OUR STORY

Only Multivitamin, the ultimate destination for those seeking a medical-grade, vegan, and proprietary approach to total wellness. We believe that the right combination of methylated vitamins, plant-based vitamins, and scientifically proven formulations can transform how you feel every day. That’s why we’ve dedicated ourselves to creating supplements designed to address the varied needs of your body, including those related to MTHFR gene concerns, gene mutations, and daily energy demands. Our focus on high-absorption, organic ingredients ensures your body receives the essential nutrients it needs in their most bioavailable forms.

At Only Multivitamin, our flagship product is METHL—a comprehensive supplement developed to harness the power of methylated vitamins and plant-based ingredients. By combining cutting-edge nutritional science with a deep respect for nature’s bounty, we have crafted a solution that supports numerous health goals. METHL addresses MTHFR gene challenges, helps boost energy, and supports overall vitality with its B-complex synergy and organic botanical extracts. Our team of experts is committed to providing a supplement that is clinically tested, cruelty-free, and respectful of both the body and the environment.

The Story Behind Only Multivitamin

Before launching Only Multivitamin, we noticed a gap in the market for truly comprehensive, medical-grade supplements that cater to individuals with specific genetic and nutritional needs. Many off-the-shelf products simply don’t factor in issues like MTHFR gene mutations, nor do they offer methylated vitamins in forms that the body can fully use. Even more, many supplements on the market aren’t vegan, use synthetic fillers, and lack clear evidence of being scientifically proven to deliver the promised results. We set out to change that paradigm. By partnering with nutritionists, geneticists, and herbalists, we developed METHL, a product that stands out from the crowd.

Why Methylated Vitamins?

Methylated vitamins are crucial for individuals who may have a hard time converting standard vitamins into their active forms. The MTHFR gene plays a key role in this process, helping convert folate into methylfolate—a form the body can readily use. When there are MTHFR gene variations, the body’s ability to perform this conversion can be compromised, leading to issues such as low energy, poor detoxification, and suboptimal health. By offering methylated vitamins—like methylfolate (5-MTHF) and methylcobalamin—we ensure that your body can absorb and use these nutrients more efficiently. This means you’re not just taking vitamins; you’re getting vitamins in a form that genuinely supports your well-being.

Plant-Based and Organic Ingredients

In addition to methylated vitamins, METHL features a wide array of plant-based vitamins and organic botanical extracts. We’ve sourced our ingredients from farms and suppliers who prioritize sustainability, quality, and ethical practices. Our dedication to organic standards helps ensure that each dose of METHL is free from harmful pesticides, synthetic fertilizers, and other toxic chemicals. Plus, the vegan nature of our supplement aligns with our mission to minimize harm to animals and the environment. We believe that good health shouldn’t come at the expense of our planet, and with METHL, it doesn’t have to.

Scientifically Proven Formulations

Our entire range at Only Multivitamin—from METHL to other specialized supplements—is anchored in scientific research. Each ingredient is included based on clinically tested evidence that supports its efficacy. We don’t simply rely on trendy ingredients or buzzwords; instead, we carefully vet each vitamin, mineral, and plant extract for its ability to deliver tangible results. From B-complex synergy that boosts your energy levels to specialized nutrients that address gene mutation concerns, we formulate every product to meet real health needs. Our commitment to scientifically proven methods ensures you can trust the quality and effectiveness of everything we offer.

High Absorption and Bioavailability

One of the key factors that sets METHL apart is its focus on high absorption and bioavailability. It’s not enough to consume nutrients if your body can’t fully utilize them. That’s why we utilize methylated forms of B vitamins and carefully selected plant-based extracts known for their superior absorption profiles. By using forms like methylcobalamin and methylfolate, we ensure that those with compromised methylation pathways—due to MTHFR gene variations—can still achieve optimal nutrient uptake. Our proprietary blends are designed with synergistic co-factors to enhance absorption further, allowing your body to benefit from every single ingredient.

Addressing MTHFR Gene Concerns

That’s why we utilize methylated forms of B vitamins and carefully selected plant-based extracts known for their superior absorption profiles.

Our proprietary blends are designed with synergistic co-factors to enhance absorption further, allowing your body to benefit from every single ingredient.

Proprietary Blends for Enhanced Efficacy

Our team of expert formulators has developed proprietary blends to maximize the benefits of each ingredient in METHL. These blends contain not just methylated vitamins and plant-based vitamins, but also carefully chosen herbal extracts that work in harmony with essential nutrients. Certain herbs can support detoxification, while others may promote better digestion or stress management. By integrating these botanical extracts with our high-quality vitamins and minerals, we offer a comprehensive approach that addresses multiple areas of health simultaneously. This synergy allows our products to deliver lasting, noticeable benefits, moving beyond the basics of standard multivitamins.

Medical-Grade Quality

When we say medical-grade, we mean it. Every step in the creation of METHL—from ingredient sourcing to final packaging—adheres to strict quality control standards. We work with facilities that follow Good Manufacturing Practices (GMP) and conduct third-party lab testing to verify purity, potency, and safety. This level of medical-grade oversight ensures you receive a supplement that not only meets but exceeds industry benchmarks. Our goal is to give you total confidence in the products you take, knowing they have undergone rigorous scrutiny.

Vegan and Cruelty-Free Commitment

At Only Multivitamin, ethical considerations are just as important as scientific ones. That’s why all our products—including METHL—are vegan and cruelty-free. We believe in the principle of doing no harm, extending that philosophy to animals and the environment as well as our customers. By utilizing plant-based and organic ingredients, we reinforce our mission to protect ecological balance while delivering unparalleled nutritional support. This approach resonates with the growing number of consumers who see wellness as encompassing not just personal health, but the health of our planet too.

Clean-Label Transparency

We prioritize transparency in all that we do, ensuring our customers know exactly what they’re putting into their bodies. Our clean-label commitment means you won’t find hidden fillers, artificial colors, or questionable additives in METHL. Instead, our labels clearly list every ingredient, along with details on its source and purpose. We want you to understand how and why each component is included. This level of honesty sets us apart from many supplement brands that obscure crucial details behind proprietary blends or complicated jargon.

Holistic Approach to Wellness

While METHL may be our flagship offering at Only Multivitamin, our broader vision centers on a holistic approach to health. We recognize that supplements are just one facet of a well-rounded lifestyle, which is why we also provide educational resources and support on topics such as nutrition, exercise, and stress management. When you choose METHL or any of our other products, you’re not just buying a supplement—you’re joining a community of health enthusiasts and professionals who value evidence-based solutions and ethical practices.

Our journey with Only Multivitamin is far from over. We continually invest in research to stay at the forefront of nutritional science, exploring new ways to enhance the bioavailability and effectiveness of our methylated and plant-based formulas. From investigating novel herbal extracts to refining our proprietary blends, we never stop pushing the boundaries of what’s possible. In the coming years, we plan to expand our product line to include specialized formulas for different life stages, targeted organ support, and more. Through it all, we remain committed to delivering medical-grade, vegan, organic, and scientifically proven supplements under the Only Multivitamin umbrella.mall Call to Action Headline
