Worried about brittle and broken nails? To make them grow strong and healthy, you first need to rule out nutritional deficiencies and other issues like fungus, which can make your nails brittle and discolored.

Once you do so, biotin, omega-3, and collagen supplements can do wonders for your nails. A good multivitamin supplement will ensure you get all the vitamins and minerals you need for your nail health. However, you need to ensure your body is absorbing these nutrients well and making full use of them.

Here are 5 nail growth supplements that will strengthen and thicken your nails, making them shine with health.

5 Best Supplements for Strong and Healthy Nails

1. Best for Nail Growth

Also known as vitamin H, biotin (vitamin B7) is a water-soluble vitamin that offers numerous health benefits. The name biotin originates from 'biotos,' a Greek word meaning 'life.'

Biotin plays a vital role in the conversion of food to energy for various body functions. Apart from protecting against certain cognitive disorders, maintaining nervous system health, and having anti-inflammatory benefits, biotin is essential for keeping your nails, skin, and hair healthy.

Biotin deficiency results in hair loss as well as nail and skin problems. As supplementing with biotin strengthens brittle nails, Approved Science's Biotin MD™ brings a dose of 10,000 mcg of pure biotin per tablet to promote nail growth. Clinical studies have found this to be the optimal potency for the effective supplementation of biotin. In addition, this supplement is 100% vegan-friendly.

Omega-3 fatty acids offer numerous benefits for the mind and body. Aside from boosting brain development and cognitive functioning, treating depression and improving your mood, and reducing the risk of heart disease, Omega-3 fatty acids are great for nail strength too.

As Omega-3 reduces inflammation and enhances the health of your nail beds, it can help your nails grow thick and strong in no time. With these benefits in mind, Approved Science’s Omega-3 MD™ offers you 900mgs of EPA and 600mgs of DHA. This is a 100% pure omega-3 supplement with pharmaceutical-grade deep ocean Omega-3 for the best results.

4. Best for Nail Moisture

Collagen is the most abundant protein in our system that provides structures and support throughout the body, including our nails. However, our collagen stores diminish as we age, so using collagen supplements can replenish the collagen in our system to help our joints, skin, hair, nails, and more.

Apart from strengthening hair follicles and slowing down graying, collagen is also vital for joint health, as it supports cartilage growth. Collagen supplements made from hydrolyzed marine collagen are absorbed faster than other collagen types, which makes them the best choice.

In line with this, Approved Science's Collagen Pills contain vitamin C to boost collagen production and BioPerine® to increase the absorption and bioavailability of nutrients. This results in all-around better hydration of your body, providing more moisture to your nails to prevent brittleness.

5. Best for Nail Health

Approved Science's BioPerine® is a thermogenic bioavailability enhancer, meaning it increases the bioavailability of nutrients in the food or supplements taken along with it. As it contains 95% piperine, a black pepper extract that triggers heat production in the small intestine to boost the absorption of nutrients, this supplement can increase the absorption of beneficial nutrients by up to 2000%.

Along with being beneficial for blood and brain health and having antioxidant and anti-inflammatory benefits, this supplement optimizes your overall health, which in turn results in healthier nails.
