Best Nootropics for Depression

Nootropic forums and blogs often describe depression as a neurotransmitter imbalance in the brain. And then offer suggestions on various nootropics to help lift mood and banish depression.

But this simplistic view of depression misses the complexity of this disease. Recent research has shown that depression can have many possible causes. Including out of whack mood regulation by the brain, genetic problems, stressful events, prescription medications and medical problems.

It’s true that neurotransmitters are involved in the process that contributes to depression. But it’s usually not a matter of one neurotransmitter being too low and another too high.

Instead, you have several neurotransmitters, amino acids, hormones and other neurochemicals working both inside and outside neurons.

The interaction of these neurochemical reactions make up a highly dynamic system that is responsible for your mood. And how you perceive and experience life.

With this level of complexity, you may have similar symptoms of depression to the person next to you. But the issues in your brain and body may be completely different. So what works best for someone else experiencing your symptoms may not be best for you.

And this is why we often say in the nootropic community that Your Mileage May Vary (YMMV) when describing a particular nootropic supplement. And how it feels.

Depression and Neurogenesis

It turns out that neuron connections, neurogenesis and the function of neuronal circuits may play a more important role in depression than levels of neurotransmitters.

For example, researchers in Munich studied 24 women who had a history of depression. And on average, the hippocampus was 9 – 13% smaller in depressed women compared to healthy women. And the more bouts of depression a woman had, the smaller the hippocampus.[i]

We know that stress plays a role in depression. And research has shown that stress can suppress neurogenesis. Which would account for the smaller hippocampus in these women.

We also know that Brain-Derived Neurotrophic Factor (BDNF), a naturally occurring protein, is critical for preventing apoptosis (brain cell death), growth of new neurons (neurogenesis) and growth of synapses.

Please check out this article on “13 Nootropics to Boost BDNF”. Increasing BDNF is one way to combat depression. And you’ll see some parallel between the nootropics listed below. And the list of nootropics used for boosting BDNF.

If you’ve ever tried antidepressants, you know that it often takes weeks to feel any benefit. Scientists have a theory that the value of these medications may be in generating new neurons (neurogenesis), strengthening neuron connections, and improving neural signaling.

So now researchers speculate that new medications could be developed that specifically promote neurogenesis. As it turns out, we already have this ability with several natural nootropic supplements.

Depression and Neurotransmitters

Now that we know that neurotransmitters are not the only critical part of preventing depression. We can’t discount their importance either.

Neurons are specifically designed to communicate with each other. When a neuron is activated, it passes an ‘action potential’ down its axon to the axon terminal. Neurotransmitters are stored in vesicles in this terminal.

The action potential (signal) releases certain neurotransmitters into the synapse (space between neurons). And on to the dendrite of the receiving neuron. As the concentration of neurotransmitters rise in the synapse, they bind to receptors embedded in the membranes of the two neurons.

This release of a neurotransmitter from one neuron can activate or inhibit the second neuron. Once the first neuron has released a certain amount of neurotransmitter, a feedback mechanism instructs the neuron to stop putting out this neurotransmitter and begin bringing it back into the 1^st neuron. This process is called reuptake.

In those who are severely depressed or manic, this fine-tuned system of neuro-signaling goes out of whack. Either too much or too little of the neurotransmitter is released.

Or if the reuptake is overly efficient and mops up too many neurotransmitter molecules before they have a chance to bind to receptors. It can have a significant impact on mood.

The primary neurotransmitters that play a role in depression include:

• Acetylcholine
• Dopamine
• Glutamate
• GABA
• Norepinephrine
• Serotonin

Each one of these neurotransmitters can be boosted, or their reuptake affected by nootropic supplements (listed below).

Depression and Prescription Medication

Depression is often a side effect of certain prescription drugs. These drugs include; antimicrobials, antibiotics, antifungals, antivirals, heart and blood pressure drugs, hormones, insomnia drugs, tranquilizers, antacids, narcotic pain drugs and more.

We know from experience that many of these prescription drugs can be replaced by safer, natural alternatives. Like nootropic supplements.

