Nutritional Supplements What to look for before buying
Read and understand the label What form is the mineral in? Citrate, acetate, gluconate, oxide, etc Organic forms (citrates, acetates etc) generally better than inorganic forms (oxides, carbonates etc) How many capsules / tablets are there? What is the potency per tablet? What are the additional (non-active) ingredients?
Which is better value for money? ZINC CITRATE 15mg 100 capsules 15mg Zinc as Citrate 60 capsules £4.99£6.99
Additional Ingredients Fillers, binders, lubricants, emulsifiers, preservatives, coating agents, anti-caking agents –eg, Lactose, sucrose, corn starch, sodium chloride, talc, soap, waxes, dicalcium phosphate, magnesium stearate, stearic acid, microcrystalline cellulose, etc Introduces undesirable substances into the body Can upset the mineral balance of the prescription May be difficult for the digestive system to break down and obtain the nutrients Capsules have less additional ingredients Capsules easier broken down by digestive system
Beware of Marketing Marketing literature may not be written by qualified nutritionists Clever wording designed to sell / make profit Beware of vague wording such as “complex” “formula” or “blend” Patented products not necessarily effective Several companies may buy products from the same manufacturer and repackage
Timed Release Supplements May be useful for water soluble vitamins May be useful for water soluble vitamins Coatings may hinder absorption Coatings may hinder absorption Generally more expensive and benefits not always clear Generally more expensive and benefits not always clear Food Form Mineral is delivered with natural co-factors to enhance absorption and utilisation Mineral is delivered with natural co-factors to enhance absorption and utilisation Scientific evidence is lacking in this area Scientific evidence is lacking in this area No clear evidence that these can outperform citrates. No clear evidence that these can outperform citrates. Metallic minerals usually chelated with an amino acid Metallic minerals usually chelated with an amino acid Better absorbed within the body than inorganic minerals Better absorbed within the body than inorganic minerals Scientific evidence comparing them to organic forms is lacking Scientific evidence comparing them to organic forms is lacking Chelated minerals Liquid Supplements Often low potency – poor value for money Often low potency – poor value for money Likely to be destroyed by stomach acids Likely to be destroyed by stomach acids May be beneficial to those who are unable to swallow tablets May be beneficial to those who are unable to swallow tablets Other Types of Supplements
Independent testing Potency Stability Contamination (heavy metals) Yeasts / Moulds / Bacteria Chemical solvents / pesticide residues If in doubt ask the company if they can provide independent test results for their products
Signs of a good company Check the company website for details of manufacturing processes / quality assurance etc Trained nutritionists will be available to answer any questions you have about their products Products should have been independently tested and chemical assays available A good company will provide scientific research to back up the claims for its products Some companies run seminars or workshops which are educational – not just a sales technique
Problems with cheap products Fillers and binders may upset the mineral balance or hinder absorption Could contain impurities which result in allergic reactions May contain heavy metals / chemicals which increase toxic load in the patient May not contain as much of a particular nutrient as is stated on the label Potency not adequate for therapy Likely to use cheap forms of minerals with lower absorption Storage may not be adequate eg for fish oils / probiotics
Implications for therapy Lack of results reduce confidence in the practitioner –patient is less likely to stick to the diet or take further advice Results may be slower than expected –the patient may become impatient, lose motivation and give up the treatment Allergies may be triggered Mineral imbalances may be caused or worsened Toxic load may be increased

Summary Check labels carefully Use reputable suppliers Beware of fillers and binders Don’t be fooled by clever marketing Beware of excessively cheap products You generally get what you pay for Ask for research to support claims for products If in doubt ask for independent test results If it seems too good to be true it probably is!
