Now we have nano sized (really small). When things like vitamins, minerals, and plant bioactives are consumed they may only be digested and absorbed to a limited degree. For example, the recommended dosage of an herbal extract may be 200 mg. From the 200 mg, only 80 mg may be absorbed, the rest being broken down during digestion or simply excreted. When we talk about how much of some nutrient is being absorbed by the body, it is about bioavailability, which means how much of a given nutrient is available for the body to digest. All nutrients have different levels of bioavailability, which can also be impacted by gut health (gut flora/microbiome), age, genetics, and more. By reducing particles to nano size, and using NT to deliver them, we substantially increase bioavailability.
When that same herbal extract from our example above is reduced to a very small size and put inside special carriers such as structures called Inclusion Complexes, or Solid Lipid Nanoparticles (SLNs), then the absorption can increase substantially, sometimes to 90% or more. This is increased bioavailability. Because the absorption is much greater, we can ingest less, which can mean lower toxicity.
Remember, even an aspirin can put a toxic load on our organs. Further, because these special carriers hold the materials, you don’t taste them. A lot of herbs and plant bioactives have bitter and noxious tastes due to the alkaloids and other active components. We use NT to mask these bad tastes so we can still deliver an effective dose of the compound without you tasting it.
NT in foods is not new. It began seeing use in the food and pharmaceutical industry in the mid-1990s. There has been a lot of research and new developments since then, including safety research. There are certainly nanoparticles that are not good for our bodies, most of which may not be intentionally ingested or meant for ingestion such as tiny particles of metals from processing. None of those are in our products.
