Formulated to support the regulation of carbohydrate metabolism, improve insulin sensitivity, appetite control, and weight management. Minimal and clean composition: chromium picolinate as the sole active ingredient, with microcrystalline cellulose, magnesium stearate, and silicon dioxide as excipients. 1 capsule/day with a meal. 100 capsules = 100 days of use. Vegan. Gluten-free, sugar-free, salt-free.
Ingredients per capsule: Chromium Picolinate 1.66mg (0.2mg elemental Chromium, 500% NRV) + Bulking agent: microcrystalline cellulose + Anti-caking agents: magnesium stearate + silicon dioxide.
Benefits
Chromium picolinate: the form of chromium with the highest bioavailability and the most clinically studied:
Trivalent chromium (Cr³⁺) is an essential trace element that enhances insulin action at the level of its membrane receptor. Of the multiple forms of chromium available in the supplement market — chromium chloride, chromium nicotinate, chromium picolinate, chromium polynicotinate — chromium picolinate (chromium chelate with picolinic acid, a tryptophan metabolite) is consistently the form with the highest documented oral bioavailability: picolinic acid forms a stable and neutral chelate with Cr³⁺ that resists hydrolysis in the acidic gastric environment and is absorbed by enterocytes more efficiently than inorganic chromium chloride. Bioavailability studies have documented that chromium picolinate has 10 to 50 times higher intestinal absorption than chromium chloride. Additionally, chromium picolinate has lower renal excretion than other forms, resulting in greater tissue retention after absorption.
The chromodulin mechanism: how chromium enhances insulin signaling:
The mechanism of action of chromium in insulin sensitivity is mediated by chromodulin (also known as LMWCr — Low Molecular Weight Chromium-binding Substance), a 1.5 kDa oligopeptide composed of four amino acids (glycine, cysteine, aspartic acid, and glutamic acid) that binds to 4 Cr³⁺ ions in its active form. Chromodulin is activated by chromium and directly stimulates the activity of the insulin receptor tyrosine kinase — the intrinsic enzyme of the insulin receptor that initiates the intracellular insulin signaling cascade by phosphorylating tyrosine residues on the receptor itself and on IRS-1/IRS-2 substrates. In practical terms, chromodulin amplifies the insulin signal at the receptor level, which results in greater glucose uptake by target tissues (muscle and liver) for the same plasma insulin concentration — the "insulin sensitizing" effect. The EFSA has approved the specific health claim for chromium: "Chromium contributes to the maintenance of normal blood glucose levels" (EC Regulation No 432/2012).
200mcg per capsule = 500% NRV: the effective dose with a safety margin:
The dose of 200mcg of Chromium per capsule is the most clinically studied supplementation dose for effects on blood glucose and insulin sensitivity — and represents 500% of the European NRV (40mcg/day). The reason for using a dose so much higher than the NRV is that the NRV was established for preventing clinical deficiency in sedentary populations, while the pharmacological dose needed for effects on insulin sensitivity is significantly higher. The meta-analysis by Tian et al. (2013), published in Obesity Reviews with data from 15 clinical trials, documented that chromium supplementation (average doses of 200 to 1000mcg/day) reduced fasting blood glucose and HbA1c in people with type 2 diabetes and pre-diabetes, with a greater effect at higher doses and in people with greater basal insulin resistance. The dose of 200mcg/day is the dose with the highest number of positive studies and the best safety profile — EFSA and FDA consider doses of up to 200mcg/day as safe for use in supplements.
Blood glucose regulation and appetite control: the two practical benefits of chromium:
Chromium has two practical effects of greater relevance for athletes and people managing their weight. The first is post-prandial blood glucose regulation: by improving insulin sensitivity, chromium reduces the magnitude of blood glucose peaks after carbohydrate-rich meals and accelerates the return of blood glucose to basal levels — reducing post-prandial reactive hypoglycemia, which is one of the main causes of sugar cravings and excessive hunger between meals. The second is appetite control: multiple studies have documented that chromium picolinate supplementation reduces appetite, especially the desire for sugary and processed foods (cravings for high GI carbohydrates) — which is especially relevant for people in the cutting phase or caloric restriction where managing cravings is one of the main challenges for diet adherence.
Support for carbohydrate and fat metabolism:
In addition to its effects on blood glucose and insulin sensitivity, chromium has effects on lipid metabolism: it improves the lipid profile (reduction of triglycerides, increase in HDL) in some studies, possibly via improved hepatic insulin sensitivity which reduces de novo lipogenesis (synthesis of triglycerides from excess glucose in the liver). For athletes in the mass gain phase, greater insulin sensitivity maximizes glucose and amino acid uptake by muscles after training (favorable nutrient partitioning effect) — more nutrients for muscles, less for adipose tissue.
100 days of use at 1 capsule/day: the longest-lasting continuous support supplement:
With 100 capsules per pack and a dose of 1 capsule/day, Quamtrax's Chromium Picolinate offers 100 days of use per pack — one of the longest-lasting supplements per pack in the Quamtrax portfolio, making it one of the most affordable per day of use.
Uses
Recommended dose: Take 1 capsule per day, preferably with the main meal (or with the most carbohydrate-rich meal of the day). Taking it with meals improves absorption and maximizes the synergistic effect of chromium with the post-prandial insulin peak. 100 capsules = 100 days of use.
