Other Ingredients

Recognizing that superior bioavailability, efficacy and safety are the hallmarks that differentiate the best ingredients from many of those commonly supplied to the nutrition industry, Nutrition 21 offers a select group of premium quality ingredients to the trade. These include:

SelenoPure® L-selenomethionine (yeast-free)
Selenium is an essential trace element that is involved in the body’s defense against free radicals, the regulation of thyroid hormones, and cell recovery. Selenium is essential for immunity.

Current research indicates that L-selenomethionine is the only selenium compound that is incorporated into our body proteins and stored in tissues. Selenomax® High Selenium Yeast and SelenoPure™ L-selenomethionine are excellent ingredient choices for supplying L-selenomethionine. Both are natural, highly bioavailable, offer excellent stability and have no known incompatibilities with other nutrients.

SelenoPure™ is more compressible, and therefore, the preferred choice when incorporating selenium into multi-ingredient formulations for antioxidant supplementation; men’s health; prostate health; colon health and general health.

Zinmax® zinc picolinate
Zinc is an essential mineral vital to metabolism. Zinc is incorporated into over 200 zinc metalloenzymes that have been identified in the body’s systems. Zinc enzymes are involved in: protein metabolism; energy production; gene regulation; and maintaining the health of cell membranes. Zinc is vital for: growth and development; sexual maturation and reproduction; dark vision adaptation; smell and taste function; insulin storage and release; immune function; sperm health; wound healing; and mental health.

When dietary minerals are combined with picolinic acid, a natural metal chelator found in breast milk, they are better utilized at the body’s absorption sites. Utilizing the outstanding bioavailability characteristics conferred by picolinic acid, Zinmax® zinc picolinate is often included in the following formulas for: immune support, vision health, pregnancy (when doctor-approved), sexual health, fertility, arthritis support, and children’s health. Zinmax® zinc picolinate also makes an excellent ingredient choice when formulating a stand-alone zinc supplement.

Magnemax® manganese picolinate
Manganese is an essential trace element believed to be critical for: growth and development; reproductive function; vision; insulin metabolism and glucose tolerance; lipid metabolism; free-radical defenses; nerve health, proper blood clotting; cellular energy production; and muscle health. Manganese may also be beneficial for the health of hair and nails.

Utilizing the superb bioavailability characteristics conferred by picolinic acid, Magnemax® manganese picolinate is often included as an ingredient in such dietary supplement formulas for: joint health, sexual health, vision, glucose support, antioxidant, wound support, energy formulations for; strength training and sports, and supplements for skin, hair and nail health.
