When you think about essential minerals for staying healthy as you age, calcium and vitamin D often steal the spotlight.

But there’s another important player working behind the scenes—phosphorus.

This mineral helps keep your bones strong, your energy levels steady, and your cells running smoothly.


And while it may not get as much attention, phosphorus plays a crucial role in your overall health.

That said, before you consider reaching for a supplement, it’s important to understand what phosphorus does, where you naturally get it from, and why taking extra could actually do more harm than good.


What does phosphorus do for your body?

Phosphorus is the second most abundant mineral in the body—right after calcium.

Around 85% of it is stored in your bones and teeth, helping to maintain strength and structure.

But that’s just the beginning.

Phosphorus also:

• Supports muscle and nerve function
• Helps regulate blood pH
• Plays a key role in making DNA and RNA
• Produces ATP, the molecule your body uses for energy

How do we get phosphorus?

Good news: most people already get enough phosphorus just by eating a balanced diet.

You’ll find it in many everyday foods, especially protein-rich ones like:

• Chicken, beef, pork, and fish
• Eggs and dairy products
• Nuts, seeds, and legumes
• Whole grains and bran cereals
• Some fruits and vegetables like potatoes, bananas, and avocados

Here’s a quick snapshot:

• 1 cup of milk = 226 mg of phosphorus
• 3 oz of salmon = 214 mg
• ½ cup of lentils = 178 mg

The recommended daily intake for adults is 700 mg—and most people hit that easily without trying.

The hidden source: phosphorus additives

While natural foods are a great source of phosphorus, processed foods can push your intake too high.

Many packaged products—especially sodas, processed meats, and baked goods—contain phosphorus additives that help preserve freshness and improve texture.

Look for ingredients like “phosphate” or “phosphoric acid” on labels.

These additives are more easily absorbed by the body, which means your phosphorus levels can quickly go above what’s healthy—without you even realizing it.

Should you take a phosphorus supplement?

For most healthy adults, the answer is no.

Phosphorus deficiency is rare, and taking extra without medical guidance can actually harm your health.

However, in certain situations, supplements might be necessary—such as:

• If you follow a very restricted diet (like strict veganism)
• If you’ve experienced significant trauma, burns, or recent surgery
• If you take medications that deplete phosphorus
• If you have a medical condition that affects how your body absorbs or loses minerals

In any of these cases, a doctor may recommend supplements—but never start one on your own.

What are the risks of too much phosphorus?

Excess phosphorus can throw off your calcium balance, leading to serious issues like:

• Weakened bones or osteoporosis
• Calcium buildup in your blood vessels and organs
• Increased risk of heart disease

This is especially dangerous for people with kidney disease, whose bodies can’t easily remove extra phosphorus.

Tips for keeping your phosphorus levels in balance

• Stick to whole foods: Lean proteins, dairy, legumes, and grains are your best sources.
• Avoid processed foods: Watch out for added phosphorus in packaged items.
• Drink enough water: Good hydration supports kidney function.
• Check with your doctor: If you have kidney issues or take medications that affect mineral levels, a healthcare provider can guide you.

What seniors should know

As you age, kidney function naturally declines, and your body may process minerals differently.

That’s why it’s extra important for older adults to keep an eye on their phosphorus intake.

Too much can affect bone and heart health—two key concerns in later life.

If you’re worried or curious, ask your doctor for a blood test to check your phosphorus and calcium levels before starting any supplement!
