  73. Lion’s Mane

    3.5 /10 for metabolic health 7.2/10 overall Strong recommend Functional Mushroom

    A preliminary Taiwan pilot suggested HbA1c movement in prediabetes, but the result is not enough for a strong metabolic-health claim. Weight, glucose, and insulin endpoints need larger peer-reviewed trials.

  74. Urolithin A

    3.5 /10 for metabolic health 6.5/10 overall Worth trying Exogenous Metabolite

    Downstream mitochondrial signal only. Hodzic Kuerec 2024 found no clear anthropometric or broad metabolic outcome effect in humans.

  75. Cold Plunge

    3.5 /10 for metabolic health 6.3/10 overall Worth trying Cold Exposure

    Hanssen 2015 Nature Medicine showed 10 days of cold acclimation (14-15 degC, 2-6h/day) raised peripheral insulin sensitivity by approximately 43 percent in n=8 type 2 diabetes patients via skeletal-muscle GLUT4 translocation. Van…

  76. Pine Pollen

    3.5 /10 for metabolic health 5.7/10 overall Neutral Adaptogenic Herb

    Composition reviews note antidiabetic activity in animal models, but no human metabolic trial exists; the effect is preclinical only.

  77. 5-Amino-1MQ

    3.3 /10 for metabolic health 4.9/10 overall Neutral Research Compound

    Glucose tolerance normalized in obese mice, but mostly with related NNMT inhibitors such as JBSNF-000088 (Kannt 2018), not 5-Amino-1MQ itself.

  78. Thymosin Alpha-1

    3.0 /10 for metabolic health 7.3/10 overall Strong recommend Immune Peptide

    No direct metabolic-health evidence. A TESTS 2025 subgroup signal by diabetes was exploratory and does not establish glucose, insulin, or weight benefits.

  79. SS-31 (Elamipretide)

    3.0 /10 for metabolic health 6.0/10 overall Worth trying Mitochondrial & Longevity Peptide

    Mitochondrial function underlies metabolic health, but direct human metabolic endpoint data are limited and no diabetes or insulin-sensitivity RCT drives this report.

  80. Humanin

    3.0 /10 for metabolic health 5.5/10 overall Neutral Mitochondrial & Longevity Peptide

    Metabolic health is humanin's second-strongest mechanistic story, but it sits at a moderate score because the cleanest data came from rodents and a more potent analogue. Continuous central humanin infusion improved whole-body…

Questions about metabolic health

What scores highest for metabolic health?

Semaglutide, at 9.0 out of 10 for metabolic health. For metabolic-health, Semaglutide reaches 9.0/10 because Moiz 2024 found about 12.1 percentage points greater weight loss than placebo in non-diabetic obesity trials.

What is the cheapest thing that works for metabolic health?

Of the top-scoring options, Glycine is the least expensive at about $2 a month, scoring 6.5 out of 10 for metabolic health.

How many interventions has Outliyr scored for metabolic health?

80 of the 126 interventions evaluated for metabolic health score 3.0 out of 10 or better, which is the cut-off for appearing on this page.
