Supplement reviews by ConsumerLab – Vitamin D, Magnesium, Vitamin K, Calcium , Boron – Nov 2019

ConsumerLab provides, by far, the best supplement reviews on the web
A typical 40 page review has the following sections:

• What It Is What It Does
• Quality Concerns and What CL Tested For What CL Found
  • CL confirms that the amount stated is actually in the supplement
  • CL checks that there are no contaminates
• Top Picks
• Test Results by Product
• What to Consider When Buying What to Consider When Using Concerns and Cautions
• How Products Were Evaluated

Pros:

1. Typically the reviews will show the cost per unit of measure
   • (say 5 cents per 5,000 IU of vitamin D)
2. Good review of the literuare as to the benefits and side-effects of each supplement
3. They show the cost per unit meaure of a supplement
   • maximum cost of a supplement will often be 20X of the minimum cost
4. They frequently update each review - popular ones are updated several times a year
5. They have a 5 day free trial

Cons:

1. Suppliers must pay to have their products reviewed, so CL typically only reviews a fraction of what is on the market, and sometimes not the most popular products at that.
2. They often consider bio-availability of the different products
   • e.g. Magnesium, Calcium, Omega-3, oil form of Vitamin D
3. They do not seem to consider interactions (positive or negative) between supplements - examples:
   • Vitamin D and Calcium
   • Vitamin D and Omega-3
   • Vitamin D and Magnesium
   • Vitamin D and Resveratrol
   • Vitamin D and Vitamin K
4. You can only subscribe to all of their reviews - you cannot buy an individual review
   • $48/year - with a discount for 3 year contract
