Analysis

One capsule provides 75 mg GutGard deglycyrrhizinated licorice root extract. The branded active and capsule format create a straightforward digestive product.

Glycine contributes only 50 mg, which is negligible for standalone use. Source purity for the glycine is not stated, and the formula should not be compared with dedicated amino-acid products.

Ninety servings and one-capsule dosing make it the most convenient DGL format in this group. The product fits DGL users, not shoppers seeking glycine.

Who is it for
  • Adults seeking a one-capsule DGL product
  • Users who prefer capsules over chewables
  • People not relying on glycine
Best for
  • Convenient GutGard DGL use
  • Longer digestive routines
  • Avoiding chewable carbohydrates

Pros

  • Uses branded GutGard DGL
  • One capsule per serving
  • Ninety servings
  • Avoids chewable carbohydrate

Cons

  • Only 50 mg glycine
  • No glycine purity information
  • Not useful for glycine goals
  • Single-purpose digestive formula

Warnings

  • People with a licorice allergy should avoid the DGL root extract.
  • Users with heart, blood-pressure, or kidney conditions should verify that the deglycyrrhizinated licorice format is appropriate for them.
  • Taking extra capsules for glycine would multiply the DGL dose and is not appropriate outside label directions.

Nutrient quality

90 Highest impact

Standardized GutGard DGL and glycine in capsules gives the formula strong ingredient quality. The amounts are useful, though dose depth or delivery detail leaves room for improvement.

Ingredient transparency

85 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

67 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

87 Highest impact

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

The capsule offers convenient delivery, but the glycine amount is only a minor addition to the licorice extract. Its exact weight is clear while source purity and grade remain undisclosed. Low serving cost cannot compensate for the very high cost per gram of glycine.

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>
81 Value

DGL Deglycyrrhizinated Licorice Root Extract

Swanson Superior Herbs
<p>DGL Deglycyrrhizinated Licorice Root Extract offers a more useful balance of glycine relevance and recurring cost than the original. The DGL-centered formula provides a clearly disclosed licorice amount and uses glycine only as a small companion. It may suit its digestive purpose, but it is poorly aligned with anyone seeking meaningful standalone glycine.</p>
