Omre Glycine + NAC is made for adults who want daily support for glutathione production, antioxidant defenses, cellular health, and healthy aging.
Each serving provides 1000 mg Glycine and 500 mg N-Acetyl L-Cysteine, also known as NAC. These two nutrients are commonly discussed together as GlyNAC because both provide building blocks the body uses to make glutathione, one of the body’s most important internal antioxidants.
Glutathione helps protect cells from everyday oxidative stress. It also plays a role in mitochondrial function, immune balance, and cellular maintenance. Since glutathione is a larger molecule, direct glutathione supplements may not always be the easiest option to compare. A Glycine + NAC supplement takes a different approach by supporting the body’s own glutathione production pathway.
Omre Glycine + NAC is not a medicine and does not treat, cure, or prevent disease. It is a daily supplement for adults who want a clean, tested formula with clear ingredient amounts.
What Is a GlyNAC Supplement?
A GlyNAC supplement combines glycine and N-Acetyl L-Cysteine, also known as NAC. These two nutrients help provide building blocks the body uses to make glutathione. Omre Glycine + NAC follows this GlyNAC-style approach by pairing 1000 mg Glycine with 500 mg NAC in one daily serving.
Why People Choose Omre Glycine + NAC
Omre Glycine + NAC is made for people who want glycine and NAC together in one simple formula, without buying two separate bottles.
Each serving gives you:
- 1000 mg Glycine
- 500 mg N-Acetyl L-Cysteine, NAC
- 30 servings per bottle
- Third-party lab testing
- Testing for dose, purity, bacteria, fungus, and heavy metals
- Made in the USA
- Made in GMP-certified facilities
- Doctor-developed formulation
- 30-day money-back guarantee
- Free US shipping on orders over $80
Many NAC supplements only focus on NAC. Many glycine supplements only focus on glycine. Omre combines both because they work together as glutathione precursors.
That makes it a strong fit for shoppers comparing the best NAC supplement, best glycine supplement, or a GlyNAC supplement for antioxidant and cellular defense support.
What This Glycine + NAC Supplement Supports
Omre Glycine + NAC is designed to support:
- Glutathione production
- Antioxidant defense
- Cellular health
- Healthy aging
- Oxidative stress balance
- Mitochondrial health
- Recovery support
- Everyday resilience
- Internal defense pathways
- Detoxification pathways
- Liver antioxidant support
- Immune defense support
Glycine + NAC does not work like a quick energy drink. Think of it more like daily nutrition for your body’s internal cleanup and defense systems. The goal is steady support, especially when used consistently as part of a healthy routine.
NAC is widely discussed in antioxidant and liver-support research because it helps supply cysteine, a key building block for glutathione. Glutathione plays a role in the body’s normal detoxification pathways, immune balance, and protection against oxidative stress. This does not mean NAC or GlyNAC “detoxes” the body like a cleanse. A better way to say it is that Glycine + NAC supports nutrients the body uses for its own internal defense systems.

Price and Serving Value
Omre Glycine + NAC is priced at $35.00 per bottle. Each bottle provides 30 servings.
That breaks down to:
- $1.17 per serving
- About $0.58 per capsule
- 1000 mg Glycine per serving
- 500 mg NAC per serving
- 1500 mg total active ingredients per serving
Subscription pricing is also available at $33.25 per bottle for a 1-month supply, based on the current Subscribe & Save option.
That breaks down to about $1.11 per serving on subscription.
Price matters, but the best NAC supplement or best glycine supplement should not be judged by price alone. A better comparison looks at dose, ingredient pairing, testing, manufacturing standards, serving size, and brand transparency.
A cheaper NAC supplement may look appealing at first. But if the dose is unclear, testing details are limited, or glycine is missing, it may not offer the same formula focus as a GlyNAC product.
How to Take Omre Glycine + NAC
Take 2 capsules in the morning with food.
Simple routine:
- Take 2 capsules daily
- Take with food
- Use consistently
- Store in a cool, dry place
- Speak with your healthcare professional if you take medication or manage a medical condition
Some customers mention sleep, energy, or recovery benefits in reviews, but results can vary. Supplements work best when paired with the basics too: sleep, protein, movement, hydration, and a balanced diet. Boring advice, yes. Still true.
