If you're talking strictly about energy production, a few of the following supplements might help:
Your multivitamin + C is a good start. I use the Orthocore multivitamin.
- ALCAR (acetyl L-carnitine) + other carnitine forms: In addition to being a nootropic (esp. when combined with R-ALA (the R enantiomer of Alpha Lipoic Acid)) Carnitine is used in Beta Fatty Acid oxidation, which directly produces Acyl CoA for use in the citric acid cycle (AKA krebs cycle = cellular respiration = energy production). Take carnitine separately from choline. Hopefully take some Fish oil (high in epa/dha) for some quality fats.
- CoQ10: used in Citric Acid Cycle (CAC)
- Additional B-vitamins (all of them): Used in Citric Acid cycle as necessary co-factors.
- other B-vitamins:
- Benfotiamine (form of B1 which in addition to AGE-fighting (Advanced Glycation End-products) properties, can boost TPP - thiamine pyrophosphate = required for CAC, and more specifically, is the prosthetic group in E1 enzyme of Pyruvate Dehyrogenase Complex (used to breakdown pyruvate into Acetyl CoA preceding CAC); TPP is also used directly in the CAC to clear Alpha-ketoglutarate)
- Sulbutiamine (form of B1 which promotes wakefulness/cognizance/alertness/reaction time/etc). Fat Soluble (other B-vitamins are water soluble and you'll just easily pass excess in urine). This is often seen as a nootropic AND an athletic supplement. Some people report negative effects.
- You could also experiment with dopaminergic supplements if you think you have a dopamine deficiency (N-acetyl Tyrosine, L-phenylalanine, etc) - low dose, slowly increase.
- Neurotransmitter imbalances get a bit complicated, and I wouldn't know what to recommend to be honest. I know that mild dopaminergics have a positive effect for me, as do Cholinergics.
- Amino Acid Supplementation: Some people are chronically deficient for one reason or another in BCAA's (Branched Chain Amino Acids: Leucine, Isoleucine, Valine) and EAA's (8 essential amino acids). I'd also add in Glutamine/Glycine. Amino Acid supplementation typically involves 15-30g taken throughout the day between meals + taken with B-vitamins (esp. B6 for BCAA's).
- Regular Exercise + proper nutrition + regular sleep: strength/resistance training + cardio on a regular basis. These steps are probably more important than all of the above. Watch the simple sugars: substitute complex carbs (whole grains/legumes/oats as opposed to white bread/sugars/soda) to prevent blood sugar spikes and hopefully improve insulin sensitivity in the long-term. Maybe you'll see less energy fluctuation.
Now then... noting the above, if you have a more serious health problem (which can be difficult to diagnose) - doing all of that probably won't help much. While the above supplements do help me a little, esp. the amino acids, I'm in that boat right now with a probable muscular/mitochondrial disorder (I'll be seeing a neurologist for an EMG + muscle biopsy as the next step).
