As we age, our bodies absorb nutrients less efficiently, which can lead to deficiencies even with a healthy diet. Here's why this happens and how to address it:
- Reduced Stomach Acid: Lower acid levels make it harder to absorb key nutrients like vitamin B12, iron, and calcium.
- Gut Bacteria Changes: Aging alters gut microbiome balance, reducing nutrient synthesis and absorption.
- Nutrient Competition: Some nutrients, like calcium and iron, compete for absorption, making timing and pairing important.
- Weakened Transport Systems: Aging decreases the efficiency of nutrient transporters in the intestines.
- Cellular Decline: Slower autophagy (cell cleanup) reduces nutrient recycling.
Quick Tips to Improve Absorption
- Pair vitamin C with iron-rich foods for better absorption.
- Avoid calcium with iron supplements.
- Incorporate fermented foods and healthy fats into meals.
- Consider supplements designed for aging adults.
Aging impacts digestion, but with dietary adjustments and targeted supplementation, you can support your body's changing needs.
Understanding the Aging Process: How Aging Affects Your ...
Age-Related Changes in Digestion
As we age, our digestive system becomes less efficient, making it harder to process and absorb nutrients. These changes impact everything from breaking down food to transporting nutrients through the intestinal wall. Below, we’ll explore how reduced stomach acid and shifts in gut bacteria contribute to these challenges.
Reduced Stomach Acid and Enzyme Production
Older adults often produce less stomach acid, which plays a crucial role in nutrient absorption. For example, low acid levels can keep vitamin B12 bound to proteins, prevent iron from converting into an absorbable form, and make it harder for calcium to dissolve. This means fewer nutrients are available for the body to use, even when eating a balanced diet.
Over time, this decline in acid production can lead to deficiencies in essential nutrients, highlighting the importance of targeted supplementation.
Changes in Gut Bacteria
Aging also disrupts the balance of gut bacteria, which further complicates nutrient absorption. The composition of the gut microbiome shifts, reducing beneficial bacteria that help synthesize nutrients like vitamin K and certain B vitamins. These changes can also lower the production of short-chain fatty acids, decrease mineral absorption, and weaken the intestinal lining.
To address these digestive changes, MASI Longevity Science creates supplements with highly absorbable nutrient forms, designed to support aging digestive systems effectively.
How Nutrients Compete and Block Each Other
As we age, the body becomes less efficient at absorbing nutrients. One reason for this is that nutrients often have to share the same pathways for absorption. This competition can make it harder for the body to get what it needs, adding to the digestive issues that come with aging. Let’s break down how specific nutrients interfere with one another and how aging impacts nutrient transport.
Nutrients That Interfere With Each Other
Some nutrients compete for the same absorption pathways, which can limit how much the body takes in when they’re consumed together. For example, research shows that consuming high amounts of calcium can reduce iron absorption. Similarly, an imbalance between zinc and copper can affect how well they’re absorbed. Paying attention to meal timing and ensuring a balanced intake of nutrients can help improve absorption.
Reduced Nutrient Transport Systems
Aging doesn’t just affect competition between nutrients - it also impacts the body’s ability to transport them. As we grow older, the number and efficiency of intestinal transporters decline. This is especially true for minerals that rely on these carriers to be absorbed effectively. So, the natural aging process can make it even harder for the body to get essential nutrients.

Cell-Level Changes in Aging
As we get older, our cells change how they process nutrients. One key shift is in the efficiency of autophagy - the body’s built-in system for breaking down and reusing old or damaged components.
Cell Cleanup and Nutrient Recycling
Aging slows down autophagy. This slowdown causes waste to build up, reduces nutrient recycling, and weakens cellular function. Studies show that improving cellular cleanup can boost nutrient recycling. Certain compounds, like Spermidine and Fisetin, help activate autophagy and clear out aging cells, making nutrient processing more efficient.
How to Support Autophagy
- Eat a balanced, nutrient-dense diet
- Stay active with regular exercise
- Try time-restricted eating
- Consider supplements that promote cellular cleanup
Understanding these cellular changes underscores the importance of maintaining autophagy. Simple lifestyle changes and targeted supplements can help improve nutrient absorption and overall cellular health.
Ways to Improve Nutrient Absorption
Choosing the Right Supplements
As we get older, selecting the right supplements becomes more important. For adults over 40, the timing and form of supplements can play a big role in how well nutrients are absorbed. For instance, fat-soluble nutrients like Resveratrol are best taken with meals that include healthy fats.
MASI Longevity Science tackles these absorption challenges by using pharmaceutical-grade ingredients sourced from Germany. Their supplements undergo independent testing in Switzerland to ensure purity and effectiveness. They also provide age-based dosing recommendations:
- Ages 40–50: 1 capsule daily
- Ages 50 and older: 2 capsules daily
In addition to high-quality supplements, making smart dietary changes can further improve how your body absorbs nutrients.
Diet Changes That Help Absorption
Tweaking your diet can also make a big difference in nutrient uptake. Here are some practical strategies:
Meal Timing and Composition
- Space out meals to allow for proper digestion.
- Include healthy fats to help your body absorb fat-soluble nutrients.
- Pair vitamin C-rich foods with iron to improve iron absorption.
- Limit caffeine intake around iron-rich meals, as it can reduce absorption.
Food Preparation Tips
- Use gentle cooking methods, like steaming vegetables, to keep nutrients intact.
- Soak grains and legumes before cooking to make them easier to digest.
- Add fermented foods to your diet - they may improve nutrient availability.
- Chop or crush garlic shortly before cooking to activate its beneficial properties.
Smart Food Pairings
- Match nutrient-dense foods wisely. For example, pair iron-rich foods with vitamin C sources to enhance absorption.
- Aim for balanced meals that include proteins, healthy fats, and carbohydrates.
- Avoid eating calcium-rich foods alongside iron supplements, as calcium can block iron absorption.
Conclusion
Aging significantly impacts how our bodies absorb nutrients, influencing overall health. Factors like reduced enzyme production, shifts in gut bacteria, and changes in cellular absorption all play a role in this process.
Overcoming these challenges requires both dietary changes and supplements that are carefully designed. The effectiveness of these supplements depends on their form, quality, and how well the body can absorb them. This highlights the importance of using products backed by scientific research.
