Lower blood pressure

What this outcome means

Thyroid-stimulating hormone, or TSH, is the pituitary signal used to gauge whether your thyroid is running fast, slow, or on track. On DoseRank it maps to a defined health outcome built from human studies on circulating TSH concentrations, reference-range positioning, and shifts in thyroid signaling — not a marketing claim.

Evidence level

79Moderate-strong

Sodium, Magnesium Glycinate, and Taurine – have strong public evidence, and Melatonin adds supporting evidence. DoseRank looks at both evidence quality and formula fit. A DoseFit Score of 77 means this product's ingredient forms and doses are close to what was used in the studies behind this ranking - DoseRank weights each product ingredient.

Sodium, Magnesium Glycinate, and Taurine lead this outcome, supported by Melatonin.

Dose matchedDoseFit 77

Scores reward products dosed inside or above the studied range, not just the right ingredient. Examples: In range: Magnesium Glycinate 300 mg vs 300-600 mg, Melatonin 5 mg vs 2-5 mg; Above range: GABA 500 mg vs 20-100 mg; Below range: Sodium 10 mg vs 1500-3000 mg, Taurine 300 mg vs 1000-6000 mg.

Thin spots

GABA has low evidence for this outcome, so it is flagged as an evidence gap rather than treated as a proven driver.

Plant-derived nitrogen compounds like caffeine that stimulate the nervous system. Effective but dose-sensitive, with real tolerance and dependence risk.

Essential micronutrients the body can't make in sufficient amounts. Fat-soluble ones (A, D, E, K) store up; water-soluble ones need regular topping-up.
