1) Quick Overview

Vitamin D3 1000 IU Sunny Gummies is a vitamin formulation, free of artificial colors, flavors, sweeteners, preservatives and other objectionable additives often found in gummy vitamin products.

Vitamin D3 is synthesized from cholesterol, under sun exposure, but can also be taken from foods such as cod liver oil, chicken liver or eggs. Vitamin D3 is the only vitamin the body can manufacture from exposure to direct sunlight (UVB). However, recent concerns about skin cancer caused by sunlight exposure resulted in an increase in Vitamin D deficient people.

Deficiency of Vitamin D can trigger a large number of disorders and imbalances which may manifest as back pain, easy bone fractures, macular degeneration depression, cancer, pre-eclampsia during pregnancy and insulin resistance. On the other hand, overdose of vitamin D may lead to fatigue, headache, loss of appetite, sleepiness or nausea.

Vitamin D most important role is in the bone and immune system health, but also in several heart and blood vessels conditions (hypertension or heart disease). Vitamin D regulates the levels of Phosphorus and Calcium in the body.

3) Does Vitamin D3 1000 IU Sunny Gummies Work and it is Safe?

As a vitamin formula, Vitamin D3 1000 IU Sunny Gummies is promoted as a product for individuals who lack this ingredient due to bad eating habits, sun lotions, environmental factors, or other factors such as aging. It seeks to establish better levels of its main component in order to enhance the muscular and skeletal system while also having a positive effect on immunity.

Research revealed that Vitamin D3 is naturally synthetized under sun exposure, from cholesterol. However, it can also be consumed through some foods like eggs, chicken liver, or cod liver oil. Some individuals lack it from their organism in a worrying way. Thus the adverse effects that have appeared due to this include problems such as macular degeneration, back pain, depression, or insulin resistance. Therefore, to compensate for these unbalances, they would have to try to obtain it from other sources such as dietary supplementation or prescribed medication.

Its core role in the body is linked to the immunity and bone health, but it also has an impact on blood vessels and some heart conditions such as heart disease and hypertension. Another reason behind its importance is related to regulation of minerals like calcium and phosphorus.

Possible side-effects that appear during the utilization of this product include loss of appetite, headaches, nausea and sleeplessness.

I gave this supplement to my 10 year old daughter because she was having troubles absorbing calcium. After two weeks, I’ve noticed some improvement.
