Frequently Asked Questions About Vitamin D3

Q: How does an effective Vitamin D3 supplement work?

Vitamin D3 supplements are a more effective way to supply the body with Vitamin D and vanquish vitamin deficiency. Vitamin D is used for many roles throughout the body. However, it is most known for its effects on the skeletal, cardiovascular, and immune systems.

In addition to helping modulate the immune system, a D3+K2 supplement increases Calcium absorption and helps to calcify the bones. This protects the bones by both building them up and preventing the body from siphoning off bone Calcium to maintain equilibrium in the blood. Additionally, this process protects the arteries and kidneys from Calcium buildup which could reduce their flexibility. 

The correct formula holds the key to success so look for something that contains doses backed by scientific data that work to increase Vitamin D3 and K2 levels. The formula should not just contain the right ingredients, but also provide doses that have been proven effective and are backed by scientific research. 

Q: Do all D3+K2 supplements work?

Unfortunately, they do not. There are many shady companies that just go along with the latest health supplement trends, formulating supplements that contain unnecessary or inactive ingredients and the wrong potency or amounts. Often, they even add cheap fillers, binders, hormones, artificial colorings, or preservatives that can hinder the effects of the active ingredients. Do your homework and check the labels to make sure you are taking a quality product and not just some inactive powders in a pill. 

Q: What are the important points to look out for?

Vitamin D3 supplements should:

  • Contain 5000 IU (125mcg) of Vitamin D3, as recommended by the Vitamin D Council.
  • Include Vitamin K2, preferably as MK-7 which is active longer than MK-4 and more effective for directing Calcium into the bones.
  • Contain at least 80% Trans Isomer MK-7 which means that it is 80% biologically active.     
  • Provide 180mcg of Vitamin K2 MK-7 which is the clinically studied dosage.
  • Contain BioPerine® (or similar) to aid absorption, efficacy, and faster results.
  • Not contain any binders, fillers, additives, hormones, preservatives, or artificial ingredients.
  • Be 100% pure, natural and with no unnecessary ingredients that could reduce the effectiveness of the product.

Q: Are there any known side effects to look out for?

Of course, each product is different, so it is always wise to read the label thoroughly and follow the instructions carefully. Our research analyzed many products that generally do not present any side effects if used correctly. However, as with any supplement, we recommend consulting with a doctor if you are pregnant, breastfeeding, have an existing medical condition or are taking regular medication.

Q: What are the dosage instructions for D3+K2 supplements?

Again, this differs between products. Always read the label thoroughly and follow the instructions carefully. If you exceed the suggested dosage you could pose health risks to yourself. Generally, we found that most products suggest taking 2 capsules per day. Some people like to take the complete daily serving together, but we recommend spacing it out to achieve optimal benefits from the ingredients contained within the formula.

Q: How long before I start to see results?

Some consumers experience positive effects within a few weeks. For others, it can take longer. Everybody is different. Additionally, results will vary depending on other factors such as the type of diet you consume, your lifestyle choices, and genetic disposition. If you’re skeptical about seeing results, choose a provider who offers a complete money-back satisfaction guarantee as this indicates the manufacturer’s confidence in their product. 

Q: What should I expect to pay for a good Vitamin D3 supplement?

The cost of products varies among manufacturers. Unfortunately, many are cheap, useless supplements that have been formulated without any thought for safety or efficacy. Some of these companies are selling their products for around $100 per bottle, which is much too expensive. On average, the best supplements we found are selling between the $40-$50 price range. Oftentimes, a cheaper price is indicative of low quality or a low recommended serving, which will not be sufficiently effective. Be aware. Read the labels.

Q: Which Vitamin D3 supplement is the best one to buy?

Since each person’s experience of a product is different, it is difficult to say specifically which one is the best. That said, based on several factors, we did like Approved Science Vitamin D3+K2 the most. We found that from the 50+ products that we analyzed, Approved Science Vitamin D3+K2 had the best quality of ingredients, potency and strength, consumer feedback, and customer service.

Ultimately, the choice is yours. We hope that our research has gone some way in helping you make your choice. If you are looking for an effective product, we think you can’t go wrong with Approved Science Vitamin D3+K2. It is an excellent quality product, with great reviews and is well priced.
