Sacred lotus

Sacred Lotus (Nelumbo nucifera) is an aquatic plant important in Asian cuisine and traditional medicine. All parts are used - seeds, leaves, rhizomes, flowers. Rich in polyphenols (catechins, procyanidins) and contains unique alkaloids like neferine. Preclinical research suggests anti-diabetic, anti-obesity, anti-depressant, and sedative effects. NO human clinical trials. Most interesting bioactive is neferine (unique to this plant) which shows various pharmacological effects in vitro. Remains underresearched in humans.

Detailed Outcomes

|
D
Blood Glucose Levels
In diabetic rodent models, lotus leaf extracts reduced blood glucose levels and improved insulin sensitivity. In vitro studies demonstrate alpha-glucosidase inhibition and AMPK pathway activation, suggesting a plausible mechanism, but no human clinical trials have been conducted.
5 studies
moderateImproves
D
Depressive Symptoms
In animal behavioral models (forced swim test, tail suspension test), lotus extracts showed antidepressant-like effects. Nuciferine, a key alkaloid, demonstrates dopamine receptor activity and may involve serotonergic pathways. No human studies exist.
2 studies
smallImproves
D
Sedation and Sleep Promotion
Neferine, a bisbenzylisoquinoline alkaloid unique to Sacred Lotus, has demonstrated sedative effects in animal models, possibly through calcium channel blocking activity. Doses used in preclinical studies are often unrealistically high relative to plausible human dosing.
2 studies

D
Lipid Profile
In animal models of diabetes and obesity, lotus leaf extracts improved lipid profiles including reductions in total cholesterol and triglycerides. Effects appear mediated through modulation of lipid metabolism and adipogenesis pathways. No human data available.
4 studies
moderateImproves
D
Body Weight and Adiposity
In rodent models, lotus leaf extract demonstrated anti-obesity effects by affecting lipid metabolism and inhibiting adipogenesis. Despite consumer interest in lotus leaf as a weight loss tea, no human clinical trials have been conducted to validate these effects.

D
Antioxidant Status
Sacred Lotus is rich in polyphenols including catechins and procyanidins. In vitro and animal studies demonstrate antioxidant capacity and reduction of oxidative stress markers. Relevance to human oral supplementation remains unestablished.

Related Supplements

Piperine

3 shared conditions · 9 outcomes

Piperine is the pungent alkaloid from black pepper (Piper nigrum). Primary use is as a bioavailability enhancer - increases absorption of many supplements (curcumin by 2000%, CoQ10, resveratrol, etc.) by inhibiting drug-metabolizing enzymes and transporters. IMPORTANT: Same mechanism that increases supplement absorption also affects medications - significant drug interaction potential. As a standalone supplement, has mild thermogenic and metabolic effects. BioPerine is a standardized 95% piperine extract.

Piceatannol

3 shared conditions · 8 outcomes

Piceatannol is a stilbene compound similar to resveratrol, found in passion fruit, grapes, and berries. Also a metabolite of resveratrol. May have superior bioavailability and bioactivity compared to resveratrol in some studies. Unique SIRT1 activation and AMPK effects. Preliminary human studies suggest benefits for insulin sensitivity. Less studied than resveratrol but potentially more promising. Contains extra hydroxyl group giving stronger antioxidant activity.

Mulberry Fruit Extract

3 shared conditions · 8 outcomes

Mulberry fruit extract is derived from the fruit of Morus alba (white mulberry). Different from mulberry LEAF extract (which is used for blood sugar control), the FRUIT extract contains anthocyanins and has been researched for glycemic control and antioxidant effects. NO GRADED OUTCOMES - research is limited. Contains cyanidin-3-glucoside and other anthocyanins similar to other dark berries. May have benefits for blood sugar and oxidative stress. Safe as a food; the fruit has been consumed for millennia.

Haskap Berry

3 shared conditions · 8 outcomes

Haskap berries (blue honeysuckle) are antioxidant-rich berries native to northern regions, called 'fruit of longevity' in Japan. Rich in anthocyanins (particularly cyanidin-3-glucoside), vitamin C, and polyphenols. NO GRADED OUTCOMES - limited human research. Anthocyanin content exceeds blueberries. May have cardiovascular, anti-inflammatory, and cognitive benefits based on similar berry research, but haskap-specific studies are lacking. Safe as a food. Available fresh, frozen, or as supplements. Emerging berry gaining research interest due to high polyphenol content.

Cyanidin

3 shared conditions · 10 outcomes

Cyanidin is a type of anthocyanin pigment found in dark berries, purple vegetables, and black rice. Cyanidin-3-glucoside (C3G) is the most studied form. Shows promise for blood glucose regulation, anti-inflammatory effects, and metabolic health. Notable for potentially improving glucose uptake without impairing muscle protein synthesis (unlike some AMPK activators). However, bioavailability is a major concern - most cyanidin is rapidly metabolized. Human evidence is limited despite promising in vitro data.

White Kidney Bean Extract

2 shared conditions · 6 outcomes

White Kidney Bean extract (Phase 2) is an alpha-amylase inhibitor that blocks starch digestion. It DOES work but potency is variable and modest - blocks ~25-65% of starch calories in acute studies. Meta-analyses show ~2kg weight loss over 4-12 weeks. Must be taken with starchy meals. Undigested starch goes to colon bacteria (gas, bloating). Better for preventing weight gain than losing existing weight. Works best with high-starch meals.

Valine

2 shared conditions · 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.

Tetraselmis Chuii

2 shared conditions · 7 outcomes

Tetraselmis chuii is a marine microalgae approved as a Novel Food in the EU. Rich in protein, omega-3 fatty acids, and antioxidants. Marketed as a sustainable superfood. NO GRADED OUTCOMES - human research is very limited. Primarily used in aquaculture as fish feed. Potential as a sustainable nutrient source but lacks clinical evidence for specific health claims. Generally safe as food.
