Poor sleep can work against almost every health goal you have.
Sleep problems can show up in many ways:
Insomnia, waking up in the middle of the night, nighttime allergies, waking up exhausted, etc.
If two people say, “I’m not sleeping well,” they may be dealing with completely different sleep issues – and they may need very different solutions, which is why it helps to identify your sleep pattern first. Once you know what kind of sleep problem you’re dealing with, it becomes much easier to figure out what to do instead of guessing.
I regularly see these three sleep disturbance patterns:
- People who have trouble falling asleep.
- Those who wake up around 2 or 3 a.m. and can’t get back to sleep.
- People who sleep through the night, but wake up exhausted.
These are not the same problem, and they often have different contributing factors and need different support.
If You Can’t Fall Asleep
Difficulty falling asleep often involves one or both of these patterns: your internal clock is off, or your nervous system is still too active at night.
Melatonin:
Melatonin can help when circadian timing or a shifted sleep schedule is the issue. It works by signaling your brain’s internal clock, not by sedating you. That is why timing matters. For many people, melatonin works better when taken earlier in the evening rather than right at bedtime.
That said, most adults I see do not actually need melatonin unless there is a clear timing issue. More often, the nervous system simply is not calming down at night. However, poorly timed melatonin may miss the real issue or leave some people feeling groggy.
Glycine:
One of the simplest options for this pattern is the amino acid glycine. Research suggests around 3 grams before bed may support sleep quality and next-day function. It helps the body drop its core temperature slightly and supports calming signals in the nervous system.
Magnesium:
The mineral and electrolyte magnesium supports different pathways involved in relaxation, muscle tension, and calming neurotransmitters. Magnesium glycinate is often a good place to start because it is well absorbed and gentle for many people. We also carry magnesium blends that are specifically designed for calming and sleep support, such as OrthoMolecular’s CereMag.
Botanicalm PM:
Another option, especially when the mind feels active at night, is Botanicalm PM by OrthoMolecular. This formula combines herbs traditionally used to support calming and relaxation, including passionflower, lemon balm, and valerian root and may allow the body to settle into sleep more easily. This tends to work well for people who feel tired but still “on” at night.
If You Wake Up in the Middle of the Night
Waking up in the middle of the night is often tied to cortisol patterns, blood sugar shifts, inflammation, allergies, histamine, or something the body is reacting to. Melatonin does not reliably fix this pattern.
So how do you figure out what is actually going on?
This is where skilled muscle testing becomes useful in my office. Instead of randomly trying different supplements and hoping something works, I use muscle testing as one of my primary assessment tools to help narrow the search, identify patterns, and choose more individualized nutritional support.
During a session, we can evaluate possible factors affecting your sleep and help you get on a more targeted plan. If needed, we can also order lab testing related to inflammation, hormones, neurotransmitters, cortisol patterns, allergies (food, environmental, mold, additives), sensitivities and more.
A practical place to start is a cortisol test, which can be done at home using saliva samples. It costs a little over $100 and can provide useful and valuable information. For a little extra, you can even take a sample when you wake up during the night to see whether cortisol is elevated around that time.
Muscle testing does not replace your history, exam findings, or lab testing when lab testing is appropriate. It gives us another layer of clinical information that helps make the process more specific than a generic “one size fits all” supplement protocol.
If You Sleep but Don’t Feel Rested
If you sleep through the night but still wake up tired, this is usually a sleep quality issue – not just a sleep quantity issue.
- Deep sleep – Your body does much of its repair and recovery during deep sleep.
- Rapid eye movement (REM) sleep – Your brain uses REM sleep to process information, support memory, and help regulate mood.
When those stages are not happening well, you may get enough hours of sleep but still feel off the next day.
Glycine can be helpful here as well – not by forcing sleep, but by improving how efficient and restorative sleep may be.
Studies regularly link regular resistance training with improved sleep quality and deeper sleep stages over time. Free weights, resistance bands, weight machine training, and suspension training are all great examples of resistance training.
