Proven to Improve Sleep & Reduce Anxiety, Stress
Optimal Balance® is the product of decades of independent university research on micronutrient therapy. Separately formulated for men and women (and safe for children), this powerful formula contains every single nutrient scientists have found to be essential for human health.
Optimal Balance® replaces your daily multivitamin because it contains all the essential vitamins and minerals in a highly bioavailable format. This means your body will actually be able to absorb and put each nutrient to use.
The combination of microground absorbable vitamins, chelated minerals, potent antioxidants, and carefully chosen botanicals work together to deliver the key ingredients your body needs each day. Optimal Balance® targets the underlying causes of stress, anxiety, and insomnia by crossing the blood-brain barrier to alleviate symptoms at the source.*
University researchers found that Optimal Balance® significantly improved sleep problems, anxiety and stress when taken at a dose of 3 capsules twice per day.
Researchers commented that “Treatment completers reported reliable and clinically significant change in insomnia severity…stress…and on at least two aspects of sleep measured by the CDS-M.”

Why Optimal Balance?

Our Story
Hardy Nutritionals® founder David Hardy is the world’s recognized pioneer in micronutrient supplementation. His formulations† have been the subject of multiple independent university studies including double blind studies for mood and mental health including sleep, stress, anxiety, depression, ADHD, autism, bipolar disorder and PTSD. Hardy Nutritionals® micronutrient formulations are 100% drug free, and are powered by our proprietary NutraTek™ mineral delivery technology, which combines each mineral with specialized organic molecules—just like in nature—to optimize absorption and distribution to body cells.*
Our Products
Hardy Nutritionals® provides two levels of micronutrient supplementation. Our general health formulation, Optimal Balance® provides powerful nutrition for healthy children and adults and those suffering from light to moderate stress or insomnia. Our clinical strength formulation, Daily Essential Nutrients is designed for children and adults with acute symptoms who need a more concentrated formula, for addressing the symptoms of severe anxiety, depression, ADHD, autism, bipolar disorder and PTSD. Hardy Nutritionals® products provide ongoing relief to many thousands of people each month.

Your Solution

The powerful balance of ingredients in Optimal Balance® work together to address nutrient deficiencies which affect multiple pathways within the body that are associated with stress and sleep.*
Unlike average multivitamins, the nutrients in Optimal Balance® have been shown to cross the blood-brain barrier so they can be put to use by the body’s cells, allowing the body to make and regulate its own cofactors such as melatonin & 5HTP rather than synthetically receiving them.
Most people report improvement in stress, mood and sleep symptoms within 30 days, with increased benefits from continued use. Optimal Balance® should be taken twice a day for best results.*


All the essential vitamins are found in both Men’s and Women’s Optimal Balance®. Even with a healthy diet, science has shown that most people are vitamin deficient, which is related to a long list of health problems.
All the essential minerals are provided in both Men’s and Women’s Optimal Balance®. The minerals are finely ground, chelated, and highly concentrated for maximum absorption using our proprietary NutraTek™ chelation complex.
Plus: Our added blend of botanicals and antioxidants provides protective effects against cardiovascular disease, cancer, inflammation, and even neurodegenerative diseases.*

What are the most important things I need to know to have success with taking Optimal Balance®?

Understanding these important factors will make all the difference in your success using Hardy micronutrients: The brain and body need optimal nutrition to function correctly. Consistent and regular intake of Optimal Balance® ensures that your nutritional foundation is solid.   Gut health is critically important. Without adequate gut health, you won’t properly absorb the nutrients you need. Take our Gut Health quiz to learn more.

How soon should I expect to see results?

Some individuals see dramatic results within a few days; however, Optimal Balance® typically produces results gradually over a period of several weeks or months (and sometimes longer for certain conditions). Medical journal publications have reported impressive results in people who took our products at recommended levels for at least 8 weeks. But it’s safe to say that no one will see the full benefits of Optimal Balance® in just 8 weeks— many people continue to report subtle improvements for years after.

How much do I need to take?

The recommended dose of Optimal Balance®—3 capsules, 2 times per day, with meals—is based on extensive experience addressing various symptoms in thousands of people, including adults, adolescents, and children. Independent university research has shown that people respond best, particularly in the first few months, by consistently taking the recommended dose.

How much do children need to take?

In general, we recommend the following initial dosages of Optimal Balance® for children diagnosed with psychiatric conditions, based on published research and clinical experience:

  • 2-3 years: Work up to 2 capsules/day (with food).
  • 4-5 years: Work up to 4 capsules/day (with food).
  • 6 years or older: Work up to 6 capsules/day (with food).

Is this a vegan friendly product?

Yes. Optimal Balance® is encapsulated in veggie caps and contains no animal by-products.

Is Optimal Balance® top 8 allergen free?

Yes. Optimal Balance® is wheat, peanut, egg, dairy, fish, nut, soy and shellfish free.

Is Optimal Balance® non-GMO?

Yes. Optimal Balance® is free from GMOs.

How do I get started?

The simplest way is to take 1 capsule 2 times per day the first day, two capsules 2 times per day the second day, and by the third day, you’ll be taking the full recommended dose of 3 capsules twice per day. Most people have no problem tolerating Optimal Balance® when they gradually introduce it in this way. Those who may be sensitive can choose to increase the dose more gradually (for example, increasing their dose by one capsule per day so it takes 6 days to reach the recommended dose of 6 capsules per day).

Can I stop taking Optimal Balance® once I’ve seen a positive response?

Supplying your body with nutrients on a regular daily basis will ensure your body gets the critical and essential ingredients it needs for maximum wellness and optimal results. Consistently eating nutrient-rich food is also very important, but even if you’re carefully choosing your diet, it’s still very difficult to get all the nutrition you need from food alone. This is especially true for anyone with stress or sleep issues, because according to research, these people often have higher-than-average nutrient needs.

Over the years, researchers have documented many cases where people with mood, anxiety, or behavioral issues responded favorably to our nutrient therapies and then stopped taking it, thinking they didn’t need it anymore. The unfavorable symptoms returned. Restoring the nutrients improved their symptoms dramatically again. Most people who experience this contrast decide that it’s worth taking Optimal Balance® regularly to enjoy the stability it provides.

Does Optimal Balance® have any side effects at our recommended levels?

Occasionally, when people begin taking Optimal Balance®, they may have looser stools than usual for a few days, but as the body adjusts to the additional nutrients, this typically normalizes, as it does when you introduce a new food to your diet. It is also normal for a person’s urine to be brighter yellow in color while they are taking Optimal Balance®. This is a harmless side effect of taking vitamin B2 (also called riboflavin). It’s very rare for people to have any other side effects.

Do I need to add extra vitamins or minerals to Optimal Balance®?

It’s rare that people need to take additional vitamins or minerals, because Optimal Balance® is designed to meet nearly everyone’s daily needs at the suggested serving. This all-in-one approach gives you clear advantages in terms of convenience and cost-savings. However, some people have a specific need for additional nutrients. For those people, our clinical strength micronutrient formula, Daily Essential Nutrients, may be a better fit.
