The Manufacturing Step Nobody Asks About
When you evaluate a supplement for your dog, you probably look at the ingredient list, maybe check the dosage, possibly research the brand. But there's a step in the process that most consumers never think about that can make the difference between an effective supplement and an expensive placebo: how it was made.
The manufacturing process, specifically how heat, moisture, and pressure are applied during production, directly affects whether the active ingredients in a supplement are still active when they reach your dog.
What Heat Does to Sensitive Ingredients
Many bioactive compounds are heat sensitive, meaning they degrade or become inactive when exposed to high temperatures during processing. This is a straightforward chemistry issue: heat provides the energy to break chemical bonds, altering the structure (and therefore the function) of complex molecules.
Ingredients particularly vulnerable to heat degradation include:
- Nicotinamide Riboside (NR): NR's molecular structure can be compromised by sustained heat exposure, reducing the amount of functional NR that reaches your dog's cells.
- Probiotics: Live organisms that are killed by temperatures above approximately 115 to 120 degrees Fahrenheit. Heat processed probiotic supplements may contain dead bacteria that provide no benefit.
- Enzymes: Proteins that lose their shape (denature) and therefore their function when heated above their stability threshold.
- Certain vitamins: Vitamin C, some B vitamins, and vitamin A can be partially or fully destroyed by heat processing.
- Omega 3 fatty acids: Can oxidize when exposed to heat, becoming rancid and potentially harmful rather than beneficial.
- Collagen peptides: While collagen itself is relatively heat stable, some studies suggest that excessive heat can alter the peptide profile, potentially affecting bioactivity.
How Freeze Drying Works
Freeze drying (lyophilization) is a dehydration process that removes water from a frozen product through sublimation (converting ice directly to water vapor without passing through a liquid phase). The process works in three stages:
- Freezing: The product is frozen to a very low temperature
- Primary drying: Under vacuum, ice is converted directly to water vapor and removed
- Secondary drying: Remaining bound water is removed at slightly higher temperatures (still well below degradation thresholds)
The key advantage: because the temperatures used throughout freeze drying remain low (well below the degradation point of most bioactive compounds), heat sensitive ingredients survive the process intact. The resulting product is shelf stable, lightweight, and retains essentially all of its original bioactivity.
How Heat Processing Works
Traditional supplement manufacturing often involves heat at various stages:
- Spray drying: Liquid ingredients are sprayed into a chamber of hot air (temperatures of 300 to 400+ degrees Fahrenheit) to rapidly evaporate water. This is fast and cheap but exposes ingredients to extreme temperatures.
- Extrusion: Common in making chewable supplements and treats. Ingredients are pushed through a heated barrel under pressure. Temperatures can reach 250 to 350 degrees Fahrenheit.
- Baking: Some chew type supplements are baked, exposing ingredients to sustained heat.
- Tablet compression: While compression itself doesn't generate extreme heat, the binding agents and coatings used often require heat application.
The Practical Impact
Let me illustrate with a hypothetical but realistic scenario. Two supplements both list 250mg of NR on the label. Both were manufactured from the same source material. One was freeze dried. One was spray dried at high temperature.
The freeze dried product may retain 90% or more of its NR in active form. The spray dried product might retain 50% or less, depending on the specific conditions. Both labels say the same thing. The actual functional content could be dramatically different.
This isn't unique to NR. The same principle applies to every heat sensitive ingredient. And because supplement labels reflect what was added during manufacturing, not what survived the manufacturing process, the label alone doesn't tell you the whole story.
How to Evaluate Manufacturing Quality
Since you can't test supplements in your kitchen, here are indicators of manufacturing quality:
- Does the company disclose its manufacturing process? Companies that use premium processes (freeze drying, cold processing) typically advertise this because it's a competitive advantage.
- Is there third party testing? Independent testing that verifies the active ingredient content at the time of purchase (not just at manufacture) helps confirm that what's on the label is actually in the product.
- What form is the supplement? Powders and capsules are generally exposed to less processing heat than chews and treats. Freeze dried powders are among the best preserved forms.
- How is it packaged? Light, moisture, and oxygen all degrade certain ingredients over time. Quality packaging (opaque containers, moisture barriers, nitrogen flushing) protects the product post manufacture.
- Storage recommendations? Products that require refrigeration or cool storage after opening are often more bioactive (because they're acknowledging ingredient sensitivity) but less convenient.
Why This Matters for Your Dog
You're investing time and money in your dog's supplement routine because you care about their health. You deserve to know that the ingredients you're paying for are actually functional when they reach your dog. A cheaper supplement that has been heat degraded into partial inactivity isn't actually cheaper. It's just less effective per dollar.
When evaluating products like LongTails (which uses freeze dried processing to preserve its NR, collagen, bone broth, and beef liver components) or any other supplement, ask about the manufacturing process. It's the question that separates informed consumers from hopeful ones. And your dog's cells can tell the difference even if the labels can't.
