Magnesium is involved in over 300 enzymatic processes — turning food into usable energy, repairing muscle tissue, regulating the nervous system, keeping the heart muscle steady. Most adults don't get enough. The body registers the shortfall as flat afternoon energy, muscles that stay tense after training, a mind that won't quite switch off, and sleep that never fully settles.

The formulation

Two capsules deliver 300mg of magnesium bisglycinate (150mg per capsule) — fully chelated for absorption without the digestive upset of cheaper magnesium oxide or citrate. Bound to glycine, an amino acid that does its own work in the body rather than acting as a passive carrier.

Why ours

300mg per serving is 2.5x the dose of most premium peers — and bisglycinate is the form clinical research consistently uses. No fillers, no proprietary blends, no rounding down on the dose.

How to take it

Two capsules in the evening, ideally 30–60 minutes before bed. If you train in the morning or want the energy support through the day, split one capsule morning and one evening.

What to expect

Calmer sleep onset and reduced muscle tension usually within the first week. Steadier daytime energy and faster recovery between training sessions build over 2–4 weeks.

Most adults are deficient in vitamin D — particularly through the winter months when the sun is too low in the sky for the skin to make any. Levels drop, and with them goes immune resilience, bone strength, and mood.

The formulation

Each capsule delivers 2,500 IU of vitamin D3 — the form your body produces from sunlight, and the form clinical research consistently uses. Paired with Beet Root for the circulatory support that helps fat-soluble vitamins reach the tissues that actually need them.

Why ours

Most D3 supplements stop at 1,000 IU — a maintenance dose for people who already have adequate levels. 2,500 IU is calibrated for the deficiency most adults actually have, particularly through the darker half of the year.

How to take it

One capsule daily with a meal containing fat for best absorption.

What to expect

Energy and mood shifts often appear within 4–6 weeks; immune resilience builds over a full winter season of consistent use.

Your heart and brain depend on EPA and DHA — and most diets don't deliver enough. The body responds with inflammation that builds quietly: stiff joints, cognitive fog, slower recovery, mood shifts.

The formulation

Each 2,000mg capsule delivers 1,000mg EPA + 500mg DHA — a 75% active omega-3 concentration, compared to the 30–35% found in most premium fish oils. Sourced from wild-caught anchovy, sardine, and mackerel. Molecularly distilled for low mercury and oxidation control.

Why ours

Most omega-3 supplements lead the label with "fish oil 1,000mg" — which is total oil weight, not active omega-3 content. A 1,000mg softgel at 30% concentration gives you 300mg of what actually matters. We list EPA and DHA separately, because those are the molecules the research is built on.

How to take it

One to three capsules daily with food. Take three for the 4,500mg daily dose used in cardiovascular and cognitive research.

What to expect

Most users notice mood, joint, and recovery shifts within 6–12 weeks.

Persistent fatigue, brain fog, low mood, tingling in hands or feet — roughly 1 in 6 adults is B12 deficient, and most don't realize it. The risk rises if you're vegetarian, vegan, over 50, on metformin, or on acid-reducing medication.

The formulation

1,000mcg of methylcobalamin — the active, methylated form your body uses directly, without conversion. Paired with Beet Root for the circulation that helps B12 reach the nervous system and the red blood cells it's most needed for.

Why ours

Most B12 supplements use cyanocobalamin — a cheaper synthetic form that requires your body to convert it (and dispose of a cyanide molecule in the process). Methylcobalamin skips the conversion entirely and is the form preferred for anyone with absorption or methylation challenges.

How to take it

One capsule daily, with or without food. Vegan-friendly.

What to expect

Energy and clarity often shift within 2–4 weeks of consistent daily use.

The kind of stress that doesn't go away when the workday ends — that lingers in your shoulders, your sleep, your sense of being slightly on edge — is what ashwagandha has been used for over 3,000 years.

The formulation

An 11:1 concentrated root extract: 5,940mg of dry root concentrated into a two-capsule serving, standardized to 5% withanolides. Paired with Spirulina for the whole-food minerals and amino acids the adrenal system depends on under sustained stress.

Why ours

Most ashwagandha on the market is raw root powder at 1–2% withanolides. Our 5% standardization matches the branded extracts that command a premium price point.

How to take it

Two capsules daily, ideally with food. Not recommended during pregnancy.

What to expect

Calmer background tone within 2–4 weeks; sleep and recovery shifts often follow by week 6.

Bloating, irregular digestion, low energy and mood — they all trace back to gut microbial balance. The challenge is that most probiotics on store shelves are partly or fully dead by the time you take them, regardless of what the label says.

The formulation

Three clinically-studied strains: Lactiplantibacillus plantarum KABP 022, Lactiplantibacillus plantarum KABP 023, and Pediococcus acidilactici KABP 021 — delivered at the doses used in human clinical research. Paired with Inulin prebiotic fiber to feed the beneficial bacteria already in your gut.

