Or you wake up and can't get back to sleep no matter what you do. You've tried sleep apps, blackout curtains, white noise machines. Nothing works.
The answer might be simpler than you think. Your sleep quality is partly determined by what you ate at dinner.
Sleep is partly nutritional
Sleep isn't purely neurological. It's also nutritional. Your body needs specific amino acids and minerals to produce neurotransmitters and hormones that enable sleep. If those nutrients are missing, sleep suffers.
Glycine, magnesium, tryptophan, and taurine all play roles in sleep initiation and sleep depth. If your diet is chronically deficient in these compounds, you might fall asleep fine but struggle with sleep maintenance and deep sleep.
Most processed food diets are deficient in these nutrients. You can address this with supplements, but far better is food. Bone broth, red meat, fish, eggs, and dairy all provide sleep-supporting nutrients. The difference in sleep quality when these foods are part of your regular diet is often dramatic.
Fragmented sleep or sleep that doesn't refresh you is often a sign of nutritional insufficiency. Fix the nutrition and your sleep fixes itself.
The key is to understand which nutrients matter for sleep and which foods provide them. Once you do, you can shape your evening meal to actively support sleep rather than sabotage it.
Glycine and deep sleep
Glycine is a simple amino acid that's essential for sleep. It's used by the body to produce glutathione (a master antioxidant) and creatine (essential for cellular energy).5 But more directly relevant to sleep, glycine reduces core body temperature and activates GABA receptors, which promotes sleep onset and sleep depth.
Research shows that glycine supplementation improves sleep quality, reduces time to sleep onset, and increases deep sleep time.1 But you don't need to supplement. Glycine is found in significant amounts in bone broth, skin-on chicken, gelatinous meat cuts (like bone-in ribs or stew meat), and fish skin.
The most practical source is bone broth. A cup of bone broth before bed provides meaningful amounts of glycine, magnesium, and minerals that all support sleep. Many people report that adding bone broth to their evening routine improves their sleep within a single night.
Bone broth at dinner or before bed is arguably the single simplest intervention for improving sleep quality. The glycine content alone makes it worth doing.
If you're making your own bone broth, longer simmering times (12 to 24 hours) extract more gelatin and glycine. Store-bought bone broth also works, though the longer-simmered homemade versions are superior.
Magnesium and sleep quality
Magnesium is responsible for over 300 enzymatic reactions in the body, and it's essential for nervous system relaxation and sleep.2 Magnesium activates the parasympathetic nervous system (rest and digest), which is required for sleep onset. It also helps regulate GABA and serotonin, both critical for sleep.
Most people are chronically deficient in magnesium. The modern diet provides inadequate amounts, and stress, caffeine, and alcohol deplete magnesium stores further. The result is that many people are literally unable to relax deeply because their nervous system doesn't have the mineral resources to shift into parasympathetic mode.
Food sources of magnesium: leafy greens, particularly dark greens like spinach and kale (though raw greens contain oxalates that inhibit mineral absorption, so cooked is better), pumpkin seeds, almonds, fish, and shellfish. If you're eating these foods regularly, magnesium status is probably adequate. If your diet lacks these foods, magnesium deficiency is likely.
If you can't fall asleep or can't stay asleep, magnesium deficiency should be your first hypothesis. A simple swap toward magnesium-rich foods often resolves the problem within a week.
Practical evening approach: include leafy greens or shellfish at dinner. If that's not appealing, magnesium supplementation (200 to 400 mg before bed) is reasonable. Magnesium glycinate is particularly useful because you get both the magnesium and the glycine benefit.

The protein and carbohydrate balance
A common sleep mistake is eating pure protein in the evening (meat and vegetables, no carbs). Whilst this is fine for general metabolism, it's suboptimal for sleep. Tryptophan, the amino acid precursor to serotonin, needs carbohydrates to be absorbed effectively across the blood-brain barrier.3
The mechanism: carbohydrates cause an insulin spike, which removes other amino acids from the bloodstream, allowing tryptophan to cross into the brain more readily. Without carbohydrates, tryptophan stays in the body but doesn't reach the brain as effectively.
The ideal evening meal: protein and fat (for satiety and nutrients) plus carbohydrates (for tryptophan absorption and serotonin production). This doesn't mean refined carbs or sugar. It means whole carbs: white rice, potatoes, sweet potatoes, or even just more leafy greens to get carbohydrate content up moderately.
If you're struggling to fall asleep despite adequate protein intake, the issue might be that you're not eating enough carbohydrates. Add white rice or potatoes to dinner and observe the effect on sleep.
The ratio matters less than the presence of both macronutrients. Some people do well with a 3:1 protein-to-carb ratio. Others prefer more balanced. The key is experimenting to see what your individual nervous system needs.
Tart cherry and natural melatonin
Tart cherry juice is one of the few foods that naturally contains meaningful amounts of melatonin, the hormone that regulates sleep-wake cycles. Tart cherry has been shown in research to improve sleep onset and sleep quality, particularly in people with mild insomnia.4
The mechanism is straightforward: tart cherry increases melatonin availability, which shifts circadian rhythm and promotes sleep. Unlike melatonin supplements, which can create dependence, tart cherry is a food and doesn't carry the same risks.
A small amount (one to two ounces, or a small glass) of tart cherry juice before bed can meaningfully improve sleep. Some people prefer tart cherry extract in powdered form (mixed into bone broth or other evening beverages) to avoid the sugar content of juice.
Tart cherry is one of the few food sources of natural melatonin. A small serving before bed often improves sleep within days.
Timing matters slightly. Tart cherry works best consumed 30 to 60 minutes before bed, giving the melatonin time to be absorbed and to begin shifting your circadian rhythm.
The practical evening meal
A sleep-supporting evening meal looks like this: a serving of protein (fish, meat, eggs, or dairy), a substantial serving of carbohydrates (white rice, potato, sweet potato, or root vegetables), plenty of cooked green vegetables (magnesium and minerals), and good fat (butter, olive oil, or tallow). Add bone broth as a beverage or as the cooking base.
If you want a simple pre-bed snack: bone broth with a small amount of white rice or potato stirred in, or a small amount of tart cherry juice mixed with bone broth. This combination provides glycine, magnesium, tryptophan, and natural melatonin, all working together to support sleep.
The timing: heavy meals close to bedtime (within 30 minutes) can interfere with sleep. Ideal is to eat your main meal 2 to 3 hours before bed, allowing time for initial digestion. A lighter pre-bed snack (bone broth, perhaps) 30 to 60 minutes before bed is fine and often helpful.
Your evening meal is a sleep preparation tool. Use it intentionally to provide the nutrients your nervous system needs to shift into parasympathetic mode and sleep deeply.
This approach usually improves sleep within 3 to 7 days. People report falling asleep more easily, staying asleep longer, and waking more refreshed. Once you've experienced sleep supported by proper nutrition, you'll never go back to relying on sleep aids or prescription medications.
