D3 + K2

We're a new brand, and we know trust is earned. That's why every batch is third-party tested, we publish exact ingredient doses (no proprietary blends), and we offer a full 30-day money-back guarantee. We'd rather let the product speak for itself.

Fathom was built for people who live deliberately. People who train with intention and view discipline not as punishment but as freedom. Fathom is more than a brand. It is a signal. A marker of a mindset. A commitment to never negotiate with your own potential.

Applicable Fathom Nutrition products are tested and certified by 3rd party labs to verify they do no contain unsafe levels of contaminants, prohibited substances, or masking agents, and that what is on the label matches what is in the product. Consumers can feel safe knowing that Fathom Nutrition products have been tested to the highest standards, at a GMP-certified facility, and audited regularly.

Fathom Vitamin D3 + K2 pairs two essential, fat-soluble vitamins that work synergistically to support bone health, immune function, and cardiovascular wellness. Vitamin D3 helps the body absorb calcium, while Vitamin K2 (as MK-7) supports proper calcium utilization.

This product is formulated for individuals seeking a daily foundation of support for long-term health, especially those with limited sun exposure or diets low in these nutrients. Vitamin D3 and K2 are two of the most important, but often under-consumed, nutrients for long-term health.†

• Supports Calcium Absorption and Bone Health. Vitamin D3 helps the body absorb calcium, while K2 directs calcium to the bones where it’s needed. †
• Supports Cardiovascular Health. Vitamin K2 (MK-7) supports normal calcium transport in the body, helping maintain vascular integrity. † 
• Supports Immune System Function. Vitamin D plays a role in supporting the immune system, particularly in individuals with low sun exposure. †
• Helps Maintain Nutrient Balance. Combining D3 and K2 helps maintain a healthy ratio of calcium metabolism, especially in active adults and aging populations. †

Take one serving daily, with a meal or as directed by a health professional.
