Rutin is a type of polyphenol called a flavonoid glycoside. It’s composed of quercetin and the disaccharide rutinose. It’s also called rutoside, quercetin-3-O-rutinoside and sophorin. While it’s found in a wide variety of plants, including citrus, foods with the highest concentrations of rutin include capers, black olives, buckwheat, and asparagus. The most common use of rutin has been for supporting healthy veins. But it does much more.

Apigenin belongs to the flavone class of polyphenol compounds. It is one of the more common flavones in the diet, found in many fruits and vegetables, including celery and parsley. It’s also found in high amounts in the flowers used to make chamomile tea.

β-Hydroxy-β-Methylbutyrate (HMB) is a metabolite of l-leucine (an essential amino acid). As we get older, muscle size, strength, and performance decline. This can occur even if we continue to exercise. HMB has been used as an ergogenic substance (i.e., something that supports improved sports performance) for more than 20 years, with most of the research focused on supporting muscle performance and helping muscles age better. 

Rosemary is a member of the mint family. Its common name derives from Latin and translates as “dew of the sea,” because it thrives close to the coast in dryer areas throughout the Mediterranean. It was used as a spice and folk medicine by Egyptians, Greeks, and Latin cultures. While rosemary contains a range of health-supporting polyphenols, including carnosol, carnosic acid, and rosmarinic acid, our main interest was in a triterpene in rosemary called ursolic acid, which supports muscle performance.

Kaempferia parviflora is found in the upper northeastern regions of Thailand. It is commonly called black ginger, because of the intense purple-black color and similar shape of the roots to ginger. The traditional use has been as a health tonic and energy enhancer leading to it sometimes being called “Thai ginseng.” The novel active constituents are polymethoxyflavonoids polyphenols. 

Theobroma cacao can be translated as chocolate, food of the gods. This tree is native to the tropical regions of the Americas. The beans are the source of the cocoa used to make chocolate. But this extract is more than simply a pleasure for our tastebuds. Over the past decade chocolate has had a blossoming reputation as being heart healthy. As it turns out, it might also be good for our mitochondrial structure and function.

Vitamin K is a family of structurally similar, fat-soluble vitamins. The two main members of the family are vitamin K1 and K2. Our interest in vitamin K was prompted when looking for compounds that might be able to rescue mitochondrial performance. This led us to source vitamin K2, ultimately as MK-7. 

The main role of vitamin B3 is to make NAD molecules. This is important because the NAD molecule sits at the crossroads of mitochondrial energy production (i.e., ATP), cellular repair and signaling, and cellular defenses. Unfortunately, NAD+ levels decrease with age. This is the bad news. The good news is that there are strategies that can be used to make more NAD+. One of these is vitamin B3.

L-tryptophan is an essential amino acid. This means the body cannot synthesize it: it must be obtained from the diet. It’s been known for decades that L-tryptophan has niacin equivalent activity in the body (i.e., we can make NAD⁺ molecules from it). L-tryptophan is unique because it’s the only way to build NAD⁺ that doesn’t start from vitamin B3. It does this by a de novo synthesis pathway, which creates a niacin molecule through a series of biological reactions. So, L-tryptophan’s inclusion would seem to be a natural fit in a formulation that wants to support boosting NAD⁺. 

BioVin® is a premium quality grape extract made from the juice, seeds, and skins of red grapes grown in France. It's rich in both trans-resveratrol and grape polyphenols.

Cinnamon is one of the world's oldest spices. Along with pepper and ginger, it was a big part of the spice trade between Asia and Europe. Cinnamon trees are native to India, Sri Lanka, Indonesia, and Burma. What we think of as cinnamon comes from the inner bark of several different tree species from the genus Cinnamomum. 

Ashwagandha is an Ayurvedic herb often referred to as “Indian ginseng.” Within this system of it was classified as a general tonic and strength promoting. Its uses included infusing energy and vigor in circumstances characterized by exhaustion or a lack of physical energy. 

Dietary polyphenols are a family of plant compounds found in common foods including fruits, vegetables, nuts, chocolate, coffee, and tea. These compounds play important roles in the plant kingdom, protecting plants from infections, pests, UV irradiation from the sun, oxidative stress, and toxic metals and chemicals.

The salvage pathway is used to produce NAD⁺ from nicotinamide molecules. Whether the source of the nicotinamide is vitamin B3 (as niacinamide), newer nicotinamides (e.g., nicotinamide riboside [NR], nicotinamide mononucleotide [NMN]), or molecules in food that get broken down during digestion into nicotinamide, the salvage pathway turns them into NAD⁺ in our tissues.

Most organisms have several alternatives for producing the NAD⁺ molecule. In humans, there are three major NAD⁺ biosynthesis pathways: the De Novo Pathway, starting from the essential amino acid L-tryptophan; the Preiss-Handler pathway, using niacin (nicotinic acid); and the Salvage Pathway from niacinamide (nicotinamide). In this article, we’ll be covering the De Novo Pathway.

In this article we’ll be covering the “big picture” when it comes to NAD. We’ll be doing a deeper dive on specific topics we introduce in this article in subsequent articles in this series. As you go through this series of articles please keep in mind that, like other molecules in the body, NAD⁺ is a means to an end. We don’t care about NAD⁺ on its own; we care about it because of what it allows cells to do. 

The amount of time we live is called lifespan. The length of time that a person is healthy and functional—not just alive—is called healthspan. Scientific understanding in these areas is advancing rapidly. Below are 12 things the collective thinks will help on your journey to a longer healthier you. 

Choosing the optimal dose for a given ingredient in our formulations is a critical and nuanced topic, so we want to share a bit about the principles that help guide our decisions at Neurohacker. Our principles derive from complexity science—the science of complex adaptive systems—and guide how we factor research and approach formulation and dosing. They take into consideration scientific evidence on the change in effect caused by differing levels of exposure (i.e., the dose-response relationship), but they do this in a way that honors complexity.
