Acetyl-L-carnitine supplementation has been shown to benefit energy-intensive body systems such as the nervous system and the cardiovascular system, and to help counteract the age-related increase in oxidative stress and the decrease in mitochondrial efficiency that occurs with advancing years.^1-5

Acetyl-l-carnitine has wide-ranging benefits for nervous system wellness, including the central and peripheral nervous systems, and cognitive health, as well as positive mood.^6-11 It has been shown to promote peripheral nervous system comfort, support healthy mood, energy and overall well-being.^12-17

B12 Elite combines two types of cobalamin: adenosylcobalamin and methylcobalamin. These are “active” forms—meaning your body can make use of them right away.

Adenosylcobalamin helps preserve neuronal function

Leucine-Rich Repeat Kinase 2 (LRRK2) is a type of enzyme that modifies other proteins by adding phosphate groups. Inhibiting the activity of this enzyme has been associated with helping to preserve neuronal tissue.

A series of preclinical studies has shown that the adenosylcobalamin form of B12 can inhibit the activity of multiple LRRK2 variants in neurons by decreasing phosphorylation (the addition of phosphate groups to amino acids).

These studies found that adenosylcobalamin helped regulate healthy release of dopamine, a neurotransmitter that plays an important role in cognitive functions such as motor control, arousal, reinforcement and reward.

A cofactor for energy metabolism

Adenosylcobalamin is active in the mitochondria, the powerhouses of your cells. It’s required as a cofactor for the synthesis of succinyl-CoA, a compound that supports cellular energy metabolism.

Methylcobalamin for cellular health & beyond

Methylcobalamin is another neurologically active form of B12 (though in different ways than adenosylcobalamin). Methylcobalamin supports the central nervous system, and it’s essential for the replication and growth of cells.

Methylcobalamin helps to maintain already healthy homocysteine levels. Inhibiting excess levels of this compound is key to maintaining healthy cardiovascular and neurological function.

B12 for a healthy brain and more

This B12 formula combines methylcobalamin and adenosylcobalamin to offer optimal cognitive support. Want the health benefits of the full range of the B vitamins? We also offer our BioActive Complete B-Complex formula: a wide-spectrum of B vitamins for whole-body health.

Suggested Use: Dissolve one lozenge daily in mouth, ideally under your tongue

Supports a healthy inflammatory response 

A healthy response to inflammation is a crucial part of preserving robust health. A number of studies have shown the inhibitory effects of black cumin seed oil on inflammatory molecules promoting your body’s healthy inflammatory response to support whole-body health.^6,8,11,15,16

Boosts the immune system

Black cumin seed oil also supports the body’s natural defenses by encouraging optimal function of a healthy, aging immune system. It does this by supporting the vital defensive activities of immune cells that work together to bolster your immune system.^17-20

Two essential functions in one supplement

By acting on both immune and inflammatory factors, Black Cumin Seed Oil supports a healthy immune system and promotes a healthy inflammatory response.

We have spent years searching for a superior, highly bioavailable form of curcumin, one that delivers maximum health benefits so you can thrive. To do this, we needed to find a technology that protected curcuminoids during digestion and delivered more free curcuminoids per dose.

Fenugreek helps inhibit conjugation

Once in the body, curcuminoid compounds undergo conjugation, a normal chemical reaction where one compound attaches to another. This is problematic because conjugated curcuminoids do not necessarily provide the same health benefits as non-conjugated ones.^1,2

Advanced Curcumin Elite™ protects curcuminoids from conjugation by combining curcumin with galactomannans, a type of fiber derived from fenugreek seeds. Clinical and pre-clinical data shows that doing so produces 45.5 times more bioavailability and broader tissue distribution of free curcuminoids than unformulated curcumin.^3,4

In a clinical study, more than 70% of total plasma curcuminoids were still in their free form five hours after ingestion.⁴ That translates into more comprehensive whole-body health support from the curcumin supplement.

