Vitamin D as an oral solution, capsule or liquid.
Invita D3 is a simple and highly effective way to prevent your vitamin D levels from dropping, or treating severely low levels that can cause health problems.
Prescription dosages of Invita D3 are available at Treated. You just need to talk to us about your health and one of our registered clinicians can offer the most suitable treatments tailored for you. On top of this, our subscription service means you can get your supplement delivered regularly.
Invita D3 is a vitamin D supplement or treatment that is available as a capsule, oral solution or drop. It can be taken to help maintain good levels of vitamin D in your body, to help keep you healthy through the dark winter months.
Vitamin D is one of the body’s essential vitamins and minerals. It helps keep muscles, teeth and bones healthy.
When the sun isn’t shining it’s sometimes more difficult to get enough vitamin D in our systems. What’s more, the darker your skin, the harder this becomes. Vitamin D deficiency has actually been called an ignored epidemic by some health officials.
Invita D3 is essentially vitamin D. Its active ingredient, colecalciferol, is processed in the body as vitamin D, which helps you to fight off fatigue and keeps up your calcium levels. If you’re not getting enough sunlight, whether because it’s winter or you’re just not the outdoors type, then the lower doses of vitamin D will act as a preventative measure against your levels dropping too low. If you already have severely low levels of vitamin D, then it can be used as a treatment, although this will require higher doses.
Invita comes in many dosages, some for use as a supplement and some for use as a treatment. Invita D3 800 IU and 400 IU dosages are supplements and should be taken once a day, every day. The stronger doses are prescription medications. Which one you’ll be prescribed will depend on how severe your lack of vitamin D is and what it’s being prescribed to treat.
Invita D3 20,000 IU dosages are a common treatment, but strengths go as high as 50,000 IU.
There are also 5,600 IU capsules for less severe vitamin D deficiency.
