D Synergy - The Best Vitamin D Supplement

This is the most comprehensive Vitamin D supplement on the market! Our D Synergy  provides 4,000 IUs of vitamin D (a clinically relevant dose for optimal utilization in the body.) This product also contains clinically relevant dosages of:

• Vitamins A
• Vitamin K
• Vitamin E isomers
• Boron
• Magnesium

What Are The Benefits Of Taking Magnesium & Vitamin D Together?

Magnesium is essential in the metabolism of vitamin D, and taking large doses of vitamin D without also taking a magnesium supplement can actually cause severe depletion of magnesium. Adequate magnesium supplementation should be considered as an important aspect of vitamin D therapy. It is estimated that nearly half of the population is deficient in magnesium. Magnesium deficiency can drive down vitamin D conversion as well as cause a poor vitamin D repletion in the body. 

At PROCEED we add a highly bioavailable form of magnesium, Magnesium malate, to our D Synergy to provide optimal benefits from the supplement. Magnesium malate is shown to be one of the most bioavailable forms of magnesium available (see: The 9 Best Magnesium Supplements (healthline.com)).

How Much Vitamin D Should I Take?

You should take just 1 capsule of our PROCEED Synergy D daily with a meal, or as directed by your health care practitioner!

Our Synergy D provides 4,000 IUs of vitamin D, along with clinically relevant dosages of vitamins A and K, and vitamin E isomers. The formula is designed to support balance when supplementing these fat-soluble micronutrients, which function in intricate inter-relationships with each other. High-dose supplementation of only one of the fat-soluble vitamins could lead to a relative deficiency of other fat-soluble vitamins and result in unwanted side effects.

Does Boron Help Vitamin D?

Boron acts as a cofactor for vitamin D, meaning it helps the body use or absorb vitamin D by increasing the level of vitamin D in the blood. Boron increases the biological half life of vitamin D and is important for optimal calcium absorption, which helps in supporting bone density! (see: Nothing Boring About Boron - PubMed (nih.gov))

More about Boron:

Boron is a trace element that plays an important role in numerous biological functions, including calcium metabolism, growth and maintenance of bone tissue. Boron may influence the metabolism of various nutrients and steroid hormones, such as 1.25 (OH) 2 vitamin D, testosterone and 17- β estradiol, making it a vital addition to an effective, safe and comprehensive vitamin D supplement.  This role would be particularly evident in case of insufficient dietary intake of vitamin D, magnesium or both. (see: Pivotal role of boron supplementation on bone health: A narrative review - ScienceDirect)
