I would get a wider test of hormones to include things like free T (for which I think you need SHBG and Albumin results). If it bugs you, its worth a test rather than thinking on it for months or years. It shouldn't cos that much to buy yourself a test kit, take it to a phlebotomist and then post the sample to a lab and then you will know.

I don't remember the treatment for high SHBG but it's out there over on reddit r/testosterone. I think they all take Boron and have good results. Keep in mind industrial food lacks essential nutrients.

Boron is a trace element that can be found in various foods and in the environment. Here are some natural sources where you can find boron:

Fruits:
    Prunes: One of the richest sources of boron.
    Raisins: Also contain a significant amount of boron.
    Avocados: A good source, especially beneficial for those looking to increase boron intake through snacks or additions to meals.
    Apples: Particularly in the skin.
    Peaches and Apricots: Both fresh and dried forms are good sources.
Vegetables:
    Almonds and Hazelnuts: Nuts generally contain boron, with almonds being particularly high.
    Broccoli: 
    Carrots: 
    Potatoes: Particularly if grown in boron-rich soil.
    Beans and Lentils: Chickpeas, for instance, provide a decent amount of boron.
Nuts and Seeds:
    Peanuts: Also peanut butter.
    Walnuts:
    Brazil Nuts:
Grains:
    Wine: In moderation, wine can contribute to boron intake.
    Honey: A natural sweetener that contains trace amounts of boron.
Other Sources:
    Coffee: While not extremely high, it does contain some boron.
    Leafy Greens: Like spinach, though the concentration can vary greatly depending on the soil.
Water: Depending on the geological area, drinking water can also be a source of boron, especially in regions where the soil has high boron content.

When aiming to increase your boron intake through diet, it's important to eat a varied diet rich in fruits, vegetables, nuts, and legumes. Keep in mind that while boron is beneficial, like all minerals, it should be consumed in moderation. Excessive intake of boron can lead to toxicity, so supplements should only be taken under medical advice. Also, the boron content in food can be influenced by the soil in which the food is grown, so there can be variation in the boron levels even within the same type of food.
