Why Older Adults Should Consider a Multivitamin

30 trillion

Vitamins and minerals support over 30 trillion cells in the human body, fueling processes of energy production to maintain the health of tissues and cells.

Zero

The body makes zero essential vitamins or minerals on its own; you must get them from your diet or supplements to support a healthy metabolism.

<10%

Fewer than 10% of Americans meet adequate intake recommendations for key nutrients through diet alone.

Support Aging With B Vitamins

B vitamins are essential for many bodily functions, but absorption declines with age — especially for vitamin B12, which supports energy and the nervous system. Isotonix® Multivitamin Fifty Plus provides all eight essential B vitamins, including highly bioavailable and active forms of B6, B9 and B12, helping you meet your daily needs in one easy serving.

Frequently Asked Questions

  • A vitamin is an essential nutrient needed for normal metabolism that the body cannot produce and must obtain from external sources. Vitamins help convert food into energy and support growth and tissue repair. Long-term low vitamin levels can cause deficiencies, which are easily prevented by proper vitamin intake.

  • Unlike other multivitamin supplements, Isotonix Multivitamin Fifty Plus uses the Isotonix delivery system for efficient nutrient absorption and maximum benefit. This means less nutritional value is lost, ensuring that you get the maximum benefit from this multivitamin. It’s specially formulated for older adults, whose bodies absorb nutrients less efficiently with age, ensuring they get key vitamins and minerals like folate, vitamin C, zinc and vitamin B12.

  • The vitamin E in Isotonix Multivitamin Fifty Plus is the natural, high-activity D-alpha tocopherol. It is in the active form to aid water solubility. This form of vitamin E is superior in terms of absorption and retention in the body. The natural form of alpha-tocopherol is known as D-alpha tocopherol, whereas the synthetic form is called DL-alpha tocopherol.

Very hard too measure

Very hard to measure the powder its so fine that its spills over the cap, not sure if I'm using too little or too much. This is my first time using the over 50 brand, what's changed with the texture? Not sure if I will buy this again.

Response from Customer Service:

Thank you so much for your feedback and for sharing your experience with Isotonix® Multivitamin Fifty Plus. We appreciate you letting us know about the challenges with measuring the finer powder, and we will be sure to inform our product managers of your comments. One tip that may help with pour control is to poke a small hole in the center of the foil seal, which can make it easier to dispense the powder more accurately. Your feedback is important as we strive to improve our products. Thank you for being a valued member of our community!

Love this vitamin supplement

I am a 62 years young. With this product it me more vitamins and minerals which they knew we would need, at are age. This is one supplement I don't miss taking daily. I wish it came in a 90 serving instead of just a 45 serving. So I change it in my morning Daily Essential routine

Difficult to Use

The bottle for the vitamin powder is impossible not to spill when trying to measure out two capfuls as recommended.

Response from Customer Service:

Thank you very much for your feedback on nutraMetrix Isotonix® Multivitamin Fifty Plus. We apologize for the difficulty you’ve experienced with pouring the powder, and we appreciate you bringing this to our attention. Your comments will certainly be shared with our appropriate teams to help us improve. For better pour control, we recommend poking a hole in the inner foil seal rather than removing it completely—this can make measuring easier and help reduce spills. Thank you again for your input and for being a valued customer!
