What is the best vitamin for hair growth? The FNB at the IOM of the National Academies recommends the following daily intake of iron in adults:. Food sources of iron include lean meat, seafood, and fortified cereals and grains.

Omega-3 fatty acid deficiency is associated with hair and eyebrow loss. One randomized controlled trial among women with hair loss found a supplement containing mg of fish oil a source of omega-3 fatty acids reduced hair loss and improved hair thickness. But the supplement also contained antioxidants , which fish oil is weak in, and the added antioxidants may have contributed to the beneficial results.

There is no set recommended dietary level for omega-3 fatty acids. However, it is encouraged for adults to consume the following amounts of omega-3 fatty acids daily to ensure nutritional adequacy:. Foods rich in omega-3 fatty acids include the following:. A healthy diet with enough nutrients and protein provides the best support for hair growth.

Sometimes, a nutrient deficiency may contribute to hair loss. If you have low levels of zinc or iron, taking a supplement may help restore nutrient levels and promote hair growth.

But if your levels of these minerals are already within normal range, then a supplement likely will not support hair growth or prevent hair loss. Taking zinc when not needed can do more harm than good, contributing to unwanted side effects and affecting the absorption of other minerals essential for health.

It depends. Supplements correcting a nutrient deficiency may reduce hair loss. However, the data do not support supplements targeted for hair growth in individuals already getting enough of these nutrients. There is no best supplement for hair growth.

Instead, overall nutrition from a balanced diet is fundamental for hair growth. Contact your healthcare provider to discuss whether hair loss may result from an underlying issue or nutrient deficiency. Despite its mainstream popularity, there is limited evidence to support the use of biotin for hair regrowth.

In healthy individuals, biotin does not promote hair growth. However, biotin supplements may encourage hair growth among people with low biotin levels. Almohanna HM, Ahmed AA, Tsatalis JP, et al. The role of vitamins and minerals in hair loss: A review. Dermatol Ther Heidelb.

Zinc shares a similar story with iron in that it can become dangerously toxic if taken unnecessarily. That said, there may be an association between supplementation and hair growth for those with a zinc deficiency.

Generally, research shows that a deficiency in a micronutrient could be a controllable risk factor by supplementing correctly in alopecia development, prevention, and treatment.

Rosen and Draayer agree with the science. For other sources of hair loss, Draayer says micronutrients "are likely not going to have a significant impact on hair loss.

In all cases, it's important to address the underlying cause. We require different amounts of micronutrients, and when it comes to the four we need for hair health, here is what we need and how to get it from food:.

Adults need at least 30 mcg per day, which can be met by regularly consuming foods like eggs, salmon, mushrooms, sweet potatoes, avocados, beef or chicken liver, and sunflower seeds. People between 19 and 70 need 15 mcg or IU daily. The best way to get your vitamin D is to be in the sun with skin exposed on a consistent basis.

Eating vitamin D-rich foods often, like fatty fish salmon, trout, tuna, and mackerel , eggs, and fortified dairy products and cereals, can help you meet your needs. Plus, including fat in your meals and snacks regularly will support your vitamin D status, since it is fat-soluble meaning it requires fat for absorption.

Men need 8 mg while women need 18 mg per day. You can meet your needs by eating heme animal sources like red meat and poultry and non-heme sources plant-based sources like legumes and spinach regularly, however, heme sources are the most bioavailable. Boost your non-heme iron absorption by eating foods rich in vitamin C, like oranges, broccoli, and bell peppers.

Men need 11 mg and women need 8 mg daily. Meet your zinc requirements by including meat, fish, seafood, dairy products, and eggs in your diet. While beans, nuts, and whole grains offer zinc, it is less bioavailable than its animal sources.

Draayer points out that "in some cases, individuals may require supplementation due to deficiencies, medically necessary dietary restrictions, or specific health conditions. However, it is important to consult with a healthcare professional before adding supplements to your routine, as unnecessary supplementation or large doses of vitamins may not provide additional benefits and could potentially lead to adverse effects.

Outside of vitamins and minerals, there are several other natural remedies to consider and what you choose depends on the underlying issue, according to Rosen, who stresses always finding the culprit first.

For example, hypothyroidism and hormonal imbalances can be addressed with nutrition, supplement, and lifestyle interventions, she says. And when stress is the issue, Draayer recommends practicing stress-reduction techniques, such as yoga, meditation, or deep breathing exercises.

Other remedies include scalp massage, essential oils and other oils such as pumpkinseed oil , medicinal plants , proper hair care, and platelet-rich plasma PRP.

Just like when you consider supplementation, consult with your healthcare provider before trying other options. Hair loss can happen naturally during life transitions that impact hormones like pregnancy or because of major stressors like a car accident or a divorce, which will typically be resolved once the situation does.
