As peptides in solution are generally less stable than lyophilized peptides, many researchers keep peptides in their lyophilized form until they need them for a specific study
Coenzyme Q10 is a critical component of mitochondrial respiration and the reduced form (ubiquinol) plays a key role as an antioxidant, by neutralising free radicals, and first line defence against oxidative stress induced damage, within the mitochondria

Key Takeaways Egg quality declines with age primarily due to mitochondrial dysfunction and oxidative stress, increasing chromosomal abnormality rates from ~20% in your early 20s to over 80% by age 43 The 90-day egg quality window reflects the ~90 days it takes for a primordial follicle to mature into an ovulatory egg, lifestyle and supplement changes need this time to take effect CoQ10 (400-600 mg/day) is the most-studied supplement for egg quality, with evidence showing improved mitochondrial function, oocyte quality, and IVF outcomes Antioxidants including vitamin E, melatonin, and NAC may reduce oxidative damage to developing eggs, though human trial data remains limited for some A Mediterranean-style diet rich in omega-3 fatty acids, folate, and antioxidants can support better fertility outcomes in multiple observational studies Environmental toxins including BPA, phthalates, and cigarette smoke directly damage oocytes, reducing exposure is a modifiable factor within your control What Is Egg Quality and Why Does It Matter for Fertility
