Behind the formula: Good Green Vitality

Why we chose Vitamin A: Retinyl Palmitate and Mixed Natural Carotenoids

When formulating products at Nuzest we select ingredients based on their quality and efficacy. While many supplements on the market only use beta-carotene as a source of vitamin A, we choose to include a combination of retinyl palmitate and mixed natural carotenoids for maximum bioavailability and benefit in Good Green Vitality. 

What is vitamin A?

Vitamin A is an essential nutrient required for life. The term ‘vitamin A’ refers to a family of fat soluble dietary compounds found as preformed vitamin A (retinol) in animal products (red meat, liver, eggs) and as provitamin A (carotenoids) found in deep yellow, green and red coloured fruit and vegetables. Provitamin A is converted into vitamin A in the body. There are three active forms of vitamin A in the body – retinol, retinal and retinoic acid. Both preformed and provitamin A must be metabolised to retinal and retinoic acid to support the vitamins numerous important biological functions.

The key benefits of vitamin A

Vitamin A supports a variety of biological functions and is highly involved in regulating growth and differentiation of all cells in the human body. Vitamin A plays an important role in: 

  • Embryo growth and development¹
  • Immune functions¹
  • Eye development and vision¹ 
  • Maintaining skin and mucous membrane health ³
  • Exhibiting antioxidant properties ¹ 
  • Iron function in the body

Vitamin A in Good Green Vitality 

Good Green Vitality includes vitamin A in the combination of retinyl palmitate and mixed natural carotenoids (including beta-carotene) from Dunaliella salina in the formula. 

Retinyl palmitate is an ester of vitamin A that is immediately converted to the active, bioavailable form in the body.  Dunaliella salina is a plant-based micro-algae and is a rich source of beta-carotene and antioxidants. A combination of the two ensures readily available vitamin A and easily absorbed retinol in the body. 

Retinyl palmitate is usually found in animal foods however it can also be produced in a vegan form, which is what has been included in Good Green Vitality. Unlike plant sources of vitamin A like beta-carotene, retinyl palmitate does not need to undergo additional processing and conversion to the bioactive form of vitamin A in the body. Retinyl palmitate tends not to be found in other leading products, however it is a vital ingredient in our formulation due to its high bioavailability. 

Good Green Vitality uses a mix of carotenoids to ensure a wide range of therapeutic benefits are achieved. Most dietary supplements use beta-carotene as their only source of Vitamin A, and therefore miss out on hundreds of other important carotenoids. Whilst beta-carotene provides the most benefits, the other carotenoids also have important roles in the body. 

Nuzest produces the cleanest, most effective nutritional supplements on the market. All products are built on concrete science and efficacy, and are formulated to improve and support overall health and vitality. The entire Nuzest range is vegan, all-natural and free from nasties.
