Nutrition Geeks Vitamin D3 + K2

My Experience

Living in the UK, I really think everyone should be taking Vitamin D during the winter months. Even if you are outdoors often, there just isn't enough sun here to maintain healthy levels naturally.

Nutrition Geeks have nailed the value proposition here. You get a full year's supply at a budget price, but they haven't skimped on the ingredients. It combines Vitamin D3 with Vitamin K2 (specifically the superior MK-7 form). This is the best way to supplement because the D3 helps you absorb calcium, while the K2 ensures that calcium actually goes to your bones rather than sitting in your arteries.

However, since this is a high-strength budget option, I have a few tips to get the most out of it:

Watch the strength: At 4000 IU, this is the upper safe limit for daily use. I definitely wouldn't take these daily during the summer or if you get plenty of sun, as you want to avoid toxicity.

Take with food: Because these are dry tablets using generic fillers (to keep the price down) rather than oil-filled softgels, you must take them with a meal containing some fat. If you take them on an empty stomach, you won't absorb them properly.

Timing matters: Take them with breakfast or lunch. Vitamin D can suppress melatonin (your sleep hormone), so taking them at night might keep you awake.

Medical interaction: Since this contains Vitamin K2, consult your doctor if you are on blood thinners.

Overall, an easy 5 stars. It is a cost-effective way to support your general well-being, provided you use it correctly.
