Vitamins for nail health: Tips on creating a vitamin plan to support healthy nails

11 Dec 2021

Whilst nail aesthetics have become an element of a beauty ritual for many, their functional role in health and wellbeing is often forgotten about. Nails protect the skin on your toes and fingers, as well as helping you perform basic activities such as scratching a surface or holding an item more tightly.

Vitamin plan

But did you know, nails are an indicator of health in the body? Any unusual characteristics of certain parts of the nail may mean something’s going on inside the body. These unusual characteristics show up as nail discoloration, unevenness, and brittleness (1). Other factors such as extreme weather can also cause nails to be brittle and split (2).

To help maintain nail health, we need to be conscious of how we can take care of them from the inside out. Aside from clipping nails properly, moisturising, and practicing proper hygiene (1), it’s also good to support nail health from the inside. Nutrients provide the body with what it needs to minimise deficiencies and boost bodily functions to prevent illnesses and infections. Here are some tips on how to make a vitamin plan for your nails.

Make an assessment of your body

The first step to maintaining nail health is to conduct your own assessment. Do you see any unusual growth, colour, or structure in your nails (3)? Do they crack or chip more often, or are they sensitive to touch in certain parts? Answering these questions may point out what your body is experiencing.

If these symptoms are present, speak to your healthcare professional to help understand their causes and impacts, as well as work out next steps. This is particularly important if symptoms persist, and you require additional tests to confirm your condition.

Get to know some of the nutrients for nail health

After the assessment, it’s good to know what possible actions you can do to support healthy nails. Adding exercise and a proper diet are some of the basic steps which can kickstart your healthy lifestyle. For your vitamin plan, it’s about choosing the nutrients that help support nail health.

Some of the sources of vitamins and minerals that help nail health are iron, cranberry, collagen, and biotin. Let's look at the science behind these nutrients to understand why they’re good for your nails:


Iron is an essential mineral for various functions like energy production, oxygen transport, and others (4). It supports nail health by playing a role in collagen formation.

Iron deficiency results in spoon nails, which occur when the nails arch inwards and become brittle (5). To maintain nail health, at least 8 mg/day of iron is recommended for daily intake (6). Foods like lean meat and seafood, nuts, beans, and fortified food have high amounts of iron which you can add to your diet.

*Iron should only be taken if prescribed by your doctor.


Cranberries contain silicic acid which supports nail health. A study showed that continuous intake improved brittle nails and strengthened them (7). Another study saw that silicic acid also helps in the maintenance of the nail's connective to keep it healthy (8).

Vitamin C which is also present in cranberries enables nail health by supporting collagen formation which is essential for nail formation to keep it strong (9). Vitamin C deficiency also shows signs of nail brittleness (10).

Vitamin plan


Collagen is one of the key components of nails. Patients who have taken collagen supplements have seen increased nail growth, fewer broken nails, and improved brittle nail conditions (12). Meats with connective tissue in them like brisket and chuck steak are rich in collagen, as well as bone broth (13). It can be sourced from supplements or increased intake of collagen production boosting food like meat, dairy, nuts, and seeds (13).


Lastly, biotin or vitamin B7 is one of the recommended nutrients for brittle nails (14). Multiple studies have proven that patients improved their brittle nails through the use of biotin supplements (15, 16). Aside from its help with nail health, it’s present in fatty acid, glucose, and amino acid metabolism and cell signaling and its deficiency can cause nail brittleness (17). Foods like animal organs, eggs, seeds, and nuts are good sources of biotin and 30 micrograms/day of it is recommended (18).

Put together your own vitamin plan

The next step to maintain and support your nail health is to find the best way to get the vitamins that you need. It is always best to get the vitamins that you need from your diet, but in cases where you can’t get all the nutrients you need from diet, supplements can help support your intake.

Eating healthy and choosing the right supplements for your vitamin plan can help you improve your nail health.
