BENEFITS 

Vitamin D3 and K2 are both essential fat soluble nutrients that supply many benefits individually, but they rely on each other to function optimally. EnDuro D takes advantage of these synergistic effects to provide a superior formula in an easily absorbable softgel. For immune system support, bone health, and cardiovascular health, take EnDuro D: the dynamic duo for health and well-being.

HOW TO USE 

Maintenance dosage
Take 1 softgel daily with meals or separately.

Acute needs (winter months, low sunlight conditions)
Take 2–3 softgels daily

MASSIVE BENEFITS FROM THE D3/K2 COMBINATION 

BY STEVE BORN

The word synergy “refers to when an interaction of elements produces an effect that is greater than the effect that would have resulted from simply adding up the effects of each individual element. In other words, it is what happens when a combination of things produces an effect or result that is said to be ‘greater than the sum of its parts.”

Vitamins D3 and K2—both essential, fat-soluble nutrients— are a perfect example of synergy. While each of these extraordinarily beneficial vitamins supply many individual benefits, they rely on each other to function optimally, especially in regards to bone and arterial health.

The researched benefits of vitamin D3 are so plentiful that it would take every page of all 126 issues of Endurance News (and most likely many more than that) to discuss them all (do a Google search on “vitamin D benefits” and you’ll probably be online for a month or so). In fact, there is no other nutrient that I know of—with the exception of magnesium—that is involved in more aspects of human health than vitamin D3.

The benefits from vitamin D3 supplementation are to support the immune system proper utilization of calcium to optimize bone density and overall bone health normalize blood pressure and support cardiovascular health and so much more.

Vitamin K2 works with vitamin D3 for supporting both bone and cardiovascular health by activating a protein called osteocalcin, which helps keep calcium out of the arteries while increasing the amount of calcium in the bones (teeth as well). Vitamin K2, working alongside vitamin D3, also promotes healthy glucose metabolism to maintain proper blood sugar levels thus helping protect against type 2 diabetes.

While these are the primary benefits of vitamins D3 and K2, there are many other benefits, far too many to list here. Everyone* will benefit from supplementation of vitamin D3 and vitamin K2, the dynamic duo for numerous areas of human health.

ENDURO-D SOFTGEL CONTENTS

Vitamin D3................. 50 mcg (2,000IU)

Vitamin K2...........................1,680 mcg
Menaquinone 4 (MK-4).....1500 mcg
Menaquinone 7 (MK-7).......180 mcg

TWO MAIN FORMS OF VITAMIN D

D2 (ergocalciferol)
The plant-derived form.

D3 (cholecalciferol)
The sun-derived form, animal-derived (lanolin) form, and the form that is believed to effectively raise bodily levels of active vitamin D better than D2.

NOTE: In 1919, German researcher Adolf Windaus discovered three forms of vitamin D: D1, D2, and D3. When it was found that D1 was actually a mixture of compounds instead of a pure vitamin D product, the term D1 was dropped.

TWO MAIN FORMS OF VITAMIN K

K1 (phylloquinone)
The plant-derived form, and the main form of vitamin K in the diet. Vitamin K1 is poorly absorbed, with less than 10% absorption rates.

K2 (Menaquinone)
The often found in foods that contain fat and suggested to be a better-absorbed form than K1 that also circulates in the blood longer than K1.

NOTE: Vitamin K2 has a number of menaquinone (MK for short) subtypes, with the most beneficial ones being MK-4, and MK-7. Research on the MK-4 subtype of vitamin K2 used 1500 mcg/day.

Studies on MK-7 used 180 mcg/ day. Also, Dr. Dennis Goodman, author of Vitamin K2: The Missing Nutrient for Heart and Bone Health, suggests amounts between 150 to 180 mcg/day of MK-7. These are the amounts found in EnDuro D.

BENEFITS 

Race Day Boost greatly enhances the performance of your body’s three energy production pathways. That means, no matter what your race pace may be—low-to-moderate intensity, higher intensity/ anaerobic, or flat-out sprint—a four-day load with Race Day Boost delivers the goods to help you meet or exceed your race day expectations. Race Day Boost superbly buffers lactic acid and dramatically improves oxygen utilization, which is why it’s no surprise that, in the most extensive research to date on Race Day Boost’s primary ingredient, study subjects enjoyed a whopping 8% improvement in performance time.

HOW TO USE 

Use for major events.

One-Day Event—"A" Race
Take 4 capsules with food and water 4 times per day (16 capsules daily) for 4 days before a competition.

Multi-Day Event
Follow loading protocol for 3 days prior to start:

4 capsules, 4 times per day.

Then follow this twice-daily “maintenance dose” protocol after each stage:

Take 4 capsules with Recoverite® as soon as possible after racing each day, as well as another 4-capsule dose with food later in the day/evening.

PRO TIP

Do not use it for every race because this product has a “tolerance factor.” Therefore, use it ideally only four to six times per year.

INGREDIENT BREAKDOWN 

Sodium (Tribasic) Phosphate – This compound enhances the functioning of all three of the body’s ATP-producing energy systems: the short-term ATP-CP system, the medium-term lactic acid system, and the long-term oxygen/aerobic system.

A primary benefit of sodium (tribasic) phosphate is its ability to buffer blood acidity and help maintain a more ideal acid-alkaline balance by neutralizing excess hydrogen ions within the muscle cell. Effectively buffering lactic acid extends energy production within this system. This nutrient also increases 2,3-diphosphoglycerate (2,3-DPG). This compound, found in red blood cells, helps release oxygen from hemoglobin into the muscle cells. An increase in 2,3-DPG will improve the availability of oxygen to working muscles during exercise.

Malic Acid – A natural substance found in apples and other fruits. Malic acid helps balance the extreme alkalinity of Race Day Boost, thus minimizing-to-eliminating the potential for stomach distress. As an essential component of the Krebs cycle, malic acid also helps boost energy levels and is beneficial for liver health.
