Healthier hair won’t happen on its own

Featuring powerful nutraceuticals and nutrients that can promote stronger, thicker hair.


Keratin is one of the main proteins that makes up hair. This amino acid is one of the building blocks that allows your body to produce this protein and create strong, healthy hair.1

Saw palmetto

When certain androgens, like DHT, build up in the body, they can cause hair follicles to shrink and hair to get thinner. This natural DHT-blocker can help reduce the elevated levels of this hormone that are harmful to hair.2, 3

B-complex vitamins

Niacin, riboflavin, biotin, folate, and vitamin B12 deficiencies have all been associated with hair loss.4, 5 Resolving a nutrient deficiency is often the first step in making sure healthy hair can grow.

Horsetail extract

Horsetail is rich in silica, a mineral that’s important for nails, skin, and hair. Silica helps deliver essential nutrients to your hair follicles and strengthens hair from the inside out.2

Got questions? We have answers.

What vitamins am I lacking if my hair is thinning?

An unhealthy diet or even just being a picky eater can lead to a deficiency in a particular nutrient. This, in turn, can cause hair thinning, textural hair changes, and even hair loss.

In people with androgenic alopecia, hair thinning is caused by a mixture of factors. A nutrient deficiency is often (but not always) one of the factors.

If your hair is thinning, there’s a good chance that you could be deficient in a mineral like zinc, that helps your body create hair proteins, or a B-complex vitamin that helps regulate hair thickness. But your deficiency could also be in something much more specific, like the amino acid cysteine, or something else altogether.

People often don’t realize that vitamins and minerals work together. When a nutrient deficiency occurs, the functions of other vitamins and minerals can be affected too. Regardless of what vitamin or mineral you’re deficient in, a blend of essential nutrients is crucial for healthy hair.

What vitamins and minerals are in Nutrients?

We formulated Nutrients so that each capsule was filled with vitamins and minerals that can help boost hair growth. In each capsule, you’ll find essential nutrients like calcium, zinc, B-complex vitamins, vitamin C, and vitamin E. Additionally, you’ll be taking two amino acids, L-Cysteine and L-Taurine, that your body needs to create hair.

What nutraceuticals are in Nutrients?

In addition to vitamins, minerals, and amino acids, we decided to include extracts from two plants: saw palmetto and horsetail. Horsetail extract actually contains essential minerals like selenium and silica, as well as the amino acid cysteine. Saw palmetto is a natural DHT blocker that is rich in phytosterols, which are plant-based compounds that are good for your heart.

What is DHT and why do we need to block it?

DHT, also known as dihydrotestosterone, is an androgen that builds up in the body of people who have androgenic alopecia. When it reaches high enough levels, DHT starts to affect hair follicles, preventing hair from growing. When DHT is blocked and levels drop back down, your hair follicles can start producing hair again.

Can I take more than one dose of Nutrients a day?

If you accidentally took a double dose of Nutrients today, don’t worry — it’s not a big deal.

That being said, Nutrients* were specially formulated so that you just need one dose a day. You won’t get any benefits from taking more than a single capsule per day. And in the long run, taking multiple doses per day could do you more harm than good.

*Check with your doctor or dietitian before taking both Nutrients and another multivitamin.

Hair vitamins: The nutrients you need for healthy hair

In an ideal world, everyone would be able to get all of their essential nutrients from the foods they eat. If you like eating fruits and vegetables each day, understand the benefits of healthy fats, and can differentiate between incomplete and complete sources of proteins, there’s a good chance that you’re getting all the vitamins and minerals you need to stay healthy. 

Unfortunately, many people don’t consume a balanced diet like they should. It’s no surprise: As we get older, our lifestyles get busier. Whether it’s because you’re trying out a new diet, attempting to lose weight after lockdown, or are just too busy to cook food from scratch, you might not be getting all the nutrients your body needs.


Important facts about vitamins

If you don’t eat a healthy, varied diet, you can end up with a vitamin deficiency. Deficiencies can also occur due to illnesses, gut absorption problems, or frequent alcohol consumption. Essentially, your body won’t be getting enough nutrients to function the way it should. 

You may not notice a deficiency at first. But if allowed to progress, your body will have to prioritize certain functions over others it considers to be less important. 

Vitamin deficiencies and hair

You’re probably aware that nutrients are important for your organs and bodily functions, but they also help prevent hair loss and keep hair healthy. For example, certain nutrients are specifically involved in the production of keratin, the main protein found in hair and skin.6

Vitamins and minerals also help promote good blood circulation, nutrient absorption into hair follicles, and skin and hair cell regeneration, which are all necessary for healthy hair growth.

While nutrient deficiencies can cause an array of different health issues, certain deficiencies are particularly likely to cause hair problems. Hair can become brittle, thinner, or stop growing altogether.

Although some people can resolve their hair problems by eating more of certain foods, others need extra amounts of specific vitamins or minerals. Taking a supplement can help restore hair growth in people experiencing deficiencies.

Supplements aren’t for everyone, though, and too much of a good thing isn’t always healthy. If you already consume a nutrient-rich diet or are already taking a multivitamin, taking an additional supplement for hair growth could be excessive and unnecessary.

The importance of B-complex vitamins

There are eight different vitamins in the B-complex family. These vitamins work together to perform a variety of important functions in your body.

