Arthur Andrew Medical
Arthur Andrew Medical was founded on a very simple principle: creating products that simply deliver results. The foundation was laid with nutritional supplements based on enzymes and probiotics, and they have since expanded into other areas to provide the most advanced product line possible.
Arthur Andrew Medical is not a company that simply launches new products based on trends or hype. They invest countless hours in developing products and formulas they are proud of and are certain will actually deliver results.

About Arthur Andrew Medical
Arthur Andrew Medical (AAM) is an American enzyme and probiotics specialist based in Arizona, founded in 2007. AAM is known for standardised, high-dose enzyme formulas in which each product is measured in functional activity units (FU, SPU, GDU, HUT, LU) — not just in milligrams. We select AAM for those looking for targeted enzyme supplementation alongside mainstream brands.
What is Neprinol used for?
Neprinol AFD is a systemic enzyme formula from AAM with serrapeptase, nattokinase, lipase, protease, papain, bromelain and rutin. Studied for circulation and fibrin balance.
How do you use it?
Dosage
2-6 capsules per day, divided over 2 moments. Start low, build up.
When to take
Take on an empty stomach — at least 30 minutes before or 2 hours after a meal — so that the enzymes act systemically rather than in food digestion.
Frequently asked questions
What is AAM Neprinol?
Neprinol AFD is a systemic enzyme formula from AAM with serrapeptase, nattokinase, lipase, protease, papain, bromelain and rutin. Studied for circulation and fibrin balance. Part of Arthur Andrew Medical's enzyme and probiotics range.
How does AAM differ from other enzyme brands?
AAM standardises its products in functional activity units (FU, SPU, GDU and so on) rather than just milligrams. That gives a more reliable picture of what a capsule actually does.
How long do I need to use Neprinol to notice an effect?
Digestive enzymes: effect at the meal itself. Systemic enzymes (such as nattokinase, serrapeptase): often 4-8 weeks before a noticeable effect.
Can I combine AAM products with other supplements?
Digestive enzymes combine well with probiotics. Systemic enzymes: not with blood thinners without consulting a doctor.
Is Neprinol safe for long-term use?
Digestive enzymes are generally safe for long-term use. For systemic enzymes: always consult a doctor if you are having surgery or use blood thinners.
Does Neprinol contain allergens?
See the product label for the exact ingredients. AAM generally provides transparent allergen information per formula.