But I am NOT encouraging you to stop using whatever meds you’re currently on. Without consulting with your doctor first. I am encouraging you to seek out safer alternatives that often do the job just as well.

Depression and Stress

Nearly all of us experience stressful events. And while not everyone of us who faces stress develops depressive disorder. Stress does play an important role in depression.

Depending on how sensitive you are to stress, along with messed up neurochemistry and even genetics. A perfect storm of any or all of these influencing factors can lead to depression.

So please check out my extended article on “Best Nootropics for Anxiety” which includes several nootropic supplements that help you deal with and conquer stress.

Recommended Nootropics for Depression

If you are currently being treated for depression. Or suspect you may be dealing with undiagnosed depression. And are looking for a more natural, safer way to treat your symptoms. Nootropics could be the answer.

You’re not alone looking for an alternative to drugs that come with a host of side effects. Research in the United States and other countries show that significant numbers of people use ‘alternative medicine’ to treat their depression.

Researchers conducted a survey of more than 3,000 women in the USA to find out how many turned to alternative medicine for depression. Of the 220 women who said  they had been officially diagnosed with depression, 54% said they used alternative medicine to treat their symptoms.[ii]

We have found that the following list of nootropics work well for different types and causes of depression.

As I mentioned before, your mileage may vary. What works for me may not work for you. Wise and careful experimentation is critical to finding a safer alternative for treating your depression.

1. Aniracetam – A member of the racetam-family of nootropics, Aniracetam works with dopamine D₂ and D₃ receptors in your brain. And desensitizes AMPA (glutamate) receptors.

   Aniracetam is one of the most effective antidepressants I’ve even tried. And its effects on dopamine in your brain can have a profound effect on anxiety symptoms as well.

2. Bacopa Monnieri – One of the most powerful herbs in Ayurvedic healing. Bacopa has been used for millennia to relieve anxiety, fatigue, restore energy and boost concentration.

   This adaptogen has been shown in clinical studies to work as well for depression as benzodiazepines and tricyclic antidepressants.[iii]

3. Coenzyme Q10 (CoQ10) – CoQ10 is your cell’s natural source of energy. Fueling your mitochondria by taking fat and converting it into usable energy. CoQ10 preserves brain function, helps fight mental illness and migraines.

   Major depression, bipolar disorder and schizophrenia are now being recognized as having mitochondrial dysfunction in common. With higher oxidative stress levels.[iv] Studies show that 1,200 mg per day of CoQ10 in bipolar adults experienced a significant reduction in depression.[v]

4. 5-HTP – I do NOT recommend using 5-HTP for treating depression. But thought to include it here since it is promoted as a “natural antidepressant”.

   This amino acid is naturally produced in your body. And synthesized from the amino acid tryptophan which we get from food. 5-HTP is the precursor needed to produce the ‘feel-good’ neurotransmitter serotonin. But a summary published by the Alternative Medicine Review noted a lack of evidence for ‘loading’ precursors to treat depression.[vi] Combining 5-HTP with SSRI’s, Tricyclics or MAOI’s will cause Serotonin Syndrome. And the side effects on its own are nasty. Or even deadly.

5. Ginkgo Biloba – This tree native to China has been used for thousands of years to boost mental alertness, improve cerebral circulation and for overall brain function. Many have found Ginkgo to be very effective in reducing anxiety and stress. And for boosting mood.

   1,570 men and women in England participated in a study using 120 mg of Ginkgo Biloba extract daily for 4, 6, and 10 months. Those who used Gingko the longest experienced the most improvement in ratings for anxiety, depression, energy, drowsiness, sadness and happiness.[vii]

6. Iodine – Did you know that iodine deficient populations are up to 13.5 IQ points less than normal people?[viii] Since iodine has largely been removed from table salt in some countries, it has been suggested that iodine deficiency is epidemic. Particularly in countries like the United States.

   Iodine is essential to thyroid health. And nearly every tissue in your body relies on thyroid hormones. Not enough iodine can result in hypothyroidism. Negatively affecting acetylcholine synthesis in your brain. Affecting cognition, memory, learning, recall and mood.

