    D3+K2 and Creatine

    I have used other D3+K2 products before. I like that Gains also has Vitamin a in its formula.

    Love the Creatine better than any others I have used before.

    Thanks for a great product

    Great Product

    I have only been taking the D3 + K2 for a week, but so far it’s going great! I like the fact that they are easy to swallow gel capsules…. NOT horse pills!

MAKING GAINS
TOGETHER

We’re more than a brand. We’re part of the community. Founded by Braven, Marley, and Douglas Grant with over 55 years of combined experience in bodybuilding and sports.

Our formulator has worked with NBA teams, Olympians, and elite athletes. Gains was built to create the game-changing products we couldn’t find, made for those committed to winning.

OUR STORY

Everything You Need to Know

Why combine Vitamin D3 and K2?

These two vitamins work together. D3 increases calcium absorption while K2 ensures calcium is directed to bones, not arteries, supporting strength, mobility, and long term cardiovascular health.

What makes this formula better than standard D3 supplements?

It uses algae sourced D3, premium MK 7 K2, and Vitamin A for comprehensive immune and performance support. The algae oil base boosts absorption naturally.

How soon will I feel the benefits?

Many people notice improvements in energy, mood, and recovery within the first few weeks. Structural benefits like bone and joint support continue building over months of consistent use.

Can I take this daily?

Yes and you should. It is designed for daily use and provides optimal benefits when taken consistently.

Can this help performance and training?

Absolutely. Vitamin D3 supports muscle strength, immunity, and hormone function, while K2 helps maintain joint and bone integrity. This leads to better movement, endurance, and recovery.

Is this safe to pair with other Gains supplements?

Yes. It stacks perfectly with Square One for foundational nutrition, Omegas for inflammation support, and Total Digest for improved absorption.
