Hypoallergenic supplements from Allergy Research Group, explained
Hypoallergenic is a formulation choice, not a marketing word
Allergy Research Group was founded in California in 1979 and built its range around one question: what can you take if you react to most supplements? The answer was to strip the formulas back. Common allergens such as gluten, dairy, soy, corn, egg and nuts are left out, along with added colours and needless fillers. The buffered vitamin C, one of the first products, pairs vitamin C with calcium and magnesium so it sits better in a sensitive stomach.
You can see that thinking in the ingredient lists. Capsules are usually plain vegetarian cellulose, most products hold one nutrient instead of a crowded blend, and the label names the source of each raw material. That makes the range easy to build with: you add what you need, rather than a multi that overlaps with everything else in your cupboard. If you want to weigh up the alternatives first, our overview of supplement brands shows what else we carry in the same forms.
What sits in this collection
- Buffered vitamin C in capsules and powder, for stomachs that struggle with plain ascorbic acid
- Essential-Biotic probiotics, including Saccharomyces boulardii, a yeast rather than a bacterium
- Optimox Iodoral, high-strength iodine tablets with potassium iodide
- Single nutrients such as NAC, TMG and zinc picolinate
- 200 mg of Zen, a combination of L-theanine and GABA
Two things are worth knowing before you order. Some products are not vegan: certain softgels use fish gelatin, and the glandular products are beef or pork based, so check the label if that matters. And hypoallergenic lowers the chance of a reaction, it does not remove it. If you react to an unusual ingredient, read the full list. Readers who mainly want gut support often begin with one probiotic supplement and add a second product weeks later, instead of three at once.
In some markets the same formulas appear under the name NutriCology. Same manufacturer, different label, which explains why both names turn up in reviews of the same product.
Why Allergy Research Group at BONO
We stock this brand because its formulas are made for the people other brands leave out. We judge form, dose and combination before anything goes in the assortment. Here that means vitamin C buffered with minerals for sensitive stomachs, delayed-release capsules so probiotic bacteria arrive further down the gut, and single nutrients you can dose yourself. We buy directly from the brand, so what arrives is authentic, and our compliance team checks every product before it goes live. We test products ourselves and independent labs spot-check batches. You can read how we select brands and products.
The honest part: this range is not cheap, and the iodine and glandular products are made for people who already know why they want them. If you are starting out, a straightforward vitamin C option or a probiotic is the more sensible first purchase. Give most products two to three weeks of daily use before you judge them.
Frequently asked questions
What is Allergy Research Group?
Allergy Research Group is an American supplement brand, founded in California in 1979 by biochemist Stephen Levine. It was one of the first companies to build a full range of hypoallergenic supplements, meaning formulas made without the ingredients that most often cause reactions. Its buffered vitamin C, introduced in the early 1980s, was designed for people with a sensitive stomach. The brand supplies practitioners worldwide and, in some markets, sells the same formulas under the name NutriCology.
What does hypoallergenic mean on these labels?
It describes what has been left out. Allergy Research Group formulates without gluten, dairy, soy, corn, nuts, eggs and other common food allergens, and without added colours and unnecessary fillers. The aim is a product that people with food sensitivities can still tolerate. It is a lower risk, not a guarantee. Anyone can react to any ingredient, including a plant extract or a capsule material, so read the full ingredient list on the product page before you buy.
Are Allergy Research Group supplements vegan?
Some are, many are not. A large part of the range uses plain vegetarian capsules and plant or synthetic ingredients. But several oil-based products use fish gelatin softgels, and the glandular range is made from beef or pork tissue. There is no single answer for the brand as a whole, so check the ingredient list of the specific product. If you follow a strict plant-based diet, the vitamin, mineral and amino acid products are the safer place to look.
Do I need a practitioner to buy these supplements?
No, you can order them yourself. Allergy Research Group is a practitioner-oriented brand, which means many products were designed to be used with professional guidance and some sit at higher strengths than a supermarket vitamin. For everyday nutrients such as vitamin C, zinc or a probiotic, that is not an issue. For high-strength iodine, hormone precursors such as DHEA or pregnenolone, and the glandular products, speak to your GP or a qualified practitioner first.
Which form should I choose: capsule, powder, softgel or tablet?
The form decides how easy the product is to dose and to swallow, not whether it works. Powders let you start with a small scoop and build up, which suits people who react easily. Capsules are the simplest for a fixed daily dose.
| Form | Main advantage | Suits |
|---|---|---|
| Vegetarian capsule | Fixed dose, no taste | Daily routine |
| Powder | Flexible dosing | Sensitive users |
| Softgel | Carries oils | Fat-soluble nutrients |
| Scored tablet | Can be halved | Stepped intake |
Can I combine these products with supplements from other brands?
Yes, and the single-nutrient design makes that easier. Because most products hold one nutrient, you can see exactly what you are taking and avoid doubling up. Add the totals across everything you take, including any multivitamin, and watch the nutrients with an upper limit such as iodine, zinc, selenium and vitamin A. If you take prescribed medication, check with your GP or pharmacist first, especially with iodine or enzyme products.
How long should I take a product before I judge it?
Give it two to three weeks of consistent daily use. Nutrient levels in the body change slowly, and a probiotic needs time to settle in the gut. Taking a product now and then makes it hard to tell whether anything changed. Fix it to an existing habit, such as breakfast, and keep the dose the same throughout. If a product does not sit well within the first few days, stop and check the ingredient list instead of pushing through.
How much iodine is in Iodoral, and what does UK guidance say?
Iodoral tablets are high strength: the 12.5 mg version contains many times the amount an adult needs each day. That is why the brand positions it for use under professional guidance. UK guidance is far more conservative for self-chosen supplements. If you simply want to cover the basics, a standard dose from our iodine range is the better fit.
| Reference | Amount |
|---|---|
| Adult daily need | 140 mcg |
| Supplements: unlikely to cause harm | 0.5 mg or less per day |
