Quick Answer
It can. Stomach acid production often declines with age, gut function changes, and common medications can interfere with the uptake of specific nutrients. This is one reason delivery format is discussed more often for adults over 50 — when baseline absorption may already be reduced, the efficiency of delivery can matter more.
What changes, and why
Aging doesn't mean you can't absorb nutrients — but several shifts can reduce uptake of specific ones:
- Lower stomach acid can reduce absorption of nutrients like vitamin B12, iron, and calcium that depend on an acidic environment.
- Gut changes over time can affect how efficiently the intestinal wall takes up nutrients.
- Common medications — including some for acid reflux and other conditions — can interfere with specific nutrients.
Why delivery format matters more with age: the same nutrient, in a better-delivered form, may make a larger practical difference for someone whose baseline absorption has declined than for a 25-year-old with a robust digestive system. That's the honest case for absorption-focused products in an older audience.
None of this is a reason to assume a problem. If you're concerned about a specific deficiency, a physician can test for it — which beats guessing from a label. Questions about B12, vitamin D, or iron status in particular are worth raising at a check-up.

Related Questions
Do older adults need different supplements?
Not necessarily different supplements, but the nutrients most affected by age-related absorption changes — like B12 and vitamin D — are worth paying attention to, ideally guided by testing.
Does better absorption technology help older adults more?
Potentially, for the nutrients whose absorption declines with age. When baseline absorption is lower, delivery efficiency can matter more — though individual circumstances vary.
