Look for at least 5,000 IU of Vitamin D3 and 100 mcg of Vitamin K2 for proper absorption and synergy.
Not all K2 is equal. MK-7 is the most bioavailable, longest-lasting form. Don’t settle for MK-4 or unlisted types.
Brands that offer a 90-day guarantee show confidence in their product. It gives you time to try the supplement and feel the difference (risk free).
It should be easy to return a product if it doesn’t work for you. Avoid brands with unclear or restrictive return policies—look for those that make the process simple and honest.
Products that don’t list whether their K2 is MK-7 are often low quality or ineffective.
Some brands offer just 1,000 IU of D3 or fail to include enough K2 to make a difference. It’s a combo product—both need to be effective.
If there’s no money-back guarantee, think twice. Reliable brands make it easy to return a product if it doesn’t work for you.
Cheaper products often mean weak doses, fillers, or poor sourcing. For something you take daily, it’s worth paying for quality.
Made in the USA in an FDA-regulated facility. Luma Nutrition adheres to Good Manufacturing Practices (GMPs).
