Comparison
Curcumin vs MOTS-c
Side-by-side of Curcumin and MOTS-c. Every row below is pulled from the compound schema and will update as our data grows. For deeper reads, follow through to each compound page.
Curcumin
Curcumin supplement guide: turmeric extract at 500-1000 mg/day, piperine and Meriva for absorption, evidence in joint inflammation and mood.
MOTS-c
MOTS-c peptide is a 16-amino-acid mitochondrial-derived peptide. Preclinical signals for insulin sensitivity, exercise capacity, dosage notes.
Effects at a glance
Curcumin
- •Reduces osteoarthritis knee pain comparable to ibuprofen at 1500 mg/day enhanced formulation
- •Modest antidepressant effect (SMD ~0.34) as monotherapy or SSRI adjunct in major depression
- •Standard curcumin has ~3% bioavailability; Meriva, BCM-95, Theracurmin shift absorption 5-30 fold
- •Inhibits NF-kB and COX-2; reduces hs-CRP, IL-6, TNF-alpha in chronic inflammation
- •Antiplatelet effect at higher doses; meaningful interaction with warfarin and DOACs
- •Iron chelation can contribute to deficiency in already-marginal patients
MOTS-c
- •16-amino-acid peptide encoded in mitochondrial DNA (12S rRNA region); discovered 2015
- •Activates AMPK in skeletal muscle and liver; improves insulin sensitivity in rodent models
- •Circulating endogenous levels decline with age, motivating the longevity-restoration hypothesis
- •CohBar's MOTS-c analog CB4211 discontinued after phase 1b NASH readout did not meet endpoints
- •Anecdotal protocols use 5 to 10 mg subcutaneously 2 to 3 times weekly
- •Not on the WADA Prohibited List as of 2026; future scrutiny likely given exercise-mimetic mechanism

Safety profile
Curcumin
Common side effects
- nausea
- diarrhea
- dyspepsia
- yellow stool (benign)
Contraindications
- active gallstones (curcumin stimulates gallbladder contraction)
- severe biliary obstruction
- scheduled elective surgery (discontinue 1-2 weeks prior)
Interactions
- warfarin and DOACs: additive antiplatelet and anticoagulant effects; meaningful bleeding risk at 1000+ mg/day(major)
- aspirin and NSAIDs: additive antiplatelet effect(moderate)
- tacrolimus and cyclosporine: CYP3A4 and P-gp modulation may alter drug levels(moderate)
- iron supplements: curcumin chelates iron; can contribute to deficiency in marginal patients(moderate)
- chemotherapy agents: potential interference with multiple agents; coordinate with oncology team(major)
MOTS-c
Common side effects
- injection-site irritation
- transient fatigue
- headache (anecdotal)
Contraindications
- pregnancy
- lactation
- active malignancy (theoretical)
- severe hypoglycemia risk on concurrent insulin or sulfonylurea
Interactions
- insulin: additive insulin sensitization may increase hypoglycemia risk(moderate)
- metformin: both activate AMPK; theoretical additive metabolic effect, no controlled data(minor)
- sulfonylureas: increased hypoglycemia risk via additive insulin sensitization(moderate)
Which Should You Take?
Curcumin comes out ahead for most readers on the criteria we weight: 3 catalogued goals, OTC dietary supplement, oral dosing, with a Tier-B outcome catalogued. MOTS-c is the right call when one of the conditionals below applies.
- → If your priority is post-training recovery, pick Curcumin.
- → If your priority is joint health, pick Curcumin.
- → If your priority is metabolic health and glucose control, pick MOTS-c.
- → If your priority is mitochondrial function, pick MOTS-c.
Edge case: If you want to avoid research-only / gray-market sourcing, Curcumin is the more accessible choice.
Default choice: Curcumin. Lower friction to source, and broader goal coverage. Reach for MOTS-c only if your priority sits squarely in the goals it owns above.

Common questions
What is the difference between Curcumin and MOTS-c?
Curcumin and MOTS-c differ in category (natural vs peptide), mechanism, and typical dosing. See the side-by-side table for full details.
Which has a longer half-life, Curcumin or MOTS-c?
Curcumin half-life is 7 hours; MOTS-c half-life is 0.5 hours.
Can you stack Curcumin with MOTS-c?
Stack compatibility depends on mechanism overlap, legal status, and individual response. Check each compound page for specific interactions and contraindications before combining.