Turmerones and ginger

We’ve added several plant compounds to Advanced Curcumin Elite™ to enhance health benefits of this supplement. Standardized ginger compounds and turmerones from turmeric oil complement curcumin’s ability to help promote a healthy inflammatory response and enhance curcumin’s other health benefits as well.^5,6

Superior curcumin, responsibly sourced

The total amount of free curcuminoids delivered by standard curcumin (such as the one in our previous formulation) is low. So, we’ve made the switch to Advanced Curcumin Elite™ in order to provide our best possible curcumin supplement to our customers.

It is also worth noting that curcumin in Advanced Curcumin Elite™ is sourced from a multitude of responsible farming collectives in India. Advanced Curcumin Elite™ is then made via FenuMAT™, a patented, environmentally friendly, water-based extraction technology (no solvents or chemicals) during which it is combined with fenugreek fiber.

Cognitive health

Vitamin D is important for maintaining cognitive health and function as you age. Healthy serum vitamin D levels have been shown to correspond with better scores on cognitive health tests and better maintenance of cognitive ability in aging individuals.^1-4 

Bone and immune health

Vitamin D (along with vitamin K and essential minerals) is essential for facilitating the transport of calcium into the bone matrix. This is an important step in maintaining strong, healthy bones and teeth. Vitamin D also plays a critical role in healthy immune function.^5,6

Heart health & already-healthy blood pressure support

Vitamin D helps to regulate the body’s calcium balance while facilitating calcium absorption into the bloodstream, promotes a healthy inflammatory response, and encourages healthy endothelial function.⁷ Vitamin D also helps inhibit excess renin levels. Healthy renin levels help maintain healthy blood pressure already within the normal range.⁸

Getting enough vitamin D

This vitamin D3 supplement delivers 125 mcg of vitamin D3 as cholecalciferol per capsule. We suggest that you take a 25-hydroxy vitamin D blood test after 3 months to assess and adjust your dosage. Your optimal blood levels should be 50–80 ng/ml year-round.

Produce more ATP with D-ribose

D-ribose, a carbohydrate molecule found in every living organism, is essential in encouraging the production of ATP. In studies of healthy athletes, D-ribose supplementation has been shown to support exercise capacity and recovery. By helping to support cellular energy production, D-ribose may be especially beneficial for promoting heart health.

The vegan, non-GMO Bioenergy RIBOSE® in our D-Ribose Tablets may help support exercise endurance and cellular energy production and maintain healthy energy levels in heart and muscle tissue.

Cardio, circulatory & bone health

DHEA has beneficial cardiovascular effects. It also promotes bone health. In a randomized, double-blind, controlled trial, one year of DHEA supplementation helped increase bone mineral density in the hips of older adults and spinal bone mineral density in older women.

DHEA: usage & safety precautions

In order to develop a personalized, effective DHEA regimen, regular testing of blood levels is highly recommended to determine the proper and accurate dosage. Because of the overwhelming evidence connecting youthful levels of DHEA with healthy longevity, Life Extension suggests that most people over age 40 begin DHEA supplementation. The starting supplemental dose of DHEA for most people is 15 to 25 mg a day, though some people will require higher doses to reach youthful levels.

More facts about Enhanced Zinc Lozenges

Zinc is a trace mineral. And there’s more than one type of zinc preparation. The zinc acetate in this formula releases 100 percent of its zinc as ionic zinc (positively charged zinc ions). This is the preferred kind of zinc, because it provides enhanced seasonal immune support, encouraging a strong and healthy immune response.

How do I choose the right zinc supplement?

Our Enhanced Zinc Lozenges are peppermint-flavored and packed with zinc acetate. They have no other ingredients that could discourage the delivery of these immune-supportive, positively charged zinc ions, making this a convenient immune-support supplement.

How much zinc acetate is right for me?

