Just a few additional benefits of Kids of Good Stuff

It’s a powder

Powder form allows for a larger serving size, meaning we can pack in more whole-food and super-food ingredients than you could fit into capsule or tablet products.

Preformed vitamin A, plus mixed carotenoids for enhanced effects

The most commonly used carotenoid in supplements is beta-carotene, a vegetable derived carotenoid that is converted into active vitamin A. However conversion rates of beta-carotene to usable vitamin A differ by a factor of nine-fold13 and beta-carotene is required in amounts at least four times higher than taking a pre-formed vitamin A.14, 15 For this reason, we have included both preformed vitamin A (from retinyl palmitate) along with sufficient beta-carotene (pro-vitamin A) and other naturally occurring carotenoids to ensure optimal vitamin A levels. We have also included a mixed carotenoid blend to cover a range of antioxidant and pro-vitamin A actions.

A better form of B12

We used methylcobalamin—a readily usable form of B12 in preference to the more common cyanocobalamin which requires conversion to a usable form.

Great levels of B vitamins

B vitamins are essential for creation of fuel within cells, and a host of enzyme reactions within the body. Kids Good Stuff provides more B vitamins than the leading multi-nutrient formulas for kids.

A better form of B9

In KGS we use the active methylated form of folate; L5 methyltetrahydrafolate (L5MTHF) in preference to the cheaper synthetic form often simply labeled ‘folic acid’. Many people cannot effectively convert other synthetic forms of folic acid to active folate in the body. The common syntetic form of folic acid (pteroylmonoglutamate) found in most supplements may also lead to high levels of unmetabolised folic acid in the blood3, 4. This can interfere with the function of active folate5, 6 and negatively affect immunity.7

Higher levels of immune-supporting Vitamin C

There is a big difference between ‘required’ and ‘optimal’ levels of vitamin C. Research suggests that higher than Dietary Reference Intake (DRI) doses of vitamin C, when taken consistently, can reduce the length and severity of the common cold.8

Broad spectrum vitamin E support

We use mixed tocopherols and tocotrienols in preference to the standard ‘alpha-tocopherol’ form, which while important may reduce levels of the other health-promoting forms of vitamin E in the body.9

Includes essential Vitamin K

Commonly ommited from kids formulas, Vitamin K plays an important role in promoting proper coagulation and wound healing. It is also involved in regulating immunity and inflammation and in aiding bone construction and development.

Includes Alpha-lipoic acid for increased antioxidant action

Alpha lipoic acid is a type of fatty acid that’s found in every cell and helps to generate energy. Alpha lipoic acid also functions as an antioxidant and unlike most antioxidants works in both water and fatty tissue and so has a broad spectrum of antioxidant actions.

Higher levels of potassium

Many people now eat diets that are quite high in sodium (from table salt and salt added to foods.) Potassium works with salt to preserve proper water balance within and between cells and so we need ample potassium to preserve this balance.

Selenium to support thyroid health

Selenium is an important antioxidant mineral. It works with vitamin E to protect cell membranes and as a co-factor for conversion of the thyroid hormone thyroxine (T4) to the more active form triiodothyronine (T3) is essential for a healthy metabolism.

Additional nutrient-dense whole food extracts

We also include many nutrient boosting whole-food ingredients lacking in many products. Foods such as marine algae extracts to provide natural, bio-available calcium, cacao and New Zealand blackcurrants (two of the foods highest in antioxidants), bromelain (an immune boosting enzyme), dandelion (a nutrient dense herb food), and pre and probiotics to support gut health and immunity.
