Seeking Health, Multivitamin One, 45 Caps

How to Use

Take 1 capsule after a protein-based breakfast on days you need additional cognitive support, healthy energy, or mood support.†

When to Take It

• Before travel — support your body’s defenses when your routine is disrupted
• Before heavy exercise — provide the nutrients your body needs under physical demand
• Before high-stress work days — support your body during demanding moments

When to Skip It

On days where you’re taking it easy, feeling good, and not needing additional energy or healthy mood support—skip it. This multivitamin is designed for as-needed use. Listen to your body.

Stacking — Best Used With

• Optimal Electrolyte — foundational hydration and mineral support
• Fish Oil — omega-3 fatty acids to complement your daily nutrient foundation

Sensitivity note: If you take Multivitamin One periodically on an as-needed basis and you still feel overstimulated, irritable, or experience headaches, switch to Multivitamin One MF. This uses non-methylated forms of folate and B12 which are better tolerated by those sensitive to methylated nutrients.

Is this product right for me?

Multivitamin One was formulated for people who want more from their multivitamin without taking more pills. Here are 15 scenarios where Multivitamin One may help, each supported by published research:

1. The MTHFR Variant Carrier Who Isn’t Converting Folic Acid

Situation You’ve been taking a standard multivitamin with folic acid for years, yet you still experience low energy, brain fog, or uneven mood. Your body may not be converting folic acid into its usable form due to a common MTHFR gene variant that affects up to 40% of the population.

Support: Multivitamin One delivers folate as Quatrefolic® (6S)-5-methyltetrahydrofolate, bypassing the MTHFR conversion step entirely so your body can use it optimally, regardless of your genetic makeup.†

Research: MTHFR polymorphism (C677T) reduces enzyme activity by 35% in heterozygotes and 70% in homozygotes, impairing folate metabolism and raising homocysteine. Supplementation with 5-MTHF bypasses this impairment entirely. [1, 2]

2. The Busy Professional Running on Caffeine Instead of Nutrients

Situation: You rely on coffee to get through the day but crash by 2 PM. Your energy feels borrowed, not built. Low B vitamin intake, especially B12, is a common contributor to persistent low energy that caffeine can’t fix.

Support: Multivitamin One provides dual active B12 (methylcobalamin + adenosylcobalamin) plus a full spectrum of active B vitamins that support cellular energy production directly, without needing multiple conversion steps.†

Research: Vitamin B12 is essential for facilitating energy, lipid, and carbohydrate metabolism. B12 insufficiency results in elevated homocysteine and methylmalonic acid, both markers of impaired energy metabolism. Active cobalamin forms (methyl and adenosyl) are immediately usable without conversion. [3, 4]†

3. The Screen-Fatigued Worker Whose Eyes Need Support

Situation: You spend 8+ hours a day on screens and notice increasing eye strain, dryness, and difficulty focusing. Extended screen time and blue light exposure increase the demand on your eyes over time.

Support: Multivitamin One includes lutein, a carotenoid that concentrates in the macula and filters blue light while supporting healthy oxidative stress levels in the eye.†

Research: A 2025 RCT in Frontiers in Nutrition found that 6 months of lutein/zeaxanthin supplementation in adults with 6+ hours daily screen time supported visual sharpness, comfort measures, and normal macular recovery. Lutein filters blue light and supports healthy oxidative stress levels in photoreceptor cells. [5, 6]†

4. The Frequent Traveler Who Desires Immune Support

Situation: Travel disrupts your routine: sleep, nutrition, and stress all shift, putting extra demand on your immune defenses precisely when you need them most.

Support: Take Multivitamin One before and during travel. Its combination of vitamin D, zinc, selenium, and vitamin A provides broad-spectrum immune system support.†

Research: A 2017 systematic review of 25 RCTs (11,321 participants) found vitamin D supplementation supported healthy respiratory tract function, particularly with daily/weekly dosing. Zinc supports healthy antiviral and antibacterial immune responses, while selenium supports NK cell and T lymphocyte function. [7, 8, 9]†

5. The Aging Adult Who Wants to Stay Mentally Sharp

Situation: You want to keep your mind sharp and your memory strong as you age. You’ve noticed it takes a bit longer to recall names or stay focused during conversations.

