SHOP DIGESTXYM — TORNO10 APPLIED ↗ $64.00 list price · 10% off with TORNO10
HOW IT WORKS IN THE BODY

Food proteins, fats and carbohydrates each need different enzymes. Proteases break proteins into peptides, lipases act on fats and amylases act on starches. Most digestion is done by the body’s own pancreatic and intestinal enzymes; a supplemental blend is designed to add to that work at mealtimes.

WHY THIS PRODUCT IS FEATURED

A broad, meal-time starting point for readers exploring digestive comfort. Compare the label’s enzyme activities and ingredients, and remember that enzymes support digestion but do not correct an underlying digestive disorder.

SUGGESTED USE

1 capsule with a glass of water at the beginning of each meal (manufacturer suggested use). Check the current label, review your medications with a clinician, start only if appropriate, and reassess how you feel rather than increasing the dose.

Safety note: Persistent pain, unexplained weight loss or blood in the stool need medical evaluation.

HCL-XYM bottle by U.S. Enzymes
PRODUCT 02 • Stomach acidity & protein digestion

HCL-XYM™

Betaine HCl Supplement with AstraZyme®

Top 7 benefits
  1. Natural source of Betaine Hydrochloride for healthy digestive function*
  2. Supports the body’s natural ability to produce HCL*
  3. Supports optimal protein digestion and absorption of food*
  4. Creates the proper pH in which protein-digesting enzymes work best*
  5. Offers relief from occasional gas, bloating and indigestion*
  6. Helps extract vitamin B12 from food*
  7. Helps maintain healthy intestinal flora levels*
SHOP HCL-XYM — TORNO10 APPLIED ↗ $26.00 list price · 10% off with TORNO10
HOW IT WORKS IN THE BODY

Stomach acid helps unfold dietary proteins and activates pepsin, the stomach’s main protein-digesting enzyme. Betaine HCl adds acidity; pancreatic and intestinal enzymes then finish most of the work further down the tract.

WHY THIS PRODUCT IS FEATURED

Pairs with the books’ digestive-physiology chapters, which explain why symptoms alone cannot confirm low stomach acid.

SUGGESTED USE

1 capsule after each meal; 2 after a heavy or protein-rich meal if needed (manufacturer suggested use). Check the current label, review your medications with a clinician, start only if appropriate, and reassess how you feel rather than increasing the dose.

Safety note: Get medical advice first if you have reflux, gastritis, ulcers, take NSAIDs or use acid-reducing medication. Betaine HCl can irritate the digestive tract.

U.S. Enzymes product pair

Circulatory enzyme support

Fibrin-focused systemic enzymes that support healthy circulation*

NATTOXYM bottle by U.S. Enzymes
PRODUCT 03 • Circulatory support

NATTOXYM™

Targeted Systemic Enzyme · Nattokinase + Catalase

Top 7 benefits
  1. Targeted circulatory support from the enzyme nattokinase*
  2. Nattokinase helps maintain healthy circulation*
  3. Catalase helps clear hydrogen peroxide produced by enzyme activity*
  4. Supports overall immune health*
  5. Proprietary mineral base with AstraZyme® to support absorption*
  6. Delayed-release capsules protect nattokinase from stomach acid
  7. Free of fillers, artificial colors, flavors and preservatives
SHOP NATTOXYM — TORNO10 APPLIED ↗ $62.00 list price · 10% off with TORNO10
HOW IT WORKS IN THE BODY

Nattokinase is a protein-digesting enzyme from fermented soybeans (natto). Laboratory and small human studies have looked at its effects on fibrin and circulation markers; changes in markers do not show that it prevents heart attacks or removes plaque.

WHY THIS PRODUCT IS FEATURED

A companion to Understanding Arterial Health’s chapters on clotting, fibrin and circulation, not a replacement for prescribed cardiovascular care.

SUGGESTED USE

1 capsule with water on an empty stomach, 2 hours before or after a meal (manufacturer suggested use). Check the current label, review your medications with a clinician, start only if appropriate, and reassess how you feel rather than increasing the dose.

Safety note: Ask your clinician first if you take blood thinners or antiplatelet medicine, have a bleeding disorder, a history of stroke, or upcoming surgery. Not for use while pregnant or nursing without advice.

