1. Best Energy Supplements
So, which are the best energy supplements?
Let me share with you the most effective ones. Keep in mind they are listed in no particular order.
Ashwagandha is a herb used in traditional medicine known for being an adaptogen with many positive benefits. 
Among other benefits of supplementing it, Ashwagandha is known to be effective in increasing power output.
Two studies showed that supplementing 300-500 mg of Ashwagandha can increase power output in healthy individuals.
Another study on elite cyclists showed that those who were given this herb were able to cycle 7% longer.
Besides that, Ashwagandha is known to be able to enhance our body’s resilience to physical and mental stress.
Recommended daily dosage: 300-500 mg/day

2. Rhodiola Rosea
Rhodiola Rosea is another adaptogen herb that is known for its benefits for enhancing our ability to decrease stress. 
Besides, at least 8 studies found evidence that supplementing Rhodiola can enhance our physical performance.
Of course, all those studies show the link between Rhodiola and its ability to increase our energy, but this adaptogen herb also works as an anti-depressant, can improve our mood and our cognitive performance.
The best thing about Rhodiola Rosea is the fact that is considered safe and in general leaves no negative side effects.
Recommended daily dosage: 50 – 688 mg/day

3. Caffeine + L-Theanine
Caffeine is probably the most widely used stimulant and an energy-booster known for its positive effects on increasing our energy, focus, and attention.
Combined with L-Theanine, a popular amino acid, we can avoid the typical energy crash and nervousness that is usually the effect of overdosing with caffeine (which is quite common).
While caffeine ensures a quick energy boost, L-Theanine provides a relaxation effect without increasing drowsiness. 
Several studies actually show that the right combination of both nootropics can improve our reaction time, decrease tiredness and improve our memory.
Recommended daily dosage: 100 mg of caffeine with 200 mg of L-Theanine

4. Vitamin B12
Vitamin B12 is not a typical energy booster, but it can play a very important role in the process of transforming the food we eat in the energy.
Since most people are deficient in vitamin B12 nowadays (especially the riskier groups such as older adults, vegans, and people with GI disorders), ensuring a normal amount of B12 through supplementing is crucial.
While it is unknown how higher than recommended daily dosages of vitamin B12 influence our performance, it is still recommended supplementing it.
Vitamins B12 is considered a very safe vitamin, therefore there is nothing to worry about.
Recommended daily dosage: 10 mcg to 1g/day (it really depends from country to country); most experts recommend supplementing 250 mcg – 500 mcg/day
Coenzyme Q10 (CoQ10) is made naturally in all cells of our body. In addition, supplementing CoQ10 can provide a variety of benefits. 
CoQ10 is so interesting because our cells use it to make energy. Whenever our levels of Coenzyme Q10 decline, our cells cannot produce the energy anymore. The typical result of that is fatigue.
Supplementing CoQ10 has been shown as very effective, especially if people lack this coenzyme (which is often the case).
CoQ10 as a supplement comes in different forms – the most often used is ubiquinol.
Recommended daily dosage: 30 – 90 mg/day (up to 3 times per day)

PQQ (pyrroloquinoline quinone) is another interesting nootropic known to be an enzyme cofactor that has the ability to stimulate the production of new mitochondria. 
As you probably already know, the role of mitochondria in our body is to convert the food we eat into energy which consequently influences the performance of our cells.
Supplementing PQQ has been shown to be able to increase the number of mitochondria (hence, we have more energy which results in faster thinking and being more alert), but research also found that PQQ can help to increase the growth of neurons.
I was able to find out that PQQ works very well with Coenzyme Q10, so supplementing it together can provide a dramatic increase in mental and physical energy.
Recommended daily dosage: 2 – 40 mg/day

Ginseng (especially Panax Ginseng) is an adaptogenic herb known for several benefits including its ability to increase our energy, decrease stress, and boost our immune system. 
While current studies show mixed results on the effectiveness of Panax Ginseng on boosting our energy levels, we know that supplementing Ginseng can definitely reduce stress.
Recommended daily dosage: 200 – 400 mg (2 times/day)

We cannot talk about energy boosting supplements without mentioning creatine.
Creatine is one of the most popular and studied supplements. If there is one supplement that is considered extremely safe and provides multiple benefits, it is creatine.
This supplement is so interesting because it acts as a source of energy in our body.
To be more specific, creatine simply gives a phosphate group from its own molecular structure to an ADP molecule, making that compound ATP again.
The result is a lot of additional short-term energy that can be well used during an intense mental or physical activity.
Actually, a lot of athletes supplement creatine due to its positive effects.
Recommended daily dosage: 3-5 grams/day, taken in a longer period
Huperzine-A is another interesting supplement and a well-known nootropic that can mainly improve our mental energy and performance. 
This nootropic has become extremely popular in the past years and you can find it in some of the most effective nootropic stacks on the market.
But what role does it really play in our body?
Well, supplementing Huperzine-A can help to reduce distraction and tiredness while increasing our cognition.
Huperzine-A can provide several other benefits such as improved memory, alertness, and protection against Alzheimer’s disease.
Recommended daily dosage: 30 – 100 mcg/daily

