What is Longvida® Optimized Curcumin®

Longvida is a patented curcumin extract in a lipid matrix designed to deliver free (unconjugated) curcumin into circulation at practical daily amounts. Human and preclinical work spans recovery, inflammatory tone, cognition, and vascular function. Read more → Product profile sheet

How it works

Standard curcumin is hard to absorb and quickly inactivated. Longvida’s lipid system helps curcumin cross the gut wall and circulate as free curcumin. Human PK shows appearance in about an hour and detectable exposure across a 24-hour window—making an evening dose a good fit for overnight recovery, with support for antioxidant defenses and calmer day-to-day inflammatory signaling while you sleep. 

Benefits

• Supports healthy inflammatory responses after physical stress, with blunted rises in CK, TNF-α, and IL-8 versus placebo at 400 mg/day in a randomized trial. Read more → McFarlin 2016 (BBA Clinical)

• 
  Delivers free curcumin with markedly higher exposure than unformulated curcumin in human PK work, enabling practical once-daily use. 

• 
  Signals reported across mood/working memory and vascular endothelial function in human studies using typical daily amounts. Read more → Longvida presentation (clinical summary)

Dosage context

What RENEW provides: 400 mg Longvida® curcumin per day (per 2-capsule serving).

What research uses: Human studies with Longvida® commonly use ~400 mg/day (1×400 mg or 2×200 mg); some protocols use higher totals (up to ~1,000 mg/day) depending on outcomes and duration.

How this fits: 400 mg is a practical single daily dose chosen for meaningful biomarker and functional readouts. Take in the evening as part of RENEW so coverage aligns with sleep and nightly recovery.

Why this isn’t just turmeric

Turmeric is a spice with a small curcumin fraction, and standard curcumin is poorly absorbed. Longvida is engineered to deliver free curcumin with much higher exposure and sustained presence (onset ≈1 hour; detectable to 24 hours), which is why human trials at 400 mg/day show shifts in inflammatory markers and recovery measures.

FAQs (accordion)

What’s the difference between this and regular curcumin?

Standard curcumin is hard to absorb and is rapidly inactivated after you swallow it, so blood levels are often low and short-lived. Longvida uses a patented lipid matrix that delivers free (unconjugated) curcumin into circulation at practical doses. Human pharmacokinetic data show appearance in about an hour and detectable exposure across a 24-hour window, which is why 400 mg/day can deliver measurable effects in studies.

How quickly does it act, and why take it at night?
Free curcumin appears in about an hour and remains detectable across a 24-hour window in human PK work. An evening dose aligns coverage with your sleep period and RENEW’s overnight focus. Read more → Longvida presentation (onset ≈1 h); Product profile (24-hour note)
