the repair of nerve damage, ameliorate the symptoms of Alzheimers, and the symptoms of autoimmune disorders such as MS.


Vitamin C is one of the most proven, well-established and powerful immune boosting, anti-oxidant, anti-aging, anti-viral, anti-pathogenic and antitoxin nutrients known to man. These benefits have been clearly demonstrated over time and yet human beings are amongst only a handful of animal species that cannot produce their own supply of vitamin C. So we have to source it from food or via supplementation.

Liposomal Vitamin C has been scientifically proven to deliver more Vitamin C into your body than traditional Vitamin C supplements.

Most Vitamin C supplements are partially destroyed in the hostile environment of the gut, and much of what’s left is “peed” out of the body. We avoid this by wrapping the Vitamin C inside ‘Liposomes’.

Liposomes are tiny, nano-sized bubbles that mimic the body’s own cell membranes and are designed to protect the Vitamin C as it travels through the body. Liposomes also have the ability to travel through the body’s cell walls aiding and accelerating absorption. This means that the Vitamin C is being delivered directly into the cells of your body, without being degraded. (Journal of Nutrition and Metabolic Insights 2016)


Vitamin A plays a vital role in maintaining your body’s natural defences. According to the Journal of Clinical Medicine 2018 it plays a critical role in enhancing immune function.

This includes the mucous barriers in your eyes, lungs, gut and genitals which help trap bacteria and other infectious agents.

It’s also involved in the production and function of white blood cells, which help capture and clear bacteria and other pathogens from your bloodstream.

This means that a deficiency in vitamin A can increase your susceptibility to infections and delay your recovery when you get sick (American Journal of Clinical Nutrition)

Additionally it’s vital to maintaining good vision. The vitamin is needed to convert light that hits your eye into an electrical signal that can be sent to your brain. In fact, one of the first symptoms of Vitamin A deficiency can be night blindness, known as nyctalopia.

Night blindness occurs in people with vitamin A deficiency, as the vitamin is a major component of the pigment rhodopsin. Rhodopsin is found in the retina of your eye and extremely sensitive to light. People with this condition can still see normally during the day, but have reduced vision in darkness as their eyes struggle to pick up light at lower levels.


Zinc is a key micronutrient and mineral that is essential for the body in numerous ways, it keeps the immune system strong, helps heal wounds, and supports normal growth. A lack of zinc can make a person more susceptible to disease and illness. It is responsible for several functions in the human body, and it helps stimulate the activity of at least 100 different enzymes. It affects how our cells respond to infections and can help keep inflammation under control.

According to the National Institute for Health, it helps the immune system fight off invading bacteria and viruses. It’s also crucial for the manufacture of proteins and DNA and for the normal functioning of cells. It affects multiple aspects of our immune system.

Our bodies can’t make zinc, which means that it must come from our food or from supplements. The element is naturally found in many different foods, such as beans, shellfish, and wholegrains.

Researchers say they have gained a key insight into how zinc helps the immune system fight infection. One study shows that zinc stops the immune system from spiralling out of control and the researchers say the findings could also explain why taking zinc supplements at the start of a cold can stem its severity. If you’re low in zinc, you may find cuts and scrapes take longer to heal, you may have diarrhoea, and you’re more prone to getting ill.
