Analysis

Two tablets provide 770 mg of deglycyrrhizinated licorice root extract. That ingredient defines the product's digestive purpose, while glycine appears at only 100 mg.

The DGL amount is clear but lacks extract-standardization details. Glycine is far below a focused dose and should not be used to compare this with dedicated glycine supplements.

Ninety servings support regular use for someone specifically seeking a DGL tablet. Value depends on the digestive formula rather than the small amount of glycine.

Who is it for
  • Adults specifically seeking DGL licorice
  • Users who prefer tablets
  • People not relying on it for glycine
Best for
  • DGL-centered digestive support
  • Longer tablet routines
  • Combined DGL and minor glycine intake

Pros

  • Provides 770 mg DGL root extract
  • Clearly states both active amounts
  • Ninety servings
  • Deglycyrrhizinated licorice format

Cons

  • Only 100 mg glycine
  • DGL standardization is not stated
  • Requires two tablets
  • Poor glycine-specific value

Warnings

  • People with a licorice allergy should avoid the DGL root extract.
  • Deglycyrrhizinated licorice is processed to reduce glycyrrhizin, but users with heart, blood-pressure, or kidney conditions should still verify suitability with their clinician.
  • Taking several tablets to obtain more glycine would also multiply the DGL dose and is not appropriate without label guidance.

Nutrient quality

87 Highest impact

Deglycyrrhizinated licorice and glycine in tablets gives the formula reasonable ingredient quality. The amounts are useful, though dose depth or delivery detail leaves room for improvement.

Ingredient transparency

84 Highest impact

The meaningful actives and their amounts are clearly identified. Serving guidance and the complete inactive-ingredient list are not fully supplied.

Customer satisfaction

69 High impact

The aggregate rating is favorable and supported by useful review volume. No review excerpts are supplied to assess repeated complaints or purpose-specific experiences.

Value for money

83 Highest impact

Formula quality provides fair value for the category. Serving value is reasonable, with trade-offs in delivery or disclosure.

Glycine is a small secondary ingredient in a DGL-centered chewable, so it is poorly aligned with stand-alone glycine use. The amount is clearly disclosed, but source quality and other ingredients are not available for review. Its value is better judged as a combined digestive formula than by glycine alone.

Glycine Powder

Metabolic Maintenance
<p>Glycine Powder provides a stronger or more purposeful glycine profile than the original for focused glycine use. The single-ingredient powder is easy to assess and practical to scale toward a multi-gram intake. The disclosed serving is useful, though no premium purity grade or source certification is provided.</p>
84 Performance

Glycine 1000 mg

Life Extension
<p>Glycine 1000 mg provides a stronger or more purposeful glycine profile than the original for focused glycine use. A clearly measured gram-level serving gives the focused capsule useful support for glycine-related pathways. Several capsules may be needed for higher multi-gram use, while source grade and inactive ingredients are not supplied.</p>
78 Performance

Glycine

Pure Encapsulations
<p>Glycine provides a stronger or more purposeful glycine profile than the original for focused glycine use. The focused formula supplies a useful intermediate glycine amount with clear active disclosure. A multi-capsule serving, very limited review volume, and no stated source grade keep the value only moderate.</p>
83 Budget

Pharmaceutical Grade AjiPure Glycine 500 mg

Swanson Ultra
<p>A lower serving cost makes Pharmaceutical Grade AjiPure Glycine 500 mg a more economical choice than the original. A branded pharmaceutical-grade source gives the simple capsule unusually clear raw-material quality. The serving remains modest for multi-gram glycine use, and the inactive-ingredient list is not supplied.</p>
80 Budget

Glycine 500 mg

Solgar
<p>A lower serving cost makes Glycine 500 mg a more economical choice than the original. The simple capsule clearly discloses glycine but provides an entry-level amount that may require several capsules for multi-gram use. Practical pricing and extensive feedback help, while source grade and inactive ingredients remain unclear.</p>
80 Budget

Glycine 500 mg

Country Life
<p>A lower serving cost makes Glycine 500 mg a more economical choice than the original. The disclosed glycine amount is modest, while vitamin B6 adds a relevant cofactor without solving the low glycine dose. Accessible value and broad feedback are positives, but source grade and inactive ingredients remain unclear.</p>
82 Value

Advanced Magnesium Complex

AOR Advanced Orthomolecular Research Advanced
<p>Advanced Magnesium Complex offers a more useful balance of glycine relevance and recurring cost than the original. Several absorbable magnesium forms and a substantial glycine yield make this a well-designed foundational mineral formula. The label does not separate how much elemental magnesium comes from each form, and several carriers overlap in purpose.</p>
79 Value

Melatonin 2 mg

Metabolic Maintenance
<p>Melatonin 2 mg offers a more useful balance of glycine relevance and recurring cost than the original. A practical melatonin amount gives the simple capsule strong alignment with sleep timing and onset. Glycine is relevant but far below a focused standalone amount, and no release profile is supplied.</p>
83 Value

DGL Ultra

Nature's Way
<p>DGL Ultra offers a more useful balance of glycine relevance and recurring cost than the original. Standardized DGL in a simple capsule supports the product’s digestive purpose, while glycine is only a minor addition. Serving value is reasonable for the DGL formula but very weak for anyone primarily seeking glycine.</p>