7. Kava – Kava is native to the South Pacific. And the islanders use kava for its sedative effects. Kava can help reduce anxiety and depression. Unlike benzodiazepines, kava does not impair cognitive function. In fact, studies show that not only will it improve mood. But may boost cognitive function as well.[ix]
   
8. Lion’s Mane Mushroom – Also called the “smart mushroom”, Lion’s Mane boosts brain nerve growth factor which increases neurogenesis. Lion’s Mane can help improve focus and attention, boost thinking, repair brain cells, and help anxiety and depression.

   Women in Japan received Lion’s Mane-laced cookies for 4 weeks during a clinical trial. The researchers found that Lion’s Mane reduced anxiety and depression in these women during the trial.[x]

9. Magnesium – Lack of adequate magnesium can result in brain fog, anxiety and depression. Plasticity of neuron synapses is affected by the presence of adequate magnesium in brain cells.

   A study was conducted with 5,708 people in Norway. The aim of the study was to examine the association between magnesium intake and depression and anxiety. The researchers found that low magnesium intake is related to depression.[xi]

10. Mucuna Pruriens (L-DOPA) – L-DOPA is synthesized from the amino acid tyrosine in your body. And is a precursor to the formation of dopamine, epinephrine and norepinephrine in your brain.

    Mucuna Pruriens has been used in Ayurveda medicine since 1500 B.C. For treating things like snakebite, intestinal problems, sexual issues and melancholy mood. Research shows that supplementing with L-DOPA as Mucuna Pruriens extract is a great natural antidepressant.[xii]

11. N-Acetyl L-Cysteine (NAC) – NAC is an amino acid that regulates the amount of glutamate and dopamine in your brain. And is a precursor to glutathione which reduces free radicals.

    A study with 75 subjects with bipolar disorder were given 1 gram of NAC twice daily for 24 weeks. Treatment with NAC caused a significant improvement with depression in these patients.[xiii]

12. N-Acetyl L-Tyrosine (NALT) – NALT is a highly bioavailable form of the amino acid L-Tyrosine. Your brain uses tyrosine to produce dopamine and norepinephrine. Dopamine is involved in libido, memory, focus, goal-oriented concentration, a mood elevator and antidepressant.

    If you are ADHD, or have other issues with low dopamine, supplementing with NALT may help improve your memory, boost your IQ, and relieve depression. I highly recommend NALT for anyone using stimulants like Adderall or Ritalin for treating ADHD.

13. Nefiracetam – One of the newer members of the racetam-family of nootropics, Nefiracetam is used clinically to treat and prevent seizures, severe depression and has shown neuroprotective qualities.

    The structure of Nefiracetam is similar to the other great racetam antidepressant Aniracetam. Researchers at the University of Iowa did a trial with 159 stroke patients with major depression. The study concluded that Nefiracetam produced a significant improvement in the most severely depressed patients.[xiv]

14. Noopept – This peptide-derived nootropic related to the racetam-family is much more potent than Piracetam. But its mechanism of action in your brain is similar to other racetams.

    Noopept stimulates dopamine, nicotinic and serotonin receptors. And boosts cognition, memory, logical thinking, reflexes and mood.[xv] Noopept increases Alpha and Beta brain waves. Increasing relaxation. And moving you into super-learning, flow states and joy.

15. Phenylalanine – This amino acid is a precursor to tyrosine in your brain. Tyrosine helps in the formation and utilization of dopamine, epinephrine, norepinephrine and melatonin.

    One study was done with 23 patients diagnosed with depression who had not responded to standard antidepressants. They were given 50 or 100 mg of Phenylalanine daily for 15 days. The researchers found that Phenylalanine completely improved mood in 17 of the patients. Within 13 days of the 15-day trial.[xvi]

16. Rhodiola Rosea – Rhodiola activates AMPA receptors in your brain. Which decreases depression and stress-related mood swings, reduces fatigue, stimulates energy and alertness, and boosts cognition.

