Doctor's Best High Absorption Magnesium Glycinate Lysinate for Sleep Support

Magnesium glycinate is already one of the better-absorbed forms of magnesium, but Doctor's Best takes it a step further with a magnesium glycinate lysinate chelate that the brand reports delivers up to 6x better absorption than standard magnesium. Each serving of this chelated magnesium supplement provides 200 mg of elemental magnesium per 2-tablet dose, with no buffering fillers or additives. The formula is 100% chelated, vegan, non-GMO, gluten-free, and soy-free, and each bottle contains 240 tablets.

Key Reasons People Use Magnesium Glycinate Lysinate

• Muscle and nerve support: Magnesium plays a central role in muscle contraction and nerve signaling, which is why it shows up consistently in routines for people dealing with cramping, tightness, or tension that lingers after exercise or through the day.
• Sleep quality: Many people use chelated magnesium at night because magnesium is involved in regulating cortisol and supporting melatonin, two key factors in how well you wind down and stay asleep.
• Digestive tolerance: Standard magnesium forms like oxide and citrate can cause loose stools at higher doses. A fully chelated form like glycinate lysinate is designed to minimize that and can generally be taken at any time of day without a meal required.

What's Inside and How It's Made

Each tablet contains magnesium from 2,000 mg magnesium glycinate lysinate chelate, providing 100 mg elemental magnesium per tablet (200 mg per 2-tablet serving). Inactive ingredients are microcrystalline cellulose, croscarmellose sodium, magnesium stearate from a vegetable source, stearic acid, and modified cellulose coating. Doctor's Best states the formula contains no buffering fillers or additives. The brand has been producing research-backed supplements for over 35 years.

How to Use Magnesium Glycinate Lysinate Day to Day

Take 2 tablets twice daily, with or without food, as directed on the label. Many people split doses into one in the morning and one in the evening, though some prefer taking both at night to support sleep. If you're new to magnesium supplementation, starting with one tablet and adjusting based on how your body responds is a reasonable approach before reaching the full daily amount. Store in a cool, dry place. As with any supplement, dosing frequency and timing should be discussed with your provider, especially if you're managing a health condition or taking other medications.

Who It's a Good Fit For

This is a practical option for adults who want a chelated magnesium supplement that's easy on digestion and free from common allergens including gluten and soy. It works well for people who have had GI side effects with other magnesium forms, or who want flexibility around whether they take it with food. Because magnesium can interact with certain medications and health conditions, anyone who is pregnant, nursing, or managing a chronic condition should check with their provider before starting. This is a tablet form, not a powder or capsule, which is worth noting for anyone who has difficulty swallowing tablets.

What Customers Say

People consistently reach for this supplement when dealing with muscle cramps, and the feedback on that front is positive. Headache relief is also a theme that comes up in customer experiences. Overall, customers describe it as a solid, reliable magnesium supplement and note satisfaction with the product quality.
