Fruits like oranges, bananas, avocados, and kiwis contain vitamin B, which is important for energy, brain function, and overall health. Other good sources include papaya, passion fruit, mangoes, and strawberries. Citrus fruits (like oranges) and avocados are particularly good sources of several types of B vitamins, such as B6 and folate (B9).
1st genetics
some ppl cannot process vit b3 b9 properly due to prenatal deficiency (their mothers were deficient while carrying them on their wombs and all previous gen will affect next gen)
2nd vit b from food are too little or non existent due to chem farming. i have grown veges n fruits using both organic n chems. organic produce SMELL TASTE DIFFERENT eg organic longan fragrance can be smelled from a few meters away, u go smell longans in supermarkets, no smell even put at nose level
B12 is almost non existent very scarce in nature as its produced exclusively by some microbes. vegetarian and diabetic (on Metformin) confirm need to supplement b12
deficient in 1 type vit b will affect all vit bs
3rd my own experience with mood anger, serious noise sensitivity. after vit b supplements, mood sleep better, mind chatter sounds better little negative thoughts wake up no groggy or moody, dont even flinch at loud bikes or children shrieking nearby
human bodies have capacity to produce own neurotransmitter for happiness emotional well being regulate sleep ie serotonin gaba melatonin etc but need sufficient vit bs nutrients

test yourself using b3 niacin red flush
