What is Kaempferia parviflora?
Kaempferia parviflora is found in the upper Northeastern regions of Thailand. Root extracts have a long history of use and a reputation for being a health tonic and energy enhancer (i.e., Thai ginseng). The novel active constituents are a special type of polyphenol called polymethoxyflavonoids. Sirtmax® Kaempferia parviflora root extract is standardized for polymethoxyflavonoid content.

Kaempferia parviflora Dosing Principles and Rationale
We consider Kaempferia parviflora to be in the adaptogenic herb category; following hormetic dosing principles (see Neurohacker Dosing Principles) with a high likelihood of having a hormetic range (i.e., a dosing range below and above which results could be poorer). We have selected to dose this at an amount that is within the studied range in humans.*
Kaempferia parviflora Key Mechanisms
Mitochondrial biogenesis
- Upregulates mitochondrial number[1]
- Upregulates Peroxisome Proliferator-Activated Receptor Gamma Coactivator-1alpha (PGC-1α)[1–3]
- Upregulates transcription factors for mitochondrial biogenesis (estrogen-related receptor-α [ERRα], nuclear respiratory factor-1 [Nrf-1], and mitochondrial transcription factor A [TFAM]) through activation of PGC-1α[2]
Mitochondrial function
- Upregulates AMP-Activated Protein Kinase (AMPK)[2,3]
- Promotes ATP production (output of mitochondrial oxidative phosphorylation)[3]
- Promotes mitochondrial β-oxidation (fatty acid metabolism) – upregulates peroxisome proliferator-activated receptor gamma (PPARγ) and delta (PPARδ)[2,4]
Exercise performance (ergogenic effects)
- Supports endurance performance[1,2,5,6]
- Supports post-exercise recovery[1]
- Supports muscle strength[5,6]
- Supports muscle metabolism (upregulates glycogen synthase and increases glycogen content)[1]
Metabolism
- Supports healthy insulin sensitivity[7]
- Promotes cell metabolism (muscle cell precursors [myoblasts] in vitro): promotes glucose uptake and the downregulation of lactic acid production; promotes the expression of glucose transporter 4 (GLUT4) and monocarboxylate transporter 1 (MCT1)[3]
Body weight
- Downregulates fat accumulation and blood/liver lipid levels[4,7,8]
- Promotes differentiation of brown adipocyte cells[4]
- Upregulates uncoupling protein 1 (UCP1) in brown adipose tissue - supports thermogenesis of brown adipose tissue [4,7,8]
- Promotes whole-body energy expenditure through activation of brown adipose tissue[7,9]
- Promotes lean body mass[2]
Antioxidant defenses
- Upregulates antioxidant enzymes (superoxide dismutase [SOD], catalase [CAT], glutathione peroxidase [GPx])[5]
Healthy aging and longevity
- Upregulates SIRT-1[2,10]
- Downregulates the production of advanced glycation end-products (AGEs)[10]
Cardiovascular function
- Promotes healthy nitric oxide (NO) signaling pathway function[11–14]
- Upregulates endothelial NO synthase (eNOS)[11]
- Inhibits phosphodiesterase 5 (PDE-5), the enzyme that cleaves the NO mediator cyclic guanosine monophosphate (cGMP) to 5’GMP[15]
- Positive effect on NO signaling pathway in cardiac tissue via upregulated cGMP levels[12]
- Promotes vasodilation via the NO signaling pathway[13,14]
Brain function
- Acetylcholinesterase inhibition (by the methoxyflavonoid 5,7-dimethoxyflavone [DMF])[16]
- Neuroprotection from glutamate excitotoxicity (by the methoxyflavonoid 5‐Hydroxy‐3,7,3′,4′‐tetramethoxyflavone)[17]
Reproductive function
- Inhibits phosphodiesterase-5 (PDE-5)15 and supports relaxation of the corpus cavernosum[18]
