The Herbs of Smoothie Essentials: Vitamin D2 (Ergocalciferol)

Standard

Add a boost with Calcium Blend, featuring Vitamin D.

Vitamin D2[1] – Ergocalciferol is a form of vitamin D, also called vitamin D2. It is marketed under various names including Deltalin (Eli Lilly and Company), Drisdol (Sanofi-Synthelabo) and Calcidol (Patrin Pharma). It is created from viosterol, which in turn is created when ultraviolet light activates ergosterol (which is found in fungi).

Ergocalciferol is widely used as a Vitamin D supplement, and a 2011 clinical guideline [2] considers it to be as effective as cholecalciferol (Vitamin D3), which is produced naturally by the skin when it is exposed to ultraviolet light. However there is now conflicting evidence regarding how similarly D2 and D3 behave in the body and whether they are equally potent. Some studies suggest D3 is more potent [3][4], but others have found that they are equally effective [5][6].

In the absence of adequate exposure to sunlight or equivalent light, dietary intake of vitamin D is required for maintenance of health. Vitamin D occurs naturally in fish and fish oils, eggs, liver and dairy products. The amounts naturally present in dairy products are generally inadequate to meet the requirements and vitamin D3 is added to evaporated milk, infant formulas, and to most fresh fluid cow milk solid by dairies.

In addition, vitamin D2 or vitamin D3 is commonly added to margarines, to certain breakfast cereals and to a few other foods. Fortification of milk with vitamin D3 since the 1920s has been credited with the marked reduction in incidence of rickets. [7]

The Herbs of Smoothie Essentials: Alfalfa

Standard

Add a boost with Green Blend, featuring Alfalfa.

Alfalfa has been traditionally used in Herbal Medicine as a nutritive tonic  (Meyer 1993, BHP 1983)[1][2]

Alfalfa ( /ælˈfælfə/; Medicago sativa) [3] is a perennial flowering plant in the pea family Fabaceae cultivated as an important forage crop in the US, Canada, Argentina, France, Australia, the Middle East, South Africa, and many other countries. The English name is adopted from the Spanish,

Originally alfalfez, which in turn is derived from the Arabic al-fisfisa “fresh fodder”. The Spanish name is widely used, particularly in the US but it is also known as lucerne in the

UK, Australia, South Africa and New Zealand, erba medica in Italy, meaning medical herb, luzerne in France, and lucerne grass in South Asian English. It superficially resembles clover, with clusters of small purple flowers followed by fruits spiralled in 2 to 3 turns containing 10-20 seeds.

Alfalfa is high in protein, calcium, plus other minerals, vitamins in the B group, vitamin C, vitamin D, vitamin E, and vitamin K.[4]

The sun-dried hay of alfalfa (also known as Lucerne) has been found to be a source of vitamin D, containing 48 ng/g (1920 IU/kg) vitamin D2 and 0.63 ng/g (25 IU/kg) vitamin D3. [5]
