Frequently Asked Questions
Can the Isotonix Daily Essentials Kit products be taken at the same time?
Yes. The Isotonix Daily Essentials Kit products can safely be taken at the same time, provided that one follows the recommended serving size for each product.
Why are Isotonix supplements better than standard supplements?
Isotonix formulas are more effective than standard supplement formulas because they offer the best way to get the maximum delivery of vitamins and minerals into the bloodstream. Isotonix formulas are also the fastest and most effective way to receive vitamins, minerals and nutrients. The stomach has very little work to do because the pH and tonicity are carefully designed to allow the stomach to quickly release all the nutrients into the small intestine. With the Isotonix formulas, this process takes about five minutes, whereas a standard vitamin tablet can take up to four hours.
What sets Isotonix OPC-3 apart from other bioflavonoid products?
Isotonix OPC-3 offers scientifically supported oligomeric proanthocyanidins, or OPCs, found to be the most powerful antioxidants for human health. In addition to being powerful antioxidants, these individual OPCs have been shown to provide a myriad of specific health benefits. This science-driven selection of OPCs is unique to OPC-3, as is the Isotonix delivery system, which enables rapid and highly efficient absorption of the OPCs. The potent nutrients, in combination with the highly effective delivery system, makes OPC-3 the most powerful free radical scavenging product available.*
Why do I need to take a multivitamin?
A good quality vitamin and mineral supplement creates a sound micronutrient foundation to accompany a balanced diet. Vitamins and minerals help to support a healthy immune system, promote the conversion of food into energy, support a healthy cardiovascular system, support strong bones, promote mental clarity, maintain normal metabolic functioning, promote healthy growth and repair of tissues, help maintain normal blood pressure and help maintain water and electrolyte balance in the body.
What does “Activated” refer to in Isotonix Activated B-Complex?
"Activated" refers to the active forms of vitamins B6 and B12 and folate. Using forms other than these activated forms requires that the vitamins be enzymatically activated prior to utilization by the body. Not only does this take time and energy within the body, there are circumstances in which this reaction is either slowed or inhibited.
Why should I take calcium?
According to the Surgeon General, taking a calcium supplement daily is key to preventing and treating calcium deficiency and to helping reduce the risk of osteoporosis.** Currently, osteoporosis affects over one-third of postmenopausal women in this country. Recent clinical statistics also indicate that aging men are also likely to become susceptible to osteoporosis.* Everyone needs calcium. Practically no one ingests enough calcium in their daily diet. Besides being helpful in supporting and maintaining bone integrity, calcium serves a dynamic role as a mineral. It's very important in supporting the activity of many bodily enzymes and maintaining proper fluid balance. Isotonix Calcium Plus also promotes the normal contraction of muscle.
**Adequate calcium and vitamin D, as part of a well-balanced diet, along with physical activity, may reduce the risk of osteoporosis.
I am healthy, so why should I take Isotonix OPC-3?
Everyone is vulnerable to the aging process caused by continuous free radical damage. Athletes tend to be exposed to elevated levels of oxidative stress. Free radicals develop as byproducts during metabolism when calories are processed with oxygen. Athletes inhale 10 to 20 times more oxygen during physical activity over rest periods. The increase in activity creates additional free radicals. These free radicals are known to limit performance, as free radicals appear to take their toll on muscle tissue. Studies on recreational athletes have shown a 20% endurance increase with OPCs, as compared to a control group receiving a placebo. Another study has shown that athletes using OPCs suffered significantly less muscle cramping during and after performing. Isotonix OPC-3 helps to maintain healthy blood flow and this supports oxygen supply to muscles.*

I've been using this product for many many years and love it. I truly believe it helps in maintaining steady levels in my blood work results. I was disappointed the last time I placed an order when, for the first time ever, they were out of the product and it took nearly a month to be filled. It was a terrible inconvenience and I certainly hope it doesn't happen again.

Dear Valued Customer,
Thank you for taking the time to share your thoughts on the nutraMetrix Isotonix® Daily Essentials Kit - With Iron! We are so happy to hear you are pleased with the products! We can certainly understand how you feel and nutraMetrix was able to put off this price increase for almost five years. The decision to implement a minimal price increase was not taken lightly, but the change will help us navigate rising costs in our production and supply chain so we can continue to deliver the highest quality of performing products with the very best ingredients and formulations.
Thank you again!