Support Multivitamin One supports cognitive health through methylfolate (which plays a role in neurotransmitter production), active B12 (which supports healthy myelin), and lutein (the dominant carotenoid in brain tissue).†

Research: A 4-month double-blind trial in older women found lutein supplementation (12 mg/d) supported verbal fluency scores. Separately, L-methylfolate has been studied for its role in supporting healthy neurotransmitter production. Lutein accounts for 66–77% of total carotenoid concentration in human brain tissue. [10, 11, 12]†

6. The Person Who Wants to Support Healthy Homocysteine Levels

Situation: Your doctor has flagged elevated homocysteine on your bloodwork. Supporting healthy homocysteine metabolism requires adequate B vitamins in forms your body can actually use—and standard folic acid may not be getting the job done.†

Support: Multivitamin One provides the trio of nutrients that support healthy homocysteine metabolism: active folate (methylfolate + folinic acid), active B12 (methylcobalamin + adenosylcobalamin), and vitamin B6—all in their bioavailable forms.†

Research: Folate, B12, and B6 work together to support healthy homocysteine metabolism. Active methylfolate directly supports the remethylation of homocysteine to methionine. Adequate intake of these B vitamins in bioavailable forms supports normal homocysteine levels already within the healthy range. [13, 14]†

7. The High-Intensity Athlete Under Oxidative Stress

Situation You train hard and recover slowly. Intense exercise generates large amounts of free radicals that challenge your body’s antioxidant defenses, leading to prolonged soreness and fatigue.

Support Multivitamin One includes glutathione (Emothion®), superoxide dismutase (Extramel®), and mixed tocopherols: a triple antioxidant support layer to maintain your body’s healthy response to exercise-induced oxidative stress.†

Research: Plant-derived SOD supplementation (500 mg/day for 6 weeks) significantly increased SOD activity and supported healthy C-reactive protein levels in trained athletes. Glutathione supplementation (500–1000 mg/d) elevated body stores by 30–35% and supported NK cell function and lymphocyte proliferation. [15, 16]†

8. The Vegetarian Who Wants Complete B12 and Mineral Support

Situation: You eat a plant-rich diet but know that B12, zinc, and other nutrients found primarily in animal foods may be lower in your diet. Anti-nutrients like phytates and oxalates in plant foods can further reduce mineral absorption.

Support: Multivitamin One uses Albion® chelated minerals that are protected from binding by anti-nutrients, plus active B12 forms that don’t require animal-sourced cofactors. The vegetarian capsule is fully plant-compatible.†

Research: Albion® mineral amino acid chelates are protected from anti-nutrient binding. Zinc bisglycinate chelate demonstrated 43% greater absorption than zinc gluconate. Those following plant-based diets have increased demand for supplemental B12, which supports DNA synthesis and cellular energy production. [17, 18]†

9. The Parent Who Wants One Simple Supplement for the Whole Family

Situation: You’re juggling multiple supplement bottles for different family members. You want something clean that works for adults and teenagers.

Support: Multivitamin One is suitable for ages 4 and up and bariatric patients. Capsules can be opened and contents emptied into food or drink for children.

Research: Active folate (5-MTHF) is important during pregnancy. In a case series of 33 couples with MTHFR variants and fertility concerns, supplementation with 800 μg/day of Quatrefolic® supported successful pregnancy outcomes in 30 of 33 couples. Active folate bypasses the MTHFR conversion step entirely. [19]†

10. The Stressed-Out Person Burning Through B Vitamins

Situation: Frequentstress increases your body’s demand for B vitamins—particularly pantothenic acid (B5), which is essential for producing stress hormones via the adrenal glands. The more stress you’re under, the faster you may burn through your B vitamin reserves.†

Support: Multivitamin One delivers a generous 50 mg of pantothenic acid (B5) alongside the full spectrum of active B vitamins to support your body’s stress response and energy production during demanding periods.†

Research: Your adrenal glands need pantothenic acid (B5) to produce CoA which is the enzyme required to make stress-response hormones like cortisol. When stress is frequent, demand goes up. A 2019 meta-analysis of 16 randomized controlled trials (2,015 participants) found that B vitamin supplementation significantly supported healthy stress levels, with the strongest benefits in those under the most pressure. [20, 21]†

11. The Supplement Minimalist Who Hates Taking Multiple Pills

Situation: You know you should take a multivitamin, but you can’t stand regimens that require 4–8 capsules daily. Most comprehensive multivitamins require multiple servings to deliver meaningful amounts.

