Does magnesium really improve sleep? We review randomized trials of magnesium glycinate, L-threonate, citrate and oxide, including sleep duration, time to fall asleep, subjective sleep quality and the role of magnesium deficiency.

GOS is one of the best-studied prebiotics; XOS is promising but less established. Here is how to read labels, judge claims, and avoid assuming that a GOS + XOS blend is automatically better.
Human studies do not support vitamin E as a reliable testosterone booster. One long-term trial found lower testosterone, while another found no change.
Perhaps, glucose is the most unique substance in the body. Glucose, as a simple sugar and the…
Proline and lysine are biologically important amino acids, but that does not mean isolated supplements automatically improve collagen, arteries, skin or muscle. The strongest human evidence is narrower.
CoQ10 is essential to mitochondrial energy transfer, but supplement benefits depend on the condition. Heart-failure data are promising but not definitive; statin-muscle evidence is mixed.
I found no convincing human evidence that NMN raises testosterone. A 12-week randomized trial measured testosterone directly and found no significant effect; my own repeated blood tests also showed no clear rise.
Vitamin K is a group of fat-soluble vitamins that the body needs for blood clotting, bone metabolism,…
Most vitamins and minerals do not need elaborate separation schedules. The interactions that matter most are a shorter list: calcium with iron, high-dose zinc with copper, biotin with lab tests, and vitamin K with warfarin.
Creatine transport systems can increase short-term creatine retention, especially with carbohydrate or protein plus carbohydrate. But do they improve strength or muscle growth beyond creatine monohydrate?
Let’s talk about an unsung hero in the bodybuilding universe – creatine, or in scientific terms, 2-(methylguanidino)…
Boron, a trace mineral found in certain foods and the environment, has been gaining attention for its…
NMN reliably raises NAD-related metabolites in human trials, but evidence that it slows human aging or extends lifespan is not established. This guide separates promising mechanisms from demonstrated clinical outcomes and summarizes current safety data.
My 25(OH)D rose only modestly while taking 5,000 IU/day, but that does not prove 10,000 IU/day is safe or beneficial. Current guidance sets a 4,000 IU/day adult upper intake level for unsupervised long-term use and does not support routine high-dose supplementation in healthy adults.
This will be a very short and compact article. So, fat burners, do they work and if…
Does resveratrol slow aging or explain the French paradox? Human trials show some modest metabolic effects, but no evidence that resveratrol extends human lifespan.
Dr. David Sinclair is an esteemed biologist and professor in the Department of Genetics at Harvard Medical…
Oral GABA has limited human evidence for stress and sleep, preliminary data for body composition, and small studies showing growth-hormone effects. My workout experience is anecdotal, not proof.
L-carnitine is essential for fatty-acid transport, but healthy adults make enough. Supplements may produce modest weight loss in some studies; exercise benefits are inconsistent and high doses can cause side effects.
