FAQ

What is Prop 65 and why does it appear on some of your products?

+-

The warning on the product is the result of a California law, called Proposition 65 which requires labeling if a product contains more than 0.5 micrograms of lead per daily recommended dose. It takes 1000 micrograms (mcg) to equal 1 milligram (mg.). Lead is naturally found in the environment and in the soil and water so vegetables and crops may have traces naturally. Our products contain many natural herbs and vitamins. It is therefore possible that, from time to time this substance may be present (naturally occurring and a portion contributed by lead in the air, soil, and water due to industrialization). To put the limit in perspective, the World Health Organization has set 243 micrograms of lead per day as a safe level, which is nearly 500 times the limit contemplated under California’s Prop 65. Although only products sold in California require this warning, we are committed to transparency and include it on all products that contain more than 0.5 micrograms of lead per daily recommended dose – even those sold in states that don’t require labeling. Proposition 65 warnings are ubiquitous throughout California on everything from supplements to wine bottles to restaurants and hospital cafeterias.

What is the advantage of taking a soft-gel over a tablet or capsule?

+-

They are generally easier to swallow and unlike other forms of delivery such as tablets and capsules do not contain binders and fillers that may cause stomach upset and offer no nutritional value.

What is BioPerine® and what does it do?

+-

BioPerine is an extract of Black Pepper. A U.S. patent and several clinical studies have demonstrated how it enhances the bioavailability and absorption of many nutraceuticals. We use it in our special BioPerine Complex, which takes BioPerine one step further by combining it with a powerful Ginger extract for enhanced digestion.

Can I take your products if I am on any medications or have any medical conditions?

+-

If you have any medical conditions or are currently taking medication, consult a licensed healthcare provider before using any dietary supplement. Prescription medication, just like any medication may interact with the ingredients found in a dietary supplement.

What is your product’s shelf life?

+-

Most of our products have a two-year shelf life. The expiration date is set as a guarantee that the product will contain the same levels of active ingredients as it did when manufactured until this date. After the expiration date we cannot guarantee that a given product will contain the potency of ingredients listed on the supplement facts panel. The expiration date is always printed onto our products.

What measures do you take to ensure the quality of your products?

+-

All of our products are quality assured. We employ compliance testing to ensure potency and purity. We are located in California and all of our products are completed here in the U.S.A. We are compliant with regulations.

Can I take more than one of your products at the same time?

+-

Before taking any dietary supplement you should always consult your health care practitioner if you are using any medications or have any medical conditions. If you are considering using multiple products at the same time look for ingredients the products have in common. Using products that have shared ingredients at the same time will increase the concentration of those ingredients. For example, taking multiple products that contain caffeine will increase the amount of caffeine you take at one time and could make you feel jittery or make it difficult to get to sleep at night.
