Dang Shen

Codonopsis pilosula (Dang Shen) is a Traditional Chinese Medicine herb historically used as an affordable substitute for Panax ginseng. Considered a 'qi tonic' for fatigue and weakness. Contains saponins, polysaccharides, and alkaloids. Limited research suggests possible immunomodulatory, neuroprotective, and anti-fatigue effects. However, evidence is almost entirely from animal and in vitro studies. Not equivalent to true ginseng despite historical substitution.

Detailed Outcomes

Immune Function

In vitro and animal studies suggest Codonopsis polysaccharides enhance immune cell function, including stimulation of macrophage activity and cytokine production. No controlled human trials have confirmed these effects.

small↑Improves

Cognitive Function

Animal studies suggest Codonopsis pilosula may enhance memory and exert neuroprotective effects, possibly through increased BDNF expression. Evidence is substantially weaker than for Panax ginseng, and no human trials exist for cognitive outcomes.

small↑Improves

Gastrointestinal Protection

In animal models, Codonopsis pilosula demonstrates gastroprotective effects, with polysaccharides providing mucilage-like protection to the GI lining. No human clinical data is available to confirm digestive health benefits.

Zeaxanthin

1 shared condition · 7 outcomes

Zeaxanthin is one of three macular carotenoids (with lutein and meso-zeaxanthin) that accumulate in the macula and protect against blue light and oxidative damage. AREDS2 formula includes 2mg zeaxanthin + 10mg lutein. Together they reduce AMD progression risk. Zeaxanthin is more concentrated in central macula than lutein. Found in orange peppers, corn, egg yolks. Generally used with lutein, not alone.

Yeast Mannan

1 shared condition · 4 outcomes

Yeast mannan (mannan-oligosaccharides/MOS) is a polysaccharide from yeast cell walls. Indigestible by humans but fermented by gut bacteria, acting as a prebiotic. Used primarily in animal nutrition to support gut health and immunity. NO GRADED OUTCOMES in humans - research is mostly in animals. May have immune-modulating effects. Part of yeast beta-glucan/MOS products. Generally safe.

Whole Coffee Fruit Extract

1 shared condition · 3 outcomes

Whole Coffee Fruit Extract (NeuroFactor brand) is marketed for increasing BDNF (brain-derived neurotrophic factor) levels. Made from the coffee cherry (fruit around the bean), NOT coffee beans. Contains polyphenols including chlorogenic acid. Little to no caffeine. One small study showed 143% BDNF increase with 100mg. Limited human evidence beyond BDNF marker. Claims exceed evidence - BDNF increase doesn't automatically translate to cognitive benefits.

Vitamin B12

1 shared condition · 18 outcomes

Vitamin B12 is an essential water-soluble vitamin that plays a role in neurological function and is important for DNA synthesis.

Valine

1 shared condition · 7 outcomes

Valine is one of three branched-chain amino acids (BCAAs), along with leucine and isoleucine. It's essential (must come from diet). NO GRADED OUTCOMES for isolated valine. Least studied and likely least important of the BCAAs for muscle building. Generally supplemented as part of BCAA mixture rather than alone. No unique proven benefits compared to other BCAAs. Safe as an amino acid. Adequate protein intake typically provides sufficient valine.

Sweet Flag

1 shared condition · 8 outcomes

Sweet flag (Acorus calamus) is a traditional herb used in Ayurveda and TCM for cognitive enhancement. DANGEROUS: Contains β-asarone, a KNOWN CARCINOGEN that causes intestinal tumors and organ damage in long-term studies. BANNED or restricted in many countries including the US (not allowed in food). NOT RECOMMENDED for supplementation due to cancer risk. Despite traditional use, the toxicity profile makes this herb unsuitable for modern use.
