If you don’t like something of ours, guess what happens next?

No, we don’t request you deliver it to a PO box in the Gobi Desert by carrier pigeon. Nor do we ask you to fill a cursed inkwell with orc’s blood and demon saliva and then use it to complete reams of return forms written in ancient Cyrillic script.

We just . . . wait for it . . . give you every penny of your money back. Holy moo cows. And that means you can say "yes" now and decide later.

Legion Vitamin B Complex Ingredients (685.6 milligrams per serving)

8 Essential Vitamin B Vitamins (85.6 milligrams per serving)

Vitamin B Complex contains clinically effective doses of all eight essential B vitamins that are vital for many aspects of health, performance, and wellbeing, including metabolism; brain, nervous, and DNA health and function; cellular growth and repair; hormone production, and more.[7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61]

Choline (250 milligrams per serving)

Choline is an essential nutrient that was formerly considered a B vitamin (B4) but now is recognized as a distinct substance. It’s found in foods like meat, fish, nuts, beans, vegetables, and eggs, and it’s vital for brain, nervous, and liver health and function.

Research shows that supplementation with choline . . .

While it’s possible to get enough choline through your diet to support optimal health, it can be difficult because it requires eating adequate amounts of foods that many people don’t eat, including eggs, liver, and peanuts.

This is why research shows that up to 94% of women and 89% of men in America don’t consume the minimum amount of choline needed to support health.[66]

There is no recommended daily allowance for choline, but the U.S. Food and Nutrition Board has set an Adequate Intake (AI) level of 550 milligrams per day for adult men and 425 milligrams per day for women.

Inositol (250 milligrams per serving)

Inositol, also (now erroneously) known as vitamin B8, is a group of molecules involved in cellular signaling and the health and function of cell membranes.

While it’s possible to get enough inositol through your diet to support optimal health, it can be difficult because it requires eating adequate amounts of foods that many people don’t eat, including citrus fruits, whole grains, beans, nuts, and green leafy vegetables.

Research shows that supplementation with inositol . . .

There is no recommended daily allowance for inositol, but it’s often suggested that adult men and women consume approximately 1-to-4 grams per day to support health.

Coenzyme Q10 (100 milligrams per serving)

Coenzyme Q10 (CoQ10) is a substance that helps enzymes perform bodily processes (hence “coenzyme”). It’s found in a variety of foods, especially organ meats such as heart, liver, and kidney.

It’s present in every cell of the body, particularly in the mitochondria (the “powerhouses” of the cells), and it plays a crucial role in the production of cellular energy and functions as an antioxidant.

Moreover, as cellular CoQ10 levels decline with age, scientists believe that this circumstance may contribute to the development of age-related disorders, including the aging process itself.[70][71][72][73]

Research shows that supplementation with CoQ10 . . .

  • Reduces oxidative stress[74]
  • Enhances antioxidant protection[75]
  • Supports healthy inflammation levels[76]
  • Boosts physical performance and recovery[77][78][79]
  • Improves male fertility[80]

The clinically effective dose of CoQ10 is 50-to-200 milligrams.

No Artificial Food Dyes, Fillers, or Other Unnecessary Junk

Artificial food dyes and fillers may not be as dangerous as some people claim, but studies show they can cause negative effects in some people, including gastrointestinal toxicity and behavioral disorders.[81][82][83][84][85]

That’s why we use natural coloring derived from fruits and other foods as well as naturally derived ingredients for enhancing shelf life and facilitating the manufacturing process.
