Best Source Naturals Enzyme Supplements in 2026

ZINC MONOMETHIONINE BENEFITS. Source Naturals OptiZinc is zinc monomethionine, a patented combination of zinc and the essential amino acid methionine. Research shows this formulation makes zinc more absorbable than other zinc compounds and therefore more readily available for the body’s needs.

WHY IS ZINC IMPORTANT? Zinc is a trace mineral that plays many important roles in health: it supports skin health and wound-healing; it is essential for carbohydrate metabolism; it’s necessary for over 100 different enzyme systems, for proper vision, growth, skeletal integrity, tissue repair, sexual maturity; and it is an important antioxidant.

SUITABLE FOR VEGETARIANS. Contains no yeast, dairy, egg, gluten, corn, soy or wheat. Contains no starch, preservatives, or artificial color, flavor or fragrance.

SUPPORTS CARDIOVASCULAR HEALTH. Research suggests that healthy homecysteine levels play a role in cardiovascular health. Enzymes support healthy homocysteine levels in the blood and many are dependent on vitamin B-6.

ULTRA-MAG BENEFITS. Ultra-Mag uses a complex blend of highly bioactive forms of magnesium—citrate, taurinate, malate, glycinate and succinate— to provide all of the benefits that magnesium offers. In addition to supplying 100 percent of the body’s daily magnesium needs, our formula includes vitamin B-6 to further support cardiovascular health.

ABOUT SOURCE NATURALS ULTRA MAG. Contains no yeast, dairy, egg, gluten, soy or wheat. Contains no sugar, preservatives, or artificial color, flavor or fragrance.

Ultimate Protection. It is a critical component of an enzyme that generates acetyl coenzyme A, the start of the Krebs cycle that produces ATP in the mitochondria. ATP is the main source of energy for all muscle contractions and almost all other activities that our cells perform. Most of all, ALA is recognized as a powerful antioxidant because it has the unique ability to reactivate helpful compounds like vitamin C, glutathione, vitamin E, and CoQ10, enabling them to do more for your health.

Support Your Body With Antioxidants. It is a potent antioxidant and is active in both fat- and water-soluble regions of the cells. This makes ALA quite rare and this is why it is called “the universal antioxidant.” ALA also supports healthy sugar metabolism, liver function and energy generation.

A Highly Effective Antioxidant. ALA scavenges and terminates free radicals. The quenching of free radicals is a highly important aspect of healthy aging and immune health. ALA is a potent reducing agent and can reactivate other helpful antioxidants like vitamin C, vitamin E, and CoQ-10.

B-Vitamin Benefits. Essential components of numerous key enzyme systems, without which the body cannot function. Each B-vitamin fills a different complementary need, which is why they should most often be taken together. B-vitamins act as coenzymes to catalyze numerous biochemical reactions

Suggested Use. 1 tablet 1 to 2 times daily.

Well Made Supplement. This tablet is packed with b-vitamins such as b-1, b-2, b-6 and much more.
