In summary, our trial indicates a small protective effect of omega-3 treatment on slowing biological aging over 3 years across several clocks, with an additive protective effect of omega-3, vitamin D and exercise based on PhenoAge.
Up to 4 months slower aging over 3 years. Relatively large study over 777 participants.
What kind of supplements do you take, if any? Any studies to back up your choice?
  • Vitamin C (at least 100 mg) daily. Vitamin C is an important antioxidant. In contrast to most other vitamins it is water soluble and does not accumulate in the body. If saturation is reached the excess is excreted with urine. Read a mini review here: DOI: 10.1186/s12576-024-00922-7
  • Vitamin D (1000 IU) during winter.
  • Melatonin (0.5 mg) before sleep. Not because I can´t sleep but because this is another effective antioxidant. It also promotes the expression of some endogenous antioxidant enzymes. Read an overview here: DOI: 10.1007/s00018-017-2609-7

Only two with any regularity:
  • Vitamin D 5000 IU's, especially in the winter
  • Vitamin B12 1000 mcg, if I haven't been eating much fermented food
Everything else I try to get from diet.
