Lion’s Mane
Healthspan potential comes from multi-system coverage across cognition, mood, gut, immune, and nerve support. Human data remain too thin to treat Lion's Mane as a broad healthy-aging staple.
Read the Lion’s Mane report → -
Saffron
Healthspan support is plausible through mood, sleep, and vision preservation, but the clinical evidence is endpoint-specific and does not prove broad aging benefits.
Read the Saffron report → -
Coenzyme Q10 (CoQ10 / Ubiquinol)
The KiSel-10 cardiovascular mortality result and the benign safety profile make CoQ10 healthspan-relevant for older, at-risk adults, but it is not a broad healthspan intervention with direct endpoint data outside cardiovascular outcomes.
Read the Coenzyme Q10 (CoQ10 / Ubiquinol) report → -
Spirulina
The cluster of blood-pressure, lipid, and glucose improvements supports a modest healthspan case, but it rests on surrogate markers rather than functional aging endpoints.

Tongkat Ali
Healthspan support is indirect through stress, libido, mood, and androgen tone in older men. Evidence does not reach the standard of exercise, sleep, creatine, or cardiometabolic interventions.

Omega-3
Healthspan support is modest and context-dependent. Omega-3 can help inflammation, triglycerides, and mood in the right user, but does not act like a broad geroprotector.

Retatrutide
Metabolic disease improvement could extend healthspan in high-risk obesity, but retatrutide has no long-term morbidity, mortality, cancer, dementia, or frailty outcomes. Authority gaps keep this from becoming a broad healthspan recommendation.

Electrolytes
Hydration and mineral balance support multiple aging-related systems, especially in older adults with reduced thirst, but the effect is foundational rather than therapeutic.

Collagen Peptides
Collagen peptides may support healthspan indirectly through mobility, skin structure, glycine intake, and training tolerance. This cumulative case is reasonable but not disease-prevention evidence.

BPC-157
Broad tissue-protective effects support healthy aging in theory. No human healthspan trial exists, so this score reflects repair relevance in aging populations, not longevity proof.
Read the BPC-157 report → -
Phosphatidylserine
Cognitive aging is a core healthspan domain, and PS has targeted evidence in older adults with memory complaints. The rating stays moderate because guideline bodies remain cautious.
Read the Phosphatidylserine report → -
Thymosin Beta-4 (Tβ4)
Healthspan inherits the longevity gap. The anti-fibrotic, anti-inflammatory, and pro-angiogenic profile is consistent with healthspan-extending interventions, but no human aging or healthspan endpoint has been measured.

Semax
Cognitive preservation and stroke-recovery mechanisms are healthspan-relevant, especially in older adults, but the human evidence remains geographically narrow.
