Understanding Bioavailability: Why Some Supplements Don't Work
Understanding Bioavailability: Why Some Supplements Don't Work
TL;DR: Bioavailability is how much of an ingested compound actually reaches target tissues. The gap between labeled dose and biologically active dose can be enormous — standard turmeric powder has roughly 1–3% bioavailability; standardized curcuminoid extract with piperine is dramatically higher. Earth Energy formulates around this: turmeric at 95% curcuminoids paired with piperine (Joint Support), colostrum in powder form to preserve heat-sensitive bioactives, and probiotic strains in Raw Reds to improve absorption of polyphenols.
You can take a supplement every day for months and see nothing. Switch to a different brand — same ingredient — and notice a difference within weeks.
That's bioavailability.
What bioavailability means
Bioavailability is the fraction of an ingested compound that actually enters circulation and reaches the target tissue. Everything is less than 100%. The gap between labeled dose and biologically active dose can be enormous.
Specific examples from Earth Energy's formulas
Turmeric in Joint Support: standardized to 95% curcuminoids — not plain turmeric powder, which has roughly 1–3% bioavailability. Standard turmeric passes through mostly unchanged. The standardized extract delivers significantly more active compound. Then it's paired with black pepper extract (piperine), which inhibits the enzymes that would otherwise degrade curcumin — substantially increasing absorption.
Boswellia in Joint Support: an extract with concentrated boswellic acids, not powdered resin diluted in inactive plant material. Bioavailable form of the active compound.
Raw Reds metabolic blend: includes piperine for the same reason as the Joint Support formula — to improve absorption of turmeric and other polyphenol-rich ingredients. The probiotic and prebiotic component is specifically designed to support the gut environment that makes everything else absorb properly.
Colostrum as powder: colostrum's immunoglobulins and growth factors are heat-sensitive. Earth Energy uses a powder format specifically to preserve bioactivity that processing into capsules or tablets would degrade.
Why form matters more than dose on a label
A label listing "magnesium — 400mg" tells you almost nothing useful. Magnesium oxide absorbs poorly and causes digestive upset. Magnesium glycinate absorbs cleanly and is far gentler. Same labeled mineral, completely different bioavailability.
Earth Energy's Transparency Promise addresses this directly: "We formulate around real research — if we can't include an ingredient at a dose that matches the science behind it, we leave it out."
Fat solubility and timing
Fat-soluble compounds — including many polyphenols and fat-soluble vitamins — absorb substantially better taken with food. Earth Energy's capsule-based products (Joint Support, Fruits & Veggies) are recommended with food for exactly this reason.
Frequently Asked Questions
What is bioavailability in supplements?
Bioavailability is the fraction of an ingested nutrient or compound that actually enters circulation and reaches the target tissue. A supplement can have a high labeled dose but poor bioavailability, meaning only a small percentage of what's on the label actually works in the body. Form, timing, co-ingestion, and gut health all affect bioavailability.
Why does turmeric powder have low bioavailability?
Standard turmeric powder has only 1–3% bioavailability because curcumin is rapidly metabolized and poorly absorbed in the gut. Standardized curcuminoid extracts paired with piperine (black pepper extract) substantially improve absorption by inhibiting the enzymes that degrade curcumin. Earth Energy Joint Support uses 300mg of 95% curcuminoid extract paired with black pepper extract for this reason.
How does piperine improve supplement absorption?
Piperine (from black pepper) inhibits certain gut and liver enzymes that metabolize and eliminate compounds before they reach circulation. This inhibition — called "first-pass metabolism inhibition" — significantly increases the bioavailability of curcumin, CoQ10, certain B vitamins, and other compounds. Earth Energy includes piperine in both Raw Reds and Joint Support.
Should fat-soluble supplements be taken with food?
Yes. Fat-soluble compounds including many polyphenols, vitamins A, D, E, K, and CoQ10 absorb significantly better when taken with a fat-containing meal. Earth Energy's Joint Support and Fruits and Veggies products are recommended to be taken with food for optimal absorption.
Why does Earth Energy use colostrum as a powder instead of capsules?
Colostrum's most important bioactive compounds — immunoglobulins and growth factors — are heat-sensitive proteins. High-pressure or high-heat processing during encapsulation degrades these bioactives. Earth Energy uses a powder format and advises against mixing with hot liquids to preserve the potency of what makes colostrum work. ---
