Got Questions?

Toggle Answer

How should I take vitamin D3 potency+?

Take 1 gelcap at any time during the day with or without food, or as directed by your health care practitioner. Store tightly sealed in a cool, dry place without direct sunlight. If you are pregnant or breastfeeding or planning to become pregnant, out of an abundance of caution, we recommend consulting your health care practitioner before using vitamin D3 potency+ or any dietary supplement product. Keep out of reach of children.

Toggle Answer

At what time of day should I take vitamin D3 potency+?

You can take vitamin D3 potency+ at any point in the day with or without food. The absorption of this essential fat-soluble vitamin is naturally supported with our built-in trio of organic oils (avocado, flaxseed, and extra virgin olive oils). Some customers may choose to take vitamin D3 potency+ along with their calcium supplement, since vitamin D3 is known to support calcium absorption in the body.* 


Toggle Answer

What is the vitamin D3 content per serving in vitamin D3 potency+?

vitamin D3 potency+ features 5,000 IU of vitamin D3 per serving (just 1 gelcap). This excellent source of vitamin D is intended to support healthy vitamin D levels in our body (i.e., 25-hydroxyvitamin D) and when taken daily, help maintain this vitamin D sufficiency over the long term.*

Toggle Answer

Why did you include organic oils in vitamin D3 potency+?

We carefully built in three high-quality organic oils (organic avocado, flaxseed, and extra virgin olive oils) to support the bioavailability of our hero ingredient (organic, algal vitamin D3) in the body. Our unique trio of organic, virgin oils provide over 400 mg of healthy unsaturated fatty acids in each gelcap. These unsaturated fats include healthy omega-3 and omega-9 fatty acids, which deliver the added bonus of their antioxidant and anti-inflammatory properties known to support cardiometabolic and overall health.*

How is your vitamin D3 source different than most vitamin D supplements?

1. Premium ingredients: We chose to use premium vitamin D3. It’s from a sustainable algal source. It’s vegan and certified organic. Organic vitamin D3 is rare. Organic, sustainably sourced algal vitamin D3 is extremely rare. We also chose 3 premium, organic oils (organic flaxseed, avocado, and extra virgin olive oils) to complement this premium vitamin D3.

2. Potency: mbg vitamin D3 potency+ was specifically designed as a daily essential for life, formulated with a clinically effective dose (5,000 IU) in most adults. Many vitamin D products on the market contain sub-efficacious doses.

3. Form: This smart vitamin D3 supplement is delivered in our body's preferred form (vitamin D3, not vitamin D2), which is known to have superior bioavailability.

4. Built-in absorption technology: We engineered an innovative ingredient combination, with vitamin D3 plus organic oils. This all-in-one technology designed to be taken anytime of the day, with or without food. It's rare to find a vitamin D3 supplement with a built-in profile of healthy fats, much less a trio of carefully curated organic oils that deliver healthy omega-3 and omega-9 fatty acids to support vitamin D's natural absorption in the body.  

Toggle Answer

Is vitamin D3 potency+ vegan?

No, because the vitamin D3 potency+ gelcap is gelatin, this supplement is not vegan. The four active ingredients are vegan (i.e., the organic, algal vitamin D3 and three organic oils), but their gelatin casing ultimately means the final product is not technically vegan.
