Health Benefits

Thyroid Optimization

Provides the essential raw material for converting T4 thyroid hormone into its active T3 form.

Master Antioxidant

Directly fuels the glutathione peroxidase enzyme system to neutralize free radicals.

Neural Protection

The high selenium and magnesium content supports long-term cognitive health and mood stability.

Preparation Guide

1

Raw and unsalted versions preserve sensitive fatty acids like Omega-3s.

Best For: Maximizing nutrient absorption and digestibility

2

Alternative Usage

Best For: Nut/seed butters (without added sugars) are a viable alternative.