10. Lion’s Mane Mushroom
When talking about powerful nootropics that can improve our mental energy and performance, we cannot miss Lion’s Mane mushroom.
This is one of the most powerful brain stimulants known to be a very effective natural energy booster that can combat fatigue, depression, and anxiety. 
One way that this effective nootropic can boost our mental energy is by activating NFG (neurotrophic growth factor).
Besides those benefits, supplementing Lion’s Mane has been shown to prevent neurodegeneration and help with inflammation.
That’s why a lot of popular energy supplements contain an extract of this mushroom.
Recommended daily dosage: 500 – 1000 mg (up to 3 times/daily)

Taurine is another natural stimulant that can improve mitochondrial function which consequently increases our energy.
While some experts believe that supplementing taurine can improve our capacity for exercise, the evidence for that is limited.
Taurine is often added to popular energy drinks, but it is not recommended to drink sugary drinks with this supplement.
While taurine is considered safe in the dosages up to 2 grams/day, many people report several side effects when taking it with energy drinks.
Recommended daily dosage: Up to 2 grams/day
12. Yerba Mate tea
Yerba mate tea is one of the popular South-American teas known to be great energy-booster and a very effective anti-oxidant. 
I prefer drinking yerba mate tea, while you can get in a supplement form as well.
Even though this tea contains quite some caffeine, it actually acts like green tea – it provides a smooth energy boost without the typical energy crash.
I often recommended drinking coffee in the morning and combining it with yerba mate tea in the afternoon.
Besides those benefits, yerba mate tea may be an effective antidepressant, it can improve your physical performance, it might improve your cognition, learning and also memory.
Recommended daily dosage: Drink 1-2 cups of yerba mate/day

Citrulline is an amino acid which is not a typical energy-boosting supplement, but it has a very special reason to be on this list.
Let me explain.
Citrullines’ main task is to increase nitric oxide in our body. And what’s the role of nitric oxide? Well, it increases circulation, which consequently allows oxygen, nutrients, and blood to travel across our body.
However, whenever we cannot produce enough nitric oxide, we may have a lack of energy.
So, supplementing citrulline can help us exercise longer and feeling less fatigue.
Citrulline is not a game-changer, but it can add a bit more energy and slightly improve our performance.
Recommended daily dosage: 6 – 8 grams/day (taken before physical activity)
Beetroot is a food that is often mentioned as an effective energy-booster.
How is that possible?
Well, taking beetroot can help us improve our workouts and athletic performance due to its ability to produce nitric oxide.
This food contains dietary nitrate (NO3), which provides nitric oxide molecules to the body to use.
While we don’t really understand how does the whole process work, we can easily measure the benefits of eating this food or supplementing it.
Recommended daily dosage: 300 – 600 mg/day
L-Tyrosine is an amino acid that is naturally produced by our body. It’s a very popular supplement among athletes due to its benefits on improving physical performance. 
Studies show that supplementing Tyrosine can increase our alertness, energy, and also restore memory.
Current studies also show that Tyrosine is extremely effective for people that lack it or people that work under severe stress (cognitive demanding tasks).
Therefore, it is recommended supplementing L-Tyrosine before working on a demanding task.
Recommended daily dosage: 500 – 2000 mg before an activity

ALCAR (Acetyl-L-Carnitine) is another amino acid that can improve our physical and mental performance. 
This amino acid is important for muscle energy function because long-chain fatty acids cannot cross mitochondrial membranes without it.
Besides, supplementing ALCAR is known to improve the production of acetylcholine, which can boost our alertness and memory.
As we can see, ALCAR seems to be a very potent amino acid that provides multiple benefits and can improve our mental and physical performance.
Recommended daily dosage: Up to 2 grams/day

17. R-Lipoic Acid
Last but not least, let’s talk about R-Lipoic Acid.
This is a compound that naturally occurs in our body. It is primarily known for its antioxidant benefits. 
But besides that, it may play an important role in our energy levels.
Why? Well, R-Lipoic Acid increases acetylcholine production, which improves our mental performance.
Besides, this supplement helps with regenerating other antioxidants in our body.
By reducing the inflammation, we should feel better and our energy should improve.
Recommended daily dosage: 300 – 600 mg/day
