ALPHA LIPOIC ACID SUPPLEMENTS- Why Amino Acids? Acetyl L-Carnitine (aka ALCA + ALC) & Alpha Lipoic Acid (ALA) support healthy blood vessels. Carnitine is only found in meat, which is why it’s important for vegans and vegetarians to supplement.

ANTI AGING- Amino Acids help build the protein cells in our eyes, brain, hair, blood vessels, and muscles, which stabilizes cellular decline from old age, poor diet, and injury.

HEALTHY BODY & MIND- ALCAR and ALA support nootropic functions by increasing focus, memory, and alertness. They also boost metabolism and burn fat, increasing energy, and reducing chronic fatigue.

How much energy do you have? - Alpha Lipoic Acid is a powerful antioxidant molecule found in all cells. It is needed to convert carbohydrates (glucose) into energy as ATP. Also known as ALA, it recycles other antioxidants like CoQ10 and glutathione. ALA modulates nitric oxide metabolite activity and promotes healthy blood circulation and nerve function unimpeded by neuropathy.

Superior Absorption Of Pure R-ALA - We only use pure R-Alpha Lipoic Acid, because it is the ONLY active lipoic acid form found in nature and foods. Don't be tricked by amounts like 600mg or even 1000mg of "plain" powder ALA in other supplements - they mainly contain the S-ALA synthetic and inactive (form) which will not work. Our liposomal technology protects R-ALA in sheaths of membrane phospholipids which enhances the otherwise poor bioavailability of ALA.

Fat Metabolism, Cognition And Athletic Performance - Acetyl-L-Carnitine also known as ALC or ALCAR, is an antioxidant derivative of l-carnitine. It's role is to transport fat (as fatty acids) into mitochondria to sustain energy production in all cells, especially brain and muscle. An increase in cellular energy can support cognition, memory formation and muscle endurance.

Mason Natural Co Q10 with L-Carnitine are formulated to give a dose of Co Q10 and L-Carnitine which may help support normal, healthy cardiovascular function. L-carnitine is an important partner of both CoQ10 and essential fatty acids.

Our Co Q10 with L-Carnitine softgels formula provide important antioxidants that may help promote cardiovascular health contains 30 mg of Co Q10, 250 mg of L-Carnitine and 34 mg of Vitamin E.

Co Q10 may provide potent antioxidant protection within cells from toxic free radical compounds. Co Q10 is popular with people who may be taking statin drugs as these drugs tend to deplete CoQ10 levels within the body. Certain organs have very large requirements of energy and sufficient amounts of Co Q10 is vitally important. These major organs including liver, lungs, kidneys and heart and brain function.