LUMBROXYM bottle by U.S. Enzymes
PRODUCT 04 • Advanced circulatory support

LUMBROXYM™

Targeted Systemic Enzyme · Lumbrokinase + Catalase

Top 7 benefits
  1. 375 FU lumbrokinase + 350 U catalase in every capsule
  2. Lumbrokinase, a fibrinolytic enzyme, helps support healthy circulation*
  3. Helps support healthy blood pressure levels*
  4. Supports cardiovascular and circulatory health*
  5. Supports longevity and overall immune health*
  6. Patented sodium alginate base in protective delayed-release capsules
  7. AstraZyme® for absorption; Non-GMO, gluten-free, no fillers
SHOP LUMBROXYM — TORNO10 APPLIED ↗ $70.00 list price · 10% off with TORNO10
HOW IT WORKS IN THE BODY

Lumbrokinase is a group of protein-digesting enzymes studied for fibrin-related activity. Early research does not show that oral products clear arterial blockages or prevent cardiovascular events.

WHY THIS PRODUCT IS FEATURED

An advanced reading companion that helps explain the difference between fibrin research and proven prevention or treatment.

SUGGESTED USE

1 capsule with water on an empty stomach, 2 hours before or after a meal (manufacturer suggested use). Check the current label, review your medications with a clinician, start only if appropriate, and reassess how you feel rather than increasing the dose.

Safety note: Needs clinician or pharmacist review of medications, bleeding history and upcoming procedures. Do not combine with nattokinase or other clot-related supplements unless supervised.

U.S. Enzymes product pair

Systemic & antioxidant enzymes

Full-body protease support and antioxidant enzymes for healthy aging*

THERAXYM bottle by U.S. Enzymes
PRODUCT 05 • Full-body systemic support

THERAXYM™

Full Body Systemic Support · 10 proteolytic enzymes

Top 7 benefits
  1. 10 full-spectrum, plant-based proteolytic enzymes for full-body support*
  2. Supports immune system health and function*
  3. Supports cardiovascular health*
  4. Supports musculoskeletal health and full-body performance*
  5. Supports respiratory system health*

  7. Informed Sport Certified: tested for over 250 banned substances
SHOP THERAXYM — TORNO10 APPLIED ↗ $72.00 list price · 10% off with TORNO10
HOW IT WORKS IN THE BODY

Proteases break the bonds that hold proteins together. Taken by mouth, most of this activity happens in the digestive tract; how much reaches the bloodstream and produces meaningful whole-body effects is still being studied.

WHY THIS PRODUCT IS FEATURED

Shows the difference between a plausible biochemical mechanism and outcomes proven in rigorous human trials.

SUGGESTED USE

1 capsule with water on an empty stomach, 2 hours before or after a meal (manufacturer suggested use). Check the current label, review your medications with a clinician, start only if appropriate, and reassess how you feel rather than increasing the dose.

Safety note: Ask your clinician first if you take blood thinners, are preparing for surgery, or are pregnant or nursing. Stop if you notice stomach upset or an allergic reaction.

YOUTHXYM bottle by U.S. Enzymes
PRODUCT 06 • Antioxidant enzymes & healthy aging

YOUTHXYM™

Antioxidant Enzyme Blend · SOD + Catalase + ALA

Top 7 benefits
  1. High levels of the antioxidant enzymes superoxide dismutase (SOD) and catalase*
  2. Two diverse sources of superoxide dismutase*
  3. Supports longevity*
  4. Supports immune health*
  5. Promotes cognitive well-being and helps relieve daily stress*
  6. 170 mg alpha lipoic acid + 50 mg AstraZyme® to enhance enzyme actions*
  7. Non-GMO, gluten-free; no fillers, artificial colors, flavors or preservatives
SHOP YOUTHXYM — TORNO10 APPLIED ↗ $70.00 list price · 10% off with TORNO10
HOW IT WORKS IN THE BODY

Superoxide dismutase (SOD) converts superoxide radicals into hydrogen peroxide and oxygen; catalase then breaks hydrogen peroxide into water and oxygen. The body makes its own SOD, and the effect of oral forms depends on the formulation.

WHY THIS PRODUCT IS FEATURED

Connects the cellular-aging chapters of The Science of Aging From the Inside Out with real antioxidant chemistry, without promising rejuvenation or a longer lifespan.

SUGGESTED USE

1 capsule on an empty stomach, 2 hours before or after a meal (manufacturer suggested use). Check the current label, review your medications with a clinician, start only if appropriate, and reassess how you feel rather than increasing the dose.

Safety note: Not proven to reverse aging. Check with your clinician if you are pregnant, nursing, managing blood sugar or taking prescription medicines.
