Hyperpnoea-Induced Bronchoconstriction (HIB)
HIB, also known as exercise-induced bronchoconstriction, is a closing or narrowing of the airways when someone breathes faster than normal (hyperpnea). HIB may be caused by a loss of heat or water from the airways or breathing in dry air during exercise or exertion.

Evidence-Based Protocol
Supplement stack ranked by research quality
Primary Stack (Tier 1)
May reduce exercise-induced bronchoconstriction severity; antioxidant that protects airways
Anti-inflammatory; may reduce airway inflammation and bronchoconstriction severity
Supporting Stack (Tier 2)
Mild bronchodilator; may reduce EIB severity when taken before exercise
Supports immune function; deficiency associated with worse asthma/EIB outcomes
Antioxidant; some studies show reduced EIB severity
Bronchodilator properties; supports smooth muscle relaxation
How It Works
Exercise-induced bronchoconstriction (EIB), also known as hyperpnea-induced bronchoconstriction, is a temporary narrowing of the airways that occurs during or after exercise. It affects about 10-15% of the general population and up to 90% of people with asthma.
WHAT HAPPENS:
During intense exercise, rapid breathing causes the airways to cool and dry out. This triggers inflammation and muscle spasm in the airways, making it harder to breathe.
SYMPTOMS:
TIMING:
TRIGGERS:
STANDARD TREATMENT:
EXERCISE MODIFICATIONS:
* Omega-3 fatty acids may reduce airway inflammation.
* Vitamin C taken before exercise may reduce EIB severity.
* Caffeine has mild bronchodilator effects.
Expected timeline: Supplements taken regularly may reduce EIB severity over weeks. Pre-exercise supplements (vitamin C, caffeine) work acutely.

Weight Loss & Maintenance

This goal refers to people with a BMI >25 attempting to reach/maintain their ideal weight. While interventions that work for people with a BMI >25 may also work for people with a lower BMI, the context is often sufficiently different that this isn't assured.
Type 2 Diabetes

Type 2 diabetes (T2D) is a disease in which blood glucose levels are too high. It is characterized by insulin resistance in muscle, fat, and pancreas cells and an inability of the pancreas to manufacture enough insulin to control blood glucose levels. T2D is strongly associated with excess body fat, and weight loss induced by lifestyle changes is extremely effective for treating T2D.
Type 1 Diabetes

Type 1 diabetes is an autoimmune disease in which the pancreas stops producing insulin. It can begin at any age, although most commonly in childhood or adolescence, and requires life-long treatment with insulin.

A stroke is a medical emergency. If you are experiencing stroke symptoms, call emergency medical services, even if they resolve quickly. This page does not discuss acute treatments for stroke, but rather focuses on mitigating the risk of having a stroke and supporting recovery from a stroke. Lifestyle and dietary habits that keep your blood pressure, blood sugar, cholesterol levels, and your weight in check, can help to reduce the risk of stroke.
