Lutein- Your screen emits the exact wavelength that it absorbs
<p>Blue light (peak ~440nm) from screens and LEDs falls within the absorption spectrum of macular pigment (lutein + zeaxanthin, peak absorption 460nm). </p><p>Macular pigment literally filters the specific wavelength your screen emits most. </p><p>The "blue light protection" positioning for lutein isn't marketing spin, it's physics.</p><p><br></p><p><strong>Publications of interest:</strong></p><p>https://pmc.ncbi.nlm.nih.gov/articles/PMC11933726/, https://pubmed.ncbi.nlm.nih.gov/22465791/, https://pmc.ncbi.nlm.nih.gov/articles/PMC4698938/</p>

Cranberry- A-type vs. B-type proanthocyanidins: the same molecule class, different linkage, completely different function
<p>Cranberry has A-type PACs (anti-adhesion); grape seed has B-type PACs (antioxidant/vascular). </p><p>The only structural difference is one additional ether bond between flavanol units. </p><p>That single bond changes the entire biological function. </p><p>Most consumers and many companies don't know there are two types, let alone that they do completely different things.</p><p><br></p><p><strong>Publications of interest:</strong></p><p>https://pmc.ncbi.nlm.nih.gov/articles/PMC10215713/, https://pmc.ncbi.nlm.nih.gov/articles/PMC3823508/, https://pmc.ncbi.nlm.nih.gov/articles/PMC8389005/</p>

Bergamot- The ingredient that proves terroir isn't just for wine
<p>Bergamot polyphenols only reach therapeutic concentrations in fruit grown in Calabria's specific microclimate (Reggio Calabria). </p><p>Attempts to cultivate bergamot in other regions produce fruit with significantly lower brutieridin/melitidin content. </p><p>The bioactive profile is literally tied to geography making single-origin bergamot a genuine terroir story comparable to Champagne or Parmigiano-Reggiano.</p><p><br></p><p><strong>Publications of interest:</strong></p><p>https://pmc.ncbi.nlm.nih.gov/articles/PMC8569986/, https://pmc.ncbi.nlm.nih.gov/articles/PMC11241439/, https://pmc.ncbi.nlm.nih.gov/articles/PMC4345801/</p>
