Rauwolscine is a diastereoisomer (stereoisomer) of yohimbine with similar alpha-2 adrenergic antagonist activity. May be more potent than yohimbine at the same receptor. Used in fat burner supplements for 'stubborn fat' areas. Like yohimbine, works by blocking alpha-2 receptors that inhibit fat release. VERY LIMITED human research - potency and safety extrapolated from yohimbine data. Likely shares yohimbine's stimulant side effects (anxiety, elevated heart rate).

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 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.

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.

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 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.

OEA is an endogenous lipid signaling molecule produced in the intestines after fat consumption. Primary mechanism is PPARa activation (same receptor as fibrate drugs). Reliably reduces food intake in animal studies. Also activates GPR119 and TRPV1 receptors. Part of the endocannabinoid-like family but doesn't directly activate CB receptors. LIMITED human evidence - oral supplementation efficacy for weight loss unproven. Found naturally after olive oil consumption.

NAD+ is a critical coenzyme involved in cellular energy metabolism, DNA repair, and aging-related pathways. NAD+ levels decline with age, driving interest in supplementation for anti-aging. However, oral NAD+ itself has very poor bioavailability - PRECURSORS like NR (nicotinamide riboside) and NMN (nicotinamide mononucleotide) are generally preferred. NO GRADED OUTCOMES for direct NAD+ supplementation. Most NAD+ research actually uses precursors. Research on aging benefits is ongoing but preliminary.

New Zealand pine bark extract (Enzogenol) is derived from Pinus radiata, a different species than French maritime pine (Pycnogenol). Contains proanthocyanidins with antioxidant properties. Research has focused on traumatic brain injury recovery, blood sugar, and cognitive function. NO GRADED OUTCOMES - evidence is limited. Less researched than Pycnogenol but mechanistically similar. May have benefits for brain injury recovery.
