Other bioavailable supplements are great for higher rates of
absorption efficiency such as: pyridoxal 5» phosphate (vitamin B6), riboflavin 5» - phosphate (vitamin B2), folinic acid and L -5-MTHF (active forms of folate), and adenosylcobalamin and methylcobalamin (Vitamin B12), and cholecalciferol (Vitamin D3).
Average particulate
mass absorption efficiencies for diesel trucks and light duty gasoline vehicles were 3.14 -LCB- + --RCB- 0.88 m -LCB- sup 2 -RCB- g -LCB- sub PM -RCB--LCB- sup -1 -RCB- and 2.9 -LCB- + --RCB- 1.07 m -LCB- sup 2 -RCB- g -LCB- sub PM -RCB--LCB- sup -1 -RCB-, respectively.
Halides, such as iodide or bromide, are mixed at different ratios to tune properties in the material, like band gaps, that determine
solar absorption efficiency.
Absorption efficiency of iron from of fortified grains is not any lower than absorption of naturally occurring iron in grains and in fact may even be a little higher.
