Feb 24, 2026Menopause and Perimenopause: Supplement Evidence for Hot Flashes, Bone Loss, and Cognitive SymptomsThe menopausal transition accelerates bone loss, cognitive change, sleep disruption, and cardiovascular risk. Supplement evidence varies sharply: isoflavones have modest hot flash data; calcium and vitamin D are well-supported for bone; magnesium helps sleep. Black cohosh is used widely but evidence is mixed.
Feb 20, 2026Creatine for Aging: Muscle Preservation, Cognitive Benefits, and Monohydrate vs AlternativesCreatine monohydrate is one of the most evidence-backed supplements for older adults, improving muscle strength, power output, and lean mass when combined with resistance training. Emerging evidence supports cognitive benefits — particularly working memory and processing speed. Monohydrate remains superior to proprietary alternatives.
Feb 19, 2026Vitamin B12: Deficiency in Aging, Neurological Consequences, and Supplement Form EvidenceB12 deficiency affects 10–30% of adults over 50, largely due to reduced gastric acid and intrinsic factor. Deficiency causes irreversible neurological damage if uncorrected. Methylcobalamin and adenosylcobalamin are preferred over cyanocobalamin for neurological applications. High-dose oral B12 can bypass intrinsic factor.
Jan 29, 2026Magnesium L-Threonate and Brain Aging: Synaptic Plasticity, Magtein Evidence, and AnxietyMagnesium L-threonate was developed specifically to raise brain magnesium levels. Animal data show impressive synaptic plasticity and memory improvements. Human trials are fewer but suggest cognitive benefits and anxiety reduction in older adults.
Jan 28, 2026LionLion's mane (Hericium erinaceus) contains hericenones and erinacines that stimulate nerve growth factor (NGF) synthesis. Human trials show improvements in mild cognitive impairment, though optimal extract form and dose are still being established.
Jan 27, 2026Alpha-GPC: Bioavailable Choline, Cognitive Aging, and Acetylcholine SupportAlpha-GPC is the most bioavailable choline supplement and crosses the blood-brain barrier effectively. Clinical trials show improvements in cognitive function in older adults with mild cognitive impairment. Often preferred over citicoline for acute cognitive enhancement.
Jan 26, 2026PQQ (Pyrroloquinoline Quinone): Mitochondrial Biogenesis, NGF Upregulation, and Evidence QualityPQQ stimulates mitochondrial biogenesis via PGC-1alpha and upregulates nerve growth factor (NGF). Human trial evidence is limited but suggests improvements in cognitive function and sleep quality. Often stacked with CoQ10.
Jan 25, 2026Acetyl-L-Carnitine (ALCAR) and Brain Aging: Evidence, Mechanism, and Nerve HealthAcetyl-L-carnitine (ALCAR) crosses the blood-brain barrier and supports acetylcholine synthesis and mitochondrial function in neurons. Evidence supports mild cognitive decline and peripheral neuropathy. ALCAR differs importantly from L-carnitine in CNS access.
Jan 24, 2026Citicoline (CDP-Choline): Acetylcholine Synthesis, Brain Energy, and Stroke RecoveryCiticoline provides both choline (for acetylcholine) and cytidine (converted to uridine, a phosphatidylcholine precursor). Evidence supports cognitive protection after stroke and modest improvements in age-related cognitive decline.
Jan 23, 2026Bacopa Monnieri and Memory: Bacosides, Cognitive Aging, and 12-Week RCT EvidenceBacopa monnieri improves memory consolidation and information processing in older adults. Consistent effects require 8-12 weeks of daily use. Bacosides A and B are the primary active compounds. GI side effects occur at higher doses.
Jan 13, 2026Phosphatidylserine for Cognitive Aging: Memory Decline, Evidence Grade, and PS+DHA SynergyPhosphatidylserine has FDA-qualified health claim status for cognitive aging. Older trials with bovine-derived PS showed consistent memory benefits; soy-derived PS effects are smaller but still meaningful.