Another option I’ve started carrying in the office is SleepTides by Biotics Research. It contains bioactive peptides that work differently than many common sleep supplements. Rather than working like a sedative, it is designed to support the body’s natural cortisol rhythm. For people who have already tried foundational options like magnesium, glycine, caffeine timing, and sleep hygiene but still do not feel rested, SleepTides may be worth considering as part of a more individualized sleep-support plan.
Biotics Research also offers a dual peptide formula called SleepTides Synergy. It combines PeptiSleep™, which is designed to support a healthy cortisol rhythm, with Lactium®, a milk-derived peptide used to support calming GABA-related pathways.
Biotics Research also offers a brand new dual peptide formula called SleepTides Synergy. It combines PeptiSleep™, which is designed to support a healthy cortisol rhythm, with Lactium®, a milk-derived peptide used to support calming GABA-related pathways.
For people who have already tried things like magnesium or glycine and still are not getting deep, restorative sleep, SleepTides and SleepTides Synergy have been two of the more interesting additions I’ve seen. If your sleep still is not where it should be, I can help you decide whether one of these may be a good fit.
A Simple but Important Factor: Caffeine
One of the most common things that affects sleep is caffeine being used too late in the day.
Caffeine blocks adenosine, one of the main signals that builds sleep pressure – your body’s need to sleep. Even if you can fall asleep, caffeine can still reduce deep sleep and overall sleep quality.
One controlled study showed that caffeine taken even 6 hours before bedtime can disrupt sleep. A practical guideline is to stop caffeine by around 12–1 p.m., and even earlier if you are sensitive.
An Overlooked Factor: Histamine
Histamine is not just involved in allergies. It also acts as a wake-promoting neurotransmitter in the brain. When histamine is elevated at night, it can contribute to insomnia, anxiety, and waking in the middle of the night.
This is one reason why antihistamines like Benadryl, also known as diphenhydramine, can make people drowsy. However, medications like this have anticholinergic effects, meaning they block acetylcholine activity. Acetylcholine is important for brain function, memory, and nervous system regulation. Long-term use of anticholinergic medications has been associated with increased risk of cognitive decline and Alzheimer’s disease in some studies, so I do not recommend using them regularly for sleep.
For some people, addressing allergies, food sensitivities, dust mites, bedding, detergents, or overall histamine load can make a noticeable difference.
If you are reacting to something in your environment or something you ate before bed, that histamine response may wake your brain up right when your body is trying to calm down.
I can help you evaluate whether histamine may be part of your sleep issue and whether supplements that support healthy histamine balance, such as Natural D-Hist by OrthoMolecular or HistaQuel by Researched Nutritionals, may be appropriate.
How Much Sleep Do You Actually Need?
Most adults need about 7 to 9 hours of sleep per night.
Consistently getting less than 6 hours has been associated with increased risk of cardiovascular disease, insulin resistance, weight gain, and cognitive decline.
Many people focus on eating better, exercising, improving metabolism, or using weight-loss support strategies, but sleep is a huge part of your body’s metabolism, appetite regulation, blood sugar control, recovery, and ability to burn fat efficiently.
In other words, poor sleep can work against almost every health goal you have.
Putting It All Together
Sleep is not controlled by one single system. It involves your neurotransmitters, circadian rhythm, nervous system, hormones, immune system, blood sugar regulation, and brain function all working together.
If one piece is off, the whole system can feel off.
When sleep improves, people often notice better energy, clearer thinking, better mood, better recovery, and more stable metabolism.
You are a unique individual, and what works for your friends or family may not work for you. Instead of playing the guessing game with sleep supplements, I can help you figure out what your body needs.
Using muscle testing, we can evaluate your body systems, uncover underlying stressors (food sensitivities, toxins, mold, immune or inflammatory stressors, etc.), and identify lifestyle habits and targeted supplement options — so we can build a plan that actually fits you, your sleep pattern, and your health goals.
If you want help figuring this out, schedule a Functional Medicine/Nutrition Response Testing (NRT) appointment, and we’ll work through it together.
