Healthy Highs: How To Improve Your Mood With Natural Supplements

By Jack Hafferkamp


It's winter. You're in a mental/physical place that is hard to define. You're not so depressed you want to jump out the window, but you're not happy. Everything is an effort and nothing is fun. Life is, well, blah. Those blahs are a sign of low-level depression. What to do? Prozac, Zoloft, Paxil? Maybe. But you should also consider putting into place some fairly obvious lifestyle changes along with taking supplements known as natural mood enhancers.

"There is a time and place, where one needs the big guns to save the proverbial bacon," says Dr. Chris D. Meletis, lead author of the Clinical Natural Medicine Handbook. "If the depression is persistent, worsening or life threatening talk to your doctor right away. Yet assuming you are feeling just a little melancholy, and are not wondering whether life is worth it, then natural mood enhancers are often an excellent choice." Natural substances like tryptophan, St. John's Wort, 5HTP, SAM-e, Rhodiola rosea, valerian root and others can and do improve mental outlook—the way you take on the world—without relying on prescription pharmaceuticals. These substances work in a variety of ways, including boosting levels of the brain's feel-good chemicals and better regulating your body's natural sleep rhythms. And, if used ‘wisely’, they are safe. They may also serve as a way to get off prescription mood enhancers.

The key word is wisely. Most doctors will tell you, with good reason, that self-medication is risky. On the upside, natural mood enhancers do not produce many of the common side effects of prescription antidepressants, things like suicidal tendencies, sexual dysfunction, urinary retention, constipation, blurred vision, headache, weight gain, gastrointestinal disturbance and on down a long, depressing list that ends with plain old dry mouth. On the other hand, mood-altering substances are serious things; they alter your body's chemistry. Depending on which ones you choose, these substances work to boost neurotransmitters, to regulate better your body's natural sleep rhythms, to prevent glandular atrophy and even to reduce the inflammation that has been linked to depression.

The fundamental starting point for successfully using natural mood improving supplements, according to Dr. Patricia Gerbarg, co-author of ‘How to Use Herbs, Nutrients and Yoga in Mental Health Care’, is that different supplements do different things. "You need to know what you are looking for. Some are better for energy, others improve stress resistance”, says Dr. Gerbarg. "One size does not fit all. Learn about the supplements from credible sources, not just from the companies that are trying to sell their products."

Neurotransmitters

To know what to take, it is necessary to define the problem, and a good place to start is with an understanding of the brain's neurotransmitters. These are the chemicals that relay, amplify, and modulate signals between a neuron and another cell in your brain, and their levels have a lot to do with how you feel. There are quite a few of them—about 50 identified so far—flowing in your head, but the most important for our discussion are serotonin, noradrenaline and dopamine.

Serotonin is the brain's feel-good neurotransmitter. It promotes feelings of wellbeing, resilience, calm, personal security, relaxation, confidence and concentration. Many people suffer from various degrees of brain serotonin deficiency, leading to a host of mental, emotional and behavioural problems, including depression, especially the agitated, anxious, irritable type. According to Dr. Meletis, serotonin deficiencies have been linked to a number of conditions, including anxiety, suicide, alcoholism, violent behaviour, PMS, obesity, compulsive gambling, insomnia, carbohydrate craving, SAD (seasonal affective disorder), and migraine headaches.

Clearly, keeping serotonin levels up is vitally important. One way to increase serotonin is with supplements containing the amino acid called 5-hydroxytryptophan. 5-HTP is the immediate precursor in the production of serotonin from the essential amino acid L-Tryptophan. It can be taken with meals and your body converts it to serotonin.

Another important neurotransmitter is noradrenaline. It helps to promote motivation and drive. Derived from dopamine, it is involved with ‘positive’ stress states such as being in love and other exhilarating and stimulating pursuits. Without it, one pulls the covers over one's head, and doesn't want to do much of anything. A third key neurotransmitter is dopamine. It is the primary neurotransmitter involved in the reward pathways in the brain. Drugs that increase dopamine signalling may produce euphoric effects. It is the neurotransmitter involved in the ‘pleasure-ability’ of recreational drugs such as cocaine and amphetamines. Problems with dopamine neurotransmission play a role in a variety of disorders, including Tourette's syndrome, Parkinson's disease, schizophrenia, attention-deficit hyperactivity disorder (ADHD), and drug and alcohol dependence.

