Magnesium: The Relaxation Mineral


Magnesium is like a natural relaxant for your body. It helps calm the nervous system and relax muscles, setting the stage for deep, restful sleep. Plus, it supports GABA (gamma-aminobutyric acid), a neurotransmitter that promotes relaxation.


How to get more magnesium:


  • Leafy greens: Spinach, kale, and Swiss chard are packed with magnesium. Add them to salads, smoothies or as a side dish.
  • Nuts and seeds: Almonds, pumpkin seeds, and sunflower seeds are magnesium-rich. Snack on a handful or sprinkle them over your meals.
  • Whole grains: Brown rice, quinoa, and whole wheat bread are great sources. Choose these over refined grains.
  • Fish: Fatty fish like salmon and mackerel also provide magnesium and other sleep-friendly nutrients.


Melatonin: The Sleep Hormone


Melatonin, often called the sleep hormone, regulates your sleep wake cycle. It's produced by your pineal gland in response to darkness, signaling to your body that it's time to sleep.


How to Boost Melatonin Naturally:


  • Tart Cherries: Tart cherry juice and dried tart cherries are natural sources. Enjoy a small glass of tart cherry juice in the evening.
  • Grapes: The skin of grapes contains melatonin. Snack on a handful of grapes before bed.
  • Tomatoes: Add tomatoes to your salads, sandwiches, or sauces.
  • Walnuts: These nuts offer melatonin and healthy fats. Have a few walnuts as a bedtime snack.


Tryptophan: The Serotonin Precursor


Tryptophan is an amino acid that your body converts into serotonin, which then turns into melatonin. This helps regulate your sleep patterns and mood.


How to get more tryptophan:


  • Turkey and Chicken: These are well-known sources of tryptophan. Include lean poultry in your dinners.
  • Milk and Dairy: A warm glass of milk before bed can be soothing and provides tryptophan.
  • Nuts and Seeds: Pumpkin seeds, sesame seeds, and almonds are loaded with tryptophan.
  • Legumes: Beans, lentils, and chickpeas are excellent plant-based sources. Add them to soups, stews, and salads.


Vitamin B6: The Enabler


Vitamin B6 is key for converting tryptophan to serotonin and melatonin, making it crucial for your sleep-wake cycle.


How to get more vitamin B6:


  • Chickpeas: Use these versatile legumes in salads, stews and hummus.
  • Tuna and Salmon: These fish are rich in B6 and also offer omega-3 fatty acids.
  • Bananas: Convenient and tasty, bananas are a great source of B6. Enjoy them as a snack or add to smoothies.
  • Chicken and Turkey: Lean poultry provides a good amount of B6. Include these in your regular meals.


Calcium: The Sleep Supporter


Calcium helps your brain use tryptophan to make melatonin, supporting the sleep process.


How to Get More Calcium:


  • Dairy Products: Milk, cheese, and yogurt are classic sources of calcium. Try a small serving of yogurt as an evening snack.
  • Leafy Greens: Kale, collard greens, and broccoli are rich in calcium. Add these to your meals regularly.
  • Almonds: A handful of almonds provides calcium and magnesium.
  • Tofu: This versatile soy product can be added to stir-fries, salads, and soups.


Vitamin D


Vitamin D is associated with better sleep quality. While your skin makes it when exposed to sunlight, dietary sources are also important.


How to Get More Vitamin D:


  • Fatty Fish: Salmon, mackerel, and sardines are excellent sources.
  • Fortified Dairy Products: Milk and yogurt often have added Vitamin D.
  • Egg Yolks: Include eggs in your breakfast or meals.
  • Mushrooms: Certain mushrooms, like maitake and shiitake provide Vitamin D, especially when exposed to sunlight.


Omega-3 Fatty Acids: The Brain Boosters


Omega-3 fatty acids, particularly DHA, help with sleep by influencing melatonin production.


How to Get More Omega-3s:


  • Fatty Fish: Regularly include Salmon, mackerel, and sardines in your diet.
  • Flaxseeds: Add ground flaxseeds to your smoothies, oatmeal, or salads.
  • Chia Seeds: Use these in puddings, smoothies, or sprinkle on yogurt.
  • Walnuts: A convenient snack that provides omega-3s and melatonin.


Potassium: The Balancer


Potassium works with sodium to help regulate fluid balance and muscle function, impacting sleep quality.


How to Get More Potassium:


  • Bananas: An easy and Nutritious source of potassium.
  • Sweet potatoes: Roast them, mash them, or use them in soups.
  • Avocados: Add them to salads, toast or smoothies.
  • Spinach: Use fresh spinach in salads or cook it in various dishes.