Why Omre Combines Glycine and NAC
Glycine and NAC are different nutrients, but they work well together in a cell defense formula.
Glycine is an amino acid involved in protein production, collagen formation, nervous system signaling, and glutathione production.
NAC, short for N-Acetyl L-Cysteine, provides cysteine. Cysteine is one of the key amino acids needed to make glutathione.
Glutathione is made from three amino acids:
NAC helps provide cysteine, while glycine helps provide another key building block. That is why the combination is commonly called GlyNAC.
Human GlyNAC research in older adults has been led in part by Dr. Rajagopal Sekhar and colleagues at Baylor College of Medicine. Their studies have looked at GlyNAC supplementation for glutathione status, oxidative stress, mitochondrial function, inflammation, physical function, and other aging-related markers. These findings are promising, but research is still developing and does not mean GlyNAC treats or prevents disease (1, 2).
Omre keeps the formula simple:
- 1000 mg Glycine for glutathione precursor and cellular support
- 500 mg NAC for cysteine support and antioxidant defense
- No hidden proprietary blend
- Clear active ingredient amounts
About the Dose
Clinical GlyNAC studies in older adults have used higher doses than most daily supplement formulas, with dosing based on body weight. Omre Glycine + NAC provides 1000 mg Glycine and 500 mg NAC per serving, so it should not be presented as equal to the dosing used in those clinical trials.
This formula is designed as a daily baseline support supplement for adults who want glycine and NAC together in a simple 2-capsule serving. The goal is to support glutathione precursor intake, antioxidant defense, and cellular health as part of a healthy routine, not to copy a clinical trial protocol or claim the same outcomes.
GlyNAC vs Glutathione Supplements
Glutathione supplements and GlyNAC supplements are not the same.
Glutathione supplements provide glutathione directly. GlyNAC supplements provide two building blocks the body uses to make glutathione.
This difference matters because glutathione is a larger molecule, and supplement absorption can vary by form. Glycine + NAC takes a precursor-support approach instead of only adding glutathione directly.
Another reason people compare GlyNAC with glutathione is self-regulation. Direct glutathione supplements provide glutathione from the outside. GlyNAC provides precursor nutrients, allowing the body to make glutathione through its own production pathway. This may be a more natural fit for people who want to support glutathione availability without only relying on direct glutathione intake.
Glutathione also helps recycle other antioxidants, including vitamin C and vitamin E, after they have been used against oxidative stress. That is one reason it is sometimes called a central antioxidant in the body’s defense network.
A glutathione supplement may still make sense for some people. But for shoppers looking to support the body’s natural glutathione production, a GlyNAC supplement is a more relevant comparison.
Omre Glycine + NAC is built around that idea: give the body glycine and NAC together, in clear doses, with third-party testing and a simple daily routine.
NAC Supplement vs Glycine Supplement
NAC and glycine are both useful nutrients, but they support the body in different ways.
NAC, short for N-Acetyl L-Cysteine, is best known for its role in glutathione support. It helps provide cysteine, one of the amino acids the body uses to make glutathione. That is why NAC supplements are commonly used in formulas focused on antioxidant defense, oxidative stress balance, and cellular protection (3).
NAC is also well known for its role in respiratory health research. In medical settings, NAC has been studied for mucus clearance and lung-related support because it can affect mucus thickness and antioxidant activity. Omre Glycine + NAC is not intended to treat respiratory conditions, but this background helps explain why many people recognize NAC beyond the healthy aging space.
Glycine is a small amino acid with many jobs. The body uses it for protein structure, collagen formation, nervous system signaling, and glutathione production. Human studies have also looked at glycine for sleep quality and daytime fatigue, with some research using 3 grams before bedtime (4).
Glycine also has two well-known roles outside glutathione support. First, it acts as a calming neurotransmitter in the central nervous system, which is one reason researchers have studied glycine for sleep quality and next-day fatigue. Second, glycine is a major structural amino acid in collagen, the protein that helps support skin, joints, tendons, and connective tissue. That makes glycine relevant for people comparing supplements for sleep, recovery, skin, and healthy aging.
The simple difference is this: NAC helps supply cysteine, while glycine supplies another key building block for glutathione. On their own, each one can be useful. Together, they make a more complete glutathione precursor formula.
