and the prolyl hydroxylase (PHD) family, which hydroxylates hypoxia-inducible factor (HIF) to mediate its degradation (Wu et al., 2018
Make sure youre getting adequate B2, magnesium, selenium, and vitamin C, either through diet or supplementation
The physiology is poorly understood, but may relate to changes in hypothalamic thermoregulation associated with fluctuations in estrogen levels
Typical dosing range: 100-250 mcg subcutaneously, 5 days on / 2 days off, often cycled 8 weeks on / 8 weeks off
Effective concentration 0.251 % w/w (optimal ~0.5% w/w) Clinical evidence Studies indicate that ethosomal encapsulation of retinol using TPGS modification substantially reduces degradation rates at room temperature while maintaining particle size stability