These neurotransmitters work together in a delicate balance. Serotonin circuits help counterbalance the tendency of the other two to encourage over-arousal, fear, anger, tension, aggression, violence, obsessive-compulsive actions, overeating, anxiety and sleep disturbances. Both antidepressant drugs and natural supplements aim to enhance and rebalance mental interactions. Making any natural mood enhancers work for you is a juggling act that most likely will require behavioural and lifestyle changes: things like dropping the diet soda and artificial sweeteners; sleeping more regularly and actually exercising purposefully for at least two hours a week. For certain you need to think way beyond the ‘just take a pill’ mind set.

Sleep Therapy

Before you head off to the pharmacy, health food store, or computer to buy any supplements, you should consider enlisting the world's cheapest mood elevator: sleep. "America is a sleep deprived country," says Dr. Richard Brown, clinical psychiatry professor at Columbia University and co-author of ‘How to Use Herbs, Nutrients and Yoga in Mental Health Care’. Chronic lack of sleep, he says, predisposes us to diabetes and a host of other ailments. He points out that traditional Chinese doctors often tell patients they need to sleep better. "They recognize that different areas of the brain do their recovery and repair work at different times in the night."


On this point Drs. Brown and Meletis agree. It is good to give yourself permission to get enough sleep. "Make sure you are getting your eight hours of sleep," says Dr. Meletis, winner of the 2003 naturopathic physician of the year award from the American Assn. of Naturopathic Physicians. "After all, the first four letters of restoration are REST. Without rest, your body will not work well. Indeed, lack of sleep is a fool-proof way to void your body's warranty and lead to an overall systems failure, or at the least a spluttering down the road of life."

Of course, a measure of just how complex this all is—as well as how individualized solutions may be—is that for some people sleep itself is a big deal. Not being able to sleep because of anxiety calls for an entirely different solution than sleeping too much because of depression.

Eating Right

All three doctors agree on the importance of nutrition in restoring a sense of wellbeing. "Just like the 1970's Saturday Morning cartoons said, 'You are what you eat, from your head to your feet,'" says Dr. Meletis. "Junk in equals junk out.... according to the American Journal of Preventive Medicine, spring 2007, only 11 percent of Americans get their five to seven servings of fruits and veggies. That means 89 percent are missing the mark. It would be like putting the low octane grade of gas in a high performance car and wondering why it is not performing."

The basic keys, Meletis says, are to “drink four pints of filtered, non-chlorinated, non-fluorinated water daily. Also avoid excess carbs. Otherwise your brain, which runs largely on glucose, will be on a non-stop rollercoaster." One food additive almost everyone agrees is counter-productive is aspartame. It's the artificial sweetener in diet colas. Multiple studies have shown it depresses serotonin levels. People with a history of mood disorders or depression have been linked to bad reactions after consuming aspartame.

Good news: Changes in diet are not all about doing without things you may crave. It may also involve eating more of some things you enjoy. One of the most potent mood enhancers is found in some very common foods: chocolate, whole grain pasta, figs, fish, peanuts, milk, turkey, chicken, cottage cheese, avocados and bananas are rich in an essential amino acid called tryptophan. Guess what? It breaks down into serotonin.

Exercise

Dr. Brown says he sees a lot of men in their 30s coming to him complaining of low energy, mental fogginess and low libido. He often finds they have low levels of testosterone. What happens, he says, is that when men stop exercising and start putting on weight their bodies start producing more of the hormone oestrogen, which is more associated with women than men. Regular exercise—both for strength and cardio—brings up the testosterone level, which is important for that elusive feeling of wellbeing. And, it turns out that exercise also increases serotonin levels.

Again, Dr. Meletis agrees: "Having just written a book on male menopause, I can say clearly that one in four men has low testosterone levels at the age of 30. So, just like women have hormonal fluctuations, men can too and you don't have to wait until you are 50 to go through male-menopause. Signs of low testosterone are often depression, sleep disturbances, decreased muscle mass or increased body fat. Weaker erections can also occur. The key is to get tested and never self medicate with testosterone."

Light Me Up

When you notice a low mood occurring every year between November and March, it may be due to Seasonal Affective Disorder (SAD). Many people living in northern latitudes get depressed when deprived of adequate sunlight during the winter. A 10,000-lux SAD light box, delivers primarily blue-green light and exposure for 30 to 60 minutes every morning convinces the biological clock that it is summer and elevates mood.

Thyroid?

