Explore health conditions with evidence-graded supplement recommendations. Each condition page ranks ingredients by the strength of clinical research supporting them.

How We Grade Evidence

各症状ページでは、臨床エビデンスの強さに基づいてサプリメント成分をランク付けしています。各グレードの意味は以下の通りです：

Strong Evidence

Multiple randomized controlled trials (RCTs) or meta-analyses with consistent positive results and large sample sizes.

Good Evidence

At least one RCT with mostly consistent results across studies. Evidence suggests benefit but more research may be needed.

Some Evidence

Small studies or observational data with some positive signals. Promising but insufficient for strong recommendations.

Very Early Research

In vitro studies, case reports, or pilot studies only. Early-stage research that requires clinical validation.

Acute Bronchitis

5% of adults annually

Persistent cough (productive or dry) Chest discomfort Fatigue +3

Allergic Rhinitis

10-30% of adults globally; 40% of children

Sneezing Runny nose Nasal congestion +4

Gut Immune Health

Gut dysbiosis affects an estimated 25-45% of adults

Recurrent infections Bloating Irregular bowel movements +3

Post-Viral Fatigue

10-35% of individuals after certain viral infections; ~10% post-COVID

Persistent fatigue Brain fog Exercise intolerance +4

Chronic Inflammation

Estimated 50-60% of adults have at least one inflammatory biomarker elevation

Fatigue Joint stiffness Recurring infections +3

Recurrent Infections

~25% of primary care patients report recurrent infections

Frequent colds or flu Recurring sinusitis Repeated urinary tract infections +2

Oxidative Stress

Universal physiological process; pathological levels associated with chronic disease

Fatigue Frequent illness Poor wound healing +3

Stress-Related Immune Suppression

Chronic stress affects 70-80% of working adults

Increased illness frequency Slow wound healing Fatigue +2

Vaccine Response Support

Suboptimal vaccine responses in 30-50% of elderly adults

Reduced antibody titers post-vaccination Shorter duration of vaccine protection Breakthrough infections

Pediatric Immune Support

6-8 URTIs per year in children under 6

Frequent colds Ear infections Coughs +2

Exercise-Induced Immune Suppression

Affects endurance athletes and those in heavy training

Post-exercise URTIs Prolonged recovery Fatigue +1

Sinusitis

31 million episodes annually in the US

Facial pain/pressure Nasal congestion Thick nasal discharge +3

Wound Healing and Immune Recovery

50 million surgical procedures annually in the US require immune recovery support

Slow wound healing Post-surgical infection risk Delayed recovery +1

Skin Immune Barrier

Compromised skin barrier affects 15-20% of adults (eczema, dermatitis)

Recurrent skin infections Eczema flares Delayed wound healing +2

Upper Respiratory Tract Infections

2-4 episodes/year in adults; 6-8 in children

Nasal congestion Runny nose Sore throat +5

Influenza

5-15% of global population annually

High fever Body aches Chills +5

Immune Aging (Immunosenescence)

Affects all individuals with aging; clinically significant after age 65

Increased infection frequency Slower wound healing Reduced vaccine effectiveness +2

Autoimmune Conditions

5-8% of the population; >80 recognized autoimmune diseases

Varies by condition (fatigue, joint pain, skin rashes, digestive issues) Organ-specific symptoms Flare-remission cycles