Iron: The Literal Sleeper Mineral


Iron deficiency is linked to many conditions such as restless leg syndrome (RLS), for example, which can disrupt sleep. Consuming iron rich foods can help prevent these conditions.


How to Get More Iron


  • Red Meat: Beef and lamb are rich in iron. Opt for lean cuts and include them in your meals.
  • Spinach: Spinach is rich in iron and calcium. Add it to smoothies, salads, or cooked dishes.
  • Lentils: These legumes are an excellent plant-based source of iron. Use them in soups, stews, and salads.
  • Quinoa: A versatile grain that can be used in salads, as a side dish, or in breakfast bowls.


Zinc: The Immune Supporter


Zinc helps regulate sleep and produce melatonin.


How to Get More Zinc:


  • Oysters: One of the richest sources of zinc. Enjoy them as a special treat.
  • Beef and Pork: These meats provide substantial amounts of zinc.
  • Pumpkin seeds: Snack on these or add to salads and yogurt.
  • Lentils: Incorporate lentils into your meals for a plant-based zinc boost.

The thought that if you are a "healthy person" you will never get sick is a myth. In fact, i t’s perfectly normal to get sick every once in a while. This shows that our immune system is functioning the way that it was created to and defending us from unwanted invaders. With the onset of the pandemic, boosting the immune system to fight off the coronavirus has been a massive topic. But I feel like sometimes this topic gets thrown out and sets unspoken expectations that if your immune system is “boosted” that it will keep you from getting sick. And honestly, it’s all a matter of semantics, but I feel the need to clarify in clear words what the goal is for a healthy immune response. My true goal as a licensed physician and Naturopathic Doctor when I say “boosting the immune system” is to help your body correctly and effectively take care of bacteria and viruses (any unwanted microbe) that may enter your system. This does not mean that you will not get sick with the flu, cold, or whatever is going around. This means that your body is able to quickly identify and eliminate the intruder given the body’s natural elimination pathways. This often looks like producing mucus, coughing, healthy fever levels, etc. All the symptoms that people associate with being sick, is your body’s immune system functioning the way it is supposed to. The length of appropriate symptoms varies based on what the body may be fighting off. For example, colds and flus can last from 3 to 7 days. The key is that the body is able to react, recover and heal with support of the immune system and the person returns to normal quite quickly within a matter of days. The goal of optimizing immune system function is avoiding the UNWANTED results of a dysfunctioning immune system. This can be one of two things. The dysfunctional immune system can be underfunctioning or overfunctioning. Underfunctioning - This is where the body has a harder time identifying and overcoming the invader. The infection can then get a stronger hold and create worse symptoms, or take longer to eliminate and drag the symptoms out for a long time. This is often seen as being sick for weeks and having lingering symptoms that just don’t seem to go away, or getting sick frequently as if they keep getting “reinfected.” Many lifestyle, nutrition, medication factors can go into this. Suppression of symptoms and therefore suppression of the immune system reaction can also contribute to this. (That’s a whole other topic for discussion though.) Overfunctioning - Where the immune system finds the intruder and then overreacts, creating worse symptoms than necessary to eliminate it. The most common manifestations of an overactive immune system are things like asthma, autoimmune diseases, and asthma. More short term manifestation can can sometimes be the picture that we see in regards to the acute respiratory distress caused by a cytokine storm in Covid-19 patients. The immune system is overreacting and actually causing unwanted effects in the person. And it must be noted that the imbalance of the immune system can be a combination of both the under reaction and the overreaction. For example, the body can under react to an infection which can then later create an overreaction if the infection gets bad enough. So there is a huge spectrum and so many different ways dysfunction of the immune system can occur. The important thing to be able to recognize when there is dysfunction and how to manage that. When creating a healthy and optimized immune system, the goal is NOT to never get sick. The goal is to have an immune system that responds correctly and effectively toward pathogens, because sometimes... getting sick actually means that the immune system is functioning the way it should.

There has been lots of talk about what has become known as "gut-health.” Even the Johns Hopkins Medical Center website mentions it, one of the most well-respected hospitals and Medical Schools in the United States, there is a good reason for this. Hidden within the walls of your digestive system is a nervous system layer... what is known as “your second brain” and this “brain in your gut” is changing the way that we look at the links between mood, digestion, health and even the way that you think.

The thyroid is a small butterfly shaped gland at the bottom of of the neck. This gland is in charge of the "metabolism" or in other words, the energy of the body. Thyroid hormone plays a role on each cell of the body. The hormone enters the cell and activates the DNA to perform the job that the cell is made to do. If the cell is not getting the hormone it needs, then it won't function properly. This can be any cell in the body, which is why the symptoms of low thyroid can be so widespread throughout the body.
