The Isotonix Difference
Experience what a multivitamin should really feel like. Most multivitamins are trapped in tablets or capsules, forcing your body to do all the work to break them down, absorb and utilize their nutrients. But nutritional value means nothing without absorption. Isotonix Multivitamin delivers a carefully balanced blend of essential vitamins and minerals in an isotonic solution — the form your body prefers. This means rapid and controlled nutrient delivery. No need to digest a capsule or tablet. Get fast-acting, bioavailable support right when your body needs it.

Frequently Asked Questions
Why is taking a vitamin supplement important?
Even with a balanced diet, many people fall short of getting the essential vitamins and minerals their bodies need daily. Modern farming practices, busy lifestyles, food processing and dietary restrictions can all limit the variety and nutrient density of the foods we eat. Vitamin supplements help bridge these gaps, ensuring your body has the critical nutrients required to support energy production, the immune system, bone health, mental clarity and overall vitality. By giving your body consistent access to essential nutrients, you help support overall wellness that can impact long-term health, empowering you to live better, every day.
Are methylated multivitamins Important?
Yes, for many people methylated multivitamins are important. "Methylated" means certain vitamins—such as B12 (methylcobalamin) and folate (5-MTHF) — are provided in their active, bioavailable forms. This is crucial because up to 40% of the population has a genetic variation (such as MTHFR mutations) that makes it harder to properly process and activate standard forms of B vitamins. Methylated vitamins bypass this issue, supporting energy production, mental clarity, cardiovascular health and detoxification more efficiently. Choosing a multivitamin with methylated nutrients helps ensure that your body can use these vitamins immediately, without unnecessary steps that could slow absorption or effectiveness.
If I already take a quality multivitamin, do I still need additional magnesium, B vitamins or vitamin D3?
While a high-quality multivitamin provides a strong nutritional foundation, certain nutrients — like magnesium, B vitamins and vitamin D3 — are often needed in higher amounts than what multivitamins typically provide. For example, magnesium plays a role in over 600 enzymatic reactions, yet many people fall short due to poor dietary intake. B vitamins, especially in times of stress or high energy demand, may be needed through additional supplementation to support adequate levels beyond a standard multivitamin serving. Vitamin D3 is another key nutrient where higher, individualized supplementation is often recommended, especially for those with limited sun exposure or other lifestyle factors that may demand additional vitamin D3. In short: A multivitamin covers your base needs, but depending on your health goals, lifestyle and lab results, targeted supplementation can provide optimal support.

Excited about my multivitamin
5 out of 5 star rating.
From the time I was a child, I remember my mom starting my day with a multi. I don't remember much else, not even feeling any different. When I was introduced to Isotonix Multivitamin (over 28 years ago), I drank for the nutrients. I didn't really expect to feel the power of an excellent multivitamin that my system actually absorbed. What a difference quality and absorption make. I will never miss a day of the product. Thank you.
