Vitamin A is pretty scarce in many diets, yet a 2010 paper shows that sufficient vitamin A produces 30% increase in ATP production. [0] ATP facilitates energy transfer between cells [5]
Lots of sources including wikipedia vitamin A page [6] don't seem to recognize the role of Vitamin A in energy transfer between cells. [2] [4] Wikipedia page for ATP does not mention the link with Vitamin A either. [7]
There are reports of Vitamin A supplements producing psychological productivity energy boost akin to caffeine. [1]
One cup of boiled carrots is sufficient daily intake of vitamin A. [2] Boiling the carrots increases vitamin A absorption due to breaking down the cellulose in carrots. [2]
Other sources include cooked tuna, cooked squash or pumpkin, cooked sweet potato, cooked spinach/kale/collard/chard/bok choy, or beef/fish liver. [3] If you aren't eating a good amount of these foods every day you are likely deficient.

Supposedly many people are deficient in magnesium.
Another thing I've heard is that you need vitamin K to process vitamin D supplements. Yet many people have lower levels of vitamin K so the vitamin D supplements are less effective.
I've also heard that Omega supplements are better from non-fish bases because the fish oil tends to rapidly oxidize.
NAC could protect your liver and kidneys when drinking alcohol (or other toxins -they give an IV version to acetaminophen OD patients). It works by increasing intracellular gluthiomine levels.
Supplements are loosely regulated so it's important to pay attention to brand reputation, testing, and certifications.
Most people don't need supplements if they would just eat a healthy diet.