That is why Omre Glycine + NAC includes both in one serving:
- 1000 mg Glycine
- 500 mg N-Acetyl L-Cysteine, NAC
- 1500 mg total active ingredients per serving
This makes the formula a good fit for people who want antioxidant support, cellular health support, and daily glutathione precursor support in one simple supplement.
Omre vs Other Glycine + NAC Supplements
Many Glycine + NAC supplements look similar at first glance, but the details can differ.
When comparing products, check:
- How much glycine is included per serving?
- How much NAC is included per serving?
- Are both ingredients listed clearly?
- Is the serving size easy to understand?
- Is the product third-party tested?
- Does the brand test for heavy metals and microbes?
- Is it made in GMP-certified facilities?
- Are safety details easy to find?
- Is there a refund policy?
Omre Glycine + NAC provides 1000 mg Glycine and 500 mg NAC per serving. It is third-party tested for dose, purity, bacteria, fungus, and heavy metals, and it is made in the USA in GMP-certified facilities.
Omre does not need to claim it is the number one NAC supplement or the number one glycine supplement. The better point is simpler: the formula is clear, tested, and built around two ingredients that make sense together.
Why Omre Is Worth Comparing With Top NAC Supplements
Omre Glycine + NAC is worth comparing with top NAC supplements because it does not rely on NAC alone.
A standard NAC supplement may only provide NAC. Omre adds glycine because glutathione production depends on more than one building block.
That gives shoppers a more complete GlyNAC-style formula in one bottle:
- NAC for cysteine support
- Glycine for another glutathione building block
- 1500 mg total active ingredients per serving
- Third-party testing
- Clear label amounts
- Made in the USA
For people comparing the best NAC supplement for glutathione support, Omre is a strong option to review because it includes both NAC and glycine in one daily formula.
Why Omre Is Worth Comparing With Top Glycine Supplements
Omre Glycine + NAC is also worth comparing with top glycine supplements because it gives you more than glycine alone.
A plain glycine supplement may be useful if you only want glycine. But if your goal is glutathione support, antioxidant defense, and cellular health, the addition of NAC may make the formula more relevant.
Each serving gives you:
- 1000 mg Glycine
- 500 mg NAC
- Cell defense support
- Antioxidant support
- Glutathione precursor support
That makes Omre a good fit for shoppers who want a best glycine supplement comparison but also care about NAC, glutathione, and healthy aging support.

From Omre
Why We Started Omre
Omre was founded by Dr. Pedram Kordrostami with a clear goal: make supplements that use thoughtful formulas, research-backed doses, and ingredients that fit real health routines.
The supplement shelf can get noisy fast. Some products chase trends. Some hide weak doses inside long blends. Omre takes a cleaner route by focusing on ingredient quality, testing, and clear formulas.
Our Formulation Philosophy
Omre Glycine + NAC was built around a simple idea: glutathione support works best when the formula gives the body useful building blocks.
That is why each serving includes 1000 mg Glycine and 500 mg NAC. The goal is not to make a loud label. The goal is to make a daily GlyNAC formula that is easy to understand and easy to compare.
Our Quality Promise
Omre Glycine + NAC is third-party tested every batch, not just tested once during development. Each batch is tested for active ingredient levels, purity, heavy metals, and microbial safety.
Testing is completed at the capsule level, and the full 2-capsule serving provides 1000 mg Glycine and 500 mg NAC.
The Omre Difference
Omre does not use a hidden proprietary blend in this formula. Each key ingredient amount is listed clearly.
That matters because two NAC supplements or glycine supplements can look similar online but offer very different doses, testing standards, and ingredient quality.
How to Choose a GlyNAC Supplement
GlyNAC supplements can look simple, but the label still deserves a closer look.
Before buying, check:
- Does it include both glycine and NAC?
- How much glycine is in each serving?
- How much NAC is in each serving?
- Are the active ingredient amounts clearly listed?
- Is the product third-party tested?
- Is it tested for heavy metals and microbes?
- Is it made in GMP-certified facilities?
- Are directions and safety warnings easy to find?
- Is there a refund policy?
A strong GlyNAC supplement should make comparison easy. You should not have to guess the dose, ingredient purpose, or testing standards.
Omre Glycine + NAC was made for people who want 1000 mg Glycine, 500 mg NAC, third-party testing, and a clean daily formula for glutathione and antioxidant support.