    A clinical trial with 57 patients diagnosed with depression were given Rhodiola Rosea extract, sertraline (Zoloft^®), or a placebo for 12 weeks. The study found that Rhodiola was slightly less effective than sertraline for depression. But produced far fewer side effects and was better tolerated.[xvii]

17. SAM-e – SAM-e is the naturally occurring amino acid methionine bound to an ATP molecule. It helps in the process of cell division and repair, and the generation of the neurotransmitters dopamine, serotonin, norepinephrine and melatonin. Which is why it’s considered a potent nootropic.

    SAM-e is used to boost mood, relieve depression, improve energy levels and reduce symptoms of fibromyalgia. 20 healthy volunteers took part in a study receiving infusions of 800 mg of SAM-e or a placebo for 7 days. EEG mapping during the study identified SAM-e as an antidepressant. Targeting brain regions crucial in the therapeutic efficacy of antidepressants.[xviii]

18. St. John’s wort – This plant has traditionally been used for mood disorders and wound healing. Today it’s used mostly as a treatment for anxiety, depression and stress.

    St. John’s wort works like prescription SSRI’s by preventing the reuptake of serotonin in your brain. But please read the precautions for using this nootropic in the extended article. Before trying it as a nootropic supplement to treat your depression.

19. Sulbutiamine – Sulbutiamine is a synthesized version of Vitamin B₁ (thiamine) which easily crosses the blood-brain barrier. As a nootropic, it’s taken to boost mood, memory and motivation.

    A study at the University of Wales Swansea in the UK worked with 120 young adult females. Study participants took either a placebo or 50 mg thiamine for 2 months. Mood, memory and reaction times were monitored before and after taking the tablets. 2 months after supplementing with thiamine, participants were more clearheaded, felt more composed and energetic, reaction times improved, and mood was better.[xix]

20. Tryptophan – This essential amino acid is a precursor to serotonin and melatonin and niacin (Vitamin B₃) in your body. Adding tryptophan to your stack can help boost your serotonin levels. And should help with anxiety, ADHD, depression, insomnia, memory loss, pain and eating disorders.
21. Turmeric– Turmeric is one of the main spices in curries. In parts of India where curries are eaten most often, Alzheimer’s disease is extremely rare. This spice (and its extract called curcumin) has a unique ability to reduce inflammation common to Parkinson’s, Alzheimer’s and brain tumors.

    A study conducted in India looked at the efficacy and safety of using curcumin, one of the active ingredients found in turmeric, for treating major depression.

    60 depressed patients took either 20 mg of Prozac^®, 1000 mg of curcumin, or a combination of both daily for 6 weeks. The best response during the trial was with patients using the two. And the researchers concluded that curcumin could be used as an effective and safe treatment for patients with major depression.

22. Uridine Monophosphate – This precursor to Ribonucleic Acid (RNA) provides instructions to your DNA to help create memory by facilitating connections between brain neurons (synapses).

    Uridine supplementation as a nootropic uplifts and stabilizes mood, is anti-stress, helps Obsessive Compulsive Disorder, is anti-anxiety and helps modulate and normalize dopamine release.[xx]

23. Vitamin B₆ – Vitamin B₆ helps your brain make serotonin, norepinephrine and melatonin. The activated form of Vitamin B₆ called P-5-P is particularly effective in boosting serotonin and GABA in your brain.

    For depression, look for a P-5-P supplement or a B-Complex formula that uses P-5-P.

24. Vitamin B₁₂ – This B-vitamin plays a key role in the efficient conversion of carbohydrates to glucose – your cell’s source of fuel. It also helps your body convert fatty acids into energy.

    Supplementing with Vitamin B₁₂ can help lower anxiety, and elevate alertness, cognition, energy, vision, elevate mood and relieve insomnia. No more mood swings!

Depressed No More

Nootropics are a strong alternative to many antidepressant medications currently prescribed by doctors. And promoted by the Big Pharmaceutical companies.

But a very strong word of caution – if you are currently using any prescription antidepressant medications. Or any medication for that matter. Research each nootropic including side effects and prescription drug interactions before using them.

To finally beat depression, you must figure out the root cause of it. It is pointless to try otherwise without doing your research. And experimenting with various nootropic supplements until you find out what works for you.

Good luck in your search. There is hope. I know because I’ve conquered my depression. And come out the other side better than before.
