Products & Ingredients
What forms of folate does Priority One use?
Where clinically appropriate, we use Quatrefolic® (5-methyltetrahydrofolate glucosamine salt), the most bioavailable form of active folate available. This is the form found directly in products such as Hemo-X, rather than synthetic folic acid which requires conversion by the body.
Do your products contain glandular concentrates? Where do they come from?
Yes, select Priority One products such as Thyroid 65mg and Total Gland Plus contain grass-fed, freeze-dried glandular concentrates. These are sourced from animals raised without hormones or antibiotics, and are prepared to preserve the natural integrity of the tissue.
Are Priority One supplements vegetarian or vegan?
Many of our products use vegetarian capsules. Product-specific dietary information including capsule type, common allergens, and suitability for vegetarians is listed on each product page. Products containing glandular concentrates are not suitable for vegetarians or vegans.
