Digestive enzymes are essential for breaking down food into nutrients your body can absorb. As you age, especially after 40, enzyme production naturally decreases, making nutrient absorption less efficient. This can impact how your body processes proteins, fats, carbohydrates, and even supplements.
Here’s what you need to know:
-
Main Enzymes and Functions:
- Amylases: Break down carbohydrates into sugars.
- Proteases: Break down proteins into amino acids.
- Lipases: Help digest fats with the assistance of bile.
- Nucleases: Process DNA and RNA into nucleotides.
-
Key Factors Affecting Enzyme Activity:
- pH Levels: Each enzyme works best in a specific pH range (e.g., stomach enzymes like pepsin need a highly acidic environment).
- Age: Enzyme production declines with age, reducing nutrient absorption.
- Supplements: Products like NMN, Resveratrol, Spermidine, and Fisetin are designed to counteract these changes.
-
How Nutrients Are Absorbed:
After enzymes break down food, nutrients are absorbed through the intestinal wall using methods like passive diffusion, active transport, or facilitated diffusion.
To address age-related declines, supplements tailored for enzyme efficiency, like those from MASI Longevity Science, can support better nutrient absorption. MASI products are rigorously tested, free from common allergens, and designed with specific dosing for individuals over 40.

How Nutrients Are Digested
Digestion is a mix of mechanical and chemical processes, with enzymes playing key roles at every stage. Here's a closer look at how enzymes work throughout digestion.
Main Digestion Steps
Digestion begins in the mouth, where chewing and salivary amylase start breaking down starches. In the stomach, proteins are targeted by pepsin, which is activated in the stomach's acidic environment (pH 1.5–3.5).
In the small intestine, pancreatic enzymes and bile work together to process starches, proteins, and fats. Intestinal enzymes then complete the breakdown of nutrients.
| Digestive Location | Primary Enzymes | Main Function | Optimal pH |
|---|---|---|---|
| Mouth | Salivary Amylase | Starch breakdown | 6.7–7.0 |
| Stomach | Pepsin | Protein digestion | 1.5–3.5 |
| Small Intestine | Pancreatic Amylase, Lipase, Proteases | Breakdown of various nutrients | 6.0–7.4 |
Each enzyme operates within specific conditions, ensuring nutrients are broken down effectively.
Types of Nutrients Broken Down by Enzymes
Different enzymes target specific nutrient types:
- Carbohydrates: Amylases convert complex starches into simple sugars like glucose, fructose, and galactose.
- Proteins: Proteases break down proteins into amino acids or smaller peptides.
- Lipids: Lipases, with help from bile salts, break triglycerides into fatty acids and glycerol. Bile emulsifies fats into smaller droplets, making them easier to digest.
- Nucleic Acids: Nucleases process DNA and RNA into nucleotides, which are further simplified for cellular use.
Understanding these processes is key to improving nutrient absorption, a priority in MASI's supplement development. These enzyme-driven steps ensure nutrients are fully prepared for absorption.
Main Digestive Enzymes and Their Functions
Categories of Digestive Enzymes
The digestive system relies on four main enzyme groups, each designed to target specific nutrient types. These enzymes work together to break down complex molecules into forms the body can absorb:
| Enzyme Group | Primary Role | Examples | Where They Act |
|---|---|---|---|
| Carbohydrases | Break down carbohydrates | Alpha-amylase, Maltase, Lactase | Mouth, Small intestine |
| Proteases | Break down proteins | Pepsin, Trypsin, Chymotrypsin | Stomach, Small intestine |
| Lipases | Break down fats | Pancreatic lipase, Gastric lipase | Stomach, Small intestine |
| Nucleases | Break down nucleic acids | DNase, RNase | Small intestine |
How Enzymes Start Working
To function properly, digestive enzymes are secreted in inactive forms called zymogens (like pepsinogen). These zymogens activate under specific pH conditions. Once active, enzymes use a lock-and-key mechanism to bind to their target molecules. This process lowers the energy required for reactions, speeding up nutrient breakdown. This precise action is essential for the body to absorb nutrients effectively.
pH Effects on Enzymes
An enzyme’s efficiency depends heavily on the pH of its environment. Different parts of the digestive system maintain specific pH levels to ensure enzymes work at their best:
| Digestive Region | pH Range | Active Enzymes |
|---|---|---|
| Mouth | 6.7-7.0 | Salivary amylase |
| Stomach | 1.5-3.5 | Pepsin |
| Small Intestine | 6.0-7.4 | Pancreatic enzymes |
Each enzyme performs best within its ideal pH range, ensuring nutrients are broken down efficiently as they move through the digestive tract.
How Nutrients Enter the Body
Nutrient absorption relies on specific transport systems that follow enzymatic breakdown. Once broken down, nutrients enter the body either through the bloodstream or via the lymphatic system.
Ways Nutrients Are Absorbed
The intestinal wall uses three main methods to transfer nutrients from the digestive system into circulation:
| Transport Method | How It Works | Examples of Nutrients |
|---|---|---|
| Passive Diffusion | Nutrients naturally move from areas of high to low concentration | Water-soluble vitamins, short-chain fatty acids |
| Active Transport | Energy is used to move nutrients against their concentration gradients | Amino acids, glucose, minerals |
| Facilitated Diffusion | Proteins assist specific molecules in crossing cell membranes | Fructose, some amino acids |
The small intestine’s inner lining is covered with villi, which increase the surface area for absorption.
Transport Proteins for Different Nutrients
Specialized proteins regulate how nutrients enter the bloodstream:
| Nutrient Type | Transport Protein(s) | Location |
|---|---|---|
| Glucose | GLUT2, SGLT1 | Small intestine brush border |
| Amino Acids | LAT1, TAT1 | Intestinal epithelial cells |
| Fatty Acids | CD36, FATP4 | Small intestine membrane |
These proteins work in sync with other factors to ensure efficient nutrient uptake.
Improving Nutrient Absorption
Several factors influence how well nutrients are absorbed:
- Enzyme Activity: Enzymes break nutrients into absorbable forms.
- Timing: Carbohydrates are absorbed more quickly than proteins.
- Chemical Environment: A balanced pH supports absorption.
Good digestive health depends on sufficient stomach acid, proper pancreatic enzyme levels, and a healthy gut microbiome. Supplement timing also matters - fat-soluble vitamins absorb better with meals containing healthy fats, while water-soluble ones may work best on an empty stomach. Factors like age, stress, medications, and health conditions can also impact absorption efficiency.

