High carotenoid concentrations have been shown to lower the severity of arthritis, improve heart and brain health, and reduce inflammation systemically and locally in tissues such as the retina. But how can doctors measure a patient’s carotenoid level so they can accurately gauge someone’s general nutritional health?

Enter LifeMeter. This innovative medical device is a simple, precise and non-invasive test that consistently and objectively measures carotenoid levels in your patients in less than three minutes using a customized spectrophotometer. Knowing a patient’s LifeMeter level facilitates the “nutrition discussion” and helps them make positive nutritional changes.

This exciting technology has matured out of the laboratory and is ready for clinical implementation. Below are several ways your practice (and patients) can benefit from LifeMeter.

Accurate and Reliable

Similar devices measure carotenoid levels from different locations on a patient’s palm, leading to a different outcome every time. LifeMeter utilizes reflection spectroscopy to measure the concentration of carotenoids in one area: the fingertip. The result is a concentration, not a carotenoid total. This means you’ll get an accurate and repeatable result regardless of fingertip size. The LifeMeter level correlates significantly with macular pigment level, circulating carotenoids, and the concentration of these vital nutrients in other bodily tissues, such as the heart and brain.

Encourages Compliance

It’s one thing to tell a patient to take a medication or supplement, but you can never really know if they’ll comply. With LifeMeter, once you’ve initiated a carotenoid supplement regimen, any improvement in carotenoid status can be seen within a month. And if their score stays the same or goes down, it means the patient hasn’t been compliant with their new regimen. By using LifeMeter, you’ll have quick and accurate feedback on any nutritional status changes. When patients see their LifeMeter level go up, they’ll get excited and know they’re on the right track.

Preventative Measure

LifeMeter promotes a proactive – not reactive – approach to health. Those with a low carotenoid concentration report having trouble driving at night and struggle with vision in glare, and tend to have poor contrast sensitivity, less protection against infection and disease, reduced speed of visual and cognitive processing, increased chance of sunburn, and higher frequency of eye strain and fatigue.


Studies show that adding and monitoring vital carotenoids in the body enhances visual and cognitive performance and overall health. Additionally, these nutrients are proven to aid in managing symptoms of age-related macular degeneration (AMD), a leading cause of vision loss for older adults.

Measure the Carotenoid Levels of All Patients

LifeMeter isn’t for one segment of your patients. It’s for everyone! There are over 30 peer-reviewed publications demonstrating its validity and effectiveness in over 2,000 subjects of varying races, ethnicities, and ages.

No Commitment

Unlike similar equipment, there are no sales goals to meet when purchasing or financing a LifeMeter. The device is yours, and to use it how you see fit.


With continued use, you and your patients will see the value of measuring carotenoid levels with LifeMeter. For more information on this latest innovation, visit
