- Vitamin D, B12, calcium, protein, fiber and fluids are common topics after 70.
- Food intake, medications and health conditions can change nutrient needs.
- Supplements should be reviewed for interactions and dose safety.
Why nutrient needs can change
Appetite, chewing problems, digestion, medications, kidney function and lower activity can affect nutrition after 70.
Regular weight changes, fatigue or weakness should be discussed rather than dismissed as normal aging.
Vitamin D and calcium
Vitamin D and calcium support bone health, but the right amount depends on diet, sun exposure, kidney health and fracture risk.
Too much supplementation can cause problems, so dosing should be reviewed.
Vitamin B12
Some older adults have reduced ability to absorb vitamin B12, especially with certain stomach conditions or medications.
Low B12 can contribute to anemia, nerve symptoms or cognitive changes, but testing and treatment should be handled medically.
Protein
Protein supports muscle maintenance, wound healing and recovery. Needs can vary with kidney disease, activity level and illness.
Spreading protein across meals may be easier than relying on one large meal.
Fiber and hydration
Fiber supports digestive health and may help with cholesterol and blood sugar patterns. Increase fiber gradually and pair it with fluids when appropriate.
Older adults may feel less thirst, so hydration routines can be helpful, especially in warm weather or illness.
Supplement safety
Supplements can interact with blood thinners, diabetes medications, blood pressure medicines and other treatments.
Bring all vitamins, minerals, herbs and over-the-counter products to appointments for review.
Ask a clinician before starting supplements, especially with kidney disease, blood thinners, cancer treatment, diabetes medication or multiple prescriptions.
Frequently asked questions
