In order to contaminate and then infect the body, a microbe must first cross a physical barrier such as the skin or mucous membranes of the airways. Some of these barriers have active immune functions and are able to quickly neutralise intruders.
One such example is the skin’s outer layer, the keratinised epidermis, which secretes antimicrobial mini-proteins (defensins) and substances able to inhibit excessive microbial growth, such as lactic acid.
The same principle applies to the digestive tract mucosa which secretes lysozyme and lactoferrin.
Many immune cells responsible for patrolling and eliminating intruders are also present at barriers, such as mastocytes and intraepithelial lymphocytes on the skin, and neutrophils on the cornea, the clear outermost layer of the eye.
These barriers are also home to commensal bacteria, which live in symbiosis with us and which constitute an additional biological obstacle to potential attackers.
The majority of microbes are thus prevented from entering the body, though some will inevitably succeed in breaking through.
When anatomical barriers are breached, the body must first identify the intruder (the ‘non-self’).
It therefore has a largely specific second line of defence: innate immunity. Receptors located on the surface of certain cells (including ‘dendritic cells’) are able to attach themselves to ‘common’ types of intruders, which they recognise without having come across them before. It’s as if we are born with a generic list of key enemies likely to infect us, that have several distinctive patterns and signs (pathogen-associated molecular patterns or ‘PAMP’).
For greater reactivity, our receptors are also able to recognise molecules made by human cells that have been infected by these intruders (danger-associated molecular pattern or ‘DAMP’).
Several immune players then enter the fray.
When an intruder is encountered for the first time, a second system is set in motion: acquired immunity.
White blood cells called lymphocytes (T and B lymphocytes) learn and memorise the specific nature of the intruder in order to attack it more effectively should it reappear in the future. To do so, these lymphocytes need helpers, antigen-presenting cells (dendritic cells, monocytes…), which digest the intruder and reduce it to fragments.
Some of these lymphocytes then develop into memory cells which live for years or even decades. And when they re-encounter their specific aggressor, they are able to transform themselves into antibody-producing cells (plasmocytes).
Also called immunoglobulins (igg, igm, iga, ige…), antibodies bind specifically to the pathogens they’ve learnt to recognise, and protect the body in several ways:
Vaccination is based precisely on this acquired (or adaptive) immunity, a key role of which is to produce specific antibodies to fight a targeted aggressor.
Innate and acquired immunity interact and influence each other during the immune response. Many other players become involved in this process (1).
The immune response ceases once the intruder is eliminated from the body.
Zinc is a trace-element present in every cell in the body. It supports normal immune system function through at least three distinct mechanisms (2):
In general, the body absorbs between 15% and 40% of the zinc present in food, the main sources being meat, nuts, fish and seafood, but zinc supplements can help to both compensate for any shortfall and normalise the immune system. Zinc orotate (Zinc Orotate) and zinc bisglycinate (Advanced Zinc Lozenges) are the forms best-absorbed and best-tolerated by the body.
A traditional Native American remedy, echinacea is a plant extensively studied for its potential to modulate the body’s defence system.
It is now one of the most widely-used medicinal plants in Europe and North America.
While we don’t yet know all its precise mechanisms of action, echinacea appears to stimulate production of certain cytokines and help to activate various immune cells (macrophages and lymphocytes), as a result of its high content of alkylamides and echinacoside (3-4), especially when taken in the form of a dietary supplement (Immunity booster).
Colostrum is a substance produced by all female mammals in the first days after giving birth.
Rich in proteins and antibodies, key molecules for the immune system and the fight against pathogens, it also contains vitamins, minerals, anti-infectious molecules (lactoferrin and lysozyme, in particular) and zinc, which helps to normalise the immune response.
Some supplements in the form of gastro-resistant capsules (such as Colostrum) maximise the substance’s benefits.
Like echinacea, ginseng is one of the plants termed ‘adaptogens’ which help the body defend itself against attack.
It is its high content of ginsenosides which gives it this ability to support the immune system (5-6), by stimulating defence cells such as lymphocytes, and by supporting production of interferons, cytokines produced naturally when pathogens enter the body.
For optimal effects, it’s best to choose a ginseng supplement standardised in ginsenosides (such as Super Ginseng).

I am merely judging the delivery system, which was flawless. It wouldn't make any sense to comment on the efficacy of the supplements, since that is only possible on a statistical basis. Even if something doesn't improve, that doesn't have to mean that the supplement doesn't work, since one doesn't know how it might have worsened without the supplement and the opposite might also apply, since many symptoms are psychosomatic and the supplement might provide a placebo effect.
