MOTS-c is a mitochondrial-derived and exercise-induced peptide whose levels decrease with age [1]. It improves insulin sensitivity, glucose metabolism, and metabolic homeostasis [2]. Animal studies suggest that, by activating AMPK, it can mitigate obesity resulting from high-fat diets, aging, and menopause [3, 2]. It also regulates age-related inflammation and various aspects of age-related physical decline, such as bone and muscle losses [1].
In pancreatic cells, MOTS-c lowers insulin secretion and increases glucagon production [4]. In mice with aberrant lipid metabolism, MOTS-c treatment significantly reduced lipid buildup in liver cells [5].
In rodents, high-fat diet-induced obesity can promote insulin resistance and fat accumulation that triggers chronic inflammation. In mice, MOTS-c administration protects against both age-related and high-fat diet-induced insulin resistance, and diet-induced obesity [6].
Hormonal changes during pregnancy can affect insulin sensitivity and cause high blood sugar, leading to gestational diabetes. In pregnant women and mouse models of gestational diabetes, MOTS-c normalized blood sugar, and enhanced insulin sensitivity and glucose tolerance. The MOTS-c treatment lowered both the birth weight-associated complications and mortality of offspring caused by gestational diabetes [7].
Low estrogen during menopause can cause weight gain and fat redistribution in favor of white fats, which increases insulin resistance and the risk of metabolic disorders. In contrast, the more mitochondria-dense brown fats burn more calories, and improve glucose and lipid metabolisms. In ovarectomized mice, MOTS-c increases brown fat activation, and reduces fat accumulation and inflammation in white adipose tissue, which contributes to the lower level of fats in serum and liver [3].
In heart failure, fluid buildup and increased pressure in the lungs can cause lung injury. MOTS-c reduced heart dysfunction and remodeling caused by heart failure and lowered inflammation while boosting antioxidant activity in the hearts of sick mice [8]. It can also prolong injured heart and lung cells’ life cycle [9, 10].
Age-related sarcopenia can reduce overall healthspan and independence, while increasing various metabolic health risks. MOTS-c suppresses myostatin and lipid infiltration that contributes to muscle atrophy, even in immobilized animals [11, 12]. Older adults with higher circulating MOTS-c have better muscle performance and lean mass, while those with lower levels experienced more sarcopenia [13]. In a mouse model of aging, MOTS-c can significantly increase physical performance by activating genes related to skeletal muscle metabolism and myoblast adaptation to metabolic stress [1].
In an in vitro model of muscle development, MOTS-c peptide helps muscle cells to form properly, affecting their integral parts such as myotubes. It supports muscle cell formation at the expense of lipid accumulation while protecting muscle cells from the breakdown effects of inflammatory cytokine IL-6 [14].
Age-related bone loss often parallels muscle loss, and various anti-sacropenic stimuli also protect bone health. Importantly, metabolic dysfunction and inflammation tend to accelerate bone loss. MOTS-c mitigates age-related bone loss by stimulating osteoblasts and suppressing osteoclasts by modulating AMPK and inflammatory responses [15]. In a mouse bone damage model, MOTS-c treatment reduced bone loss and inflammation and prevented the formation of osteoclasts [16].
Sepsis is a potentially lethal condition characterized by systemic overactive immune reactions towards an infection or noninfectious agents. MOTS-c greatly improves survival and lowers bacterial counts in MRSA-infected experimental mice. It also reduces levels of pro-inflammatory cytokines like TNF-α, IL-6, and IL-1β, while increasing the anti-inflammatory cytokine IL-10 [17].
Type 1 diabetes patients have lower endogenous MOTS-c levels than healthy controls. In a mouse model of type 1 diabetes, exogenous MOTS-c prevents pancreatic β cell destruction by shifting CD4+ T cells towards a less self-destructive phenotype, suggesting that MOTS-c may be beneficial as an autoimmune treatment [18].
Age-related inflammation and declining antioxidant capacity are key drivers of aging and related diseases. Older adults aged 70–81 years have 20% less MOTS-c than younger adults 18–30 years old [19]. In a mouse model of type 2 diabetes, MOTS-c administration increased antioxidant enzymes like SOD and CAT, protecting myocardial cells from oxidative stress [20].
Unlike acute pain, neuropathic pain is pain caused by nervous system dysfunction related to nerve damages, rather than by injury or inflammation. MOTS-c’s antinociceptive effects pertain to its ability to restore mitochondrial health, and inhibit microglial and pain signals in the spinal cord [21]. Furthermore, compared to morphine, MOTS-c has far fewer side effects such as gastrointestinal transit inhibition and motor incoordination [22].
Every lot undergoes five independent assays before release. Results are published in the lot-specific Certificate of Analysis.
Every lot undergoes our 4-panel testing protocol: HPLC purity analysis, ESI-MS identity confirmation, LAL endotoxin screening, and amino acid analysis (for peptides >15 residues). Full analytical data is published in the Certificate of Analysis for each lot.
Lyophilized peptides should be stored at -20°C or below for long-term stability. Once reconstituted, peptides should be stored at 2–8°C and used within a reasonable timeframe depending on the specific compound. Avoid repeated freeze-thaw cycles. Always store in a dry environment away from direct light.
Orders placed before noon PST, Monday–Saturday, ship the same day. We offer free standard shipping on orders over $150. All orders are shipped in insulated packaging with ice packs when necessary. Standard delivery typically takes 2–4 business days within the continental US.
