Thorne provides standalone NAC at 500 mg per capsule. Omre combines NAC with glycine to support antioxidant pathways through a dual-amino approach.

Brand Backgrounds at a Glance

Both brands position themselves around science and long-term health. Their approaches, however, are slightly different.

Thorne

Thorne is a science-focused wellness company with a long-standing presence in the supplement space. The brand emphasizes personalized testing, data-driven health strategies, and supporting health span over time.

Their portfolio includes a wide range of products, from single-ingredient nutrients to more complex formulas. This appeals to users who prefer to build their own supplement routine piece by piece.

For someone looking for a straightforward NAC product with flexible dosing, Thorne’s approach fits well. It allows users to stack NAC with other supplements based on their own preferences.

Omre

At Omre, we are a doctor-founded brand led by Dr. Pedram Kordrostami. Our philosophy is research-first and clarity-driven. We design supplements around clinically aligned dosing and long-term daily use, not trends or extreme potency.

Our Glycine + NAC formula was created to support cellular health and antioxidant balance in a structured way. We list exact ingredient amounts. We do not use proprietary blends. Everything is clearly labeled, so you know what you are taking each day.

We focus on a predictable daily structure. By combining glycine and NAC, we align the formula with how these amino acids are commonly discussed together in antioxidant and glutathione-related research.

Ingredient and Dosing Strategy Comparison

Both products provide 500 mg of NAC per serving. The key difference is that Omre pairs NAC with glycine as part of a combined daily strategy.

Omre Glycine + NAC

Omre provides a dual amino formula designed for daily use. The structure is consistent and pre-built, rather than requiring separate products.

Here is the full daily structure:

• 1,000 mg glycine per serving

• 500 mg N-Acetyl-L-Cysteine per serving

• Two capsules daily

• Vegetarian capsules

• Free from gluten, dairy, soy, artificial colors, preservatives, and flavors

• Third-party lab tested

• GMP-compliant USA manufacturing

NAC is widely used as a precursor to glutathione, one of the body’s key antioxidants (1). Glycine is also involved in glutathione production (2). Research has reported that both amino acids play roles in supporting oxidative balance as part of normal physiology. 

Because glutathione is made from glycine, cysteine, and glutamate, these ingredients are often discussed together in antioxidant research.

Our goal was not to increase dosage beyond common ranges, but to create a balanced, predictable structure suitable for daily use.

Thorne NAC

Thorne offers a single-ingredient NAC formula. This gives users the flexibility to adjust intake or combine it with other nutrients separately.

Here is the structure:

• 500 mg N-Acetyl-L-Cysteine per capsule

• Single ingredient formula

• 90 capsules per bottle

• Hypromellose capsule

• Includes leucine and silicon dioxide

• Flexible dosing of 2 to 3 capsules daily, depending on routine

Because it is a standalone NAC, users can choose how much to take and whether to pair it with glycine or other nutrients on their own. This approach may appeal to those who prefer building a custom stack rather than using a combined formula.

Transparency, Testing, and Manufacturing

With amino acid supplements, sourcing and manufacturing standards matter. Purity, correct dosing, and quality control are important for long-term use.

Omre

Omre is a doctor-founded brand focused on clarity and research-aligned formulation.

• Doctor-founded and research-backed

• Third-party lab tested

• Manufactured in GMP-compliant facilities in the USA

• No synthetic fillers or binders

• Transparent ingredient amounts are listed clearly

Thorne

Thorne positions itself as a science-driven wellness company with an emphasis on quality and personalization.

• Science-focused brand positioning

• Third-party lab tested

• Established supplement manufacturer

• Capsule form with clearly listed dosage

• Emphasis on personalized wellness solutions

Pricing and Value Comparison

Price is often part of the decision, especially for supplements used daily.

Thorne NAC

• $33 per bottle

• 90 capsules

• 500 mg per capsule

• Suggested 2 to 3 capsules daily

At one capsule daily, the bottle lasts 90 days. At three capsules daily, it lasts 30 days. The monthly cost depends on how much NAC you choose to take.

Omre Glycine + NAC

• $35 per bottle

• 30 servings

• 1,000 mg glycine + 500 mg NAC per serving

• Two capsules daily

• Structured daily dosing

Each serving provides both NAC and glycine at the listed amounts. The price reflects a dual-ingredient formula rather than NAC alone.

Both options fall within a similar general price range, but they differ in formulation strategy. One offers flexibility with NAC only. The other provides a built-in combination designed for daily cellular support.

Thorne NAC vs Omre Glycine + NAC: Which Is Better?

Our Omre Glycine + NAC was designed as a structured, dual amino formula for daily cellular support. Instead of offering NAC on its own, we paired 500 mg of NAC with 1,000 mg of glycine in one consistent serving. This reflects how these amino acids are often discussed together in research around glutathione and oxidative balance.

The dosing is steady and predictable. Two capsules provide a clearly defined daily structure, without the need to calculate or stack separate products. For adults looking for a simple routine built around research-aligned amounts, this approach can feel straightforward and practical.

That said, Thorne is a strong option for those who prefer standalone NAC. Because it offers 500 mg per capsule with flexible intake of 2 to 3 capsules daily, users can adjust their dose or combine NAC with other nutrients as they see fit. 

For someone who already has a supplement stack and wants to add NAC specifically, that flexibility may be appealing.

The difference is not about one being extreme or dramatic. It comes down to structure. Thorne offers single-ingredient flexibility. Omre offers a built-in pairing designed for daily use and long-term consistency.

Final Words

Both Thorne NAC and Omre Glycine + NAC are quality supplements with clearly listed ingredient amounts.

Thorne may suit those who want a straightforward, single-ingredient NAC product that can be adjusted or combined with other nutrients.

Omre may suit those looking for a combined NAC and glycine formula designed for structured, everyday cellular support.

If you are looking for a structured, dual-ingredient formula designed for steady antioxidant support, our Omre Glycine + NAC was formulated to keep things clear, measurable, and dependable.