One vegetarian lozenge of Enhanced Zinc Lozenges provides 18.75 mg of zinc acetate. Please note that these special lozenges are not meant for daily use: Only a few are required for seasonal immune response support. So keep a bottle close by for immediate access!

Glucosamine is often combined with chondroitin because both of these nutrients, including in combination support significant preservation of healthy joint structure and comfort.^3-6 For the convenience of our customers, we are proud to offer glucosamine as a stand-alone supplement.

This formulation combines vitamins B2 (riboflavin), B6 (pyridoxal 5’-phosphate), B12 (as methylcobalamin) and folate as L-5-methyltetrahydrofolate (L-5-MTHF).

Folate (L-5-MTHF)

Folate helps maintain homocysteine levels within the normal range, which promotes cardiovascular health.^1,7,8 Folate supports neurotransmitter synthesis as well, which is an essential part of cognitive health.⁹ People with healthy homocysteine levels have a greater chance of maintaining healthy cognitive function.^10,11

But not everyone’s body can utilize traditional folate supplements. Research shows that a large part of the population cannot convert folate to its bioactive 5-MTHF form (L-5-methyltetrahydrofolate), leaving many vulnerable to low blood folate levels (and higher-than-desired homocysteine).¹² So Homocysteine Resist delivers 8500 mcg of 5-MTHF in each capsule.

Vitamin B6 (pyridoxal 5'-phosphate)

Vitamin B6 also facilitates neurotransmitter synthesis, as well as amino acid and lipid metabolism.⁹ Traditional forms of B6 must be converted to pyridoxal 5'-phosphate before your body can use it, but Homocysteine Resist contains 100 mg of pyridoxal 5'-phosphate that’s ready to work right from the start.⁹

Vitamin B2 (riboflavin) and Vitamin B12 (methylcobalamin)

The body naturally converts vitamin B2 (riboflavin) to its riboflavin-5'-phosphate form, which it then uses for energy production.¹³ Vitamin B12 supports nerve cell growth and heart health by helping to maintain healthy homocysteine levels already within normal range.^14,15 And methylcobalamin is the form of B12 biologically active in your brain.¹⁶

Lutein & Zeaxanthin: vital for healthy vision

That's why this formula contains lutein and trans-zeaxanthin and meso-zeaxanthin, as well as alpha-carotene, another eye health carotenoid that has been associated with protection of the macula and retina.⁴ Lutein and the two types of zeaxanthin are very well-known to help preserve the health of the macula and act as defenders against excessive oxidative stress. They help keep eyes functioning well, even over time.^3,5,6

Astaxanthin: fight eye fatigue

Japanese scientists have clinically studied astaxanthin. They’ve demonstrated that 6 mg of astaxanthin supplementation daily helped promote visual sharpness and eye health.⁷

Phospholipids for carotenoids: optimal absorption

Getting these eye-healthy nutrients where you need them most is a huge part of supporting your vision health. This formula contains phospholipids, which are an integral part of every cell membrane in the body. This helps promote absorption of lutein and zeaxanthin. Good absorption is crucial for these nutrients to make it into the retina of the eye.³ 

Nutrition for night vision: C3G berry flavonoids

MacuGuard® Ocular Support with Saffron & Astaxanthin also contains an anthocyanin flavonoid extracted from European black currant berry. Cyanidin-3-glucoside encourages the regeneration of rhodopsin, a retinal compound that converts visible light to the electrical signals that reach the visual centers of the brain, especially in low-light conditions.^8,9 Rhodopsin needs to be continually regenerated, but science believes that as we age this happens less and less.¹⁰ Cyanidin-3-glucoside may help older eyes see better at night.

Vision-enhancing benefits of saffron

This formula also includes saffron extract. Multiple clinical studies have shown that supplementation with 20 mg of saffron helps support vision and retinal function, as measured both by advanced technical testing and on the Snellen eye chart that is commonly used by doctors to test vision.^11-13
