HelloPharmacist Scorecard of Maximum L+Z by ProCaps Laboratories

Four independent checks of what is known — a summary of the available information, not a grade of the product itself.

Evidence for Intended Use
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

The stated purpose hasn't been mapped to our evidence data yet.

Why this rating?
  • We haven't mapped this product's purpose to our evidence data yet — it'll be graded on the next content refresh.

Why this rating?
  • The label discloses an exact amount for 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.
Known Interaction Concern
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 2 matched ingredients can interact with medications — Zeaxanthin.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.
Safety Information

Suggested/Recommended/Usage/Directions

Suggested Use Consume one or more capsules daily or as recommended by a health care professional. Since lutein and zeaxanthin are fat soluble, they are best absorbed when consumed with foods or meals containing a small amount of fat or oil.

Formula

12 mg Lutein 6 mg Zeaxanthin

Andrew Lessman's Maximum L+Z is an ultra-high potency blend of Lutein and Zeaxanthin ( L + Z), two dietary ingredients that physicians and experts consider to be critical for eye health. Diets rich in L + Z have long been associated with superior visionand eye health. L + Z are most highly concentrated in the retina and macula of the eye where their unique molecular structure allows them to protect these delicate tissues from high-energy radiation and oxidation. Their concentration in the macula is so high that they provide both its color and its name, since in Latin the macula is called the macula lutea or yellow spot. L + Z are also referred to as "Optical Pigments," since they also play a key role in the eye's visual systems promoting visual acuity (sharpness of vision), as well as visual processing speed. Zeaxanthin also affords enhanced protection to the macula due to extremely high concentrations at the center of the retina. In short, L + Z are at the top of any list of dietary ingredients that protect our eyes from a lifetime of normal age-related changes. L + Z also protect the skin, but it is the brain where substantial recent research has shown Lutein to be associated with superior cognitive function, memory and verbal fluency with age. The body cannot make L + Z and the typical American diet provides so little that supplementation remains the only viable option of ensuring the vital protection these critical nutrients provide to our eyes, brain and skin.

Antidiabetes Drugs

Theoretically, taking zeaxanthin with antidiabetes drugs might increase the risk of hypoglycemia.
In an animal diabetic model, zeaxanthin has hypoglycemic effects. However, population research has found that increasing intake of dietary zeaxanthin plus lutein does not decrease the risk of developing type 2 diabetes.