Dr. Meletis also suggests that a person feeling sluggish should get his thyroid levels tested. "Signs of low thyroid include depression and slower thinking relative to your individual capacity," he says. Dr. Brown in turn stresses that symptoms of low energy, sexual dysfunction, foggy head and low-level depression can have many causes, and that the absolute best bet for fixing things is to see your doctor. "Each person is unique. To get a complete picture it is necessary to get a complete history and battery of relevant tests. There are lots of kinds of depression and it often comes with a range of other problems: post-traumatic stress disorder, obsessive/compulsive disease, etc. Depression can be related to your thyroid, substance abuse or any number of things."

Dr. Brown recognizes that for many people signing on for a whole-scale diagnostic is, itself, a big deal. Lots of people would rather try self-medicating first. He doesn't see this as necessarily all bad. "When a person takes some action, they are getting the ball rolling," Dr. Brown says.

A Word of Caution

Buyer beware.... Dr Gerbarg puts it this way: "Because the natural supplement business is not closely regulated, the quality of products varies widely. It is important to do some research to be sure you are getting a product that is of good quality, properly manufactured and standardized for active ingredients, and without contaminants. "

Yeah, Yeah, But What Do I Take?

Having read this far, you may still be wondering where to begin. Dr. Brown's recommendations—with cautions - for supplements to go with are Rhodiola rosea and SAM-e. Rhodiola rosea (also known as Golden Root, Roseroot, Arctic Root) is a plant in the Crassulaceae family that grows in cold regions of the world. Dr. Brown believes it can be effective for improving mood and alleviating depression. Pilot studies on human subjects show that it improves physical and mental performance, reduces fatigue, and even minimizes high-altitude sickness. Dr. Brown says he has seen it be effective across several fronts: sexual functioning, athletic performance, weight reduction and mood elevation.

SAM-e (short for S-adenosylmethionine) is curious in that it stakes a claim for treating both depression and osteoarthritis. It is believed that SAM-e increases the availability of neurotransmitters serotonin and dopamine. SAM-e is an essential metabolite that is already present throughout the body. SAM-e is effective in treating mild to severe depression if taken in adequate doses. Because SAM-e readily reacts with oxygen, it is critical to get only the best quality brands. Only a few laboratories manufacture it properly. Bargain brands tend to be ineffective and cause more side effects. SAM-e also comes with some cautions. For example, people with bipolar disorder, anxiety disorders and other psychiatric conditions should only use SAM-e under supervision. Dr. Gerbarg says some people report feeling nausea.

Dr. Meletis offers this: Supplements to consider in general include: 5 HTP and St. John's Wort—but only if you are not taking conventional drugs of any sort. "My patients routinely start on either 5 HTP or St. John's Wort, or a combination called Positrol, offered by Complementary Prescriptions," says Dr. Meletis. "Positrol offers both 5 HTP and St. John's Wort in combination with B6. Vitamin B6 is important for the conversion of 5 HTP in the brain to serotonin. The Positrol is often used for those with melancholy but good overall energy and Syncholamine confers a little pick me up as well."

Dr. Gerbarg points to the value of some other dietary supplements as places to begin: "There are certain nutrients that are critical for maintaining normal transmission and cellular repair in the neural pathways involved in mood regulation. Anyone who is prone to depression could benefit from supplementing their diet with B vitamins, folate, and omega-3 fatty acids (from fish oil)."

Summing It Up

What are the things you should keep in mind when deciding to try out a mood supplement to combat light depression? Dr. Gerbarg gives these evaluation questions:

1. What are my symptoms: low mood, low energy, feeling overwhelmed by stress?
2. Am I getting enough sleep, exercise and good nutrition?
3. How can I reduce my stress?


"Discuss your depression with your doctor to get an objective opinion on how severe it is," she says. "If the depression is severe i.e. has gone on for several weeks or more, significantly interferes with your ability to work, or is accompanied by suicidal thoughts or severe anxiety, then you may want to consider starting a prescription antidepressant to get yourself stabilized as rapidly as possible." She elaborates that, "During the diagnostic evaluation, the doctor should also determine whether you have straightforward depression or something more complicated such as bipolar disorder, which requires a different medication approach."

"At the same time you can begin trying natural and complementary treatments as well as lifestyle changes. These will enhance your recovery but they may have a more gradual effect. If the natural treatments work well for you, it may be possible to reduce or taper off the prescription drugs faster."

Before you go out purchasing supplements because you've read an article, heard something on the radio or watched a programme on the TV, try and speak to someone who's really knowledgeable in the area first, like a nutritionist, naturopath or holistic practitioner.  And always ensure what supplements you do buy are from reputable, ethical sources.
