Ingredients

L-tryptophan is an essential amino acid involved in protein synthesis, serotonin production, melatonin pathways, and normal metabolism. Research suggests it may modestly support sleep continuity at gram-level doses, but effects on mood and other outcomes remain preliminary. This guide explains the benefits, studied doses, safety concerns, medication interactions, and why Take Control Science uses a lower complementary dose.

L-theanine is a tea-derived amino acid studied for focused attention, stress support, and healthy sleep. This physician-reviewed guide explains what the research shows, where claims exceed the evidence, how much has been studied, and why Take Control Science uses 200 milligrams in Sleep Control.

Magnesium citrate is a well-absorbed form of magnesium that helps support normal energy metabolism, muscle and nerve function, glucose metabolism, blood pressure physiology, and bone health. This guide explains what the research actually shows, where the evidence is strongest, how dosage works, and why Take Control Science uses magnesium as part of a broader metabolic support strategy.

Creatine monohydrate is one of the most studied ingredients in performance nutrition, with strong evidence for supporting strength, power, repeated high-intensity exercise, and lean mass when paired with resistance training. This physician-minded guide explains how creatine works, how to dose it, what the research actually shows, who may benefit most, and where marketing claims go too far.
