Does megadosing K2 work for adults? Regret not doing so in childhood

[GlamGuru]

I heard k2 is scarce in food compared to other nutrients, and people are often deficient in it without knowing.

many posts have said it makes face symmetrical, proper dental arch growth and proper frame bone growth. I wish i took this when i was a kid, megadosing now at 20+ feels pointless no?
