28 Trials on Cinnamon: Mixed Blood Sugar Results in Diabetes

Image
Cinnamon has lowered blood glucose modestly in some studies, but the results are inconsistent and it is not a proven treatment. A 2024 review of 28 trials found a pooled fasting glucose drop of about 15 mg/dL, yet its authors cautioned against firm conclusions. Cinnamon is no substitute for the care your clinician prescribes, so talk with your care team before trying any supplement. TL;DR: Long term control changed little: a 2023 umbrella analysis found an HbA1c reduction of about 0.10 percentage points, while trial results varied widely. Trials used 0.5 to 6 g daily, but species and preparation varied, so no standard dose exists for over the counter supplements. Choose clearly labeled Ceylon and third party tested products, because Cassia contains more coumarin and FDA alerts have flagged lead in some ground cinnamon. If you take insulin or drugs that lower glucose, consult your clinician first and agree on closer monitoring, a trial period, and stopping criteria. Celluvive Explore We...

Creatine HCl vs Monohydrate: Pay for Creatine Not the Label

Image
For almost everyone, creatine monohydrate is the smarter default: decades of research back it, and it costs less per effective gram. Creatine HCl is worth considering only if you get persistent stomach upset from a verified high-purity monohydrate. Either way, what matters most is matching the actual creatine content and choosing a tested product, not the form on the label. TL;DR: A randomized trial that lasted eight weeks found no strength or body composition advantage for HCl, although its small sample limits firm conclusions. Match actual creatine content, not powder weight: aim for 3 to 5 grams daily, and check the label because no universal HCl conversion exists. Loading around 20 grams daily for up to seven days speeds muscle saturation, but splitting doses or starting with maintenance dosing may reduce stomach complaints. HCl dissolves more readily and mixes with less grit, but human trials have not shown that faster dissolution improves muscle loading or performance. People tak...

Genetic Testing: Check U.S. Insurance Coverage Before the Sample

Image
Insurance typically covers genetic testing when a licensed clinician orders it as medically necessary or clinically useful for an active diagnosis, treatment decision, or documented family risk. Screening tests and most direct-to-consumer kits are usually excluded. The Genetic Information Nondiscrimination Act protects you from health insurance discrimination based on genetic results, but it never requires an insurer to pay for testing. Your first move: confirm the test name and CPT codes with your provider, then request prior authorization before any sample is collected. TL;DR: Payers look for symptoms or documented family risk, evidence supporting the test, and a clear explanation of how results change treatment or monitoring. Medicare contractors can apply different local rules, Medicaid coverage varies by state, and employer plans may differ even when the same insurer administers them. Before collection, obtain the performing lab’s exact test name and CPT or HCPCS code, then h...

NAC vs Glutathione: Why NAC Usually Comes First

Image
For most people, NAC is the smarter place to start because it reliably raises intracellular glutathione and carries a much larger body of clinical evidence than standalone glutathione products. Direct glutathione formulations, especially sublingual or liposomal versions, deserve a closer look when synthesis is impaired or when faster repletion matters. If you take blood thinners or nitrate medications, talk with your clinician before adding either one. TL;DR: Standard oral glutathione breaks down during digestion; a trial lasting three weeks favored sublingual delivery, while micellar forms yielded 2.4 to 2.5 times greater exposure. A pilot lasting 24 weeks found GlyNAC corrected glutathione deficiency in older adults and improved oxidative stress, mitochondrial function, cognition, and strength. Published oral NAC trials commonly use 600 to 1,800 milligrams daily, while liposomal glutathione trials use 250 to 500 milligrams; IV treatment requires clinical supervision. NAC’s stron...
