Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for providing NAD+ precursors like nicotinamide riboside (NR), nicotinic acid riboside (NAR), nicotinic acid mononucleotide (NaMN), and nicotinamide mononucleotide (NMN) are inefficient in maintaining stable levels in liquid formulations, leading to hydrolysis and suboptimal bioavailability.

Innovation Solution

Encapsulating these compounds in alginate beads or prilling them with edible oils and waxes to form stable wax prills, which reduce hydrolysis when added to water, ensuring consistent bioavailability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If NAD+ precursors are provided in liquid formulations, then bioavailability is improved, but hydrolysis occurs leading to instability

Engineering Contradiction:

Improvestability of NAD+ precursorsVSAvoidhydrolysis of NAD+ precursors

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The patent applies preliminary action by pre-encapsulating NAD+ precursors in alginate beads or coating them with waxes and oils before administration. This preliminary encapsulation protects the compounds from hydrolysis during storage and transport, allowing them to remain stable until they reach the target environment where they are needed for absorption and conversion to NAD+.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses alginate beads, waxes, and oils as intermediary materials that mediate between the NAD+ precursors and the aqueous environment. These intermediaries protect the precursors from direct contact with water that would cause hydrolysis, while still allowing controlled release and absorption of the active compounds when needed.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If NAD+ precursors are administered without encapsulation, then absorption is faster, but hydrolysis reduces bioavailability

Engineering Contradiction:

Improvebioavailability of NAD+ precursorsVSAvoidhydrolysis during administration

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The patent employs flexible shells and thin films by using alginate beads as encapsulating shells and wax/oil coatings as thin film layers. These flexible barriers protect the NAD+ precursors from hydrolysis while allowing controlled release through diffusion or degradation of the shell/film, enabling both protection during administration and release for absorption.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The patent applies parameter changes by modifying the physical state and chemical environment of NAD+ precursors through encapsulation. The alginate beads and wax coatings change the solubility parameters and hydrolysis rate constants, allowing the compounds to remain stable in dry or lipid environments while still being absorbable when they reach the appropriate physiological conditions.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If encapsulation methods are used, then stability is improved, but manufacturing complexity increases

Engineering Contradiction:

Improvestability of formulationsVSAvoidencapsulation process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies self-service by utilizing the natural gel-forming properties of alginate that automatically encapsulate liquid formulations containing NAD+ precursors. The alginate solution self-assembles into beads through gelation, eliminating the need for complex encapsulation equipment. Similarly, the wax and oil coatings leverage natural coating processes rather than requiring sophisticated application systems.

Inventive Principle:

Principle #25Self-service
