Gluten

Gluten is a protein complex (gliadin + glutenin) in wheat, barley, and rye that gives dough its elasticity. MUST be strictly avoided by those with celiac disease (autoimmune). May cause symptoms in non-celiac gluten sensitivity (NCGS), though this is controversial and may overlap with FODMAP sensitivity. For healthy individuals WITHOUT celiac or NCGS, there is NO evidence that gluten-free diets provide health benefits - and they may reduce fiber and nutrient intake. Gluten-free mania is largely unwarranted for the general population.

Menthol

1 shared condition · 5 outcomes

Menthol is a cyclic monoterpene alcohol from peppermint and other mint oils that activates cold-sensing TRPM8 receptors, producing a cooling sensation. Used topically for pain relief (muscle aches, headaches) and in oral products. Interesting research for exercise in heat - menthol mouth rinse creates perception of cooling without actually lowering body temperature, potentially improving hot-weather performance. Also used in IBS (peppermint oil) for antispasmodic effects. Generally safe topically; internal use requires caution.

L-Carnitine

1 shared condition · 558 outcomes

L-carnitine can relieve leg pain in people with peripheral artery disease (PAD) and treat some aspects of metabolic syndrome. Although it’s often also used for fat loss, its effectiveness for that is questionable.