Why ours

The probiotic market competes on CFU count — 50 billion, 100 billion — without telling you which strains, at what dose, or backed by what research. We use named, clinically-studied strains at clinical doses. Higher CFU counts of unstudied strains aren't more effective; they're just bigger numbers.

How to take it

One capsule daily, ideally on an empty stomach. Refrigerate after opening.

What to expect

Digestion shifts often appear within 1–2 weeks; mood and energy changes typically follow over 4–6 weeks.

Joint stiffness, slow recovery — the wear that builds with age and activity. Turmeric is one of the most-researched botanicals for supporting a healthy inflammatory response — but its active compounds are notoriously poorly absorbed alone.

The formulation

A 95% curcuminoid extract — the active compound complex, concentrated. Paired with 4.6mg of Piperine (black pepper extract), which has been shown to increase curcumin absorption by up to 2,000% compared to curcumin taken alone.

Why ours

Most turmeric supplements use raw turmeric root powder at 3–5% curcuminoid content — meaning you're getting a small fraction of the active compound, and most of that passes through unabsorbed. 95% extract with Piperine is the combination clinical research actually uses.

How to take it

Two capsules daily with a meal containing fat for best absorption.

What to expect

Joint comfort and recovery shifts often appear within 4–8 weeks.

Run-down immunity, slow-healing skin, hormonal swings, loss of taste or smell — zinc supports all of it, and most adults don't get enough. But long-term zinc supplementation without copper actually depletes copper levels and creates new problems.

The formulation

30mg of elemental zinc as zinc citrate — well-absorbed and gentle on the stomach. Balanced with 5mg of copper to prevent the depletion that unbalanced zinc supplementation causes. Paired with Spirulina for the trace minerals and amino acids the immune system relies on.

Why ours

Most zinc supplements skip copper entirely, which is fine for short-term immune use but problematic for daily-use customers. Our zinc-to-copper ratio is balanced within the range nutrition research recommends for long-term supplementation.

How to take it

One capsule daily, ideally with food. Take separately from iron.

What to expect

Immune resilience builds within 2–4 weeks; skin and recovery shifts often follow.

Your heart, brain and muscles are your hardest-working tissues, and they run on energy made inside your cells. CoQ10 is part of how your mitochondria make that energy, and the body's own production declines from your 30s onward.

The formulation

200mg of ubiquinol — the active, reduced form of CoQ10 the body uses directly, without conversion. Paired with beet root, a natural source of dietary nitrates the body uses to support healthy blood flow.

Why ours

Most CoQ10 supplements use ubiquinone — the oxidized form that requires the body to convert it before use. Ubiquinol skips the conversion step entirely and is better absorbed, particularly for anyone over 40, whose conversion efficiency tends to decline with age.

How to take it

One capsule daily with a meal containing fat for best absorption.

What to expect

Energy and recovery shifts often appear within 4–8 weeks; give it three months for the full picture.

Calcium in your bones strengthens you. Calcium in your arteries doesn't. Vitamin K2 is the nutrient that tells calcium where to go — and the form matters more than almost any other supplement decision you'll make.

The formulation

120mcg of K2 as MK-7, the longer-acting form with a half-life of roughly 3 days. Paired with Beet Root for the cardiovascular synergy that supports both arterial flexibility and circulation. Pairs naturally with our Vitamin D3 — calcium needs both directions.

Why ours

Most K2 supplements use MK-4, which has a half-life of about one hour and requires multiple daily doses to maintain blood levels. MK-7 is the form used in the cardiovascular and bone density research that makes K2 worth taking in the first place. Read the label on any K2 product before you buy — most won't say.

How to take it

One capsule daily with a meal containing fat. Stack with D3 for full effect.

What to expect

K2 works at the structural level — benefits are cumulative over months rather than days.

NAD⁺ is the coenzyme your cells need for energy, repair, and resilience — and levels decline measurably from your 30s onward. NMN is the most direct way to support it: it's the precursor your body uses to make NAD⁺.

The formulation

Two 300mg capsules deliver the 600mg daily dose used in human research, in ≥99.9% purity β-NMN — the active form. Powered by Uthever®, an NMN ingredient backed by peer-reviewed clinical trials in humans.

Why ours

Uthever® is the NMN ingredient used in the published human study showing a 38% NAD⁺ increase in 60 days (Uthever's study data). Most NMN on the market is generic, unverified, and sold without published human data — yet often priced the same as the clinically studied version.

How to take it

Two capsules in the morning, with or without food. Pairs naturally with our Resveratrol.

What to expect

Most users notice energy, sleep quality, and recovery shifts within 4–8 weeks of daily use.
