Most people look at one thing: concentration<\/strong>.<\/p> The more milligrams on the label – the “better” the product. This approach stems from intuition: more substance should mean stronger action.<\/p> The problem is that the body does not act according to the label.<\/p> In practice, it is not only the amount of substance that matters, but:<\/p> <\/p> This means that the high content of the active compound does not guarantee its use<\/strong>.<\/p> You can take in a large amount of a substance that will not be assimilated for the most part. That’s the difference between administration and accessibility<\/strong>.<\/p> In classic plant extracts, the strategy is simple: increase concentration.<\/p> However, many bioactive compounds – especially polyphenols (such as curcumin, resveratrol and quercetin) – are characterized:<\/p> – low solubility, The result?<\/p> High number on the label, but low real-world effectiveness.<\/p> This is due to physiology and pharmacokinetics<\/strong>.<\/p> This is a key moment that is most often overlooked.<\/p> After oral administration, the substance goes through several stages:<\/p> <\/p> And only then can it enter the bloodstream in active form.<\/p> Losses occur at each of these stages.<\/p> In practice, this means that even a well-prepared extract can lose much of its potential before the body has time to use it systemically [1].<\/p> In the case of many polyphenols:<\/p> <\/p> This is why concentration alone is not proof of effectiveness<\/strong>.<\/p> Curcumin has very low oral bioavailability.<\/p> Reasons: In clinical trials, even high doses do not translate into high concentrations of the free form in the blood [2].<\/p> Resveratrol is well absorbed, but its systemic bioavailability is very low.<\/p> Why?<\/p> – rapid conversion to metabolites (glucuronides, sulfates), Effect:<\/p> Much of the dose disappears before it reaches its active form in circulation [3].<\/p> Quercetin:<\/p> – has limited solubility, Its bioavailability is variable and strongly depends on the form of administration [4].<\/p> The differences between the forms are not theoretical.<\/p> They are visible in parameters such as:<\/p> – Cmax<\/strong> – maximum blood concentration In classic forms:<\/p> – Cmax is low, In well-prepared carrier systems (e.g., lipids):<\/p> – There is an increase in AUC, The final effect depends on the quality of the formulation – this determines whether the substance will actually be used by the body.<\/p> Full spectrum extracts contain a broad spectrum of naturally occurring compounds in the plant, including:<\/p> – cannabinoids, Their importance is not just in their presence, but in the relationship between them<\/strong>.<\/p> From the point of view of biochemistry, they act as a dynamic system in which: This phenomenon is referred to as synergy<\/strong>.<\/p> However, this does not mean that every full spectrum extract automatically works better.<\/p> The key remains: Without the proper form, even a complex extract may have limited bioavailability.<\/p> Isolates are single, isolated chemical compounds of high purity.<\/p> They are obtained through processes such as Their main advantage is control and precision<\/strong>.<\/p> They allow: For this reason, they are widely used in: The limitation of an isolate is not its “quality,” In practice: may limit its use by the body.<\/p> Therefore, isolates are a concentrated form of a single substance – but their effectiveness depends largely on the form in which they are administered.<\/p> Technology is not the goal.<\/p> It responds to the biological limitations of how the body processes substances.<\/p> In practice, many active compounds: This means that even a well-chosen composition does not always translate into real action.<\/p> Liposomal and other lipid systems solve this problem by changing the physical form of the substance.<\/p> They work by, among other things: As a result, not only the quantity, but the kinetics of action<\/strong> change.<\/p> This means: In well-designed systems, one does not operate on assumptions, but on data.<\/p> The most common assessment is:<\/p> – particle size (e.g. DLS – dynamic light scattering), These are physical parameters to determine whether the formulation: Without this data, it is impossible to talk about the quality of the technology.<\/p> In practice, it’s not just one way.<\/p> It’s not about the choice: It’s about understanding the mechanism.<\/p> You can combine: These are not competing concepts.<\/p> These are the tools.<\/p> Their effectiveness depends on: It is not only what is in the product that matters.<\/p> The key is: Only a combination of: gives a realistic picture of the action.<\/p> It’s not a choice between one or the other.<\/p> This is to understand how the elements work together.<\/p> [1] Sercombe et al., Advances and challenges of liposome assisted drug delivery<\/em>, Frontiers in Pharmacology If you want to understand the topic in more depth, see what it looks like in practice: from nanoscale technology<\/a><\/strong>, through specific examples like liposomal curcumin<\/a><\/strong>, to the differences between liquid and powder forms<\/a><\/strong>.<\/p> If this topic is of interest to you – leave your email.<\/strong><\/p>Myth: “more = better”<\/h2>
