YOU SAID:
My head hurts because of my body lacking d-vitamines
INTO JAPANESE
体にd-ビタミンが不足しているため頭が痛い
BACK INTO ENGLISH
My head hurts because my body is deficient in d-vitamins
INTO JAPANESE
体にd-ビタミンが不足しているので頭が痛い
BACK INTO ENGLISH
My head hurts because my body is deficient in d-vitamins
That didn't even make that much sense in English.
