Ingredients (5,006 milligrams per serving)

Tinofend® Tinospora Cordifolia (900 milligrams per serving)

Tinospora cordifolia (also known as guduchi and amrit) is a shrub native to India that has been used in Ayurvedic medicine for centuries.

It contains molecules known as polysaccharides and terpenoids that increase the killing capacity of macrophages, which are cells that help destroy harmful bacteria and viruses.[9][10]

This is why research shows that supplementation with Tinospora cordifolia reduces nasal congestion and discharge and sneezing.[11]

The clinically effective dose of Tinospora cordifolia is 900 milligrams.

Tinospora Cordifolia

Panax Quinquefolius (900 milligrams per serving)

Panax quinquefolius (also known as American ginseng and North American ginseng) is an herb that grows mainly in North America and China and has long been used in traditional Chinese medicine.

It contains molecules known as saccharides that stimulate the immune system, improving its ability to fight off harmful invaders.[12][13][14]

This is why research shows that supplementation with Panax quinquefolius reduces cold and flu infection rates.[15][16][17]

The clinically effective dose of Panax quinquefolius is between 400 and 1,125 milligrams.

KaempMax® Thai Ginseng

Pelargonium Sidoides (800 milligrams per serving)

Pelargonium sidoides (also known as African geranium and black geranium) is an herb long used in traditional South African medicine.

It contains several molecules, including umckalin and related substances, that prevent bacteria from adhering to cells, making it harder for them to affect you.[18]

This is why research shows that supplementation with Pelargonium sidoides . . .

  • Dramatically reduces the duration and severity of acute bronchitis[19]
  • May reduce the duration and severity of the common cold[20]

The clinically effective dose of Pelargonium sidoides is around 800 milligrams of the raw plant.

Pelargonium Sidoides

Aged Garlic Extract (900 milligrams per serving)

Aged garlic extract is a substance made from garlic that has been aged for several weeks or months to reduce odor and enhance nutritional properties.

It contains an antioxidant known as S-allylcysteine as well as various molecules that supply the body with sulfur, and this aids the immune system by improving the body’s ability to fight off pathogens.[21]

That’s why research shows that supplementation with aged garlic extract reduces the severity of colds and flus and improves vitality and well-being when sick.[22]

Studies also show that supplementation with aged garlic extract provides other benefits, including . . .

  • Lower blood pressure[23]
  • Improved blood flow and arterial health, which reduces the risk of heart disease[24][25][26][27]
  • Improved cholesterol profile, which also reduces the risk of heart disease[28]
  • Increased activity of the antioxidant enzyme glutathione, which reduces oxidative stress in cells[29]

The clinically effective dose of aged garlic extract is between 600 and 1,200 milligrams.

Aged Garlic Extract

Zinc (6 milligrams per serving)

Zinc is a mineral used to create enzymes, proteins, and cells, release vitamin A from the liver, and regulate immune function.

It aids the immune system by enhancing the development and function of several types of cells that are vital to its operations.

This is why research shows that a zinc deficiency increases infection rates of various pathogens and supplementing with it when sick reduces the duration and severity of sickness.[30][31][32][33]

The clinically effective dose of zinc for the purposes of preventing a deficiency is 8 to 11 milligrams per day, and for reducing the duration and severity of sickness, 80 to 100 milligrams per day.

We chose to include a small amount of zinc per serving, however, for two reasons:

  1. It would prevent people from being able to take it alongside our multivitamin, Triumph which contains 30 milligrams of zinc per serving.
  2. The studies demonstrating zinc’s effectiveness when sick used lozenges, and we can’t be sure oral supplementation would be equally effective. If you’d like to bump up your zinc intake when around sick people or sick yourself, then, research shows that lozenges providing 80 to 100 milligrams per day is ideal.[34]
Zinc

Vitamin C (1.5 grams per serving)

Vitamin C is an antioxidant that helps maintain healthy tissues, teeth, and gums, promote wound healing, and boost immune function.

It aids the immune system by assisting with the development and function of several types of cells that are vital to its operations.

This is why research shows that an inadequate intake of vitamin C increases infection rates of various pathogens and supplementing with it when sick with the common cold reduces the duration of sickness.[35][36][37]

Studies also show that in athletes, daily supplementation of vitamin C reduces the risk of the common cold.[38]

The clinically effective dose of vitamin C for the purposes of reducing the duration of the common cold is between 1 and 8 grams per day, with higher doses generally used for the first day or two of sickness and followed by a lower daily amount.

And for athletes wanting to prevent sickness, the clinically effective dose of vitamin C is 1 to 2 grams per day.

Vitamin C

No Artificial Food Dyes or Other Chemical Junk

Studies show that artificial food dyes may cause negative effects in some people, including gastrointestinal toxicity and behavioral disorders.[39][40][41][42][43]

No Artificial Food Dyes or Other Chemical Junk
