Since B vitamins are found in many foods, you are most likely not at risk of developing a deficiency as long as you follow a well-rounded diet.

Pullar JM, Carr AC, Vissers MCM. The roles of vitamin C in skin health. Nutrients. 2017;9(8):866. doi:10.3390/nu9080866 Some research has found that supplementing with vitamin C can shorten the duration of a cold and may help prevent and treat other infections, such as tetanus and pneumonia. But more human studies are needed ( 4). Mineral ascorbates such as calcium and magnesium ascorbate are often called ‘buffered’ vitamin C. Many people find these to be gentler forms of vitamin C that are better tolerated by the gut. It is important however to consider the accompanying dose of mineral (calcium, magnesium etc.) when taking higher levels. Vitamin C Complex contains Food Based vitamin C and zinc which contribute to the normal function of the immune system, protection of cells from oxidative stress and normal function of the immune system during and after intense physical exercise. Food Based vitamin C is made using real citrus fruits and our Vitamin C Complex is boosted with a high extract ratio chaga mushroom from the fruiting body (part above the ground) of the mushroom. Fruiting body mushrooms are a rich source of protein-bound polysaccharides, alpha and beta-glucans. Bioflavonoids (or flavonoids) are polyphenolic compounds found in plants, and are especially plentiful in vitamin C-rich plant foods. There are around 5,000 different varieties of flavonoids and they are made by plants in response to microbial infection. You will often find vitamin C and bioflavonoids together in a synergistic supplement formula. This is because some research has found that the addition of flavonoids may help to increase the absorption of vitamin C from supplements; other studies however have found there to be no difference. 14-19Jones E, Hughes RE.

Bull. 2011; 34:1744 – 1747. During pregnancy, the demand for B vitamins, particularly B12 and folate, grows. This is because they are needed to support fetal development ( 9). While certain conditions make it necessary for some people to supplement with B-complex vitamins, research has shown that taking a B vitamin supplement may be helpful even for people who don’t have an increased need for these nutrients.

Vitamin C intake is a poor surrogate for vitamin C status as the estimation of vitamin C intake is inherently inaccurate and the relationship between intake and status is highly complex.

Riboflavin helps convert food into energy and also acts as an antioxidant. Foods highest in riboflavin include organ meats, beef, and mushrooms ( 2). Studies have shown mixed results,” Peart notes, “but we know that vitamin C acts as an antioxidant for cells in the retina and macular region of the eye.” 3. Improves iron absorption
