Supplements & Nootropics

Berberine may modestly improve blood sugar and lipids, but the evidence is short-term, mixed, and complicated by real drug-interaction risks.

Ashwagandha has some stress and sleep evidence, but liver, thyroid, pregnancy, medication, and product-quality cautions should shape any discussion.

Collagen peptides may modestly help joint pain, but product type, study quality, allergy risk, supplement safety, and realistic expectations matter.

Psyllium has evidence for constipation and modest LDL shifts, but it needs enough fluid, medication caution, and realistic expectations about benefits.

Collagen supplements may modestly affect skin hydration and elasticity, but the evidence is product-specific, industry-influenced, and far from the anti-ageing claims marketed online.

Vitamin D matters for bone and deficiency, but routine high-dose supplements are not a proven longevity strategy and can cause harm in excess.

Magnesium may help some poor sleepers, but trials are small and product-specific. Safety, kidney function, and medicine interactions still matter.

Berberine may modestly lower glucose in type 2 diabetes, but supplement quality, medicine interactions, and pregnancy risks keep the case cautious.

Creatine is more than a gym supplement, but cognition and longevity claims need careful reading. Here is what the evidence supports, and where it thins.
