What is inside
each active formula.

as fully-reacted magnesium bisglycinate

An essential mineral your body uses in 300+ enzymatic reactions.*

Magnesium is a required cofactor for hundreds of enzymes governing energy production, nerve signaling, and muscle function. We use the bisglycinate (chelate) form — magnesium bound to the amino acid glycine — which is absorbed efficiently and is gentle on digestion compared with cheaper oxide salts.

molecularly distilled fish oil concentrate

The long-chain fatty acids that build every cell membrane.*

EPA and DHA are the two long-chain omega-3 fatty acids the body incorporates into cell membranes throughout the brain, eyes, and cardiovascular system. Omega-3 Priority supplies 400 mg EPA and 200 mg DHA per softgel serving from a concentrated fish oil source.

Kaneka Ubiquinol™ — the active, reduced form

The spark plug of cellular energy production.*

Coenzyme Q10 sits at the heart of the mitochondrial electron-transport chain, where cells generate ATP — and it doubles as a lipid-phase antioxidant. We use ubiquinol, the already-reduced form that circulates in the blood and that cells use directly, so the body doesn't have to convert it — a meaningful edge as natural CoQ10 levels and conversion efficiency decline with age.

as cholecalciferol — the form your skin makes from sunlight

The sunshine vitamin that supports immune, bone and muscle health.*

Vitamin D3 (cholecalciferol) is the same form your skin synthesizes from sunlight and is commonly used to help maintain vitamin-D status. Vitamin D supports immune function, bone health and normal muscle function.*

Turmeric standardized to 95% curcuminoids + BioPerine®

A standardized active from turmeric root.*

Curcuminoids are the bioactive polyphenols in turmeric studied for their role in antioxidant activity and a healthy inflammatory response.* Turmeric Complex Priority combines turmeric root, 95% curcumin extract and BioPerine® black-pepper extract to support absorption.*

the amino-acid fuel behind the Lift formulas

The amino acid upstream of your alertness neurotransmitters.*

L-phenylalanine is an essential amino acid the body converts into tyrosine, a precursor to dopamine and norepinephrine. The Lift formulas pair 600 mg phenylalanine with B vitamins and caffeine to support mental energy and focus.*

the phospholipid concentrated in neuronal membranes

A building block of the membranes around your brain cells.*

Phosphatidylserine (PS) is a phospholipid found in cell membranes, including neuronal membranes, where it helps support normal cell-to-cell signaling.* PS Priority provides 100 mg per capsule to support memory and cognitive function.*

Camellia sinensis standardized to 50% EGCG

The most-studied antioxidant catechin in green tea.*

EGCG (epigallocatechin-3-gallate) is a well-known catechin in green tea and contributes to the leaf's antioxidant activity. V-Guard 2 uses a concentrated Camellia sinensis leaf extract standardized to 50% EGCG and 90% polyphenols.

glucosamine HCl — connective-tissue support

A naturally occurring amino sugar involved in joint structure.*

Glucosamine is an amino sugar involved in glycosaminoglycans and proteoglycans, components of the body's normal connective-tissue matrix. Joint Decision supplies glucosamine HCl on its own, while Total Joint Complex combines it with chondroitin, MSM and botanicals.

fat-soluble B1 with the dipeptide carnosine

Nutrients that support healthy aging and glycation balance.*

Glycation is a normal biochemical process in which sugars can bind to proteins. Ageless Priority combines benfotiamine, a fat-soluble form of vitamin B1 that supports healthy glucose metabolism, with carnosine and alpha-lipoic acid for antioxidant support.*

as choline dihydrogen citrate

The dietary nutrient your brain turns into acetylcholine.*

Choline is an essential nutrient and the direct precursor to acetylcholine, a neurotransmitter central to memory and learning. Our Mind drink mix delivers a generous gram of it as readily-usable choline dihydrogen citrate, surrounded by the synergistic B-vitamins the Durk & Sandy 'Designer Food' approach paired with it; Productive Sleep includes choline as well.

water- and fat-soluble (calcium ascorbate + ascorbyl palmitate)

The classic antioxidant in two complementary forms.*

Vitamin C is a water-soluble antioxidant and an essential cofactor the body needs to build collagen and to support normal immune function.* Our Vitamin C² pairs buffered calcium ascorbate with ascorbyl palmitate — a fat-soluble form — so the vitamin can work in both the watery and the lipid compartments of the body; V-Guard 2 layers it with green-tea antioxidants.
