Amen Clinics Vitamin D3 Review – 8 Things You Should Consider
Vitamin D3 is a dietary supplement based on the active nutrient vitamin D (in one of its forms also known D3 or cholecalciferol).
The formula is offered by Amen Clinics, a company founded by M.D. Daniel Amen. He is a well-known physician and psychiatrist considered to be one of best researchers and practitioners in the field of brain imaging. He is the leader researcher of a study involving professional football players that shows how the brain is damaged and what the solutions are towards significant recovery. Amen Clinics seeks to provide the most advanced nutritional solutions, specialized help and support programs in order to help people achieve the desired health. The clinic is in possession of the world’s largest database of functional brain scans related to behaviors.
Vitamin D3 is advertised as a solution to providing your body with proper amounts of vitamin D3, which cannot usually be synthesized in sufficient amount just from the foods we consume. The supplement is an important help for people who want to prevent the negative effects caused by a deficiency in this nutrient. It is well-known that vitamin D plays a crucial role in maintaining healthy bones by facilitation calcium and phosphorus absorption.
It is not clear if the formula is also suited for children or not. No precautions are issued by the manufacturer in relation to Vitamin D3.
1) Quick Overview
Vitamin D3 is a vitamin-based nutritional supplement.
Vitamin D is a fat-soluble vitamin occurring naturally in foods like fatty fish, dairy products, oysters and fortified food like cereals, soy milk or margarine. However, it can be difficult to get the proper amounts of vitamin D only from dietary sources. The nutrient contained by the nutritional supplements designed to provide the additional quantities comes in two forms: as vitamin D2 or as vitamin D3. Vitamin D3 is also called the “sunshine vitamin” because it can be easily synthesized by proper exposure to sunlight.
This nutrient is used to assist with certain health concerns like chronic disease, rickets (in children), osteoporosis, psoriasis, low blood calcium levels, etc. It may also be effective in promoting cellular health and assisting normal cell growth, regulating blood pressure, boosting the immunity, reducing the risk of rheumatoid arthritis, and preventing any type of cancer.
A daily dose of 4,000 IU should not be exceeded. Vitamin D toxicity causes over absorption of calcium leading to hypercalcemia, a buildup of calcium in the blood. This condition manifests itself through symptoms like: poor appetite, nausea, frequent urination, and even kidney problems. Higher doses are used when a vitamin D deficiency needs to be treated, but this is done only under specialized care.
Vitamin D3 from Amen Clinics is not clinically researched and no reviews from potential consumers were available. No side effects are mentioned for the formula either. These are two of the main reasons why the effectiveness of this formula couldn’t be determined.
2) What’s Inside Vitamin D3?

3) Does Vitamin D3 Work?
The formula is a vitamin-based nutritional supplement.
Vitamin D is a fat-soluble vitamin that occurs naturally in several foods such as mackerel, herring, sardines, tuna, cod liver oils, or eggs. However, a great way to assimilate the proper amounts of vitamin D is from sun exposure. Because it cannot be synthesized in sufficient quantities by the body (and must be obtained by diet or sun exposure), vitamin D is not considered a vitamin in the strict sense. However, because the risk of developing cancer due to prolonged sun exposure is considered a real threat, there are no recommendations issued by the Institute of Medicine. The vitamin presents several other noticeable benefits: inadequate levels have been linked with depression, Alzheimer’s disease, or bipolar disorder.
Vitamin D is believed to be helpful in preventing chronic disease, regulating cellular growth, promoting cellular health, reducing swelling, boosting immunity, and controlling blood pressure. Lack of vitamin D leads to low levels of calcium and phosphorus, and improper mineralization of the bone, causing rickets in children and osteomalacia in adults.
Doses higher than 4,000 UI per day may cause over-absorption of calcium. Excess of vitamin D may lead to side effects like loss of appetite, metallic taste, nausea, vomiting, headache, sleeplessness, etc. Pregnant and breastfeeding mothers should not exceed the same limit of 4,000 UI per day. People who suffer from kidney disease, sarcoidosis, or histoplasmosis should use vitamin D cautiously.
Certain drugs like most of the antacids and water pills interact with vitamin D.
The suggested use is for this supplement is one tablet daily or as directed. There is no mentioning if the formula is suited only for adults or if it is also suited for children or teenagers.