B-complex vitamins help break down the macronutrients you consume, allowing protein, carbohydrates and fat to be processed efficiently. These B-vitamins also perform a variety of other roles, like helping transport oxygen and nutrients around your body and supporting the function of your brain and nervous system.7

B-complex vitamins are important for healthy skin and hair. Deficiencies in several of these B-complex vitamins (niacin, riboflavin, biotin, folate, and vitamin B12) have been associated with hair loss.4, 5

Niacin (Vitamin B3)

Niacin, also known as nicotinic acid, nicotinamide or vitamin B3, is part of a group of organic compounds that kickstart the energy reserves. Niacin can help promote keratin production, making it important for both hair and skin cells.6

Vitamin B3 is naturally found in many foods. Foods with high quantities of niacin include beef, poultry, salmon, rice, tomato sauce, and peanuts.8

Pantothenic acid (Vitamin B5)

Vitamin B5 is also known as pantothenic acid. Like other B-complex vitamins, this nutrient helps break down food into energy. You can find vitamin B5 in a wide variety of foods, including eggs, dairy, mushrooms, cauliflower, legumes, and leafy green vegetables.

While vitamin B5 on its own doesn’t directly promote hair growth, this nutrient can influence hair growth and diameter. It is also able to help reduce inflammation, prevent early hair graying, and maintain good hair follicle and scalp health.9, 10

Vitamin B6 (Pyridoxine)

Vitamin B6 helps support your body’s immune system function and metabolism. It’s vital as it helps make hemoglobin, a protein that transfers oxygen to your cells.11 Without enough hemoglobin, your cells won’t get enough air. Supplementation of this nutrient is also thought to help improve conditions for hair growth and reduce the amount of hair loss.12

If you’re not getting enough vitamin B6, you might be feeling tired all the time, weak or lethargic. You may also become anemic, or experience skin and oral health problems. Foods like beef, tuna, poultry, potatoes, chickpeas, and bananas can help you increase your vitamin B6 intake.

Biotin (Vitamin B7)

Biotin, also known as vitamin B7 or vitamin H, is the only B-complex vitamin that your body is able to produce. You can also get your recommended daily amount of biotin from the foods you eat, especially protein-rich plants or meat products. 

Biotin is another vitamin that has been associated with hair loss. Biotin deficiency is rare but can lead to skin problems, hair loss symptoms, and brittle nails.5

Insufficient biotin can be a genetic issue or due to illness, but it might also be due to your diet. Do you like blending raw eggs into smoothies or protein shakes? That trend can actually cause biotin deficiency.

If you suspect your biotin deficiency is due to your love of eggs, don’t worry — it’s only raw eggs that cause this problem. Cooked eggs are actually great sources of biotin.

Vitamins C and E: Antioxidant nutrients

Vitamin C and vitamin E are essential nutrients, but they’re also antioxidants. Antioxidants help prevent the damage associated with free radicals, which cause oxidative stress. 

Free radicals are compounds that are created when you convert food into essential energy. They can also be taken in by your body through air pollution or cigarette smoke, or other environmental hazards.13

Free radicals can cause damage to your cells and are associated with various health problems. The resulting oxidative stress has been associated with different types of hair loss.4

Vitamin C

Beyond protecting your body from free radicals, vitamin C helps your body absorb iron, an essential mineral that helps carry oxygen around the body through your blood.5

It’s important to make sure you’re getting enough vitamin C as too little can lead to scurvy and in turn, symptoms of hair loss.

Vitamin E

Vitamin E is also more than just an antioxidant. This vitamin helps maintain the health and function of your immune system, blood vessels and metabolism.14 Vitamin E might also be able to reduce oxidative stress in the scalp, which in turn benefits both skin and hair.15

Zinc: An essential mineral for cellular metabolism

Zinc is an essential nutrient that has a myriad of different functions in the body. It helps your body synthesize DNA, defend itself from viruses and bacteria, create new cells, and heal wounds. It’s also crucial for the production of proteins, like keratin.16

Zinc deficiency can lead to skin problems and hair loss, and notably, it’s specifically been associated with androgenic alopecia. When people with this type of hair loss have taken part in nutrient deficiency research studies, around 10 percent of them have had a zinc deficiency. 5, 17

Most people get enough zinc from the foods they eat. However, people following a plant-based diet are at particular risk of zinc deficiencies. This is because certain healthy foods — specifically legumes and whole grains — contain compounds that bind to zinc and prevent it from being absorbed. 

If you’re a vegetarian trying to increase your zinc levels, you may want to consider consuming sprouted grains or legumes, like bean sprouts. The sprouting process reduces the levels of those compounds and allows your body to take up zinc much more easily. 

Nutraceuticals that benefit hair 

Sometimes, you don’t need to take vitamins and minerals in their raw form to still get them and their benefits. Some plant extracts, for instance, are good sources of several different nutrients. Others have compounds that can support your health in different ways. 

Horsetail extract

Horsetail extract is a unique plant that’s rich in hair’s building blocks. It contains an amino acid called cysteine and a mineral known as silica. Both of these are important for keratin production and therefore essential for hair growth. Horsetail also contains selenium, is able to increase calcium absorption, and boosts blood flow to the scalp.2

Saw palmetto

Saw palmetto is a plant that’s best known for its ability to block an androgen called DHT (dihydrotestosterone).3 DHT levels tend to build up in people with androgenic alopecia. When DHT levels increase, hair follicles are affected and eventually stop producing hair. However, if the amount of this androgen drops back down, hair follicles can start producing hair again. 

Saw palmetto is also rich in cholesterol-reducing phytosterols, which means it may have even more benefits beyond supporting hair health.18 Phytosterols are generally thought to be good for your heart.
