Spectrumceuticals source ingredients from particular companies due to their patented products, good manufacturing practices (cGMP) and the integrity of their certificate of analysis and adherence to regulatory requirements.


Most nutritional dietary supplements contain some inactive excipients. In our formulas;

  • all excipients are casein and gluten free
  • capsules made from hydroxypropylmethylcellulose
  • HPMC consists of only two ingredients: HPMC and purified water. HPMC is derived from vegetable cellulose and contains no preservatives, gelatin, wheat, animal by-products or starch.
  • some of our formulations contain minute quantities of silicon dioxide
  • due to its anti-caking properties. Silicon dioxide is inert and non-toxic as a dietary supplement.
  • some of our formulations contain leucine

In cases where we cannot use leucine we use small quantities of vegetable-grade magnesium stearate as a lubricant for encapsulating our two-piece vegetable capsules. Lubricants prevent ingredients from sticking to the capsule-filling machine and stop ingredients from clumping together in a formulation.

When encapsulating probiotics it is important not to over heat the bacteria so lubricants are necessary for long term stability.

  • no flavours in any products to mask unpleasant-tasting active ingredients


All ingredients must clear both regulatory and internal benchmarks before passing.
We will supply practitioners with the latest allergens assay for the ingredients being enquired about.
In summary, you can be assured that Spectrumceuticals’ ingredients are tested for a range of heavy metals, pesticides, microbes, allergens and food intolerances by reputable laboratories with the capability and technology to accurately detect most contaminants.
