Protect+5 — Comprehensive Fat-Soluble Vitamin and Nutrient Absorption Support

Balanced Protection for Bone, Heart, and Immune Health

Protect+ is a next-generation formula designed to support the optimal balance, absorption, and biological activity of key fat-soluble vitamins essential for long-term health.
Combining clinically validated, bioavailable forms of Vitamins K2 (MK-7), D3, A, and E with AstraGin®, Protect+ helps promote bone strength, cardiovascular wellness, immune balance, and antioxidant protection— while ensuring maximum nutrient utilization.

Featured Benefits

  • Supports healthy calcium utilization for bones, teeth, and cardiovascular integrity*

  • Promotes balanced immune and cellular function*

  • Provides broad-spectrum antioxidant defense*

  • Encourages optimal absorption and bioavailability of fat-soluble vitamins*

  • Supports healthy aging and metabolic vitality*

Vitamin K2 (MK-7 as K2VITAL® Delta) — 300 mcg

Vitamin K2 (MK-7) activates key proteins involved in calcium metabolism, helping direct calcium to bones and away from soft tissues.*
Protect+ features K2VITAL® Delta, a double micro-encapsulated, >99% all-trans bioactive form of MK-7 for superior stability, bioavailability, and potency.
Among all K-vitamins, MK-7 offers the longest half-life and best tissue distribution, supporting skeletal strength, vascular flexibility, and cellular energy pathways.

Vitamin D3 — 125 mcg (5,000 IU)

Vitamin D3 is essential for calcium absorption, bone integrity, immune function, and cellular resilience. It supports healthy gene expression and cellular signaling pathways associated with longevity, metabolic efficiency, and a balanced inflammatory response.

Vitamin A 

Vitamin A (retinol) plays a central role in cell differentiation, tissue renewal, immune function, and visual health. It also contributes to skin integrity and mucosal barrier function and acts as an antioxidant nutrient that helps maintain cellular health during oxidative stress.

Vitamin E 

Vitamin E is a potent lipid-soluble antioxidant that protects cell membranes from oxidative damage and helps maintain red blood cell integrity.
It also supports the stability of other fat-soluble nutrients, including vitamins A and C, enhancing their biological efficacy.

AstraGin® — Bioavailability Optimizer

Derived from Panax notoginseng and Astragalus membranaceus, AstraGin® has been shown in over a dozen in-vitro studies to support nutrient absorption and cellular uptake.
It promotes improved transport of vitamins, amino acids, and peptides through intestinal pathways, optimizing bioavailability and nutrient efficiency.
