How to cope with inventory shortages

The numerous inventory shortages caused by the pandemic have become a frustrating reality for both merchants and consumers. Unfortunately, it looks like they will be a part of our daily lives for a while. Here are some tips that we hope will help you get through the turmoil:

  1. Order early. Don't wait to finish a product if you want to keep taking it.
  2. Order two or three units of a product if you plan to take it for a long time. It may not be available the next time you need it.
  3. Ask your health care professional to suggest one or two alternatives for each product he/she recommends you take.
  4. Because of their higher quality standards, some brands have more difficulty sourcing their raw materials than others. Here are a few brands that currently have a very low backorder rate (less than 5%) or return times: Ortho Molecular Products, New Roots Herbal, Metagenics, AOR, Alterra, HerbalGem, Pranarom, Viazen. Reduce the risk of disappointment by choosing these brands.

Product Details


Advanced B Complex Ultra is based on Advanced B Complex®, our award-winning favourite, with additional benefits for heart health, brain health, and energy. Advanced B Complex Ultra utilizes time-release technology to enhance absorption and provides the full spectrum of B vitamins, some of them in multiple forms, for superior efficacy in the body.

Advanced B Complex Ultra is formulated with niacin, the most active form of vitamin B3, and the most effective for heart health and cholesterol. It contains a safe dose of slow-release niacin to minimize the sensation of “flushing”. Advanced B Complex Ultra is unique in that it also contains Pyrroloquinoline quinone (PQQ), a B-vitamin-like nutrient that helps support brain health.

Advanced B Complex Ultra is perfect for anyone looking to get beyond the standard benefits of B vitamins.