Support: Multivitamin One is exactly what it sounds like: one capsule. It delivers methylated B vitamins, chelated minerals, and antioxidants in a single capsule designed for those who value simplicity without sacrificing quality.†

Research: The active, pre-converted forms of nutrients used in this formula (5-MTHF, methylcobalamin, adenosylcobalamin, chelated minerals) are more efficiently utilized per milligram than their synthetic counterparts, supporting effective nutrient delivery in fewer capsules. Quatrefolic® delivers finished folate that requires no enzymatic conversion. [1, 2]†

12. The Person With a Sensitive Stomach Who Can’t Tolerate Most Vitamins

Situation: Every multivitamin you’ve tried causes nausea, stomach or digestive discomfort. Cheap mineral forms like ferrous sulfate and magnesium oxide are notorious for being hard on the stomach.

Support: Multivitamin One uses Albion® chelated minerals (bound to glycine amino acids) that are gentle on the digestive system. No iron or magnesium is included to avoid common GI irritants, giving you the option to customize those separately.†

Research: Albion® chelated minerals offer enhanced bioavailability and high tolerability. The chelation process mimics the body’s natural digestive process, producing readily absorbable minerals that are gentle on the stomach. Backed by 160+ studies and 70+ human clinical trials. [17, 22]†

13. The Person Who Wants Mood and Motivation Support

Situation: You feel flat or unmotivated and want nutritional support for a healthier mood. You’ve tried various approaches but haven’t considered that your neurotransmitter production may need better methylation support.

Support: Methylfolate plays a role in the production of serotonin, dopamine, and norepinephrine. Multivitamin One’s methylfolate + active B12 combination supports the methylation cycle involved in healthy neurotransmitter production.†

Research: L-methylfolate plays a role in neurotransmitter synthesis and has been studied as adjunctive nutritional support for healthy mood. MTHFR polymorphisms can affect folate availability for these pathways. Active folate bypasses these genetic variations to support methylation directly. [11, 23]†

14. The Older Adult With Changing Nutrient Absorption

Situation: As you age, your stomach acid production naturally declines, making it harder to extract B12 from food and absorb minerals efficiently. You may be eating well yet still not getting optimal levels of key nutrients.

Support: Multivitamin One uses pre-activated nutrients that don’t depend on strong stomach acid for absorption. Chelated minerals, active B12, and methylfolate are designed to be absorbed efficiently regardless of digestive changes.†

Research: B12 absorption from food decreases with age due to declining stomach acid and intrinsic factor production. Supplemental forms of B12 bypass this limitation. Chelated minerals similarly resist pH-dependent solubility issues, maintaining absorption even in low-acid environments. [17, 24]†

15. The Clean Label Seeker Who Reads Every Ingredient

Situation: You reject supplements with synthetic fillers, artificial colors, and cheap nutrient forms. You’ve learned that folic acid and cyanocobalamin aren’t the same as what your body actually uses—and you want better.

Support: Multivitamin One contains zero folic acid, zero cyanocobalamin, no artificial colors, no GMOs, and uses premium branded ingredients (Quatrefolic®, MecobalActive®, Albion®, Emothion®, Extramel®) you can verify independently.†

Research: Unconverted folic acid may accumulate in circulation when intake exceeds the body’s conversion capacity. Up to 40% of the population carries MTHFR variants that further limit this conversion. Active folate forms bypass this concern entirely.

Key Ingredients

True Folate (Quatrefolic®)

Features folate (vitamin B9) in its bioavailable, active forms of methylfolate and folinic acid (methyl-free form), supporting mood and cognition, fetal development, proper genetic expression and DNA/RNA synthesis. L-methylfolate supports healthy methylation while folinic acid supports healthy blood cells, platelets, skin and neurotransmitters.†

Bioavailable B12 (MecobalActive®)

‘Adeno’ and ‘Methyl’ are known as superior forms of vitamin B12 that your body can readily utilize, acting as coenzymes to power important enzymes. Bioactive B12 supports healthy energy production, detoxification and is required to utilize folate for methylation processes.†

Vitamin A

Provides the bioavailable form, as retinyl palmitate, to support common BC01 gene variations for optimal eye, mucus membrane, and immune system health. It plays significant roles in respiratory and lung health, normal inflammatory signaling and healthy immune system defenses.†

Superoxide Dismutase (SOD)(Extramel®)

Superoxide Dismutase (SOD) Contains plant-derived superoxide dismutase with activity similar to SOD1 and SOD2, supporting the body’s natural antioxidant defense systems.†

Lutein

Supports healthy levels levels of oxidative stress in the macula and lens of the eye.
