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.

Consult a health care practitioner prior to use if you are taking carbidopa or drugs/supplements with serotonergic activity.

Some people may experience drowsiness.

Exercise caution if operating heavy machinery, driving a motor vehicle or are involved in activities requiring mental alertness.

Some people may experience diarrhea, nausea, vomiting and abdominal pain.

Discontinue use and consult a health care practitioner if you show signs of weakness, oral ulcers or abdominal pain accompanied by severe muscle pain, or if you experience skin changes, or if symptoms persist or worsen.

Consult a health care practitioner if sleeplessness persists for more than 3 weeks, or if you are pregnant or breastfeeding.

Keep out of reach of children.

Combining serotonergic drugs such as antidepressants, dextromethorphan (in cough syrups), meperidine (Demerol), tramadol and others may increase the risk of serotonergic side effects such as serotonin syndrome.

Combining 5-HTP and carbidopa-levodopa (Sinement®) can increase the risk of serotonergic side effects.

Carbidopa is sometimes intentionally used with 5-HTP to minimize peripheral 5-HTP metabolism and boost the amount that reaches the brain. But this combination might also increase the risk of some side effects including hypomania, restlessness, rapid speech, anxiety, insomnia, and aggressiveness.

The combination of 5-HTP and carbidoba has also resulted in scleroderma-like skin reactions. Individuals using this drug combination or those who suffer from scleroderma should be monitored by a health care practitioner.

Anecdotally, 5-HTP may lower blood pressure and could be additive to antihypertensive drugs.

Sealed for your protection.

Do not use if seal is broken.

For freshness, store in a cool, dry place.
