Vitamin D3 10,000 IU with K1 K2 & GG - High Absorption

Our review of this high-potency vitamin D supplement finds it best suited for adults seeking a clinically relevant daily dose of vitamin D3 with supportive cofactors. The single biggest reason to consider it is the 10,000 IU dose paired with vitamins K1 and K2 (as MK-4) and geranylgeraniol, which together aim to support bone and immune health while addressing absorption concerns. For someone monitoring levels or under practitioner guidance, this formula offers a concentrated, practitioner-grade option in a softgel designed for improved bioavailability.

Key Features

• High potency D3: A clinically relevant 10,000 IU (250 mcg) dose of vitamin D3 per serving supports people with low levels or higher therapeutic needs.
• Vitamins K1 and K2: Includes both K1 and MK-4 K2 to support calcium partitioning and complementary cardiovascular and bone health benefits.
• Geranylgeraniol (GG): GG is included to support immune and cellular pathways that work together with vitamins D and K.
• Improved absorption technology: Evail formulation uses quillaja extract plus MCT to enhance the softgel's nutrient bioavailability compared with plain oil capsules.
• Clean formulation: Made without GMOs, gluten, dairy, or soy, which suits users looking for a minimal-ingredient practitioner-grade product.
• Practitioner trusted: Produced by a brand commonly recommended by functional medicine professionals, which may appeal to those seeking clinical-grade supplements.

Who It's For

This supplement is a strong fit for adults who have low vitamin D levels, those following practitioner guidance for higher-dose vitamin D therapy, or people wanting a combined D and K formula to support bone and cardiovascular health. The high potency makes it particularly useful for seasonal deficiency correction or therapeutic short-term use.

It is not intended for routine low-dose maintenance for everyone; people who only need a modest daily amount should look for lower-potency options. Anyone pregnant, breastfeeding, or taking blood-thinning medication should consult a healthcare provider before using a high-dose D plus K product.
