What Are Systemic Enzymes and Who Should Take Them?
Systemic enzymes are proteolytic (protein-digesting) enzymes taken on an empty stomach so they can be absorbed into the bloodstream rather than used for digestion. Once circulating, they help break down excess fibrin, support healthy inflammation response, and assist with tissue repair throughout the body.
The most common systemic enzymes include nattokinase and serrapeptase (fibrinolytic enzymes that support circulation), bromelain and papain (plant enzymes from pineapple and papaya), and pancreatic enzymes like trypsin and chymotrypsin. People often use systemic enzymes for joint comfort, post-exercise recovery, cardiovascular support, sinus health, and general inflammation management.
How to Choose the Right Systemic Enzyme Supplement
Key Enzymes to Look For
For circulation and cardiovascular support, prioritize nattokinase (measured in FU—fibrin units) and serrapeptase (measured in SPU—serratiopeptidase units). Look for nattokinase at 2,000-4,000 FU minimum and serrapeptase at 40,000-120,000 SPU. For joint and muscle support, bromelain (measured in GDU) and papain work well alongside anti-inflammatory herbs like boswellia and turmeric. Comprehensive formulas like Wobenzym N include multiple enzymes for broad-spectrum support.
Delivery Method Matters
Enteric coating or delayed-release capsules are important because enzymes are proteins that can be destroyed by stomach acid. Products with protective coatings (like Wobenzym N, Solaray, or Doctor’s Best Serrateric) ensure more enzymes reach the small intestine for absorption. Standard capsules should be taken on a completely empty stomach—at least 1 hour before or 2 hours after meals.
What to Avoid
Skip products that don’t list enzyme activity units (FU, SPU, GDU) and only show weight in milligrams—enzyme potency matters more than weight. Avoid formulas with unnecessary fillers, artificial colors, or additives. If you’re vegetarian, check for pancreatic enzymes which are animal-derived; plant-based alternatives include Vitalzym and formulas using Serrazimes instead of serrapeptase.
Side Effects and Precautions
Most people tolerate systemic enzymes well, but some experience mild digestive upset, especially when first starting. Taking enzymes on an empty stomach minimizes this. Nausea is occasionally reported—if it occurs, try reducing the dose and gradually increasing.
Important: Do not take systemic enzymes if you’re on blood thinners (warfarin, aspirin, Plavix) or have bleeding disorders—nattokinase and serrapeptase have blood-thinning effects. Discontinue use 2 weeks before surgery. Pregnant or nursing women should consult a healthcare provider before use. Those with soy allergies should choose soy-free nattokinase options like Toku Flow.
FAQs
How long does it take for systemic enzymes to work? Most people notice benefits within 2-4 weeks of consistent use, though some report feeling effects within days. For joint and inflammation support, allow 4-8 weeks for full benefits. Results vary based on individual factors and the specific concern being addressed.
When is the best time to take systemic enzymes? Take systemic enzymes on an empty stomach—ideally first thing in the morning or 2 hours after your last meal before bed. This ensures the enzymes are absorbed into the bloodstream rather than used for digestion. Most products recommend 1-2 times daily.
Can I take systemic enzymes with digestive enzymes? Yes, but take them at different times. Systemic enzymes should be taken on an empty stomach for absorption into the bloodstream, while digestive enzymes are taken with meals to aid food breakdown. Some products like Vitalzym are designed to provide both benefits.
Are systemic enzymes safe for long-term use? Yes, systemic enzymes have a strong safety profile for long-term use. Products like Wobenzym N have been used daily for decades in Europe. However, those on blood thinners or with bleeding disorders should avoid them, and it’s wise to cycle off 2 weeks before any scheduled surgery.
What’s the difference between nattokinase and serrapeptase? Both are fibrinolytic enzymes but work differently. Nattokinase (from fermented soybeans) specifically breaks down fibrin and supports blood flow. Serrapeptase (originally from silkworm bacteria) breaks down non-living protein tissue and is often used for sinus and respiratory support. Many formulas combine both for complementary benefits.
Can systemic enzymes help with post-workout recovery? Yes, proteolytic enzymes like bromelain and those in Wobenzym N have been studied for reducing muscle soreness and speeding recovery after exercise. They work by supporting the body’s natural inflammation response and clearing damaged tissue proteins.
Final Verdict
For most people, Wobenzym N is our top recommendation—it’s the most clinically studied systemic enzyme formula available, combining multiple enzymes with the antioxidant rutin in a proven enteric-coated tablet. The 800-tablet bottle provides excellent long-term value.
If you’re specifically seeking high-potency serrapeptase, Zazzee’s 120,000 SPU delayed-release formula delivers the strongest dose at a competitive price. For budget-conscious buyers wanting reliable nattokinase, Luma Nutrition offers solid quality without breaking the bank.
Those who prefer vegetarian formulas should consider Vitalzym Original, while anyone wanting the convenience of multiple fibrinolytic enzymes in one product will appreciate Doctor’s Best Natto-Serra or the Spike Detox 3-in-1 combo.