What Affects Enzyme Function
Body Chemistry Factors
Digestive enzymes need specific chemical conditions to work effectively. Compounds like bile salts and bicarbonate play a key role in creating the right environment. Bile salts help break down fats, while bicarbonate neutralizes stomach acid, ensuring the digestive process runs smoothly.
Effects of Age and Health
As we age, our bodies produce fewer enzymes, which can make digesting nutrients harder. After 40, this decline can affect how well the body processes proteins, absorbs minerals, breaks down carbs, and metabolizes fats. Certain health issues, like gastrointestinal disorders, chronic stress, or the use of specific medications, can further disrupt enzyme function. Pancreatic insufficiency, in particular, poses a significant challenge. These factors highlight the importance of finding ways to support enzyme activity as we age.

Why is the pH in different parts of the digestive system important for enzymes to break down nutrients?
The pH levels in different regions of the digestive system are essential because enzymes require specific pH conditions to function effectively. For example, the stomach has a highly acidic environment (low pH) that activates enzymes like pepsin to break down proteins, while the small intestine is more alkaline (higher pH), which supports enzymes like lipase and amylase for fat and carbohydrate digestion.
This variation ensures that each enzyme can perform its specific role in nutrient breakdown, allowing your body to absorb essential nutrients efficiently. Without the right pH conditions, enzymes may become inactive, leading to incomplete digestion and reduced nutrient absorption.
