Product Description

Glutathione Softgel Manufacturing | Reduced L-Glutathione Stability Solutions

Your Glutathione product lost potency after 6 months on the shelf. The problem isn't the formula—it's the form of glutathione you chose.

Most brands don't realize there are two forms of glutathione: reduced (L-GSH) and oxidized (GSSG). Only reduced L-Glutathione delivers antioxidant support. Oxidized glutathione is essentially "spent"—already bonded with other molecules and no longer biologically active.

The challenge? Reduced L-Glutathione degrades rapidly when exposed to oxygen, light, or heat. A poorly manufactured softgel can lose 30-50% of its active glutathione within the first 3 months.

At Runxin Biotechnology, we understand this challenge. Our 6000+ formula library includes 127 Glutathione-based formulations, with stability data on each batch going back 5 years. We've learned what works—and what causes products to fail.

What Makes Our Glutathione Softgel Different

Reduced Form Only

We use exclusively reduced L-Glutathione in our formulations. This isn't the default choice in the industry—many manufacturers use unspecified or mixed glutathione forms to cut costs. Reduced L-GSH is the only form your body can directly utilize for antioxidant support.

Inert Atmosphere Processing

Oxygen exposure is the primary killer of glutathione potency. Our production lines feature nitrogen-blanketed environments throughout the encapsulation process:

  • Raw material handling under inert gas
  • Encapsulation in oxygen-controlled chambers
  • Immediate sealing in airtight packaging

Result: Our Glutathione softgels maintain 95%+ of labeled potency through the entire shelf life.

Stability-Verified Formulations

Every Glutathione formula in our library has passed real-time stability testing. We don't guess at compatibility—we have data. Our QC records show:

  • 127 Glutathione-specific formulations developed
  • 98.2% first-time production success rate
  • Average potency retention: 97.3% at 24 months

Third-Party Testing

Each batch undergoes independent laboratory verification for:

  • Glutathione content (HPLC method)
  • Oxidized glutathione (GSSG) levels
  • Dissolution rate
  • Heavy metal screening

Customization Options

Dosage: 50mg, 100mg, 200mg, 250mg, 300mg, 500mg per softgel (custom strengths available)

Shell Options:

  • Bovine gelatin (clear or colored)
  • Porcine gelatin
  • Fish gelatin
  • Vegetarian pullulan capsule

Appearance:

  • Custom printing on softgel surface

Packaging:

  • Bottles (30/60/90/120 softgels)

  • Alpha-Lipoic Acid
  • N-Acetyl Cysteine (NAC)

Frequently Asked Questions

Q: What's the difference between reduced glutathione and oxidized glutathione? Why does it matter?

Reduced L-Glutathione (L-GSH) is the active, "ready-to-use" form your body needs for antioxidant defense. Oxidized glutathione (GSSG) has already donated its electrons—it's the "spent" form that needs to be recycled by your body before it can work again.

For supplement efficacy, reduced L-GSH is the only meaningful choice. Many manufacturers don't specify which form they use, or use oxidized glutathione to reduce costs. We specify reduced L-Glutathione on every label.

Q: How do you ensure the Glutathione remains active in your softgels?

Three key factors:

1.Inert atmosphere production - Our entire manufacturing process (from raw material handling to encapsulation) occurs under nitrogen protection. Oxygen is the enemy of reduced glutathione.

2.Stable matrix formulation - We select complementary ingredients and excipients that protect glutathione from degradation. This isn't accidental—it's based on 5+ years of stability data.

3.Airtight packaging - We use high-barrier packaging materials and recommend nitrogen-flushed bottles for premium formulations.

The proof: We guarantee 90%+ of labeled glutathione content at the end of shelf life, backed by third-party testing.

Q: Can Glutathione be combined with Vitamin C in the same softgel?

Yes—and this combination is scientifically synergistic. Vitamin C helps regenerate oxidized glutathione back to its active reduced form. Many of our clients request this combination.

The technical challenge: Vitamin C can accelerate glutathione oxidation if formulated incorrectly. Our R&D team has solved this with a proprietary stabilization matrix. We have 23 successful Glutathione + Vitamin C formulas in our library.

Q: What is the shelf life of your Glutathione softgels? How should they be stored?

Standard formulations: 24 months shelf life.

With our premium stability package: Up to 36 months.

Storage recommendations:

  • Keep in original, tightly sealed container
  • Store in cool, dry place (15-25°C ideal)
  • Avoid exposure to direct sunlight or high humidity
  • Do not freeze

Q: Do you offer vegetarian Glutathione softgels?

Yes. We use pullulan (plant-based) capsules for vegetarian formulations. The same stability considerations apply—our vegetarian Glutathione capsules undergo identical inert-atmosphere processing and stability testing.
