I wish I had learned about serums decades ago
One study, for instance, notes that people who are overweight or obese appear to have lower levels of vitamin B12 than those with a body mass index (BMI) that falls within the range considered to be normal. People who took vitamin B12 supplements of their own volition gained between 2.5 and 17 fewer pounds (1.27.7 kg) over ten years compared to those who did not take any form of supplementation with this vitamin

Epitalons appeal lies in its unusually broad mechanistic reach: it can activate telomerase and support telomere maintenance in human cells [12,13,14, 15], modulate gene expression epigenetically by influencing chromatin accessibility and promoter interactions [4], enhance tissue repair in disease contexts such as diabetic retinopathy by reducing oxidative stress and EMT while improving wound healing in retinal cells [16], bolster redox homeostasis by upregulating endogenous antioxidant defenses and lowering DNA-damage markers [1], rebalance immune tone via IL-2 upregulation [17] and shifts in CD4+/CD8+ profiles [18], and even reset circadian biology by tuning core clock genes and melatonin dynamics [19, 20]
People who get treated can focus better at work and feel more confident socially
A common example of this is B12 deficiency
