Vitamin D Plus K
Vitamin D does half the job. Vitamin K does the other half.
Vitamin D Plus K is a professional-quality daily capsule that pairs bioavailable vitamin D3 with vitamin K — two nutrients that support different, complementary stages of the body’s normal calcium metabolism. Together they help support healthy bones, immune health and normal muscle function in one simple once-daily habit.*
Two nutrients, one shared process.
Calcium metabolism isn’t a single event — it’s a sequence. Vitamin D helps support the body’s normal absorption of calcium from food, and vitamin K helps support how that calcium is utilized once it’s there. That’s why a D3 + K2 supplement has become a standard pairing in professional-quality bone health nutrition rather than a niche combination.*
Vitamin D Opens The Door
Vitamin D3 helps support the body's normal absorption of calcium from the food you eat — the first step in healthy calcium metabolism.*
Vitamin K Directs Traffic
Vitamin K helps support the normal utilization of calcium within the body, contributing to healthy bones and normal soft-tissue function.*
Better Together
Because the two nutrients work on different parts of the same process, they are commonly paired in professional-quality formulations.*
Everyday Immune Support
Vitamin D is one of the most widely studied nutrients for supporting normal, healthy immune function throughout the year.*
Muscle Function
Vitamin D also contributes to the maintenance of normal muscle function — part of staying strong and active as you age.*
Consistency Over Intensity
Vitamin status reflects habits, not single doses. Steady daily intake alongside good nutrition is what supports healthy levels over time.
A foundational daily vitamin, formulated properly.
Bioavailable forms, a sensible pairing and a single convenient capsule — designed to make daily bone, immune and calcium support genuinely easy to keep up with.
Bone Health Support*
Formulated to support healthy bones by pairing the two nutrients most closely tied to normal calcium metabolism.
Normal Calcium Metabolism*
D3 supports calcium absorption while K supports the body's normal utilization of that calcium.
Immune Health Support*
Daily vitamin D helps support healthy immune function — especially valuable through low-sunlight seasons.
Muscle Function Support*
Contributes to the maintenance of normal muscle function as part of an active, healthy lifestyle.
Highly Bioavailable Forms
Cholecalciferol (D3) and vitamin K in readily usable forms, chosen for absorption rather than label appeal.
Convenient Once-Daily Capsule
One small capsule per day. 60 capsules per bottle — no powders, no measuring, no routine to rebuild.
Professional-Quality Formulation
A practitioner-grade supplement curated by Dr. Tammy for the Hormone Bliss wellness lineup.
Easy To Add To Your Routine
Pairs naturally with the supplements and hormone wellness protocol you may already be following.
An ingredient list with nothing to hide.
A closer look at the vitamin D3, vitamin K2 and supporting components that make up this daily bone and immune support formula.
Vitamin D3 (Cholecalciferol)
The same form of vitamin D your skin produces in sunlight, and the form most efficiently used by the body. Supports healthy calcium absorption, bone health, immune function and normal muscle function.*
Vitamin K2 (Menaquinone, MK-7)
A long-acting form of vitamin K that supports the normal activity of the proteins involved in how the body uses calcium — helping support healthy bones and normal soft-tissue function.*
Vitamin K1 Family Support
Vitamin K is a family of fat-soluble nutrients naturally found in leafy greens and fermented foods. Supplementing helps support consistent daily intake when diet alone varies.*
Lipid-Friendly Delivery Base
Both vitamin D and vitamin K are fat-soluble, so the formula is designed to be taken with a meal containing some fat for optimal absorption.*
Clean Capsule Formulation
A straightforward capsule built around the active nutrients — no proprietary mystery blends and no unnecessary fillers.
Professional-Grade Sourcing
Ingredients selected for purity, potency and bioavailability, consistent with the standards used across every Hormone Bliss supplement.
A foundational nutrient for a body that keeps going.
Vitamin D is unusual among nutrients: your skin makes it from sunlight. That sounds simple until you account for winter, latitude, sunscreen, indoor work and the fact that most modern days are spent under a roof. Nutrition helps — fatty fish, egg yolks, fortified foods — but daily intake often varies more than people expect.
Supporting healthy vitamin D levels is one of the simplest, most consistent things you can do for bone health, muscle function, immune health and everyday wellness. Adding vitamin K alongside it supports the second half of the same story — how the body uses the calcium vitamin D helps it absorb.*
Bone health becomes especially worth attention through perimenopause and menopause, when shifting hormones change what the body needs. Many women pair foundational nutrition with bioidentical hormone therapy and at-home hormone testing.
Bone Health
Bone is living tissue that remodels continuously. Healthy vitamin D and vitamin K intake supports the normal calcium metabolism that process depends on.*
Muscle Function
Vitamin D contributes to the maintenance of normal muscle function — foundational for strength, balance and staying active.*
Immune Support
Vitamin D is one of the most studied nutrients for supporting normal, healthy immune function year-round.*
Healthy Aging
Maintaining healthy nutrient status is one of the simplest, most consistent things you can do to support wellness over the decades.
Sunlight & Season
Skin makes vitamin D from sunlight, but latitude, season, sunscreen, time indoors and skin tone all influence how much you produce.
Nutrition's Role
Fatty fish, egg yolks, leafy greens and fermented foods contribute, though many adults find daily intake varies more than they expect.
Hormone Wellness
Bone density support becomes especially relevant through perimenopause and menopause, when hormone shifts change what the body needs.
Daily Consistency
Vitamin status builds gradually. A daily habit supports steadier nutrition than occasional high-dose catch-up.
One capsule. One easy daily habit.
Vitamin D Plus K is designed to slot into the routine you already have. No powders, no measuring — just a single daily capsule taken with a meal.
