Theanine and Magnesium Glycinate: Gentle Sleep Support Supplements Explained
Posted by Caroline Wightman l The Pharmacy Network on 12th May 2025
Getting quality sleep is one of the most important things you can do for your health. However, for many, it’s easier said than done. As interest grows in natural, gentle ways to support better rest, new supplements are gaining attention for their calming and restorative properties. Two of the most talked-about are theanine and magnesium glycinate.
Here’s what you need to know about these trending ingredients and how they might help you drift off more easily and wake feeling refreshed.
What is Theanine?
Theanine is an amino acid naturally found in tea leaves, especially green tea. It’s best known for promoting relaxation without sedation — meaning it can help you unwind without making you feel groggy.
How Theanine May Help:
- Encourages relaxation by supporting alpha brain wave activity, the same brain waves linked with a calm yet alert state.
- May ease anxiety and stress, helping to quiet a busy mind before bed.
- Supports focus and mental clarity during the day, when taken in lower doses.
Theanine is often included in modern sleep blends to help create a smoother transition from wakefulness to sleep, especially for people who struggle with an overactive mind at night. New supplements available for purchase at The Pharmacy Network include:
Bioglan L-Theanine Calm and Focus
Bioglan Medlab Alpha Relax with Theanine
However, please talk to your health professional before adding theanine to your supplement regime if you are taking:
- Antidepressants
- Antipsychotic medications
- Sedatives (like benzodiazepines or sleeping tablets)
- Blood pressure medications
What is Magnesium Glycinate?
Magnesium glycinate is a form of magnesium bound to the amino acid glycine. This pairing makes it easier for the body to absorb and gentle on the stomach — important for those who don’t tolerate other forms of magnesium well.
How Magnesium Glycinate May Help:
- Promotes muscle relaxation, which can ease tension and discomfort that interfere with sleep.
- Supports the nervous system, helping to regulate stress responses.
- May improve sleep quality, particularly for those who have trouble staying asleep through the night.
Magnesium is essential for hundreds of processes in the body, including nerve and muscle function. Research suggests that many people aren't getting enough through diet alone. New magnesium glycinate supplements available for purchase at The Pharmacy Network include:
Metagenics Fibroplex Mag Active 4 Kids
However, please talk to your health professional before adding magnesium glycinate to your supplement regime if you are taking:
- Antibiotics (like tetracycline or ciprofloxacin)
- Blood pressure medications
- Diuretics
- Heart medications
Why Are These Supplements Trending?
With growing awareness around the importance of sleep for mental and physical wellbeing, more people are seeking natural solutions that work with, rather than against, the body’s rhythms.
Theanine and magnesium glycinate are attractive options because they:
- Are generally well tolerated
- Have calming effects without strong sedatives
- Can be used alone or alongside other healthy sleep habits (like reducing screen time and sticking to a regular sleep schedule)
New sleep formulas often combine these ingredients with others like melatonin, chamomile, or glycine to offer a multi-pronged approach to better rest.
