What does it mean that health starts at the cell?

It means we look one layer underneath the organ or the symptom. Every organ is made of cells, and those cells share the same basic jobs — sensing signals, exchanging nutrients and waste, making energy, building tissue, maintaining themselves, and adapting. When we support those jobs with the right raw materials, the whole system tends to work more smoothly. It is a lens for understanding the body, not a replacement for your doctor.

What are deficiency and toxicity?

They are the two most common ways a cell gets into trouble. Deficiency is when a cell runs short on a raw material it needs, like a mineral, vitamin, or healthy fat. Toxicity is when a cell carries a burden it struggles to clear, like heavy metals or chronic excess. Both are things you can learn about and work on, and often they show up together.

Is The Holistic Hub a substitute for medical care?

No. Everything here is education about how the body works at the cellular level, built to sit alongside your relationship with your own provider, not replace it. We are careful to keep our claims qualitative and grounded, and we point to real sources so you can read further yourself.

Where should I start?

Cell 101 is the plainest on-ramp — it walks you through the whole model in one read. From there, the Start Here page lays out three simple first moves, one from each world (Cell, Mind, and Meaning), and the free tools let you put something into practice today at no cost.

Beta-sitosterol/plant sterols | Ingredient

See noteCell

Cortitrol's 110-165mg (depending on schedule) is roughly a tenth or less of the 1.5-3g/day range used for reliable LDL-lowering — this is a trace inclusion at these doses, not a cholesterol-management active. Structure/function only.

How it works

Exchange — structurally similar to cholesterol, competitively reducing intestinal cholesterol absorption at higher doses
Maintain — studied in athletes for post-exercise immune-marker support, a mechanistic/preclinical area of interest
Adapt — because Cortitrol's 110-165mg dose is far below the multi-gram range shown to affect cholesterol absorption, its inclusion here is better explained by the separate, lower-dose research on plant sterols and post-exertion immune-marker modulation than by any cholesterol mechanism
Exchange — structurally, beta-sitosterol differs from cholesterol only by one extra ethyl group on its side chain -- a small difference that is nonetheless enough for the body to absorb plant sterols far less efficiently than cholesterol itself, a built-in ceiling on how much circulates even with high intake

Form matters

The same nutrient can be made in very different forms — and a study done on one form does not automatically apply to another. Methylcobalamin is not cyanocobalamin; magnesium glycinate is not magnesium oxide; a whole-food extract is not the synthetic isolate that was studied. Two things decide whether what is in the bottle behaves like the research: the exact form, and independent lab verification (a Certificate of Analysis) that the form and dose on the label are truly what is inside. Without a COA, you are trusting a label, not the science.
